Description

Rotator type manual pump

Technical field

The present invention relates to a kind of displacement pump, particularly a kind of manually-operated rotator type manual pump.

Background technique

In vast rural area especially in rich groundwater area, well water is still extensively drunk and is used, the simple and easy method of extraction well water is the hand pump without the need to electric power, existing manually-operated hand pump mainly hand displacement pump, it is by the pump housing, piston, handle and two one-way valve compositions, if application number is 96213343.4 patent applications being called " Full-closed piston-type double-action ", it is exactly the typical structure of hand displacement pump, for another example application number is that 87212190.U name is called that the patent of " deep well hand pump " also proposes the hand displacement pump of similar structure, for another example application number is that 86202009.U name is called in the patent application of " Universal manual diaphragm pump " structure proposing and replace piston with barrier film, but the operating method that its operating method and above-mentioned two pushes up patent is identical, all manually swing back and forth with handling handle to draw water, because the Amplitude Ratio swung is comparatively large, easily make people tired, meanwhile, no matter be piston or barrier film, operate each time, once, namely piston is single-acting, and water outlet is intermittent in a water outlet, propose two cover membrane configurations in the patent application of " Universal manual diaphragm pump ", improve water outlet interrupted defect, but it equals to have two cover pistons or barrier film and two covers and sucks, discharges one-way valve, virtually adds volume and cost, meanwhile, owing to there being one-way valve to exist, pump structure is complicated, volume is large, cost is high, and one-way valve is easily interfered by foreign material and lost efficacy.

Summary of the invention

The object of the invention is to: the shortcoming existed for above-mentioned miscellaneous manual reciprocating pump, propose a kind of compact structure, liquid stream continuously, operate light rotator type manual pump.

In order to achieve the above object, rotator type manual pump of the present invention, comprise the pump housing 1 with suction port and exhaust port, piston 2 that can be reciprocating, the handle 3 reciprocating with making piston 2, its special way is: be fixedly mounted with a cut water cover 4 in the described pump housing 1, this cut water cover 4 arranges the cut water 5 that the pump housing 1 inner chamber is divided into zone of high pressure and low pressure area by a pair; The described pump housing 1 inner chamber is also equipped with coaxial rotor 6, and the radial hole of this rotor 6 is built with piston 2; The projecting shaft of rotor 6 is equipped with handle 3; Article one, have the eccentric shaft 7 of throw of eccentric E with the pump housing 1 inner chamber axis, its one end is packed on pump cover 8, and its other end inserts in the translot of piston 2 waist, hinged with it.

The outer garden of rotor 6 described in technical solution of the present invention can be fixedly mounted with a rotor cover 9, this rotor cover 9 corresponds to rotor 6 radial hole position and is shaped with and that diameter less radial hole 10 coaxial with radial hole, these radial hole 10 both sides are shaped with the narrow groove 11 be communicated with it, form the radial passage of rotor cover 9.

On the cover of cut water described in technical solution of the present invention 4, the width of cut water 5 can equal the width of radial passage on rotor cover 9.

The flywheel 12 of band handle 3 projecting shaft of rotor 6 described in technical solution of the present invention can be equipped with.

The present invention utilizes the motion principle of connecting rod, realizes the suction function of pump, and when operating grip rotary rotor 6, the piston 2 on rotor 6, under the control of eccentric shaft 7, rotates with rotor 6, and the radial hole on an edge rotor 6 is reciprocating; In rotary course, piston 2 sucks liquid from suction chamber, discharges liquid again afterwards, go round and begin again from discharge side; The pump of this positive displacement, hydraulic loss and volumetric loss are all little, and efficiency is very high.

Good effect of the present invention is: one is that rotary operation more adapts to the custom of people than swing type operation, and after particularly having filled flywheel 12, utilize the rotatory inertia of flywheel 12, operate lighter, running speed is faster; Two are pistons 2 is double-action work, and each passes on liquid twice, and running speed is fast, exports liquid stream continuous and stable; Three is eliminate valve arrangement, thus compact structure, volume-diminished, cost reduce.

Embodiment

Fig. 1 is the structural drawing of the embodiment of the present invention., Fig. 2 is the A-A sectional view of Fig. 1, and Fig. 3 is the B-B sectional view of Fig. 1.

Show in figure, rotator type manual pump of the present invention, comprise the pump housing 1 with suction port and exhaust port, suction port connects suction pipe 14, exhaust port connects discharge tube 13, the pump housing 1 inner chamber is fixedly mounted with a cut water cover 4, this cut water cover 4 arranges the cut water 5 that the pump housing 1 inner chamber is divided into zone of high pressure and low pressure area by a pair, and the pump housing 1 inner chamber is also equipped with coaxial rotor 6, and the radial hole of this rotor 6 is built with piston 2; Rocking bar 16 and handle 3 projecting shaft of this rotor 6 be equipped with; Article one, have the eccentric shaft 7 of throw of eccentric E to be packed on pump cover 8 with the pump housing 1 inner chamber axis, its other end inserts in the translot of piston 2 waist, hinged with it.

When operating grip makes rotor turns, the piston 2 on rotor 6, under the control of eccentric shaft 7, rotates with rotor 6, the one epitrochanterian radial hole in edge is reciprocating, in rotary course, sucks liquid from suction chamber, discharge liquid from discharge side again afterwards, go round and begin again.

Rotor projecting shaft is equipped with flywheel 12 to Fig. 4, flywheel 12 is equipped with handle 3, utilizes the rotatory inertia of flywheel, makes operation lighter, quick.

Fig. 5 is the structural drawing that the outer garden of rotor 6 is fixedly mounted with rotor cover 9, and this rotor cover 9 corresponds to rotor 6 radial hole position and is shaped with and that diameter less radial hole 10 coaxial with it, and these radial hole 10 both sides are shaped with the narrow groove 11 be communicated with it, form the radial passage that rotor overlaps 9; On cut water cover 4, the width of cut water 5 equals the width of radial passage on rotor cover 9, and such structure, adds area and the length of sealing, effectively improve sealing effect, thus improves degree of vacuum and the suction capacity of pump.

Fig. 6 is the projection drawing of cut water sealing area, and wherein the narrow groove 11 of radial hole 10 and both sides constitutes the radial passage of rotor cover 9.

After structure of the present invention is revised a little, can be used for manually extracting liquid in bucket, as oil drum etc.
