Before starting the YHB shaft oil pump, make sure to perform a thorough inspection: http://
**1. Pre-Start Inspection:** Before operating the YHB shaft oil pump daily, ensure that the return valve is fully open and the valve block is in the closed position. After completing the test, all valves should be returned to their designated positions as per the system diagram. The inlet valve must always remain open, while the outlet valve should be closed during initial checks. In case of an emergency or fire drill requiring oil, open the valve corresponding to the fire (foam) supply and close the return valve accordingly. **2. Starting and Stopping the Pump:** Once the pump is started, monitor the motor’s running current and the oil pump’s operation. If any unusual sounds, vibrations, or temperature spikes are detected, stop the pump immediately. After the pump begins to operate properly, move the clutch handle of the vacuum suction device to the “on†position. Observe the outlet pressure gauge; when it reaches the rated working pressure and stabilizes, gradually open the outlet valve to ensure the pump operates under normal conditions. Always check the temperature of the pump and motor bearings—never exceed 75°C—and verify that the motor’s current remains within the normal range. When stopping the pump, return all valves to their standard positions according to the valve configuration diagram. Open the bleed valve to reset the float assembly and prepare the system for potential use. **3. Maintenance and Care:** Regularly inspect the power supply and electrical circuits of the fire protection system to ensure they are in good working condition. Every shift, check the coupling for smooth rotation and listen for any abnormal noises. Document any irregularities found. Additionally, keep a record of all maintenance activities and ensure that all components are clean, lubricated, and functioning properly. By following these steps, you can ensure safe and efficient operation of the YHB shaft oil pump, reduce the risk of mechanical failure, and maintain readiness for emergency situations. Always refer to the manufacturer’s guidelines for specific details and procedures. For more information, visit: http://://news.chinawj.com.cn
