Application of centrifugal pump industrial engineering
(1) Solid particle liquid transportation
In industrial engineering, the fluid machinery with liquid to transport solid particles is called solid-liquid two-phase flow pump, also known as the impurities centrifugal pump. Mud pump, power station ash removal slag pump and river dredging dredging pump, widely used in gold, petrochemical, food and other industries and sewage treatment, port river dredging and other operations. In recent 10 years, mining, energy industry, the rapid development of solid pipeline transportation technology, the demand for impurities pump is increasing. At the same time, driven by modern science and technology, the impurity pump tends to develop in the direction of high life, high efficiency and many varieties.
① Cyclone pump. Swirl pumps (or eddy current pumps, that is, impeller retraction pumps) are suitable for the use of the highest non-clogging requirements, such as the pumping of food (fish, fruit, vegetables, etc.), and increasingly common for the pumping of sewage and other solid-liquid mixtures.
(2) pump. Lifting pump is a vertical multistage segmented centrifugal pump. It is mainly used for vertical shaft excavation to absorb and discharge muddy water containing a small amount of silt and small particles, and can also be used as the drainage of submerged mines. It is commonly used drainage equipment for coal, gold, mines and national defense underground projects.
③ Vertical centrifugal sand pump without shaft seal. Vertical centrifugal sand pump without shaft seal is a kind of high efficiency, low consumption, energy saving new impurity pump, it breaks through the current domestic impurity pump structure form, mainly used for conveying two phase fluid containing solid suspended particles, such as concentrate, tailings, sand and gravel mixture slurry, the effect of conveying foam slurry is better.
(2) the application of centrifugal pump in petroleum and chemical industry
Centrifugal pump in the petroleum industry
Electric submersible high pressure diesel pump is a widely used rodless pumping equipment, the motor and centrifugal pump together down the well and connected with the tubing, the motor is connected with the ground power supply through the cable, its downhole unit is composed of multistage centrifugal pump, protector and submersible motor. Electric submersible centrifugal pump is especially suitable for large displacement pumping of oil Wells in the middle and late stage of oilfield water injection development.
Petrochemical and chemical process centrifugal pump
In petrochemical and chemical industry process, centrifugal pump is the most commonly used fluid machinery.
A) High speed centrifugal pump. High speed centrifugal pump has been widely used in oil refining, petrochemical and chemical industry due to its advantages of high single-stage head, compact structure, convenient maintenance, good reliability and wide range of application. The high speed of the high speed centrifugal pump is generally driven by the motor and gear drive growth mechanism and the corresponding lubrication and monitoring system.
Can also be used to transport gasoline, diesel and other flammable and explosive media, usually in chemical plants, oil stations as a diesel pump to use.
