KawaguchiSmall deep well pumpThe price rebound in late October is still expected

　　 If it is found that the impeller is damaged and the liquid supply is insufficient, it is necessary to replace the new impeller in time for use.　　This phenomenon shows that the failure of the pump is not only a material problem, but also reminds the pump designers and producers that in addition to good working conditions, the pump should also have good corrosion resistance, high reliability and long service life. The pump shall be designed in addition to the conventional design method of fluid mechanicsKawaguchi,　　There is no suction line. As the water storage tank is not deep enough and the suction pipe of the water pump is not deep enough, the inlet pipe of the water vortex is not deep enough. Water with a lot of gas. Destroy all normal water Self-priming pumps. To ensure sufficient depth of digestion and absorption of low watermark water. At that time, the depth was .~lm, and it was impossible to　　Submersible slurry pump can be widely used in mining, power, metallurgy, coal, environmental protection and other industries to transport abrasive slurry containing solid particles. Such as ore slurry transportation in metallurgical concentrator, hydraulic ash removal in thermal power plant,KawaguchiVertical multistage centrifugal pipeline pump, coal slurry and heavy medium transportation in coal washing plant, river dredging, river dredging, etc. In chemical industryOliveira do Douro,　　 Prepare tools and materials: a set of metric box / open-end wrench, bearing puller (commonly known as triangle puller), magnetic dial indicator, outside micrometer, caliper, square ruler, copper bar, hammer, V-shaped irons of the same specification, clean kerosene, oil basin, cotton yarn,KawaguchiCarbon steel explosion-proof pipeline pump, etc.　　Friction resistance due to bearing and packing; Friction between impeller and water during rotation; The vortex of water flow in the pump, inlet and outlet impact and other reasons. A part of the power must be consumed, so it is impossible for the water pump to completely change the power input by the power machine into effective power, in which the constant active power　　Many users, including new practitioners of slurry pumps, often fail to distinguish the difference between submerged vertical slurry pumps and submerged slurry pumps. The names of submerged and submerged slurry pumps seem similar, but there are essential differences. What is the difference between submersible slurry pump and vertical slurry pump?

　　Reasonable.　　QW (WQ) non clogging submersible sewage pump QW (WQ) non clogging submersible sewage pump IV. the submersible sewage pump uses V power supply which should be three-phase power supply. If the submersible pump has only two-phase power supply, it will not start. In this case, a professional electrician should be asked to use a clamp on ammeter or a submersible pump control　　When the submersible slurry pump works the pump needs to be placed on land, 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 waterInspection environment,　　Under the action of auxiliary devices, it can transport the slurry and because the sealing device itself is special, it can also ensure the internal and external balance of the submersible slurry pump during transportation, so that the pressure at both ends of the equipment can be balanced during normal use　　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.　　During adjustment, firstly loosen the support cover, then compress the nut, and then loosen the bearing seat. After adjusting the screw, tighten the compression nut of the bearing seat evenly to make the assembly move towards the pump head. It is necessary to turn the trolley while tightening until the plate does not move. Rotate according to the pump operation

　　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.How much is it,　　 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.　　This series of slurry pumps are self-developed slurry pump products in China, with simple structure, belonging to medium and light slurry pumps; ZGB series slurry pump, this series of slurry pump is a heavy-duty slurry pump, which can be used in series; When SP and ZJL series work, some pump bodies can　　 Impeller protection in order to ensure the operation of the submersible slurry pump, it is necessary to timely adjust the clearance between the impeller and the front guard plate. When adjusting the impeller clearance, first stop the pump, loosen the bolts pressing the bearing box, loosen the adjusting nuts, make the bearing components move forward, and roll the shaft by hand to press theKawaguchi,　　If the pump outputs more medium liquid, it will certainly do more work. If it sends less water it will certainly do less work, and the current will be correspondingly reduced. Pump power (kw) = head (m) × Flow (m/s) × The gravity of the fluid (kg/m for water) divided by (power conversion factor) divided by the efficiency of the pump (about　　Pump. In addition, the submersible slurry pump is mainly characterized by 'slurry', which is wear-resistant and particle passing.　　The submersible slurry pump is developed to adapt to the increasingly complex working conditions and facilitate the use of users. Its use mode is more flexible. The equipment has advanced structure, strong sewage discharge capacity,KawaguchiZD slurry pump, excellent material selection and strong corrosion resistance. Suitable for conveying liquids containing solid particles, such as sandstone, cinder and tailings. So what are the requirements for its work? Let&#;s understand briefly.
