rocking piston

ARTICULATED PISTON

The articulated piston compressor utilizes the same operating principle as a conventional car engine piston. The articulated piston transfers rotational energy from a motor pulley into a reciprocating motion used to compress air in a cylinder.

As the piston moves down inside the cylinder, air is drawn in through a one-way intake valve. On the upward stroke, this air is exhausted through a one-way exhaust valve. Sealing of the piston to the cylinder is achieved by using two piston rings each backed with a spring to keep them in contact with the cylinder wall. A piston skirt is also used to guide the piston in the cylinder.

So on mute oil free air compressor maintenance and general breakdown maintenance problem more and more get the attention of the user. Will the mute oil free air compressor maintenance knowledge arrangement as follows, for the vast number of users.

1, the choice before buying. 

Choose the good quality, suitable for equipment required to use will be a lot less trouble. 1.1 suggest the user to select according to the technical advantages of factory production of products. As much as possible at the same time when the choice, should require manufacturers to provide detailed technical parameters, the parameter identification of incomplete, the lack of the detection of some technical projects, choose carefully. 1.2 according to the requirements of the equipment, the choice is a little bigger flow models, can avoid the fatigue the machine works. Increase the service life of the machine.

2, attaches great importance to the daily maintenance. The correct use and maintenance, can prolong the service life of air compressor, avoid or reduce the occurrence of failure.

2.1, mute oil free compressor itself does not contain any oily substances, avoid by all means is to add any lubricating oil and oily substances.

2.2, in strict accordance with the air pressure on the calibration of the rated voltage, frequency, load of work, the effect will be better and safer.

2.3, when not in use from work, get into the habit of timely cut off power supply. Mobile air compressor or other equipment connection, must cut off power supply. 2.4, must according to the factory setting of pressure within the scope of operations (general factory set the maximum pressure as 8 Bar, safety pressure relief 8.8 Bar), or gas tank explosion can be dangerous. (need special pressure, please contact factory custom)

2.4, must according to the factory setting of pressure within the scope of operations (general factory set the maximum pressure as 8 Bar, safety pressure relief 8.8 Bar), or gas tank explosion can be dangerous. (require special pressure, please contact the manufacturer to customize)

2.5, pay attention to the supply voltage and air compressor brand logo. Power supply voltage is higher than the voltage applied to the air compressor, may cause personal injury and damage, air compressor, power supply voltage is lower than the air compressor applied voltage, will cause a bad start, even damage the motor.

2.6, should be cleaned in time according to the use of filter, regular check accessories, cables, damage the replaced immediately. Should keep the machine clean dry non-stick oil, so as to give full play to its performance. Air compressor when not in use, should put off the air in the store jar, drainage of sewage in the store jar, stored in a dry environment.

2.7, timely drainage of sewage in the store jar, suggested that emissions should be at least once a week.

2.8, the correct use of the environment: air compressor normal use environment in 5 ℃, 40 ℃, shall not be placed in a place without shade not working in the damp and dark place, rigorous in store flammable and explosive liquid gas and dust, volatile place to work. Maintain a clean and tidy environment, and avoid unnecessary accidents.

2.9, please regularly inspect and replace inlet filter appropriately, general operation 300 hours after an inspection, the user check frequency according to the condition of use to decide on their own. Keep the filters and muffler clean can avoid most of the fault, don't clean the filter can reduce the service life of the performance of the compressor and compressor.

3, general failure and its elimination.

Table 3.1, general fault guidance

Table 3.2 common faults:

A, air compressor working away, but the supply is insufficient, air compressor, let gas tank pressure down A bit. With the external ear air compressor pipes, storage tanks over compressor gas pipelines, one-way valve. The relief valve, pressure switch connection place for air. As to rule out the problem that may be the nose cup wear or more than the rated flow, machine overworking. As for the cup damage will need to change the cup, cup life in three years or so commonly.

B, air compressor, intermittent work, insufficient gas supply. This is the cause of the problem: a lack of voltage. Start a buzzing sound. Such as observing her running current is too large at this time. Without oil head work minimum voltage is 200 v, lower than the voltage can be difficult to start the nose, a kick-off meeting for frequent cause temperature rise of the nose. The final circuit protection downtime. Until the temperature drops and boot. For regular voltage fluctuation area, suggest adding automatic voltage regulator. B start capacitor leakage. Compression head can also be activated for leakage, only the current big speed slower, because the current is big, cause the nose fever quickly, soon head protection downtime. This problem in a new can, to the same number but should pay attention to UF, bigger than the little is bad.

C, air compressor with each work to put the pressure of the storage tanks in the zero pressure before they can start the work. Otherwise can't start, can see turn slowly, when electricity is buzzing noise. Current is also big. This is because the one-way valve is blocked, the location a joint head out of the trachea (or called high pressure pipe) storage tanks on the other side, there are three exports. Its role is to make the nose of the gas can only into the tank and tank gas doesn't come out, its internal is a spring and a film. Such as dirt sticking film, will cause reverse leakage, then head secondary start will give high pressure can't start. The solution is to use the wrench will check valve bonnet open please wash after the same back then.

