Prismatic drill rod refers to prismatic tapered drill pipe used for coal tunnel exploration, also called triangular drill pipe, anti sloughing hole drill pipe, ABS pipe. With prismatic steel pipe as rod body and thread or hex or square joint as connection type, it is manufactured by the friction welding craft. Prismatic drill rod pipe is widely used in the coal seam and similar geological conditions for coal mine water exploration and gas drainage borehole construction, and can also be used in anchorage and drilling in the field of geophysical prospecting and construction of water conservancy engineering.

K Series are multi-way rotary joints designed for middle and high speed high-pressure applications. They are used on machining center revolving tables, hydraulic workstations, coiling machines, wind generators, centrifugal machines and etc. ial carbon steel. If other material is required, please inform beforehand. Main Features: Supported by double high-precision maintenance-free bearings for high stability. Special sealing structure designed for high-speed and high-pressure application that provides prolonged failure-free operation. Low rotation torque. Special structure to be free from friction heat under high speed. Running torque unaffected by working pressure and temperature change. Max working speed up to 6500RPM. Drainage hole design to avoid exterior contamination. Customization available for different customer applications. Technical Ratings Max Speedï¼?6500 r/min Temperatureï¼?-30ï½?+80 Max Pressureï¼?30Mpa Mediaï¼?Hydraulic Oil Notes: 1.K Series use labyrinth sealing structure. During installation and operation, the drainage hole L must be connected by oil pipe to the oil collection tank. And the oil pipe must not be blocked to avoid back-pressure. 2.Inner leakage is allowed between each passage. Please pay attention to the compatibility of different working media to avoid crossed contamination. 3.The working fluid or hydraulic media should be filtered before being ued. The filtration precision should be no lower than 10um. 4.Working temperature rise will reduce the viscosity of the working fluid to increase the leakage volume. So during operation, cooling device should be accompanied. 5.The hydraulic system should be equipped with automatic pressure regulator to compensate the pressure loss caused by inner leakage.
The RF/DF mechanical chuck is designed with three large external sliding chunks, while it uses the cam structure inside. The expansion of the sliding chunks is done by the pushing of the cam structure, and the expanding sliding chunks then tighten the paperboard core and realize self-centering. Main features: Shaftless design for quick and efficient reeling and unreeling. Excellent paperboard core holding and tightening realized by the sliding chunks with large contact area and high stability, to avoid problems such like slipping, loosening, core breakage and etc. The locking force reinforced by special convex-concave texture of the sliding chunks. The cam structure provides even clamping force by use of self-weight. Maintenance-free structure with low friction force. Special excellent alloy steel material is adopted with great durability for high load capacity. Excellent paperboard core holding and tightening realized by the sliding chunks with large contact area and high stability, to avoid problems such like slipping, loosening, core breakage and etc.
