Hydraulic Drive Excavators

Yushan Intelligent has our own factory and is also a Hydraulic Motors manufacturer and supplier in China. Welcome to consult if you have any questions.

As the "power heart" of Hydraulic Drive Excavators, the hydraulic motor equipped by Yushan Intelligent adopts an axial plunger structure design, which combines high efficiency and high reliability. Its core advantage lies in its outstanding energy conversion efficiency, which can efficiently convert the energy of hydraulic systems into mechanical power, reduce power loss, and cooperate with the energy-saving mode of excavators to improve operational efficiency while reducing fuel consumption. In terms of power output, hydraulic motors can generate strong torque without the need for complex gearboxes. By adjusting their displacement, constant power transmission can be achieved, and stable power output can be maintained whether it is low-speed excavation or high-speed transfer. Precise control is another highlight of the excavator. With the flow and pressure regulation of the hydraulic system, the motor can accurately control the speed and rotation position, allowing the excavator to move precisely and accurately during fine operations. In terms of durability design, the optimized lubrication structure inside the motor effectively reduces wear and tear. Even in harsh working environments with high temperatures and dust, it can reduce the occurrence of failures and extend the service life. At the same time, its compact structural design makes installation and maintenance more convenient, and maintenance personnel can complete routine inspections and maintenance from the ground, reducing equipment maintenance costs.

Yushan Intelligent Hydraulic Drive Excavators' hydraulic motor, with excellent adaptability, showcases its hardcore strength in diverse scenarios. At the site of urban building demolition, facing the crushing operation of reinforced concrete structures, the hydraulic motor drives the bucket to vibrate high-frequency and maintain stable torque, and cooperates with the flexible rotation of the machine body to accurately handle construction waste and avoid affecting surrounding buildings. In mining operations, complex terrain and hard rocks impose strict requirements on power output. Hydraulic motors continuously provide strong power to drive the tracks smoothly forward, while also driving the boom to complete high-intensity excavation. Even under frequent load fluctuations, there will be no downtime issues. At the pipeline laying site of municipal engineering, in narrow spaces, the precise speed control achieved by hydraulic motors allows the excavator to move smoothly, excavate trenches accurately, and ensure the accuracy of pipeline installation. In the field water conservancy renovation project, the sealing design of the hydraulic motor effectively isolates water vapor in muddy and humid environments, ensuring continuous operation of the equipment and assisting in the smooth formation of irrigation channels.

Q&A:

Q1: In Hydraulic Drive Excavators, if the hydraulic motor shows weak rotation, what could be the possible reasons?

A1: This issue is usually related to a reduction in the energy input to the hydraulic motor. It might be due to insufficient oil pressure within the system, which makes it impossible to overcome the operational resistance. It could also be caused by excessive frictional resistance between the plunger and the mating parts inside the motor, or a decrease in the mechanical efficiency of the transmission box. First, check the pressure of the hydraulic system, and then inspect the lubrication and wear conditions of the mechanical transmission parts.

Q2: What are the key points of daily maintenance for hydraulic motors?

A2: Regularly check the oil level and quality of the hydraulic oil on a daily basis, and replace the deteriorated oil in a timely manner. Check whether the motor seals are in good condition to prevent oil leakage and impurities from entering. Regularly tighten the motor connection parts to ensure stable transmission. Replenish the grease in accordance with the maintenance manual to reduce the wear of internal components. At the same time, keep the exterior of the motor clean to facilitate the timely detection of abnormal overheating and other issues.

Q3: Will the performance of hydraulic motors be affected in different work scenarios?

A3: Yushan Intelligent's hydraulic motor has been designed to adapt to multiple scenarios and has stable performance in conventional operating environments. However, in extremely low temperature environments, it is necessary to replace the hydraulic oil that is compatible to prevent an increase in oil viscosity from affecting motor start-up; In high-altitude areas, slight fluctuations in hydraulic system pressure may occur due to changes in air pressure. Professional debugging can be used to ensure that the motor maintains its optimal working condition, and overall it has strong environmental adaptability.
