1. The polyurethane hose has stable performance, anti-wear, anti-aging, and is not easy to be corroded and polluted. It has strong anti-pollution ability and its service life is 2 ~ 3 times that of ordinary rubber hose. Polyurethane has a stable molecular structure, is not easy to react with other substances, has strong anti-erosion ability, prevents the oil leakage phenomenon caused by oil corrosion, thus extends the service life, has strong anti-pollution ability, even if there is oil on the surface, shine like new.
2. Light weight, small bending radius, convenient for design and installation. Polyurethane enhance hose small bending radius, it is the same specification of the rubber hose 2/3 ~ 1/2, convenient for designers to streamline design, can be less filter assembly parts of the test limit and reduce the number of joint, so as to reduce the assembly work and to reduce the risk of the oil leakage, pu reinforced hose light weight, two-thirds of steel tube is the same specification, reduce the labor intensity of handling and assembly, thus improving the working efficiency, reduce the cost.
3. Low pressure loss of polyurethane hoses. Hose assembly can be very good to streamline design, reduced as "steel - flexible combination" pipe elbow, joint and caused by mutations in the cross section flow direction and drastic changes in size, thereby preventing due to formation of vortex and flow of local pressure loss, and the hose wall smooth, on-way resistance coefficient is small, also can effectively prevent the pressure loss is converted into heat energy power steering system caused by the oil temperature rise, increased leakage of unhealthy phenomenon.
4. The polyurethane hose has strong compressive strength, and its impact resistance is 30% higher than that of the high-pressure hose. Due to its high compressive strength and high impact toughness, it can make up for the shortage of the hose and steel pipe, and reduce the vibration caused by impact.
5, the working temperature adaptation is strong, can be in - 40 ℃ ~ + 100 ℃ temperature range of normal use. After the hose assembly is installed, the hose itself can be used for thermal compensation to offset thermal stress.
6. The product is non-toxic, tasteless, pollution-free, safe and reliable in handling and storage. Polyurethane reinforced hose is non-toxic and odor-free and will not contaminate items stored with it. The product can be stored for a long time without rust, thus preventing hydraulic oil pollution and ensuring the normal operation of the hydraulic system.
