5. Equipment maintenance engineering company: power equipment repair, large-scale unit maintenance projects, mobile operations, can complete oil purification on site, without the need to extract oil and transport it to the factory for processing, greatly shortening the maintenance period.

This equipment relies on the principle of vacuum separation. After the oil enters the vacuum tank, under negative pressure and heating, the dissolved water in the oil vaporizes and gas precipitates, and the water vapor and gas are extracted by the vacuum pump; After degassing and dehydration, the oil undergoes fine filtration to remove solid impurities, completing the entire purification process. The core advantage of this device is that it can remove dissolved water inside the oil, which is a function that ordinary oil filtration carts and coalescence oil filters cannot achieve.

Core competitive advantages of the product

1. Vacuum deep purification can remove dissolved water and gas: Ordinary oil filtration equipment can only remove free water, ZLYC relies on a high vacuum system to separate the invisible dissolved water and gas in the oil, significantly improving the breakdown voltage of insulation oil and meeting the strict standards of power equipment.

Frequently Asked Questions (FAQ)

FAQ1: What is the biggest difference between ZLYC vacuum oil filter and LYC-J coalescence dehydration oil filter?

Answer: The LYC-J coalescing oil filter is suitable for removing free water and mildly emulsified water from oil, but cannot remove dissolved water; ZLYC vacuum oil filter relies on a vacuum system to remove dissolved water and gas from oil, improve the breakdown voltage of insulation oil, and is commonly used for deep purification of transformer insulation oil, with higher requirements for oil quality indicators.

FAQ2: Can ZLYC vacuum oil filter be used for vacuum oil injection of transformers?

Answer: Sure. The ZLYC vacuum oil filter is equipped with a high vacuum system. In addition to purifying the oil, it can directly vacuum the transformer and complete the vacuum oil injection operation. It is a commonly used equipment for power transformer maintenance.

FAQ3: Can the device work continuously for a long time?

Answer: Sure. The equipment is equipped with stable vacuum pump units, oil pumps, and a complete protection system, supporting long-term continuous circulation purification, suitable for large transformer oil treatment and long-term oil filtration operations of the machine.

FAQ4: Do all levels of filter elements need to be replaced together?

Answer: It does not need to be replaced at the same time. Coarse filtration mainly intercepts large particle impurities, resulting in faster blockage; The backend fine filter has a longer service life. By relying on the pressure difference of the pressure gauge to determine the status of the filter element, the corresponding filter element can be replaced separately for each level of pressure difference exceeding the standard, saving consumable costs.

FAQ5: Will there be a decrease in vacuum degree during the operation of the equipment?

Answer: The equipment has undergone strict vacuum pressure testing before leaving the factory, and the vacuum degree is stable under normal sealing conditions. If the sealing components are aging or the filter element is damaged, it will cause a decrease in vacuum degree. Regular inspection of the sealing components is sufficient.
