Ammonia refrigeration compressor oil pump
Thread Content
What kind of structure does the oil pump have?
It’s either a gear pump or a screw pump.....
It’s a three-screw lubricating oil pump, not a gear pump. In a typical gear pump, there are two circular sections on the pump casing, along with male and female rotors; the male rotor is connected to a coupling that is linked to the motor. This pump, on the other hand, has only one circular section – it must be a three-screw lubricating oil pump
Do you have any relevant materials or pictures of three-screw lubrication oil pumps that you can share with us?
