The cupboard of positive pressure of unexplosive of Beijing, the fume chamber of the positive pressure of unexplosive

The ones that were often remembered in the past are attentive, he let me can not be cold at the night either! Where but go now? Know early it is once of dream, I will not place love on a place! The cupboard of positive pressure of unexplosive of Beijing, the fume chamber of the positive pressure of unexplosive lets the dream be different, there is no result!


First, cupboard of positive pressure of unexplosive of Beijing, the fume chamber of the positive pressure of unexplosive, applicable scope:
1. This product is suitable for the chemical industry, off-shore drilling island, metallurgy, medicine, light industry, textile, food, biotechnology, spaceflight aeronautical engineering and war industry,etc. are in the bao zha gas or dust environment, as the three phase four wire system ‘ 380V/220V) Exchange the electricity distribution mains supply of the low-voltage apparatus or to the measurement instrument, analyze monitoring and control of components such as instrument, jian shi device, microcomputer touch-sensitive screen, high-power frequency converter,etc..
2. Suitable for a district, hazardous area of 2 districts.
3. Suitable for IIA, IIB, IICs, the temperature group is the bao zha gas atmosphere of T1-T4.
4. Install in indoor, the open air.
Second, cupboard of positive pressure of unexplosive of Beijing, the fume chamber unexplosive principle of the positive pressure of unexplosive
Adopt dielectric isolation to light the source unexplosive measure. Namely: It is full of clean gaseous cupboards of positive pressure in vivo to install user’s used electrical apparatus element in one, make the flammable and explosive mixed gas in the external environment unable to engage the electric spark or dangerous temperature that the electrical apparatus element produce in normal working hour, thus achieve the explosion proof purpose of the electric apparatus.
Third, cupboard of positive pressure of unexplosive of Beijing, the fume chamber products advantage of the positive pressure of unexplosive:
1.The cupboard of positive pressure of unexplosive of new, adopt differential pressure switch of Will of Germany of U.S.A. and instrument, adopt and import the component of air passage of inferior Dirk, pure mechanical control is safely more practical and more reliable. Autonomous system liquid crystal display, integrated and high, the volume is small, it is steady to run, have advantages such as visualities,etc..
2.The positive pressure type unexplosive switch board belongs to the forced draft type, the automatic pressure relief device of the mechanical type relaxes automatically when the atmospheric pressure in the cupboard is greater than 500PA, inner heat will discharge with the gas the case, ventilate and dispel the heat, when lower than 100PA, the acoustooptic alarm lamp calls the police, when lower than 50PA, automatic power off.
3.Use the oil-water separator, make the oil moisture open, keep entering inner air of the cupboard clean.
4.Our cupboard all use and flow the tube, and the material is all red copper pipelayings, not merely can filter a lot of incidentals, and still can make the atmospheric pressure in the cupboard keep balanced, really reach the unexplosive result of the positive pressure.
5.Last touch pad in we faceplate,inside and outside getting more safe and more reliable without being earthed,etc..
6.Use the ostiole outside the cupboard touch-sensitive screen of our positive pressure, prevent the smoke and dust, prevent the faulty action.
7.Little screw to reach seal, use 304 unsuitable to get rusty stainless steel at the the intersection of we and cupboard.

Fourth, cupboard of positive pressure of unexplosive of Beijing, the fume chamber products characteristic of the positive pressure of unexplosive
1. This product is mainly made up of cabinet, autonomous system, air-spreading system, alarm system, power distribution system; Cabinet made up of positive pressure lumen and one pair of lumens, positive pressure lumen installs users’ electricity distribution system element inside, built-in autonomous system of one pair of lumens.
2. The cabinet type products adopt GGD cabinet bracket, the structure, the seated installation of cable chute that the main bracket panel is about, play incoming line, Qianmen to operate, the back door is overhauled.
3. The box products adopt the welded construction of the high-quality steel plate, main facts, bracket panels are upper and lower structure, the installation of hung type, play incoming line, Qianmen to operate and overhaul.
4. The desk-top products of musical instrument adopt the high-quality steel plate to be folded and welded and shaped, main facts, bracket panels are the front and back structure, seated installation, play the incoming line, musical instrument platform to operate, the back door is overhauled.
5. Divided into ventilating type and compensating type according to the air inlet way. The ventilating type is as the incessant serial air supply, the working heat of installing of the positive pressure inside component of lumen can take away with the air passage, have very good heat-dissipating functions, are suitable for solving the heat-dissipating problem of the high-power unexplosive frequency converter; The compensating type supplies gas for the discontinuity, the positive pressure lumen should have good leak tightness, guarantee that it is narrow-minded to dawdle.
6. Users must offer the source of the gas, the requirement is: Is it empty to purify? ? ? Or nitrogen, the source of the gas is pigeonholed: 0.2- 0.8Mpa; Usually the Living instrument wind can meet the demands in users.
7. Steel plate material use the intersection of GB710-88 and cold rolling steel sheet generally, can also choose GB3280-84, become rusty steel material according to user’s request.
