The oil pump can be used as a process pump, a conveying pump, or a circulating oil pump for screw-type compressors, as well as a pump for supplying oil to hydraulic stations and other equipment. It integrates reciprocating and rotor type, and has the characteristics of high speed, large flow, high pressure and stability, long working life and so on.

Vertical oil pump for ammonia screw refrigeration compressor

Introduction

     2ZH oil pump is an executive element that provides pressure source for petroleum, chemical, refrigeration, pharmaceutical and other industries. The oil pump can be used as a process pump, a conveying pump, or a circulating oil pump for screw-type compressors, as well as a pump for supplying oil to hydraulic stations and other equipment. It integrates reciprocating and rotor type, and has the characteristics of high speed, large flow, high pressure and stability, long working life and so on.


2ZH oil pump work principle:

     The crankshaft drives two pistons that are perpendicular to each other on the same rotating cylinder to make planetary rotational movements. The colleague's cylinders organically rotate at a uniform speed and alternately cycle through the pump inlet and outlet to form continuous suction and discharge of liquid.

oil pump

Notes on the use of oil pumps:

     1. The coaxiality tolerance between the oil pump shaft extension end and the power source output shaft is within 0.03mm, and it should avoid direct transmission by radial force and belt. The connection uses an elastic sleeve pin coupling.

     2. There are two ways to mark the oil pump. One: The arrow on the pump casing indicates the direction of rotation. At this time, looking at the extended end of the oil pump shaft, if it is counterclockwise, it goes in left and right out; if it is clockwise, it goes in right and left. Second: the pump casing is marked with "IN" and "OUT". At this time, when looking at the oil pump shaft extension, if "IN" is on the left and "OUT" is on the right, the rotation direction is counterclockwise; if "IN" is on the right " OUT "is on the left, the rotation direction is clockwise.

     3. The oil pump's oil inlet pipeline must be tightly sealed, no air leakage is allowed in any part, otherwise it will cause system vibration and noise.

     4. The oil pump's suction pipe is equipped with a two-stage oil filter to ensure the service life of the pump.

     5. The viscosity of the working medium is related to the working pressure environment and temperature. Generally, the kinematic viscosity of the medium is 27-33CST at 50 ℃.
