Constant pressure fire pump is a new product developed according to market demand, suitable for high-rise building fire water supply and domestic water supply. It is a reliable and high-quality fire pump. Its performance and technical conditions comply with the requirements of the national standard GB6245-2006 "Performance and Test Methods for Fire Pumps".

The XBD-HY vertical single-stage tangent fire pump set is mainly suitable for water supply in industrial and civil building fire protection systems (fire hydrant systems, automatic sprinkler systems, and water mist fire suppression systems). It can also be used in water supply systems shared by fire protection and daily life (production), as well as various occasions such as building, municipal, industrial and mining, boiler water supply, etc.

XBD-HY vertical single-stage tangent fire pump set product features:

Constant pressure fire pumps have the characteristics of variable flow and stable pressure, that is, within the full flow range, the head does not change much. When the tangent fire pump changes from zero flow to the required maximum flow range, its head changes within the range of 5%, and it does not overpressure at small or zero flow, thus avoiding the phenomenon of ordinary centrifugal pumps overpressure at small flow rates and water supply failure at large flow rates in fire protection sites. Greatly improved the efficiency of fire extinguishing and the safety and reliability of firefighting equipment and personnel. Based on the characteristics of the fire pump itself and our company's situation. The pump impeller is open, with low axial force and no mouth ring, which prevents rusting and biting. The pump body and pump cover are made of cast iron, and the impeller is made of stainless steel, bronze, or other corrosion-resistant materials according to user requirements

XBD-HY vertical single-stage constant pressure tangent fire pumpworking conditions

Speed: 1500, 3000r/min (synchronous motor speed);
Medium temperature: ≤ 80 ℃ (clear water);
Flow range: 5-80L/s Head range: 0.3-2.0MPa;
Rotation direction: The pump rotates clockwise when viewed from the motor end.

The constant pressure fire tangent pump is different from the domestic pump and has its own special requirements. Today, with the implementation of national standards for fire pumps, specialized fire pumps - tangent pumps - have been introduced. Constant pressure fire pumps have the characteristics of variable flow and stable pressure, that is, within the full flow range, the head does not change much. When the pump changes from zero flow to the required maximum flow range, its head changes within 5%, and it does not overpressure at small or zero flow, thus avoiding the phenomenon of overpressure at small flow rates and water supply failure at large flow rates in ordinary centrifugal pumps on fire prevention sites. Greatly improved the efficiency of fire extinguishing and the safety and reliability of firefighting equipment and personnel.

The constant pressure fire tangent pump is a vertical, horizontal, and split fire pump with a very compact structure, small footprint, reliable sealing mechanism, and reasonable internal structure. The overcurrent components are made of stainless steel and aluminum alloy, with high reliability, long service life, smooth operation, low noise, maintenance free, and lifetime warranty. The driving motor of the pump is a regular motor that does not require variable speed, which marks a major breakthrough in China's fire pump technology and will bring significant social and economic benefits.

Compare life pumps:
(1) The traffic is relatively regular. The fire hydrant water supply system increases in stages of 5L/s. The automatic sprinkler fire extinguishing system increases in flow rate values corresponding to the light hazard level, medium hazard level, and severe hazard level.
(2) Fire pumps are used to ensure the volume and pressure of firefighting water, which involves personal safety and property protection, and must operate reliably. Require a reasonable pump body structure, appropriate materials, and high reliability.
(3) The constant pressure fire tangent pump is generally used to supply water directly to the fire extinguishing facilities (fire hydrants, sprinkler heads) through the water pump. Provide small flow water supply during initial fire extinguishing or self inspection operation, and supply water according to the design flow during the fire development stage. When the flow head curve of the water pump is steep, it is easy to experience overpressure during low flow operation, and corresponding technical measures should be taken to address this issue.
(4) Fire pumps are used for extinguishing fires and require quick and timely response, with corresponding requirements for short water intake time and good start-up performance.

Instructions before starting XBD-HY vertical single-stage tangent fire pump set:
1. Rotate the coupling by hand, and there should be no jamming of the rotor components.
2. Open the inlet valve and exhaust valve to fill the pump chamber with water, and then close the exhaust valve;
3. Jog the motor to determine if the direction of rotation is correct;
function:
1. Fully open the inlet valve and close the outlet pipeline valve.
2. Connect the power supply, and when the pump speed reaches normal, open the outlet pipeline valve and adjust it to the desired operating point;
3. Observe whether there are any abnormal situations after the pump is running. If there are any abnormal situations, stop the pump immediately for inspection, handle them before running again;
parking:
1. After gradually closing the outlet valve, cut off the power supply;
2. Close the inlet valve;
3. If the ambient temperature is below 0 ℃, measures should be taken to keep warm.
