Structure and features
This hydraulic clamps machine adoptshyperboloid roller-climbing clamping mode.Two slope plates installeddislocation form the hyperboloid, four jaw plates are proportional distributedwith 90 degree. Frictional belt drives the jaw plates to clamp the pipes, andevery plate has 4-6 teeth to make sure it has 16-24 clamping points. Thisstructure has features of large clamping range, high strength, steady tighten,no slipping, no damage for pipe and clamping scar according to API standard. Thebackup clamp adopts pneumatic clamping with high automation.
Adopts split-body structure and isinsisted of driving clamp, backup clamp, machine body, torque testing device, hydraulicpower supply, electric control system and computer system.In screwing on, thedouble-pump change speed automatically, screwing on in high-speed, torque on inlow speed, not only to improve efficiency, also in line with API standard.
Its operation system (including:operation carbinet,computer and software , etc.)according to the standard of Q/HBSJ02.01-2009. Andsupply one jaw plate ,one teeth (see table) , one manual instruction, one pressure - torque table.
