Problems and solutions about pressure calibrator
2011-10-26 14:44:33

压力 校验仪 压力不稳或 不能正常造压 First, the pressure of the pressure calibrator is unstable or cannot be properly pressured
  原因: Reason:

   油箱 内的 油量不足。 1. There is not enough oil in the fuel tank .
   、在 运输 管路接头处损坏有泄漏。 2. The pipeline joint is damaged and leaked during transportation .
   快速接头 o " 型圈密封损坏。 3 , quick connector " o " ring seal is damaged.
   系统内 空气较多或 者没有清 排干净。 4. There is more air in the system or it is not cleaned.
  处理方法: Handling method:
    松开 油箱的 油箱帽或 给油箱加 油。 1. Loosen the fuel tank cap of the fuel tank or fill the tank with oil .

松开油箱 接头。 2. Loosen the connector of the fuel tank .
    更换 o " 型圈。 3. Replace " o " ring.
    反复抽动充油泵使 系统内 部的 空气随油箱排出。 4. Repeatedly pump the oil-filling pump to make the air inside the system exhaust with the fuel tank.
负压达不到标准 Second, the negative pressure of the pressure calibrator does not reach the standard
  原因: Reason:
   1. The reversing valve cannot be reversed, resulting in air leakage.
   负压单向阀运动之后没有复位,造成空压现象。 2. The positive pressure check valve or negative pressure check valve does not reset after moving, causing air pressure.
  处理方法: Handling method:
   ,同时 换向阀杆不能半空悬浮。 1. The reversing valve must be reversed in place , and the reversing valve stem cannot be suspended in the air.
   不是 没有达到要求。 2. Check whether the positive pressure and negative pressure check valve seat holes do not meet the requirements.
   3. The spring tilts badly, and the check spool cannot slide freely.
