Requirements for the working environment of the fire pump group

The fire pump is mainly used to pressurize and send water to the fire system pipeline. It can also be applied to industrial and urban water supply and drainage, pressurized water delivery for high-rise buildings, long-distance water delivery, heating, bathroom, boiler cooling and heating cycle pressurized air-conditioning refrigeration system water delivery and equipment matching, etc.

1. Install the fire pump impeller directly on the extended shaft of the motor. The advantage of this installation is that the structure is very compact and can effectively balance the radial and axial loads generated by the pump operation. In this way, the pump can run smoothly with low noise .

2. There are vertical and horizontal installation methods for fire pumps, which should be installed according to the requirements of pipeline layout.

3. Regarding the installation and maintenance of the fire pump, it is very convenient, and the pipeline system needs to be dismantled.

    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.
