With water, you can start working.　　The non service life of the equipment is not as long as possible. If it is not used for a long time, it will not only easily corrode the parts, but also reduce the service life of the parts.Villa Nuva　　Stop the operation immediately under any of the following conditions: the current exceeds the rated value at the rated voltage; Under the rated head, the flow rate is much lower than that under normal conditions; Insulation resistance is lower than . megohm; When the dynamic water level drops to the pump suction; When the electrical equipment and circuit are out of specification　　Pump, sewage submersible pump and seawater submersible pump.Bati,　　 In addition, the use of ° and S-shaped bends should be reduced as much as possible during the installation and design of pipelines.　　 In addition, the use of ° and S-shaped bends should be reduced as much as possible during the installation and design of pipelines.　　 strip the outer layer of the cable to expose the copper wire for to mm, grind it to the oxide layer on the wire core, wipe the wire core with alcohol (or hydrochloric acid), wrap the insulation layer and sheath layer, and dry it naturally.

　　The use of water pumps is related to all aspects of our life. With the arrival of the May Day holiday, the water consumption will increase. Therefore, it is necessary for us to choose a suitable water pump.　　To help you solve the problem of removing the impeller of the slurry pump, we only need to fix the pump shaft and rotate the impeller in reverse to remove the impeller easily. For large pumps with impeller removal ring, we need to remove the impeller removal ring first, the water consumption will increase. Therefore　　The use of water pumps is related to all aspects of our life. With the arrival of the May Day holiday, it is necessary for us to choose a suitable water pump.　　Friction. Because if the surface of the pump is smooth when it is used,Villa NuvaBaigang deep well pump,Villa NuvaScrew deep well pump, the equipment will consume less energy when it is used. Generally, the submersible slurry pump and impeller are sprayed with polymer composite materials for use　　It is occasionally found that there is insufficient liquid supply when using, so what are the reasons for this situation and how to deal with it.

　　It is an auxiliary means of on-site monitoring. During the operation of the submersible slurry pump the condition of its overflow parts is very important to the overall operation. In order to let everyone know more about the equipment, we will learn how to adjust the impeller clearance of the pump in this issue. I hope it will help you.Information recommendation,　　; In practical application, the submersible slurry pump is developing rapidly with its unique advantages. The vertical slurry pump needs to be fixed and installed in use, while the submersible slurry pump can be used directly without immersion, which is convenient and flexible.　　 The failure to start the water pump may be caused by the power supply or the failure of the water pump itself.　　If the submersible slurry pump cannot be installed and operated, the blank operation point can be supplemented.Villa Nuva,　　However, there is also a disadvantage of using the auxiliary impeller sealing system, that is,Villa NuvaSmall deep well pump, it takes some energy on the auxiliary impeller of the submersible slurry pump, which is generally about %. However, as long as the planning is reasonable, metallurgy and coal　　It will burn out. If there is a heating problem in use, you can refer to the following reasons.　　Where ρ—— Density of transmission medium liquid (kg/m; γ—— Gravity of medium liquid (n/m; H -- pump lift (m); Q - water pump flow (m/s); G - gravitational acceleration (m/s.　　The difference between the shaft power P and the effective power PE is the power loss in the pump, which is measured by the pump efficiency. The pump efficiency is the ratio of the effective power and the shaft power, which is measured by η Indicates.
