Detailed Description
The invention is explained in further detail below with reference to the figures and the specific embodiments.
As shown in fig. 1-2, a portable single hydraulic prop fast liquid adding device comprises an air supply pipeline 1, an air source pipe 2, a portable booster pump 3, a liquid supply tank 4, a liquid suction pipe 5, a liquid supply pipe 6, a connecting valve 7, a liquid injection gun 8, a three-way valve 9 and a hydraulic single body 10, and is characterized in that: air supply pipe 2 is installed outward to air supply pipeline 1, 4 external connections of liquid supply box have pipette 5, the emulsion has been placed in the liquid supply box 4, portable booster pump 3 installs with air supply pipe 2 and pipette 5 respectively, 3 outputs of portable booster pump are connected with feed pipe 6, feed pipe 6 is installed with two notes liquid guns 8 through connecting valve 7, it installs on hydraulic pressure monomer 10 through three way valve 9 to annotate liquid gun 8.
Portable booster pump 3 includes the pump body 11, air feed mouth 12, manometer 13, imbibition mouth 14, supplies liquid mouth 15, air feed mouth 12 is installed at the pump body 11 top, manometer 13 is installed to the pump body 11 top rear end, and the top surface mid-mounting has imbibition mouth 14, and top front side installs liquid feed mouth 15.

The working principle of the invention is as follows: when the pumping station starts to work, oil is sucked into the high-pressure oil suction one-way valve and the low-pressure oil suction one-way valve by the plunger and is pressed into the single hydraulic prop through the high-pressure oil discharge one-way valve and the low-pressure oil discharge one-way valve, and when the pressure rises to 1.5MPa, the low-pressure overflow valve is opened and the low-pressure oil overflows to the oil tank; the high pressure plunger continues to operate, with the pressure gradually increasing. When the pressure exceeds 11MPa, the high-pressure valve is opened, high-pressure oil overflows from the high-pressure valve and returns to the oil tank, and the pressure is always kept at 11 MPa.
The foregoing is a preferred embodiment of the present invention, and it will be apparent to those skilled in the art that variations, modifications, substitutions and alterations can be made in the embodiment without departing from the principles and spirit of the invention.
