Because of the complex design of the whole structure of the fire engine pump, the staff needs to prepare the work in advance.Usually, before starting the fire engine pump, it is necessary to carefully check whether the voltmeter on the control cabinet is 24 volts.If it is below that level, the cause needs to be identified and excluded.
Next, the site staff should also check that the connection parts are intact to see that there are no abnormal problems.Then check whether the oil in the oil sump, the fuel pump and the governor meet the specified oil level. If the oil is insufficient, it should be replenished in time.In addition, if the fire engine pump adopts open circulation cooling system, the water should be connected first.
For users, the main characteristic of the fire engine pump is its own independent power supply system - battery.Because of this, the device can be completely disconnected from municipal power during start-up and operation.In practice, the device is usually used as a backup facility.Therefore, only when the fire signal comes and the electric pump fails, or when the power is off, will it start itself.
It should be noted that, if the fire diesel pump is also equipped with ultra-low pressure starting pump device, the electric pump control cabinet which is also used with the pump should also have ultra-low pressure starting pump device, and the lower limit of both should maintain a proper pressure difference.Of course, if the customer has special needs, then the specific requirements can be combined to design a more appropriate control system.
In addition, if you want to improve the reaction capacity of the fire engine pump, it should be checked regularly during daily use.It's best to check once a week.Due to the hydraulic hammer effect and the performance characteristics of the diesel engine, the engine should be started at a low speed during the inspection, and then slowly accelerated to the speed required by the fire.http://www.wandiengine.com/
