Description
Technical field
The utility model relates to a kind of rolling piston type refrigerating compressor of low noise vibrating, belongs to refrigeration compressor manufacturing technology field.
Background technique
Employed rolling piston type refrigerating compressor on the market is set to hyperbaric chamber in the housing at present, adopts rotary structure.Be connected on the compressor housing because the pump housing of rolling piston compressor and motor are the modes by interference or welding, no damping, buffering mechanism makes that compressor vibration in the running is bigger.In addition, owing to be set to hyperbaric chamber in the housing, the refrigerator oil of compressor is easy to be taken out of with refrigeration agent, causes the spray volume of refrigerator oil more; The noise of compressor operation is also bigger simultaneously.Therefore, the present more use of the compressor of this class formation is on the outdoor machine of air-conditioning and commercial refrigeration utensil.
Summary of the invention
The purpose of this utility model is: provide in a kind of housing and be set to low-pressure cavity, adopt the rolling-piston-type structure, be connected with housing by inside exhaust pipe spare; Adopt the rolling piston type refrigerating compressor of the low noise vibrating of damping spring support between the pump housing and the housing.
The utility model is to realize above-mentioned purpose by the following technical solutions:
A kind of rolling piston type refrigerating compressor of low noise vibrating, it is by lower shell body, inside exhaust pipe, supported spring, cylinder head, lower bearing, cylinder body, bent axle, rolling piston, slide block, extension spring, upper bearing (metal), motor and upper shell constitute, upper shell and lower shell body are by being welded to connect, be equipped with by cylinder head in upper shell and the lower shell body, cylinder body, bent axle, rolling piston, slide block, the pump housing that extension spring and motor constitute, the bent axle of the pump housing is fixedly mounted on the center of upper shell and lower shell body by upper bearing (metal) and lower bearing, and it is characterized in that: the described pump housing is fixed on the bottom of lower shell body by supported spring; Be welded with inside exhaust pipe on the cylinder head of pump housing bottom, the other end of inside exhaust pipe is connected with upper shell and runs through.
The rolling piston type refrigerating compressor of this low noise vibrating compared with prior art has following beneficial effect:
1, the pump housing adopts damping spring to support, and has the little characteristics of vibration.
2, be set to low-pressure cavity in the housing, have the little characteristics of oil spout.
3, be set to low-pressure cavity in the housing, the pump housing has the little characteristics of noise by the inside exhaust pipe perforation that is connected with housing.
Description of drawings:
Accompanying drawing is a kind of sectional structure schematic representation of rolling piston type refrigerating compressor of low noise vibrating.
Among the figure: 1, lower shell body, 2, inside exhaust pipe, 3, supported spring, 4, cylinder head, 5, lower bearing, 6, cylinder body, 7, bent axle, 8, rolling piston, 9, slide block, 10, extension spring, 11, upper bearing (metal), 12, motor, 13, upper shell, 14, the sealed wiring post, 15, refrigerator oil, 16, outlet valve.
Embodiment:
The rolling piston type refrigerating compressor of this low noise vibrating is made of lower shell body 1, inside exhaust pipe 2, supported spring 3, cylinder head 4, lower bearing 5, cylinder body 6, bent axle 7, rolling piston 8, slide block 9, extension spring 10, upper bearing (metal) 11, motor 12, upper shell 13 and outlet valve 16.Lower shell body 1 and upper shell 13 are by being welded to connect, the pump housing that is made of cylinder head 4, cylinder body 6, bent axle 7, rolling piston 8, slide block 9, extension spring 10 and motor 12 is installed in lower shell body 1 and the upper shell 13, the bent axle 7 of the described pump housing is fixedly mounted on the center of lower shell body 1 and upper shell 13 by upper bearing (metal) 11 and lower bearing 5, by bolt 3 supported springs 3 are installed on the lower bearing 5, the other end of 3 supported springs 3 is installed in the inner face bottom of lower shell body 1, the whole pump housing is supported on the bottom of lower shell body 1 by 3 supported springs 3.The middle part of described bent axle 7 is equipped with rolling piston 8, and the outside of rolling piston 8 is equipped with cylinder body 6, has chute on the cylinder body 6, is equipped with slide block 9 in the chute, and by extension spring 10 slide block 9 and rolling piston 8 is meshed all the time.Described motor 12 places on the upper bearing (metal) 11 on cylinder body 6 tops, and is connected with sealed wiring post 14 on the upper shell 13; On the described upper bearing (metal) 11 outlet valve 16 is installed, is welded with inside exhaust pipe 2 on the cylinder head 4 of cylinder body 6 bottoms, the other end of inside exhaust pipe 2 is connected with upper shell 13 and runs through.
The working principle of the rolling piston type refrigerating compressor of this low noise vibrating is as follows:
Behind the power connection, motor 12 drives bent axle 7 and rotates, and bent axle 7 drives rolling piston 8 and rotates thereupon, and is divided into air-breathing cylinder body 6 and exhaust cavity by the slide block 9 with rolling piston 8 engagements.Compressor air suction and compression are carried out simultaneously, and the outlet valve 16 when exhaust pressure rises to certain pressure on the upper bearing (metal) 11 is opened.External by the inside exhaust pipe 2 discharge compression cases of welding on the cylinder head 4 through the pressurized gas after the overcompression.
The rolling piston type refrigerating compressor of this low noise vibrating is owing to adopt the mode of structure of rolling piston 8, and the suction air cavity on the cylinder body 6 is worked simultaneously, air-breathing, compression that cylinder body 6 carries out simultaneously.The whole pump housing is supported on the lower shell body 1 by supported spring 3, makes the pump housing obtain cushioning effect; Friction pair between upper bearing (metal) 11, lower bearing 5 and the rolling piston 8 after refrigerator oil 15 is played its pump by bent axle 7 on the lubricated bent axle 7.
The above is the embodiment of this model utility, above-mentioned not illustrating is construed as limiting flesh and blood of the present utility model, the person of an ordinary skill in the technical field can make an amendment or is out of shape after having read this specification above-mentioned embodiment, and does not deviate from essence of the present utility model and scope.
