Axual-piston-piston-piston puppies-140/20 and NAPESL-140/20 with the right direction of rotation of the shaft are designed to pump the working fluid into the hydraulic systems of machine tools, presses and other machines with a hydraulic drive that requires the supply of flow and the possibility of flow reverse. < Br/>
NAPEL-140-20 pumps and NAPESL 140-20 are adjustable axial pistons with an end distribution of the working fluid, with electro-hydraulic control of two adjustable feeds on each cavity, with a variable direction of the flow of working fluid.
Passes are mounted on the paws, as evidenced by the literal “l” in the designation.
As a control node in the pumps of the NAPEL-140-20 model, a single-flow plate NPL NPL plate pump is 12.5/6.3 or a two-stroke NPL 16-32/6.3 for NAPESL-140/20 (letter “C” in the designation). Br/>
Changing direction
The flow of the working fluid from the plate pumps is carried out by a hydraulic spool distributor with a conditional passage of 6 mm (for example, hydraulic distributor 1re6).
When the control signal is supplied to one of the electromagnets of the hydraulic distributor, the operating cavity of the corresponding pusher of the control mechanism with the pressure line of the control pump and, as a result, the movement of the pusher to the length determined by the regulation of the regulatory screw. As a result, there is a corresponding turn of the bicarry lever and the associated crane-gold. In this position of the valve crane, the working fluid entering the pressure from the plate pump enters the chambers of the rotary hydraulic resort. The current torque, developing the hydroder rotor and the associated traverse of the axial piston unit.
The magnitude and direction of the rotation of the traverse determines the amount of the supply and direction of movement of the flow of the working fluid in the pumps of the NAPEL-140/20 and NAPESL 140-20.
