The working principle of the multi-stage centrifugal pump for mining is the same as that of the ground centrifugal pump. When the motor drives the impeller on the shaft to rotate at high speed, the liquid filled in the impeller will be thrown to the impeller from the center of the impeller along the flow path between the blades under the action of centrifugal force. Because the liquid is affected by the blades, the pressure and speed increase at the same time, and it is guided to the next-stage impeller through the flow passage of the guide shell. In this way, it flows through all the impellers and the guide shell one by one to further make the liquid Pressure energy increases. After stacking each impeller step by step, a certain head is obtained and the downhole liquid is lifted to the surface. This is the working principle of the stainless steel multi-stage pump.

China Petroleum & Chemical Corporation purchased a batch of special pumps for construction sites from our company, including high-viscosity heavy oil internal gear pumps, stainless steel gear pumps, special additives pumps, special stainless steel high-viscosity glue pumps, stainless steel heat preservation gear pumps, etc., ready to load and ship.

Asphalt pump is a popular and widely used positive displacement pump. It is specially used to transport asphalt. People are habitually called asphalt pump. At present, there are several types of pumps in the market that can be used to transport asphalt. Hebei Shenghui Pump Industry Co., Ltd. will analyze it for everyone.

After the YCB arc gear oil pump is used for a period of time, the gear will gradually wear out during the continuous rotation process, resulting in a decrease in flow rate and a decrease in delivery pressure. In order to achieve the initial conditions of use, it is necessary to replace a new oil pump or The oil pump is being repaired. The technicians of Hebei Shenghui Pump Industry are here to talk about several key points of the repair.

The double screw pump is a positive displacement pump with active screw meshing. There are many structural forms. Today, let's talk about the characteristics of the oilfield two screw pump.

Internal gear pumps are also called high-viscosity pumps or high-viscosity gear pumps. They are different from ordinary external gear pump gears. The internal gear pump consists of an outer rotor, which is separated and fixed by a crescent plate and a pin. The rotor, the inner and outer rotors run in the same direction, and they are relatively stable after running, with low noise and no pulsation. Especially suitable for conveying highly viscous materials.
