Hydraulic motor high speed is still very common in life, Hanjiu has also manufactured a lot of related products, and has received good feedback with excellent quality, let's take a look at hydraulic motor high speed.
The main features of hydraulic motor high speed are: high speed, small moment of inertia, easy to start and brake, high sensitivity of speed regulation and commutation. Usually the output torque of hydraulic motor high speed is small, so it is also called high-speed small torque hydraulic motor. Hydraulic motor high speed has gear type, vane type, axial plunger type and so on.
The hydraulic motor makes the hydraulic system output speed and torque to drive the working parts to rotate. In terms of working principle, the hydraulic pump and hydraulic motor in the hydraulic system work by the change of the closed volume, and in principle they are reversible, but there are differences in structure and cannot be universal.
First, the selection of high-speed motor probably needs to consider the following issues:
1. Hydraulic motor speed range.
2. Starting torque and continuous working torque of hydraulic motor.
3. The working force of the hydraulic motor (for example, driving the fan is not an ordinary hydraulic motor, and the thrust or pull force received by the motor should be considered)
4. Hydraulic motor oil circuit, there is a series of columns, then pay special attention.
5. Installation space and design cost.
High-speed motors generally use plunger motors, of course, gear motors are also used in many places, and vane motors are also high-speed motors, but they are not common.
Second, the difference between high-speed and low-speed hydraulic motors
High-speed motors have the advantages of small size, light weight, simple structure, good workmanship, insensitivity to oil pollution, impact resistance and small inertia. The disadvantages include large torque pulsation, low efficiency, small starting torque (only 60%-70% of the rated torque) and poor stability at low speed.
Low-speed hydraulic motor is simple structure, reliable work, many varieties and specifications, low price. Its disadvantages are large volume and weight, and large torque pulsation.
The speed of the hydraulic motor has a lot to do with the torque. Although you can adjust the speed by flow, the torque of the motor is configured according to the design requirements. Hydraulic motor selection should pay attention to: 1. Speed; 2. Rated flow; 3. Torque; 4. Rated pressure; 5. Installation method.
