Hydraulic oil is very important for the lifting platform. It has the functions of system lubrication, kinetic energy transmission, anti-corrosion and rust prevention, cooling, etc. The quality of the hydraulic oil will affect the hydraulic transmission system of the lifting platform, as well as the operation stability and service life. Shandong Cathay Machinery will expand it in detail for you:
1. Viscosity is a key element of hydraulic oil. Appropriate viscosity can ensure accurate and smooth transmission of power under conditions of changing operating temperature, and can also ensure normal lubrication of hydraulic parts. When the viscosity is too low, it is easy to cause leakage of the hydraulic transmission system, resulting in failure of normal operation. When the viscosity is too high, the transmission efficiency will be reduced, which will cause the hydraulic oil flow rate to slow down and the oil pump discharge to decrease, so that the lifting speed of the lifting platform will also decrease.

Another question, how to judge the quality of hydraulic oil?
The quality of hydraulic oil is mainly identified by its anti-oxidation, anti-foaming properties, anti-wear properties and smell and color:
1. Antioxidant. If you have enough time, you can pack the sample in a transparent plastic bottle, tighten the bottle cap, and put it in the sun for a period of time. In contrast, the function of darkening is not good, and the service life of the oil is shorter. Two different samples can also be heated at the same time and kept at about 150 ℃ for two hours. If the color changes greatly, the quality is not good.
2. Anti-foaming properties. Seal the two sample bottles with the same amount of oil, shake them vigorously for the same time, and observe the defoaming speed of the samples after they are still, and the faster defoaming is better.
3. Anti-wear properties test. Use a friction tester to withstand samples with many weights, and its anti-wear performance is good.
4. smell, color. Generally good oil products have a high degree of base oil refining, light color, light odor, and light color after adding additives. Good oil generally has a very light smell and must be clear, transparent and light yellow in color. If the oil smells pungent, the color is very dark, the surface of the oil is fluorescent green, or the oil is cloudy, it is not a good product.
