Centrifugal pumps are widely used in various types of hydraulic machinery, and they are the most familiar machines in our daily life and production activities.
Second, industrial engineering
(1) Solid particle liquid transport In industrial engineering, a fluid machine for transporting solid particles with a liquid is called a solid-liquid two-phase flow pump, also called an impurity pump. Impurity pump is a pump product suitable for conveying solid objects of various shapes, such as tailings pumps for mine conveying tailings, mud pumps used in coal washing plants, ash slag pumps for power station ash removal, and dredging pumps for river dredging, etc. Widely used in metallurgy, petrochemical, food and other industries and sewage treatment, port river dredging and other operations. In the past 10 years, in the mining and energy industries, solid material pipeline transportation technology has developed rapidly, and the demand for impurity pumps has increased. At the same time, under the impetus of modern science and technology, impurity pumps tend to develop in the direction of high longevity, high efficiency, and variety. At present, there are three types of impurity pumps that are mainly used in various industries in the world: centrifugal pumps, isolation pumps, and diaphragm pumps. Centrifugal impurity pumps account for the vast majority. Centrifugal impurity pump is divided into sewage pump, gear pump, mud pump, sand pump, dredging pump and gravel pump according to different purposes. There are also several special centrifugal impurity pumps,
The pump features:
1) No packing seals and other shaft seals, no pressure water shaft seals are required, the medium being conveyed will not be diluted. There is no frequent maintenance and power loss due to wear of the shaft seal device;
2) The material inlet is open vertically upwards, no gas blocking and cavitation will occur during the operation, and the suitable working flow will frequently change within a large range, and it can run idly;
3) The backlash between the impeller and the cover can be adjusted externally;
4) Simple structure, reliable operation and convenient maintenance.
(II) Petroleum and Chemical Industry
1 Centrifugal pumps in the oil industry
The electric submersible centrifugal pump is a kind of rodless oil pumping equipment which is widely used. The electric motor and the centrifugal pump are connected downhole and connected to the oil pipeline. The motor is connected to the ground power through the cable. Its downhole unit is protected by multi-stage centrifugal pump. And submersible motors. The electric submersible centrifugal pump is particularly suitable for large-displacement pumping of oil wells in the middle and later stages of oilfield water injection development. With the continuous deepening of oil wells, the oil and gas content in oil wells is gradually reduced. In order to fully exploit them further, water injection and chemical injections should be made in wells. High-power high-pressure and large-flow centrifugal pumps (multi-stage centrifugal pumps or high-speed centrifugal pumps) are the key equipment for water injection.
After oil and gas are pumped to the ground, they are collected and metered together at the oil-gathering station. After oil and gas are initially separated, they are sent to the joint station for heating and separation, dewatering, and stable crude oil. After the sewage passes through settlement and filtration, the natural gas passes through the light oil and is dehydrated. Later, it will become four qualified products of crude oil, natural gas, purified water and light oil, and then the separated crude oil and natural gas will be sent directly to refineries or pipelines to various users. Centrifugal pump plays the role of transporting liquid in the process of gathering and transportation, and it is indispensable for gathering and transportation.
