Additional information

General Instructions

The basis for the development of this project was the contract for the development of design documentation No. 2009.

The working documentation is developed on the basis of the design task, specifications and drawings of architectural and construction layouts of the facility. The project shall be read together with projects 2506PS.SOUE, 2506PT.

This section of the project provides for equipping the building of the Leisure and Entertainment Center with an underground parking lot on the street. Malyshevaskovskaya in the Verkhisetsky district in Yekaterinburg with a system for controlling the automatic fire extinguishing installation.

Object Characteristics:

The object is a 9-story building, with an underground parking lot: 1... 9 floors - Leisure and Entertainment Center; 2, -3 floor - underground parking. Bearing structures - assembly steel structures, columns and support beams - steel I-beams. Flooring floors made of monolithic reinforced concrete. The height of the premises is up to 5.5 meters.

Ventilation is natural and forced.

Purpose:

The implementation and proper maintenance of fire protection systems is designed for effective protection of premises by detecting, reporting and suppressing the source of combustion at the beginning of a fire.

The automatic control system for fire pumps and shutoff valves is part of the building fire protection systems, designed for remote control of fire pumps and electric valves.

Algorithm of automatic fire extinguishing equipment operation.

The volume of instrumentation fully complies with the requirements of the issued task and provides the necessary control over the operation mode of the equipment of the automatic fire extinguishing plant and internal fire water supply.

Pump Group 1:

PN1, PN2 and PN3 fire pumps constantly are in not working, waiting mode. When opening the section KC1 or/and KC2KC17 valve on a signal of pressure indicators, BP1, BP2 on the valve, the control unit and BSU3 No. 1/1-9/1 alarm systems forms a signal "Fire". To the received signal, the central device "CP1M" gives a command to the control units of BUZ1 No. 2/2; 2/3, BUZ1 NO. 2/4; 2/5 to open bypass and inlet gate valves ZD1, ZD2 and command to start fire pumps for BUPN1 No. 1/2, No. 1/3.

Control units of fire pumps BUPN1 No. 1/2.1/3 at confirmation signal "START" from relay BSU3 No. 10/1 generate pulse for switching cabinets SHUN No. 13 for starting of main pumps .

Start-up of pumps PN2 and PN3 is performed with time delays of 5 and 10 seconds between start-up of main pump PN1. If any main pumps do not reach the operating pressure of 0.60.7 MPa or do not start the pump PN1, PN2, PN3, the standby pump PN4 starts in 20 seconds according to the signal of "Output" ECM PS5 (PS6, PS7).

It is provided to protect PN1PN4 pumps from dry running, when the water level drops below 0.7 m in the fire tank according to the signal of the lower level sensor ROS301, BUN1, the start of PN1PN4 pumps is blocked.

The pipeline network of section 1 - 17 above KS1 - KS17 valves is filled with water and is under air pressure of 0.7 MPa.

Maintenance of working pressure in sections 1 - 17 is carried out by jockey - pump H5.

When the pressure drops to 0.65 MPa, according to the signal of ECM PS12 BUPN3 No. 1/4, the N3 pump starts. Upon reaching the pressure of 0.7MPa ECM PS12, disconnects the pump H3.

It is provided to protect the H3 pump from dry stroke, when the pressure decreases to 0.05 MPa at the input of the H3 pump ShUV No. 5, upon a signal from ECM SP11, it blocks the start of the H3 pump.

Water control in the fire tank:

When the water level in the tank decreases below the elevation, 2.0m, according to the signal of the level sensor ROS301 "Medium level" BUZ3 No. 2/3; 2/4, inlet gate valves are opened. Upon reaching the maximum level above the level of 6.0m BUZ3 No. 2/4; 2/5 the input valves are closed. Upon reaching the minimum permissible water level of 0.7 m in the tank by the signal of the level sensor ROS301 "Emergency lower level" BUZ3 No. 2/4; 2/5 generates signal on CP1M "Emergency level in fire tank."

Water monitoring in drain pit:

When the water level in the pit rises above the maximum elevation equal to 0.5 m, by the signal of the level sensor ROS301 "Middle level" BUPN3 No. 1/4, the drain pump DN starts. When the pit is completely emptied to elev. 0.1m, according to the signal of the level sensor ROS301 "Minimum level" BUPN3 No. 1/4, the DN pump is switched off. Upon reaching the maximum permissible level of water in the pit, by the signal of the level sensor ROS301 "Emergency level" BUPN3 No. 2/7, the pump room flooding generates a signal to CP1M.
