Abstract
The invention discloses a frequency-conversion constant-voltage control system of an emulsion pump. The frequency-conversion constant-voltage control system of the emulsion pump is composed of a frequency converter, a permanent-magnet synchronous motor, a speed reducer, the emulsion pump and a pressure sensor. The output end of a power supply of the frequency converter is connected with the input end of a power supply of the permanent-magnet synchronous motor. A power output shaft of the permanent-magnet synchronous motor is in transmission connection with a power input shaft of the emulsion pump. A liquid discharging opening of the emulsion pump is communicated with a liquid supply pipeline of a coal mine supporting device. The pressure sensor is arranged at a liquid discharging pipe opening of the liquid supply pipeline. A signal output end of the pressure sensor is connected with a control signal input end of the frequency converter. The frequency-conversion constant-voltage control system of the emulsion pump has the advantages that the frequency-conversion constant-voltage control system which is stable and reliable in operation performance and obvious in energy-saving effect is utilized by an emulsion pump station, and the service life of the emulsion pump and a liquid conveying pipeline is prolonged.
Description
Technical field
The present invention relates to the automatic feeding technology of emulsified liquid, especially relate to the emulsion pump frequency conversion constant voltage control system.
Background technique
Emulsion pump is the corollary equipment of support apparatus in coal mine such as hydraulic support, for support apparatus provides pressure, is the power source of support apparatus.Traditional working method is: after energising, emulsion power pack is namely rotatably supplied with emulsified liquid, no matter whether support apparatus needs fluid injection, emulsion power pack all turns round with rated speed.The emulsified liquid of confessing during not fluid injection returns in the emulsified liquid liquid tank by unloading valve, this process has not only been wasted electric energy, increased the mechanical wear of pump, make liquid-transport pipe-line after energising, be subject to the working life that pump and pipeline have been shortened in large impact always, and the temperature of emulsified liquid is raise, reduce the safety coefficient of support apparatus.
Summary of the invention
The emulsion pump frequency conversion constant voltage control system that provides a kind of power consumption low is provided the object of the invention.
For achieving the above object, the present invention takes following technical proposals:
Emulsion pump frequency conversion constant voltage control system of the present invention, be comprised of frequency variator, permanent magnet synchronous motor, retarder, emulsion pump, pressure transducer; Described converter power supply output terminal is connected with the power input of described permanent magnet synchronous motor; The permanent magnet synchronous motor pto＝power take-off is in transmission connection by the power input shaft of retarder and described emulsion pump; The liquid port of emulsion pump is connected with the feed liquid pipeline of support apparatus in coal mine; Described pressure transducer is arranged on the fluid mouth of pipe position of described feed liquid pipeline, and the signal output part of pressure transducer is connected with the control signal input end of frequency variator.
Beneficial effect of the present invention is mainly reflected in: emulsion power pack takes the frequency conversion constant voltage control system ride quality reliable and stable, and energy-saving effect is obvious.And improved the working life of emulsion pump and liquid-transport pipe-line.
The accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Embodiment
As shown in Figure 1, emulsion pump frequency conversion constant voltage control system of the present invention, be comprised of frequency variator, permanent magnet synchronous motor, retarder, emulsion pump, pressure transducer; Described converter power supply output terminal is connected with the power input of described permanent magnet synchronous motor; The permanent magnet synchronous motor pto＝power take-off is in transmission connection by the power input shaft of retarder and described emulsion pump; The liquid port of emulsion pump is connected with the feed liquid pipeline of support apparatus in coal mine; Described pressure transducer is arranged on the fluid mouth of pipe position of described feed liquid pipeline, and the signal output part of pressure transducer is connected with the control signal input end of frequency variator.
Working principle of the present invention is summarized as follows:
The abutment pressure of the pressure transducer Real-time Collection support apparatus in coal mine by being arranged on feed liquid pipeline fluid mouth of pipe place, and the force value that this pressure signal feeds back to frequency variator and setting is compared to i.e.: the force value of the force value of pressure transducer Real-time Collection-setting; When comparison value was less than 1, the frequency variator output frequency improved, and the rotating speed of controlling permanent magnet synchronous motor output progressively improves; When comparison value was greater than 1, the frequency variator output frequency reduced, and the rotating speed of controlling permanent magnet synchronous motor output progressively reduces.Thereby reach: when support apparatus in coal mine needed fluid injection, emulsion pump work provided hydraulic coupling to guarantee production; When the needs reservoir quantity was large, the rotating speed of emulsion pump improved; When needs reservoir quantity hour, the rotating speed of emulsion pump reduces.Frequency variator changes output frequency control emulsion pump rotating speed in real time according to the signal of pressure transducer in the course of the work, and then changes the abutment pressure of support apparatus in coal mine, and actual support pressure is approached to the target pressure value of setting.
