6. At present, the main pump of excavator mainly uses plunger pump, and its pumping mechanism is exactly the same as that of syringe pumping liquid
it is mainly composed of multiple plungers (generally odd, 9, and others), which are installed in the cylinder block (also called pump bladder) and evenly distributed along the axis in the same number of holes as the number of plungers. Then the slipper on the plunger is pressed on the swash plate with an inclined angle to the plane of the cylinder block
when the whole cylinder block rotates with the plunger, when the plunger rotates to the farthest distance from the swash plate to the cylinder block, a space will be drawn out between the plunger and the cylinder block. When the swash plate is closest to the cylinder block, the space between the plunger and the cylinder block is the smallest
it is equivalent that the same plunger moves back and forth between the corresponding holes when it is pulled out and inserted
as long as the valve plate is used, the oil suction port is configured to the corresponding position farthest from the swashplate to the cylinder block, and the oil discharge port is configured to the corresponding position nearest to the swashplate to the cylinder block. As long as the main pump rotates, it can realize continuous oil suction and discharge
the boom and the jib do not have the boom hydraulic pump and the jib hydraulic pump separately. They and other actions such as bucket, walking and slewing are provided by the same or two parallel or series pumps (some small excavators may use gear pump to supply oil for slewing)
its oil supply mechanism is that the oil is discharged from the main pump to the control valve (multi way valve, distribution valve, etc., whatever, just different names), and then through the switching control of the control valve spool (which may be pilot oil control, mechanical pull rod control, electromagnetic control, etc.), the pressure oil enters into different cavities of the boom or jib cylinder to push the piston movement of the cylinder, So as to push the big and small arms to move
for example, when the pressure oil enters the rod cavity of the oil cylinder (the extended end of the oil cylinder rod), the oil cylinder rod is recovered. If it is a small arm, it is shown as pulling the small arm outward (the model with the small arm oil cylinder installed above the big arm is different from other heterogeneous machines); If it's the big arm, it's the big arm descending
similarly, when the pressure oil enters the rodless chamber (the end of the cylinder barrel), the rod of the cylinder extends outward. If it is the small arm, it shows the recovery of the small arm, and the big arm shows the lifting of the big arm.

7. Yes
in the lower part of the pump, the pumping pipe is under negative pressure, and the delivery pipe above the pump outlet is under positive pressure; The submersible pump is under positive pressure from the delivery pipe above the pump. Therefore, the outlet pipe of the submersible pump can be connected to the outlet of the pump with a tee, which is shared by the water delivery pipe. But the tee connection is a bit of a hassle
if the outlet pipe of the submersible pump directly pumps the pumping pipe of the pump, and two pumps are connected in series, the water pressure height (water head) can be increased.

8. Normal 200 should be one pump body and two pump cores. A pump core drives a walking pump.. How are you going to pick it up... What's the purpose of driving three traveling motors? Is it a winch?? To be more specific, I'll give you a reference...
9. One pump and two domestic pressure tanks are connected in parallel, which is convenient for maintenance and repair.
10. It can be used together, but not at the same time, otherwise the pressure will be reced.
