The Engineering Research Of Controling Hydraulic System Oil Temperature For Resin Sand Modelling Equipment

Our company introduce resin sand production line from Italy, model line , make core line , pour line PLC programme-controlled automatic assembly line, the transmission relates to being very extensive, among them rely mainly on hydraulic transmission, the systematic operation state of hydraulic pressure influences the normal work of the whole production line directly, this text will be with the typical apparatus of sand model of resin - Turn machine of mould got up example , launch this thesis argumentation of topic , to influence hydraulic a great deal of troubles of system analyze and describe, and has carried on systematic analysis on the warm and too high problem of systematic oil of the hydraulic pressure, summarize some effectual trouble treating methods.On solving the systematic oil of hydraulic pressure warmly and too high , mainly proceed from the reality, analyze in terms of whole system , use a large number of calculation data to explain the warm and too high basic reason of oil, i.e. systematic oneself is unable to mediate the thermal balance in the working course, that is to say the heat that produces systematically in the working course should be higher than its heat that send out, including hot exchange of cooler , surrounding environment , fuel tank and oil pipe and external air distributed ,etc..On the other hand, the systematic trouble of hydraulic pressure relates to the following factor too: Including systematic to design unreasonable by itself, initial designed capacity low can demand , system worked now to meet maintain , maintain bad operating against regulations.In this text, on solving the systematic oil of hydraulic pressure warmly and too high , have adopted the industrial liquid refrigeration apparatus - hydraulic cooler, because should refrigerate the apparatus and have intellectual controlling parts , can control hydraulic oil temperature within certain range , so, to calculated and can not reach the system of thermal balancing , use it to cool by force, save time , convenient, a kind of effectual warm control method of oil.
