How To Use Submersible Pumps Correctly And In A Standardized Manner?

　　Subliquid pump is a new generation pump product successfully developed based on the introduction of technology and combined with the use characteristics of domestic pumps.It has the characteristics of energy saving, spinning, non-blocking, automatic installation, automatic control, etc.It is also a special type of centrifugal pump, which has a wide range of applications in industrial production. Let’s take a look at its usage specifications.Precautions for maintaining safety: 1. Strictly implement process operating procedures and various safety systems.2. Do not reverse the operation.3. Do not cut off the fluid.4. Pumps with cooling water must not be cut off from running.5. If there is leakage and looseness during operation, the car must be stopped to deal with it.Precautions for maintenance safety: 1. Before maintenance, go through the equipment that is allowed to undergo maintenance.2. Before the equipment is repaired, cut off the power supply and hang the \"No mobile sign\" sign before repairing.3. For any fire operation at the production site, apply for a \"fire certificate\".4. The maintenance tools and parts for disassembly and cleaning should be arranged neatly and civilized construction should be carried out.5. When entering pits or underwells for maintenance, hazardous gas and oxygen content should be analyzed to avoid poisoning.Safety precautions for test drive: 1. There must be someone instructing the test drive of the liquid pump.2. Set up obvious test run signs and prohibit unrelated personnel from entering the test run site.3. After the test run is completed, the operator closes the valve and stops the operation according to the parking procedure, and notifies the electrical department to cut off the power.Notes on usage: 1. Cannot start.Check whether the wiring connection is firm and whether the switch contact is tight.If the circuit is open or the contact is poor, calibration should be performed.2. The motor is overheated.Check whether the wiring and switch are short-circuited, check whether the impeller, impeller cover and motor stator conflict with the rotor, and clear obstacles in time.3. Lack of liquidity.This is because the elevator is too high, the pipes are too long, and the pipes are bent at right angles.Adjust the head, shorten the pipe, change the curvature of the pipe, check and clean the filter and pipe blockage.4. Can't absorb water.The reason is that air and water supply pipes accumulate in the pump body.Cleaning method: First increase the water pressure, inject water into the pump body, turn on the power supply, check the oil seal ring of the pump shaft, and replace the new product when the wear is severe.The above is related to the sub-liquid pump.
