Drive Head

Ground driving device of hydraulic brake device is introduced
Ground driving device of hydraulic brake device: stop pumping rod reversal, clutch gear drives the hydraulic pump operation pressure, the brake device brake, sucker rod or stop being transferred, the hydraulic pump does not move the brake release, so that the sucker rod reverse, brake, turn or not is still play a role. Repeated operation, brake, stop, until the sucker rod reverse torque automatic release date, brake stop action, automatic release reverse torque; brake speed can be adjusted by adjusting the pressure of the one-way valve has the advantages of simple operation, improves the safety and reliability of operation. The brake mechanism adopts car brake structure for wheel type structure, stable and reliable, the patent number: zl2012 20707349.5
