Leaking oil-free air compressor filler components analysis
Oil-free air compressor gas seal components leaking common phenomenon:
the outside of the housing of the air seal, bolts along a fixed gas seal leakage or seepage;
along the trolley leaking or dripping inside the gas seal seepage both cases.
1, leaks or drops in the gas seal assembly outside the housing along the fixed gas sealing bolt infiltration caused by reasons of external leakage of the gas seal assembly housing is due to the aging of the O-ring of the lower end of the gas seal assembly. Caused Mifengbuyan, so that the cooling water leakage. Then if oil scraper ring damage or Mifengbuyan of the, it is possible to make the cooling water along Rod inflow sump, resulting in oil emulsification, and in severe cases can cause the crankshaft locking bush-burning and other accidents. Commonly used to replace the appropriate O-ring work to solve this kind of problem.
In addition, the cylinder block casting defect is caused by one of the reasons for leaking gas seal components outside of the housing. Cylinder aging or due to the casting, the cylinder breakage, cracks or trachoma, can also cause leakage of oil-free air compressor gas seal components outside of the housing.
Deal with these problems, a concrete analysis of specific treatment, usually welding to repair or replace the cylinder. Repaired cylinder hydrostatic test must be carried out to ensure the safety of the cylinder.
2 caused the internal components of the gas seal along the trolley muddy water or drops of seepage along the compressor the trolley running water or drops of infiltration, when severe leakage of the internal components of the gas seal leakage not more common, but the reason is more complicated, mainly as follows: when, if coupled with damage to the oil scraper ring, cooling water is likely to enter the sump internal, caused by the serious consequences of the same as described above. The common cause of the following aspects:
Aging of the upper end of the assembly housing

The common cause of the following aspects:
Aging of the upper end of the assembly housing
(1) a gas seal with the cylinder connected at the mat or mat thinner causing Mifengbuyan, so that the cooling water into the internal cylinder. This phenomenon in the piston down, the most obvious. When dealing with this type of problem, the commonly used method is to replace the gasket. Replacement cushions, it is best to use the depth gauge measured the size of the top of the cylinder gas seal assembly housing, according to the measured data to determine the increase in the right mat, if necessary, can also be coated with a layer of polymer sealant to increase the sealing effect.
(2) cylinder bed damaged or Mifengbuyan the the one of the reasons is also caused by leaking gas seal assembly. When the cylinder bed damaged or the cylinder head bolts are not tightened in accordance with the provisions of torque, and will cause cylinder leaking. In the piston during operation, cooling water may be the direction of the piston rod into the gas sealing, causing leakage. We should pay more attention to this problem, if the severe water cylinder bed, may cause the piston cylinder, even to appear top cylinder vicious accident. The method of dealing with such problems is to replace the cylinder bed or torque required to re-tighten the cylinder head bolts.
(3) gas seal assembly housing can also cause damage, blisters, cracks, leaking gas seal assembly. As the gas seal assembly housing in contact with the cooling water for a long time, in the oil-free air compressor work, cooling water temperature is high: when the compressor does not work, the water temperature is low, this water temperature alternately changing phenomenon easily compressor air seal assembly housing have a scale, severe appear the phenomenon of cavitation, resulting in the casing perforations. In particular, some casting defects such as trachoma, stomatal weak places, the most prone to breakage, cracking or perforation, may cause leakage of cooling water. Causing oil emulsification, to cause crankshaft strain, bush-burning and other accidents. Deal with such issues is timely repair or replacement of the air seal assembly housing.
Leaking oil-free air compressor filler components, though not common, but if the event tend to give oil-free air compressors have serious consequences. Especially for oil-free air compressor disrepair due to aging equipment, air sealing components most prone to water leakage, therefore, carry out regular inspections of these oil-free air compressors, and would be prepared for, it is very necessary.
