Abstract
The utility model relates to a dual-cylinder reciprocating piston compressor, which comprises a crank box, a crank, a slider, a piston arm, a piston head and cylinders, wherein the slider, the piston arm, the piston head and the cylinders are symmetrically arranged on both sides relative to the crank as the center to form the dual-cylinder reciprocating piston compressor. Compared with the prior single-cylinder reciprocating piston compressor, the dual-cylinder reciprocating piston compressor has dual-cylinder design and can improve the production and processing efficiency. In addition, an original sealing element of the crank box can be obviated due to the absence of a fluid for balancing the pressure, so that the crank box changes from the sealed type structure to the open structure, thereby simplifying the crank box structure and prolonging the service life of ear part. In addition, the piston head is fixedly connected with the piston arm to obviate the need of a joint bearing, the slider keeps contact with the piston arm through a rolling pair instead of a planar pair, thereby simplifying the structure of the piston compressor, improving the strength and the accuracy of parts, and prolonging the service life of the compressor.
Description
Technical field
The utility model relates to a kind of reciprocating-piston compressor.
Background technique
At present, in refrigerant recovering, filling product manufacturing process, extensively adopt high pressure single cylinder reciprocating-piston compressor.
Injection pressure fluid in the crankcase of high pressure single cylinder reciprocating-piston compressor makes piston head produce back pressure and comes equalizing piston head positive pressure, guarantees that motor starts under low moment of torsion smoothly.But there are following many defectives in existing high pressure single cylinder reciprocating-piston compressor.At first, motor rotates a circle, a compressor work done once, its work efficiency is low; Secondly, can suffer erosion in the fluid, greatly shorten the working life of component because parts such as bearing are immersed in; Once more, adopt joint shaft bearing to be connected between piston head and the piston arm, along with lining ground weares and teares fast, the cylinder allowance increases rapidly, and the compression ratio reduction causes compressor not reach pressure maximum; At last, compressor has from cleaning function, after processes such as recovery, filling finish, remove the residual fluid in the crankcase, and in order to prevent the leakage of fluid in operating process such as recovery, filling, crankcase must be installed seal arrangement.
Summary of the invention
At above-mentioned technical problem, the utility model discloses a kind of reciprocating-piston compressor that the twin-tub structure is set.
The technical solution of the utility model is as follows: the twin-cylinder reciprocating piston compressor, comprise crankcase, bent axle, slide block, piston arm, piston head and cylinder, with the bent axle is the center, and bilateral symmetry is provided with slide block, piston arm, piston head and cylinder, constitutes the twin-cylinder reciprocating piston compressor.
Described twin-cylinder reciprocating piston compressor, two side slides form an integral body or adopt locating stud to link to each other between the two.
Contact by rolling pair or bearing between described twin-cylinder reciprocating piston compressor, slide block and bent axle.
Contact by rolling pair or support roller between described twin-cylinder reciprocating piston compressor, slide block and piston arm.
Adopt between described twin-cylinder reciprocating piston compressor, piston arm and piston head and be threaded.
Described twin-cylinder reciprocating piston compressor adopts screw thread to link to each other between the piston arm of both sides.
Described twin-cylinder reciprocating piston compressor, removable being fixedly linked between bent axle and the drive motor axle, crankshaft end is by bearings.
Compare with existing single cylinder reciprocating-piston compressor, piston compressor of the present utility model adopts the twin-tub design, improves the efficient of its production and processing.In addition, come balance pressure because of need not fluid, can remove the Sealing of the original setting of crankcase, crankcase is changed into open by sealed type, both simplified the structure of crankcase, has prolonged the working life of each component again.Moreover, removed joint shaft bearing between piston head and piston arm and fixedlyed connected, adopt the rolling pair contact between slide block and the piston arm, slide block changes the rolling pair contact into by planar pair flat pair, simplify the structure of piston compressor, improved intensity and precision between component, prolonged the working life of compressor.

Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is elaborated.
Embodiment one: as shown in Figure 1, 2, the twin-cylinder reciprocating piston compressor comprises crankcase 11, bent axle 5, slide block 6, piston arm 3, piston head 2 and cylinder 1, and bent axle 5, slide block 6, piston arm 3 are in the crankcase 11.
The two ends of bent axle 5 are supported by crankshaft bearing 15, and 13 of bent axle 5 and motor shafts are fixedly linked, but both are detachable, and the two ends of motor 12 are supported by motor bearings 14.With bent axle 5 is the center, and bilateral symmetry is provided with slide block 6, piston arm 3, piston head 2 and cylinder 1.6 of bent axle 5 and slide blocks contact by rolling pair 4, and 3 of slide block 6 and piston arms contact by rolling pair 7.6 of two side slides pass through locating stud 8 location.Fixing between the piston arm 3 of both sides by socket head screw 9, link to each other by interior hexagonal double-ended bolt 10 between piston arm 3 and the piston head 2, detachable between the two.Respectively connect cylinder 1 outside the two side of crankcase 11, piston head 2 passes the sidewall of crankcase 11 and stretches in the cylinder 1.Above-mentioned constituted have twin-tub, the reciprocating-piston compressor of rolling pair slide block structure.
Starting electrical machinery, will rotatablely move is transferred to bent axle, and bent axle drives slide block movement, and slide block moves up and down with respect to piston arm, thereby makes piston arm make move left and right together with piston head, the piston acting.
Reciprocating-piston compressor of the present utility model adopts the twin-tub design, the piston head pressure of both sides keeps balance, guarantee that motor starts smoothly under low moment of torsion, and need not produce the piston back pressure by perfusion of fluid, thereby bearing is not subjected to fluid erosion, under normal lubricating status, guarantee the working life of bearing; Save the parts that have from cleaning function, improved the ease for operation of compressor.The motor of twin-cylinder reciprocating piston compressor rotates a circle, and piston just does work twice, and improving overall efficiency can reach more than the twice.Because no fluid in the crankcase then saves Sealing, simplifies the structure, and makes the installation, maintenance of component easier.Piston arm is fixedlyed connected with piston head, has saved joint shaft bearing, has overcome the liner wear problem of joint shaft bearing, makes allowance, compression ratio, the pressure of cylinder constant, guarantees the stability of compressor operating.
Embodiment two: shown in Fig. 3,4, an end of bent axle 5 is supported by crankshaft bearing 15, and 6 of bent axle 5 and slide blocks contact by bearing 4, and 3 of slide block 6 and piston arms contact by support roller 7.Two side slides 6 form an integral body.
Other content of present embodiment is identical with embodiment one.
