Modern society is a society that emphasizes efficiency and benefits. The industrial industry pays more attention to the development of new technologies to improve the efficiency of industrial machinery. Generally speaking, there are many factors that will reduce the efficiency of sanitary pumps . For example , the operating conditions of the centrifugal pump are lower than the rated conditions of the pump, the pump efficiency is low, and the energy consumption is high; or the motor efficiency remains basically unchanged during use . And hydraulic loss includes hydraulic friction and local resistance loss. Compared with the mechanical sanitary pump , the new negative pressure pump has greatly improved working efficiency. It broadens the scope of application of hydraulic systems, making the hydraulic system more efficient, flexible, high-power, and low-cost advantages. After the application, it will bring huge economic and social benefits to the enterprise. Compared with imported similar products, lower finished products are the main factor in its occupation of the market. Sanitary pump is a general-purpose mechanical product with large consumption and wide application. The market demand for this product accounts for about 80% of the total demand for pump products. Therefore, the energy saving and consumption reduction of sanitary pumps are of great significance. Usually the method to reduce the energy consumption of sanitary pumps is mainly the application of frequency conversion energy-saving technology. Strictly follow the sanitary pump operating rules. Before starting the pump, you must perform the disc pump, open the inlet valve, close the outlet valve, perform exhaust and vent, and check the pump inlet Whether the pressure meets the requirements. Prevent cavitation of the pump caused by low supply pressure and insufficient flow. Or check the pump efficiency of sanitary pumps regularly, and find out the reasons in time for pump sets with low pump efficiency and take corresponding measures to solve them. And now it has undergone restructuring of a new type of sanitary pump. The new type of sanitary pump has a large flow, high discharge pressure, wide performance, high efficiency, long life, and high reliability. The product replaces the traditional high-efficiency and high-efficiency water injection pump equipment. Low sanitary pump water injection equipment has important practical significance for reducing oil production costs in oil fields.
