Harm of dowty retarder oil pollution

Dowty retarder belongs to hydraulic machinery, whether it can work normally, in addition to the factors of dowty retarder system design, hydraulic components manufacturing and daily maintenance, how to maintain the cleanliness of hydraulic oil and instrument oil is a very important factor. It is very important to the sensitivity, stability, reliability and life of dowty retarder. The contamination of oil will affect the normal operation of the dowty retarder and the premature wear of the components, resulting in dowty retarder failure.

Danger of oil pollution to dowty retarder

The specific hazards of oil pollution to dowty retarder are as follows: (1) Pollution will make the speed valve, pressure valve, return valve and damping hole strained, causing the working pressure and speed change of dowty retarder, unstable and insensitive.

(2) Pollutants will accelerate the wear of piston assembly parts, cause internal leakage and reduce brake work.

(3) Pollutants will accelerate the damage of seals and the surface of sliding oil cylinder or piston rod, which will cause oil and gas leakage of dowty retarder and damage the surface of piston rod, which will cause oil and gas leakage of retarder and cause topping or damage.
