White RE Series Hydraulic Motors Replacement

 

Hydraulic motors are devices that are powered by hydraulic pressure to convert hydraulic energy into mechanical energy. The main purpose of hydraulic motors is to convert hydraulic fluid pressure into rotary motion or mechanical energy. These motors come in different forms and sizes, including gear and vane motors, piston motors, and other specialty types. In this article, we will discuss how hydraulic motors are started and what factors contribute to their efficient and smooth operation.

 

The hydraulic motor's starting sequence usually involves several essential steps. The first step is to prime the hydraulic system with fluid. This process ensures that the motor is well lubricated and ready to receive the high-pressure fluid flow that powers it. Next, the control valve that regulates the hydraulic fluid flow is activated to allow the fluid to flow to the motor.

 

It is essential to note that hydraulic motors require a minimum level of pressure to operate efficiently. This pressure is referred to as the motor's "pressure drop." The pressure drop is determined by the design of the motor and varies depending on the size, type, and application of the motor. The pressure drop of the motor must be within the recommended range to ensure smooth operation and longevity.

 

Once the control valve is open, the hydraulic fluid flows into the motor, creating pressure and rotating the motor's shaft. The hydraulic fluid pressure provides the necessary torque to rotate the motor's shaft and apply the required mechanical force to a load. The hydraulic motor's output torque is proportional to the input fluid pressure, so the higher the fluid pressure, the higher the output torque.

 

One critical factor that contributes to the efficient operation of hydraulic motors is the type of hydraulic fluid used. The hydraulic fluid must meet specific viscosity, temperature, and lubrication requirements to ensure optimal performance. Hydraulic fluid that is too thick or too thin can cause the motor to overheat, leading to reduced efficiency and eventual damage. In contrast, hydraulic fluid that lacks proper lubrication properties can lead to increased wear and tear on the motor's moving parts.

 

In addition to proper fluid viscosity, the hydraulic system's cleanliness is crucial to the motor's smooth operation. A contaminated hydraulic system can cause damage to the motor's internal components, leading to premature wear, reduced efficiency, and ultimately, motor failure. Therefore, it is essential to maintain a consistent maintenance schedule and keep the hydraulic system clean and free of contaminants.

 

In conclusion, hydraulic motors are an essential component of many industrial and mobile applications. The smooth and efficient operation of these motors is critical, and their starting sequence must follow specific steps to achieve this. Proper hydraulic fluid, pressure, and system cleanliness are just a few factors that contribute to optimal motor performance. By ensuring these factors are met, hydraulic motors can provide efficient and long-lasting service.

◎ The intermittent operating pressure refers to the Max. allowable operating pressure at the motor inlet port, and the continuous operating pressure refers to the pressure difference between the inlet port and the return port.

◎ Do not operate the motor at the Max. speed and the Max. pressure at the same time.

◎ The motor operating time per minute must not exceed 10% under intermittent operating conditions.

◎ Recommended oil: anti-wear hydraulic oil; Viscosity: 37-73cst; Oil cleanliness: IS018/13.

◎ Max. oil temperature: 80℃.

◎ The series motor adopt special imported shaft seal assembly. The Max. allowable back pressure of the motor can be up to 10MPa; however, in order to obtain the good service life and comprehensive mechanical performances, the back pressure should not exceed 5MPa. If it is exceeded, it is recommended to connect the external drain pipe; when connecting the external drain pipe, ensure that the motor is always filled with oil. When connecting the external drain pipe, in addition to maintaining a low back pressure, the wear contaminants generated inside the motor can be removed and a certain cooling effect can be achieved.

◎ There should be a running-in period before the motor is operated at full load. It is recommended to run for 1h at 30% of the Max. operating pressure.
