The high-pressure plunger pump industry is developing rapidly. How can enterprises seize opportunities to achieve new breakthroughs?

The high-pressure plunger pump is the core component of the hydraulic equipment, which belongs to the positive displacement pump, and can achieve the purpose of conveying the liquid by means of the periodic change of the solvent in the working chamber. At present, high-pressure plunger pumps are widely used in pharmaceutical, food, chemical, petroleum, construction, shipbuilding, sugar, paper and other industries.

The author learned that the high-pressure plunger pump is also called the "heart" of the hydraulic system, and the hydraulic system is one of the key components of the equipment manufacturing industry. According to relevant statistics, 95% construction machinery, 90% CNC machining centers, and 95% and above automatic lines produced by developed countries all use hydraulic transmission technology. It can be said that any occasion with mechanical equipment is inseparable from the hydraulic system.

High-pressure plunger pumps have many characteristics, such as the instantaneous flow rate is pulsating. According to experts, this is because in the plunger pump, the suction and discharge process of the liquid medium is carried out alternately, and the speed of the piston is constantly changing during the displacement process. changing.

In a pump with only one working chamber, the instantaneous flow rate of the pump not only changes with time, but also is discontinuous. With the increase of the working chamber, the pulsation amplitude of the instantaneous flow becomes smaller and smaller, and it can even be regarded as turbulent flow in practice.

For example, it has strong adaptability to the conveying medium. It is reported that the plunger pump can transport any medium in principle, and is almost not limited by the physical and chemical properties of the medium. Of course, due to the limitations of the material and manufacturing process of the liquid end, as well as the sealing technology, sometimes there are situations that cannot be adapted.

Another example is good self-priming performance. The plunger pump not only has good suction performance, but also has good self-priming performance. Therefore, for most reciprocating pumps, it is usually not necessary to prime the pump before starting. Therefore, the machine has high efficiency and energy saving.

With the development of the times, some high-tech technologies have promoted the rapid development of the high-pressure plunger pump industry. Not only the functions of the equipment have been enhanced, but also the types have become more diversified to continuously meet customer needs.

For example, the main transport object of the traditional high-pressure plunger pump is a single water or other flowable liquid, gas or slurry, and the realizable high-pressure plunger pump has been able to handle some solid-liquid mixtures, gas-liquid mixtures, and solid-liquid-gas mixtures. , until live objects can be transported.

Some manufacturers said that the current high-pressure plunger pump industry has a good development space in the domestic market, and market competition is intensifying. If domestic enterprises want to seize opportunities and achieve breakthroughs, they still need to invest more energy.

Some experts said: "To achieve a technological breakthrough in high-pressure plunger pump products, we must first achieve a breakthrough in castings." , There is a certain gap between the control function of the variable mechanism and the dynamic and static performance indicators. These gaps are mainly manifested in product variety, performance and reliability, which will indirectly or directly lead to an increase in the failure rate of equipment.

In order to further promote the development of domestic high-pressure plunger pumps, some enterprises and regions have introduced international advanced technology, and also introduced hydraulic casting experts, quality control experts and software facilities, etc., realized the re-innovation of introduction and absorption, and achieved key Technological breakthrough.

Experts said: "Our independent products still need market testing and more user testing. In the initial stage, promotion and application is a difficult threshold. We call on relevant departments to provide policy support to help our independent products go to the market and replace imports. This in turn promotes the continuous improvement of the quality of our products.”
