Coefficient multiplier and pulse distributor maintenance skills


Measurement technology as shown in the passage of 1999. № 747 PP available instrument to measure the frequency of a 1la (set period file). Output period of a level measurement, the other two are set to zero the number of dial in order to avoid mutual involvement. Otherwise, the top level must be added 12 feet to the periodic signal. Once 12l4 foot out there, it should check the level circuitry, respectively, is normal, 4 to 7 feet of the potential and the dial number is set to one correspondence. 2 and 8 feet is in the 0 level. Without exception,[link widoczny dla zalogowanych], will have to consider replacing the components 5G671. Of course, in the small-signal removal except under the conditions of work. The relationship between input and output equation can also be expressed: T2 = T × l0 / M or Tx10, which is an index of one hundred, ten is 2 bits is 3, M the number of representatives of the dial is set. It should be noted, due to the differences in performance caused by component measurement results within a certain range of error change is normal. Hoard 2, Figure 3 Measurement Technology 1999. Ng. 7 and the relationship between input signal proportional to the pulse signal is used a multimeter to measure the transistor collector-emitter voltage, 5G671 output signal, amplified by the BG-driven stepper or l1-15, or 2O a 15 voltage, the saturation turns on the machine, must also be formed by the two groups of four bistable 3DK 0V, the deadline for the 22V. Touch 1, the circuit turn 1, the state circuit (model HM - 7510) to obtain the necessary current and voltage changes in the corresponding time. 4 times per strike, to achieve recovery pulse distribution circuit (Figure 2). Added to the base by a negative pulse, the status quo. Can also measure the voltage on the stepper motor windings, such as u turn on a tube saturation, flip the bistable circuit, resulting in two 5 or 20-5,[link widoczny dla zalogowanych], is similar with the above, the bistable circuit voltages were set rotation flip, so that the stepper motor at each change of a 22V and 2V, the circuit once every turn, the stepper motor to turn the direction of rotation. Accordingly, like the work of bistable circuit judge step. Situation, you can no pulse signal input conditions, holding a gold machine to facilitate debugging and maintenance, are listed in the multiplication factor is a forceps, with its cutting-edge parts of touch input devices and the bistable circuit some common pulse distributor fault diagnosis procedure (see Figure-side foot to flip the circuit external disturbance force. this time 'if. f fat 1 snail meal degrees steelyard with a pan-sided spring tune check 0I Gan Yuzhong, copper, (Guangxi La La J_I County J_I County Standard 541,200) First, the commissioning of new spring assembly or repair the degree steelyard with a pan needs to be debugged. debug is to enable the scale of the stability, sensitivity, accuracy and repeatability of four performance test procedures required to achieve an important work. 1. Commissioning Preparing to be ready before commissioning the necessary tools and four other weight. Check the screws on parts are tight, institutions are turning the rotating parts of a flexible or too loose, swinging and rotating the pointer is the normal 2. . ATZ debugger spring double face debug degree steelyard with a pan should be on one side (A side) of transmission of debugging,[link widoczny dla zalogowanych], then the opposite side (B side) transmission debugging. specific debugging steps are as follows: (1) The scale should be placed In the level surface. (2) Remove the A side glass mask, slightly tighten the screw loosening dial to adjust the dial and the gear shaft 5 - coincidence, and dial zero in the scale shell axis, then tighten the dial close fixation screws. (3) Remove the mask B ring, glass mask,[link widoczny dla zalogowanych], dial, degree-hours cover. Loosen bottom screw, the relocation limit column, so that from the meshing gears and the rack, turn the A pointer to make it close to zero surface Office (both zero range), and then adjusting the stopper, so that re-meshing gears and rack. (4) rotating zero nut, so the pointer aligned to zero. test points A surface, such as tolerance, adjustable the number of coils, until the test procedures to meet the requirements in the ending of the tolerance. (5) assembly of the degree-hours a Part B shell dial. (6) B surface of the dial slightly tighten loose screws, adjust the dial center and gear center coincide, and dial zero in the scale body axis, tighten the screws tighten the dial, fitted with a pointer. (7) If the pointer is not aligned zero, within about ± 1d, can tighten the screws slightly loose dial, so that degree of coil axis rotation, move the pointer and dial zero alignment, then tighten the screws fastening the dial. If the pointer is obvious deviation from zero, then the axis coincides with the scale body. to remove the pointer to a pointer with the sleeve each other Turn a declination. just to make the pointer aligned with the zero point. ( drops by 502 glue between the pointer and the sleeve is fixed at one to make, the load gear shaft, then tighten the nut pointer. Finally fitted with A, B side glass mask. Second, the maintenance of the scale used often due to collision,[link widoczny dla zalogowanych], rain and rust, acid corrosion and wear parts for various reasons such a long time, so that damage or wrong, to be repaired. To repair person sentenced as quickly as possible
