(2) Connect the flushing cooling water at the pipe joint of the mechanical seal chamber. (3) Fill the pump with water (4) Close the gate of outlet pipe and outlet pressure gauge. (5) Start the motor, when the pump runs normally, open the outlet pressure gauge and gradually open the gate valve until it shows the appropriate pressure. At the same time, check the motor load. (6) The flow and head of the pump should be controlled as far as possible within the range indicated on the pump label, so as to ensure the long-term operation of the pump near the high-efficiency point, so as to obtain the maximum / maximum energy-saving effect. (7) During the operation of the pump, the bearing temperature rise shall not exceed the ambient temperature by 35 鈩? and the maximum / maximum temperature shall not exceed 80 鈩? (8) If abnormal sound is found during the operation of the pump, stop the pump immediately to check the cause. (9) To stop using the pump, first close the gate valve, pressure gauge, and then stop the motor. (10) Pay attention to the lubrication of the bearing and inject grease into the bearing chamber regularly. (11) When the pump is used in the cold winter season, the drain plug at the lower part of the pump body must be unscrewed after the pump is stopped to drain the water completely to prevent frost cracking. (12) Long term use of the pump, the pump must be completely removed, wipe dry water, rotating parts and combinationChinaDredgePumpManufacturs website:http://www.pumpdelin.com/dredge-pump/
