When removing the hex head bolt, if there is a sliding edge, you can take the following method: repair with a trowel and use a shackle to remove it: use a hacksaw to saw a slot on it, be careful not to be too deep, then use a vibrating screwdriver to remove it. A small sleeve (such as the original 19mm sleeve, now 18mm sleeve) is hammered with a hammer, so that it is firmly placed in the bolt or series black/white, Yamaha series is black, Kawasaki series Black/yellow; in the six-wire system, the Honda series is black, the Suzuki series is orange or orange/black, and the Yamaha and Kawasaki series are brown: when repairing, according to the corresponding function of each lead, the replacement operation will not If there is any difficulty, if the rectifier regulator of the permanent magnet type AC generator is damaged, the single-phase (called two-phase) full-wave rectifier regulator can be used emergencyly, and the three-phase AC power supply of the engine is removed. Thus the generator power wave is underutilized. Electromagnetic three-phase rectifier regulator Large-displacement motorcycle has an electromagnetic two-phase alternator that uses more power and efficiency and easier adjustment of output voltage. Some advanced electromagnetic alternators use an integrated electronic rectifier regulator and are housed in a generator. Most of the motorcycles are made of iron-type electromagnetic generators. Generally, six-wire three-phase rectifier regulators are used. The two leads are AC input lines; one output is DC positive; the root output is negatively grounded; one is connected to the engine. The excitation coil adjusts the current of the excitation coil circuit according to the magnitude of the output voltage, and the purpose of stabilizing the output voltage is as long as the function of each lead is recognized, and the corresponding connection can be replaced: the color of the two-phase AC input line of the electromagnetic rectifier regulator, The color of the positive and negative poles (ground) of the DC voltage output line and the color of the voltage regulator line are the same as those of the permanent magnet type three-phase rectifier regulator. The only thing to note is that the line of the excitation coil should not be mistaken. The Honda series is a white line, and the Yamaha series recognizes the function of each lead of the rectifier regulator for the green line. Correspondingly, the replacement can be replaced. Please check the wiring carefully. Do not connect the fault after the engine is started. If the outer casing is overheated, etc., take corresponding measures for different situations and solve it.
Commonly used methods are: surfacing method: first select the appropriate diameter of the electrode and the corresponding current, welding at the break. Solder, hold it down and solder it, be patient. Welded to a height of about 5 mm above the workpiece surface and shaped into a cylinder. A suitable nut is then welded over the welded cylinder. Wait a while, tap gently and spin out. When using this method, be careful not to weld the workpiece, so the welding technology must be too hard; in addition, this method is only suitable for breaking at the shallow surface of the workpiece. Drilling method: This method can only be used when the fracture is deep in the workpiece surface, that is, the hole is drilled in the center of the broken thread with the electric drill, and the diameter of the first bit should be selected smaller, and then the diameter of the drill is gradually replaced. Drill bit, slowly reaming. When approaching the broken thread, hit a quadrangular pyramid with a suitable diameter and rotate the quadrangular pyramid to remove the broken wire. When the wire is broken by this method, if the deviation is made during the punching, the internal thread of the component is damaged, which requires re-punching and tapping, which causes great trouble. Therefore, the assembly method a must be handled with caution. When installing, first tighten the bolts and nuts with the thread and then tighten the tools several times. In the process of tightening, in addition to the method of cross-assembly, attention should also be paid to the tightening torque of different threaded fasteners. Generally, the tightening torque of the threaded fastener can be judged by the feeling. The tightening torque of the important threaded fastener can be judged by the torque method, and the key thread fastener can be checked by the corner method. Therefore, professional maintenance personnel must have the tools to measure the tightening torque of the thread, and should also know the correct method of use and the torque parameters associated with it. b. Damaged threaded fasteners are not reusable. c. The scooter is connected by self-tapping screws in many places. When it is removed several times, it will slide the buckle. At this time, you can cut a piece of iron or aluminum alloy according to the original shape, and make a hole with a diameter slightly smaller than the diameter of the screw, and tighten the self-tapping screws. Just fine.
We can produce the A/SA106B/C steel pipes according to the ASME SA106 and ASTM A106 standards, YC has been granted a number of approval certificate by international institutions, such as Nuclear pipe certificate, 914mm Cylinder certificate, API monogram and certificate, ISO9001 by TUV NORD, ISO14001/OHSAS18001 by CQC, approvals from Shipping Classification Bureaus like DNV, RINA, ABS, Lloyd, GL, Bureau Veritas, and permit of exporting to Europe as PED 2014/68/EU and AD 2000 certificates for pressure pipes, CPD (Construction Products Directive), etc.
