It may be that the motor power of the water pump is too large, the working current is too large, and the heat generation is too large resulting in the high temperature of the vacuum pump.　　 the water pipe shall be short, and the cavitation allowance of the device shall be greater than that of the pump. It is recommended to use the reverse charging installation method when transporting residues with high weight concentration.Metapan ,　　 observation method: people can visually observe whether the machine parts on the submersible slurry pump are loose, cracked and damaged. Through comprehensive ysis of various observation information, we can judge whether the pump has fault, fault location, fault degree and fault cause.　　 install a valve to inject water at the water inlet and outlet. This method is to install a valve on the water inlet pipe of the submersible slurry pump and connect the water pipe to inject water into the pump. This is a common and simple method.Benin,Metapan Rubber lining submerged slurry pump,　　Stop, then tighten the bearing seat, press down the nut, and fix the axial position of the rotor. The latter submersible slurry pump uses a barrel support, if there is a problem with the clearance in the future use, loosen the support clamp first, and say that the nut is loose　　After that, the secondary and tertiary pumps can be started successively until the final stage pump. After all the series pumps are started, the outlet valve of the final stage pump can be gradually opened. The speed of opening the valve should be controlled by the fact that the pump does not vibrate and the motor of any stage does not exceed the rated current.　　Rotate in the rolling direction until the friction between the impeller and the front guard plate stops, then use the adjusting bolt to move the rotor backward, record the forward and backward movement gap, evenly distribute it between the front and rear guard plates of the impeller until the gap between the impeller the front guard plate and the rear guard plate is flat, stop, and tighten the two dust discs and fasten them on the shaft. adjustment

　　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　　Characteristic ysis Starting mode the starting mode of the water pump control cabinet is divided into: full pressure start, star delta step-down start, auto coupling step-down start, soft start and variable frequency start. Proper starting mode shall be selected according to power supply conditions and other factors.　　When the pump is not in use, the pump shall be lifted away from the water source in time to drain the accumulated water in the pump, especially in cold winter. Then put it in a dry place. Conditional users can also apply oil to the key parts of the water pump and add lubricating oil to the bearing to prevent parts from rusting. in additionreform,　　It can improve the mechanical efficiency to a certain extent. Moreover, the molecular structure of the coating itself has good compactness which can well isolate the air, water and other media from the pump impeller during use, and also reduce the corrosion and rust as much as possible　　 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　　 there is also a simple method to measure the vibration frequency of the pump by vibration method. However,Metapan Small deep well pump,Metapan Vertical heavy-duty slurry pump, when using one method, there may be some errors in the measurement results. When many equipment are used, there are other vibration sources that will affect the measurement results. Therefore, in fact, at least in recent years, the situation of power shortage will continue and China&#;s economic growth trend will maintain a high speed. Therefore, especiallyproject,　　What is the order.　　 Mechanical seal: mechanical seal is generally used when the sealing requirements are relatively high, especially in the chemical industry. It is not only required that the slurry should not leak, but also not allowed to enter the pump body. The disadvantage of mechanical seal is high cost and difficult maintenance.　　 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, it will not affect the detection results. Therefore, many pumps tend to have better measurement results when in use.Metapan ,　When using the submersible slurry pump, the equipment may be burned out. The main reason for this phenomenon is improper operation. How should we prevent the burning out?　　 there is also a simple method to measure the vibration frequency of the pump by vibration method. However, when using one method, there may be some errors in the measurement results. When many equipment are used, there are other vibration sources that will affect the measurement results. Therefore, in fact, it is mainly　　According to the user&#;s requirements, the motor can add a variety of protection devices such as water inflow detection and overheating, so that the product can operate safely for a long time under adverse working conditions.
