In this way, a smooth surface can be formed on the surface.　　The of descending axial force can be used for slurry transportation in power plants, hydraulic and other professions; The mechanical seal is tight and reliable and the leakage probability does not exceed drops /min, which is mostly used to transport flammable, explosive, toxic, strong corrosive and valuable liquids or materials with high temperature, high pressure and low temperature.Assad ā b ā d　　Slide evenly and slowly along the guide rail until the active coupling is in place. When the mobile device is selected, the hose shall be sleeved first, and the chain rope shall be threaded into the two lifting rings to lift the electric pump up and down. Be careful not to use the cable as a rope to avoid danger.　　 Before starting the submersible slurry pump, the rotor of the rotating pump shall be smooth and even, the outlet sluice valve shall be closed, and water shall be injected into the pump to ensure that the pump is full of water without air.Menemeni,　　 First of all,Assad ā b ā dSubmersible pump can pump sewage, resulting in poor heat dissipation effect.　　Limited. According to relevant materials multiple pumps need to be used in parallel or standby pumps need to be prepared.　　 It is also possible that the fan blades of the pump are few and the air volume is insufficient, 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.

　　In fact, 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, the flow is smalldevice management,Assad ā b ā dIrrigation deep well 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.　　After meters, the sealing of the equipment can not bear the water pressure at this depth.　　The above is the reason for the insufficient liquid supply of the water pump when it is in use, as well as the specific methods to deal with this situation. We should pay attention to the regular inspection of the equipment during normal use to ensure that it is in use

　　.Respect for customers,　　 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　　The fire control cabinet adopts centralized management and one key operation. The startup procedure is simple and convenient. It can control multiple fire pumps at the same time, greatly providing work efficiency.　　Friction. Because if the surface of the pump is smooth when it is used, the equipment will consume less energy when it is used. Generally, the submersible slurry pump and impeller are sprayed with polymer composite materials for useAssad ā b ā d,　　Do not exceed the rated current.　　Carbon, building materials, chemical industry and other industrial industries are mainly used to transport abrasive pastes containing solid particles.　　It will burn out. If there is a heating problem in use, you can refer to the following reasons.
