    山东装载机工作环境温度高在炎热夏季连续工作,加之冷却效果差或散热不良,造成机器发热量大于散热量,使油温过高。

    1、山东装载机工作环境温度高在炎热夏季连续工作,加之冷却效果差或散热不良,造成机器发热量大于散热量,使油温过高。
    Shandong loader working environment of high temperature Zaiyan hot summer continuous work, coupled with poor cooling effect or bad heat caused by the machine, heat is greater than that of high temperature heat dissipating capacity. 

    2、山东装载机连续长时间在高压大功率下工作,溢流阀频繁开启,液压系统中油路和元件因长时间高压卸荷而使油液升温。
    Shandong loader working for a long time in high power, relief valve open frequently, the hydraulic system oil road and components for a long time and high pressure unloading oil heating. 

    3、山东装载机液压泵是产生热量的主要元件。液压泵转速高,排油压力高,工作环境恶劣,油液污染、油液选用不合规定或油液过少,都可造成泵损、泄漏。泵内泄漏可使其功率损失增大,磨损严重。油液中侵入空气后易于压缩,可造成泵干磨。液压泵内长时间的泄漏、干磨或压缩厉害, 必然发热,引起油液升温,造成系统发热。
    Shandong loader hydraulic pump is the main component of heat generation. High speed hydraulic pump, oil discharge pressure is high, the working environment is bad, oil pollution, oil selection is not specified or too little oil, can cause the pump damage, leakage. Pump leakage can increase the power loss, wear and tear. After the oil in the air is easy to compress, can cause pump dry mill. Hydraulic pump for a long time the leak, dry grinding or compression, the inevitable heat, causing oil temperature rise, causing the system fever.
