Abstract
Horizontal internal-connected diaphragm pump belongs to pump class products for agricultural use. The pump body is equipped with an eccentricity drive shaft whose eccentricity cam is equipped with a bearing. A frame structured reciprocating connecting bar is sleeve on the external ring of the bear. The diaphragm assembly of the left and right sides is fixed on the two ends of the frame structured reciprocating connecting bar correspondingly. An outlet one way valve equipped liquid outlet channel and an import one way valve equipped liquid import channel are installed at the upper part inside the pump body. A side cover is fixed at the left and right sides of the pump body, which contains the diaphragm assembly, the outlet one way valve and the import one way valve all together and fixes them on the pump body. This pump structure has the advantages of simple and compact structure, small outside measurement, large liquid flow, small resistance, reliable operation and convenient maintenance.
Description
Technical field
The utility model belongs to the pump series products, relates generally to a kind of diaphragm pump that is used on the agricultural plant protection facility.
Background technique
At present, be configured in the diaphragm pump mostly pressure pump on the agricultural plant protection facility is vertical configuration V-structure, promptly adopt the arrangement that is in the shape of the letter V of two pump heads, drive with two cover crank connecting rods, the pump housing is two body combined types.The diaphragm pump of this structure is in when work, and axial curving and composite deformation take place the barrier film assembly, easily causes the barrier film assembly to fracture and damages, and has reduced working life, has improved operating cost; Simultaneously, vertical V-arrangement diaphragm pump boundary dimension is big, and weight increases, and the split type pump housing is installed again very difficulty, numerous and diverse after maintenance; In addition, the external chennel quarter bend of liquid input, output is too much, and flow resistance is big, has reduced fluid flow, and operating efficiency is lower.
Summary of the invention
The purpose of this utility model is exactly problem and the defective that exists at above-mentioned prior art, design provides logical diaphragm pump in a kind of new structure horizontal, reaches to reduce liquid flowing resistance, increase fluid flow, increase substantially operating efficiency, reduce fault, prolong facility working life, make things convenient for the O﹠M operation, reduce the purpose of pump housing boundary dimension, weight reduction.
Basic design of the present utility model is, on pump housing intermediate portion, be rotatably mounted eccentric drive shaft, bearing is fitted on the eccentric drive shaft eccentric cam position, the reciprocal connecting rod of suit frame type of contact matching on outer race, the barrier film assembly of and arranged on left and right sides is packed on the reciprocal connecting rod of the frame type two end part relatively, and is integral.Be provided with liquid outlet passage and liquid-inlet passage in pump housing upper inner, outlet one-way valve and import one-way valve correspondence respectively are fitted in liquid outlet passage and the left and right port of liquid-inlet passage, liquid outlet and liquid-inlet are arranged on the pump housing upper-end surface, and communicate with liquid outlet passage and liquid-inlet passage respectively.On pump housing and arranged on left and right sides outside, install side cover, this two side cover is positioned at barrier film assembly, outlet one-way valve and the import one-way valve outside of and arranged on left and right sides, barrier film assembly, outlet one-way valve and import one-way valve integral sealing are contained, and extruding is located on the pump housing, the liquid outlet passage and the liquid-inlet passage on its liquid that constitutes each other turnover inner chamber and pump housing top are connected, and so far constitute horizontal interior logical diaphragm pump.
The utility model adopts horizontal interior logical structure, the reciprocal connecting rod driving mode of eccentric drive shaft and frame type, the axial bending and the composite deformation of barrier film assembly have been eliminated, reduced the bent angle quantity of liquid in the pump housing, flowing, have simple and compact for structure, fluid flow is big, flow resistance is little, the operation fault is few, long service life, monnolithic case size are little, in light weight, the characteristics of being convenient to maintaining and use.

Embodiment
Below in conjunction with accompanying drawing the utility model optimum implementation is described in detail.Logical diaphragm pump comprises the pump housing 4 and is configured in barrier film assembly 3 on the pump housing 4 and arranged on left and right sides ends in horizontal, on the pump housing 4 intermediate portions, be rotatably mounted eccentric drive shaft 5, bearing 6 is fitted on the eccentric drive shaft 5 eccentric cam positions, the reciprocal connecting rod 7 of the suit frame type of contact matching on bearing 6 outer shrouds, the barrier film assembly 3 of and arranged on left and right sides is packed on the reciprocal connecting rod of frame type 7 two end part relatively, and is integral.Be provided with liquid outlet passage 10 and liquid-inlet passage 12 in the pump housing 4 upper inner, outlet one-way valve 9 and import one-way valve 13 correspondence respectively are fitted in liquid outlet passage 10 and the liquid-inlet passage 1 left and right port, liquid outlet 8 and liquid-inlet 11 are arranged on the pump housing 4 upper-end surfaces, and communicate with liquid outlet passage 10 and liquid-inlet passage 12 respectively.On the pump housing 4 and arranged on left and right sides outsides, install side cover 1, this two side cover 1 is positioned at barrier film assembly 3, outlet one-way valve 9 and import one-way valve 13 outsides of and arranged on left and right sides, barrier film assembly 3, outlet one-way valve 9 and import one-way valve 13 integral sealings are contained, and extruding location, the liquid outlet passage 10 on its liquid that constitutes each other turnover inner chamber 2 and the pump housing 4 tops and 12 connections of liquid-inlet passage on the pump housing 4.
When operation was used, rotating power passed to the reciprocal connecting rod 7 of frame type through eccentric drive shaft 5, bearing 6, makes the reciprocal connecting rod 7 of frame type do the left and right straight reciprocating motion continuously, and hocket pushing and dragline of the barrier film assembly 3 on a left side and right side moved.When pushing during one side barrier film assembly 3, make liquid in this side liquid turnover inner chamber 2 under positive pressure, outside outlet one-way valve 9, liquid outlet passage 10, liquid outlet 8 excavationg pumps; The synchronous relative side barrier film assembly 3 of dragline, make in this side liquid turnover inner chamber 2 and become negative pressure state, under negative-pressure sucking, liquid is in liquid-inlet 11, liquid-inlet passage 12 and import one-way valve 13 enter liquid turnover inner chamber 2, with liquid in the make-up pump, plant protection operation is finished in alternating movement continuously so repeatedly.Logical diaphragm pump can be serially connected in side by side and form four cylinder diaphragm pumps in the same pump housing in this was horizontal, and the liquid suction amount of its pump can double.
