Embodiment
According to the figure, motor 1 is installed in the gear-box 3 of the pump housing by motor flange 2, side at gear-box is provided with pouring orifice 9, side at the pump housing is equipped with adjusting knob 4, and acts on connection by rotary knob rod mutually with stroke chamber 5, and the stroke chamber fixes by stroke chamber fixing bolt 10 and the pump housing one side, side in the stroke chamber is connected with diaphragm pump 6, its downside is provided with liquid sucting port adpting flange 8, and upside is provided with liquid outlet adpting flange 7, is provided with pump seat 11 at the downside of the pump housing.
Wherein, motor shaft 1.1 interts in mechanism case 3, pressure bearing 1.2 is installed on the motor shaft, the lower end of axle is provided with generator shaft gear 1.3, and be meshed with cam wheel 1.4 on being installed in camshaft 1.7, cam 1.8 is installed on the camshaft, and the upper and lower end of cam position is installed in respectively on camshaft bearing 1.5 and the camshaft bearing 1.6; Contacting with cam is with back-up ring 5.2 on the pull bar 5.1 that is connected, and is set with power spring 5.3 between back-up ring and barrier film 6.1; Be provided with diaphragm plate 6.2 in the relative one side of barrier film, form diaphragm cavity 6.3 between barrier film and the diaphragm plate; In the liquid sucting port in the liquid sucting port adpting flange that is connected with diaphragm pump liquid sucting port one-way valve 8.1 is installed, liquid sucting port one-way valve 7.1 is installed in the liquid outlet in the liquid outlet adpting flange; Adjusting knob 4 is connected with rotary knob rod 4.1, and the point of adjustment 4.2 on rotary knob rod and the pull bar fixes.
The utility model working procedure
Motor is meshed with cam wheel by generator shaft gear, give camshaft with power transmission, because cam is installed on camshaft, along with the rotation of cam produces eccentric motion, the height point of cam promotes pull bar to a side displacement, with length of spring compressed, make barrier film produce deformation thereupon, in diaphragm cavity, advance, dwindled the volume of diaphragm cavity, at this moment, liquid in the diaphragm pump is squeezed, and discharges by the liquid outlet one-way valve, when cam runs to small end, be subjected to the return effect of spring, barrier film is pulled, at this moment, because the effect of liquid outlet one-way valve, in diaphragm cavity, produce negative pressure, liquid injects liquid from liquid sucting port by the liquid sucting port one-way valve in diaphragm cavity, produce suction, finishes the one action process, and so forth, realize the effect of uninterrupted pumping liquid.
Because cam is a non-circular structure, has convex surface and concave surface, so it is reciprocating to promote pull bar.Because the radius of curvature of cam changes, so by regulating the distance between pull bar and the cam, then the pull bar stroke is changed, and will produce flow and pressure controlled effect.
