In summer, the normal temperature of hydraulic oil should be controlled below 60 degrees Celsius. As the temperature gradually increases, the temperature of the hydraulic oil of the hydraulic baler ya chuma will also increase. When the temperature reaches 80 degrees or more, due to the difference in thermal expansion coefficient, the oil temperature in the hydraulic components will change abnormally, and the relative spacing and movement between the working components will also be different. When the oil temperature exceeds 60 degrees, the viscosity of the oil decreases, leakage increases, the sliding part of the oil film is damaged, the wear of hydraulic components increases, and the temperature rise speed increases.

Kupanda kwa joto la mafuta ya hydraulic kunaathiriwa na sababu nyingi. Inapatikana kwamba wakati joto la mafuta ya mashine ya hydraulic linaongezeka, watumiaji wanaweza kupata sababu zifuatazo:

  • Uzalishaji wa joto wa baler ya chuma ni mbaya. Mvutano mkubwa wa vumbi kwenye nje ya radiator utasababisha tanki la mafuta kupasha joto, hewa mbaya, na joto la mafuta kupita kiasi; ikiwa kiwango cha kioevu ni kidogo sana, mfumo wa mzunguko wa mafuta hauwezi kufanya kazi, na kusababisha joto la mfumo kupita kiasi.
  • Sehemu za baler ya chuma zimechoka. Mara hydraulic components zikiwa zimechoka, leakage ya ndani itaongezeka, kisha joto litapanda, na unene wa mafuta utapungua, na kusababisha kuongezeka kwa leakage ya ndani, ambayo itaongeza joto la mafuta na kuunda mzunguko mbaya. The
  • Shinikizo la baler ya chuma si sahihi. Ikiwa valve ya kupunguza shinikizo imepangiliwa sana, shinikizo la kuzidi haliwezi kupunguzwa kwa kawaida, ambalo husababisha leakage ya ndani kuongezeka na joto kupanda.
  • Uchaguzi wa mafuta ya hydraulic si sahihi. Uchaguzi usiofaa wa chapa ya mafuta ya hydraulic utahatarisha uendeshaji wa kawaida wa mfumo wa hydraulic.
