When evaluating the quality issues of explosion-proof electric hoists, it is necessary to focus on their design, manufacturing, inspection, and use processes. The following is a specific analysis:

Design link

The design of explosion-proof electric hoists must strictly comply with explosion-proof standards, such as motors, electrical components, etc., which must have explosion-proof performance and be supplemented with corresponding mechanical explosion-proof measures. If the design does not comply with the specifications, it may result in ineffective prevention of explosions caused by electric sparks or heat in practical use.

Manufacturing process

During the manufacturing process, the quality of purchased parts, external processing, and external supporting components must be strictly controlled. For example, if the quality of small components such as spring washers does not meet the standards, it may also cause serious accidents. In addition, assembly quality is equally critical, and if details such as bolt tightening are not handled properly, they can become potential safety hazards.

Inspection process

Before leaving the factory, explosion-proof electric hoists need to undergo strict tests and inspections, including type tests, routine tests, medium tests, sampling tests, life tests, and tolerance tests. These experiments aim to verify whether the design requirements comply with specifications, ensure that the device or equipment meets certain standards, and evaluate the product's lifespan characteristics. If there are omissions in the inspection process, it may lead to unqualified products entering the market.

utilize

When using explosion-proof electric hoists, users need to regularly check the operation of each link and part, promptly repair any abnormalities, and eliminate safety hazards. For example, it is necessary to regularly check the reliability of the motor connection fixing bolts to prevent equipment failure or accidents caused by loose bolts.
