Use and operation procedures of diesel engine fire pump
The diesel engine fire pump is started in manual mode and automatic mode respectively. In manual mode, the field control cabinet must be started and stopped. In the automatic mode, it starts as a remote operation and also needs to stop the operation of the field control cabinet.
Configuration description of diesel engine fire pump control cabinet:
1. Diesel engine fire pump control cabinet is equipped with: Start button, stop button, diesel engine acceleration button, diesel engine deceleration button, instrument panel to display oil pressure, speed and water temperature;
2. The control cabinet is also equipped with power LED, operation indicator, stop indicator, diesel engine acceleration indicator, diesel deceleration indicator and fault alarm LED;
3. You can select "automatic" or "manual" operation status on the control cabinet, remote monitoring status;
Inspection before start of diesel engine fire pump
1. Check whether the fuel tank of diesel engine fire pump (more than 1 / 2 of the fuel tank) is sufficient;
2. Check whether the water level of the diesel engine fire pump water tank is sufficient (at the top of the diesel engine cooler, open the cooling water spray cover before starting);
3. Check whether the oil level of diesel engine fire pump is appropriate
4. Check whether the inlet and outlet valves of diesel engine fire pump are open;
5. Check the normal battery voltage (24V) of diesel engine fire pump and the water level in the battery (the voltage in the upper right corner of the control cabinet requires local inspection of the battery water level)
Diesel engine fire pump manual start
1. The diesel engine pump can be started after normal detection;
2. Turn on the start mode switch on the control cabinet at the "manual" position, and press the "diesel engine start" button on the control cabinet for 2 seconds to start the diesel engine fire pump;
3. After the diesel engine runs at low speed for about half a minute, press the "diesel acceleration button" for one second, then release it, the speed will rise, and then press the "diesel acceleration button" for one second after it is stable. The secondary diesel engine gradually increased to a speed of about 1610 rpm, and then the "diesel acceleration button" did not work, indicating that the diesel engine fire pump began to reach the set value, and the pump operation was observed on site. If the diesel engine speed is too high (the system protection stops automatically after exceeding 1650rpm), it is necessary to press the "diesel engine deceleration" button to reduce the speed to the rated speed.
Automatic start of diesel engine fire pump on site
1. In automatic mode, there are two modes: automatic start and remote operation start
2. At this time, press the "automatic" mode to press the control cabinet start mode button;
3. Press the "start" button of diesel engine fire pump remotely;
4. At this time, the diesel engine fire pump automatically performs the start-up, acceleration and constant speed process without human intervention.
5. In automatic mode, it can only be started but not stopped. Stop operation in the control cabinet.
Local shutdown of diesel fire pump
1. When it is necessary to stop the diesel pump, press the "diesel engine deceleration" button for 1 second, the speed will decrease, and then press the "diesel engine deceleration" button for 1 second. After several times, the speed of the diesel engine dropped to about 840 rpm, no longer dropping. The description has been simplified to "idle" state.
2. Press the "diesel engine stop" button for 3 or 5 seconds, release the button after the diesel engine stops completely and stop.
Rules for regular inspection of fire pump room equipment
1. Start the diesel engine fire pump every half a month for at least 10 minutes to ensure that the diesel engine fire pump is in good standby state; check the pipeline flange and system prompts. No leakage, ensure the system is in good condition;
2. Before each start-up, the oil level, water level and storage battery of diesel engine fire pump shall be comprehensively inspected according to the inspection items.
3. If the speed cannot reach the set value when the speed rises or falls, contact the maintenance personnel and adjust the speed limit switch
