Power supply: 380V, 50Hz;
Outer machine noise: 50 decibels, interior machine noise: 40 decibels;
Fall wet amount: relative humidity was at 65% o'clock, and 5L/ is little;
Mode of operation: line control machine;
Environmental protection refrigerant: R407C;
Off-premises station is the side-blown heat exchange, is of a size of: long 701 thick 568 is high by 703, and indoor set is for blowing on the return air down, lands movable type, and size long 1180 thick 240 is high by 620; Indoor set has the safe and reliable auxilliary heating arrangement of PTC electricity, and dehumidifying is used when not needing to freeze.
This clarifier 4 performance specifications:
1. renew the wind technology:
Because staff's not stationarity in the operation room relative closure, operation room.This clarifier 4 adopts DC frequency-changing technology to control the size that new wind motorized valve is controlled new wind input, thereby guarantees office work personnel's new wind demand and do not influence indoor Temperature and Humidity Control.
2. cleanliness factor control device:
Because clarifier 4 is not only wanted can the indoor original dust of purification run, operating personnel are when carrying out the crosslinked cable joint, operations such as polishing to cable also can produce dust, in order not make these dust be adsorbed on the cable splice joint, at first we carry out dust removal process with electrostatic precipitator, by airborne particle counter site environment is detected in real time then, feed back to the centralized intelligence control subsystem, control of conversion device control blower fan improves or reduces the purpose that clean wind rate of ventilation reaches cleanliness factor in the pulpit.
Automation mechanized operation platform 5 personnel of being mainly used in ascend a height and the interface of auxiliary two cut cables aligns, and guarantee that staff's joint can carry out safely smoothly.Characteristics such as this equipment adopts Hydraulic for lifting load principle, and the modularization assembly unit has flexible and changeablely, safe and reliable, stablizes, and is convenient and swift, easy to operate.But its height step-less adjustment is controlled by the centralized intelligence control subsystem.
Performance specification:
Two major parts before and after this automation mechanized operation platform 5 can be divided into, every bulk is all formed (so that can enter the tunnel face) by the fritter platform of 600*600, every fritter platform supports (can be betrothed to mobile feet) by hydraulic supporting feet, hydraulic supporting feet can be by self as regulating height as the hydraulic jack or being connected by fluid pressure line, by centralized intelligence control subsystem 1 centralized control, can there be difference in height the centralized control front and back, so that cable splice place height and human body operation highly keep sustained height, and be highly electrodeless adjustable.Adjacent two chain-waless are linked to each other by structural member, increase its bulk strength.Control center's outage, the hydraulic pressure self-locking.Platform material is made of durinvar, transport light, the intensity height.The mobile butt joint of cable also can be passed through Platform Implementation, because platform is a modular combination, each chain-wales all can be an independently lifting jack mechanism, when cable need move butt joint, the chain-wales of being betrothed to mobile feet can shift out integral platform separately and support cable, and the immigration operating platform, realize that cable moves butt joint.
Safe fire-fighting subsystem 6 has toxic and harmful is detected and warning function.Can the concentration of the indoor toxic and harmful of gas modulo operation be detected, reporting to the police automatically when the concentration of poisonous harmful gas surpasses normal value and sending ear-piercing buzzer returns to normal value or the people stops for closing just up to the concentration of toxic and harmful.Safe fire-fighting subsystem 6 has the function that fire alarm is reported to the police to operation room, the warning of when the condition of a fire occurring, sounding a buzzer automatically, and operating personnel can put out a fire with the dry powder extinguisher that carries.Centralized intelligence control subsystem 1 will be opened the safe escape door of gas mould automatically in 30 seconds.
Illumination subsystems 7 adopts explosion-proof clean light fixture, and the configuration emergency light.Lamp installation is on 2 structural members of gas modulo operation chamber, and the lamp power line is by discharging in the structural member, and structural member is made of the hard aluminium alloy hollow tubular, and is safe and reliable and attractive in appearance, disposes portable parallel light modulation simultaneously, but the quality of detection tabs Local treatment.
Centralized intelligence control subsystem 1 is the control center of this system, each functional block operate as normal is monitored and controls by 485 communication interfaces.
Centralized intelligence control subsystem 1 can be controlled the safety inflation of gas modulo operation chamber 2, is worked under safety air pressure in the modulo operation chamber 2 of bringing about the desired sensation, and the safe escape door of gas modulo operation chamber 2 also can have control subsystem control simultaneously.Centralized intelligence control subsystem 1 can effectively be controlled the ambient temperature and humidity of gas modulo operation chamber 2, the duty that can show gas modulo operation chamber 2, and can set the humiture of gas modulo operation chamber 2 as requested, temperature and humidity controller 3 will move automatically according to the operational order of centralized intelligence control subsystem 1.And have phase shortage, excess current, overvoltage, etc. defencive function.Centralized intelligence control subsystem 1 can be controlled the air quantity and the cleanliness factor of clarifier 4 automatically, adopt the air quantity frequency-changing control system, personnel's situation according to gas modulo operation chamber 2, air quantity to new wind carries out variable frequency control, automatically adjust the magnitude of recruitment of new wind, simultaneously the dust particle in the gas modulo operation chamber 2 is detected automatically, adjust the magnitude of recruitment of new wind according to the situation of dust particle automatically.Centralized intelligence control subsystem 1 can be to the lifting of automation mechanized operation platform 5, and displacement is controlled, and centralized intelligence control subsystem 1 can detect the concentration of toxic and harmful automatically, and reports to the police; Can carry out detection alarm to the fire alarm situation, and can in 30 seconds, cut off the electricity supply automatically, open emergency lighting.
