Dynamicization control, improves automation degree of equipment.
The specific work process and working principle of the utility model are as follows:
100T metal packing hydraulic press governor oil pump electricity Unit Selection: servo motor 1 uses Ai Sidun servo motor
EMB-2FDRA21+Pronet-3ZDIB, crescent gear pump 2 use Hai Teke inner tooth pump HG1-50-01R-VPC.Servo motor
Rated speed is 1800r/min, and maximum speed is 2000 r/min, and it is 100L/min that electrohydraulic servo system, which exports maximum stream flow,
Higher than tradition with tonnage baling press output flow.Automatically controlled type selecting: touch screen 13,12 analog-to-digital conversion device of PLC controller, servo-drive
Device 11 and servo motor 1.
No-load standby, pressure release state: tradition is with the tonnage baling press cycle of operation about 120s, wherein being about for charge time
20s, in this 20s time, threephase asynchronous machine drives invariable power oil pump with rated speed rotation oil suction idle running oil return box.When pressure release
Solenoid valve commutation pressure release, this stage Oil pump electrical machinery group idle running oil return box, is equivalent to standby energy loss.Oil return pipe road binders when unloaded
Certain pressure loss, general no-load current account for the one third of rated current, about 0.2 when power factor is standby, at this time without
Function loss are as follows: P0=1.732UICOS φ=1.732*380* (18.5*2/3) * 0.2=1.7kW, and electrohydraulic servo system is in this rank
Section power consumption is zero.
State of pressure keeping: tradition rises to after specified pressure with tonnage baling press master cylinder pressure wants persistent pressure 3-4s, this section
In time, the high pressure oil that oil pump provides largely passes through overflow valve and flows back to fuel tank (small part is for pushing master cylinder), at this time oil pump
Variable, motor maintain invariable power, and power loss is close to motor rated power 18.5kW.And electrohydraulic servo system is in packing stage
When needing to maintain pressure maintaining, the leakage inside hydraulic system can meet that pressure is constant, this stage power consumption is very low, almost
Zero.
Pusher, compacting state: since tradition is 18.5kW with tonnage baling press power of motor, the initial pressure P of variable pump=
18.5*55/ (63*1.45)=11MPa is delivery work at this time, and when pressure is greater than 11MPa, invariable power plunger pump starts to become
Amount, flow becomes smaller at this time, and oil cylinder slows, maximum pressure 28MPa, and variable is than about 2.5, when load pressure is higher,
Oil pump flow output is lower, and minimum speed is about 0.4 times of maximum speed.And the flow of electrohydraulic servo system output is not by pressure
Change and change, can be run always with most fast speed.Finally, by calculating, 100T metal packing hydraulic press uses servo
After system, fractional energy savings are as follows: 35%-45%, improved efficiency 15%-25%.
Above-described embodiment is used to illustrate the utility model, rather than limits the utility model, practical at this
In novel spirit and scope of protection of the claims, to any modifications and changes that the utility model is made, this reality is both fallen within
With novel protection scope.
