The design principle of profile control pump is mainly based on hydraulic transmission. It first converts the high-speed rotating mechanical energy of the electric motor into hydraulic oil pressure energy through a constant power variable pump. Then, the pressure of these hydraulic oils can be directly converted into working pressure energy through the hydraulic cylinder, and this conversion process is achieved through the piston. This design gives profile control pumps various advantages, such as strong self suction ability, adaptability to various environments and usage scenarios, a wide range of pumping plugging agents, and suitability for all plugging agent materials used today.

In addition, the profile control pump can also be driven by an electric motor or diesel engine, and its prying form can meet the requirements of multiple construction projects in oilfield oil production plants. In industry, profile control pumps are mainly used to pump various viscous and non viscous liquids with weak corrosiveness, such as clean water, mud, water-soluble mixed liquids, etc. In addition to profile control operations, it can also be used for well cleaning, mud replacement, sand flushing and plugging removal, sandblasting and perforation, pipeline pressure testing and other operations. The profile control pump has become the equipment for middle note, water plugging, polymer injection and other process methods in secondary and tertiary oil recovery& Nbsp;

Overall, the design principle of profile control pumps is based on hydraulic transmission, which can effectively convert the mechanical energy of electric motors into working pressure energy, and has a wide range of applications and various advantages.
