罗茨真空泵温度过高的原因

  罗茨真空泵工作时,温度过高容易导致转子卡死,严重时会损坏设备。在这种情况下,我们必须考虑其他情况。造成这种现象的原因有很多。下面介绍一下罗茨真空泵温度过高的原因

  一、气流不足。

  确保罗茨真空泵的冷却系统不会被灰尘或污垢堵塞,清洁风扇罩、风扇、通风格栅和冷却销,只有确认足够的通风后才能安装泵。

  二、环境温度过高,进气温度过高。

  符合真空泵工作环境温度范围要求,符合进气温度范围要求。

  三、部分排气过滤器堵塞。

  更换排气过滤器。

  4.油过滤器堵塞(油只能通过旁边的通道流动,不再过滤)

  更换机油滤清器。

  5.油箱里的油不够。

  需要加油。

  六、油过热变质。

  清洗罗茨真空泵,更换机油过滤器,更换排气过滤器,注入新油。如果油寿命过长,更换热绝缘好的油或冷却系统。

  7.电源频率或电压超出正常范围。

  提供更稳定的电源。

  8.过滤器或过滤网堵塞。进气、出风口或压力管道堵塞。

  清除堵塞物。

  9.进气、排气或压力管直径过小或管长过长。

  更换符合要求的管道。

  在罗茨真空泵的运行过程中,应注意罗茨真空泵各部分的温度升高,以确保循环冷却水的进出。当真空泵在工作中漏油时,应及时停止工作,并在负压后进行检查和维护。在漏油的情况下,真空泵不能继续运行,做好上述工作,可减少真空泵过热的次数。

检查罗茨真空泵时的注意事项

  要知道,如果罗茨真空泵定期维护,可以降低设备故障率,使其使用效果不受影响。但是为了保证设备的维护效果,维护时必须注意以下几点:

  1.罗茨真空泵的泵座上不得放置维护工具和任何物体,以保持电机接地线不变。清洁时,注意不要向电机喷水。

  二、维修前应处理相关的安全维护程序。

  3.切断电源,释放剩余液体,切断入口。出口阀或堵塞的盲板与系统隔离。挂禁动卡。

  4.拆卸、清洁、更换零件和维护工具应整齐地放置,以实现文明维护。

  5.及时更换罗茨真空泵上的无效密封和其他润滑部件。

  6.油管接头包装密封带、密封线等。;改变不合理的结构和装置。

  因此,在维护罗茨真空泵时,只有更好地维护自己的维护方法是否正确,自己的安全保护措施是否到位,才能更好地保证设备的维护效果。同时,检查设备附件。零件时,一定要注意自己的维护力,不要用力过猛,以免损坏零件。


  Causes of high temperature of Roots vacuum pump

  When roots vacuum pump is working, the rotor may be stuck due to high temperature, and the equipment may be damaged in serious cases. In this case, we must consider other situations. There are many reasons for this phenomenon. Here is the reason why the temperature of Roots vacuum pump is too high.

  1、 Insufficient air flow.

  Ensure that the cooling system of Roots vacuum pump is not blocked by dust or dirt. Clean the fan cover, fan, ventilation grille and cooling pin. Install the pump only after confirming sufficient ventilation.

  2、 The ambient temperature is too high, and the intake air temperature is too high.

  It meets the requirements of the working environment temperature range of the vacuum pump and the inlet air temperature range.

  3、 Some exhaust filters are blocked.

  Replace the exhaust filter.

  4. the oil filter is blocked (the oil can only flow through the nearby channel and is no longer filtered)

  Replace the oil filter.

  5. there is not enough oil in the oil tank.

  Need to refuel.

  6、 The oil is overheated and deteriorated.

  Clean roots vacuum pump, replace engine oil filter, replace exhaust filter and inject new oil. If the oil life is too long, replace the thermally insulated oil or the cooling system.

  7. the power frequency or voltage exceeds the normal range.

  Provide more stable power supply.

  8. filter or filter screen is blocked. The air inlet, air outlet or pressure pipe is blocked.

  Remove the blockage.

  9. the diameter of air inlet, exhaust or pressure pipe is too small or the pipe length is too long.

  Replace the pipes that meet the requirements.

  During the operation of Roots vacuum pump, pay attention to the temperature rise of all parts of Roots vacuum pump to ensure the inlet and outlet of circulating cooling water. When the vacuum pump leaks oil during operation, it shall stop working in time and conduct inspection and maintenance after negative pressure. In case of oil leakage, the vacuum pump cannot continue to operate. Doing the above work can reduce the times of overheating of the vacuum pump.

  Precautions when checking roots vacuum pump

  You should know that if roots vacuum pump is regularly maintained, the equipment failure rate can be reduced, so that its use effect will not be affected. However, in order to ensure the maintenance effect of the equipment, the following points must be paid attention to during maintenance:

  1. maintenance tools and any objects shall not be placed on the pump base of Roots vacuum pump to keep the motor grounding wire unchanged. When cleaning, be careful not to spray water on the motor.

  2、 Relevant safety maintenance procedures shall be handled before maintenance.

  3. cut off the power supply, release the remaining liquid and cut off the inlet. The outlet valve or blocked blind plate is isolated from the system. Hang the immobiliser card.

  4. disassembly, cleaning, replacement parts and maintenance tools shall be placed neatly to achieve civilized maintenance.

  5. replace the invalid seals and other lubricating parts on Roots vacuum pump in time.

  6. oil pipe joint packing sealing belt, sealing line, etc.; Change unreasonable structures and devices.

  Therefore, when maintaining roots vacuum pump, only by better maintaining whether the maintenance method is correct and whether the safety protection measures are in place can the maintenance effect of the equipment be better guaranteed. Meanwhile, check the equipment accessories. When using parts, you must pay attention to your own maintenance force. Do not use too much force to avoid damaging parts.
