在研究提高剎车副寿命的同时,我们发现国产钻机在使用中均没有充分发挥水剎车效能,因而剎车副的使用寿命短。所以研究充分发挥水刹车的效能,是一个与剎车副的研究有密切关系的研究课题。 目前,在钻机辅助剎车方面虽然已有性能良好的电磁剎车在使用,但水刹车由于具有结构简单、制造容易、使用可靠和寿命长等优点,国外还在使用。国产钻机除有少数几台在试
In the study to improve the life of the brake, we found that domestic drilling rigs are not fully used in the performance of water brake, brake and therefore the service life is short. Therefore, research to fully exert the effectiveness of water brake is a research topic that is closely related to the research of brake pads. At present, although there are well-performing electromagnetic brakes used in the auxiliary braking of drilling rigs, the water brakes are still in use due to the advantages of simple structure, easy manufacture, reliable use and long service life. In addition to a few domestic drilling rig in the test
