Spring loaded regulators are used primarily for standard drilling operations and are designed to automatically return to their position at the end of every drilling cycle.
With the RB spring return regulator, the piston rod is automatically returned to its original position by the built-in spring when the piston rod is no longer loaded.
|Model||Max stroke||Load range||Adjusting range of speed||Impact energy permitted||Weight(Basic body)|
|Spring return type||mm||N||mm/sec||J||Kg|
|RB-3140||40||500-3,000||F=200N 0.1-10 F=1,500N 0.2-25
F=2,300N 0.3-35 F=3,000N 0.3-35
Purros Machinery also have other models (Maximum Stroke:12-100mm, Load Range:120-3000n, Withstand Impact Energy:2.3-3.5j)
Purros Precision Hydro Speed Regulator is a kind of hydraulic type control device of feed speed that can adjust freely feed speed of air cylinder from low speed to high speed within the range of expectation. Ways of control includes spring return type; you can make a choice according to your requirements.
The piston rod will return to an original position autormatically when discharge the load of piston rod of hydraulic damper Model RB.
1. Compact structure, direction of installation is free.
2. Adopt full-sealed structure that isn’t required to fill with work oil; it can keep long-time and stable control function.
3. Quick load change only causes little change of control speed, it can get stable feed speed.
4. Feeding speed can be easily adjusted by speed control button.