D, the function of air compressor work, but the noise due to the obvious larger than the original. Whether this beyond a machine accessories as a loose again after check the running current is normal. Build such as normal, are generally use a number of years, oil free compressor place environment should as far as possible away from the dusty places, unplug the power supply on a regular basis with high-pressure air blows away the surface and the dust inside the two blades, the noise is too large due to four motor bearing wear by dust, corresponding cup will also be affected. Replacement need special oil-free air compressor machine tools and accessories.

4, mute oil free compressor application range

Mute oil free compressor can be widely used in any industry need compressed air pure and fresh and clean, but medium must be air, under any circumstances can not be used for pumping flammable and explosive gas or operating in the environment containing these gases. Cannot be used for pumping liquids, solids particles, and any explosive, flammable substances.

Oil free compressor working principle:

Oil-free air compressor is miniature reciprocating piston compressor, motor single shaft drive compressor crankshaft rotates, through connecting rod drive, has the self-lubricating without adding any lubricant piston reciprocating motion, it consists of the inner wall of the cylinder, cylinder head and piston top surface of working volume will change periodically. Piston compressor piston from cylinder head start, the work within the cylinder volume increases gradually, at this time, the gas along the inlet pipe, pushed open the inlet valve into the cylinder, until the work gets to maximum volume, the inlet valve close; Reverse movement, piston compressor piston within the cylinder working volume shrinking, gas pressure, when the pressure in the cylinder is achieving and slightly higher than the exhaust pressure, the exhaust valve opens, the gas discharge cylinder, until the piston movement to the limit position, the exhaust valve closed. When piston compressor piston backward movement again, this process is repeated. Namely: piston compressor crankshaft rotates, the piston reciprocating at a time, one after another in the cylinder to realize the process of air intake, compression, exhaust, to complete a working cycle. Uniaxial duplex structure design of compressor gas flow at rated speed must be twice of the cylinder, and get a good control on vibration noise control.

The whole machine working principle:

The motor running, the air through the air filter into the compressor, the compressor will be compressed air, compressed gas by airflow pipe open the check valve into the storage tanks, pressure gauge pointer display, rise to eight Bar. Greater than 8 Bar, automatically shut down after the pressure, pressure switch induced motor to stop working, and at the same time, the electromagnetic valve will be pressure to the compressor head 0. The air pressure switch to assert, propane tanks still is 8 Bar, gas pressure in the gas through ball valve exhaust drive connection equipment work. Pressure drop to 5 Bar in the store jar, pressure switch open automatically by the induction, the compressor went back to work.

How to correctly choose mute oil free compressor

 Due to mute oil free compressor adopts the oilless self-lubrication technology, so its core parts piston ring and bearing on the material requirement is very high, has struggled to get a good solution. With the progress of science and technology, some special wear-resistant materials used, the technical barrier is breakthrough. In less than 10 years, mute oil free compressor first born in Europe, because of its environmental protection and energy saving, low noise, without any oily substances, compressed air quality characteristics of pure and fresh, clean, safe and durable, popularized and applied widely in European and American countries. In 2002, Ryan, mechanical and electrical first silent air compressor imported from German production technology, won many national invention patents, for domestic mute oil free air compressor vendors would provide technical support, soon get promoted in China. Get rid of the imports have been awkward situation.

But, because of some domestic manufacturer technology is not standard, manufactured, produced the mute oil free compressor can not meet the international standards. So how to correctly choose mute oil free compressor?

First be clear what is mute oil free compressor, understand how it works.

The mute oil free compressor host adopt miniature reciprocating piston compressor, if not this type, you can be sure judgment does not belong to this kind of air compressor mute oil free air compressor, air quality could not reach the requirements of mute oil free compressor. Mute oil free compressor working principle of the host: single shaft drive compressor crankshaft rotates, through connecting rod drive, has the self-lubricating without adding any lubricant piston reciprocating motion, it consists of the inner wall of the cylinder, cylinder head and piston top surface of working volume will change periodically. Piston compressor piston from cylinder head start, the work within the cylinder volume increases gradually, at this time, the gas along the inlet pipe, pushed open the inlet valve into the cylinder, until the work gets to maximum volume, the inlet valve close; Reverse movement, piston compressor piston within the cylinder working volume shrinking, gas pressure, when pressure in the cylinder reaches and slightly higher than the exhaust pressure, exhaust valve.

The second is the mute oil free compressor have those parameters requirements, is correct and complete.

If technical parameter identification is complete, the right. According to international practice identifying parameter contains metric units and American units. For example, Ryan, mechanical and electrical parameter identification is very formal and accurate. Parameter identification is simple, because there is no related test equipment, can't do such a test of technology parameter, or some parameters can not meet the general standard of technology, therefore, when the choice it is recommended that you require manufacturers to provide detailed parameters, so that you make the right choice.

