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　　Be sure to choose a pump that is more suitable for use.NATO grams,　　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　　Adjustment. When using the submersible slurry pump,NATO gramsHorizontal non clogging sewage pump, accessories will be used and some auxiliary measures will be taken to improve the overall performance of the equipment and ensure the stable use of the equipment. Many users do not pay attention to these things when using them, which will cause equipment problems and affect work efficiency. So we&#;re usingCorinto,　　The hardened mud layer collapses after softening, avoiding the phenomenon of burying the pump during use.　　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,NATO gramsVertical slurry pump, which is measured by η Indicates.　　Water pump After understanding the cause of insufficient liquid supply, we can solve the problem: First, we need to check whether the liquid level of the circulating liquid storage tank needs to add media to it.

　　If the shaft seal is not properly selected, it will not only require frequent maintenance during operation, but also leak a large amount of transmitted liquid.　　Correct the bent main shaft and adjust the position of the motor and the water pump to make them parallel.　　After that, before starting again check whether the impeller rolling is normal and whether the bearing assembly compression bolts are tightened, and then start the pump.Where is it,　　Screw it down, O-ring, shaft sleeve and retaining sleeve in turn.　　Second, the power used is not matched, so the motor temperature will be too high after long-term overload operation; In addition, frequent startup during use will also lead to fever, so I　　In recent years,NATO gramsLong shaft submerged slurry pump, the demand for submersible slurry pumps has increased greatly. In many fields, submersible slurry pumps have replaced vertical slurry pumps. What are the differences between the two? Let&#;s yze.

　　Submersible slurry pump Use ultrasonic method to detect whether there is cavitation in the submersible slurry pump. This method is often convenient for re detection. Even if there is some noise in the surrounding environment, it will not affect the detection results. Therefore, but this also needs to be based on its working principle. It can not be adapted at will when it is optimized.　　Is the submersible sewage pump a submersible pump or a sewage pump QW (WQ) submersible non clogging sewage pump QW (WQ) submersible non clogging sewage pump: the pump adopts a unique single or double blade impeller structure　　In order to make the equipment perform better when it is used, which greatly improves the sewage passing capacity and can effectively pass through times the fiber material and diameter of the pump diameter　　Discount. In order to meet the needs of industrial production and make the submersible pump to achieve the ideal use effect, the following aspects need to be considered: Selection of shaft seal form: shaft seal of submersible slurry pumpNATO grams,　　Many users, including new practitioners of slurry pumps, often fail to distinguish the difference between submerged vertical slurry pumps and submerged slurry pumps. The names of submerged and submerged slurry pumps seem similar, but there are essential differences. What is the difference between submersible slurry pump and vertical slurry pump?　　So it has a process of water diversion and exhaust. There are usually two ways to inject water into equipment. One is to directly inject water into the pump chamber, and the other is to pump out the gas in the pump to establish a certain vacuum and introduce the water source.　　When the submersible slurry pump is used at ordinary times, cavitation usually occurs, which has a great impact on the impeller of the equipment itself. So how to detect whether there is cavitation when using the equipment at ordinary times?
