Introduction to the application of submersible pump

Submersible pump is a mechanical and electrical integration of high-tech products. In recent years, because of the submersible pump has made great progress in sealing, insulation, cooling and monitoring technology, but also successfully realized the automatic coupling of water pump and a water outlet pipe, so that the large diameter submersible pump application significantly faster. As the submersible pump station in saving investment, can quickly install and repair, operating conditions greatly improved, the reliability and service life of the equipment is significantly improved. At present, our country not only production and installation of large diameter 900mm under axial flow pump and mixed flow pump, also can produce large diameter 1.4m and 1.6m submersible electric pump, for submersible electric pump station to promote the technology to lay a good foundation. The submersible pump is not afraid of flooding, but also has quick removal and installation flexibility is good, able to cope with the water level soared, pump house flooded and other emergencies, large submersible pumps come out, make the pump structure, installation and operation environment changed revolutionary. Compared with the conventional pumping station, the advantages of submersible pump station in low-lying areas are more obvious. At the same time, and the submersible sewage pump and pump sediment and other pump types, can clear the drainage channel.
Advantages of submersible pump application
1 pump station is not afraid of flooding
In low-lying areas, the dike burst or coming torrential rain over the design standard, irrigation and drainage pumping station is often flooded. Once the pump station mechanical and electrical equipment is soaked in water, cleaning and baking and other repair work is very heavy, will delay the drainage time, increase disaster losses. Therefore, the conventional pumping station itself is also a very important problem of flood prevention and control of the problem. But the submersible electric pump is a submersible motor, pump unit can be run under the water. Therefore, even if the pumping station was flooded, as long as the motor is not overloaded, the pump can work in the stable area of submersible electric pump can be put into operation at any time. 2 unit assembly and disassembly fast
The submersible pump and the water outlet pipe is connected by bolts, mainly for pumping water, drainage and other small construction. But between the submersible pump and the water outlet pipe in modern times has achieved the automatic coupling in the outlet pipe is fixed, does not need the bolt can be fast installation and removal of the pump unit, thus greatly accelerating the speed of installation and maintenance unit. The main installation types of submersible electric pump are mobile and guide rail coupling two.
3 save pump station project investment
Pumping station project investment including civil investment and equipment investment. After the use of submersible electric pump, construction investment and equipment investment can be reduced.
(1) construction investment. Due to the following reasons, the construction investment of submersible pump station is 30% ~ 50% than that of conventional pumping station.
The submersible pump unit can run in the water, not afraid of wind and rain, the upper structure can save water;
The coaxial pump submersible pump, small axial size, lifting pump height is small, even if the need to build the superstructure, its height is lower than the conventional pumping station;
The need for standby unit pumping station, only spare submersible pump unit, without increasing the standby unit position, which can reduce the length of the pumping station;
The submersible pump does not need a water supply pump, drainage pump, vacuum pump, fan and other auxiliary equipment, hydraulic pump small size, simple structure.
(2) equipment investment. Due to the sealing, insulation, cooling and other requirements of the submersible pump, a variety of monitoring equipment in the unit is also more, so the cost of the submersible pump itself is usually higher than the conventional unit. But because the submersible pump can save a lot of auxiliary equipment, submersible pump station equipment investment is still below the conventional pumping station.
4 high reliability and long service life
Compared with conventional submersible pumps and pumping equipment, auxiliary equipment, submersible pump, it can not only simplify the operation procedure, is conducive to automation, and can greatly reduce the probability of failure, thus significantly improve the reliability of equipment. At the same time, because of the recent development of sealing, insulation, cooling and other technologies, the submersible pump is not prone to failure. Even if the seal leakage, temperature rise is too high, insulation decline and other phenomena, a variety of sensors will be in time to the signal, and control and protection, therefore, the submersible pump with high reliability.
In addition, the installation and disassembly of submersible pump is very convenient, in the non operation season can be lifted, greatly improving the unit management conditions, thereby prolonging the service life of long pump unit.
