    Introduction of important inspection items of explosion-proof chain electric hoist


Description: Explosion-proof chain electric hoist, as a kind of lifting equipment with high safety performance, has been widely used in industrial manufacturing and building construction. But you need to check before using the gourd, let's take a closer look.

As a kind of lifting equipment with high safety performance, explosion-proof electric chain hoist has been widely used in industrial manufacturing and building construction. But you need to check before using the gourd, let's take a closer look.

First, the three steps of inspection of explosion-proof chain electric hoist

Check the voltage

In the first step, we need to check the operating voltage of the chain hoist to ensure that the voltage value is not less than 5% of the rated voltage. Because when the motor starts to start, the torque amplitude is too small, and it needs to consume a lot of electricity to be able to lift the goods. Therefore, sometimes the voltage is too low, which will cause the equipment to fail to start normally.

When checking the equipment voltage, we can use a multimeter and other measuring instruments to measure the relevant voltage value, but ensure the stability of the equipment voltage.

2. Check whether the phase is missing

Short circuit and open circuit of the line will also cause insufficient power supply to the equipment, making the chain hoist equipment unable to operate normally. For this kind of failure we need to carry out a detailed inspection of the circuit board of the device.

When inspecting the circuit board, it is necessary to cut off the power supply of the equipment, otherwise it will not only cause damage to the circuit board but also threaten human life and safety.

3. Check for no power

After completing all the above steps, we need to check the power supply of the device. Generally, a test pen can be used for measurement, and the inaccessible lines need to be repaired in time.

Second, the difference between explosion-proof chain electric hoist and ordinary chain electric hoist

1. Higher safety performance

Compared with ordinary chain electric hoists, explosion-proof electric chain hoists have increased explosion-proof functions, which can effectively ensure the safety of the equipment during use, and have been comprehensively designed in terms of structure, which not only improves its seismic performance, Reduced equipment footprint, making the hoist easier to handle and more flexible in operation.

2.High efficiency

Compared with ordinary chain electric hoists, the explosion-proof electric hoist has a faster lifting speed and a corresponding increase in lifting weight. Explosion-proof electric hoist uses a 2-stage gear design, which can effectively avoid overloading the lifting cargo, and the high-strength lifting chain also makes the operation of the equipment more stable.
