Sand dust test chamber characteristics and maintenance

The sand dust test chamber is suitable for dustproof and dust proof tests on various auto parts. The test parts include car lights, meters, electrical dust covers, steering systems, door locks, etc., as well as the sealability of the tested products. The time controller of the sand dust chamber can show the time of the equipment operation. If the equipment fails, it can also show the specific time when the equipment fails. This has played a big role in maintenance.

If you do not use it for a long time, clean the inner wall and keep it dry to facilitate the next experiment.


In order to stabilize the performance of sand and dust chamber holders, daily inspections and maintenance must be done :

1. When the test box hears an abnormal sound during operation, it should immediately stop the inspection, find out the reason and troubleshoot before continuing to work; must add oil regularly;

2, to avoid external forces hit the box, mobile equipment, to avoid falling, impact, scratch, vibration, extrusion equipment;

3, avoid tilted placement;

4, check the circuit control system before starting;

5, the power cord is properly connected according to requirements, confirm the grounding;

6. Prohibit corrosive articles from contacting equipment;

7. Install a ventilation fan in the laboratory and keep it ventilated and dry;

8, after the end of the test, the sample should be removed, the equipment inside the box clean, cut off the power of the machine;

9. After use, cover the plastic cover to avoid dust erosion;

10. Non-professionals are prohibited from operating this equipment to avoid danger.

6. Central Fume Extraction System

1) Cantilever type fume extraction system

Cantilever dust removal can be used for manual welding conditions where the work stations are evenly distributed and the span is small. The smoke and dust generated by each welding station can be effectively absorbed at the dust generation point, and will not pollute other parts of the workshop. The skeleton of the suction arm is similar to a human arm and can hover in a space within a certain length. The outer layer of the suction arm is a temperature-resistant hose, which not only prevents the hose from being burned by sparks, but also ensures the flexibility of the movement of the suction arm. A unique rotating structure is designed on the position of the Suction Hood to ensure that the suction hood can be aligned with the welding position in any orientation, so that the suction arm can effectively capture the smoke and dust generated during the welding process. The advantage of the suction arm capture is that it can be close to the place where the smoke is generated, and the collection effect is better.

2) Hood suction type fume extraction system

Cantilever dust removal can be used for manual welding conditions where the work stations are evenly distributed and the span is small. The smoke and dust generated by each welding station can be effectively absorbed at the dust generation point, and will not pollute other parts of the workshop. The skeleton of the suction arm is similar to a human arm and can hover in a space within a certain length. The outer layer of the suction arm is a temperature-resistant hose, which not only prevents the hose from being burned by sparks, but also ensures the flexibility of the movement of the suction arm. A unique rotating structure is designed on the position of the suction hood to ensure that the suction hood can be aligned with the welding position in any orientation, so that the suction arm can effectively capture the smoke and dust generated during the welding process. The advantage of the suction arm capture is that it can be close to the place where the smoke is generated, and the collection effect is better.

3) Room tupe fume extraction system

Room-type dust removal is suitable for the purification of fumes and smoke generated during the production of automated equipment, such as welding robots, welding machines, grinding, grinding and polishing of metal and plastic parts, drilling, thermal processing, cutting and crushing, stone processing, powder packaging, solid particles and various dusts and fumes produced by mixing and processing.

For working conditions such as robot automatic welding, circular seam and longitudinal seam welding, the smoke and dust purifier is installed with the robot workstation, so that the workstation has its own dust removal function. The fume and smoke are effectively collected through equipment components such as pipes and dust hoods. The room-type design prevents the volatilization and diffusion of smoke to keep the air in the workshop clean.

The working conditions with moderate welding workpieces and large amounts of dust and smoke are suitable for room-type treatment solutions. The room type centralized dust dedusting solution is divided into side suction and top suction method dust collecting ways. The appropriate solution can be designed according to the site conditions and treatment goals.

4) Blow suction type fume extraction system

Blow-suction type dust removal solution is a ventilation air flow composed of blown air and inhaled air flow. Therefore, it is a dust removal method that can effectively control the spread of pollution sources. This dust removal method is installing exhaust inlets on two-span center column or single-span side column (wall) and air outlets on the opposite wall column to form a circulating air flow to drive the smoke and dust into the purification machine, consequently performing overall dust removal and purification in the workshop. This system occupies a small area and has obvious purification effect, which is suitable for the purification of smoke and smoke in more complex production workshops.
