Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation (perspective view) of this utility model valve body;
Fig. 3 is control structure schematic diagram of the present utility model.
Detailed description of the invention
The utility model will be further described with embodiment below in conjunction with the accompanying drawings.
This utility model is a kind of use dedicated servo pump in injection machine, and existing servopump is mainly by adjusting
Servomotor rotating speed realizes the flow to hydraulic oil and pressure adjusts, and it relies primarily on reflux inlet to control output flow and pressure
The flow that power, the servopump of the most this structure, servomotor and flow hydraulic pump provide typically will be more than required hydraulic pressure
Oil flow, therefore energy consumption is the highest, and to flow and the precision of real time control of pressure when of use, is not the most accurate.
As shown in Figure 1, proposing the servopump of a kind of new structure in this utility model, this servopump is structure as a whole injection machine servo
Pump, main technological improvement is: described servopump is by assembling shell 1, valve body 4, servomotor 2 and flow hydraulic pump 3 groups
Becoming, the cylindrical shell that assembling shell 1 is closed for one end, servomotor 2 arranges and is arranged on inside assembling shell 1, flow hydraulic pressure
Pump 3 is fixed on valve body 4, and this flow hydraulic pump 3 is connected with servomotor 2, and utilizes servomotor 2 power to be operated. as
Shown in Fig. 2, valve body 4 is fixed on outside assembling shell 1, and the one side that valve body 4 is connected with flow hydraulic pump 3 is provided with and flow liquid
The runner 5 matched on press pump 3, valve body 4 is additionally provided with on another one surface the runner 5 matched with fuel feed pump, arranges
On valve body 4, the runner 5 on two surfaces is the most corresponding and connects.It is provided with assembling shell on two surfaces on described valve body 4
Body 2 and flow hydraulic pump 3 fixing screwed hole or through hole 6.Valve body 4, as an intermediate, carries firm discharge hydraulic pressure
Pump 3 and connection in-line, and above-mentioned parts are fixed on the task on assembling shell 1, pass through
Above-mentioned multiple parts are integrated into an entirety, cleverly by servomotor 2, assembling by the setting of valve body 4 parts
Housing 1, flow hydraulic pump 3 and valve body 4 are fixed as one integrally-built device, not only effectively reduce the volume of equipment,
With the stability and the reliability that significantly improve equipment.Described flow hydraulic pump 3 is without backlash dosing pump.
As it is shown on figure 3, this utility model is in order to improve the servo-driver accuracy to flow-control, described servo is driven
Dynamic device is connected with servomotor 2, and controls pressure and the flow of servopump by controlling the rotating speed of servomotor 2, here may be used
To be interpreted as that the first step controls program, generally the setting of this rotating speed is according to servomotor 2 rotating speed and flow hydraulic pressure
The preset value of pump 3 and set, described servopump is provided with flow transducer, also commonly referred to as encoder, is used for feeding back
The flow information produced during servo operating.After servo-driver receives the signal of flow transducer, this signal is carried out point
After analysing and contrasting with requirements, the rotating speed of servomotor 2 is finely adjusted, to guarantee that output flow is more nearly requirements.
This process is to adjust in real time, namely relies on the flow information adjusting servomotor 2 rotating speed and receiving, ensures stream as far as possible
Value is close with requirements. and it is second step namely real-time trim process here. followed by the 3rd step, the most further
Accurately adjust process. side is set at described flow hydraulic pump 3 and is fixed with flow adjuster, described flow adjuster
In be provided with the pressure transducer for feedback pressure, described pressure transducer by pressure signal transmit to servo-driver.
After two above-mentioned successive step, it is seen that pressure and flow value in pipeline are the least with the deviation of requirements, are pressed by design
After force transducer, force value is transferred to servo-driver, and this force value is directly to measure the pressure arrived, therefore pass through
Servo-driver carries out adjustment of rotational speed again so that it is can ensure that the force value in pipeline is basically identical with requirements accurately.
This utility model is intermediate by above-mentioned valve body 4 structure, coordinates scientific and reasonable three time adjustment of rotational speed simultaneously, the most permissible
Ensure output and flow and the concordance of pressure requirements of servomotor 2, avoid usual servomotor 2 rotating speed too high, logical
Crossing pressure and the mode of flow in reflux inlet control piper, therefore compared with traditional control mode, this utility model obtains
Although significant energy-saving effect. in this utility model, there is the setting of reflux inlet, but this reflux inlet effect is the least, Jin Jinti
Adjusting for pressure when special operation condition and unit exception and flow, therefore reflux inlet is only that one is mended in this utility model
Fill measure.
The installation that carried out by above-mentioned servopump for convenience is fixed, on the assembling shell 1 described in this utility model
It is provided with the fixing seat 7 fixing with equipment, this fixing seat 7 is provided with fixed via.
Described above is only preferred embodiment of the present utility model, and above-mentioned specific embodiment is not to this utility model
Restriction.In technological thought category of the present utility model, various deformation and amendment, the ordinary skill of all this areas can occur
Retouching, amendment or the equivalent that personnel are made as described above, belongs to the scope that this utility model is protected.
