Basic working principle of water pump
1.Working principle of centrifugal pump
There are many kinds of centrifugal pumps, but their working principles are the same and their structures are similar. Its main working parts are a rotating impeller and a fixed pump casing. The impeller is a component of a centrifugal pump that directly works on liquid. It has several backward curved blades, generally 4-8. When the centrifugal pump works, the impeller is driven by the motor to rotate at a high speed (1000~3000r/min), forcing the liquid between the blades to rotate accordingly. At the same time, due to the action of centrifugal force, the liquid moves radially from the center of the impeller to the outer edge. The liquid gains energy in the movement process of flowing through the impeller leaves the outer edge of the impeller at high speed and enters the volute pump housing. In the spiral case, due to the gradual expansion of the flow channel, it decelerates, converts part of the kinetic energy into static pressure energy, reaches a higher pressure, and finally flows into the extrusion pipe along the tangential direction.
When the liquid is forced to flow from the center of the impeller to the outer edge, a vacuum is formed at the center of the impeller. One end of the suction pipeline of the pump is connected with the center of the impeller, and the other end is immersed in the transmitted liquid. Under the pressure difference between the liquid level pressure (usually atmospheric pressure) and the pressure (negative pressure) in the pump, the liquid enters the pump through the suction pipeline. As long as the impeller keeps rotating, the centrifugal pump will constantly suck in and discharge the liquid. It can be seen that a centrifugal pump mainly relies on the centrifugal force generated by the high-speed rotating impeller to transport liquid, so it is called a centrifugal pump.
If the centrifugal pump is not filled with liquid before starting, there is air in the pump. Because the air density is very small, the centrifugal force generated is also very small. The vacuum formed at the suction port is not enough to suck the liquid into the pump. Although the centrifugal pump is started, it cannot deliver the liquid. This phenomenon is called "air binding". Therefore, before starting the centrifugal pump, the shell must be filled with liquid, and a bottom valve with a filter screen must be installed at the bottom of the suction pipe. The bottom valve is the check valve to prevent the liquid filled before starting from leaking from the pump. The filter screen prevents solid substances from entering the pump. The pressure-out pipe near the pump outlet is equipped with a regulating valve for regulating the flow.
2.Working principle of water ring vacuum pump
Vacuum refers to the gas state below the standard atmospheric pressure in a given space.
Machines or instruments that use mechanical, physical, chemical, or physicochemical methods to extract air from containers to obtain a vacuum are called vacuum pumps.
There are many kinds of vacuum pumps, which can be generally divided into three categories: Volumetric Vacuum pumps, jet vacuum pumps, and other types of vacuum pumps, of which Volumetric Vacuum pumps are the most widely used.
A water ring vacuum pump (referred to as a water ring pump for short) is a kind of coarse vacuum pump. The limit vacuum it can obtain is 2000~4000pa, and the series atmospheric ejector can reach 270~670pa. A water ring pump can also be used as a compressor, which is called a water ring compressor. It is a low-pressure compressor with a pressure range of 1~2 × 105Pa gauge pressure.
The water ring pump was initially used as a self-suction pump, and then gradually used in many industrial sectors such as petroleum, chemical industry, machinery, mining, light industry, medicine, and food. In many industrial processes, such as vacuum filtration, vacuum water diversion, vacuum feeding, vacuum evaporation, vacuum concentration, vacuum moisture regain, and vacuum degassing, water ring pumps are widely used. Due to the rapid development of vacuum application technology, water ring pump has been paid attention to in obtaining coarse vacuum. Because the gas compression in the water ring pump is isothermal, it can pump out flammable and explosive gases, as well as dust and water-containing gases. Therefore, the application of the water ring pumps is increasing.
Application field
① In the production of chemical and petroleum sectors, most of the raw materials, semi-finished products, and finished products are liquids, and the production of semi-finished and finished raw materials into semi-finished products and finished products needs to go through complex technological processes. During these processes, pumps play a role in transporting liquids and providing pressure flow for chemical reactions. In addition, in many installations, pumps are used to adjust the temperature.
② In agricultural production, pumps are the main irrigation and drainage machinery. my country's rural areas are vast, and a large number of pumps are needed in rural areas every year. Generally speaking, agricultural pumps account for more than half of the total output of pumps. Pumps are also the most used equipment in the mining and metallurgical industries. The mine needs to be drained by pumps, and in the process of beneficiation, smelting, and rolling, pumps are needed to supply water.
③ In the power sector, nuclear power plants need nuclear main pumps, secondary pumps, and tertiary pumps, and thermal power plants need a large number of boiler feed pumps, condensate pumps, oil and gas mixing pumps, circulating pumps, and ash pumps.
④ In national defense construction, the adjustment of aircraft flaps, tail rudders, and landing gear, the rotation of warships and tank turrets, and the ups and downs of submarines all require pumps. High pressure and radioactive liquid, and some also require the pump without any leakage.
⑤ In short, whether it is aircraft, rockets, tanks, submarines, drilling, mining, trains, ships, or everyday life, pumps are needed everywhere, and pumps are running everywhere. That's why the pump is listed as a general-purpose machine, which is a major product in the machinery industry.
⑥ Electric pumps i.e. pump driven by electricity. The electric pump is composed of a pump body, a water lift pipe, a pump base, a submersible motor (including cables), and a starting protection de
