or the bottom valve is not closed tightly

　　Causes: there is air or gas accumulation in the water inlet pipe of the pump, the water supply is not satisfied, the packing of the vacuum pump leaks seriously, and the gate valve or flap valve is not closed tightly.　　The slurry pump should be larger. In addition to the existing industrial and mining applications of the vertical slurry pump, the submersible slurry pump can also be used as a mobile slurry pump, such as sand pumping and prospecting on board; What are the advantages of the submersible slurry pump? The advantage of the submersible slurry pump is that it is convenient and flexible easy to operate and submergedNanaimo,　　 Realize centralized management. In the application of multiple fire pumps, the deployment of fire pumps may be decentralized, and the working environment of fire pumps is often complex, so it is very difficult to adopt manual management. cf fire control cabinet can realize centralized management of multiple fire pumps, with operation　　No matter what type of slurry pump you need, Ritter pump will provide you with the highest quality slurry pump products; The latest development of submersible slurry pump technology in recent years The diving depth has increased from meters to meters!Sektevkar,　　The installation of submersible slurry pump is a step that needs to be concerned. Since we all care about it, it is mainly because the installation will directly affect the use effect. The installation work should be seamless. Some key operating points can be seen when installing the slurry pump.　　Cavitation of the pump is caused by water evaporation of the pump. The main cause of water evaporation is related to temperature and pressure. Under a certain pressure, when the temperature rises to a certain value, the water begins to vaporize and change from liquid to gas. On the contrary,NanaimoSmall deep well pump, at a certain temperature, the pressure drops to　　Pump, sewage submersible pump and seawater submersible pump.

　　 The submersible slurry pump usually relies on water cooling to dissipate heat. If the motor leaks out of the water without water cooling, the motor temperature will rise, so it is easy to burn out the motor.　　The discharge side of the pump must be equipped with a valve (ball valve or stop valve, etc.) and a check valve. The valve is used to regulate the operating point of the pump. The check valve can prevent the pump from reversing when the liquid flows back (the long shaft deep well pumps produced by our company are equipped with anti reversing check devices) and prevent the pump from being hit by water hammer　　If the submersible slurry pump cannot be installed and operated, the blank operation point can be supplemented.Good reputation,NanaimoHH slurry pump,　　If the oil seal ring of the shaft is seriously worn, replace it with a new one.　　If the water leakage is serious, the broken pipe shall be dismantled and replaced. Lower the lift and press the nozzle of the water pump into the water for .m.　　The above is a brief introduction to the effect and form of shaft seal of submersible slurry pump. Users can choose the appropriate shaft seal type according to their actual needs.

　　However, there is also a disadvantage of using the auxiliary impeller sealing system, that is, it takes some energy on the auxiliary impeller of the submersible slurry pump, which is generally about %. However, this part of the lost flow can be reduced. The slurry pump is mainly applicable to electric power, metallurgy and coalsystem,　　After understanding the working principle of the submersible slurry pump, we will also know that those parts are prone to wear during normal use. In this way, we can carry out targeted anti-corrosion and wear-resistant treatment on these parts during optimization, chemical industry, paper mills, timber, restaurants, textiles, bathrooms,NanaimoVertical multistage centrifugal pipeline pump, hotels and other departments. The operating temperature is generally not more than ℃.　　In this way,　　 Then replace the pulley and pump cover plate and tighten the fixing nuts.　　Fourth, model selection parameters: outlet diameter, flow, dust motor power, impeller speed, pumping rate, maximum particle and weight.　　The purpose is to avoid water leakage of the pump, but the water seal may be damaged due to faults after being used for a period of time. Let&#;s learn how to replace the water seal.
