Description
Technical field
The present invention relates to diaphragm pump, particularly relate to spring housing's diaphragm pump, mainly be applicable on the atomizing sprayer.
Background technique
Sprayer is a kind of agricultural plant protection commonly used machinery, is widely used in crops prevention and elimination of disease and pests and health and epidemic prevention etc.Sprayer has manually and electronic two kinds, and power spraye (also being atomizing sprayer), its main structure are compositions such as liquid medicinal case, storage battery, motor, atomizing pump and spray medicine parts.The pump of existing power spraye is to adopt plunger pump (or claiming reciprocating pump) as power, it is big to exist volume mostly, and weight is too heavy, and especially the back-pack electric sprayer has increased the load of human body, and shortcoming such as damage has easily influenced working efficiency again.So minority is used diaphragm pump instead at present, has dwindled volume, has alleviated weight.What use now is the diaphragm type diaphragm pump, and for example Chinese patent numbers 200520101670.9, and name is called " electric diaphragm pump "; The inlet valve of such diaphragm pump and outlet valve are to be matched with the membranelle bar by suction diaphragm and Small diaphragm-piece, at every turn when liquid medicine through the time rely on absorb water diaphragm and Small diaphragm-piece edge to start, but have granule in the water (for example silt etc.) when passing through to absorb water between diaphragm and Small diaphragm-piece and the membranelle bar; In case do not pass by fully; The diaphragm that just in time absorbs water is closed and just is sandwiched in midway, and the suction diaphragm also can produce impression, not only can not wash away when opening next time; On the contrary can be cumulative; Cause the incompetence of suction diaphragm, cause the pressure of pump to descend, forfeiture spraying ability.
Summary of the invention
The objective of the invention is provides a kind of not only volume dexterous, in light weight in order to overcome the shortcoming that prior art exists, and can pass through smoothly for the water small particles, and valve opens and closes fully, reliable operation, the spring diaphragm pump of assurance pump internal pressure.
The technological scheme of spring diaphragm pump of the present invention is: comprise motor, be installed in the eccentric mounting on the motor shaft, the eccentric mounting outer wall is provided with bearing, matches with bearing support in the bearing outside; Be shaped on three stranding sheet fixing columns that rub on the bearing support, be shaped on fixed hole in the fixing column, the edge of fixed hole is provided with seal ring; Bearing support is installed in the big diaphragm seat, is shaped on three circular holes in the big diaphragm seat, and three fixing columns of bearing support pass circular hole; Before big diaphragm seat, big diaphragm is installed, big diaphragm is shaped on attachment hole, in the big diaphragm stranding sequin that rubs is installed; Big diaphragm seat connects pump head, it is characterized in that between big diaphragm seat and the pump head valve being set, and described valve comprises valve seat; Centre is shaped on three water exit valve holes, and outlet valve is installed in the water exit valve hole, and said outlet valve comprises water outlet spool, water outlet spring and spring capping; The water outlet spool matches with water exit valve hole, and the water outlet spool is by the water outlet spring reset, and the water outlet spring is fixed by spring capping; Be shaped on three water inlet valve openings at the valve seat periphery, water inlet is installed into water valve in the valve opening, and said inlet valve comprises into water spool, water inlet spring and fixing press strip; The water inlet spool matches with the water inlet valve opening, and the water inlet spool is by the water inlet spring reset, and the spring of intaking is fixed by fixing press strip.
The invention discloses a kind of spring diaphragm pump, through mounted valve between big diaphragm seat and pump head, valve comprises valve seat; Centre is shaped on three water exit valve holes, and outlet valve is installed in the water exit valve hole, and outlet valve comprises water outlet spool, water outlet spring and spring capping; The valve seat periphery is shaped on three water inlet valve openings, and water inlet is installed into water valve in the valve opening, and inlet valve comprises into water spool, water inlet spring and fixing press strip; Original suction diaphragm and Small diaphragm-piece are started the structure that the structure that reaches water inlet and outlet changes spring into through the edge, when motor shaft drives the diaphragm pump running, diaphragm pump with water in the water intake suction pump of pump head; Water promotes the spool of intaking downwards, and the water inlet spool pushes the water inlet spring downwards, makes whole water inlet spool disengage into water valve opening; Into the water valve opening is unimpeded thereby make, and the granule in the water passes through easily, and the spring of intaking simultaneously receives eccentric mounting, bearing and bearing support offset movement and the vibration that produces; Granule is difficult for being stuck between spring, guarantees that water inlet is unimpeded, when water gets in the cavity between valve seat and the big diaphragm seat; Water upwards promotes the water outlet spool by water exit valve hole; The water outlet spool upwards pushes the water outlet spring, makes whole water outlet spool disengage water exit valve hole, and last water is discharged from the water outlet of pump head.The spring diaphragm pump of this programme, spool cooperates with valve opening through spring, makes spool disengage valve opening fully, makes passing through smoothly of water small particles, reliable operation, the working life of assurance pump internal pressure and diaphragm pump.
Spring diaphragm pump of the present invention, said water inlet spool and water outlet spool comprise the great circle column cap, and the great circle column cap connects the small column handle, and the water-in and water-out spring is positioned on the small column handle, and the great circle column cap matches with the water-in and water-out valve opening.The water-in and water-out spring is installed on the small column handle easy for installation, reliable operation.Said fixedly press strip by screw on valve seat.Screw is reliable.Be shaped on the gland chamber in the said pump head, the top of spring capping is arranged in the gland chamber.The gland chamber is to the spring capping accurate positioning.Described spring capping is shaped on pin and location lug, and described location lug contacts with the water outlet spring, is shaped on the water outlet valve chamber in the described valve seat, and water exit valve hole is shaped on positioning hole between each water exit valve hole in the water outlet valve chamber, and pin is installed in the positioning hole.There has been location lug to contact with the water outlet spring, the accurate positioning of water outlet spring, reliable operation, pin cooperates with positioning hole, and is easy for installation.Be shaped on tenon on the described fixedly press strip, tenon contacts with the water inlet spring.Tenon contacts with the water inlet spring, the accurate positioning of water inlet spring, reliable operation.
