Description
Technical field:
The utility model relates to a kind of AC and DC dual-purpose high voltage cleaning machine.
Background technology:
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 machine by ac power supply, and the electronic high-pressure hydraulic pump of direct current machine 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 that a kind of AC and DC dual-purpose high voltage cleaning machine will be provided, and hands over to adapt to respectively, and two kinds of different electrical power of direct current are carried out operate as normal.
A kind of AC and DC dual-purpose high voltage cleaning machine of the present utility model, comprise electric supply installation, direct current machine and the high-pressure hydraulic pump that drives by direct current machine, it is characterized in that: described electric supply installation is provided with external power input, AC/DC rectification circuit, filter circuit, diverter switch and direct current machine 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 diverter switch, the movable end of diverter switch is connected with the direct current machine feeder ear, and the normal-closed end of diverter switch is connected with the external power input.
Under the situation that has storage 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 machine drives high-pressure hydraulic pump work.
When power supply was alternating current, the user can make the movable end of diverter switch be connected with the Chang Kaiduan of diverter switch, and AC power then becomes DC power supply by AC/DC rectifier and filter circuit and powers to direct current machine.
Another kind of AC and DC dual-purpose high voltage cleaning machine of the present utility model, comprise electric supply installation, alternating current machine and the high-pressure hydraulic pump that drives by alternating current machine, it is characterized in that: described electric supply installation is provided with external power input, DC/AC inverter circuit, diverter switch and alternating current machine 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 diverter switch, the movable end of diverter switch is connected with the alternating current machine feeder ear, and the normal-closed end of diverter switch is connected with the external power input.
When power supply was storage battery, the user can make the movable end of diverter switch be connected with the Chang Kaiduan of diverter switch, and DC power supply then becomes AC power by the DC/AC inverter and powers to alternating current machine.
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.
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 machine.In Fig. 1, K is a diverter switch among the figure.During normal the use, external power is a DC power supply, 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 diverter switch, the movable end of diverter switch is connected with motor power supply output, and the normal-closed end of diverter switch is connected with the external power input.At this moment, diverter switch is connected " DC " position, and direct current machine is directly by the external power powered operation.When external power will use AC power, diverter switch was connected " AC " position, and external power becomes DC power supply by AC/DC rectifier and filter circuit and powers to motor.
Fig. 2 is the embodiment that is applicable to alternating current machine.In Fig. 2, K is a diverter 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 diverter switch, the movable end of diverter switch is connected with motor power supply output, and the normal-closed end of diverter switch is connected with the external power input.At this moment, diverter switch is connected " AC " position, and alternating current machine is directly by the external power powered operation.When external power will use DC power supply, diverter 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 creation level height has bigger application value.
