Characteristics and applications of submersible pumps
Published:
Sep 19,2024
Submersible pump is a kind of equipment that sinks the pump equipment into the water and pumps the water to the ground or other places by means of the pump body and the motor. Submersible pump can not only be widely used in industrial production, agricultural irrigation and urban construction and other fields, but also has a high efficiency and stability. The following will discuss the working principle and performance characteristics of submersible pumps.
- The working principle of submersible pump
The working principle of the submersible pump is mainly to use the electric motor to drive the impeller to rotate, so that the water enters the pump, and then outputs the water through the pump body and the water outlet pipe. The submersible pump is placed in the water so that its inlet and outlet are both below the surface of the water. When the motor starts, the impeller starts to rotate, and the water is sucked into the pump and passes through the special design of the pump body, so that the water is subjected to the pressure generated, and then output through the water outlet pipe. The whole process is to rotate the mechanical parts of the pump through electric power transmission to achieve the purpose of pumping water from the lower layer to the upper layer.
- Performance characteristics of submersible pump
1.Small size and light weight: Because the submersible pump is installed vertically, it is small in size and light in weight, which is very convenient for transportation and installation.
2.Low noise and long service life: The motor of the submersible pump is integrated with the pump body, so its noise is low and its service life is long.
3.High pumping efficiency: The special design of the submersible pump body can improve the pumping efficiency and make the pump water output larger.
4.Corrosion resistance and wear resistance: submersible pumps are usually made of stainless steel, which has good corrosion resistance and wear resistance.
5.Automatic control: Submersible pumps are usually equipped with an automatic control system that can automatically control start-stop and water level.
6.Versatility: Submersible pumps can be used for different purposes, such as sewage, irrigation, water supply, etc.Multiple occasions.
3.Submersible pumps are also widely used, and some of the main areas are listed below:
•Wastewater: Submersible pumps are widely used in the gravel and wastewater industries. They are commonly used in pumping and lifting stations because they are compact and less expensive to install than other pumps.
•Sewage treatment: Sewage treatment requires submersible pumps, such as grinding pumps, which can transport solid materials from the inlet of the pump to the outlet without hindrance. These pumps typically remove sewage material to reduce contaminant particles for ease of handling and downstream processing.
•Suction pump: Submersible pumps are usually used to remove water that has accumulated in low-lying areas or can collect puddles. An example is the removal of tailings ponds from mining operations or the removal of water from the basement of a building due to flooding.
•Dredging: Port authorities use these pumps to dredge ports. They must be specifically designed to handle liquids with a high solids content.
•Water wells: Water wells and boreholes use these pumps to lift water to the surface. Widely used in the oil and gas industryESPSubmersible pumps lift oil from deep wells to the surface.
•Mining: Mine UseESPSubmersible pumps, which are designed differently from pumps used in the oil and gas industry. They had to cope with harsh conditions because the mine water was highly acidic with suspended solids.
•Oil and gas: Many submersible pumps in the oil and gas industry are based on electric submersible pumps(ESP)Principle operation. This is a cost-effective method of extracting large quantities of fluid from deep wells.ESPThe motors used in the system are designed to operate at high temperatures and pressures. They require special cables and are expensive.
