It has an important position in the hydraulic system. There are many classification criteria for hydraulic motors, which can be generally categorized into high speed small torque and low speed high torque in the traditional industry. Due to the low-speed high torque hydraulic motor with low-speed stability and structural perfection, as well as with the hydraulic technology continues to high-pressure, high-power direction, people pay more and more attention to environmental protection, the requirements of hydraulic actuating elements with low noise, low pollution, smooth operation and other characteristics. Low speed high torque hydraulic motors are becoming more and more popular.
1. Characteristics of low-speed high-torque hydraulic motor
(1) Low-speed stability
An important performance of high torque motor is low speed stability, low speed stability in addition to the traditional sense of the description of the motor in the rated load, the lowest speed without crawling phenomenon. In the field of hydraulics also use speed pulsation rate to define its indicators, when the speed pulsation rate of 10% or less, known as the speed of the stability, and vice versa, is not stable.
(2) Structural stability
For high torque hydraulic motor, the structure of the perfect is another important performance, can be used to transfer the weight of the unit power and unit volume of the power can be transferred to assess. High torque hydraulic motor efficiency characteristics is also an important performance, including volumetric efficiency, mechanical efficiency and total efficiency. Relative to high-speed small torque hydraulic motor, high torque hydraulic motor has high efficiency, good low-speed performance and starting characteristics, and low noise. Well-structured high-torque hydraulic motors have rated working pressures between 14MPa and 35MPa, total efficiencies between 0.75 and 0.90, starting torque efficiencies between 0.8 and 0.95, and minimum stabilized speeds between 0.5r/min.
2. Advantages of low-speed high-torque hydraulic motor
(1) High-torque hydraulic motors are suitable for low-speed, high-load work. Many heavy equipment, such as excavators, bulldozers, cranes, etc., need to perform tasks at low speeds. Hydraulic motors are able to provide a constant and stable high torque output at low speeds, ensuring that the equipment can efficiently complete its tasks.
(2) High-torque hydraulic motors are designed with a focus on providing powerful torque for heavy-duty and low-speed operation. Compared with traditional electric motors or internal combustion engine drives, hydraulic motors are able to provide higher torque at lower speeds, ensuring that the equipment is able to overcome larger loads and accomplish tougher tasks.
(3) The hydraulic system works in such a way that high torque hydraulic motors can work stably under high loads for long periods of time. Even during long periods of continuous operation, the hydraulic motors remain highly efficient, reducing the frequency of equipment downtime and improving productivity.
Low speed high torque hydraulic motors play an irreplaceable role in industry, agriculture and other fields due to their unique performance advantages and wide range of applications. With the continuous progress and innovation of technology, the performance of low speed high torque hydraulic motor will be further optimized and the application fields will be further broadened.
