5. Operation
5.1 Inspect Hydraulic power
●
Ensure 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.
5.2.
Connecting Hydraulic oil hoses
5.3.
Clean the coupling unit before connect Hydraulic oil hoses.
●
Don’t connect or remove oil hoses until switch off the control valve of hydraulic
oil. If not,may lead to damage of coupling unit or high temperature of hydraulic oil.
●
Connect return hoses firstly, then inlet hoses.
●
Attention:the high temperature which caused by unconnecting hydraulic hoses
exposed to sunshine will lead to pressure increasing in the hydraulic tube,this will
make more difficult connecting, connect free-end of hydraulic oil tube together.
5.4. Pump
operation
●
Pay attention to all safety information.
●
Ensure no dreg in the pump inlet port, clean the dreg according with clean
specification.
●
Connect one water pipe sized 3 inch to pump discharge. Shorter water pipe
which meet request,more efficient. Located the water pipe, avoid to cause bend or
cross
●
Fasten the rope or chain to the lift ring on top of pump,then immerse the
equipment into pumped liquid slowly. Don’t lift or lay down pump with hydraulic
oil tube to prevent the damage of tube or coupling unit.
●
Switch on hydraulic power(No damage for pump with no-load operation )
●
Switch off power firstly to stop pump movement. Lifting the pump through the
rope which fastened to lift ring.
●
Warm-up hydraulic oil at low engine running speed when the equipment
worked under cold weather. The temperature of hydraulic oil should be
≥
10°C
before used normal oil.
