What is a Hydraulic Pump? Structure and Operating Principle of Hydraulic Pump

A hydraulic pump is an important device in the hydraulic system, a device used to create pressure in the hydraulic system to bring hydraulic fluid from the tank into the pipeline and push it through valves or pistons. To better understand hydraulic pumps, learn with Truong Linh Parts through the article below.

1. What is a hydraulic pump?

Hydraulic pumps are an important component in the hydraulic system, used to create high pressure in hydraulic fluid (usually hydraulic oil) to perform tasks such as lifting, pushing, pulling and controlling. hydraulic devices such as hydraulic cylinders and hydraulic motors.

Hydraulic pumps are often used in fields such as manufacturing industry, construction, agriculture, automobiles, and many other applications. They play an important role in providing pressure and control in hydraulic systems, helping to perform mechanical work, improving performance and ensuring safety during the working process of machinery and equipment. bag.

Normally, pumps have a variety of working pressure levels, can be set at 700 bar or 10,000 Psi, can be installed in many different positions such as on the oil tank... Hydraulic oil pumps provide oil for single cylinders and also for Dual cylinders with diverse strokes and diameters.

2. Structure and operating principle of hydraulic pump

2.1. Hydraulic pump structure

Hydraulic pumps come in many different types, and will have different structures to suit the system. Below is a description of the construction of a hydraulic pump:

Hydraulic Pump Structure:

Pump casing: is the outermost component of the pump, it surrounds and protects the pump's internal components. Pump casings are often made from high quality metals to ensure heat resistance, durability and corrosion resistance during operation.

Hydraulic pump housings can be made from metals such as stainless steel, aluminum, or cast iron. Material selection will depend on the specific application of the pump and the heat resistance, pressure, and durability requirements of the system.

Oil supply line: This is where hydraulic fluid (usually hydraulic oil) is introduced into the pump to start the operating process. This is one of the important factors to ensure the pump has enough hydraulic fluid to create pressure and work effectively.

The location of the oil inlet line may vary depending on the type and design of the hydraulic pump.

Oil outlet: is where hydraulic fluid (usually hydraulic oil) is taken out of the pump after the pump has created pressure. This line transfers hydraulic fluid from the pump to other hydraulic components and systems in the application.

The location of the oil outlet may vary depending on the type and design of the hydraulic pump.

Seal: is an important part of the pump, it helps prevent hydraulic fluid from leaking out and keeps pressure maintained in the pump. There are several different types of seals in hydraulic pumps, and each type of seal has its own distinct function and application.
