The portable fire pump maintenance
1. Maintenance
The portable fire pump maintenance should be carried out in a ventilated and dry place. External dust and oil stains should be removed and the amount of lubricating oil should be checked on schedule.
after use, lubrication in various motion states should be protected. The spark plug should be removed for inspection when the pump rotates for a cumulative 50 hours. The pump should operate for a cumulative 100 hours to remove the carburetor and remove dust from the paper core of the air cleaner. After the pump runs for a cumulative 200 hours, in addition to the 100 hours of maintenance work, the crankcase bottom cover should be removed and cleaned. After the pump runs for a cumulative 400 hours, the wear of the piston and piston ring should also be checked. The pump is used by hand, it should be cleaned and placed on a dry and clean wooden frame.
2. Precautions
- Do not knock with iron tools when disassembling and assembling parts, and prevent sundries from falling into the machine during disassembling and assembling.
- When reassembling, all parts should remain in their original positions. Spark plugs should always remove carbon deposits and oil stains.
- When reassembling, gaskets and other gaskets must not be missing, nuts and other must be tightened, especially the fan flywheel nuts.
3. Portable fire pump troubleshoot
- If the pump is found to be in abnormal condition during use, it should immediately stop running, find out the cause and eliminate it.
- When a failure occurs, do not blindly disassemble the parts of the hand-held pump, and analyze the cause of the failure.Then suit the remedy to the case to be ruled out.
- Operational faults can be eliminated quickly. If they are caused by insufficient inspection and maintenance at ordinary times, it will take a lot of time to solve them, but fire fighting is a matter of minutes and seconds, so it should be avoided that fire fighting aircraft will be delayed due to troubleshooting only when they are in use.
