How to operate and install YW liquid displacement pump
When the YW liquid sewage pump is working, because it is a vertical liquid structure, it needs to be completely immersed in water, the depth of the liquid can reach 0.5~m, and the products can be customized according to the requirements of the use environment. The following points are the following analysis for the operation problems of Changrun intelligent manufacturing engineers:
1. The liquid sewage pump must be vertically installed on the cover plate of the liquid material pool, and it is not allowed to be placed diagonally.
2, the manual pump for the liquid sewage pump, review whether the pump can have a stuck scene, and review whether the vortex direction of the liquid sewage pump motor can be consistent with the pump request.
3, the liquid sewage pump must be immersed in the liquid, do not deliquid idling.
The above are the steps that need to be understood when the operation, next talk about how to install the liquid sewage pump, first of all, the glass fiber reinforced plastic liquid pump should be installed vertically, the flat cover plate of the pump is installed on the equipment or liquid storage tank flange seat, before starting to run, start the coupling by hand, check whether there is a blockage phenomenon, and whether the rotation is flexible. Secondly, pay attention to the liquid level is not lower than the pump shell, it is strictly prohibited to operate without medium and reverse, otherwise the shaft bush and sleeve in the pump body are damaged due to lack of liquid lubrication, and violent vibration or abnormal sound is found during operation, immediately stop for inspection. Then in the maintenance, first remove the liquid pump from the tank, remove the lower pump housing, knock off the lower shaft sleeve and impeller (pay attention to the anticorrosive layer on the pump shaft), remove the motor and frame, loosen the six hexagonal bolts on the upper bearing seat, and then pull out the positive pump shaft and bearing parts together for maintenance.
