Abstract

The invented reactive speed-control high-pressure rotor pump mainly includes driving shaft, blade type oil conveying pump, cam disk installed on terminal end of driving shaft and pump head, oil supply advance angle automatic regulating mechanism, reactive speed controller and throttle lever, oil quantity, the reactive speed controller is installed in pump cavity, and is mainly composed of a cylinder with oil inlet at one end, a piston and a piston rod are set up in the cylinder body. Its advantages are good stability, saving oil consumption, low wear, simple structure, low cost, etc.

Description

technical field [0001] The invention relates to an oil injection pump, in particular to a reactive power adjustable high pressure rotor pump. Background technique [0002] Diesel high-pressure rotor distribution fuel injection pump is a new type of pump that appeared in the late 1950s. Up to now, people have made many improvements to this pump, especially for the governor assembled in the pump. However, these improvements are all based on the mechanical centrifugal governor. No matter how it is improved, the mechanical centrifugal governor is still the most widely used in actual production and use. [0003] As the name suggests, the mechanical centrifugal governor must have mechanical power to work, and the governor will participate in speed regulation after the engine rotates, (such as image 3 As shown) the power is input through the transmission shaft (1) of the fuel injection pump, and the driving gear on the transmission shaft meshes with the driven gear on the governor...
