FZ/T 93034-2017Cotton flyer roving frame (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard replaces FZ/T 93034-2006 "Cotton Spindle Roving Machine", compared with the main technical changes in FZ/T 93034-2006 as follows.

--- Modified specifications and parameters (see Table 1, 2006 version of Table 1);

--- Increased requirements for leaf spring pressurized cradle (see 4.1.5, 2006 version 4.1.5);

--- Modify the requirements of the transmission gear box or reversing gear box, worm gear box, differential box (see 4.1.7, 2006 version 4.1.7);

--- Modify the requirements of the radial runout of the common axis of the work surface of the bottom roller (see 4.3.1, version 4.3.1 of the 2006 edition);

--- Modify the upper roller pressure limit deviation requirements (see 4.3.2, 2006 version 4.3.2);

--- Removed the requirement for the contact spot of the spur gear pair (2006 version 4.3.7);

--- Modify the requirements for radial runout at the upper and lower ends of spindle bars (see 4.4.2, 4.4.3, 4.4.2 of the 2006 edition);

--- Increased security requirements (see 4.5);

--- Modify the requirements of electrical equipment (see 4.6, 2006 version 4.5);

--- Changed the blowing and suction device to the cleaning device, and adjusted and added corresponding provisions (see 4.7, 2006 version 4.6);

--- Modify the noise requirements (see 4.8, 2006 version 4.7);

--- Modify the request for a break rate (see 4.12, version 4.11 of the 2006 edition);

--- Modify the test conditions of the workload test [see 5.3.1d), 2006 version 5.3.1.4].
