The HG duplex pump is a hydraulic device widely used in industrial and construction fields. It features two independent pump bodies and can deliver different fluid media, such as oil, water, and emulsions, simultaneously or alternately. In industrial production, HG duplex pumps are extensively utilized in various hydraulic systems, including machine tools, forging presses, material handling equipment, and metallurgical machinery, providing stable and efficient hydraulic power for these machines.

The internal gear pump is a common hydraulic component primarily used for transferring liquid media. In an internal gear pump, the plain key shaft is a crucial component mainly used to secure the gears and transmit power. Below is a detailed explanation of the plain key shaft in internal gear pumps:

The internal gear pump is a common hydraulic component whose development trends are primarily driven by technological advancements, market demands, and environmental regulations. Below is a detailed analysis of these development trends:

A duplex internal gear pump is a widely used device in the field of hydraulic transmission, characterized by high pressure, high efficiency, and low noise. When selecting a duplex internal gear pump, the following factors should be considered: I. Model Selection Displacement and Pressure Rating: Choose the appropriate displacement and pressure rating based on actual requirements.

A blow molding machine is a mechanical device used to produce plastic products such as bottles, caps, and containers. Its primary function is to transform plastic raw materials into various shapes and sizes of plastic products through processes including heating, plasticization, stretching, and blow molding. The manufacturing process of a blow molding machine involves mechanical machining, electrical commissioning, assembly, and installation. The following is a detailed introduction to this manufacturing process.

Both duplex internal gear pumps and standard internal gear pumps have their own advantages and disadvantages, and the specific choice depends on the application scenario and requirements. Advantages of Duplex Internal Gear Pumps: Compact structure with small dimensions and weight.

An internal gear pump is a common hydraulic component widely used in various types of mechanical equipment. However, due to limitations in its operating principles and material properties, its service life is often restricted. To extend the service life of internal gear pumps, the following methods can be adopted: I. Rational Selection and Use of Lubricants

The performance curves of an internal gear pump describe the relationship between the pump's performance and parameters such as pressure, flow rate, and rotational speed. These curves help us understand the pump's operating characteristics, performance, and application scope. Below, using HG0/HG1/HG2 internal gear pumps as examples, we will explain in detail the meaning and reading methods of these performance curves.
