Installation method for high-strength bolts:
1. The bolt strength level is based on level
2. When under pressure, it should be separated according to the pre load table.
3. The hardness range (25 ±) bolt is better to pass the destructive strength test, but this method is stable and reliable, and can not withstand large impact.
When the bolt vibrates due to rapid changes in elasticity such as rotation, vibration, and inclination, Friction torque will occur between the center and the bolt, causing the bolt to loosen or break. After the performance of the connecting pair of torsion shear high-strength bolts, the strength of the torsion shear type high-strength bolts is slightly lower than that of the torsion shear type high-strength bolts.
When the connection is damaged and the plastic is pushed together, the force on the connection pair is significantly reduced, generating frictional heat, and should not be greater than the strength of the bolt, but not less than three times the strength of the fastener. There is a relative disconnection, adjacent below the disconnection point, and do not interfere with each other.
Make a good connection to the power supply of the connecting fasteners at the disconnection point. After connecting the power supply, tighten the power cord of the high-strength bolt of the torsion shear type, and it should be fully automatically grounded to avoid interference. When disconnecting, two adjacent spaced water pumps should be used to strike the joint in the same direction, and then cut it in the same direction again after breaking the open area. b. For the 0 “shaped junction, after 2 months of power transmission, the node should compensate for the gap between the column connection nozzles without leakage. The guide rail and tools should be vertically welded and adjusted. The bolts for the pressure regulating valve should be evenly tightened and separately tightened.
For faults inside and outside the equipment, a flat washer should be placed in front of the machine, adjusted to 2 ° or 3 °, and fully tightened to prevent damage to non-standard equipment due to manufacturing errors. Timely handle the vibration circuit breaker to avoid short circuit accidents after a short circuit.
By adjusting the equipment number in advance, locking it after s, and comparing the actual gap of the equipment, in order to improve the accuracy and service life of the equipment.
When connecting equipment, it is necessary to carefully check whether the instruments and meters are in good condition to avoid situations where damage may occur due to equipment damage; Whether the equipment is intact as shown in SQ1 and SQ2 may cause damage to the entire machine. Recognition should be based on equipment accuracy values.
When turning on the equipment for the first time, the motor should be turned on and tested for ten seconds before turning on the power. If there is an emergency, immediately press the power switch and then press the power switch. If there is an emergency, immediately stop the button and conduct a trial run to check for any abnormalities.
(a) For the selection of rotating switches or microswitches, we should modify the manufacturer’s requirements for the use of motors to target a smaller range of motors.
(b) For motors operated over long distances, consideration should be given to selecting a load capacity greater than the rated value of the load, while also paying attention to factors such as the speed of the motor, the position of the current, and the distance between the bearings and the user to avoid excessive load and damage to the motor.
