Product working principle and operation methods

Excavator hydraulic rotary motor is the core component of excavator rotary system, and its working principle and operation method are very important for the safe and efficient operation of excavator.

【 Working principle 】 :
Excavator hydraulic rotary motor adopts closed hydraulic circuit, which is mainly composed of hydraulic pump, hydraulic motor and hydraulic control valve. When the driver adjusts the operating lever through the control handle, the hydraulic pump begins to work, and the hydraulic oil is sucked from the hydraulic tank, filtered through the filter, and entered the hydraulic rotary motor.

In the hydraulic rotary motor, under the action of high pressure of hydraulic oil, the rotor inside the driving hydraulic motor begins to rotate. The movement of the rotor is converted into power, which makes the hydraulic motor rotate. At the same time, the hydraulic control valve of the hydraulic rotary motor plays the role of regulating the hydraulic oil flow and pressure, so as to achieve the accurate control of the rotation speed and direction of the excavator.

[Operation method] :

Start the excavator: First, ensure that the hydraulic rotary motor of the excavator is stopped, and then start the engine, and open the oil supply switch of the main hydraulic system when the motor is stable.
Control rotation direction: By manipulating the rotation lever on the handle, adjust the hydraulic control valve of the hydraulic rotation motor to realize the switch of the rotation direction of the excavator. Push the lever left or right, and the excavator will turn counterclockwise and clockwise, respectively.
Adjust the rotation speed: adjust the rotation speed of the hydraulic rotation motor by pushing and pulling the operating lever. The further the lever is pushed, the faster the rotation speed, and the slower the rotation speed is when the lever is pulled back.
Stop rotation: When it is necessary to stop the excavator rotation, place the rotary lever in a neutral position, and the hydraulic rotary motor will stop rotating.
Safe operation: When operating the excavator, the surrounding environment should be kept smooth, and be careful not to collide with the excavator parts or other objects to ensure the safety of the operation.

With its exquisite working principle and simple operation method, excavator hydraulic rotary motor provides efficient and stable power support for excavator rotary system. Understanding its working principle and operation skills helps the driver to master the rotation operation of the excavator, improve work efficiency, and ensure the safe and reliable operation of the excavator in various construction tasks. The correct operation of the excavator hydraulic rotary motor will bring you a more smooth and pleasant construction experience.
