Description
Piping Learning System composition
The water supply and drainage object model is designed with a stainless steel frame as a whole. The main water supply and drainage piping equipment is installed on the steel frame base and has the characteristics of an open mode. It consists of a domestic water supply system, a fire water supply system, a drainage system and a control system.
The domestic water supply system mainly consists of a water supply tank, a water supply pump, a water supply pipeline, a pressure transmitter, a pulse water meter, a faucet and a shower head. The pipeline is designed with stainless steel composite pipes, which can be used for cutting, installation and water test operations of stainless steel composite pipes. Through the control system, the variable frequency and constant pressure water supply function of the domestic water supply system can be realized, and the single pump frequency conversion control or double pump switching control can be realized. Function; water consumption can be measured by pulse water meter.
The fire water supply system mainly consists of water supply tank, sprinkler pump, air pressure tank, wet alarm valve, fire alarm controller (linkage type), pressure switch, water flow indicator, fire water supply pipeline, closed sprinkler head, etc. The pipeline is designed with galvanized pipes, which can be used for cutting, threading, installation and water test operations of galvanized pipes. The sprinkler and fire extinguishing function can be realized through the control system.
The drainage system mainly consists of sewage tank, liquid level sensor, drainage valve, drainage pipe and water treatment unit. The drainage pipeline is mainly designed with UPVC pipes, which can be used for cutting, bonding, installation and water test operations of UPVC pipes. Combined with the control system, it can realize the water level detection of the sewage tank and the start and stop control of the drainage pump.
The water supply and drainage automatic control system mainly includes electrical control cabinets, touch screens, operating switches, working status indicators, PLC controllers, inverters, low-voltage electrical, water pumps, water meters, sensors (float level gauges, pressure switches, water flow indicators) , Signal butterfly valve, pressure transmitter), configuration monitoring software, etc. The automatic control function of the water supply and drainage system can be realized through the control system.
