XBD-HY constant tangent fire pump

XBD-H type constant tangent fire pump Product Overview XBD-H type constant tangent fire pump, is my company based on market needs and developed new products. Its performance and technical conditions in full compliance with GB6245-2006 "fire pump performance requirements and test methods" standards promulgated by the country's new. Product features This series fire pump with variable flow regulator characteristics, namely in the whole flow range, head changed little, basically a quasi-constant characteristics, so called XBD-H type constant tangent fire pump, this performance It features full compliance with the use of the characteristics of the fire scene, thus avoiding the ordinary centrifugal flow at fire scene small overpressure at high flow for no water phenomenon. According to constant pressure fire pump itself of the characteristics, combined with our specific situation, constant pressure fire pump is a horizontal structure. For 75kW or less (including 75kW) of constant pressure fire pump vertical structure may be used throughout the series are added to the long axis of the Y2-type direct-motor, eliminating couplings, which greatly improves the reliability of the pump unit; constant Fire Pump open impeller radial, axial force trachoma, no mouth ring, to eliminate the rust killed, so that it runs smoothly, low noise, and long service life. Pump casing made of cast iron, other flow components specific needs of stainless steel, bronze or other anti-corrosive material manufactured according to user. Usage XBD-H type constant tangent fire pump is mainly used for industrial, civil fixed firefighting systems (fire hydrant systems, sprinkler systems and water spray system) of water, in addition, can also be used for fire and life (production) sharing and building water supply systems, municipal, industrial, boiler feed water and other occasions. Working conditions Speed: 1480/2960 r / min flow rate range: 5 ~ 80 L / s Medium temperature: ≤80 ℃ water pressure range: 0.3 ~ 2.6 MPa Ambient temperature: max + 40 ℃
