Fire pump fire pump is different from life pump, has its special requirements. Fire pump in the implementation of national standards today, fire pumps for cutting pump has been available. The characteristics of the tangential pump and some changes brought to the fire water supply network are introduced.
Construction of water supply and drainage engineering pump, all for the general pump. Whether it is used for domestic water supply, water supply for production, fire water supply or water supply to tanks or water tanks or water supply directly to water utilities, universal pumps are used. In fact, different purposes, different occasions, the pump requirements are not the same, should be based on their different circumstances, the selection of a suitable pump, universal pump to the direction of dedicated pumps is an inevitable trend.
(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.
