Printed Oil pump for WD615 Diesel engine AZ1500070021

Concept of oil pump
Oil Pump, Oil Pump) in the lubrication system, which forced the Oil from the Oil pan to engine moving parts of the device.

Purpose of the oil pump
Used to make the oil pressure and guarantee a certain amount of oil, to the friction surface forced feed components. Widely used in internal combustion engine oil pump gear type and rotor type. The gear oil pump has simple structure, convenient processing, reliable operation, long service life, high pressure oil pump, is widely used. The rotor pump rotor complex shape, multi-purpose powder metallurgy. This kind of pump has the advantages of gear pump also but compact structure, small volume.

Role of oil Pump

1) the function of lubrication oil pump in the system oil pump is to increase the oil to a ertain pressure, forcing pressure to various parts of the activity's engine.

2) the structure adopts gear oil pump.

3) engine, the crankshaft drives the driving gear transmission, passive gear to rotate in the opposite direction. Oil and oil absorption cavity wall along the backlash and pump pressure into the oil chamber. Oil for oil absorption cavity was taken away by constantly, so the oil absorption cavity suction, continuously the oil suction within the oil sump oil absorption cavity, and at the same time to certain pressure oil pump into the oil way.

Advantages of oil pump

1) Structure: Simple structure, small volume, light weight, large amount of oil. Cycloid rotor pump system adopts the structure of the inner and outer rotor meshing, tooth number, less compact structure size, without other isolation components can form a sealed cavity, the number of parts.

2) Movement characteristics: Smooth running, low noise. Cycloid rotor pump, a difference of tooth in inner and outer rotor teeth, they do relative movement, small tooth surface sliding speed, mesh point in constant along the inner and outer rotor tooth profile move, therefore, two rotor tooth surface wear little to each other. Due to the discharge of oil and oil absorption cavity envelop Angle is big, close to 145 °, oil suction and discharge time is sufficient, therefore, the flow movement is smooth, flat, and noise is significantly lower than the gear pump.

3)High-speed characteristics: Good high speed performance. For general involute gear pump, if the speed is too high, is because of the action of centrifugal force will cause tooth form "holes" GuChong oil shortage, decrease the pump efficiency, therefore, its speed rarely exceed 3000 RPM, circumferential velocity within 5 ~ 6 m/s. For cycloid rotor pump, the suction oil discharge Angle range is big, in the high speed rotates, the effect of centrifugal force is advantageous to the oil in the tooth valley filling, no harmful "holes" phenomenon, therefore, cycloid rotor pump speed range can be in the hundreds of turn to nearly everything.
