The product from Shandong Huajian company specializes produced, ZQS-65 / 2.5S Pneumatic handheld rig explosion safe, torque, light weight, small size, reasonable structure, easy maintenance. Mainly used in coal mine stirred and tray resin bolt nut installation. ZQS-65 / 2.5S Pneumatic handheld rig use significantly improved installation efficiency and supporting quality resin bolt, reduce labor intensity and improve working conditions. 1. The working principle of compressed air through the filter, lubricator, filter, into the bolt rig. Turn on the motor control valve, compressed air drive gear motors, the gear, drive shaft clockwise, adjust the knob to control the motor operating status . Turned wet drilling valve, flush water through the filter that is, water pipes, spindle bore into the drill pipe, flush drilling, regulating valve opening amount, you can adjust the size of the water. ? 2.? ZQS-65 / 2.5S Pneumatic handheld rig conditions? 2.1 Compressed air should be kept 0.4 ~ 0.63MPa, measured from the rig around the air inlet 5 m. To clean and dry compressed air, such as those containing excess moisture will damage the inner parts of the surface of the film an air motor, so that lubrication to deteriorate, and the exhaust inside the ice hole, blocking the exhaust path, so that the rig can not operate normally. ? In order to exclude the excess moisture in the compressed air, compressed air piping to configure efficient gas water separation device, and before each drilling, water emissions. Compressed air piping also configure the oiler to ensure lubrication. ? 2.2 wet wash drilling water quality should be clean, otherwise easily clog waterways, water pressure should be maintained 0.6 ~ 1.2MPa. Water down the impact of timely discharge of cuttings from the borehole, and thus can not achieve the desired drilling speed can not be fully effective rig. Every drilling was completed, the valve should be closed, let ZQS-65 / 2.5S operating a hand-held pneumatic drilling rig will be beneficial to the water rust. ? 2.3 ZQS-65 / 2.5S pneumatic hand-held drill lubrication ambient temperature -15 ℃ ~ 10 ℃, can be used on the 20th machine oil. Ambient temperature at 10 ℃ ~ 35 ℃, can be used on the 30th mechanical oil. The air motor bearings, gears lubricated gearbox rig pay and rolling bearings, 3. Use the 2nd synthetic lithium grease (EP-2). ? Lubrication job? When the rig is prohibited without oil operations, the machine should be equipped with FY200A hanging type Molded oiler. When in use, should be adjusted out of fuel, lubricating oil consumption of 2 to 3 ml per minute is appropriate. When servicing the gas motor and transmission box, deal with Rolling Note to ZL-2 grease. ? Drill drill drill can be rowed or twist drill rod; using hexagonal drill pipe, its tail even hexagonal edge size 19mm. When using twist drill rod, twist drill rod should be accompanied by the appropriate connector. Prohibiting the use of a curved drill pipe. ? The manipulation? ZQS-65 / 2.5S pneumatic hand-held drill only one person can manipulate, control valve flow left hand, right hand control motor rotation speed. ? 5.? ZQS-65 / 2.5S check Pneumatic handheld rig before? 5.1 should meet "7. Use the condition" of the requirements. ? 5.2 connection put the gas, before the water fittings, rig valve knob must be in the closed position. ? 5.3 every time you install an intake, should be preceded by opening the inlet valve of the piping, the inner piping impurities or water blowing and fittings clean. ? 5.4 Before drilling, the first no-load operation, check the motor rotation, valve control, all is normal, in order to put into operation. ?
