Maintenance rules about constant current pump

Constant current pump is widely used in the laboratory and chemical industry a pump, its maintenance matters are:
Add bearing lubricating oil to the bearing body, observe the oil level should be at the center line of the oil mark, and the lubricating oil should be replaced or supplemented in time.
Unscrew the water inlet plug of the constant flow pump body, and fill the water or slurry. Close the gate valve of the outlet pipeline, the outlet pressure gauge and the inlet vacuum gauge.
Start the motor and check whether the motor turns correctly. Start the motor, when the constant current pump normal operation, open the outlet pressure gauge and inlet constant current pump, as it shows the appropriate pressure, gradually open the gate valve, and check the motor load.
As far as possible to control the flow and head of the constant flow pump within the scope indicated on the sign, to ensure that the constant flow pump at the highest efficiency point operation, in order to obtain the maximum energy saving effect.
Constant current pump in the process of operation, bearing temperature can not exceed the environmental temperature of 35℃, the highest temperature shall not exceed 80℃. If the constant current pump is found to have abnormal sound, stop immediately to check the reason.
Constant current pump to stop using, first close the gate valve, pressure gauge, and then stop the motor. Constant current pump in the first month of work, after 100 hours to replace the lubricating oil, after each 500 hours, oil change once.
Often adjust the packing gland, to ensure that the leakage of the packing room is normal to drip leakage is appropriate.
Check the wear of the shaft sleeve regularly, and replace it in time after the wear is large. Constant current pump in the winter season when used, after parking, the lower part of the pump body water plug unscrewing the medium. Prevent frost crack.
Constant flow pump for a long time out of use, need to pump all disassembled.
