Product working principle and features

Excavator hydraulic rotary motor is an indispensable part of modern excavator. Its efficient and stable working principle and unique characteristics inject strong power into the rotary system of excavator.

【 Working principle 】 :
Excavator hydraulic rotary motor adopts hydraulic transmission closed hydraulic circuit, mainly composed of hydraulic pump, hydraulic motor and hydraulic control valve. When the driver operates the excavator control rod, 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.

Inside 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 to drive the hydraulic rotary motor to 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.

【 Feature 】 :

High efficiency and stability: excavator hydraulic rotary motor adopts hydraulic transmission, and its working principle makes the rotary action efficient and stable. It can respond quickly to operation instructions, ensure the smooth rotation of the excavator, and improve the efficiency of the operation.
Large rotation power: Excavator hydraulic rotary motor has excellent rotation power, can easily be competent for all kinds of soil and rock excavation tasks. Its powerful rotating power makes the excavator have excellent digging ability and carrying capacity.
Precise control: The hydraulic rotary motor achieves accurate adjustment of speed and direction through advanced hydraulic control technology. The driver can flexibly manipulate the rotary action of the excavator to ensure accurate positioning and operation.
Energy saving and environmental protection: Compared with the traditional mechanical transmission mode, the hydraulic rotary motor has a higher energy utilization and lower energy consumption. Its energy-saving and environmental protection characteristics are in line with the pursuit of green environmental protection for modern excavators, which is conducive to reducing energy consumption and reducing emissions.
In general, the excavator hydraulic rotary motor plays an important role in the rotary system of the excavator by virtue of its exquisite working principle and unique characteristics. Its efficient and stable performance and diversified functions enable the excavator to complete various tasks efficiently and accurately under various complex engineering conditions. The excellent performance and reliability of excavator hydraulic rotary motor bring unlimited power to the mining industry and become a helpful helper for excavator operation.


Operation precautions

Excavator hydraulic rotary motor is an important part of the excavator, and special attention should be paid to safety and maintenance during operation to ensure the normal operation of the excavator and extend the life of the equipment.

[1, Check before operation] :

Make sure the excavator is shut down, and put the hydraulic rotary motor in the stopped state, and then carry out a comprehensive inspection before operation.
Check the hydraulic oil level to ensure that the hydraulic oil in the tank is sufficient, and be careful not to mix impurities.
Check whether the connection part of the hydraulic system is tight to prevent oil leakage and loose accidents.
[Two, rotary operation] :

Before operating the turn, ensure that there are no people and obstacles in the turning area to avoid injury or collision.
When controlling the rotary operating rod, it should be pushed and pulled smoothly, avoid violent shaking, and ensure smooth and smooth action.
Do not suddenly change the direction of rotation in the rotation movement, should stop the rotation and then change the direction.
【 Three, rotation speed control 】 :

When controlling the rotation speed, it should be adjusted according to the specific work needs to avoid accidental damage or inaccurate operation caused by too fast rotation.
Do not continuously rotate at high speed for a long time to avoid overheating and damage to the hydraulic system.
[Four, stop turning] :

When it is necessary to stop the rotation of the excavator, place the rotary lever in a neutral position to ensure that the hydraulic rotary motor stops rotating.
Ensure that the excavator is stopped before performing other operations or leaving the operation platform.
[Five, maintenance] :

Check the oil level and oil quality of the hydraulic system regularly, replace the hydraulic oil and filter in time, and maintain the stable work of the hydraulic system.
Pay attention to check the hydraulic pipeline and seals of the hydraulic rotary motor regularly, and replace the damaged parts in time to avoid oil leakage and failure.
[VI. Emergency Handling] :

In the event of an emergency, the rotary operating rod should be immediately placed in a neutral position to stop the rotary action, and emergency measures should be taken in time to ensure the safety of operation.
If the hydraulic system is found to be abnormal, abnormal sound or other faults, it should be stopped immediately for inspection and should not be forced to operate.

Following the above operational precautions is the key to ensure the safe operation of the excavator hydraulic rotary motor and extend the life of the equipment. When operating the excavator, it is necessary to attach great importance to safety and maintenance work, reasonably adjust the rotation speed, avoid sudden switching of the rotation direction, and regularly maintain the hydraulic system. Only by maintaining a high degree of vigilance and maintenance can we ensure the stable operation of the excavator, improve the efficiency of the operation, and provide reliable guarantee for the smooth construction of the project.
