Hydraulic Motors

The hydraulic motor is an actuator of the hydraulic system, which converts the liquid pressure energy provided by the hydraulic pump into the mechanical energy (torque and rotational speed) of its output shaft. Liquids are the medium through which force and motion are transmitted. Hydraulic motors, also known as oil motors, are mainly used in injection molding machinery, ships, hoists, engineering machinery, construction machinery, coal mining machinery, mining machinery, metallurgical machinery, shipbuilding machinery, petrochemical industry, port machinery, etc.

Product Description

hydraulic motor

The hydraulic motor is an actuator of the hydraulic system, which converts the liquid pressure energy provided by the hydraulic pump into the mechanical energy (torque and rotational speed) of its output shaft. Liquids are the medium through which force and motion are transmitted.

Hydraulic motors, also known as oil motors, are mainly used in injection molding machinery, ships, hoists, engineering machinery, construction machinery, coal mining machinery, mining machinery, metallurgical machinery, shipbuilding machinery, petrochemical industry, port machinery, etc.

Product Usage:

Hydraulic motors, also known as oil motors, are mainly used in injection molding machinery, ships, hoists, engineering machinery, construction machinery, coal mining machinery, mining machinery, metallurgical machinery, shipbuilding machinery, petrochemical industry, port machinery, etc. High-speed motor gear motor has the advantages of small size, light weight, simple structure, good craftsmanship, insensitivity to oil contamination, impact resistance and small inertia. Disadvantages include large torque pulsation, low efficiency, small starting torque (only 60%-70% of rated torque) and poor low-speed stability.

Features:

From the perspective of energy conversion, hydraulic pumps and hydraulic motors are reversibly working hydraulic components. Inputting working fluid to any hydraulic pump can change it to the working condition of the hydraulic motor; conversely, when the main shaft of the hydraulic motor is driven from the outside When torque drives rotation, it can also become a hydraulic pump operating condition. Because they have the same basic structural elements - a closed but periodically changing volume and a corresponding oil distribution mechanism. However, due to the different working conditions of hydraulic motors and hydraulic pumps, their performance requirements are also different, so there are still many differences between hydraulic motors and hydraulic pumps of the same type. First of all, the hydraulic motor should be able to rotate forward and reverse, so its internal structure is required to be symmetrical; the speed range of the hydraulic motor needs to be large enough, especially its minimum stable speed. Therefore, it usually uses rolling bearings or hydrostatic sliding bearings; secondly, because the hydraulic motor works under the condition of input pressure oil, it does not have to have self-priming capability, but it requires a certain initial sealing to provide the necessary starting torque. Due to these differences, hydraulic motors and hydraulic pumps are similar in structure, but they cannot work reversibly.
