Electric hydraulic operating table common fault solution

Electric operating table is very popular now, and it utilization rate in major hospitals is also very high, although operating table design life is very long, however, due to improper operation during normal use, or without regular maintenance, over time there will be some problems, such as the operating table will incline when use it, or automatic fall. Shandong Mingtai Medical Equipment Group Co., Ltd glad to tell you how to resolve it.

Firstly determine whether the solenoid valve failure, 2 ways: 1. use three-meter measuring resistance; 2. put metal on it to see whether there is suction. If the solenoid valve pull action is normal, the obstruction of the oil will also cause above problems.

Secondly determine whether the compression pump failure. First check whether there is voltage on compression pump, use three-meter measuring resistance, if the above are normal is generally commutation capacitor failure.

There is action in one side, no action in another side. Unilateral non-operational failure is generally caused by electromagnetic reversing valve. Electromagnetic reversing valve fault may be caused by bad control circuit, also may be reversing valve mechanical stuck. The specific inspection method is check whether there is voltage on reversing valve, if there is voltage then open reversing valve to clean it. Due to long-term use, if there is a little impurity on the movable shaft of the valve, the shaft will be burnt, which will cause the operation table move in only one direction.

Operating table will be automatically lowered down slowly. This situation is much more occurred in mechanical operating table, mainly because of pump failure. Small impurities may remain in the inlet valve after few years’ usage, resulting in minor leakage. The solution is to open the lift pump and clean it with gasoline, in particular, to check the inlet valve.

How to achieve intelligent control of electric hospital bed?

As medical device, electric hospital bed allows patients to rest and recuperate, the comfortable and convenience brought by scientific design have played an important role in the rehabilitation of patients. In order to facilitate the control system to control the electric hospital bed intelligently, knowing the hospital bed’s current working condition in time, it is necessary to install some sensors on hospital bed. The control system can understand in real time, control the movement state of the bed panel with date transmitted back through sensor to prevent interference from different institutions or unnecessary harm caused by overshoot of linear motor to bed and personnel. The sensor mainly adopts position sensor, including limit switch and proximity switch. The entire hospital bed contains a number of institutions that are structurally independent with each other, each of which corresponds to more than one degree of freedom, these institutions form a multi-open chain system under the unified control of the overall control system, completing different position adjustment through the movement of various bed panels. Therefore, the control system is a very important part for hospital bed, it is closely related with hospital bed’s structural design and motor selection. Before the control system is finalized, structural design, kinematics and dynamics of the hospital bed must be completed.

Hospital bed position is controlled by a single-chip control system, monitor the entire hospital bed system, including receiving keyboard and sensor position signals inputs, and motor control signals outputs.
