When it comes to the installation of BM3 Series Hydraulic Motors, there are several crucial factors that need to be taken into consideration. This article aims to provide you with informative guidelines and important points to keep in mind during the installation process. From understanding working pressures to recommended oil viscosity, we will cover everything you need to know to ensure a successful installation. 

1. Understanding Intermittent and Continuous Working Pressure

It is essential to differentiate between intermittent and continuous working pressures. Intermittent pressure refers to the maximum pressure that the motor can handle during short bursts. On the other hand, continuous working pressure refers to the pressure difference that the motor can withstand during prolonged operation. It is crucial to adhere to these pressure limits to avoid motor damage and ensure optimal performance.

2. Avoiding Excessive Pressure and Speed

To prevent any potential damage to the BM3 Series Hydraulic Motor, it is important not to operate it under the highest pressure and maximum speed. Exceeding these limits can lead to premature wear and tear, reducing the motor's lifespan. Therefore, it is advisable to operate the motor within the recommended pressure and speed ranges specified by the manufacturer.

3. Adhering to Intermittent Working Time

Under intermittent working conditions, the motor should not exceed 10% of its total running time. This means that the motor should have sufficient rest periods to prevent overheating and maintain its efficiency. It is crucial to monitor the running time and ensure that the motor operates within the recommended limits to avoid any potential issues.

4. Recommended Hydraulic Oil

For optimal performance and longevity of the BM3 Series Hydraulic Motor, it is recommended to use N68 anti-wear hydraulic oil. The viscosity of the oil should be within the range of 37-73cSt, and its cleanliness should adhere to the ISO18/13 standard. Using the recommended oil will ensure proper lubrication and minimize the risk of damage or malfunction.

5. Maximum Working Temperature

The BM3 Series Hydraulic Motor has a maximum working temperature of 80℃. It is essential to monitor the temperature during operation and avoid exceeding this limit. Operating the motor at excessively high temperatures can lead to reduced efficiency and potential damage. Proper cooling mechanisms should be in place to maintain the motor within the recommended temperature range.

6. Running Time Before Full Capacity

Before operating the BM3 Series Hydraulic Motor at full capacity, it is advisable to run it for at least one hour under 40% of the maximum working pressure. This allows the motor to warm up gradually and ensures optimal performance when operating at higher pressures. Following this recommendation will help prevent any potential issues during full capacity operation.

7. Back Pressure Considerations

The maximum allowable back pressure for the BM3 Series Hydraulic Motor is 10MPa. However, it is recommended to keep the back pressure below 5MPa to ensure efficient operation and avoid unnecessary strain on the motor. If the back pressure exceeds the recommended limit, it is crucial to install a leaking pipe to release the excess pressure and prevent damage to the motor.

Conclusion

Proper installation of the BM3 Series Hydraulic Motor is essential for its optimal performance and longevity. By understanding the working pressures, avoiding excessive pressure and speed, adhering to recommended working times, using the appropriate hydraulic oil, monitoring the temperature, and considering back pressure, you can ensure a successful installation. Following these guidelines will help you maximize the efficiency and lifespan of the BM3 Series Hydraulic Motor, ultimately leading to improved productivity and reduced maintenance costs.
