Daily operation management and maintenance of fan manufacturers

1. Record the operating parameters (air outlet pressure, negative pressure, guide vane opening, motor current, oil temperature, oil pressure, indoor temperature) on time. 2. Check whether the oil level in the fuel tank is normal. 3. Check whether the motor is running normally and whether there is any abnormal noise. 4. Check whether the frame filter of the air inlet chamber is normal, damaged or loose. 5. Sanitary cleaning and fire safety inspection of the computer room. 6. When running in summer, the blower manufacturer's room should open the door, open the window, and open the axial flow fan to ventilate and cool down, and the door on the blower manufacturer's control cabinet should be opened to reduce the temperature in the cabinet. 7. If the operating condition of the blower manufacturer does not change and the negative pressure decreases, it can indicate that the filter is damaged or loose, and it should be stopped for maintenance. 8. The criterion for judging that the MCP panel of the blower manufacturer is in the automatic state is that the AUTO light on the panel is on. 9. Press the emergency stop button before repairing and maintaining the blower manufacturer. 10. The power supply regulations of our factory require that it is strictly forbidden to connect the temporary construction power supply from the power cabinet of the blower manufacturer's room to prevent accidents from causing the switch of the 1# substation to supply power to this power cabinet to trip. This is mainly to protect the blower manufacturer. , Because if the blower manufacturer suddenly loses low pressure during operation, it will cause loss of control and loss of lubrication, which will seriously damage the blower manufacturer. 11. The ventilation fan can be turned off when the electric blower manufacturer runs in winter, but the ventilation fan should also be turned on when the biogas blower manufacturer runs in winter, because the biogas blower manufacturer consumes indoor oxygen during operation, and a small amount of waste gas is discharged. Ventilation can cause injury and downtime. The blower manufacturer is a mechanical air supply system, and its function is to supply air for the aeration grit chamber, A-stage aeration, B-stage aeration tank and sludge aeration tank. There are 3 KA10S-GA250 electric blower manufacturers and 2 biogas-driven blower manufacturers produced by HV-TVRBD in Denmark, all of which are centrifugal blower manufacturers and are the heart of the factory. Among them, the electric blower manufacturer has a single The power is 500kw, the rated voltage is 10kv, the rated current is 33A, the speed is 3000 rpm, the blowing volume is 6360-14133 m3/h, and the pressure difference is 0.912bar; the biogas blower manufacturer has a single power of 400kw and a speed of 1500 rpm. The blast volume is 5100-11300 m3/h. The structure of the electric blower manufacturer, the electric blower manufacturer, the blower manufacturer: 1. Main engine, transmission mechanism, working mechanism. The host is the motor. The transmission mechanism includes a coupling and a gear transmission. The working mechanism includes impeller, diffuser, volute and seal, etc. 2. Lubrication system The lubrication system includes oil tank, oil pump, cooler, filter, etc. The principle is that under the action of the oil pump, the lubricating oil in the oil tank enters the gearbox after cooling and filtering to lubricate and cool the gears, and then returns to the oil tank , reciprocating cycle. 3. The oil cooling of cooling system blower manufacturers generally includes water cooling and air cooling. The water cooling system includes pools, pumps, coolers and cooling towers. 4. There are four types of air purification methods: oil curtain type, rolling curtain type, electrostatic type and oil immersion type. 5. The instrument monitoring and automatic control system differs from the blower manufacturer for the purpose and content of instrument monitoring. The instrument monitoring of the blower manufacturer in our factory mainly includes oil temperature, oil pressure, current, guide vane opening, air outlet pressure, negative pressure, vibration, etc. . The blowing volume of the blower manufacturer is proportional to the air outlet pressure and the blowing efficiency. There are two main ways to control the air pressure of the blower manufacturer: adjust the motor speed (opening degree of the guide vane); second, adjust the air line valve. The normal operation of the blower manufacturer should avoid small flow and high pressure, otherwise it is easy to cause surge.
