Aluminium volume baling press send volume trolley hydraulic device in, due to production line is longer, need by aluminium roll up with compared with
Fast speed is delivered to from packing apparatus from farther away place, when close at packing, need to switch at a slow speed with prevent aluminium volume by
Packing apparatus is knocked in excessive velocities.Trolley typically now is directly driven using variable-frequency motor, this just needs selected motor function
Rate is very big, but the driving moment of present motor is small, and occupied space is big, and overall device use cost can be made to increase.
Utility model content
Purpose of the utility model is to solve the above problems and provide a kind of achievable multistep speed regulation, driving moment is big, accounts for
The plunger pump speed regulating control hydraulic device of volume trolley is sent with small, the at low cost aluminium volume baling press in space.
To achieve the above object, the utility model provides the following technical solutions:
A kind of aluminium volume baling press send the hydraulic device of volume trolley, including plunger pump, overflow valve, the first solenoid directional control valve, the
One speed governing valve, the second speed governing valve, remote pressure regulating valve, check valve, the second solenoid directional control valve, hydraulic cylinder, it is characterised in that: the column
The oil outlet of plug pump is separately connected the main oil inlet of overflow valve and solenoid directional control valve, and the work oil inlet of the first solenoid directional control valve is logical
It crosses check valve and is connected with the first speed governing valve, work oil return opening is connected with the second speed governing valve by check valve, the first speed governing valve and the
The other end of two speed governing valves is connected with remote pressure regulating valve and check valve by Common Ducts, wherein the check valve other end and the second electricity
The main oil inlet of magnetic reversal valve connects, and the work oil inlet of the second solenoid directional control valve and rodless cavity one end of hydraulic cylinder connect, work
The rod chamber one end for making oil return opening and hydraulic cylinder connects.
Further, damping unit is equipped in the pipeline before the remote pressure regulating valve.
Further, the damping unit is the damping cloth of thickness 0.8mm.
Further, the plunger pump is constant pressure and constant flow plunger pump.
Further, the remote pressure regulating valve is small flow pressure regulator valve.
Compared with prior art, the utility model has the advantage that
The plunger pump speed regulating control hydraulic device of the utility model makes to lead to by adjusting the first speed governing valve or the second speed governing valve
The hydraulic oil for crossing the outlet of constant pressure and constant flow plunger pump and the outlet of the first speed governing valve generates certain pressure difference, so that constant pressure and flow
It measures plunger pump and progress constant flux control is damped by 0.8mm, is i.e. flow needed for real work is equal to constant pressure and constant flow plunger pump institute
The flow of confession, no any extra flow is by overflow valve overflow, the selected work general power also function according to needed for real work
Rate selects, and without losing extra power, and this hydraulic device driving moment is big, occupies little space, save the cost.
