The main purpose of the vertical fire pump is to transport clear water without solid particles, or a liquid that is particularly similar to water. Its function is to pressurize and deliver water to the fire protection system. Of course, it also has the function of drainage. The pressure range of the transported liquid is 0.2~2.25 MPa. The caliber range is; 50~; 200mm. The water flow range is 5~80L/s.
The main purpose:
Vertical fire pumps are mainly used in pipeline pressurized fire protection systems. They can also be used in industrial and urban water supply and drainage, high-rise building pressurized water, long-distance water, hot and cold water cycle pressurized heating, toilets and boilers, water supply and supporting equipment for air-conditioning and refrigeration systems equipment etc.
A new vertical multi-stage fire pump, including water inlet section, middle section, outlet section, impeller, main shaft and guide vane, the impeller is installed in the guide vane and discharge section through the main shaft, and the guide vane is set in the middle. Shell shape, the final stage impeller is directly installed in the volute.
The new vertical multi-stage fire pump has no final guide vane in the outlet section. The water is directly discharged from the end impeller, then enters the volute channel in the outlet section, and then discharged from the water outlet. This can improve the flow state of water, reduce energy loss, and improve Pump efficiency, greatly reducing the vibration and noise of the pump.

(1) Two or more suction pipes, when one of the suction pipes is under maintenance or damaged, the rest of the suction pipes should still pass 100% of the total water consumption, production and fire water pump room life and share, when life and production For water use, 100% of fire-fighting water should still be guaranteed; for the fire-fighting water pump room set independently, when the suction pipe is damaged, other water suction pipes should still ensure 100% water consumption.
(2) High-pressure fire pumps, fire pumps, and fire pumps should have independent suction pipes to ensure that the fire pool or municipal pipe network can directly absorb water and provide fire water.
(3) Appropriately use the tank body to absorb water. This water absorption method is often used to fill the fire pump, which can quickly start the fire pump to ensure fire water. If there is any difficulty, reliable water filling equipment should be provided.
(4) In order to ensure that the circular pipeline has a reliable water source, the fire pump should not be smaller than two outlet pipelines and be connected with the circular pipeline. When two outlet pipelines are used, each outlet pipeline should be able to satisfy all water supply. As a maintenance process One of the outlet pipes, the rest of the pipe can still provide all the water. The outlet pipe of the pump and the loop system should be connected on different sections to ensure the safety of water supply.
The fire pump should run regularly or regularly, lubricate the part, and measure the pressure and flow after starting the fire pump. Therefore, set the fire pump outlet pipe to check and test the drain valve.
