High Precision New Diesel Pump Head Rotor 146401-1920 Fuel Injection Pump Elements Engine Spare Parts

Diesel engine is the burning of diesel fuel to obtain the energy release engine, diesel engine has the advantage of large torque, good economic performance, the oil pump is one of the essential diesel engine devices, including oil pump, in the lubrication system, the role of the oil pump: oil pump role is to raise the oil to a certain pressure, forced to pressure to the engine parts of the moving surfaces, the structure of the oil pump can be divided into two types of gear-type and rotor-type, gear-type oil pump is divided into internal gear type and external gear type, the latter is generally referred to as gear-type oil pump. The oil pump structure can be divided into gear and rotor type two categories, gear type oil pump is divided into internal gear type and external gear type, the latter is generally known as gear type oil pump. Technical problems in the prior art: 1. In the existing oil pump, the active gear and the driven gear mesh with each other and rotate, and the teeth and tooth surfaces of the two generate contact friction, resulting in high heat on the contact surfaces, which affects the service life of the gears due to the lack of heat dissipation measures; 2. The teeth and tooth surfaces of the two generate contact friction, which is prone to abrasion and wear, and the prolonged use of the two affects the effect of the mesh of the active gear and the driven gear and is not convenient for use. inconvenient to use. In order to solve the above problems, a new oil pump for diesel engine is proposed in this application.
