The difference between the constant pressure fire pump and ordinary fire pump

The XBD series constant pressure fire pump is a new kind of principle of fire pump. Runtime outlet pressure gently lift almost unchanged when flow changes, particularly applicable to fire control in converter voltage requirements, the structure with straight league on vertical and horizontal two. XBD fire pump motor adopts Y2 extended shaft, impeller for radial open, no ring, no rust, special smooth running. Mainly applied to industrial and civil buildings fixed fire protection system ( Fire hydrant fire extinguishing system, automatic sprinkler system and spray extinguishing system) Water supply, also can be used for fire fighting and life ( Production) Shared water supply system and the construction, municipal, industrial and mining, boiler feed water and so on various occasions.

constant-voltage tangent fire pump performance and advantages: has the characteristics of the converter regulated, is within the range of flow rate, pressure changes small, pump flow from zero to the maximum flow required within the scope of changes, the pressure change in the 5% range, and small flow or no flow not overpressure, avoiding the ordinary centrifugal pump at the scene of the fire protection of small and medium-sized flow when excess pressure and large flow rate of water supply is not on the phenomenon. Under the condition of constant pressure fire pump in the flow change the pressure always remains the same, while the common fire pump if in the use of low head and large discharge situation will appear in excess of the current phenomenon, caused by serious burning motor) 。

the difference between the constant pressure fire pump and ordinary fire water pump:

1, the design standard. Constant pressure fire pump is the international standard. Constant pressure fire pump fully meet and exceed GB2645 - 98 standards, in line with international standards, accord with GB2645 - general fire water pump 98 standard.

2, through its own technical performance to achieve constant pressure pump, flat performance curve, within the scope of pump flow from zero to maximum flow changes, changes in lift is only 5 meters. Ordinary own technical performance of the pump to determine pump performance curve slope steep, parabolic, namely traffic xiao Yang into high and low flow high head, such as pump pressure is zero flow when the head design point 1. 3 to 1. Five times, form overpressure.

3, system: effective traditional pump technology in fire control system performance of ills, small flow or no flow in the overpressure big traffic step-down problems. General fire pump super pressure and large flow rate step-down small flow problems.

4, configuration, constant pressure fire pump system need not set the overpressure measures, can save proportioning valve or valve. And general system configuration to prevent overpressure facilities, the need for proportional control valve or valve.

5, material: pump flow components is made of cast iron or stainless steel plate, is not easy to rust and deformation. Generally easy to rust, easy to deformation.

6, pump start-up, constant pressure fire pump pump can start randomly, no stuck phenomenon. General pump cannot start randomly, easily jammed

7, appearance: constant pressure fire pump impeller is vertical Angle and end face; Import and export as a whole looks long and thin.

constant pressure fire pump and fire pump application difference is:

1) Constant pressure tangent fire pump used to ensure that the amount of water and fire water pressure, involve the personal safety and property protection, must be reliable operation. body structure is reasonable, material properly and high reliability.

      ( 2) Constant pressure tangent fire flow is relatively regular. Fire hydrant water supply system for 5 l/s series. Automatic sprinkler system to corresponding to the dangerous level, dangerous, serious danger of increasing flow value.

      ( 3) Constant pressure tangent fire pump generally adopt directly by the water pump of water supply to the fire-fighting facilities ( Fire hydrant, sprinkler) Water supply. In the initial attack or self-inspection runtime for small flow water, according to the design flow of water in the fire development stage. When the water pump capacity and head curve is steep, easier to produce in small flow runtime overpressure phenomenon, corresponding technical measures should be taken.

      ( 4) Constant pressure tangent fire pump used for fire fighting, for prompt, timely, appropriate for fire pump water diversion time is short, starting performance is good.
