3、要分为电与机两个方面，关于机的方面，主要把以前的维护记载调出来比对一下就晓得了。 其次就是电的方面了 ，要理解每台泵电机的功率，对他的控制系统有一定的理解。采用机械密封的双吸泵，必需保证轴封水的供给。严禁无水运转，否则机械密封将烧毁。
1. When the slurry pump works, the pump needs to be placed on the land, the suction pipe needs to be placed in the water, and the pump needs to be started. Mud pump and submerged slurry pump are limited by the structure. When they work, the motor needs to be placed on the water surface, and the pump is put into the water, so it must be fixed. Otherwise, the motor will be scrapped if it falls into the water. Moreover, because the length of the long shaft is generally fixed, the use of the pump device is more difficult, and the application place is subject to many restrictions.
2. If there is standby pump, it is better to use two pumps in turns. If card pump only need to repair the pump, can add a net in the water inlet, do not let too many impurities into the pump, so the probability of card pump will be much smaller!
3. It should be divided into two aspects: electric and mechanical. As for the mechanical aspect, it is mainly known by comparing the previous maintenance records Secondly, it's about electricity. We should understand the power of each pump motor and have a certain understanding of its control system. The slurry pump with mechanical seal must ensure the supply of shaft seal water. Do not operate without water, otherwise the mechanical seal will be burnt.
