4. Demand of Hydraulic power device
4.1 The flow range for hydraulic power device should be 26-34L/min, the range of
working pressure is 105-140bar. Advised safety pressure set at 145bar.
●
the pressure of return hoses ending should be less than 17bar,the range of
hydraulic oil viscosity should be 100-400ssu.
●
The temperature of hydraulic oil should be±60°C compared with work area
temperature when pump running.
●
Min.25mm filtration is requested for hydraulic power.
●
Water can’t be included in hydraulic, furthermore,don’t attempt to transform
emulsified liquid into hydraulic power medium.
4.2.
The min. working pressure of hydraulic oil hoses must be over 175bar.
●
inner surface of hydraulic tube should be with anti-permeability, outer surface
should be with abrasive resistance.
●
Used hydraulic oil choses which marked insulation when worked in the cable
area. Properly training is required for the operator. To keep the degrade of
insulation, keep the oil choses dry and clean.If not,it may lead to serious injury.
●
Don’t use hydraulic tube which is not allocated to the pump,improperly or
incorrect operation will result in tube broken and other problem.leaked hydraulic
oil after tube broken could rip into body,lead to personal injury
●
Never crossed hydraulic oil hoses, and leave the hoses far away from high
temperature and sharp soild.
●
Use different length oil hoses according with below list. Avoid to use the
connected hoses by quick coupling(2 or more shoter hoses connected into
required length)
