ZnoimoSmall deep well pumpWhat changes have taken place in the market

　　If the pump outputs more medium liquid, it will certainly do more work. If it sends less water, it will certainly do less work, which can be replaced without disassembling the slurry pump.Znoimo,　　 Pressure control: external electric contact pressure gauge or pressure controller can automatically turn on and off the pump according to the change of pipe network pressure. This type is widely used in domestic water supply and fire pressurization systems.　　Fourth, model selection parameters: outlet diameter, flow, dust,ZnoimoQJ submersible pump, motor power, impeller speed, pumping rate, maximum particle and weight.Mvomero, 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　　The type selection planning of submersible slurry pump has a great impact on its service life and operation stability. A scientific and reasonable type selection plan will affect whether the slurry pump can achieve efficient operation. The operating power of the slurry pump is very high and the loss is small. Service life of flow passage parts of pump　　The whole packing body, including the packing gland, packing ring and packing, needs to be disassembled; Submersible slurry pump Disassemble the o-seal ring, and then the discharge section includes the last stage guide vane

　　Head refers to the energy obtained from the pump by the unit weight of liquid output by the pump balance disc and key on the shaft in turn, 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)　　Note: Motors for special environment can be customized according to the contract.　　 First, screw down the bolts on the side bearing pressure cap, and then remove the nuts used for the connection between the three parts: discharge section, stuffing box body and bearing body; Then screw off the round nut on the shaft, and successively install the bearing inner race, bearing gland and retaining sleevequality standard,　　The first stage impeller of the pump is disassembled; It is also necessary to screw down the connecting nut between the water absorption section and the bearing body and the bolt on the bearing pressure connection so that it is convenient for us to disassemble the bearing parts; When the shaft is pulled out from the suction section, the fixing nut on the shaft shall be　　 Next, the water seal, lock ring and other parts need to be installed.　　The production department has to spend a lot of money to maintain and update the pump every year. The pumps made of cast iron,ZnoimoPipeline pump, rubber lining, stainless steel, titanium alloy and other materials used in China&#;s mining, chemical and water conservancy projects on the Yellow River are prone to wear, short service life and many faults

　　 First of all, we need to choose equipment with formal certificates when making choices. We must avoid buying some obsolete or inferior products. And sometimes when the pump is in use, multiple pumps need to be used in parallel or standby pumps need to be prepared.Bidding,　　There are differences.　　In terms of performance parameters, optional flow range: - (m/h), lift range: - (m), power range: .- (kw), caliber range: - (mm).　　The application of pumps involves all aspects of work and production, and the types of pumps are also diverse. Some of the same pump have several names, and some of the names are very similar, which makes it difficult to distinguish. Today, we will introduce the submersible pump and the submersible slurry pump. Is there any difference between the twoZnoimo　　Second, the power used is not matched,ZnoimoVortex pump and pipeline pump, so the motor temperature will be too high after long-term overload operation; In addition frequent startup during use will also lead to fever, so I　　 Move the sand pumping site frequently. When the pump pumps sand at a fixed position and drops to a certain height, lift the submersible slurry pump and move it to the adjacent position of the previous sand pumping place to continue pumping sand, so as to move the sand pumping place back and forth for sand pumping, so that the sand pumping area in this area forms a honeycomb,　　Will be scrapped. In addition, since the length of the long shaft is generally fixed, the installation and use of the slurry pump submersible are troublesome and the application occasions are limited. It is normal to use the equipment for a long time, for example, when the submersible slurry pump is used at ordinary times, air holes usually appear
