Centrifugal fault repair two cases (2)

Failure GL21M centrifuge door cover can not open GL21M high-speed refrigerated centrifuge produced by Hunan Kaida Science Instrument Co., Ltd., the maximum speed of the centrifuge is 21,000 rev / min. Due to the extremely high speed of the centrifuge during operation, for safety reasons, the centrifuge is equipped with a protective device, that is, the cover can be closed to work, and the cover can be opened after shutdown. However, after one use, the lid cannot be opened and the sample cannot be removed!

After consulting the information, the protective device of the aircraft is a manual mechanical lock. Its structure is similar to ordinary door locks. Pulling the handle in the lower right corner of the cover can pull the latch out of the lock hole, and the air spring stays. The cover can be opened by the lever. Since the handle and the latch are connected by an "L" type iron piece, that is, one end of the "L" type iron piece is connected to the handle, and the other end is connected to the lock bolt. Both ends of the connection piece are screwed The reason that the door cover cannot be opened is that the fixed screw slips or loosens, eventually causing the connection to disengage, and the latch cannot be pulled out of the lock hole, so that the door cover cannot be opened.

When this failure is encountered, the lower half of the front panel of the centrifuge can be disassembled (the front panel consists of two upper and lower pieces) with the power of the centrifuge cut off, and then the approximate position of the door lock can be probed into the left hand and hand-held. Pulling the “L” iron piece backwards, if it cannot open the door cover, it means that the connection of the “L” iron piece to the latch end has slipped. At this time, a screw with a diameter of 6 mm and a length of about 5 cm can be used, clockwise. Slowly twist it into the rear end of the person's latch and after a few turns, pull back the screw to pull the latch out of the lock hole and open the door cover. After opening, remove the door lock assembly, replace the screw of the sliding teeth, reconnect the two ends of the “L” iron piece, and apply a little grease on the latch and lock hole to reset the door lock assembly.
