3, cleaning the oil return check valve check valve from the valve body, ball, ball seats, springs and other components. The role of the oil return check 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, and then in action under internal pressure to return to the host for the next lubrication cycle. And contains a small amount of oil in the compressed air through the oil separator compressor manufacturer is again separated, then the 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 used in the design of a pipe inserted into the bottom of the oil separator by 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. For the reciprocating piston compressor mechanism, it can not eliminate the presence of inertial forces compressor manufacturers Which is good, so running vibration, high noise, the need for specialized fixed base when the larger piston compressor installation . A rotary screw compressor movement mechanism, well-balanced, vibration, low noise, no installed base. Reciprocating piston compressor is intermittent supply, gas pulsation when running large, high speed screw compressors, stationary gas, no gas pulsation, can meet the requirements of high volume users. Piston compressor basically no automatic control system. Screw compressors are perfect automatic control and protection system compressor manufacturer rankings, are mechanical and electrical integration products, to facilitate the equipment maintenance management, but also to maximize the reduction of energy consumption. Rotary screw compressors can tolerate high speed, so the structure is much smaller volume than the same displacement piston compressor, the same power of the compressor displacement is also much larger. Plus cooler inside the exhaust gas temperature is lower than the piston compressor is about 50 to 60 degrees. If you use too many aircraft types, too scattered, it is neither easy device management, but also increased the number of wearing parts, is bound to increase the cost of normal operation. While the dispersed arrangement is exacerbated by the pollution of the production environment. Piston compressor piston ring wear existence, running despite the oil scraper ring on the piston, but still there is a lot of oil went to the cylinder, the one with the gas discharge. Thus while reducing gas quality, it also increased the fuel consumption. Screw compressor systems with high-efficiency gas separation and filtration equipment compressor factory direct, high-quality supply, fuel consumption is low. Based on the above relevant circumstances, many domestic enterprises in the use of the low-pressure compressor, the phasing out of high operating costs, low reliability of the piston compressor, screw compressor with high efficiency Instead, in developed countries has become a reality. Based on the above said, in order to reduce production costs and increase economic efficiency, easy device management.
