Choosing oil-lubricated or oil-free lubricating compressors is undoubted. Oil-free lubricating compressors have the least oil pollution to the gas. A reasonable choice should be to use oil-free lubricating compressors. However, due to the constraints of domestic self-lubricating materials, it is necessary to achieve High reliability: oil-free lubrication is not yet mature, although manufacturers have entered more than a decade ago. After trying, I finally returned to the oil lubrication program due to various reasons such as the domestic material foundation.
The utility model relates to a screw compressor with a screw sealing cavity, which is composed of: a compressor screw housing; two spiral rotors which are arranged to be meshed with each other by a spiral body arranged in the compressor screw housing, and the rotating shaft portion of the rotor is placed on the two spiral bodies At both ends, the rotating shaft portion of the spiral rotor is installed in the bearing housing at both ends of the compressor screw housing to prevent pressure loss. It is recommended that one end of the corresponding spiral end adjacent to the pressure end be extended as the intermediate portion of the corresponding shaft portion of the support portion, and the seal is located in the closed wall of the discharge end of the compressor screw housing, and the inner surface of the closed wall has an open annular groove.
In some years, some months can be used without air conditioning. In this case, you only need to put the season switch in the "OFF" position, which can prevent the loss of refrigerant and prevent the parts from rusting. In order to achieve a certain degree of lubrication of the internal components of the refrigeration system during the period of use, the refrigeration system must be started every other month. Run about five minutes each time. Before the start of each month or before the first run of the year, the following checks should be made; check if the V-belt is loose and damaged; check if the clutch pulley of the crankshaft pulley, tensioner and compressor is in a plane; check the air intake in the car. Check whether the filter on the mouth is clogged; check the surface of the compressor, such as dust and oil, and do the cleaning work; check and firmly install the nuts and bolts; check the relevant parts, wiring and connection parts for refrigerant leakage, such as The corresponding parts should be tightened.
