The specific working process is as follows:
before the device is used for liquid pumping work, adaptive through pipes are inserted into the openings on the two sides, and after the adaptive through pipes are connected with the internal threaded pipe sleeve 14 through bolts, the left pipe is a liquid outlet pipe, and the right pipe is a liquid inlet pipe, so that preparation work is completed.
The torque motors 5 on the two sides are started, the output shafts of the torque motors 5 control the driving rotating gears 15 to rotate anticlockwise, the driven rotating gears 8 rotate clockwise under the meshing action at the moment, the pressure in the middle of the hydraulic tank 11 is small on the left side and strong on the right side under the rotating exhaust action of the two rotating gears, so that the liquid to be pumped of the liquid inlet pipe on the right side is pumped into the pump body 1 by the air pressure in the middle of the pump body 1 and flows out from the right side under the action of the pressure, and the liquid pumping effect is further achieved.
Under the rotation effect of two commentaries on classics gears, the commentaries on classics gear can take place relative friction with the inner wall of hydraulic pressure case 11, hydraulic pressure case 11 wholly has the electrostatic absorption effect this moment, and the electrically conductive frame 12 of both sides not only can play firm effect, prevent that pump body 1 from taking place not hard up when drawing liquid, and electrically conductive frame 12 can conduct the electric charge of hydraulic pressure case 11 inside to support in case shell 31 inside ground connection current conducting plate 32, the static of hydraulic pressure case 11 is eliminated to the electrically conductive effect of ground connection through ground connection current conducting plate 32, reduce the dust absorption effect of hydraulic pressure case 11.
When the torque motor 5 works, the transmission gear sleeve 6 rotates under the output rotation action of the torque motor 5, and then drives the rotation protruding rod 71 to rotate, when the rotation protruding rod 71 rotates to a horizontal state, the protruding head end of the rotation protruding rod 71 pushes the horizontal sliding rods 76 at two sides to the direction along the inner walls of the respective fixed pipe sleeves 78, at this time, the horizontal sliding rods 76 control the dial 75 fixedly connected to the outer surface to move, the dial 75 pushes the toggle baffle 73 above, the toggle baffle 73 rotates along the rotation supporting rod 72, and the top end of the hydraulic tank 11 is closed.
When the rotary protruding rod 71 rotates to the state shown in fig. 4, the horizontal sliding rod 76 slides to the middle of the hydraulic tank 11 under the thrust of the return spring 77, at this time, the toggle baffle 73 rotates to the vertical state, and along with the high-speed rotation of the torque motor 5, the dust collection device 7 feeds a dust collection fan above the hydraulic tank 11 into the hydraulic tank 11 through the high-speed rotation of the toggle baffle 73, and discharges the dust to the two sides of the hydraulic tank 11 through the guide blocks 13.
Because the device is in relative sealed state at the during operation, the inside drawing liquid condition is observed to the difficult outside, during the device drawing liquid, because the middle part has liquid to pass through, and liquid is during the process, the gravity of liquid can push down rubber soft cover 16, vertical slide bar 17 gliding this moment, the user can observe from the outside that remove driving lever 18 glides, the middle part that has liquid through hydraulic tank 11 is represented, drawing liquid is in process promptly, it resets to move driving lever 18 after the work is ended, it does not have the liquid to pass through to represent, can take off the siphunculus of adaptation this moment, the problem of drawing liquid and not discharging totally and lead to the liquid leakage has been avoided.
Because stir baffle 73 and can play certain fan-type radiating effect when high-speed rotating, so the whole radiating effect of the pump body 1 at the during operation is good, has effectively alleviated the heat dispersion of case shell and has reduced, can lead to inside gear part to be in the problem that work takes place ageing easily under the high temperature condition for a long time.
Because the driving rotating gear 15 is in a high-speed rotating state during operation, the driven rotating gear 8 can bear large torque force during driven rotation, so that the friction force between the hollow gear sleeve 82 and the torque rotating rod 81 needs to be reduced by the lubricating bearing 85, and because of the liquidity of liquid, the outer surface of the driven rotating gear 8 can be subjected to the impact force of the liquid during rotation, when the pressure is transmitted to the lubricating bearing 85 by the outer surface of the hollow gear sleeve 82 at the moment, the inner layer and the outer layer of the lubricating bearing 85 are mutually extruded, at the moment, the pressure is transmitted to the adjusting spring 93 by the small ball 84 through the small steel column 92, the adjusting spring 93 is compressed, the metal ball shell 91 is kept in a fixed state under the fixed action of the connecting arc plates 84 at two sides, and because the adjusting spring 93 plays a certain buffering role, the torque rotating rod 81 is not easy to bend during long-time operation.
