In the design of explosion-proof electric hoists, multiple parts need to have high sensitivity to ensure their explosion-proof performance. Here are some key areas that may require high sensitivity:

Explosion proof shell: This is an important part of the explosion-proof electric hoist, and its design should have high sensitivity to ensure that it can quickly and effectively prevent the ignition of explosive gas mixtures outside in the event of internal sparks or high temperatures.

Intrinsically safe components: Intrinsically safe equipment prevents the ignition of explosive gas mixtures by limiting energy levels. Therefore, these components need to have high sensitivity to ensure that the energy generated during normal operation and fault conditions is lower than the ignition energy.

Positive pressure casing: This type of equipment needs to maintain internal pressure higher than external pressure to prevent external explosive gas mixtures from entering the interior of the equipment. Therefore, the pressure detection system of the positive pressure casing needs to have high sensitivity to ensure timely detection of pressure changes and corresponding adjustments.

Sealing components: certain parts of the equipment are sealed with sealing materials to prevent explosive gas mixtures from entering the interior of the equipment and to prevent internal ignition sources from spreading to the outside. The sealing and integrity of the sealing material are crucial for its explosion-proof performance, therefore a highly sensitive detection system is needed to monitor its condition.

Anti dust ignition housing: The housing of such equipment needs to prevent dust from entering the interior of the equipment and prevent ignition sources from igniting dust. Therefore, the sealing and integrity testing of the casing needs to have high sensitivity.

In addition, the control system and sensors of explosion-proof electric hoists also need to have high sensitivity to ensure that they can respond quickly and take corresponding safety measures in case of abnormal situations.

Overall, multiple parts of the explosion-proof electric hoist need to have high sensitivity to ensure its explosion-proof performance. However, the specific areas that require high sensitivity may vary depending on different explosion-proof levels, application environments, and equipment types. Therefore, in practical applications, comprehensive evaluation and selection should be carried out based on specific situations.
