XBD-HY vertical constant pressure fire pump, also known as tangent pump, has 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 flow range, its head changes within 5% range, and it does not overpressure at small or zero flow, thus avoiding the phenomenon of ordinary centrifugal pumps overpressure at small flow and inability to supply water at large flow in fire scenes.

The significance of XBD-HY vertical constant pressure fire pump model

XBD-HY vertical constant pressure fire pump is mainly used for water supply of fixed fire protection systems (hydrant fire extinguishing system, automatic sprinkler system and spray fire extinguishing system) in industrial and civil buildings, as well as water supply systems shared by fire protection and life (production), and water supply for buildings, municipal, industrial and mining, boilers and other occasions.

1. Vertical constant pressure fire pump is used for conveying clean water and other liquids with physical and chemical properties similar to clean water. It is suitable for industrial and urban water supply and drainage, high-rise building pressurized water supply, garden sprinkler irrigation, fire pressurization, long-distance transportation, HVAC refrigeration cycle, bathroom and other cold and warm water circulation pressurization and equipment matching. The operating temperature is T<80 ℃.
2. The IRG (GRG) vertical hot water (high temperature) circulation pump is widely used in energy, metallurgy, chemical, textile, papermaking, hotels, restaurants, and other boiler high-temperature hot water pressurized circulation transportation, as well as urban heating system circulation pumps. The IRG type uses a temperature T<120 ℃, and the PoGRG type uses a temperature T<40 ℃.
3. IHG type vertical pipeline chemical pump is used for conveying liquids that do not contain solid particles, are corrosive, and have a viscosity similar to water. It is suitable for industries such as petroleum, chemical, metallurgical, power, papermaking, food and pharmaceutical, and synthetic fiber. The operating temperature ranges from 20 ℃ to+120 ℃.
4. YG type vertical pipeline oil pump is used to transport petroleum products such as gasoline, kerosene, diesel, etc. The temperature of the transported medium is -20 ℃~+120 ℃. Long.

1. The suction pressure is ≤ 1.0MPa, or the working pressure of the pump system is ≤ 1.6MPa, that is, the pump suction inlet pressure+pump head is ≤ 1.6MPa. The static pressure test pressure of the pump is 2.5MPa. Please specify the system working pressure when ordering. When the working pressure of the pump system is greater than 1.6MPa, it should be separately stated when ordering, so that the overcurrent and connection parts of the pump can be made of cast steel materials during manufacturing.
2. Environmental temperature<40 ℃, relative humidity<95%.
3. The volume content of solid particles in the conveyed medium shall not exceed 0.1% of the unit volume, and the particle size shall be less than 0.2mm.
Note: If the medium used is with small particles, please specify when ordering so that the manufacturer can use wear-resistant mechanical seals.
