Abstract
Disclosed is a power atomizing sprayer vortex pump which comprises a gasoline engine. A rotor is mounted in the gasoline engine connected with a pump body, and a water inlet and a water outlet are arranged on the pump body provided with a pump cover. The vortex pump is characterized in that the rotor of the gasoline engine is connected with a flange plate, a rotary shaft is disposed on the flange plate, a mechanical sealing device is arranged between the rotary shaft and the pump body, an impeller is mounted on an end portion of the rotary shaft, intersected blades are arranged on the edges of two sides of the impeller, round runners are arranged on the pump body and the pump cover which correspond to the blades, and the water inlet and the water outlet are communicated with the round runners and separated via a baffle tongue. When the impeller rotates, liquid in the blades of the impeller and the round runners moves along a circumferential direction, thereby producing centrifugal force; the circumferential speed of the liquid in the impeller is larger than that of the liquid in the round runners, thereby forming annular flow; and the liquid employing longitudinal vortex which is perpendicular to a shaft surface and directs to the round runners passes through the impeller repeatedly in the round runners, thereby obtaining higher energy, greatly improving delivery lift and achieving high pressure and good atomization.
Description
Technical field
The utility model relates to peripheral pump, particularly relates to a kind of peripheral pump that matches with the backpack motor atomizer, belongs to the agricultural plant protection mechanical field.
Background technique
Motor atomizer belongs to a kind of agricultural plant protection machinery commonly used, can be used for the control of diseases and pests of agronomic crop, also can be used for Antiepidemic sterilizing on health.Have and generally use plunger pump as the backpack motor atomizer of power by petrol engine, mainly drive the driven disc of plunger pump by the clutch of petrol engine, driving eccentric wheel after reduction gears mechanism slows down makes two plungers do horizontal to-and-fro motion, the shortcoming of its existence is: one, transmission part is many, complex structure, big, the easily leakage of vibrations, fluid pulse is obvious, and spray boom has the sense of trembling during operation; Two, adopt the clutch transmission, the rotating speed of petrol engine must reach 4000 rev/mins of ability and start plunger pump, even only need the atomizing sprayer operating on low voltage, petrol engine also must high rotation speed operation reach nominal power or peak output, wastes fuel oil, aggravation wearing and tearing like this, has improved cost; Three, use clutch, the friction plate of clutch is an easily damaged parts, wearing and tearing easily, and working life is short, need often change, repair trouble.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of prior art, to provide a kind of employing petrol engine rotor to be connected with pump shaft is rigid, impeller work balance, current do not have pulse, shake little, the motor atomizer peripheral pump that noise is low.
The technological scheme of the utility model motor atomizer peripheral pump is: comprise petrol engine, rotor is installed in the petrol engine, petrol engine connects the pump housing, be shaped on water intake and water outlet on the pump housing, the pump housing has pump cover, it is characterized in that described petrol engine rotor mounting flange, be shaped on rotating shaft on the flange plate, between the rotating shaft and the pump housing mechanical seal device is arranged, impeller is installed in end in rotating shaft, and the edge of described impeller both sides is shaped on the blade to mistake, is shaped on circular flow channel on the pump housing corresponding with blade and the pump cover, water intake and water outlet are communicated with circular flow channel, and are separated by cut water.
Motor atomizer peripheral pump of the present utility model, its described rotor mounting flange, be shaped on rotating shaft on the flange plate, promptly adopt the petrol engine rotor to be connected with the rotating shaft of pump is rigid, petrol engine one starts, pump is just started working, can satisfy the spraying requirement under the different pressures like this, if customer requirements is the spraying of low-pressure, petrol engine can be operated in the slow-speed of revolution, save oil consumption, reduce cost.Mechanical seal device (patent is arranged in addition) is arranged between the rotating shaft and the pump housing, guarantee sealing, prevent that soup from entering into petrol engine from the gap location leakage of the rotating shaft and the pump housing.Impeller is installed in the end of rotating shaft, and the edge of described impeller both sides is shaped on the blade to mistake, makes impeller balance when the high speed rotating good to the blade of mistake, has avoided the generation of resonance.Make impeller simultaneously when rotating, cause the motion of making circumferencial direction in the impeller blade with the interior liquid of circular flow channel, thereby produced centrifugal force, the peripheral velocity of liquid is greater than the peripheral velocity of liquid in the circular flow channel in the impeller, so formed annularly flow, liquid relies on the vertical vortex perpendicular to axial plane sensing circular flow channel repeatedly to pass through impeller in circular flow channel, thereby has obtained higher energy, improved lift greatly, the pressure high atomization is good.
Motor atomizer peripheral pump of the present utility model, be shaped on backwater hole on its described water outlet, prior art is installed a back-water valve (BWV) at this position, makes soup be back to medicine-chest when shower nozzle takes place to stop up, the back-water valve (BWV) parts are many, trouble is installed, and damages easily, directly on water outlet, be shaped on backwater hole now, the aperture of backwater hole is very little, under normal circumstances soup does not reflux, and is simple in structure, easy to manufacture.Be shaped on the balance water hole on its described impeller, because the error of accuracy of manufacturing and assembling, cause the gap between possibility impeller and the pump housing and impeller and pump cover different, be that the impeller both sides produce pressure difference, cause impeller when high speed rotating, can produce vibration, the balance water hole is arranged, the current that impact impeller are passed through through the balance water hole, play stabilization, thereby also reduced the friction of impeller the pump housing or pump cover.Be shaped on fixed hole in its described flange plate, fixed hole connects rotor through set screw, and is easy to connect, and it is firm to install.
