The performance and advantages of constant pressure tangent fire pump; variable flow constant pressure ( the pressure always remains unchanged in the case of flow change ), the dead point does not exceed the pressure, the investment is less than the life pump, the difference is: Vitamins,Vitamin B5,Vitamin D,Vitamin B4,Vitamin K PYSON Co. ,Ltd. , https://www.pysonbio.com
(1) The fire flow is relatively regular. The fire hydrant water supply system is incremented by 5L/s . The sprinkler system is incremented by a flow value corresponding to a light hazard, a medium hazard, and a severe hazard.
(2) The fire pump is used to ensure the water quantity and water pressure of the fire fighting water. It involves personal safety and property protection and must be reliable. The pump body is required to have a reasonable structure, appropriate material and high reliability.
(3) The water supply for fire pumps generally uses water pumps directly to the fire-fighting facilities ( fire hydrants, sprinklers ) . Provide water for small flows during initial fire or self-test operation, and supply water at design flow during the fire development phase. When the pump flow rate to head curve is steep, it is easy to generate overpressure phenomenon during small flow operation, and corresponding technical measures should be taken.
(4) The fire pump is used for fire extinguishing, and the requirements are prompt and timely. The fire pump has a short water diversion time and good starting performance.
2. XBD-HY constant pressure tangent fire pump is a new type of fire pump. The outlet pressure during operation is gentle. When the flow rate changes, the head is almost unchanged. It is especially suitable for the variable current regulation requirements in fire protection. The structure has two types: straight vertical and direct horizontal. The XBD constant-pressure tangential fire pump motor adopts Y2 long-axis motor. The impeller is radial open type, no ring, no corrosion, and the operation is particularly stable.
The tangential pump is used for fire protection and is now changed to a construction fire pump, which is renamed as a variable current regulator pump.
When the fire pump inlet and outlet pipes are connected by clamps, check valves, butterfly valves, pressure relief valves, etc., and other fire protection valves should be provided with grooves at the interface.
