Sewage pumps, engineering professional manufacturer of submersible pumps, sewage submersible pumps Shandong coal pump, model complete, instructions for use, good quality specialty products plus / submersible sewage pump action: can sewage long fiber, bags, belts, grass, cloth and other substances tearing, cutting, then smooth emissions, particularly suitable for liquids containing hard solid, liquid fiber material and particularly dirty, sticky, slippery liquid. ?? AS, AV-diving sewage pump Chinese name ?? submersible sewage pump line ???? ?? Machinery Manufacturing Industry Overview Definition: submersible sewage pump is a pump and motor piece, and was working at the same time sneak pumps, today to introduce a new product. Sewage pumps, as the name implies, the sewage pump sewage pump is used, the advantages of the pump body, what is it? Listen Shandong coal Wang to introduce you oh: 1 advantage over the general horizontal or vertical pump sewage pumps, submersible sewage pump obviously has the advantage of the following aspects: 1. Compact, small footprint. Submersible sewage pump sump due to sneak into work, it can be directly installed in the sewage tanks, without the construction of pumping station dedicated to install the pump and machine, you can save a lot of land and infrastructure costs. 2. easy installation and maintenance. Small sewage pumps can be installed free, large sewage pumps are generally equipped with automatic coupling device can be automatically installed, installation and maintenance very easy. 3. continuous operation for a long time. Sewage pump since the pump and motor coaxial, short axis, rotating parts and light weight, so a relatively small bearing on the loads (radial), life is much longer than the average pump. The absence of cavitation damage and irrigation water and other issues. Especially after it brought a lot to the operator convenience. It is because of these advantages, submersible sewage pump has been more and more attention, more and more widely used range from the original simply used to transport water to be able to transport all kinds of domestic sewage, industrial waste, construction site drainage , liquid feed and so on. It plays an important role in municipal engineering, industrial, hospitals, buildings, hotels, water conservancy construction and other industries in. Some people say the sky is the sea upside down, you can still see its boundless. 2 R & D in order to improve the life of submersible sewage pumps, most domestic and foreign manufacturers are wanted on the pump protection system approach, which leak in the pump, capable of automatic alarm overload, over-temperature fault, and automatically shutdown equipment repair. But we believe that the protection system set up in the sewage pump is necessary, it can effectively protect the safe operation of the electric pump. But the key is not the problem, the protection system is only a remedy after a pump failure, is a more passive approach. The key question should proceed from the fundamental, completely solve the problem pump seal, overload, etc., this is a more proactive approach. To this end we expeller fluid power sealing technology and pump design technology used without overload submersible sewage pump, the pump seal greatly improved reliability and load capacity, extend the life of the pump. The so-called vice impeller fluid power sealing means installing an open impeller in the opposite direction near the back cover after the coaxial pump impeller. When the pump is working, deputy impeller rotates together with the pump shaft, expeller liquid will rotate together, the rotation of the liquid will produce an outward centrifugal force, the centrifugal force on the one hand against the flow of fluid mechanical seal, reduces the mechanical pressure seal at. On the other hand to prevent the media of solid particles into the mechanical seal friction, the reduction of the mechanical seal grinding block wear and prolong its service life. But deputy impeller sealing effect, but also may help reduce the axial force, the axial force composed mainly by fluid pressure differential force of gravity on the rotation of the impeller and the entire portion of the sewage pump, which the direction of action of the two forces are the same, they are added together is formed by two forces. It can be seen in exactly the same performance parameters, submersible sewage pump axial force than the average horizontal pumps to be large, while the balance of difficulty harder than the vertical pump. Therefore, sewage pumps, bearings easily damage their cause and axial force has a great relationship. If the installation Vice impeller, the liquid in the direction of the sub-wheel differential force is the force of the two opposite forces, which can offset part of the axial force, also played a role in extending bearing life. But with deputy impeller sealing system also has a drawback, that is in the sub impeller part of the energy is consumed, usually around 3%, but as long as the design is reasonable, can reduce this part of the loss to a minimum.

After looking at the teacher arrived hand, said: "So serious ah swollen?!" And then looked at the other hand, said: "! Oh, no swollen ah"
