1. the newly purchased drill, internal coated with viscosity larger rust grease, must be removed before use clear.When reloading, the moving parts of the table mina to grease.After installation, connect the drill to the compressed air pipeline, turn on the small wind operation, check whether the operation is normal.Inject lubricating oil into the automatic lubricator, commonly used lubricants are 20#, 30# and 40# oils.Containers for lubricating oil should be clean and covered to prevent rock powder and dirt from entering the lubricator.
2. Check the wind pressure and water pressure of the work site.The wind pressure is 0.4-0.6mpa, the high wind pressure will accelerate the damage of mechanical parts, too low will reduce drilling efficiency and corrosion of mechanical parts.The water pressure is generally 0.2-0.3mpa. If the water pressure is too high, the water will be poured into the machine to destroy the lubrication, reducing the efficiency of the drill and corroding the mechanical parts.If it is too low, the washing effect is not good.Whether the use of brazing metal meets the quality requirements, unqualified brazing metal is prohibited to use.
3. If the wind pipe is connected to the drill, it should be vented to blow out the dirt in the pass.Receive water pipe money, want waterproof to flush the filth at the joint, air pipe and water pipe must tighten, fall off in case hurt.Insert the brazing tail into the drill head and turn the drill clockwise. If the drill can not be turned, it indicates that there is a jam in the machine, which should be dealt with in time.
4. Tighten the connection bolts, open the air to check the operation of the propeller, and start working only when the propeller is running normally.Guide rail drill should be set up a pillar, and check the operation of the propeller, air leg drill and upward drill must check the flexibility of its air leg.
5, the hydraulic drill should be required to have a good sealing of the hydraulic system, to prevent the hydraulic oil pollution, to ensure that the hydraulic oil has a constant pressure.
6. When the drill is used, the compressed air at the inlet of the drill is required to be dry, and the wind pressure should be kept at 500kPa, with a minimum of 400kPa;Requirements to use clean soft water, in the use of acid or alkaline water, the drill after the completion of work should be immediately injected some lubricating oil, water off empty operation for a little time.
7. Cleaning and reloading should be carried out when the new machine is started. After reloading, an empty car should be opened to check whether the operation is normal.But the empty time can not exceed 2~3min..Too long time, the air cushion area of the cylinder temperature is too high, easy to produce cylinder phenomenon.Do a good job of pipeline cleaning and routine disassembly maintenance work, is the machine is often in good working condition, and should often pay attention to add lubricating oil, no oil operations are prohibited.
8, the operation should pay attention to the first open the wind before the water, first turn off the water before the wind, and pay attention to the water pressure should be lower than the wind pressure, prevent the water backflow drill cylinder, damage the normal lubrication of the machine, affect the normal operation of the machine.When the drill card fiber rotation is slow, should be immediately through the pressure regulating valve to reduce the air leg of the axial force.If the fiber rod has not turned, after reducing the axial thrust of the air leg invalid, should immediately stop drilling, eliminate the failure to drill after the failure.
9, often observe the discharge of the machine, the gas leg drill is not allowed to remove the water needle operation, or dry hole.
10, when the telescopic drill upward operation, pay attention to the magmatic down along the drill is not close to the fiber sleeve, the spacing should be at least 20mm, otherwise, that is, the insufficient purging force, at this time according to the procedure to check whether the blowing hole on the fiber sleeve is unobstructed.When the telescopic drill upward operation, in addition to comply with the general drill work safety technology, but also should pay special attention to the drill suddenly broken, to prevent injury accidents, and prohibit a long time full speed idling, pull the fiber should open a car.
11. After the work is finished, close the water valve to let the drill run empty for a short time with a small wind to remove water and prevent corrosion.On the guide rail type drill, when a fiber is finished, should stop the wind, and then hit the reverse removal of the fiber tail.When reversing the unloading, should open a small wind.If you change from a forward turning to a reverse, inertia will produce a great impact, which will reduce the service life of the screw rod of the rotary claw.When the drill is stopped for a long time, it should be removed and cleaned in time, and coated with anti-rust oil, and stored in a dry place.
