The biggest difference between the diesel engine fire pump and the electric water pump is that it has its own independent power supply system – the storage battery. Therefore, the start and operation of the diesel engine fire pump do not depend on city power at all.
The diesel engine fire pump is usually used as a backup facility, so it will only start automatically when the fire signal comes, and when the electric water pump fails or the power supply is cut off. When it has a device for starting the pump at ultra-low pressure, its matching electric water pump control cabinet should also have a device for starting the pump at ultra-low pressure, and the lower limit of the two pumps should have a certain pressure difference.

    What kind of terrain to choose what kind of water pump

    This problem, in short, is the selection of water pumps. The following are the applicable way for you to choose water pumps from zjbetter. I hope they can help you choose water pumps and help you better. Choose the water pump that suits your design.
    1. Confirm the use terrain
    First understand the terrain in which the outfit is used, including temperature, moisture, air pressure, air cattiness, dustproof and leakproof conditions, and the position of dangerous areas.
    2. Confirm operating conditions
    Refers to the liquid face pressure( absolute) on the suction side of the liquid, the liquid face pressure on the discharge side, intermittent or nonstop work, fixed or mobile position, and the convenience of installation and conservation.
    3. Confirm the nature of the medium
    Medium temperature, viscosity, density, impregnated vapor pressure, solid flyspeck periphery and content, gas content, cattiness, volatility, trap, toxin.
    4. elect the material of the pump bathe corridor
    According to the physical and chemical parcels of the pumped medium above, the material of the inflow- passing corridor is determined.
    5. Determine performance parameters
    The performance parameters of the water pump can be determined by computation, analogy, test and other styles.
    6. Determine the installation type
    The installation of the channel is determined by the layout of the channel and the installation point, and there are direct connection, perpendicular and other types.
    8. Determine the number of pumps
    In general, spare pumps, especially fire pumps, are set up, and the number of pumps is named according to different situations.
