(1) High reliability: The compressor has few parts and no wearing parts, so it runs reliably, has a long life, and the interval between overhauls can reach 40,000 to 80,000 hours;

　　(2) Convenient operation and maintenance: High degree of automation, operators do not need to go through long professional training, and can realize unattended operation;

　　(3) Good power balance: There is no unbalanced inertial force, it can run smoothly at high speed, and can realize no-base operation. It is especially suitable for use as a mobile compressor, with small volume, lightweight and less floor space;

　　(4) Strong adaptability: It has the characteristics of forced air delivery, the volume flow is almost not affected by the exhaust pressure, and it can maintain high efficiency in a wide speed range.

　　After a drill pipe is properly maintained, replace the screw oil, replace the three filters, and the diesel engine is also fully maintained, and the maintenance materials are all original parts, and there is no reason for the quality of the parts. When the oil return pipe of the oil return check valve was unloaded, it was found that the screw out resistance was great and it was difficult to screw. I had to disassemble the upper cover of the oil tank and found that the oil return pipe in the tank was bent into an arc and collided with the inner wall of the oil separation core. A lot of screw oil was accumulated on the bottom of the oil separation core. This phenomenon of course requires oil injection. Therefore, when replacing the built-in oil separator core, before opening the upper cover, the oil return pipe must be screwed out to ensure that the return pipe is not deformed or bent.

　　If a drill pipe is used correctly, it should be no problem for the diaphragm to be used for more than one year. Install a gas storage tank of 2 m3 or more in the gas transmission pipe, and adjust the screw machine when the three rock drills are working at full load at the same time. Inverse proportional control valve, when it reaches 0.65 MPa, the plunger of the intake valve servo cylinder extends about 1/2 stroke. In this situation, the intake air volume is controlled by the proportional valve capacity. As the air consumption increases and decreases, the intake air The valve will open and close with the expansion and contraction of the servo cylinder, but it will not open and close completely. The diaphragm of the servo cylinder can be smoothly opened and closed, the deformation is greatly reduced, and naturally, it will not wear out frequently. The user adjusted accordingly, and there was no more diaphragm rupture.
