The purpose of a hydraulic pump is to generate hydraulic fluid flow in a closed circuit system. It is an essential component of a hydraulic system, which is a widely used method of transmitting power in industrial machinery and equipment. The hydraulic pump works by converting mechanical power into hydraulic power through a process called fluid displacement. The mechanical input is typically provided by an electric motor or a combustion engine.
The hydraulic fluid generated by the pump is used to drive hydraulic machinery, such as cylinders and motors, in order to accomplish various tasks. The hydraulic system offers several advantages over other methods of power transmission, such as electrical or mechanical systems. For example, the hydraulic system is capable of delivering high power density, precise control, and can operate in harsh environments.
There are several different types of hydraulic pumps available on the market, including gear pumps, vane pumps, and piston pumps. The type of pump used in a particular application depends on the specific requirements of the system, such as flow rate, pressure, and temperature.
In summary, the purpose of a hydraulic pump is to convert mechanical power into hydraulic power, which is used to drive hydraulic machinery in a closed circuit system. The benefits of using a hydraulic system include high power density, precise control, and the ability to operate in harsh environments.
