Electric operating table fault analysis

作者:admin  发布时间:2017-05-02
1. Don’t have forward tilt
If only don’t have the forward tilt function, other actions have, it shows that the pump is working properly, but the corresponding membrane switch failure or the corresponding solenoid valve failure. There are two ways to determine the solenoid valve is good or bad. One is measured with a three-meter resistance, and the other with a metal to see if there is no suction. Of course, if the solenoid valve pull action is normal, oil blocking also will occur the above problems.
If not only don’t have forward tilt function, others also don’t have, compression pump failure. First check whether there is voltage on the compression pump, amount compression pump resistance with three tables to see whether it is normal? If the above are generally normal, commutation capacitor failure.
2. One direction have action, another direction no action
Unilateral no action failure is generally caused by electromagnetic valve. Electromagnetic reversing valve failure may be caused by poor control circuit, mechanical valve may also be stuck. The specific inspection method is: first amount the valve to see whether there is voltage. If there is voltage open the valve then clean it. As a result of long-term use, if there is a little small impurities on the valve activity axis will cause stuck hair, causing the operating table only one direction action.
3. Automatically drop down when using, but the speed is very slow.
This mainly happens in the mechanical operating table, mainly lift pump failure. After long time using, very small impurities remain in the inlet valve, resulting in a small internal leakage. The solution is to remove the lift pump with gasoline cleaning, in particular, to check the oil into valve. After washing to re-add clean oil.
4. Automatically drop down when using, faster, and vibration sound.
This failure is the problem of the inner wall of the tub. Long-time action up and down, if the bowl has a little bit of impurities. Sometimes it will pull out scratches on tubing wall, after long time, scratches more and more deep to produce the above failure. The solution is to replace the tub.
5. Back board automatically drop down when using, but the speed is very slow.
This failure is mainly due to leakage caused by the solenoid valve, generally occurs in the electric operating table, after long time using, impurities will gather in the solenoid valve port. The solution is to remove the solenoid valve with gasoline cleaning. Need to pay attention to that due to the large back pressure, generally electric operating table has two solenoid valve in series, two should be clean together.
