After meter, because its size is smaller, integral heat sink area also very little is easily overheated during high speed operation, carried using the present invention
After the scheme of confession, cylinder body can be cooled down well, so as to play a part of protecting high-pressure plunger pump.
The embodiment of the present invention is mainly used in miniaturization hydraulic test, especially Handheld high-voltage injection apparatus, such as hand
Hold formula high-pressure extinction equipment, Handheld high-voltage flushing device.
The foregoing is only a specific embodiment of the invention, but protection scope of the present invention is not limited thereto, any
Those familiar with the art the invention discloses technical scope in, the change or replacement that can be readily occurred in, all should
It is included within the scope of the present invention.Therefore, protection scope of the present invention should be defined by scope of the claims.
