As shown in FIG. 4, a plurality of steel rings are arranged in the compression bellows 24 to enhance the strength of the compression bellows.
As shown in fig. 2 and 3, the surface of the auxiliary shrink slip 19 is coated with a smooth wear resistant coating.
The water inlet 31 is connected with a water inlet pipe, and the water outlet 13 is connected with a water outlet pipe. The adjusting motor 53 is controlled to start according to the desired water outlet intensity, the worm 54 connected with the output end of the adjusting motor 53 drives the worm wheel 55 to rotate, so that the swinging head 11 is driven to rotate to adjust the angle, and the worm wheel 55 and the worm 54 are matched with each other to be self-locked to prevent the swinging head 11 from being deflected by the impact force of water.
After the swing head 11 is adjusted, the power motor 41 starts to work after being started, the output shaft 18 drives the driving gear 34 to start to rotate, the driving gear 34 is meshed with the driven gear 17 and rotates, the driven gear 17 drives the driven shaft 15 to rotate, the driven shaft 15 drives the driven turntable 14 to rotate through a universal joint, the driving turntable 50 and the driven turntable 14 rotate to jointly drive the four water pumping pieces to rotate together, in the process that one water pumping piece rotates along with the driven turntable 14 for one circle, when the water pumping piece rotates to the farthest end of the driven turntable 14 and the driving turntable 50, the compression leather cavity 24 expands to suck water from the water inlet cavity 32 through the water inlet check valve 30, the compression leather cavity 24 is in a water filling state at the moment, and then continues to rotate to the closer end of the driven turntable 14 and the driving turntable 50 along with the rotation of the driven turntable 14; the compression leather chamber 24 contracts, liquid passes through the water outlet channel 60, then enters the water outlet chamber 33 through the water outlet one-way valve 22, finally flows out of the water outlet 13, and the four water pumping pieces continuously perform a water pumping process along with the rotation of the driven rotary disk 14. The design of the compression bellows 24 avoids the problem of water leakage of the conventional plunger pump once the plunger is worn due to the water pumping through the movement of the plunger, and the plunger is repeatedly squeezed and easily damaged. Meanwhile, the arrangement of the porous telescopic rod 26 and the telescopic rod 25 ensures that the compression leather chamber 24 cannot generate large offset and has better strength.
When the oscillating head 11 rotates, the contact terminals 35 are abutted to enter the hydraulic chamber 38, and the spring 37 is compressed, so that the hydraulic oil in the hydraulic chamber 38 is conveyed to the two hydraulic tank outlets 61 through the hydraulic tank 57. Thereby promote two multistage telescopic link 47's output and stretch out, drive two shrink part upper portion sliders 58 and slide, shrink part upper portion slider 58 slides and drives supplementary shrink gleitbretter 19 and slide together, and the cooperation of shrink part middle part spout 48 and shrink part middle part slider 39 has guaranteed supplementary shrink gleitbretter 19's intensity simultaneously, can not take place the swing.
After the position of supplementary shrink gleitbretter 19 is fixed, when the compression leather chamber 24 of every pump water spare rotate to with supplementary shrink gleitbretter 19 contact, supplementary shrink gleitbretter 19's camber radian sets up the fold end that makes compression leather chamber 24 and removes along the one side of supplementary shrink gleitbretter 19 for the fold in compression leather chamber 24 leans on tightly gradually, thereby carries out the shrink pump water through supplementary compression leather chamber 24 of supplementary shrink gleitbretter 19. The auxiliary contraction sliding sheet 19 effectively ensures the contraction of the compression leather chamber 24, and further prevents the compression leather chamber 24 from deforming.
The liquid transmission quantity can be controlled by the up-and-down swing of the water outlet cavity shell 12, the spring 37 in the hydraulic cavity 38 is always in a compressed state, when the water outlet cavity shell 12 swings downwards, the swing head 11 swings downwards along with the water outlet cavity shell, the liquid pressure in the hydraulic cavity 38 is reduced, so that the liquid pressure in the hydraulic groove 57 is reduced, the auxiliary contraction sliding piece 19 moves leftwards, otherwise, when the water outlet cavity shell 12 swings upwards, the swing head 11 swings upwards along with the water outlet cavity shell, the liquid pressure in the hydraulic cavity 38 is increased, so that the liquid pressure in the hydraulic groove 57 is increased, the auxiliary contraction sliding piece 19 moves rightwards, and the middle supporting block 49 and the auxiliary contraction sliding piece 19 are in sliding connection in the contraction part middle sliding groove 48 through the contraction part middle sliding block 39, so that the compression is more stable and efficient.
The compression leather chamber 24 is fixed on the water outlet channel interface 21 and the water inlet interface 29 through the locker 23, so that the maintenance cost is reduced, and the replacement is convenient. The whole inlet and outlet gap is large, the friction pair is few, the blockage is not easy, the sealing performance is stronger, and the maintenance is convenient.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
