PLC intelligent double control firefighting pressurization pressure-stabilizing water supply device

Abstract

Provided is an intelligent double control firefighting pressurization pressure-stabilizing water supply device. Running of a pressure-stabilizing water pump and an air compressor is respectively controlled by utilizing control signals collected by a liquid level float valve arranged on an air pressure water tank and an electric contact pressure gauge through a PLC intelligent control cabinet, the air pressure ratio in the water tank is controlled strictly by the double control effect, gas is supplemented when lacked, the regulating water quantity is increased, and the regulating water quantity during a firefighting period is guaranteed. Compressed gas in the tank is effectively prevented from entering a pipe network and having the reaction of combustion supporting during the power outage and water supply stopping period of the device due to the arrangement of air stopping valves in the tank. The whole device detects pressure of the air pressure water tank, the water volume and water level conditions of a water box through PLC centralized control, corresponding water supply parameters are displayed and set and water supply records are inquired on a touch screen, and the intelligent double control firefighting pressurization pressure-stabilizing water supply device has stability in control and convenience in management, saves energy, performs control in a more standard mode, runs distinctly, is low in failure rate and is always in an ideal state.

Description

technical field [0001] The invention relates to a fire-fighting water supply equipment, in particular to a PLC intelligent double-control fire-fighting pressurized and stabilized water supply equipment. Background technique [0002] At present, most of the fixed fire-fighting water supply equipment in the fire-fighting market are bladder type, diaphragm type and buffer type air pressure water tanks. Capsule and diaphragm air pressure water tanks are in a static and non-working state all year round, and the long-term humidity and temperature changes cause the capsule and diaphragm to age and crack, which greatly increases the maintenance rate and shortens the service life. However, the buffer water supply equipment is clumsy in operation, and the gas in the tank is easy to enter the pipe network, which plays a negative role in supporting combustion. At the same time, it is difficult to manage these types of equipment in place. The time and type of failure are not well do...

AI Technical Summary

Problems solved by technology

Capsule and diaphragm air pressure water tanks are in a static and non-working state all year round, and the long-term humidity and temperature changes cause the capsule and diaphragm to age and crack, greatly increasing the maintenance rate and shortening the service life.

However, the buffer water supply equipment is clumsy in operation, and the gas in the tank is easy to enter the pipe network, which plays a role in supporting combustion.

At the same time, it is difficult to manage these types of equipment in place. The time and type of failure are not well documented. The air pressure ratio of the air pressure water tank is unstable. , The equipment is in an unsatisfactory state for a long time, which may easily cause fire hazards and cause irreparable losses
