Hydraulic decoilers are essential equipment in industrial settings that require the handling of large rolls of materials. However, they have inherent shortcomings that can lead to increased costs and production accidents. One of the most commonly used optional equipment for hydraulic decoilers is the hydraulic expansion device. Its main functions are to replace manual hand-operated expansion and contraction of the roll and to spray lubricating oil onto the core shaft gears and bearings of the hydraulic decoiler. The hydraulic expansion device ensures cleaning, cooling, and lubrication effects, which guarantee the normal operation and service life of the hydraulic decoiler’s bearings and gears, ensuring stable long-term operation.
However, the entire hydraulic closed-loop system of the hydraulic decoiler needs to ensure moderate flow rate, unobstructed sealing and piping systems to ensure the stable and normal operation of the hydraulic decoiler. Insufficient lubricating oil can lead to rapid damage to bearings or gears, resulting in increased costs or production accidents. If the oil return is not smooth, oil leakage and environmental pollution can occur, wasting resources and increasing costs. These two issues are common problems with hydraulic decoilers on the market.
Henli, a leader in the industry, has made a series of improvements to the hydraulic system to fundamentally solve the shortcomings of the hydraulic decoiler. One of the most significant improvements is drilling lubricating oil discharge holes in the lower part of the end cover of the hydraulic system, connecting them to the gearbox through a return pipeline. This innovative technology allows the excess grease accumulated in the grease gathering area to discharge through the lubricating oil discharge hole and circulate back to the gearbox through the return pipeline of the circulating pump. This solves the oil leakage problem from the root cause, ensures the stable operation of the lubricating oil lubrication system, and improves the service life of bearings, addressing environmental pollution and resource waste issues.
The benefits of Henli’s hydraulic decoiler technology compared with existing technology are numerous, and they include:
1.A return oil hole has been added below the bearing end cover, allowing a large amount of lubricating oil accumulated at the skeleton seal to flow back to the gearbox through the return oil hole, solving the problem of poor oil return and oil leakage from the skeleton oil seal. It also facilitates daily inspection and maintenance of the hydraulic decoiler.
2.The oil leakage problem has been solved from the root cause, ensuring the stable operation of the lubrication system, improving the service life of the hydraulic decoiler bearings, and addressing environmental pollution and resource waste issues.
3. large amount of lubricating oil accumulated at the skeleton seal flows back to the oil tank through the return oil hole, greatly reducing the requirements for skeleton seal performance, and significantly reducing the amount of skeleton seals used.
4.The need for workers to frequently adjust oil volume, process oil-contaminated equipment, and replace skeleton seals has been eliminated, reducing labor intensity.
In conclusion, Henli’s innovative technology has significantly improved the performance and functionality of hydraulic decoilers. Its innovative hydraulic system has solved the common problems associated with hydraulic decoilers, such as poor oil return and oil leakage, environmental pollution, and resource waste. This innovative technology ensures stable operation, improves the service life of the hydraulic decoiler bearings, and reduces labor intensity. Henli’s hydraulic decoiler technology is undoubtedly the way forward for businesses in the industry.
