Parameter meaning of pneumatic wrench

Many types of pneumatic wrenches, such as impact wrenches, torque wrenches, constant-torque wrenches, and air cannons, are pneumatic wrenches. They are widely used in many industries, such as automobile repair, heavy equipment maintenance, product assembly, major construction projects, and high torque output needs anywhere else. At the same time, pneumatic wrench is also known as the combination of pneumatic ratchet wrench and electric tool. It is mainly a tool that provides high torque output with small consumption of Z.
There are many parameters of pneumatic wrench, and each parameter represents a different performance. The following is a summary of the information of some parameters and functions of pneumatic wrench, which you can refer to:
1. CH1: channel 1, normally used, the indicator light is on and effective; (Number 7)
2. CH2: channel 2, which is not normally used and does not need to be set; (Number 8)
3. Strike stop: refers to the time between "action state" and "stop state" of the pneumatic wrench; (Reference value: 2) (number 9)
4. Rebound force: refers to the pressure fluctuation in the trachea during the action, and the large rebound force will be generated when the blow force is large; (Reference value: 4) (number 4)
5. Number of blows: refers to the number of effective blows. When the number of effective blows reaches the set value, the tightening is considered to be completed. After a certain time (release time), the solenoid valve acts to disconnect the air source and tighten one piece (reference value: 5-20, the greater the value, the greater the torque) (number 5)
6. Release time: refers to the working time of the solenoid valve, after which the wrench can be operated again; That is, the time between the automatic disconnection of one air source and the unscrewing of the other; (Reference value: 15) (number 6)
7. Number of strikes: refers to the number of bolts to be tightened for a workpiece (reference value: equal to the number of bolts) (number 1)
8. Operation time: refers to the operation time when all bolts on a workpiece have been tightened. The work needs to be completed within this time, otherwise it will be counted again; (Reference value: 99) (number 2)
9. Overwrite strike: the effective strike is covered by the count, which usually does not need to be set; (Reference value: 3) (number 3)

In addition, there are several precautions for pneumatic wrench:
1. When striking workpieces of different sizes, it is necessary to set the "number of blows". The number of blows is in direct proportion to the tightening torque of bolts. (Suggestion: record the number of blows corresponding to the tightening torque of bolts of each model, and make a table and paste it on the conspicuous position of the equipment)
2. When striking, please tighten the bolt by hand for 2 to 4 teeth in advance
3. Press and hold the pneumatic wrench switch all the time when striking, without interruption, until it stops automatically
4. When the switch is held down all the time, the resilience index will jump all the time. Each time the set value is passed, the number of blows will increase by 1. When the number of blows increases to the set value, a bolt will be tightened
5. After tightening, the pneumatic wrench will be out of gas for a period of time (release time), and then the second bolt can be tightened and repeated in sequence.
6. During the striking process, the keyboard will display the number of striking pieces. When a bolt is successfully struck, the number of striking pieces will automatically decrease by 1, (when the pneumatic wrench is out of air for 10 seconds, it means successful striking)
7. Alarm reason:
A. The strike is not completed within the "working time" after the start of the strike
B. Failure to complete a bolt blow count within the specified time can be understood as insufficient torque
C. To release the alarm, just press the red release button on the lower panel
