Description
Technical field
The invention belongs to industrial lubricant field, particularly environmental-friendly track controllable wagon retarders working fluid composite.
Background technology
Deceleration top is a kind of railway deceleration device that extra power is not required, and is realized using hydraulic principle to travelled by vehicle speed
The automatic identification of degree and control.Deceleration top is invented by Englishman earliest, in Hump at marshalling stations governing system, carrying out vehicle
A kind of hydraulic test of speed control.During work, it is not necessary to external energy come make rolling stock slow down device.Liquid can be utilized
Principle is pressed to realize to Vehicle Speed automatic identification and control.This deceleration top is installed in the side of track, when through over-subtraction
When the car speed on speed top is higher than setting, deceleration top can apply brake force to vehicle and make vehicle deceleration.
Its operation principle is：When vehicle is with less than the sliding oil cylinder of defined critical speed pressure deceleration top, subtract
Substantially deceleration damping action is not played to vehicle in speed top；If vehicle is with the sliding oil cylinder higher than defined critical speed pressure deceleration top
During body, fluid is with certain pressure flows to the cavity of resorption of oil cylinder and consumes work(, so as to act damping of slowing down to vehicle.
And controllable wagon retarders are a kind of controllable deceleration tops used, can be needed to make it play decelerating effect according to shunting service
Or do not play decelerating effect.This kind of controllable wagon retarders can be treated with a certain discrimination every in the case where track is changed and need at least have two seconds spaced apart conditions
One car, i.e., be controlled good rolling car by speed, and hard rolling car is passed through without control.It is this kind of to be controlled or not
The instruction of control can be sent by computer after the weight of comprehensive descision vehicle, by speed and walking resistance.Certainly
It can control manually.Therefore the quality of its hydraulic oil used will directly affect service efficiency and the service life of controllable wagon retarders.Liquid
Pressure oil should have good low temperature flow, viscosity-temperature characteristics, bearing capacity, wear resistence, rust-preventing characteristic, oxidation stability and emulsion resistance
Property.
The content of the invention
The technical problem to be solved in the present invention is to provide it is a kind of have good low temperature flow, viscosity-temperature characteristics, bearing capacity,
Wear resistence, rust-preventing characteristic, leakproofness, detergency, the environmental-friendly track controllable wagon retarders work of oxidation stability and resistance to emulsion
Make liquid composition.
The present invention adopts the following technical scheme that solution above-mentioned technical problem：
Environmental-friendly track controllable wagon retarders working fluid composite, using oil based on poly-internal-olefins, coordinates a variety of adds
