Share the seven curing methods of submersible sewage pump

Submersible sewage pump is in the form of motor Siamese, at the same time into the work under the liquid pump products, sewage can be long fiber, cloth, bags, belt, grass and other material tear, cut off, and then discharge smoothly, particularly suited to deliver a hard solid, fiber content of liquid and particularly dirty, sticky and slippery liquid. At ordinary times of diving sewage pump, therefore, must do maintenance work, to slow the abrasion of sewage pump. Take a look at below submersible sewage pump maintenance knowledge:

1, check the wearing parts: submersible sewage pump impeller, retaining ring, shaft sleeve, bearing seat is wearing parts, etc. You should take the pump parts removed, check whether the parts is in good condition. Damage and unqualified parts is strictly prohibited.

2, replace lubricating oil: open the sealed chamber and the inside of the motor oil hole screws, all the seal indoor and lubricating oil inside the motor, change new oil, to ensure normal work of lubrication system.

3, tear open pump shell rust prevention: before use, should open the pump shell at the next higher level, closing again after starting rotating impeller, in case the parts rust cannot be the normal starting and burning motor. The maintenance of water filling type motor is particularly important.

4, to ensure the bearing lubrication: the water filling diving sewage pump should be replaced check up and down bearing chamber of skeleton oil seal and lithium grease. To ensure the bearing long-term work under good lubrication condition.

5, make sure seal: agricultural diving sewage pump seal requirement is very strict, in replacing seal indoor lubricating oil, if you find oily turbidity and high water content, it must be whole replaced or sealing ring or replace the seal box, in order to ensure the sealing performance is good.

6, check the bearing: check the motor part of the upper and lower bearings, if discover wear or gap is too big, must be timely replace new bearing, it is forbidden to make use of "being".

7, drying machine, measured with 500 megohm meter diving sewage pump the insulation resistance of the winding and the shell if resistance less than 0.5 ohms, moisture should drive motor.

Above is the main diving sewage pump maintenance measures, before and after users in the use of submersible sewage pump, the above seven earnestly, must be able to protect the diving sewage pump performance, to make it better and faster service for everyone.
