PZ90 Hydraulic Disc-brake with API standard for JZ90 oil & gas drilling rig brake system
Product Features:
With double brake and enough storage brake torque, reliable and safe. With emergency manual pump and energy accumulator to make sure continue operating and safety braking when power off in the drilling site. Idiot-proof space rectify tongs, it’s convenient and accurate to adjust space to make brake reliable, steadily and sensitively. The structure of brake tong is special, the brake pad can be separated from brake disc quickly and accurately, also the friction calorie is few, and the effective of operation is high. Hydraulic circle is simple, stoppage is few, operating durable and reliable. The combined HPU is used mechanic-electronic-hydraulic integrated design; alarm and control are all automatic. The size is small and the weight is light. Humanization design, driller can master and operate easily and convenientl |
