【 Weak current College 】 sprinkler system frequently asked questions in the cause and treatment---Power By 【 China power house network 】

1. system composition
Closed sprinkler, water meter, wet alarm valve, pressure switch, regulators pumps, spray pump, spray control cabinet.

2. the main features of the system completed

The system is in normal operation, the pipeline has a certain pressure of water, fire, the fire temperature reaches the temperature of the closed-head, broken glass, nozzle spray foam, pipe water from static to dynamic, the water flow indicator, signal transmission to the fire Centre of fire control cabinet alarm, alarm when wet alarm device, pressure switch action, through the Control Panel start spraying pump for water supply pipe, complete system of fire-fighting capabilities.

3. system easy problems, causes, simple processing method

(1) voltage appliance starts heavily. Cause: the main front-end for wet equipment leaks, plumbing fittings or connections spill, leak, closed type nozzle tip relief device not for good. Treatment methods: check all plumbing, sprinkler and end-relief device, identify leaks point for processing.

(2) flow indicator in water movements and not the signal. Cause: in addition to electrical lines and terminals pressure lines, mainly flow indicator itself, including pulp tablets fixed, pulp tablets damaged, broken or fretting switch Reed pipe-contact burned, or don't work a permanent magnet. Treatment method: check the pulp slice for damage or death, check the permanent magnet, Reed pipe, and other devices.

(3) after the end of the nozzle movement or relief device open after the linkage pump without water pipeline front-end. Cause: mainly for the wet alarm valve not action, wet alarm device can not be sent to the frontend pipes for water. Treatment method: check the wet alarm equipment, mainly butterfly valve, until the flexible flip, and then check the other parts of the wet plant.

(4) joint action signals, do not spray pump. Cause: possible to control devices and fire pump start Cabinet wiring of loose or device failure or mechanical failure of the spray pump itself. Treatment methods: check the wiring and the pump itself.
