Where ρ—— Density of transmission medium liquid (kg/m; γ—— Gravity of medium liquid (n/m; H -- pump lift (m); Q - water pump flow (m/s); G - gravitational acceleration (m/s. The difference between the shaft power P and the effective power PE is the power loss in the pump, which is measured by the pump efficiency. The pump efficiency is the ratio of the effective power and the shaft power,FushkrugerSelf priming non clogging sewage pump, which is measured by η Indicates. Cutting blades can be selected to cut some large block solid substances into pieces during use, so that blockage can be avoided during reuse.Fushkruger, Submersible slurry pump is an important equipment in drilling and water intake operations. When the equipment is working, it is submerged as a whole. Pumping groundwater to the surface is widely used for domestic water, mine emergency rescue, industrial cooling, geothermal heating in residential areas, etc. You will be briefed on it Scope of application. Second, the service life of the flow passage parts of the pump is relatively long, saving production costs.Lampang, Yes, such mechanical faults will cause the stator winding of the pump to be burnt out. 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 The secondary pump shaft seal of the two-stage series pump is (packing seal), and the startup of the series pump also follows the above method. Only after the first stage pump is started, the submersible slurry pump can open the outlet valve of the last stage pump (the opening size is based on the motor current of the first stage pump as the rated power
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) Select an appropriate flow according to the water inflow of the well or pool or the water consumption required by the actual engineering system. During model selection, the flow shall be close to the model flow grade of the sample (to ensure that the pump operates in the high efficiency zone). In fact, the pumps I am going to talk about here have a wide range of uses. Pumps are required for both civil and military purposes, as well as for advanced technologies,FushkrugerSmall deep well pump, chemical, metallurgical and other industrial sectors. It is a widely used general mechanical equipment. Most pumps are corroded or severely corrodedmarket, 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, 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 (. ~ mm When the slurry pump fails to absorb water during operation, it may also be because the bottom valve is not opened. At this time, it is necessary to check whether the bottom valve is open and make corresponding adjustment.
The two have certain commonalities. They are both submersible. As the name suggests, the pump is in an invasive state when running. The submersible slurry pump is a kind of submersible pump but generally speaking, people often say that the submersible pump refers to the clean water pump, such as the submersible pump for domestic water and farmland irrigation and pumpingSampling inspection, Wheel, mixing impeller and other main flow passage parts are made of high wear-resistant raw materials, which are wear-resistant corrosion-resistant, non clogging and have strong sewage discharge capacity, and can effectively pass through large solid particles. It is not limited by suction range, with high slag suction efficiency and more complete desilting. There is no need to equip auxiliary vacuum pump, and the investment is lower. Vertical pipeline centrifugal pump is a kind of pipeline centrifugal pump with vertical structure. There are many models of this pump. The common one is ISG pipeline centrifugal pump. This pump is also very widely used. It is often used in industrial and urban water supply and drainage, The above is the reason for the insufficient liquid supply of the water pump when it is in use, as well as the specific methods to deal with this situation. We should pay attention to the regular inspection of the equipment during normal use to ensure that it is in use During the process, the equipment must be regularly maintained and overhauled to avoid blockage. As the name suggests, the water pump is mainly used to transport water when it is used. The effect of normal pumps is often better when it is used, but in fact, we use it at ordinary times Submersible pump is a common water lifting equipment for deep wells. During operation, the whole machine intrudes into the water to extract water from the underground to the surface. It is commonly used for domestic water, mine rescue, industrial cooling,FushkrugerSewage pump diving, farmland irrigation, seawater lifting ship load adjustment, landscape fountains, etc. Submersible pump is generally divided into clean water submersible
