NicoyaVertical multistage centrifugal pipeline pumpToday’s market

　　After the submersible slurry pump leaves the factory, there is generally only outgoing cable, and the user needs to connect it separately during installation. If the connection is wrong, it will seriously affect the normal operation of the pump, so we should follow the correct steps to connect.　　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 choiceNicoya,　　 Packing shaft seal: the packing shaft seal is the most common seal, with simple structure, convenient maintenance and low price. However, the shaft seal water must be used. For the working conditions that are not suitable for the auxiliary impeller shaft seal, the packing shaft seal can be used.　　 When stopping the operation of the submersible slurry pump, close the cock of the vacuum gauge and pressure gauge and the gate valve on the water outlet pipeline, and After that, cut off the power supply of the motor. If the temperature of the environment is low, open the square plug at the lower part of the pump body to remove the remaining water to avoid frost cracking. During operation, the maximum temperature of the bearing shall not exceed ℃, and the quantity of calcium base grease used for lubricating oil bearing shall be the same as that of the bearing bodyLivani,　　 The working properties of the two pumps are also different. Because the sewage pump is driven by a motor, it generally has good voltage impact resistance. The submersible pump is of the type of quick opening and quick closing,NicoyaBaigang deep well pump, so it usually uses some small Flow and small pressure.　　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?　　Moreover, it is often troublesome to install it. Therefore,NicoyaScrew deep well pump, when it is used later, HH the types of slurry pump can be divided from the pump shell of slurry pump: single shell slurry pump and lecture slurry pump; Let&#;s talk more about the model classification of slurry pumps: such as ah, m slurry pumps. These series of slurry pumps can be collectively referred to as fractional series slurry pumps because these types　　In fact, the impeller clearance of submersible slurry pump is not adjustable for all types of pump, but it is adjustable. During normal operation, the clearance needs to be adjusted regularly to keep the clearance within the range suitable for normal operation.Convenient and efficient,NicoyaSubmersible non clogging slurry pump,　　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 addition　　Promote the continuous expansion of the sales network group.　　Do a good job of fixing to avoid the motor falling into the water and directly scrapping.

　　First, the reason for the motor body: the wrong connection will make the temperature rise rapidly when the equipment is used; In addition, there may be some phase to phase short circuits between stator windings, so when the situation is relatively minor, the motor is only in local placesWorkshop cost, 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.　　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　　 The working properties of the two pumps are also different. Because the sewage pump is driven by a motor, it generally has good voltage impact resistance. The submersible pump is of the type of quick opening and quick closing, so it usually uses some small Flow and small pressure.Nicoya　　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.　　 Then unscrew the nut at the front end of the pump shaft, remove the cover plate, and press out the middle impeller and water seal.　　First, the reason for the motor body: the wrong connection will make the temperature rise rapidly when the equipment is used; In addition, there may be some phase to phase short circuits between stator windings, so when the situation is relatively minor, the motor is only in local places
