The air supply oil pump power distribution room switch cabinet to the control cable of the field control cabinet is short-circuited to the grounding wire, so that the induced voltage of the control circuit is reduced, and the normal operation of the air compressor oil pump can be temporarily guaranteed. Once the air compressor and the oil pump motor are shut down, the control loop transformation is implemented immediately. It is only a matter of time to solve this problem. So far, this technical breakthrough has been successful. At the same time, the plant electrical maintenance team also organized the learning and technical digestion of the new schematic diagram of the oil pump, and predicted and analyzed the loop fault to accelerate the response mechanism and processing speed of the oil pump circuit failure.

After optimizing the control circuit of the 1# air compressor A and B oil pumps, the electrical control is more reasonable and reliable, which greatly reduces the maintenance pressure, and the nitrogen production of the plant is further guaranteed. The 2# air compressor oil pump control circuit will also be rebuilt in May 2012. It has been in operation for more than three months, and the air compressor unit is running smoothly. This has completely eliminated the hidden dangers of such equipment left by the air separation air compressor system. The stable production of the plant provides a strong guarantee.

Single Phase Electric Chain Hoist

Our single-phase electric chain hoist is based on the HHBB Electric Chain Hoist by adding a frequency converter to achieve single-phase electric voltage. It can be widely used in factories, mines, docks, shops, warehouses and other places, as well as supporting various equipment on various modern assembly lines.
