- Third is lowering cable. Close drum jaw clutch, release drum brake and operate manual directional valve handle to lower cable.
- Fourth, after lowering cable, tighten drum brake, release drum jaw clutch.
What are practical test methods of testing system efficiency?
- First, connect output terminal of cable with oil cylinder piston rod ring on fixed bearing. And tension sensor is connected between them.
- Second, use another oil pump, adjust safe valve pressure and system controlling pressure. Start oil pump and adjust the pressure little lower than needed pressure.
- Third, complete above steps, and start the drum, observe and make records, when tension sensor approaches needed pressure, put hydraulic directional valve on middle position. If tension sensor can’t approach needed pressure, adjust the oil cylinder pressure to meet the standard that tension session approaches needed pressure.
- Fourth, measure oil cylinder pressure, and converse it into tension. The ratio between oil cylinder tension and drum tension is the efficiency of testing system.
