ZY28 air leg type drilling machine principle of work
When the drill before starting, high pressure gas through the handle body sequentially through the control valve into the gas chamber, a dish type valve has alternately cavity gas into the cylinder, which pushes the piston high-speed reciprocating action, residual gas work by silencing hood exhaust.
A piston, punching, return movement principle
The gas through the valve hole, the air chamber into the handle, the ratchet wheel hole channel, into the valve cabinet air chamber, when the valve and the valve is closed after the cabinet, gas chamber through a guide hole of the valve sleeve into the cylinder, push the piston to move forward the formation of shock travel. When the front end of the piston surface over the exhaust port, the front cavity gas cylinder by the piston compression on the formation of air cushion, instant pressure increased, the gas is compressed along the range front cavity hole back to the distribution valve after the gas chamber, when the piston to move on, along with the increased pressure, forcing the valve movement trend, when the gas cavity. After the end of the piston body across the exhaust is exhausted from the exhaust port, air pressure drop back cavity, the pressure and the chamber after push valve moves forward, instant valve and valve cover closed, cutting off the gas chamber cylinder, piston rod end moments, stroke, began to return. When the valve and the valve cover is closed, cut off the gas to the cylinder chamber gas, gas along the gap between the outer circle and the valve chest of the valve into the chamber after, into the cylinder along the front cavity lead hole, push the piston back, began to return after the end of the piston movement, when over exhaust, gas cylinder body cavity formed by a compression piston
Air cushion, the pressure increased, forcing the valve after the shift, when the front end of the piston surface over the exhaust port, air pressure drop before the exhaust cylinder cavity, and the cylinder pressure air chamber and push the valve after the shift, the valve and the valve closed end cabinet, return, began to stroke.
Principle two, rotary drill rod
Drill rod of Rotary is the return process of piston. The big end of the piston is arranged in the screw nut, is integrated into the piston. Because the end part of the screw rod is provided with a
A non-return mechanism, by the pawl of the ratchet wheel and ratchet engagement, tooth spiral rod tooth profile and helix master match, only the spiral rod for clockwise rotation, so it can not be reversed, in the piston into the drill rod, the helical, spiral rod only make clockwise rotation, in return in the process, a non-return mechanism makes the spiral rod can not be reversed, and the piston then rotates counterclockwise, the rotating sleeve to the drill rod, a drill rod operation completed.
The use and maintenance of ZY28 air leg drill
1, the new machine must be parts of internal disassembly and cleaning before use, remove the machines in the factory of the coated anti rust oil, cleaning after the installed parts surface to recoat lubricating oil, should be used in low pressure (0.3Mpa) or semi on state run 10
Minutes, can work normally.
The pipe pressure air supply pipe 2, should be in the range of 0.5-0.6Mpa, if the pressure is too high easily damaged parts, if the pressure is too low,
The drilling efficiency decreased significantly, resulting in drilling machine can not be used normally.
3, before the gas supply pipe and drilling machine is switched on, the first blow the trachea of the dirt, lest dirt blown into the body so that the valve failure and damage parts. Before the gas water on the boot, check the thread connection part is tightened, can be formally boot.
4, the machine after the first test atomization is oil mist is suitable, adjust good, work in process, every 1 hours to the oil mist device to fill a oil, not without lubrication.
5, the machine should be in the running start, in the gas leg pushing force increases gradually at the same time, can open full drill. May not be full operation in air leg thrust is maximum, which may lead to the death card, not long time off at full speed, to avoid wear parts.
The 6, cutting finished hole drill drawing, should be based on medium speed, if the stop not punctured, the tube removed, blowing machine in residual water stains, to prevent corrosion of internal parts.
7, the rock drill for water wet center drill, no dry holes, but are not allowed to remove water needle work, avoid dust along the drill hole pours into the body, resulting in various parts of failure, is not functioning properly, will cause serious damage to parts.
After the boot, check the thread connection part is tightened, can be formally boot.
