What is the difference between constant pressure fire pump and ordinary fire pump?

[Asia Pump Network News] XBD- HY constant pressure tangent fire pump is a new principle of fire pump. Xiao Bian to introduce constant pressure fire pump and ordinary fire pump What are the differences? Constant pressure fire pump constant pressure fire pump and ordinary fire pump difference (1) relatively regular fire flow. Hydrant water supply system to 5L / s as the number of increments. Sprinkler systems correspond to light, intermediate, and dangerous levels of serious dangerous levels of flow value increases. (2) The fire pump is used to ensure the water quantity and pressure of the fire protection water, which involves personal safety and property protection and must be reliable. Require the pump structure is reasonable, the material is appropriate, high reliability. (3) fire pump water generally used by the pump directly to the fire extinguishing facilities (hydrants, sprinklers) water supply. In the initial fire extinguishing or self-test operation for the small flow of water supply, fire in the development phase of the design flow of water supply. When the pump flow ~ lift curve is steep, it is easy to produce overpressure when the small flow operation, which should take appropriate technical measures. (4) fire pump for fire extinguishing, prompt, timely, the corresponding requirements of the fire pump water short time, good starting performance. (5) constant pressure fire pump constant flow (in the case of flow changes in the pressure remains unchanged) off point does not over-pressure, less land. (6) constant pressure fire pump outlet pressure relief when running smoothly Changes when the head is almost constant, especially for fire in the flow regulator requirements, the structure has a straight vertical and direct horizontal two. (7) The motor of the constant pressure tangent fire pump adopts the Y2 plus long axis motor. The impeller is radial open type, no mouth ring, no corrosion and the operation is particularly smooth. (8) Fire pump inlet and outlet pipes When using the clamp connection, check valves, butterfly valves, pressure relief valves, etc., and other fire valve components should be provided at the interface groove.
