High -pressure hydraulic pump

High -pressure hydraulic pump- This is a device that transforms mechanical energy into hydraulic energy of liquid under high pressure. It is widely used in various industries, including construction, mechanical engineering, aviation and agriculture. In this article, we will consider the principles of work, types, criteria for choosing and using high -pressure hydraulic pumps to help you make a conscious choice.

What is high -pressure hydraulic pump?

High -pressure hydraulic pumpIt is the heart of any hydraulic system, providing the necessary pressure for the operation of actuators, such as hydraulic cylinders and hydraulic models. It is designed to create high fluid pressure, which is used to transfer energy and work. The pump converts mechanical energy (for example, from the engine) into hydraulic energy (fluid stream under pressure). The company LLC International Mongolia Zhitsyan construction equipment specializes in the supply of high -quality hydraulic equipment.

The principle of operation of a high -pressure hydraulic pump

The principle of workhigh -pressure hydraulic pumpBased on the creation of the difference in pressure. The pump takes the liquid from the tank and moves it to the system, creating high pressure. There are various types of pumps, each of which has its own mechanism for creating pressure, but the general idea is to reduce the volume of the working chamber, which leads to fluid displacement.

Types of high -pressure hydraulic pumps

There are several main typeshigh pressure hydraulic pumps, each of which has its advantages and disadvantages:

Gear pumps

Six -up pumps are one of the simplest and most common typeshigh pressure hydraulic pumps. They consist of two gears rotating in the case. The liquid is captured between the teeth of the gears and is transferred from the entrance to the exit. Sixth pumps are reliable, inexpensive and easy to maintain, but have a relatively low efficiency and performance. On the sitenmgrq.ruYou will find a wide selection of gear pumps.

Plastic pumps

Bad pumps use a rotor with radial grooves in which the plates slide. When rotating the rotor, the plate is moved and moved, creating a changing volume that pumps the liquid. Plastic pumps provide higher performance and efficiency than gear, but more sensitive to fluid pollution.

Piston pumps

Piston pumps are the most productive and reliable typeshigh pressure hydraulic pumps. They use pistons moving in cylinders to pump fluid. Piston pumps can create very high pressure and provide high flow control accuracy. However, they are more complex and expensive to maintain than other types of pumps.

High pressure hydraulic selection criteria

The choice is suitablehigh -pressure hydraulic pumpDepends on several factors, including:

• Required pressure:Determine the maximum pressure necessary for the operation of your hydraulic system.
• Performance:Calculate the required volume of fluid flow in liters per minute (l/min).
• Type of liquid:Consider the type of hydraulic fluid used in the system. Some pumps are incompatible with certain types of liquids.
• Terms of Use:Take into account the conditions in which the pump will work, such as temperature, humidity and the presence of pollution.
• Budget:Install the budget for the purchase and maintenance of the pump.

Field of use of high -pressure hydraulic pumps

High pressure hydraulic pumpsWidely used in various industries:

• Construction:Excavators, bulldozers, cranes and other construction equipment.
• Mechanical engineering:Hydraulic presses, CNC machines and other industrial equipment.
• Aviation:Flight control systems, chassis and other aircraft equipment.
• Agriculture:Tractors, combines and other agricultural equipment.
• Mining industry:Board installations, excavators and other mining equipment.

Technical characteristics and examples

Consider examples of technical characteristics of various typeshigh pressure hydraulic pumps:

Data source: General data on the types of pumps, the actual characteristics depend on the specific model and manufacturer.

Maintenance and repair of high -pressure hydraulic pumps

Regular maintenance and timely repairhigh pressure hydraulic pumpsIt is necessary to ensure their reliable and durable work. It is recommended to observe the following measures:

• Regular oil replacement:Use only the oil recommended by the manufacturer.
• Checking check:Timely eliminate any fluid leaks.
• Filters cleaning:Clean or replace the filters regularly.
• Examination check:Periodically check the pump for the presence of signs of wear.

Conclusion

High -pressure hydraulic pumpIt is an important component of many hydraulic systems. The correct choice and maintenance of the pump provides reliable and efficient operation of the equipment. Consider all the factors, including the required pressure, performance, type of liquid and operating conditions, to make a conscious choice.