One final note is in line with the domestic industry standard, whether through national mandatory technical certification

Host whether to pass 3 c and industrial product license certification. Most manufacturers are now passed the certification of the CE of some foreign countries, such as, but because do not conform to the domestic industry standard, not through domestic compulsory certification, there may be a risk when using.

Medical mute oil free compressor technology standard of environmental protection

According to authoritative organization investigation, human in the process of less than 300 years of industrial and consumes more than 70% of the resources on the earth. So, mankind will soon face the situation. Therefore, in recent years, countries around the world are vigorously promote the development of environmental science and technology. Air compressor industry in nearly 10 years of development of science and technology, also appeared a mute oil free compressor, this one out, environmental protection and energy saving of air compressor is widely used in many industries. So, mute oil free compressor includes those environmental protection science and technology?

A ,environmental protection should be energy-saving pioneer.

Scientific design of the compressor cylinder and quality control of the motor, piston ring, transmission system, can greatly improve the gas production unit power. Automatic switch, as well as simple operation procedure, can reduce power consumption.

Second, tenvironmental protection - output air pure and fresh and clean.

No oil lubrication technology application, processing and storage tanks with gas compressor interior walls and internal coating processing technology, with good air filter and oil-water separator, guarantee the output of the air cleaner, pure and fresh. If equipped with thermal regeneration dryer, also can ensure that the dry air without water.

Three, environmental protection - lower noise

Noise control technology in a more reasonable compressor working process design, at the same time, air inlet quieter to prevent and remove the good and the compressor vibration pad configuration is also key. Lower noise control, sound box is equipped with a sound absorption effect.

Four, environmental protection - stable and durable

Stable performance, even in extreme conditions can keep certain work time, reduce or not out of order, to ensure a longer use time, for customers to save cost in operation and maintenance, is the embodiment of the environmental protection.

Five, the environmental protection - packing also to conform to the requirements of environmental protection

Choose reusable or biodegradable packaging materials, in the case of ensure transportation safety at the same time, use less as far as possible the slick packaging materials.

Six,environmental protection products, environmental protection should be environmentally friendly factory to produce

Not only to ensure that the manufactured products is environmental protection, at the same time, the factory also must be clean and tidy, pay attention to the workers' working environment. Especially do not arrange production sewage and litter waste, garbage, pay attention to the maintenance of factory environment.

Laboratory use mute oil free compressor

What is a laboratory using a mute oil free compressor

Refers to the fit (colleges and universities, research institutions, etc.) in the laboratory environment to use air compressor, machine precision, reliability and environment protection halcyon, compressed air pure and fresh and clean. Displacement in less than 1 m3 / min laboratory use air compressor is more miniature reciprocating screw air compressor, also known as mute oil free compressor, foreign also called mini screw swing type air compressor. Its working principle is: motor drive shaft compressor crankshaft rotates, through connecting rod drive, has the self-lubricating without adding any lubricant piston reciprocating motion, it consists of the inner wall of the cylinder, cylinder head and piston top surface of working volume will change periodically. Piston compressor piston from cylinder head start, the work within the cylinder volume increases gradually, at this time, the gas along the inlet pipe, pushed open the inlet valve into the cylinder, until the work gets to maximum volume, the inlet valve close; Reverse movement, piston compressor piston within the cylinder working volume shrinking, gas pressure

Mute oil free compressor technique used in laboratory indicators

Higher gas production: refers to the unit under the power of compressed air emissions, this is a very important indicator, the user when the choice to do more comparison. With gas production under the higher power that the machine design more scientific, more environmental protection, energy conservation, stability and durability at the same time will be better. Exhaust pressure, according to industry standards to achieve 7 Bar, at present most do 8 Bar, but do like Ryan, mechanical and electrical 0 to 8 Bar adjustable manufacturer is one of the few. Air drying, cleanliness: no oil lubrication technology application, processing and storage tanks with gas compressor interior walls and internal coating processing technology, with good air filter and oil-water separator, guarantee the output of the air cleaner, pure and fresh. If equipped with thermal regeneration dryer, also can ensure that the dry air without water. Here are domestic AITOP ait brand laboratory dry air compressor in the installation of air quality, for users to reference: Dew point to 40 ℃, 70 ℃ or less, or less clean air (particles) : 0.05 mu, or less degree of dry air (water content) 0.05 PPM or less.

The three basic types of air compressors are

The three basic types of air compressors are

1.    reciprocating.

2.    rotary screw.

3.    rotary centrifugal.

These types are further specified by:

1.    the number of compression stages.

2.    cooling method (air, water, oil).

3.    drive method (motor, engine, steam, other).

4.    lubrication (oil, Oil-Free where Oil Free means no lubricating oil contacts the compressed air).

5.    packaged or custom-built.

Reciprocating Air Compressors

Reciprocating air compressors are positive displacement machines, meaning that they increase the pressure of the air by reducing its volume. This means they are taking in successive volumes of air which is confined within a closed space and elevating this air to a higher pressure. The reciprocating air compressor accomplishes this by a piston within a cylinder as the compressing and displacing element.
