小型挖掘机液压油温度高怎么?

日期:2023-10-19   来源:http://www.dyqicheng.com/
1.液压油散热器内部堵塞或散热器外观太脏,影响散热效果(即散热器不能工作)。
1. The internal blockage or dirty appearance of the hydraulic oil radiator can affect the heat dissipation effect (i.e. the radiator cannot work).
2.液压油箱缺少液压油或液压油太脏,液压滤芯堵塞,导致温度过高(如果长时间不保养,液压油质量会下降,循环性能会变差,产生过多的热能)。
2. The hydraulic oil tank lacks hydraulic oil or the hydraulic oil is too dirty, the hydraulic filter element is blocked, resulting in high temperature (if not maintained for a long time, the quality of the hydraulic oil will decrease, the circulation performance will deteriorate, and excessive heat energy will be generated).
3、液压系统中液压油泄漏过多,导致液压油泄漏过多,各阀芯液压件磨损间隙过大,产生大量热量导致温度过高;
3. Excessive hydraulic oil leakage in the hydraulic system leads to excessive hydraulic oil leakage, and the wear clearance of hydraulic components in each valve core is too large, generating a large amount of heat and causing excessive temperature;
4.回油单向阀损坏(弹簧损坏或阀卡死),导致回油无阻力或未通过散热器直接回油;

4. The return check valve is damaged (spring damaged or valve stuck), resulting in no resistance to return oil or direct return oil without passing through the radiator;
5.由于电路系统故障、传感器或电路问题导致的误报;
5. False alarms caused by circuit system failures, sensor or circuit issues;
6.液压泵内部泄漏过多,工作装置动作缓慢,导致温度过高;
6. Excessive internal leakage in the hydraulic pump, slow operation of the working device, resulting in excessive temperature;
7.发动机功率不足与液压泵不匹配,液压泵供油不足增加液压系统负荷,增加工作装置阻力,形成高温;
7. Insufficient engine power does not match the hydraulic pump, and insufficient oil supply from the hydraulic pump increases the load on the hydraulic system, increases the resistance of the working device, and forms high temperatures;
8.对于大型小型挖掘机,液压系统具有单独的液压风扇马达、液压风扇泵和液压风扇电磁阀。这三个部件的损坏将导致液压温度过高。
For large and small excavators, the hydraulic system has separate hydraulic fan motors, hydraulic fan pumps, and hydraulic fan solenoid valves. The damage to these three components will cause the hydraulic temperature to be too high.
小型挖掘机的类型分类
Classification of Types of Small Excavators
1.根据驱动方式,有内燃机驱动小型挖掘机和电动小型挖掘机。电动小型挖掘机主要用于高原缺氧、地下矿山等易燃易爆场所。
1. According to the driving method, there are internal combustion engine driven small excavators and electric small excavators. Electric small excavators are mainly used in flammable and explosive places such as high-altitude hypoxia and underground mines.
2.小型挖掘机按行走方式分为履带式小型挖掘机和轮式小型挖掘机。
2. Small excavators are divided into tracked small excavators and wheeled small excavators according to their walking mode.
3.小型挖掘机按传动方式分为液压小型挖掘机和机械小型挖掘机。机械小型挖掘机主要用于一些大型矿山。
3. Small excavators are divided into hydraulic small excavators and mechanical small excavators according to their transmission methods. Mechanical small excavators are mainly used in some large mines.
4.小型挖掘机按用途可分为通用小型挖掘机、矿用小型挖掘机、船用小型挖掘机、专用小型挖掘机等不同类别。
4. Small excavators can be divided into different categories according to their purpose, such as general small excavators, mining small excavators, marine small excavators, and specialized small excavators.
5.小型挖掘机按铲斗分为前铲小型挖掘机和反铲小型挖掘机。
5. Small excavators are divided into front shovel small excavators and backhoe small excavators according to their buckets.
