About the explosion-proof box maintenance knowledge skills introduction

The explosion-proof box provides us with a safe operating environment in our production, avoiding unnecessary safety accidents, but the maintenance of the equipment is also a very important part. Proper maintenance and maintenance can greatly extend the working hours of the equipment. It is necessary to confirm that the explosion-proof structure type, explosion-proof grade or category, temperature or temperature grade meets the new conditions. For the maintenance of the explosion-proof box, the following is a brief introduction.

When most electrical equipment is installed in the same type of environment, periodic inspections can also be carried out in the form of sampling inspections. At this point, in addition to the inspection cycle, the number of inspections should also be considered. However, at least a comprehensive Visual inspection. When re-installing the electrical equipment explosion-proof power distribution box, check whether it can guarantee its original explosion-proof performance. The type of inspection, the initial inspection must record the preliminary inspection results. Regular inspection, visual inspection or simple Inspection. According to the results of visual inspection or simple inspection, accurate inspection can be carried out.

The degree of inspection and the inspection cycle shall be determined according to the type of equipment, the manufacturer's technical data such as aging, aging factors, the type of hazardous location and the results of the final inspection. For electrical equipment, complete sets of equipment and environments similar to explosion-proof distribution boxes To determine the degree of persistence and periodicity, we can learn from the experience of other similar equipment, and we are determined to adhere to the plan. The periodic inspection period must not exceed 3 years. All routine inspections must be recorded. The sampling inspection is the use of electrical equipment, according to a certain percentage of the total number. Sampling inspection of each machine. Sampling inspection can be carried out by visual inspection, simple inspection or precision inspection.

The quantity of the sample and the content of the test can be determined according to the purpose of the test. All sample tests must be recorded. The sampling is to vent environmental conditions, vibration, potential design defects, etc., and the sampling test can not find unpredictable defects. Such as loose connectors. Due to the harsh conditions of use of mobile electrical equipment, especially vulnerable to damage.

Therefore, it is necessary to carry out a precise inspection cycle, and at least one precision inspection should be carried out every year to confirm whether the mobile electrical equipment, the moving wires and the connecting parts of the two are damaged. It is necessary to record accurate inspection results. Explosion-proof distribution box equipment in dangerous places Users are required to check regularly, although it is a large task, but it is worthwhile to ensure the protection of on-site operators and company assets than the dangers that can be passed.
