Many units now add a benefit to conduct a physical examination once a year for employees to facilitate timely understanding of physical conditions. The same is true of explosion -proof electric gourds. Seven necessary "physical examinations" need to be performed after installation.

Check item 1: Whether the connection of the electrical line is correct and reliable.

Check the project 2: Whether the electrical devices of explosion -proof electric gourds meet the current type and working voltage of the installation location.

Check items 3: Whether the limiter is flexible and reliable.

Checking items 4: The lifting limit switch of the lifting limit switch should check whether the position of the limit switch is consistent with the direction of the uplifting motor, otherwise the wiring should be changed.

Check items 5: Whether all lubrication parts have been lubricated and lubricating oil are added.

Checking items 6: The shell bolts of all explosion -proof parts must be tightened and reliable one by one.

Check the project 7: When the line is powered on, check whether the manipulation direction of the explosion -proof control button is consistent with the movement direction of explosion -proof electric gourds. The above is the seven necessary "physical examination" items performed after the installation of explosion -proof electric gourds. Effectively prevent explosion -proof electric gourd failure.
