Drawings of gas monitoring system for laboratory
Our organization has completed the installation and design of a monitoring system and alarm systems of dangerous concentrations of gases in the room.
DESIGNING OF A GAS MONITORING SYSTEM
The working documentation on the automation of the gas analysis system was developed on the basis of the TK, project and task of the Technological Complex (TK) in accordance with the current regulatory documents and guidance materials.
The control system of 20% NKPR for gasoline and ethanol vapors in the flushing PP is provided with a gas analysis system comprising a power supply and alarm unit BPS21M, local BMS signaling units and thermochemical sensor alarms DAT-M produced by FSUE SPO Analitpribor (Smolensk). The power supply and alarm system BPS21M and the local alarm unit BMS provide warning light and sound alarms when the NKPR reaches 20%, emergency ventilation is turned on in the room served. Similarly, the control of 20% NKPR on a pair of gasoline and ethanol in the area of washing PP and in the impregnating compartment.
At the cable section and the section for checking cable products, it is possible to control the maximum permissible concentration of carbon monoxide using the signaling device SOU-1 (pos.5a, 6a) manufactured by FSUE SPE Analitpribor (Smolensk). If the maximum permissible concentration of carbon monoxide in the air of the working area is exceeded, the light and sound alarms on the LDS -1.
PROJECT MONITORING DOCUMENTATION
In the impregnating compartment, MPC monitoring of toluene vapors is provided by means of the Binom-SV gas alarm (pos. 4a) of the IGS-98 series manufactured by FSUE NPP Delta. When the MPC exceeds the toluene vapor in the air of the working area, the light and sound alarms on the gas alarm device are turned on.
1. This drawing is made on the basis of the scheme email. connections and connections to external postings (sheet 3).
2. Symbols of electrical wiring on the plans in accordance with GOST 21.614-88.
3. The cable should be laid locally using cable structures included in the specification of this kit.
4. Procurement of cables to make after the control measurement of the length of the route.
5. Protective grounding (zeroing) to perform in accordance with the requirements of EIR Ch. 1.7.
6. The equipment installed on the walls should be mounted on the K241U2 profile.
7. Open the laid cables to fasten along the walls on horizontal sections with a pitch of 800 mm, on vertical ones - 500 mm. __
8. Protective pipes attached to walls with a pitch of 2500 mm.
9. Nozzles and openings in the walls and ceilings after the laying of cables to score easily penetrable fireproof material according to SNiP 3.05.06-85.
10. In hazardous areas, laying of pipes and cables, connecting them to electrical equipment to produce in accordance with the requirements of the Rules of code of conductors of chapter 7
