Abstract
In the heavy type the automobile change direction the system, for easing the pilot's labor strength, increase a safe stability, applied to take a liquid of have the help machine to press to change direction system broadly.The work condition of the automobile is worse, resulting in the liquid press a system pollution,component to wear away easiest, with the result that the creation break down.But the liquid press the breakdown of the system to haven't easy weaknesses such as check and exclusion etc.s.The check method that uses currently has a logic diagnosis method,the iron table technique method,heat the examination method and uses to overflow to flow the valve examination to break down a method,vibration to measure the method and parameter to measure a method mainly etc..But the logic examine a patient the method request to maintain a personnel to have higher knowledge level;The equipments that the iron table technique method use is more expensive, inconvenience in expansion;Heat the examination method can carry on rough diagraph to the component;Use to overflow to flow the valve examination to break down a method to result in a misdiagnosis easily;The vibration diagraph method will accelerate a component to wear away;The parameter diagraph method is currently to use the most extensive method, but experiment set is the in common use equipments that the parameter measure, but the on trial set of the domestic usage is the on trial set of the function one much, and general press a production factory and graduate school appropriation for the liquid.For satisfying the test request that the liquid presses a pump and the help machine, attain the purpose of the fast diagnosis, we designed that liquid to press to change direction on trial set.
This text pressed an on trial pedestal each zero partses to carry on a detailed calculation and the school pit to the liquid in introducing the background of the topic research and the foundation of the meaning:Pass to draw up towards experimenting the pedestal system principle diagram, explain the work principle of the system and manipulate a method;Pass the calculation to the system pressure,discharge, choose the oil pump,pipeline and valve door;Pass the calculation to deliver the calories to system, make sure the physical volume of the fuel tank and choose heating apparatus with spread a hot machine;Pass to spread a design of move the system to the pump station, choose to keep the strength that the gear cone wheel gear spread to move to combine a school to check stalk.The on trial set that we design synthesized a liquid to press the pump,the help machine and liquid to press the function that the valve experiments a pedestal, coming to a the purpose that a machine uses much.Experiment the set adoption to reduce expenses to add to carry a way to match that system originally in low pressure,the request of the small discharge, test simple,dependable.
