High pressure plunger pump is the core component of hydraulic equipment, belonging to the positive displacement pump. It can achieve the purpose of conveying liquid through the periodic changes of solvent in the working chamber. At present, high-pressure plunger pumps are widely used in industries such as pharmaceuticals, food, chemicals, petroleum, construction, shipbuilding, sugar making, and papermaking.

I understand that high-pressure piston pumps are also known as the "heart" of hydraulic systems, and hydraulic systems are one of the key components in the equipment manufacturing industry. According to relevant data statistics, 95% of engineering machinery, 90% of CNC machining centers, and more than 95% of automatic lines produced in developed countries use hydraulic transmission technology. It can be said that in any situation where mechanical equipment is present, the hydraulic system is indispensable.

There are many characteristics of high-pressure plunger pumps, such as the pulsating instantaneous flow rate. Experts explain that this is because in plunger pumps, the suction and discharge processes of liquid media are alternating, and the piston's speed is constantly changing during displacement.

In a pump with only one working chamber, the instantaneous flow rate of the pump not only varies with time, but also is discontinuous. As the working chamber increases, the fluctuation amplitude of instantaneous flow becomes smaller and smaller, and can even be considered turbulent in practice.

For example, it has strong adaptability to conveying media. It is reported that plunger pumps can in principle transport any medium, almost without being limited by the physical and chemical properties of the medium. Of course, due to the limitations of the material and manufacturing process of the hydraulic end, as well as the sealing technology, there may also be situations that cannot be adapted.

For example, with good self priming performance, plunger pumps not only have good suction performance, but also have good self priming performance. Therefore, for most reciprocating pumps, it is usually not necessary to fill the pump before starting. Therefore, the machine is highly efficient and energy-saving.

With the development of the times, some high-tech technologies have led to the rapid development of the high-pressure piston pump industry, which not only enhances the functions of equipment, but also diversifies the types to continuously meet customer needs.

For example, the main transportation object of traditional high-pressure piston pumps is a single water or other liquid, gas, or slurry that can flow, while high-pressure piston pumps can already transport some solid-liquid mixtures, gas-liquid mixtures, solid-liquid gas mixtures, and even live objects.

Some manufacturers have stated that the high-pressure piston pump industry currently has good development space in the domestic market, and market competition is constantly intensifying. Domestic enterprises need to invest more energy to seize opportunities and achieve breakthroughs.

Some experts said: "To achieve the technical breakthrough of high-pressure plunger pump products, the first thing is to achieve the breakthrough of castings." Compared with foreign brands, domestic hydraulic plunger pumps have a certain gap in technical progressiveness, working reliability, service life, variable mechanism control function and dynamic and static performance indicators. These differences are mainly manifested in product variety, performance, and reliability, which can indirectly or directly lead to an increase in equipment failure rate.

In order to further promote the development of domestically produced high-pressure piston pumps, some enterprises and regions have introduced international advanced process technology, as well as hydraulic casting experts, quality control experts, and software facilities, achieving re innovation through introduction and absorption, and achieving breakthroughs in key technologies.

Experts say, "Our independent products still need market testing and more user testing. In the initial stage, promoting applications is a difficult threshold. We call on relevant departments to provide policy support to help our independent products enter the market, replace imports, and in turn, promote the continuous improvement of our product quality.
