YOTFJ/650/750/875 Series Speed Regulating Hydraulic Coupler Reverse Deceleration Box

This series product is the new hydraulic coupling reducer developed by our company for the solid control circulation system of drilling mud pump. The combination of fixed pipe oil discharge and inlet valve control is adopted to adjust the speed, which has the advantages of starting with load, overload protection, isolating torsion-vibration, reducing impact, stepless speed regulation and fast and steady clutch. It is the best choice for matching oil drilling mud pump.
