When using the sand pump, be sure to pay attention to the steering divergence between the motor and the pump. The sand pump has an arrow on the pump to mark the main steering. After the power supply is connected, run the pump without load. Check whether the motor operates normally. During operation, be careful not to exceed the bearing on the pump support to avoid　　With water, you can start working.Chachuvapa,　　In recent years, domestic stainless steel pipeline pump products have greatly improved their technical level through introduction, absorption, renovation digestion and innovation, especially the supporting products of some major technical equipment have reached or approached the advanced level of similar products.　　Line direction pay attention to the direction of rotation. Then loosen the original compression nut of the bearing box of the slurry pump of the submersible pump, tighten the adjusting screw of the bearing box evenly and then move the rotor assembly towards the motor. Then it is necessary to check the clearance with a feeler gauge δ, When δ= A (. ~ mmAt Tall al Kabir,　　The use of water pumps is related to all aspects of our life. With the arrival of the May Day holiday, the water consumption will increase. Therefore, it is necessary for us to choose a suitable water pump.　　 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, and use the PID adjustment of the frequency converter. When　　The disc friction loss of the slurry pump impeller will decrease with the decrease of the impeller diameter, so that the pump efficiency of most low specific speed pumps will improve slightly after the impeller is cut. After cutting, keep the blades overlapped to a certain extent,ChachuvapaDeep well submersible pump, and the degree of blade overlap will decrease with the addition of specific speed

　　The high-efficiency slurry pump has three characteristics: first, the slurry pump has high operation efficiency and low loss.　　Static water level refers to the water level before the pump is started.　　 determination of model: for water pump or pump with physical and chemical medium similar to water it is necessary to go to the relevant product catalog or sample, and make correction according to the performance table or performance curve of the model to see whether the normal working point falls in the priority working area of the pump.supply,　　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　　The water pump can be used to transport and pressurize clean water without impurities, such as apartment, residence, villa water supply, factory water supply, water supply system, there are many uses.　　Head refers to the energy obtained from the pump by the unit weight of liquid output by the pump, so head refers to the effective energy obtained from the liquid output by the pump in unit time - that is, the effective power of the pump: the equation is PE= ρ GQH (W)= γ QH (W)

　　 Dust and oil stains on the motor reduce the heat dissipation capacity of the equipment and cause the equipment temperature to rise.offer,ChachuvapaVertical slurry pump,ChachuvapaSubmersible sewage pump,　　There is a difference between submersible slurry pump and sewage pump. Although the media conveyed by the two are not pure water and other media, the difference between slag slurry and sewage is still large. Let&#;s take a look at the difference between the two.　　And it shall be used according to the quota specified in the manual.　　How to avoid this situation when the equipment is in use.Chachuvapa,　　There is no need to equip auxiliary mixing or spraying equipment, and the operation is simpler. The equipment is directly submerged for operation, without noise and vibration, building materials, chemical industry and other industrial industries are mainly used to transport abrasive pastes containing solid particles.　　In order to ensure the demand for water and electricity for production and living, many units, 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
