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　　When the submersible slurry pump works, the pump needs to be placed on land,Lespinasse Pipeline pump, the suction pipe needs to be placed in water and the pump needs to be started. Due to special structural requirements, when the slurry pump motor is submerged in the water, the slurry pump and submerged slurry circulating pump need to be placed above the water surface, so they need to be fixed, otherwise the motor will fall into the waterLespinasse ,　　 Use a V insulation resistance meter to measure the insulation resistance between phases and phase to ground of the electric pump motor, the motor stator winding shall be dried,Lespinasse Wear resistant slurry pump, and the drying temperature shall not exceed ℃.　　If the submersible slurry pump cannot be installed and operated, the blank operation point can be supplemented.San-Vicente,　　Yes, summer is the peak sales season. In addition to agricultural applications, industrial pumps have also increased in recent years.　　The motor is scrapped. Moreover, the installation and use of the pump is troublesome, and the application occasions are subject to many restrictions.　　 We must choose to consider the actual use situation when making the selection, because there will be some difference between the marked head when using and the head when using. This is because the pipe itself

　　 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　　Work to prevent the electric pump from overheating and damage. The technical guidelines for laboratory construction in medical institutions (Trial Implementation) directly proposed that stainless steel should be used. Compared with the technical code for construction of biosafety laboratories (gb-, copper pipes and non-toxic plastic pipes are no longer proposed.　　 During the installation of smooth bearing components, if the installation is correct, the smooth oil is appropriate, the repair is timely, and the delivery life will be long, the repair personnel should regularly repair the bearing components, check the condition of the bearings and the smooth oil, and regularly add or replace the smooth oil during the work,Lespinasse Deep well submersible pump, and the interval and writeQuality risk,　　Stability and reliability of seals between pump bodies.　　Discount. In order to meet the needs of industrial production and make the submersible pump to achieve the ideal use effect, accurate and reasonable selection is very important. In order to select the pump reasonably and correctly, the following aspects need to be considered: Selection of shaft seal form: shaft seal of submersible slurry pump　　It will burn out. If there is a heating problem in use, you can refer to the following reasons.

　　 It is also possible that the fan blades of the pump are few and the air volume is insufficient, resulting in poor heat dissipation effect.Bidding,　　The pump should be divided into two aspects: electricity and machinery. As for machinery, you can compare the previous maintenance records. The second is electricity. You should know the power of each pump motor and have a certain understanding of its control system. Slurry pump with mechanical seal　　The main and feature of self-priming pump is self-priming capacity. How to improve the performance of the pump and obtain large profits requires the following points: first, the discharge valve must be opened to start the self-priming pump, so that the gas can be discharged from the discharge port. Secondly, there should be enough liquid in the cavity of the self-priming pump, otherwise it will not　　The operating environment is different: the key difference between the submersible slurry pump and the vertical slurry pump lies in diving. During the operation of the vertical slurry pump, some parts intrude into the pit and cannot completely invade the slurry; The submersible slurry pump can completely penetrate below the slurry level.Lespinasse ,　　In fact, when the submersible slurry pump is blocked during use, it will not only have a certain impact on the working efficiency of the equipment during operation, but also cause serious damage to the equipment itself so it is also a reminder that we are using it too　　 The gas inadvertently entered in the equipment is discharged and good sealing performance is ensured.　　 If the pump is equipped with a vacuum gauge or pressure gauge, close the cock connected with the submersible slurry pump before starting the motor, and then gradually open the outlet sluice valve. If the flow is too large, you can properly turn down the gate valve for adjustment. Otherwise, if the flow is too small,Open the gate valve.
