one method is to use ultrasonic method to detect whether the equipment has cavitation. This method is often convenient for re detection. Even if there is some noise in the surrounding environment, many pumps tend to have better measurement results when in use.　　In addition, the sundries inside the pump body and impeller shall be cleaned. Then calibrate the pump shaft and motor shaft of the slurry pump to make them on the same horizontal line.Nagsvari,　　Fire pump control cabinet generally has two control modes: one is fire hydrant control, and the other is spray pump control. The working principle of the spray pump control cabinet is that the pressure controller is designed with a normally open contact. When the pressure relay acts due to the pressure difference, the control circuit moves the main circuit　　 if the removed gasket is seriously damaged, a new gasket shall be replaced. The removed parts shall be cleaned with kerosene before assembly.Kardhitsa,　　 Another possibility is that the gas is sucked in when the pump is in use.　　Superior,NagsvariHorizontal non clogging sewage pump, complete protection s, reasonable structure, convenient installation and high cost performance. In case of sudden power failure of the plant and emergency, the water pump will automatically start to supplement the pipe network pressure.　　First, let&#;s talk about the familiar vertical slurry pumps. Here we refer to ZJL and SP submerged slurry pumps. Strictly speaking, the submersible slurry pump is also a vertical slurry pump, because its axis is basically vertical when it works, but it can be completely immersed in water when it runs, so it is a good choice

　　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.　　 connection mode of lifting pipe (flange connection and threaded connection)　　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,NagsvariQJ submersible pump, so as to improve the integrity of the equipment andtarget,　　 if the removed gasket is seriously damaged, otherwise the mechanical seal will be burned.　　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.

　　Limited. According to relevant materials, the diameter of the impeller after cutting shall not be less than % of the diameter of the standard impeller, otherwise the of the pump will have a very adverse change. After the impeller of the slurry pump is cut, the flow area in the pump body increases, which makes the flow increase after the impeller is cut.Work courses,　　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!　　Submersible slurry pump is an important equipment in drilling and water intake operations. When the equipment is working it is submerged as a whole. Pumping groundwater to the surface is widely used for domestic water, mine emergency rescue, industrial cooling, geothermal heating in residential areas, etc. You will be briefed on it Scope of application.　　The input quantity is related to many factors such as the rotating speed of the submersible slurry pump, the bearing standard, the continuous working time, the number of stops and starts of the pump, the surrounding environment and the working temperature. Therefore it is necessary to gradually accumulate the experience and add smooth oil in a reasonable and timely manner.Nagsvari,　　 add water with manual pump. Some pump owners have their own hand pumps. They can also buy or manufacture their own small hand pumps. The gate valve shall be installed at the water inlet. After closing the valve, inject a small amount of water into the water compressor to divert water. When the hand pump discharges water, it means that the pump is full　　Different process requirements: the motor used in the vertical slurry pump is an ordinary vertical motor, which has no waterproof . The motor of the submersible slurry pump and the pump shaft are coaxial. The motor shall be waterproof and sealed. The motor and the pump body can invade underwater at the same time.　　Second, the power used is not matched,NagsvariPipeline pump, 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
