Description
【Technical field】
The present invention relates to a kind of inverter compressor motor spiral oil pumping device fixed holding structure of oil suction core pipe, belong to
Frequency-changeable compressor oil pumping device technical field.
【Background technology】
The oil pumping device being arranged in motor is very crucial, and it needs the moving parts such as axle of lubrication mainly for compressor
Hold, piston, linkage connector fuel feeding, the size of oil mass directly affects the abrasion of frequency-changeable compressor, noise, frequency-changeable compressor work
When, take away a part of heat to cool down whole machine by circulating lubricating oil.
The oil pumping device that current compressor is used includes fuel sucking pipe, rotating vane group, and bent axle is fixed in fuel sucking pipe upper end
Main shaft part, rotating vane group is located in fuel sucking pipe.When the compressor is operated, motor belt motor movable vane piece group is rotated and produces centrifugal force, is inhaled
Oil pipe is contained in the lubricating oil in oil sump from the suction of its lower end, realizes that compressor oils.
Frequency-changeable compressor is general in 900-4500rpm, and because the range of speeds is wider, the structure design of existing oil pumping device is bright
Development rings fuel feeding, and pump oil amount changes therewith with the change of rotating speed, and oil suction is not enough under low speed state, and oil ability, when
When rotating speed is less than 1500rpm, oil suction component would become hard to the pump from oil sump and oil, and existing oil pumping device has been difficult to meet the slow-speed of revolution
In the case of each parts of frequency-changeable compressor to the demand that lubricates, so as to influence frequency-changeable compressor job stability and service life,
Also very big restriction is produced to frequency-changeable compressor low speed noise reduction.
Existing spiral oil pumping device includes fuel sucking pipe and oil suction core pipe, and oil suction core pipe is located in fuel sucking pipe.Analysis finds to inhale
Running clearance between oil pipe and oil suction core pipe plays inverse ratio to pump oil amount, when trickle bounce occurs in oil suction core pipe, or even
When being that oil suction core pipe afterbody produces swing, the gap between the fuel sucking pipe and oil suction core pipe of rotation will become uncontrollable, and oil resistance
Power increases, and certainly will influence the stability of pump oil amount under frequency-changeable compressor low speed state.
【The content of the invention】
Protected with the fixed of oil suction core pipe it is an object of the invention to provide a kind of inverter compressor motor spiral oil pumping device
Structure is held, the structure is able to ensure that between fuel sucking pipe and oil suction core pipe that remaining uniform relatively rotates gap so that be equipped with this
The spiral oil pumping device of structure remains to persistently provide stabilization for frequency-changeable compressor in the range of the wide range speed under low speed state
Pump oil amount.
To solve the above problems, the present invention provides following technical scheme：
Inverter compressor motor spiral oil pumping device has spiral recessed with the fixed holding structure of oil suction core pipe, including outer wall
The oil suction core pipe of groove, oil suction core pipe is partly inserted in the fuel sucking pipe of spiral oil pumping device, and the upper end interference of fuel sucking pipe is connected to
The bottom of rotor central siphon, its improvement is：Also include the line card spring across bobbin winder bracket arrangement, the both sides point of line card spring
Other buckle is fixed on the bobbin winder bracket of motor, and line card spring is inserted in oil suction core pipe and fixes oil suction core pipe with tensioner.
Above-mentioned line card spring is by a concave shape section and opening towards two of this concave shape sectionFont section encloses company jointly
Form, wherein, two of line card springFont section connects concave shape section, two respectivelyFont section end edge freedom, and this two
Individual end edge is parallel to each other, twoThe base of font section is snapped on the bobbin winder bracket for being fixed on motor respectively, line card spring its character cut in bas-relief
The depressed part depth of shape section and the oil suction core pipe part in fuel sucking pipe, promote oil suction core pipe to be fixed on concave shape section by tensioner
Depressed part.
The periphery wall of above-mentioned bobbin winder bracket is fixedly provided with two connector assemblies, and two connector assemblies have been respectively fixedly connected with plug, coil spring
Two bases of card snap connection in arranging, the hanging bobbin winder bracket of the line card spring across bobbin winder bracket on the plug respectively.
Due to line card spring hanging bobbin winder bracket arrangement, thus no longer coil windings of interference winding motor, and, no longer shadow
Ring the maintenance replacement operation of coil windings.
Compared with prior art, beneficial effects of the present invention are as follows：
The present invention uses said structure, and the naked section of oil suction core pipe and the lower end of fuel sucking pipe are less than the oil level of oil storage,
Fuel sucking pipe is driven to rotate together when rotor central siphon rotates, it is quiet due to causing under the tensioner effect of the online jump ring of oil suction core pipe
(keeping relatively motionless), then can continue to keep uniform relative rotation gap, from oil sump between fuel sucking pipe and oil suction core pipe
The lubricating oil being inhaled into by the outer wall spiral of oil suction core pipe, and then inwall and oil suction core tube wall along fuel sucking pipe it
Between gap be directed in frequency-changeable compressor, persistently provide stabilization pump oil amount ensure that frequency-changeable compressor in the slow-speed of revolution completely
Lubrication and cooling requirement in the range of wide range speed under state needed for whole machine.
Because the running clearance between fuel sucking pipe and oil suction core pipe is enduringly uniform, the resistance that oiled under low speed state is small,
Pumping ability is strong, and lubrication effect is good, and compressor slow-speed of revolution noise is small, and not by lubricating oil viscosity change under the conditions of low temperature season
Change and influence pumping ability.
