【 Weak current College 】 foam fire engine maintenance method

Fire fighting foam fire engine as the main battle vehicles maintenance aspects must be in accordance with the national standard GB7956-1998 or industry standard GA39.5-92 requirements. Combined with the use of foam running circumstances do maintenance is important. In the ongoing maintenance, in addition to the usual on automobile engine, chassis, and other parts for maintenance, you need to do maintenance work.
1. after washing foam
In order to ensure the fire pump to reliable work, per-use foam or salt water, irrigation and fire pump, water pump, foam proportioner is a very important process of moving water treatment pump is connected to either side, foam, exporting wells plugged into water purification; water running pump primers, on the use of low-voltage operation, open the foam; open-water pump valve outlet, adjust the speed to be increased to maximum pump pressure; complete rinsing after 0.5MPa, adjust the pump speed is lower than the export pressure 0.2MPa, open water, the pump until you exhaust pipe net flow in and out.
2. other considerations for maintenance
Periodically fire trucks for maintenance of the parts is very important, mainly: ensure fire engine has enough fuel, lubricating oil, cooling water, gas, power. And regularly replace; always check circuit, circuit and fire protection systems are functioning, various instruments, lights, switches, lights are intact; jugs, foam tank according to the standard quantitative filled with water and foam liquid; periodically (every two days) test check engine, power take-off and drive system, each day a vacuum to ensure water pump system performance standards; various valves and active parts to regular lubrication, periodically check its flexibility; check cited water pump, water pump gearbox, power take-off at the oil level is at the location, oily calibrating compliance with standards such as oil deterioration, should be replaced immediately; vehicles should be scrubbed clean, the outer surface with a clean soft cotton towel to dry, then get on the wax to ensure vehicle appearance gloss, while at the same time keep pumping stations, equipment box clean, equipment placement, maintain garage clean, dry and cold season garage temperature not lower than 10 degrees Celsius.
