What are the applications of automatic reciprocating cylinders in hydraulic high-pressure pumps?

I. Introduction

Nowadays, hydraulic systems are widely used in various mechanical equipment across different industries. As a transmission technology, the hydraulic method has the following advantages over the traditional mechanical method:

It can generate a great force and is easy to control.

2. It can achieve stepless speed change over a very wide range.

3. It is very easy to prevent overload and has high safety.

4. Small in size but high in output, and the installation position can be freely selected.

5. The control of output force is simple and accurate, and it can be remotely controlled.

Although the hydraulic system has the above advantages, the problem of its automatic reciprocation has never been effectively and reliably solved. In many industries and numerous devices, such as mud pumps in geological drilling equipment, high-pressure pumps in seawater desalination equipment, and fire pumps used in high-rise buildings, these devices require continuous output of high-pressure and high-flow fluid media. Due to the lack of a solution to the automatic reciprocating problem of the hydraulic system, traditional mechanical methods are still adopted, resulting in large equipment volume, high energy consumption, and low efficiency.

This project, "Hydraulic Automatic Reciprocating Cylinder", is a national utility model. It has successfully solved the problem of automatic reciprocation in hydraulic systems, making it possible for the above-mentioned equipment to adopt hydraulic technology. This technology involves a redesign of the main actuator in the hydraulic system - the cylinder, supplemented by an external control valve, to achieve the automatic reciprocation of the cylinder. It is reliable in operation, simple in structure and low in cost.

Ii. Application Scope

Hydraulic mud pump for geological drilling

The existing mud pumps use an electric motor to drive the crankshaft and connecting rod, pushing the piston to output mud. This structure has been in use for many years and is technologically backward. As a result, the mud pump is bulky, the output mud pressure fluctuates, the flow rate is unstable, and the maximum power of the mud pump is limited. Generally, the pressure can only reach 3 to 4Mpa, and the flow rate is not easy to be made very large. The hydraulic mud pump manufactured by applying this technology has a volume of only 1/2 to 1/3 of the existing mud pumps under the same output power, and its energy consumption is about 80% of that of the existing mud pumps. Although the manufacturing cost has slightly increased, the hydraulic mud pump has no power limit in its design. The output pressure can reach tens of Mpa, the flow rate can be infinitely expanded, and the output pressure and flow rate are stable. Wear-resistant electrode

2. Hydraulic high-pressure pump for seawater desalination

Reverse osmosis technology is a highly efficient and easy-to-use seawater desalination technology on a large scale. In today's water resource shortage, it has broad application prospects. The high-pressure pump is a key device in the application of reverse osmosis seawater desalination technology. The existing high-pressure pumps are basically of mechanical structure. The commonly used types of pumps are single-stage, high-speed centrifugal pumps, plunger pumps and multi-stage centrifugal pumps. Generally, single-stage centrifugal pumps have the lowest efficiency, while plunger pumps have the highest. In large systems, multi-stage centrifugal pumps are more commonly used. In China, there are no professional manufacturers of high-pressure pumps for seawater desalination yet. The main reason lies in the fact that to achieve a high efficiency of the high-pressure pump, it is necessary to ensure that some important components have very high processing accuracy, which requires very professional and expensive processing equipment as well as significant processing costs. Therefore, the price of imported high-pressure pumps is very high.

The hydraulic automatic reciprocating cylinder high-pressure pump has a significantly improved working efficiency compared with mechanical high-pressure pumps and plunger pumps, and it is easy to achieve high power. Compared with imported similar products, the greater the power of the pump, the lower the production cost, and the greater the decline in its price.

4. High-rise building water supply (fire pump)

In conclusion, the automatic reciprocating hydraulic system has broadened the application scope of hydraulic systems, enabling them to fully leverage their advantages of high efficiency, flexibility, high power, and low cost. Once applied, it will bring significant economic and social benefits to enterprises.
