开山空压机的运用者们必定有遇到过主机或电机过载而停机的问题,不要担忧,鞍山市兴盛空压机秒速时时彩为你们分忧解难。

The operators of Kaishan Air Compressor must have encountered the problem of the main engine or motor overload and shutdown. Don't worry, Anshan Xingsheng Air Compressor Co., Ltd. will share your worries and solve your difficulties.



一、电压太低:

First, the voltage is too low:



一般的开山空压机额外工作压力为380V,上下答应起浮在5%左右。这里所说的电压是机器正常工作的电压,因为许多工地上(工厂电压供给比较安稳一般不会有这种情况)变压器比较小,设备没有开的时分电压有400V,可是设备一开电压就掉到350V,正常工作起来电压只要360V,短期运用问题不大,假设长时间运用,势必对电器系统构成极大的损伤。

The additional working pressure of the general hill-opening air compressor is 380V, and the upper and lower promises to float at about 5%. The voltage mentioned here is the normal working voltage of the machine, because the transformer is relatively small on many construction sites (the factory voltage supply is relatively stable, generally does not have this situation) and the time voltage when the equipment is not open is 400 V, but when the equipment is open, the voltage drops to 350 V. The normal working voltage is only 360V. The short-term operation is not a big problem. Assuming long-term operation, it is bound to be applied to the electrical system. It constitutes great damage.



二、开山空压机机组压力逾越额外压力:

2. The pressure of the air compressor unit exceeds the additional pressure.



比如0.7MPa的机器,实践压力抵达0.75MPa,就简单出现过载现象。7公斤的空压机不要调到8公斤用。榜首,平安得不到保证,第二,设备耐压也不行,寿数减短。所以需求多大压力,就选购相对应压力的空压机。

For example, when the practical pressure of a 0.7 MPa machine reaches 0.75 MPa, overload simply occurs. 7 kg air compressor should not be adjusted to 8 kg. No. 1, safety is not guaranteed. Secondly, the equipment can not withstand voltage and the life is shortened. So as much pressure as the demand is, choose the air compressor with the corresponding pressure.



三、接线松动:

3. Loose wiring:



查看输入螺杆空压机电源线能否有发热烧焦的痕迹,首要查看一下三相电压线,若有松动或短路情况,那么给予重接就好了。

To check whether the power supply line of the input screw air compressor has traces of heating and scorching, the first thing is to check the three-phase voltage line. If there is loosening or short circuit, then it is better to reconnect.



四、开山空压机接触器毛病:

4. Contactor faults of mountain air compressor:



接触器里边的触头老化,吸合不良,接触面就小,电流就大了,空压机过载是小事,电气系统焚毁才是我们不愿意看到的工作。

Contacts inside the contactor aging, poor suction, contact surface is small, the current is large, air compressor overload is a trivial matter, electrical system burning is the work we do not want to see.



五、开山空压机油气别离芯堵塞:

5. Blockage of oil and gas separated from core in mountain air compressor:



油分芯堵塞,内压高了,负载大了,电流就高了,所以会过载。误区:不要认为新换没多久的东西就不堵,现场环境脏,油气桶里边杂质多都简单使油分芯堵塞。新换的油分芯,环境也还能够,可是工作200小时又堵塞了,这是和油分芯质量有联系的。

The oil core is blocked, the internal pressure is high, the load is large, the current is high, so it will overload. Misconception: Do not think that new things will not be blocked soon, the site environment is dirty, and many impurities in the oil and gas barrel simply make the oil core separation blocked. The new oil core separation, the environment is also possible, but the work of 200 hours and blocked, which is related to the quality of oil core separation.
