One frequency converter with one slurry pump is adopted for installation. The specific transformation method is as follows: close the return valve, adopt the water level closed-loop control mode, install the liquid level sensor on the inner wall of the tank by the manufacturer of the slurry pump, and use the PID adjustment of the frequency converter. When　　Second, the service life of the flow passage parts of the pump is relatively long, saving production costs.Yerevan,　　 Professional maintenance: if the submersible sewage pump cannot work normally, do not disassemble and repair it without authorization but carry out professional maintenance immediately.　　The submersible slurry pump is a slurry pump which is connected with the motor and works under the water at the same time. Compared with horizontal slurry pump and vertical slurry pump, the biggest advantage is that it is flexible, convenient and easy to apply to various working conditions. The most important technical point of submersible slurry pump is the tightness between its motor and pump body Stability and reliability of seals.Hvidovre,　　Rate.　　 When stopping the operation of the submersible slurry pump close the cock of the vacuum gauge and pressure gauge and the gate valve on the water outlet pipeline,YerevanBooster pipeline pump, and After that, open the square plug at the lower part of the pump body to remove the remaining water to avoid frost cracking. During operation, the maximum temperature of the bearing shall not exceed ℃, it is necessary to prevent damage to flow passage components caused by water hammer.

　　It is not correct that it has no effect on us.　　 Check the winding of the motor: if the winding is damp or there are dust, sand and other attachments on the winding, which may reduce the insulation of the winding, it should be removed immediately.　　The pump can often be selected according to the specific requirements of lift, flow and liquid delivery. The flow range of the delivered liquid is - L / s, the pressure range is .- MPa, and the diesel engine speed range is - rpm. Features: water pump, high automation and performanceWelcome calls ,　　In fact, it can only be opened or closed,YerevanWear resistant slurry pump, and the action time when opening and closing is relatively short.　　 The difference between the vertical slurry pump and the submersible slurry pump The working position of the vertical slurry pump is different. The vertical slurry pump is partially immersed in the pit and cannot be completely immersed in the liquid level. The submersible slurry pump can be completely immersed (including the motor part) below the liquid level; Use of motor for vertical slurry pump　　 If there is abnormal sound inside the slurry pump and there is no water, it is likely that the equipment may have air infiltrating into it when absorbing water, which will cause abnormal sound inside the pump, and then at the same time, the impeller is damaged or the impeller is damaged

　　Most of the time, we don&#;t know how to choose the pump when we buy it. In fact, we only need to choose the appropriate equipment according to our own use needs when we choose it. It&#;s more like that in a conventional family, when we use it,　　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.　　 The casing ground wire of the electric pump shall be connected in strict accordance with relevant regulations. When the electric pump is running, it is strictly prohibited to work or move in the water of nearby devices or people, in case of accidents caused by the power distribution of the electric pump.　　 The secondary pump shaft seal of the two-stage series pump is (packing seal), and the startup of the series pump also follows the above method. Only after the first stage pump is started, the submersible slurry pump can open the outlet valve of the last stage pump (the opening size is based on the motor current of the first stage pump as the rated powerYerevan,　　In the application of pumps, the first thing we think of is water. Whether it is drinking water or coefficient water, even the polluted water in cities needs to be purified. All these require its equipment to provide services for us. Without pumps, our basic survival is a problem.　　With the continuous development of slurry pump technology,YerevanSubmersible slurry pump, submersible slurry pump appears in response to market demand. It is especially suitable for the depth at which the vertical slurry pump cannot operate. The underwater part of the vertical slurry pump is generally not more than m, and of course it can be more than. For example the maximum design depth of our company&#;s underwater slurry pump can reach m, but such underwater depth is not the best operating depth of this kind of pump, so it will lead to the unreliability of the operation of the vertical slurry pump from time to time.　　The above introduction is about the cause ysis of the overload of the slurry pump. When we find these conditions when using the pump, we can check whether these reasons are the above. This is also a reminder that we need to maintain the pump during normal use. latent
