 DW-YD multi-position welding fume purification system (central smoke purification system) 

 Welding fume control system is divided into two forms: 
 A welding fume efflux 
 Welding area above each station to install the appropriate length of the suction arm, the radius of its activities cover the entire welding area completely. 
 System uses high-pressure centrifugal fan, blower operation will cover the mouth of the negative pressure suction arm space, this time by welding fume suction arm, pipe reducers, and finally through the fan at high altitude emissions. 
 Sucked directly from the source of harmful welding fumes and workers to operate so as to achieve the purpose of protection. 
 In this way simple and efficient construction cycle is short, and the system is less air resistance, the effect of smoking is good, low cost system. 
 B welding fume emission purification 
 Such forms of governance need to be equipped with the system above, welding fumes purifying the host, the host of a major role for the purification absorbed by the system of welding fumes, welding fumes purification because the other host has some drag, so the need to increase the pressure in the design centrifugal fan air flow in order to achieve good cleaning effect of smoking. At the same time meet the national requirements of the exhaust gas emissions standards. 
 First, the system benefits 
 1, flexible suction arm to balance the design, any stretching, rotation can be freely positioned. 
 2, multi-level design universal joint, the welding operation, may change with welding position hood can be adjusted at the position and angle to get the best collection of dust effects. 
 3, suction hood with air flow control valve and the human hand, to prevent foreign matter is inhaled, the entrance hood with protective net. 
 4, the hood can be rotated 360 degrees of freedom, at any time to adjust to absorb smoke the best results. 
 5, the suction arm for the metal used in wire-type hose inside and outside the PVC coated glass fiber hose, tube diameter? 160mm high temperature and corrosion resistance. 
 Second, the scope of application: 
 1, due to large-scale production requirements, the workshop produced by the multi-station welding fumes, etc., I developed the company's central smoke purification system to meet a number of different stations while welding fumes generated by cleaning of the collection needs. 
 2, the central charge of road dust cleaning system, through an extension to the side, the pipe may need to use T-, I-type, adjustable tube, 90 
 Degree elbow connection, and a safety fixtures, installed at each station over a desired length of the suction arm (or suction 
 Cover) This is an absorption, filtration, purification of the complete set of the central dust extraction systems.
