Large pump station speed pump trip how to deal with?

Large pump station speed pump trip how to deal with? (A) shift officer emergency steps (1) immediately asked the control room operator level and host computer alarm situation. (2) According to the water level and the upper computer alarm to make the correct judgments. (3) order the control room operator to turn on the backup pump. (4) If there is no spare pump available, according to the actual situation of the tripping unit, order the pump attendant to change the control mode of the tripping unit automatically to the engine side and open the unit with the engine side under the condition of no fault of the host, To ensure the normal delivery of sewage. (5) order the control room operator and central control room dispatcher to get in touch, inform the situation, request the coordination of the water level, to ensure the rational delivery of sewage. (6) According to the alarm display items, inspect the equipment together with the pump attendant to find out the cause of the malfunction and eliminate the fault within the scope of the duty. (7) If you can not solve the problem, timely reporting to the owners, to listen to the views, take measures and make a detailed record. (8) In the handover, the next class of personnel to explain in detail the situation so that successors understand the situation of the equipment. (B) control room operator emergency steps (1) found that the fixed-speed crew suddenly jumped to immediately change the water level in accordance with the timely opening of spare units, and get in touch with the central control room, inform the situation, request coordination of water to ensure that the site Run at normal water level. (2) promptly notify the squadron of the water level rise and the host computer alarm display records. (3) record the time of failure, status, phenomenon. (4) to report to the owners of fault conditions and require instructions and advice. (5) standby unit to resume normal operation, the water level is stable, and then report to the central control room dispatcher and the owners of fault handling and unit operation status. (6) handing over to the next class of people explain in detail what happened, so that successors understand the situation of the equipment. (C) pump station attendant emergency steps (1) under the command of the squad leader and with the preparation of machine-side ready to open the crew. Machine side open speed set unit steps: ① the basic cabinet on the control mode to machine side. ② The hydraulic station control mode to local control. ③ 6kV control cabinet, with the key to the mode switch on-site. ④ Open the cooling fan in the basic cabinet, circulating cooling water, turn off the heater. ⑤ Open the hydraulic gate in the control cabinet of the hydraulic station. When the gate starts 5 to 10 seconds later, close the corresponding vacuum contactor in the 6kV control cabinet and turn on the pump. Machine side open siphon unit steps: ① The basic cabinet on the control mode to machine side. ② Open the cooling fan in the basic cabinet, circulating cooling water, turn off the heater. ③ In the basic cabinet off valve, while opening the vacuum exhaust valve. ④ press the machine side of the basic cabinet to open the pump button to start the pump. (2) with the squad leader to identify the reasons for the sudden speed jump unit fixed speed. (3) If the cooling water flow switch signal is interrupted, then manually adjust the signal. (4) If the vibration value trip, the basic cabinet vibration transducer reset. (5) In the case of a PLC fault, the PLC is powered off for a period of time before sending the power. (6) If the hydraulic station failure, then identify the possible fault location. (7) If the vacuum system centralized alarm, the vacuum device is powered off, restart. (8) If there is no pressure on the rupture valve, check whether there is any leakage of the compressed air line and repair it in time. (9) If the air compressor fails, the backup air compressor should be quickly turned on and off. The valves of the air outlet pipe, such as the air compressor pipe, are manually closed and the air compressor pipe, which is manually turned off, is opened quickly. (10) The result of the failure of the phenomenon, time, inspection and maintenance shall be recorded in detail. (11) In the handover, the next class of personnel to explain in detail the situation so that successors understand the situation of the equipment.
