Description
Technical field
The utility model relates to the clear Xian's machine of a kind of power of alterating and direct current dual-purpose high voltage.
Prior art
Present electronic high-pressure hydraulic pump all is single power supply power supply, can only be as: the electronic high-pressure hydraulic pump of alternating current generator by ac power supply, and the electronic high-pressure hydraulic pump of direct current generator just can only be by DC power supply.This will bring many inconvenience to the user in production application.
Summary of the invention
The purpose of this utility model is to provide a kind of AC and DC dual-purpose high voltage clear Xian's machine, hands over to adapt to respectively, and two kinds of different electrical power of direct current are carried out operate as normal.
The clear Xian's machine of a kind of AC and DC dual-purpose high voltage of the present utility model, comprise electric supply installation, direct current generator and the high-pressure hydraulic pump that drives by direct current generator, it is characterized in that: described electric supply installation is provided with external power input, AC/DC rectification circuit, filter circuit, change-over switch and direct current generator feeder ear, the external power input is connected to the input of rectification circuit, the output of rectification circuit is connected to the Chang Kaiduan that filter circuit is connected to change-over switch, the movable end of change-over switch is connected with the direct current generator feeder ear, and the normal-closed end of change-over switch is connected with the external power input.
Under the situation that has battery to power, the user can be directly be connected the power line of dry cell with the external power input, so that direct current generator drives high-pressure hydraulic pump work.
When power supply was alternating current, the user can make the movable end of change-over switch be connected with the Chang Kaiduan of change-over switch, and AC power then becomes dc source by AC/DC rectifier and filter circuit and powers to direct current generator.
The clear Xian's machine of another kind of AC and DC dual-purpose high voltage of the present utility model, comprise electric supply installation, alternating current generator and the high-pressure hydraulic pump that drives by alternating current generator, it is characterized in that: described electric supply installation is provided with external power input, DC/AC inverter circuit, change-over switch and alternating current generator feeder ear, the external power input is connected to the input of DC/AC inverter circuit, the output of DC/AC inverter circuit is connected to the Chang Kaiduan of change-over switch, the movable end of change-over switch is connected with the alternating current generator feeder ear, and the normal-closed end of change-over switch is connected with the external power input.
When power supply was battery, the user can make the movable end of change-over switch be connected with the Chang Kaiduan of change-over switch, and dc source is then powered to alternating current generator by becoming AC power by the DC/AC inverter.
Remarkable advantage of the present utility model is to control conveniently, and safe and reliable, result of use is good.
Description of drawings
Fig. 1 is the electric supply installation theory diagram of the utility model embodiment one.
Fig. 2 is the electric supply installation theory diagram of the utility model embodiment two.
The specific embodiment
Further specify operation principle of the present utility model below in conjunction with embodiment and accompanying drawing.
Fig. 1 is the embodiment that is applicable to direct current generator.In Fig. 1, K is a change-over switch among the figure.During normal the use, external power is a dc source, the external power input is connected to the input of rectification circuit, the output of rectification circuit is connected to the Chang Kaiduan that filter circuit is connected to change-over switch, the movable end of change-over switch is connected with motor power supply output, and the normal-closed end of change-over switch is connected with the external power input.At this moment, change-over switch is connected " DC " position, direct current generator is directly by the external power powered operation.When external power will use AC power, change-over switch was connected " AC " position, external power becomes dc source by AC/DC rectifier and filter circuit and powers to motor.
Fig. 2 is the embodiment that is applicable to alternating current generator.In Fig. 2, K is a change-over switch among the figure.During normal the use, external power is an AC power, the external power input is connected to the input of DC/AC inverter circuit, the output of DC/AC inverter circuit is connected to the Chang Kaiduan of change-over switch, the movable end of change-over switch is connected with motor power supply output, and the normal-closed end of change-over switch is connected with the external power input.At this moment, change-over switch is connected " AC " position, exchanges the stream motor directly by the external power powered operation.When external power will use dc source, change-over switch was connected " DC " position, and external power becomes AC power by the DC/AC inverter and powers to motor.
The utility model is novel, and is reasonable in design, and the innovation level height has bigger application value.
