RQVK speed governor with full-load power compensating function

Abstract

An RQVK speed governor with a full-load power compensating function comprises a speed governing handle, a limit piece, a plunger pair and a limiter, wherein the limit piece is in transmission connection with the speed governing handle, the plunger pair is in transmission connection with the limit piece, and the limiter limits the maximum bidirectional stroke of the limit piece. The RQVK governor is characterized in that compensating pieces made of low-abrasion-degree materials are arranged on the limit piece and at positions contacting with the limiter, and both the limit piece and the limiter are made of high-abrasion-degree materials. The RQVK speed governor with the full-load power compensating function has the advantages that decrease of oil supply quantity of the plunger pair at quick-abrasion stage can be compensated, and output power of an engine is guaranteed to be identical with a design value.

Description

technical field [0001] The invention relates to a governor, in particular to an RQVK governor with full load power compensation function. Background technique [0002] The schematic diagram of the RQVK governor is as follows: figure 1 As shown, the driver operates the speed control handle to drive the movement of the limit plate, and the limit plate drives the gear on the plunger pair through the oil quantity control rod with a rack to rotate. When the gear rotates, the plunger is driven to rotate in a circumferential direction. In this way, the positional relationship between the oil hole on the plunger and the plunger sleeve is changed, and finally it plays a role in adjusting the oil output of the plunger pair; the limit plate not only plays the role of driving the plunger pair, but also Cooperate with the limiter to limit the adjustable range of the governor, and its limiting effect is realized by the physical block between the limiter and the limiter; [0003] The...

AI Technical Summary

Problems solved by technology

[0003] The existing plunger pair technology is very mature, and its material and manufacturing process are relatively fixed. After the new plunger pair is put into use, normal wear and tear will inevitably occur, and the wear speed will be faster at the beginning of wear (this stage is defined as rapid wear stage), after the wear reaches a certain level, the wear rate slows down until the plunger pair is scrapped (regardless of the scrapping of other parts); due to the existence of the rapid wear stage, the circumferential stroke of the plunger pair is shortened , the actual fuel supply is lower than the design value, resulting in a correspondingly low engine power
