Abstract
The invention discloses a method for grinding a light remanufacturing engine. On the basis of the original gradual and circular change of the rotating speed, a grinding load is increased and the grinding process is divided into two stages so as to realize gradual change of the stages in total, so that the rapid grinding method for the light remanufacturing engine is provided. Through the method for grinding the light remanufacturing engine disclosed by the invention, the grinding efficiency is improved and the grinding time is reduced, so that the reception time is effectively shortened and the reception cost is reduced.
Description
Technical field
The present invention relates to motor break-in field, in particular, relate to the light-duty break-in method that motor is checked and accepted of making again.
Technical background
It is to make the engine product that reaches working life it meet or exceed the course of working of raw product performance through reparation and technical innovation that motor is made again.American-European each developed country has all realized the industrialized development that junked-auto is made again, and is ripe and perfect relatively from the re-manufacturing technology to the NBS.The pilot work that China just made since 2008 more also launches with the studies that manufacturing is relevant more fully.
More to new engine at present with the break-in method that rebuilds an engine, and start late owing to motor is manufactured on China again, less to the break-in method of making motor again.Use traditional little load, slow-speed of revolution break-in method to carry out break-in, need running-in time more than 10 hours just can make to make motor again to reach best break-in state.
The break-in method is the avatar of motor break-in, mainly comprises three contents, i.e. running in speed, running-in time and break-in load.The break-in of motor on stand is to realize the abundant break-in to motor through continuous change rotating speed, load and time.Be illustrated in figure 1 as the plotted curve that each parameter of a kind of medium and small load break-in method changes.Through practical application, use medium and small load to realize need carrying out 6 continuously more than the circulation to making the abundant break-in of motor again, total running-in time was above 12 hours.
Summary of the invention
The objective of the invention is for the light-duty motor of making again provides a kind of break-in method fast, improve break-in efficient, reduce running-in time, check and accept cost with reducing thereby effectively reduce reception time.
The light-duty motor break-in method of making again of the present invention; Be achieved through following technical proposals, on the basis of original rotating speed echelon, circulation change, increase the break-in load and be divided into the stage to break-in and carry out; Realize that each stage echelon generally changes, concrete steps are following:
A. first circulation: a. moves 10 minutes under idling speed; B. at the 1000r/min rotating speed, operation is 10 minutes under Rate of load condensate 15% situation; C. at the 1500r/min rotating speed, operation is 10 minutes under Rate of load condensate 20% situation; D. at the 2000r/min rotating speed, operation is 10 minutes under Rate of load condensate 25% situation; E. at the 2500r/min rotating speed, operation is 15 minutes under Rate of load condensate 35% situation; F. at the 3000r/min rotating speed, operation is 15 minutes under Rate of load condensate 40% situation; G. at the 3500r/min rotating speed, operation is 10 minutes under Rate of load condensate 50% situation; H. at the 4000r/min rotating speed, operation is 10 minutes under Rate of load condensate 55% situation;
B. second circulation: a. moves 5 minutes under idling speed; B. at the 1500r/min rotating speed, operation is 5 minutes under Rate of load condensate 20% situation; C. at the 2000r/min rotating speed, operation is 5 minutes under Rate of load condensate 25% situation; D. at the 2500r/min rotating speed, operation is 5 minutes under Rate of load condensate 30% situation; E. at the 3000r/min rotating speed, operation is 5 minutes under Rate of load condensate 40% situation; F. at the 3500r/min rotating speed, operation is 10 minutes under Rate of load condensate 50% situation; G. at the 4000r/min rotating speed, operation is 5 minutes under Rate of load condensate 60% situation; H. at the 4500r/min rotating speed, operation is 5 minutes under Rate of load condensate 70% situation;
C. the 3rd circulation: a. moves 5 minutes under idling speed; B. at the 1500r/min rotating speed, operation is 5 minutes under Rate of load condensate 30% situation; C. at the 2000r/min rotating speed, operation is 5 minutes under Rate of load condensate 35% situation; D. at the 2500r/min rotating speed, operation is 5 minutes under Rate of load condensate 45% situation; E. at the 3000r/min rotating speed, operation is 5 minutes under Rate of load condensate 50% situation; F. at the 3500r/min rotating speed, operation is 10 minutes under Rate of load condensate 60% situation; G. at the 4000r/min rotating speed, operation is 5 minutes under Rate of load condensate 75% situation; H. at the 4500r/min rotating speed, operation is 5 minutes under Rate of load condensate 80% situation; F. at the 5000r/min rotating speed, operation is 5 minutes under Rate of load condensate 90% situation.
The present invention provides a kind of break-in method fast for the light-duty motor of making again, has improved break-in efficient, has reduced running-in time, checks and accepts cost thereby effectively reduce reception time with reducing.
