Introduction to the regulation method of mine submersible pump

Mine submersible pump is mainly used in coal mine, mine submersible pump used in D type, DA type and TSW type multistage centrifugal pump; and the sump area and local drainage is commonly used type B and type Ba and BZ type single-stage centrifugal pump. With the increase in the scope of use of mine submersible pump, how to adjust the work, which is a lot of people this question, the next will be described in detail:
Introduction to the regulation method of mine submersible pump
Introduction to the regulation method of mine submersible pump
1, can be achieved through the throttle valve:

That is to change the open degree of the mine pump water outlet, the small gate valve, the local resistance of the pipe increases, the pipeline system characteristic curve becomes steep, the pump device's working point will make the corresponding change, the water quantity decreases accordingly. When the valve is closed, the local resistance of the pipe is close to infinity, and the water is cut off. The throttle adjustment method is simple and easy to operate, and is very used in production.
2, by changing the motor speed to change the operating point of the pump device:
Facts have proved that the new technology, new materials, new technology applications, not only the liberation of labor productivity, but also to ensure product quality and stable and reliable. Our country is a big agricultural country, submersible pump as an agricultural water to the irrigation tool into every household. The application of submersible pump in China's industrial field is also increasing. Submersible pump technology in China is still in the development stage, the technology should be further improved.
Speed control operation is refers to the mine submersible pump in variable speed motor drive operation, along with the coal mine problems in the processing of its outstanding performance, more people pay attention to the use of this product in the real production. How to maximize the performance of its use value, the need for manufacturers and customers to do more work and research, as long as the direction of development in the right direction, mine submersible pump will be more beautiful tomorrow.
