Excellent product characteristics
1.Flame retardant performance
Sencro water glycol fire resistant hydraulic fluid is not absolutely non-flammable, but it will not burn under most conditions.
2.Wear resistance
In many equipments using water glycol, a large number of use cases have confirmed that this fluid has good anti-wear properties. During the product development and production process, Sencro water glycol fire resistant hydraulic fluids are subjected to pump bench tests. In particular, Vickers vane pump experiments are carried out.
Pump Model | Vickers V105 C |
Test time | 250 Hours |
pressure | 105 Bar |
Liquid temperature | 45℃ |
Pump revolutions | 1500 RPM |
Ring wear | 3-25 MG |
Leaf damage | 1-7 MG |
Wear data shows that Sencro hydraulic fluid has excellent anti-wear performance. In the same experiment, the wear amount shown by mineral oil-based hydraulic oil is not significantly different from that of Sencro hydraulic fluid .
3. Viscosity/temperature characteristics
Sencro hydraulic fluid , like mineral oil, has a smaller change in viscosity with temperature changes. This is commonly referred to as having a high viscosity index. This characteristic is very important for maintaining the working stability of the hydraulic system.
4. Compatibility of metal and non-metal materials
Since Sencro glycol hydraulic fluid contains gas-liquid phase rust inhibitors, it can protect metal materials in the hydraulic system that have long-term contact with Sencro glycol hydraulic fluid from corrosion. It should be noted that since the content of gas-phase rust inhibitors must be controlled within a certain range, it is difficult to avoid rust on the inner surface of the tank cap due to the effect of attached condensed water. Therefore, it is recommended that the tank cap be made of stainless steel, or that the surface of the tank cap be treated with rust prevention by other methods. When selecting the material of the filter element, you should also pay attention to the compatibility issue. All materials that are compatible with water, such as polyester fiber, specially treated celluloid fiber, glass fiber, and wire mesh, can be used in water glycol flame-retardant hydraulic fluid . If it is a paper filter element, it needs to be treated with phenolic resin before it can be used.
