Economical concentric tube micro-lubrication device application


Concentric tube Tuel oil and gas lubrication system is suitable for machine tool electric spindle and various high-speed bearings, center frame, guide rail, screw and other oil and gas lubrication. It is especially suitable for external cooling metal cutting, suitable for gear machining, milling, turning and drilling. , the machining center and other external processing of machine tools and the transformation of old machine tools to achieve energy saving and environmental protection.

Combined with the nozzle to achieve lubrication and cooling, to prevent wear and tear; oil and gas distribution, mixing at the end of the lubrication point makes lubrication more reliable. The feed frequency of the pneumatic micropump is controlled by the autonomous controller, and the micropump can manually adjust the output flow of each stroke. The pressure switch can be selected according to the actual situation to detect the source pressure and the oil pressure, and give a chain alarm signal when the pressure is lower than the set value. The tank level switch monitors the tank level and triggers an alarm at low levels. The modular design makes the system extremely adaptable and easy to increase and decrease the number of lubrication points. The adaptability of the device can be further extended by the use of an external controller. High-tech applications enable the lubrication unit to be self-contained, easy to install and simple to adjust.


The Spiral Concentric Tube Installation is an economical dual-channel oil and gas lubrication unit developed according to the customer's actual needs. The Sprite concentric tube device mainly includes the following functions:

1. Adjustable oil supply: The adjustment of the oil volume per unit time of the unit is the frequency + single oil supply adjustment mode, that is, the oil supply frequency and the single oil supply amount can be set. Get the oil output per unit time.

2. Quick response: The special structure of the Scheper concentric tube device (oil and gas separately transported) avoids the shortcomings of long response time, and its application has also been expanded;

3. The lubricant consumption is greatly reduced;

4. Improve the working beat;

5. Better surface finish of the workpiece; 6. Flexible and light: The Scheper concentric tube device is small in size and can be used in a small installation space.

7. Strong equipment stability: The device is powered by compressed air, with few moving parts, small maintenance and strong stability.
