3, cleaning the oil return check valve check valve from the valve body, ball, ball seats, springs and other components. Oil return way valve: Host compression of the mixture of oil and gas in the oil and gas tank first preliminary separation by centrifugal force, due to the weight of the oil is greater than air, solid and gas mixture most of the oil tank by the centrifugal force and fall Cottle air compressor brands, under the internal pressure of the role and then returned to the host for the next lubrication cycle. And it contains a small amount of oil in the compressed air through the oil separator separated again, this time oil separator the separated oil will fall to the bottom of the oil separator, in order to keep this part of the oil away with compressed air, the unit in the design insert the oil separator with the bottom of a pipeline through internal pressure, this part of the lubricating oil directly into the host, and there is a one-way valve on the pipeline, also known as the oil return check valve. Its role is to oil separator oil recovered smoothly without letting the host-to-host back to the oil and gas separator. (1) Removing the oil return single valve: in the body there is a junction, from where unscrew and remove the spring, ball, ball seat. (2) Cleaning oil return check valve: body wash, springs, ball, ball seat cleaning agents, as well as part of the check valve inside the filter, if the wash together. (3) the oil return check valve assembly: the installation of a reverse steps to remove the one-way valve. (4) one-way valve after completion of the cleaning process to be put aside into the air compressor. Do compressor bearings and damage statistics compressor brand identify compressor bearing damage problem common law, in order to accurately measure the specific proposed saving compressor bearings. Can be recorded from the following aspects: 1, compressor design and precision situation; 2, the compressor application; 3, lubrication and the sealing of the lubricating effect; 4, compressor and transmission, and other site conditions adjustment; 5, the bearing assembly 6, bearing in the form of damage and installed parts, etc; parts precision assembly and disassembly conditions of the situation. Bearing strength to match each part in ensuring the strength of the bearing housing (ie compressor bearing good rigid support), try to choose a load bearing capacity of the compressor. It should also optimize the design of the compressor bearing various part sizes depending on the application of working conditions, to ensure that all parts of equivalent strength compressor bearings to maximize the service life of the bearings. For example, the bearing housing wear deformation, the bearing outer ring cracked more field, you can thicken the wall thickness of the roller bearing outer diameter decreases, enhanced outer strength, in order to achieve maximum bearing life. Due to the use of high-quality bearing material presence of non-metallic inclusions compressor brand outlets, particularly the oxide inclusions, causing weakness bearing material strength, stress concentration, premature fatigue failure of the bearing. So, be vacuum degassing or remelting bearing steel, although high priced piston compressor bearing the brand, but less bearing damage, compressor operating rate increased, overall costs should be reduced.
