Diesel engine fire pump is composed of diesel engine and fire pump, pump group in the form of horizontal, single suction, Diesel Portable fire pump multistage centrifugal fire pump. It has the characteristics of high efficiency, wide performance range, safe and stable operation, low noise, long life, easy installation and maintenance. For conveying clean water or other liquid similar in physical and chemical properties to water. It can also be used to transfer hot water, oil, corrosive or abrasive media by changing the material of pump flow parts, sealing forms and adding cooling systems.Diesel Portable fire pump
1, the correct maintenance of diesel engine fire pump, especially preventive maintenance, is the most easy, Diesel Portable fire pump the most economic maintenance, so it is the key to extend the service life and reduce the cost of use. For daily maintenance, check the fuel amount in the fuel tank as follows: Observe the fuel amount in the fuel tank and fill it as required.
2. Check the oil plane in the oil pan: observe whether the oil surface reaches the line mark on the oil ruler. When insufficient, it should be added to the specified quantity, but it can not exceed the upper limit of the line.
3. Check the oil plane of the injection pump governor: if the diesel engine fire pump does not reach the specified line mark, it should add enough oil (some injection pump governor does not have a ruler, this step can be omitted).
4. Check whether there is enough grease in the oil injection point of the water pump: remove the oil injection nozzle on the diesel engine circulating water pump and observe whether the lubricating oil is sufficient. If not enough, use the oil gun to inject enough grease into the water pump.
5. Check whether the water in the water tank is sufficient: it is found that the water in the water tank is insufficient and should be supplemented in time. The water added should be clean fresh water, such as tap water or clean river water. If the direct use of groundwater, easy to form scale in the tank, affect the cooling effect and cause failure, therefore, groundwater softening rear can be used. In the north (ambient temperature below zero), the appropriate freezing point antifreeze must be configured according to the local minimum temperature.
6, check the fuel injection pump drive connection plate: check whether the connection screw is loose, if loose, should be recalibrated injection advance Angle, and tighten the connection screw.
7. Clean the appearance of diesel engine and auxiliary equipment: wipe the oil stains, water and dust on the surface of the fuselage, turbocharger, cylinder head and air cleaner with a dry cloth or a cloth dipped in diesel; Wipe or blow with compressed air to remove dust from the surfaces of rechargeable generators, radiators, fans, etc.
The biggest difference between diesel engine fire pump and electric water pump is that it has its own independent power supply system – battery, therefore, the start and operation of diesel engine fire pump can be completely separated from the relationship with the mains.
Diesel fire pump is usually used as a backup facility, therefore, only when the fire signal comes, and the electric water pump failure or power failure in the case of automatic start. Diesel fire pump when it has the device of ultra-low pressure pump, and its matching electric pump control cabinet, there should be a device of ultra-low pressure pump, and the lower limit of the two pump should have a certain pressure difference. Of course, we can also design a more suitable control system according to customer requirements.
