Welding of concentrated cleaner design considerations for concentrated cleaner should strive to closely, try to reduce the holes and gaps of a.
Airtight cover through the material of orifice should be set on elastic material dust cover curtain;
b。
Airtight cover should be as much as possible to avoid direct connection in vibration or reciprocating motion on the body of equipment;
c。
Adhesive tape machine by feeding point using roller, local subsidence due to material impact can make tape, the tape and sealed column board formed between aperture, cause dust to escape, so the density of the point of the roller should step up or convert plate;
d。
Closed hood impacts by material and wear parts, must be made of strong material.
Set of welding concentrated cleaner should not interfere with operation and easy to repair a.
According to the process operation requirements, set the necessary hole operation, access door and observation hole and the door opening should be tight, close the flexible;
b。
Airtight cover on the need to remove part of the structure should be easy to remove and install.
Attention should be paid to cover air flow movement characteristics in a.
Correct selection of sealing cover form and exhaust point location, to reasonably organization flow, keep the enclosure negative pressure;
b。
Airtight cover a certain space, to buffer air flow, reduce the positive pressure;
c。
Hole operation, access door to avoid the location of the air velocity is higher.
Welding concentrated purifier attention concentrated cleaner exhaust effect and uniformity of mouth section on wind speed.
Design requirements for tank mouth wind speed is not less than 80% of the average wind speed, when the rack at the same time generate heat, so as to prevent dust gas escape from work on the edge, should be on extraction;
When generating heat inside ark, can be in the lower convulsions.
On work mouth section should not be any wind speed is greater than 10% of the average wind speed lower vents should be close to the work surface.
Welding concentration purifier generally located in the workshop or laboratory, cover mouth airflow vulnerable to environmental interference, usually calculated according to the recommended population speed exhaust air volume, and then multiplied by 1.
The safety factor of 1.
Welding associate concentrated cleaner should not be located in numerous locations, near the window or door.
Prevent interference of horizontal airflow.
When cannot set up separate exhaust system, the amount of each system connection cabinet cover should not be too much, the best single set exhaust system.
