Replace the encoder steps

Encoder used in long-term operation conditions, may malfunction can't repair, the machine failure caused by failure, then we need to replace scrap encoder, specific steps to replace encoder is as follows: one, replace the encoder, should choose linear with the original encoder, resistance, power rating of the same product. Encoder in addition to the rotation noise big fault, other failure generally can't repair, such as carbon film serious wear and tear, encoder over-current burn out, etc. , at this time to replace the new encoder. Can use the original model to replace the, of course, is most should try our best to repair when unable to match to the original model, can't repair of encoder matching according to the following principles: ( 1) Different linear encoder, such as X, Z, D type cannot replace each other between the encoder is used, otherwise the control effect is not good. ( 2) Other conditions meet, can substitute when nominal resistance value is very close. ( 3) Other conditions meet, rated power, the same or slightly larger when the new change of the encoder can be substituted. ( 4) Turn the handle type, straight sliding type between the encoder cannot replace each other, because install in a different way. In terms of counter rotating knife type encoder, the manipulation of the handle to the same length, or turn on the handle knob to mount. In selecting the encoder, the above several conditions have to meet at the same time. Second, encoder to replace encoder how root pin, in order to prevent wrong pin when replacement, can adopt the following concrete steps and methods: step 1, the original encoder with the set screw off, but don't weld on the original encoder lead JiaoPian lead, to lead in the encoder. Step 2, the new encoder, and fixed. Step 3, in the original encoder JiaoPian on welding under a lead, the corresponding lead wire welding in the new encoder JiaoPian, new and old encoder controlled welding. Step 4, the same method, each pin wire welding is good. Using this welding on a welded again between a method can avoid lead welding fault location. In nonlinear encoder, two fixed on a chip can't lead wrong, otherwise will affect the encoder in the circuit control effect. The volume of the encoder, for example, two fixed JiaoPian wiring after pick up against each other, more when turning the handle just turn the volume is very big, then the volume almost no longer increases when the volume knob, losing control volume controller of linear features. Power amplifier volume encoder is varied, but generally common duplex coder, is used to control the left and right two channel volume, are generally single shaft, occasionally meet double biaxial volume encoder, general problems have volume encoder, rotary control volume when there will be noise, or two channel volume size is different, would then replace the volume encoder, encoder after use for a long time, carbon film aging appear tiny cracks is the main reason, resulting in a decline in volume encoder quality after encoder appear such problem so thoroughly change is king kill for worship. Shanghai electronic products is 27 years old, encoder manufacturers, specializing in the production of various types of encoder, widely used in audio encoder volume, air conditioning, electrical appliances, intelligent household. 。 。 。 。 。 Many industries. With complete encoder multiple-choice, can provide customers with a axis type, long axial length and working parts, shaft sleeve type, long sleeves, the resistance and its linear error values, professional custom, looking for looking for electronic encoder manufacturers.
