What is Hydraulic Gear Pumps?

February 02, 2024

1. Introduction The development and evolution of Hydraulic Gear Pumps
Hydraulic Gear Pumps are an important component used to transport hydraulic oil in hydraulic systems. Its principle is to use two or more gears that mesh with each other to generate a pressure difference through rotation, suck hydraulic oil from the low-pressure end, and then discharge it from the high-pressure end to realize the transportation and pressurization of hydraulic oil. Hydraulic gear pumps have the characteristics of simple structure, reliable operation, and easy maintenance. They are widely used in various hydraulic systems, such as engineering machinery, agricultural machinery, industrial machinery, etc.

The development history of hydraulic gear pumps can be traced back to the 18th century, when people began to use gear pumps to transport water and other liquids, such as cooling water for steam engines, extraction and transportation of oil, etc. With the development of hydraulic technology, people began to research and develop hydraulic gear pumps in the 19th century, and used gear pumps in hydraulic systems to drive various hydraulic equipment, such as hydraulic cylinders, hydraulic motors, hydraulic valves, etc. The design and manufacturing of hydraulic gear pumps have also been continuously improved, and various types and specifications of hydraulic gear pumps have emerged, such as external gear pumps, internal gear pumps, spiral gear pumps, spur gear pumps, etc., to meet different hydraulic requirements. system requirements.

The application scope of hydraulic gear pumps is also expanding with the advancement of hydraulic technology. In addition to the basic functions of hydraulic systems, such as transporting and pressurizing hydraulic oil, it can also be used for special functions of hydraulic systems, such as regulating flow and pressure. Implement variables and control functions. Hydraulic gear pumps can also be used in combination with other hydraulic components, such as hydraulic motors, hydraulic valves, hydraulic cylinders, etc., to form various hydraulic circuits and hydraulic devices to achieve various hydraulic actions and controls.

2. Basic knowledge
Hydraulic Gear Pumps are hydraulic components that use two or more intermeshing gears to generate a pressure difference through rotation, suck hydraulic oil from the low-pressure end, and then discharge it from the high-pressure end to realize the transmission and pressurization of hydraulic oil.

3. Advantages of the product
Hydraulic Gear Pumps have the following advantages compared to other types of hydraulic pumps:

The structure is simple, with only a few components such as gears, shafts, pump bodies, and pump covers. It has no complicated mechanical structure and is easy to manufacture and install.
The work is reliable, the gear meshing is automatic, no other control mechanism is needed, the work is stable, there is no jamming phenomenon, the life is long, and the failure rate is low.
It is easy to maintain, the gear wear is small, and there is no need to replace it frequently. It only needs regular inspection and cleaning, no disassembly and adjustment is required, and the maintenance cost is low.
The performance is good. The flow and pressure of the gear pump are proportional to the rotation speed. The flow and pressure can be adjusted by adjusting the rotation speed to realize variable and control functions to adapt to different working conditions.

4. Maintenance and maintenance
The maintenance and upkeep of Hydraulic Gear Pumps mainly includes the following aspects:

Regularly check the working status of the pump, and if there is any abnormality, troubleshoot in time.
Clean the inside of the pump regularly to remove impurities and dirt and keep the pump clean.
Regularly replace the pump sealing ring to prevent aging and damage and maintain the sealing performance of the pump.
Regularly lubricate the moving parts of the pump to reduce friction and wear and maintain pump flexibility.
Avoid pump overload and impact, and prevent pump deformation and damage.

5. Application areas
Hydraulic Gear Pumps have a wide range of applications, mainly including the following aspects:

Engineering machinery, such as excavators, bulldozers, cranes, etc., are used to drive various hydraulic actuators, such as hydraulic cylinders, hydraulic motors, hydraulic clamps, etc., to achieve various engineering operations, such as excavation, bulldozing, lifting, etc.
Agricultural machinery, such as tractors, harvesters, seeders, etc., are used to drive various agricultural equipment, such as hydraulic cylinders, hydraulic motors, hydraulic sprayers, etc., to achieve various agricultural operations, such as plowing, harvesting, sowing, etc.
Industrial machinery, such as injection molding machines, presses, plate rolling machines, etc., are used to drive various industrial equipment, such as hydraulic cylinders, hydraulic motors, hydraulic valves, etc., to achieve various industrial operations, such as injection molding, pressure, plate rolling, etc.
Other fields, such as aerospace, petrochemical industry, metallurgical mining, etc., are used to drive various special hydraulic equipment, such as hydraulic servo, hydraulic adjustment, hydraulic control, etc.
