回答1:

◆1、空压机的周围环境影响到空压机的散热,比如说空压机离墙或者障碍物过近、空压机附近有其他热源、空压机运行时前门或边门敞开,导致风扇无法形成强气流,这些都会导致空压机环境通风散热状况不良。
◆2、散热器堵塞。当空压机周围环境飞尘较多时,空压机的长期运行就会造成散热器外表黏附一层粉尘或油污,而内部结构也容易因油垢积累而堵塞,影响散热效果。
◆3、滤油器太脏。当压缩机中的滤油器太脏时,阻力油无法按正常流量进入压缩机,压缩机会因冷却润油不足而迅速升温,当进出油压差超过0.18Mpa时就需要更换滤芯。
◆4、冷却油油面过低。当空压机冷机检查时,油面低于检视管下端时应立即进行补充。
◆5、油标号低或是油质差。空压机采用生产厂商的专用压缩机油,用其他低标号或是劣质油时会回黏度及比热达不到标准,从而造成温度过高。
◆6、风扇胶带断裂或者松弛。当胶带断裂时空压机运转5min左右就会因为温度过高而自动停机,如胶带太松会打滑,使风扇转速降低,影响散热,因此需更换或调整风扇胶带的松紧度。
◆7、断油阀失灵。在滤油器与压缩机之间有个断油阀,当断油阀无法开启时因无润滑油及冷却,压缩机启动后温度迅速上升,大约1Min左右就会自动停机。应拆下压缩机主机排气端的温度塞,发现温度塞上干燥无油,亦会有青烟从孔中飘出。打开空压机检修孔,拆下断油阀,用手指轻轻拨动阀杆,看能否前后推动或能否轻松复位。如果拨动或回位困难,则需进一步降断油阀解体。如果阀杆或阀孔有油垢,则需用细砂纸打磨直至能轻松滑动;如果弹簧折断或有异物卡信也会影响阀杆运动,此时需要=更换弹簧或清洗弹簧或弹簧座。
◆8、油气分离器芯太脏。当油气分离器芯太脏时,油因阻力过大而影响循环,造成过热停机。如遇到这种情况,应从加载前后的压差进行判断,当两端压差为开机之初时的3陪或最大压差达到0.1Mpa时,就应该清理或更换油气分离器芯。
◆9、温控器旁通阀处于开启位置。温控器旁通阀在冷机时处于开启位置,温度升高后逐渐关闭。当它失灵后就可能一直处于开启位置,冷却油就从此处而不通过散热器直接回流空压机,所以温度会慢慢升高二导致停机。检修方法与断油阀检修方法相似。
◆10、排气压力过高。当排气压力超过额定压力时,长时间运行就会因压缩机及柴油机负荷过重而升温导致空压机停机。如出现这种情况需要先检查和调节压力阀,然后检查柴油机油门控制系统并排除此故障。

回答2:

螺杆空压机高温首先确认油位是否正常,其次空压机风扇是否正常运行,散热器是否堵塞,(手放在散热器进口及出口是否有温差),温差大就要检查温控了。

回答3:

引起温度高的原因大约有1,缺油或油品变质.2,空气过滤器堵塞 . 3,散热片太脏,影响通风(风冷机). 4,机油过滤器堵塞 .5,温控阀性能不良 .6,主机轴承异常或是螺杆出现问题 .7, 空压系统有漏气,或空压机每分钟产气量小于生产的需气量,。空压机一直在加载。

回答4:

有很多,油位正常吗?冷却器脏不脏?节温器打没打开?等等 挺多的原因

回答5:

温度高只是表象,引起温度高的原因太多啦,就像人发烧一样,得用排除法。先检查过滤系统:空滤、油滤、油分滤芯、断油阀是否堵了;再检查冷却系统:冷却器是否堵了;冷却水量足够吗;恒温阀是否出问题了;检查润滑油位正常吗?检查测温探头和参数显示仪是否正常(可用红外测温仪手动检测证实是否高温)空压房通风状况正常吗?
