Talk about the correct use of corrosion resistant submerged pump

Before using the corrosion resistant submerged pump, you must read the operating instructions of the corrosion resistant submerged pump carefully to understand the specific operation steps so as to use the corrosion resistant submerged pump product correctly. The operation steps of the corrosion resistant submerged pump are to first open all the inlet valves of the corrosion resistant submerged pump. After the pump cavity of the corrosion resistant submerged pump is filled with liquid, close the outlet valve and start the motor. After the motor rotates normally, the outlet valve can be gradually opened and adjusted. to the required condition. Note that the exhaust valve must be opened when the self-priming corrosion resistant submerged pump is started, and the outlet valve should be opened quickly after the normal operation of the motor to prevent the air from the inlet pipe from being exhausted, causing cavitation in the corrosion resistant submerged pump, resulting in corrosion resistant submerged pump. The phenomenon of loud vibration and noise cannot absorb water.

The method of using the corrosion resistant submerged pump can be divided into three steps, namely start, run and stop.

Startup: The following preparations should be done before startup:

(1) Check the integrity of the pump equipment.

(2) The bearing is filled with oil, the oil level is normal, and the oil quality is qualified

(3) Open all the inlet valves of the corrosion resistant submerged pump.

(4) Fill the pump with water or divert water from the vacuum pump (except for reverse irrigation) to open the vent valve to exhaust.

(5) Check the shaft seal for water leakage, and it is advisable to use a little dripping water for the packing seal.

(6) The direction of rotation of the motor is correct.

After the above preparations are completed, the motor can be started. After the speed is normal, check the pressure and current and pay attention to whether there is vibration and noise. After everything is normal, gradually open the outlet valve and adjust it to the required working condition. Note that the time of closing the valve and idling should not exceed 3 minutes.
