St. CatherineLong shaft submerged slurry pump,

　　The supply of shaft seal water must be ensured. It is strictly prohibited to operate without water, otherwise the mechanical seal will be burned.　　For example, concentrate and tailings are treated in the concentrator, ash and slag are removed from the power plant, slime and dense medium coal are transported in the coal preparation plant, and slurry is transported in coastal river mining operations. The weight concentration of the treated slurry is: mortar %, ore slurry %; It can be operated in series according to the needs of users.St. Catherine,　　 Determine the head h. After the flow is determined, determine the inlet and outlet pipe diameters of the pump complete the layout of the whole pipeline, and determine the head. In the actual selection, the resistance coefficient of the pipeline is often too large. In addition, when selecting the pump model, a head margin is added, resulting in　　After a certain value, water will also vaporize, which is called the vaporization pressure of water at this temperature.Botsani,　　Is called cavitation phenomenon.　　 We also need to make choices according to local conditions when we make purchases at ordinary times. For example, the head of the centrifugal pump itself is relatively high, but its water output is not very large when it is used, so it is effective when it is used in many mountainous areas　　Stability and reliability of seals between pump bodies.

　　 If it is found that the impeller is damaged and the liquid supply is insufficient,St. CatherineUsed pipeline pump, it is necessary to replace the new impeller in time for use.　　Ensure that the power supply voltage is adjusted to the standard power supply to solve the problem.　　 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 damagedproperty right,　　The high-pressure water flows to the space occupied by the original bubble at a very high speed, forming an impact force. The metal surface of the pump was fatigued and damaged by these impacts. Cavitation is caused by air bubble rupture and material stamping due to the difference in air temperature and pressure　　 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 damaged　　In order to ensure the demand for water and electricity for production and living, many units,St. CatherineFire deep well pump, hotels and residential areas in various provinces and cities in China have purchased it and generators. Many enterprises have also purchased generators out of their own pockets in order not to delay production. Driven by this, it and the generator naturally become popular

　　The submersible slurry pump shall be shut down for inspection in time in case of machine problems during operation and regular maintenance shall be done. The equipment will not be used after burning out, which will cause certain economic losses to us.Let's see,　　Its main features are as follows: the whole machine is a dry-type motor pump structure. The motor is protected by mechanical seal, which can effectively prevent high-pressure water and impurities from entering the motor cavity. In addition to the main impeller, it is also equipped with a mixing impeller, which can pump out the slag settled at the bottom after stirring into turbulence. impeller　　In fact, stainless steel is not only advocated in the medical industry, but also widely used in the water pump industry. The stainless steel submersible pump of denang pump is one of them.　　 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, the motor will not work normally, resulting in damage to the submersible slurry pump. The biggest difference between the submersible slurry pump and the horizontal slurry pump and the vertical slurry pump is that the motor of the submersible slurry pump and the shaft connected to the pump are integrated and sealed Closed.　　Submersible slurry pumps generally need to use some composite materials for manufacturing when they are used, so that they can have good wear and corrosion resistance when they are used, swelling and deformation, insufficient spring pressure, breakage, etc.
