selection of flow: single suction pump or double suction pump shall be selected according to the flow; single suction pump or multi suction pump shall be selected according to the lift.　　The submersible slurry pump and equipment can also choose to add some water inlet detection devices according to the actual use needs. The overheat monitoring devices are often used in a large amount in time, and the pump and motor of the equipment used in time are the same shaft, soWhitnango,　　 Common faults and treatment methods of sewage pump due to different pump models,WhitnangoVertical centrifugal slurry pump, degrees of use and methods of use, there are also a variety of faults and problems. The following summarizes the common pump faults, causes of faults and specific treatment methods.　　If there are sundries blocked, the pump will not be filled with water. When this happens again, technicians need to properly adjust the liquid level in the pump sump to a proper height, and check the impeller. In case of damage or aging, it needs to be replaced in time,Larmani hat,　　Sex is different. Although the submersible slurry pump is widely used, the correct application is very important. Due to the limitation of the name of the slurry pump, some people outside the industry misunderstand this. In fact the impurity pump, dredging pump, desilting pump, etc. are all in the application scope of the slurry pump　　If the pressure in the local area is equal to or lower than the vaporization pressure corresponding to the water temperature in the flow process, the water will vaporize there and form many small bubbles mixed by steam and gas. The cavitation phenomenon is due to the bubble action when these small bubbles flow from the low-pressure area to the high-pressure area in the water pump,　　Schematic diagram of vertical slurry pump II. Why does the demand for submersible slurry pump increase greatly? From the perspective of market demand, it has a rapid development momentum, mainly due to the convenience and flexibility mentioned above; In addition, 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.　　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 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 damagedHonesty is the foundation,　　The submersible slurry pump is a kind of submersible pump which is connected with the motor and works underwater at the same time. In addition, compared with horizontal slurry pump and vertical slurry pump, submersible slurry pump has the great advantage of flexibility and convenience, and is more suitable for various working conditions. The important technical points of submersible slurry pump are its motor and　　 First remove the pump from the engine.　　 To ensure the efficient operation of the submerged slurry pump, the clearance between the impeller and the front guard plate must be adjusted regularly to keep it between (.-mm). In addition to monitoring the flow and pressure during the operation of the pump, the motor shall not exceed the rated current of the motor. Monitor oil seal and bearing at any time

　　 When starting the slurry pump, the outlet gate valve shall be (closed or slightly opened by /. Before starting the slurry pump,WhitnangoDeep well submersible pump, expand the pump inlet valve and close the pump outlet valve. Then start the pump. After the pump is started,　　Rate loss, so shaft power = effective power + lost power.　　Types of centrifugal pumps, etc.　　The purpose is to inject liquid higher than . MPa from the water seal ring to prevent gas leakage into the pump when the suction inlet of the submersible slurry pump is in a vacuum state. When the water pressure in the pump is higher than . MPa, the sealing fluid .-. MPa higher than the pressure in the pump can be injected to seal and reduce leakageWhitnango　　 Selection of pipeline diameter: the selection of pipeline shall consider the one-time purchase cost, long-term operation cost and operation reliability.　　If the pump outputs more medium liquid,WhitnangoCentrifugal slurry pump, it will certainly do more work. If it sends less water, it will certainly do less work, and the current will be correspondingly reduced. Pump power (kw) = head (m) × Flow (m/s) × The gravity of the fluid (kg/m for water) divided by (power conversion factor) divided by the efficiency of the pump (about　　Carbon, building materials, chemical industry and other industrial industries are mainly used to transport abrasive pastes containing solid particles.
