The JZW type thread pile driver is designed to have a hole depth of 24 meters. The hole shape is different from that of a conventional long auger drill. It is threaded (equivalent to one internal thread), and the long auger drill has a cylindrical shape. Compared with the cylindrical hole, the thread-like hole will double the bearing capacity, greatly reduce the amount of concrete poured, reduce the construction cost, and have broad market prospects.
The JZW type thread pile driver has obvious advantages and the production difficulty is much more than that of the long screw pile machine. Because in order to leave a complete threaded pile machine hole in the soil layer, it is necessary to synchronize the rotation speed of the drill pipe with the speed of the falling (or rising) to ensure that the thread is formed, otherwise the thread will be completely destroyed. In response to this technical problem, Fangyuan Group adopted the method of frequency conversion speed regulation to achieve the synchronization requirements.
PP Spunbond Nonwovens Production Line
The width of the product is 2.4m, the gram weight is 12g / m2, and the monofilament size reaches 2.1-2.2. It is mainly used for film backing and water absorbing material coating of diapers. Although the gram weight is low, the cloth surface is uniform, which can ensure that the backing film is impermeable, so it is favored by downstream users.
Main technical features
1. S die is made of coat hanger pipe melt distribution spinning, CAD / CAM technology, no dead angle, no retention, short transition time, uniform spinning in full width, no broken ends at both ends.
2. The inner wall of draft air duct is made of stainless steel mirror plate with high flatness and good trafficability. The width of upper and lower draft air duct can be adjusted as a whole.
3. AC variable frequency speed regulation, full digital communication synchronization, convenient for user maintenance. High degree of automation, man-machine control interface is conducive to production management, stable and reliable performance.
According to different product requirements, equipped with different speed series of rolling mill, winding machine. The rolling point is uniform, the constant tension automatic control unit and slitting function of the roll machine belt, and the coil distribution is appropriate, uniform and neat.
