Abstract

The utility model belongs to the technical field of atomizing pumps, and provides a micro high-pressure oilless plunger atomizing pump. The atomizing pump adopts the structure that a motor, a plunger and a control element are mounted in a housing and a pump head; an eccentric shaft is mounted at the shaft end part of the motor; a bearing and a connecting rod are sleeved on the eccentric shaft; the connecting rod is hinged with the plunger perpendicular to a motor shaft; a water seal, a gasket and an oilless self-lubricating guiding plunger sleeve are sequentially sleeved at the outer end part of the plunger from the outside in; the front end surface of the plunger is communicated with a pumping chamber of the pump head; and the control element adopts the structure that a liquid inlet one-way valve, a liquid outlet one-way valve and a pressure-limiting valve are correspondingly mounted at a liquid inlet, a liquid outlet and a pressure-limiting opening which are communicated with the pumping chamber of the pump head. The atomizing pump has the following advantages: the connection mode that the motor directly drives the plunger through the connecting rod enables the equipment to be miniaturized; and by virtue of the oilless self-lubricating guiding plunger sleeve and the oilless bearing, no lubricant is required in the pump body, so that the installation and maintenance are greatly facilitated, and environmental pollution caused by oil leakage is avoided, thereby satisfying the environment-friendly and low-carbon social requirements.

The purpose of this utility model is achieved in that

High-pressure mini does not have the oil piston atomizer pump, motor, plunger and control original paper are installed in housing and pump head, the shaft end of described motor is equipped with eccentric shaft, be set with bearing and connecting rod on the eccentric shaft, connecting rod is with hinged perpendicular to the plunger of motor shaft, the outer end ecto-entad suit water seal successively of plunger, pad and oil-free self lubrication directional post plug sleeve, the front-end face of plunger is communicated with the pumping chamber of pump head, described control original paper is: correspondence is equipped with into water one-way valve on water intake, water outlet and the pressure limiting mouth that the pumping chamber of pump head is communicated with, goes out water one-way valve and pressure regulator valve.

Above-mentioned connecting rod and plunger hinged place are provided with ceramic needle bearing, and described oil-free self lubrication directional post plug sleeve is an engineering plastics polyimide injection grade compound resin (polyimide YZPI).

Above-mentioned liquid outlet is circumscribed with more than one atomizer nozzle by joint and conduit.

Be circumscribed with pressure gauge in the pumping chamber of above-mentioned pump head.

Above-mentioned bearing and ceramic needle bearing are the selflubricating stuffing box bearing.

Be provided with soft waterproof jacket between the machine operation switch on above-mentioned electric machine casing top and the electric machine casing.

The outstanding compared to existing technology advantage of the utility model is: motor of the present utility model directly drives the connection mode of plunger by connecting rod, the equipment that makes is able to miniaturization, nothing oil by oil-free self lubrication directional post plug sleeve and bearing is provided with, realized the unlubricated oil in the pump housing, made things convenient for greatly and installed and maintenance, avoid the befouling environment that causes because of leakage of oil, met the social demand of environmental protection and low-carbon (LC).

Fig. 2 is that the utility model is not installed motor, conduit, atomizer nozzle and manometric STRUCTURE DECOMPOSITION schematic representation;

Fig. 3 is an agent structure schematic representation of the present utility model.

Embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments, referring to Fig. 1-3: high-pressure mini does not have the oil piston atomizer pump, in housing 5 and pump head 3, motor 1 is installed, plunger 14 and control original paper, the shaft end of described motor 1 is equipped with eccentric shaft 18, be set with bearing 17 and connecting rod 16 on the eccentric shaft 18, connecting rod 16 is with hinged perpendicular to the plunger 14 of motor shaft, the outer end ecto-entad of plunger 14 is set with water seal 11 successively, pad 12 and oil-free self lubrication directional post plug sleeve 13, the front-end face of plunger 14 is communicated with the pumping chamber 19 of pump head 3, and described control original paper is: the liquid entering hole 31 that the pumping chamber 19 of pump head 3 is communicated with, correspondence is equipped with feed liquor one-way valve 8 on liquid outlet 32 and the pressure limiting mouth 33, fluid one-way valve 10 and pressure-limit valve 9.

Above-mentioned connecting rod 16 and plunger 14 are hinged to be that ceramic needle bearing 15 is installed on the axis hole 161 of connecting rod 16 outer ends, bearing pin 141 inner ring and the pin shaft hole of plunger 14 ends by inserting ceramic needle bearing 15 is hinged with connecting rod 16 and plunger 14, and described oil-free self lubrication directional post plug sleeve 13 is engineering plastics polyimide injection grade compound resins (polyimide YZPI).

Above-mentioned liquid outlet 32 is circumscribed with more than one atomizer nozzle 7 by joint and conduit 6, and what of atomizer nozzle 7 can be provided with as required.

Be circumscribed with pressure gauge 2 in the pumping chamber 19 of above-mentioned pump head 3, in order to the pressure in the pumping chamber 19 in the indication pump.

Above-mentioned bearing 17 and ceramic needle bearing 15 are the selflubricating stuffing box bearing.

Be provided with soft waterproof jacket 20 between the machine operation switch on the housing top of above-mentioned motor 1 and the housing of motor 1, soft waterproof jacket 20 usefulness rubber or silica gel are made, and are used to prevent the switch water inlet.

Because ceramic needle bearing 15 and bearing 17 all are oil-less self-lubricating bearings, the lubrication of 13 pairs of plungers 14 of oil-free self lubrication directional post plug sleeve in addition, making does not in use need lubricating oil filling in the chamber at connecting rod 16 places, makes complete machine become the plunger atomizer pump of oil-free lubrication.

During work, motor 1 drives eccentric shaft 18 and makes eccentric rotary, the motion drivening rod 16 of eccentric shaft 18 is also done eccentric motion, because connecting rod 16 is hinged with plunger 14, the eccentric motion of connecting rod 16 promotes plunger 14 and does linear reciprocating motion, the water of the normal pressure power that can introduce by intake pipe 4 and feed liquor one-way valve 8 is left liquid one-way valve 10 through the supercharging pusher and is atomized in the atomizer nozzle 7 through joint and conduit 6 and spray pumping chamber 19 in, when the fluid pressure in the pumping chamber 19 exceeds setting value, pressure-limit valve 9 is opened automatically, highly pressurised liquid in pumping chamber 19 leaks into the low pressure chamber of water inlet, until the pressure that meets setting, owing between connecting rod 16 and eccentric shaft 18, be provided with bearing 17, on plunger 14, be set with oil-free self lubrication directional post plug sleeve 13, significantly reduced the frictional loss of each attachment portion, its fricative heat is also few, therefore in housing 5 inner chambers, can not have oil setting, plunger 14 is provided with water seal 11 and pad 12, can be to sealing mutually in pumping chamber 19 and housing 5 inner chambers, the working principle of plunger 14 in pump head 3, pump head 3, the selflubricating stuffing box bearing, feed liquor one-way valve 8, fluid one-way valve 10, the structure of pressure-limit valve 9 and oil-free self lubrication directional post plug sleeve 13 is prior art, no longer is described further here.The foregoing description only is one of preferred embodiment of the present utility model; be not to limit protection domain of the present utility model according to this; so: all equivalences of doing according to structure of the present utility model, shape, principle change, and all should be covered by within the protection domain of the present utility model.
