plc intelligent double control fire booster water supply equipment

Abstract

An intelligent dual-control fire-fighting pressurized and stabilized water supply equipment, through the PLC intelligent control cabinet, using the control signals collected by the liquid level float valve and the electric contact pressure gauge set on the air pressure water tank, to control the stabilized water pump and the air compressor respectively Through this dual-control effect, the air pressure ratio in the water tank is strictly controlled, the air is deficient and the air is replenished, and the water volume is increased to ensure the water volume adjustment during the firefighting period. The setting of the gas stop valve in the tank effectively prevents the gas in the tank from entering the pipe network caused by the compressed gas in the tank entering the pipe network during power outages and water cut-offs of the equipment, which plays a negative role in supporting combustion. The whole set of equipment is centrally controlled by PLC to detect the pressure, water capacity and water level of the air tank, and display and set the corresponding water supply parameters and query water supply records on the touch screen. The control is stable, the management is convenient, energy saving, and the control is more standard. Standardization, clear operation and low failure rate ensure that the equipment is always in an ideal state.

Description

Technical field [0001] The present invention involves a fire -supply -supply equipment, which specializes in a PLC intelligent dual -control fire pressure voltage stabilization equipment. Background technique [0002] At present, most of the fixed fire supply equipment in the fire market is a capsule, diaphragm, and buffer air pressure tank.Bypass and diaphragm -type air pressure tanks Due to the static and non -working state of the equipment for the year, the changes in humidity and temperature for a long time cause the capsules and the diaphragm to be prone to aging and cracking, which greatly increases the maintenance rate and has a short service life.The buffer -type water supply equipment is awkward, and the gas in the tank is easy to enter the pipe network, which can be reaction to combustion.At the same time, the management of these equipment is difficult to be in place. The time and category of the fault can be checked. The air pressure ratio of the air pressure water tan...

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
