What could be the reasons for a fire sprinkler pump pressure gauge showing no pressure? This could be due to a faulty pressure gauge, a closed control valve on the pressure gauge, a closed floor valve in the piping, the roof water tank in the system room being empty, or the pump operating manually with a possibly malfunctioning automatic system function. Sprinkler pumpAutonomous expansion is achieved through the explosion of glass spheres at the high temperature in the pipeline nozzles of various protection zones, which causes the pipeline water flow to activate, and then triggers the alarm valve pressure switch to operate, reaching the autonomous expansion sprinkler pump. The water flow indicator联动 module or the alarm valve pressure switch wiring leads to the control room, where the fire control room can accurately reflect its action signals. Additionally, the control room should be able to directly control the start and stop of the sprinkler pump. Generally, the fire pump mentioned in the fire protection planning and construction refers to the hydrant pump. While the hydrant pump and the sprinkler pump have different uses in the system, the root cause of all the differences is actually the fire pump itself, with only varying parameters (flow rate, head, power, etc.). This is due to the different flow rates and pressures of the hydrant system and the sprinkler system set up in the system. Assuming that the structure and function are the same.

Sprinkler pumps are a type of fire pump. The fire pump typically mentioned in general planning and construction refers to the hydrant pump.Spray PumpFire pumps, although differing only in their application within the system—whether it's for a fire hydrant or a sprinkler system—the fundamental classification remains the same. The distinctions lie in their parameters such as flow rate, head, and power, due to the varying flow and pressure requirements of the hydrant and sprinkler systems. In terms of structure and function, they are essentially identical. Sprinkler pumps are a type of fire pump. Sprinkler pumps: The self-priming of sprinkler pumps is achieved by the glass balls in the nozzle of the piping network of each protected zone shattering under high temperatures, causing the water flow in the network to activate. This triggers the pressure switch of the alarm valve, reaching the goal of self-priming the sprinkler pump. The water flow indicator module or the alarm valve pressure switch is connected to the control room, where the fire control room can accurately reflect its action signals. Additionally, the control room should be able to directly control the start and stop of the sprinkler pump. Points to note for fire sprinkler pumps: At the fire pump room site, it is recommended to test both manual and automatic methods for fire pumps and sprinkler pumps. Complete the water test and check the interlock function of the system; inspect the functionality of the alarm valve group, observing the pressure gauges before and after the valve, and ensure there are drainage facilities at the test water valve. After the water test, check if the timer, hydraulic siren, and pressure switch activate, and if the sprinkler pump initiates promptly.
