挖掘机:液压油泵有响声是不是出现故障了!

日期:2020-09-24   来源:http://www.dybocheng.com
1)挖机的液压油泵排气量比别的型号更大。
1) The displacement of hydraulic oil pump of excavator is larger than other models.
(2)液压油泵安裝室的侧门未密封性,有排热孔,和密闭式的较为有来讲有一定的噪声。
(2) The side door of the hydraulic oil pump installation room is not sealed, and there is a heat vent, which has a certain noise compared with the sealed one.

在第二选中,输油管颤动还应留意:
In the second selection, attention should also be paid to pipeline vibration:
(1)输油管颤动是不是是由于工作压力变化大,不稳定造成的。
(1) Whether the vibration of oil pipeline is caused by the change of working pressure and instability.
(2)主导过滤芯有阻塞的状况,应常常清理,防止阻塞。
(2) If the main filter element is blocked, it should be cleaned frequently to prevent blockage.
(3)查验安全性继电器电源开关是不是转换出现异常。
(3) Check whether the power switch of safety relay is abnormal.
假如明确液压油泵声响异常,需从下列层面考虑到:
If the sound of hydraulic oil pump is abnormal, the following aspects should be considered:
1.是不是应用的真品齿轮油及其液压机回液压油滤芯。
1. Is it a genuine gear oil and its hydraulic press return hydraulic oil filter element.
2.齿轮油环境污染比较严重;挖机必须按时开展维护保养,非常是常常开展粉碎工作也是要留意齿轮油的环境污染状况,提议一般5000钟头拆换应用一次齿轮油,打粉碎600钟头就应开展拆换,因为油的环境污染,难以实现需有的润化及维护功效。

2. The environmental pollution of gear oil is relatively serious; excavators must carry out maintenance on time, and grinding work is very often carried out. It is also necessary to pay attention to the environmental pollution of gear oil. It is suggested that gear oil should be removed and replaced once every 5000 hours, and it should be removed and replaced after 600 hours of grinding. Because of the environmental pollution of the oil, it is difficult to achieve the required lubrication and maintenance effect.
3.燃油管不顺畅,很有可能为齿轮油不够或吸液压油滤芯阻塞,吸进气体后导致对泵的损害。
3. If the fuel pipe is not smooth, it is likely that the gear oil is insufficient or the suction pressure oil filter element is blocked, which may cause damage to the pump after gas is sucked in.
4.液压油泵安裝精密度不足。
4. The installation precision of hydraulic oil pump is insufficient.
5.控制器和继电器一部分工作中异常,呼市挖掘机租赁不可以将液压油泵的斜盘视角调节到必须的视角,造成液压油泵輸出的总流量不可以与必须的总流量配对,导致泵的响声。
5. Some of the controllers and relays work abnormally. It is not allowed to adjust the swash plate angle of the hydraulic oil pump to the necessary angle of view for the lease of Hohhot excavator, resulting in the total flow of the hydraulic oil pump not matching with the necessary total flow, resulting in the pump noise.
6.因为不标准工作或过载运作,导致对液压传动系统冲击性过大,减压阀造成泄压声。
6. Because of nonstandard work or overload operation, the impact on the hydraulic transmission system is too large, and the pressure relief valve causes pressure relief sound.
7.热机時间不够时就开展工作,热机不够会导致齿轮油黏度较高,危害其流通性,导致对泵的冲击性过大。
7. If the heat engine time is not enough, it will lead to the high viscosity of gear oil, which will damage its liquidity and cause the impact on the pump to be too large.
