Take you to understand the structure of SQP series vane pump

The SQP series vane pump is also a light and compact pump, which proposes an oil pump with a casing made of aluminum-containing material and a movable molded part set in the casing, wherein the movable The molded part is at least partly made of a sinterable material comprising at least one austenitic iron-based alloy, and wherein the molded part made of a sinterable material has a The coefficient of thermal expansion is 60% of the thermal expansion coefficient.

There are three types of SQP series vane pumps: in-line type, distributed type and single type. No matter which type, the key to the oil pump lies in the word "pump". The quantity, pressure and time of pumping oil must be very precise and automatically adjusted according to the load. The oil pump is a component with fine processing and complicated manufacturing process. The oil pumps of general automobile diesel engines at home and abroad are produced by a few professional factories in the world.

Vane pump - mechanical structure

The main parts of the oil（vane） pump are: camshaft, roller body, rotating sleeve and ring gear, oil outlet valve and valve seat, and compression pipe connection, etc. They are carefully processed and matched with each other, and the diameter clearance is only 0.001-0.003mm. The pair of parts can only be replaced in pairs, not individually.
