The industry of high-pressure plunger pumps is experiencing rapid growth. How can companies seize this opportunity to achieve new breakthroughs?

The high pressure piston pump is the core element of hydraulic equipment, and it is a volumetric pump that can achieve the purpose of transporting liquids by the periodic change of solvent in the working cavity. At present, high pressure cylinder pumps are widely used in pharmaceutical, food, chemical, petroleum, construction, shipbuilding, sugar, paper and other industries.

The author learned that the high pressure piston pump is also called the "heart" of the hydraulic system, which is one of the key components of the equipment manufacturing industry. According to relevant statistics, 95% of the construction machinery produced in developed countries, 90% of the numerical control processing centers, and more than 95% of automatic lines have hydraulic transmission technology. It can be said that whenever there are mechanical equipment, there is no need for hydraulic systems.

High-pressure cylinder pumps have many characteristics, such as the instantaneous flow is pulsed, experts explained that this is because in a cylinder pump, the induction and removal of the liquid medium are alternated, and the speed of the piston is constantly changing during displacement.

In a pump with only one working cavity, the instantaneous flow of the pump not only changes over time, but is not continuous. With the increase of working cavities, the pulsing amplitude of transient flow is becoming smaller and can even be considered practically turbulent.

For example, it has strong adaptability for delivery media. It is reported that a socket pump can in principle convey any medium, almost unconstrained by the physical and chemical properties of the medium. Of course, due to the limitations of the materials and manufacturing processes of the liquid end and the sealing technology, there are sometimes unadaptable situations.

Furthermore, for example, there is good self-sucking performance, and the piston pump not only has good suction performance, but also has good self-suction performance. Therefore, for most reciprocating pumps, there is usually no need to fill the pump before starting. Therefore, the machine is highly efficient and energy efficient.

With the development of the times, some high-tech technologies have promoted the rapid development of the high-pressure cylinder pump industry, not only enhanced the function of the equipment, but also more diversified, continuously meeting the needs of customers.

For example, the main transport object of a traditional high pressure socket pump is a single water or other liquid that can flow, Gas or plasma, and the realizable high pressure piston pump has been able to convey some solid-liquid mixtures, liquid-liquid mixture, solid-liquid gas mixture until a living object can be conveyed.

Some manufacturers said that at present, the high pressure cylinder pump industry has good development space in the domestic market, market competition is intensifying, and domestic enterprises need to invest more energy if they want to seize the opportunities and achieve breakthroughs.

Some experts said: "To achieve technological breakthroughs in high pressure piston pump products, we must first achieve a breakthrough in castings." Compared with foreign brands, domestically produced hydraulic piston pumps have a certain gap in technical advancedness, working reliability, service life, variable body control function and motion and static performance indicators. These gaps are mainly in product variety, performance and reliability, which indirectly or directly lead to an increase in equipment failure rate.

In order to further promote the development of domestic high-pressure cylinder pumps, some enterprises and regions have introduced international advanced process technology, and also introduced hydraulic casting experts, quality control experts, and software facilities, which have realized the introduction and absorption of re-innovation, and have achieved breakthroughs in key technologies.

Experts say:“Our autonomous products also need market inspection and more user inspection. In the initial phase, promoting the application is a difficult threshold. We call on relevant departments to give policy support to help our independent products go to market, replace imports, and in turn promote the continuous improvement of the quality of our products.”
