Solving methods of common faults in electric hydraulic surgical table
The Electric Hydraulic Surgical Instrument Table is now very popular, in each big hospital rate is very high, while the electric operation bed design life is very long, but as usual during use or improper operation, no serious maintenance will appear, days and months multiplying some problems, for example in the process of using electric operation bed tilt or automatic fault location the whereabouts of Shandong Mingtai medical group specializing in the production of electric operation bed manufacturers tell you how to deal with the identity of the first to determine what solenoid valve has no fault judging method includes two kinds: one is to use three meter measuring resistance, another metal put up to see if there is no suction. Of course, if the solenoid valve sucking action is normal. And the oil road blocking will also take place above the above problems.
Then judge whether there is a failure in the compression pump. First check the voltage on the compression pump, use three to compress the resistance of the pump, if the foregoing is normally the commutation capacitor failure. The electric operating table has one direction in one direction and there is no action in the other direction. The single side no action fault is usually caused by the electromagnetic reversing valve. The fault of the electromagnetic reversing valve may be caused by the bad control circuit or the mechanical card death of the reversing valve. The specific inspection method is the first quantity of the commutation valve has no voltage. If there is a operating bed voltage, the reversing valve is dismantled and cleaned.
Because of the long-term use, for ask valve shaft tens of thousands of an a little bit small impurities will cause the shaft galling stuck, causing the operating table only one direction of movement. It is found that the operating table will be automatically reduced, but the speed is very slow. This kind of situation occurs in the mechanical operating table more, mainly is the lift pump failure. A few years after the use of the operating table, small impurities may occur at the entrance of the oil intake valve, causing tiny leaks. The solution is to remove the lift pump with gasoline cleaning, especially to check the oil intake valve.
