Description
Technical Field
The utility model relates to a compressor technical field specifically is a labyrinth compressor is with experimental piston structure.
Background
The labyrinth compressor is a novel compressor which adopts non-contact labyrinth sealing technology between a piston and a cylinder wall and between a piston rod and a filler. The labyrinth piston compressor has non-contact sealing structure, piston and stuffing sealed via labyrinth, and air sucking, compressing and exhausting work circulation. Because of the labyrinth non-contact sealing, in actual use, trace gas is inevitable to pass through a gap between the piston and the cylinder wall, and the labyrinth throttling test in the reciprocating motion process is necessary.
Disclosure of Invention
Sensor installation difficulty and the high problem of piston replacement cost when solving current labyrinth compressor test, the utility model provides a labyrinth compressor is with experimental piston structure, it can solve sensor installation difficulty to effectively reduce the cost of labyrinth compressor test.
The technical scheme is as follows: the piston structure for the labyrinth compressor comprises a piston body and is characterized in that a shell is fixed on the outer peripheral surface of the piston body through screws, labyrinth tooth shapes are formed in the outer peripheral surface of the shell, and pressure sensor mounting holes are formed in the side wall of the piston body and the side wall of the shell.
The piston is further characterized in that the piston body comprises a middle shaft sleeve, the end part of the middle shaft sleeve is connected with the middle part of the disc body, the outer peripheral surface of the disc body is connected with a ring body, a dead zone is formed between the middle shaft sleeve and the ring body and is provided with at least two connecting blocks, and the middle shaft sleeve, the disc body, the ring body and the connecting blocks are of an integrated structure;
the improved screwdriver is characterized in that the disc body is provided with steps, a circle of threaded counter bores are formed in the step surface, the shell is a ring-shaped piece with a convex ring, and the convex ring is provided with screws matched with the threaded counter bores.
Adopt the utility model discloses afterwards, change the piston into split type structure, the shell can be changed, only needs piston body of processing, reprocesses the demand that the profile of tooth shell of a plurality of different mazes can satisfy different piston bodies, the effectual cost that reduces the labyrinth compressor test to the pressure sensor mounting hole can be convenient installation pressure sensor.

Detailed Description
Referring to fig. 1 and 2, the piston structure for the labyrinth compressor comprises a piston body 1, wherein a shell 2 is fixed on the outer peripheral surface of the piston body 1 through a screw 3, and labyrinth tooth shapes are formed on the outer peripheral surface of the shell 2.
The piston body 1 comprises a middle shaft sleeve 1-1, a key groove is formed in the middle shaft sleeve 1-1, the end of the middle shaft sleeve 1-1 is connected with the middle of a disc body 1-2, the peripheral surface of the disc body 1-2 is connected with a ring body 1-3, a dead zone is formed between the middle shaft sleeve 1-1 and the ring body 1-3, three connecting blocks 1-4 are arranged, the middle shaft sleeve 1-1, the disc body 1-2, the ring body 1-3 and the connecting blocks 1-4 are of an integrated structure, weight reduction can be effectively achieved in the dead zone, and reliability of the piston body 1 is guaranteed through the connecting blocks 1-4.
The disc body 1-2 is provided with steps, the step surface is provided with a circle of threaded counter bores, the shell 2 is a ring-shaped element with an inner convex ring, and the convex ring is provided with screws 3 matched with the threaded counter bores, so that the shell 2 can be stably and reliably fixed on the piston body 1.
Pressure sensor mounting hole 4 has been seted up on piston body 1 and the 2 lateral walls of shell, can install pressure sensor in the downthehole, the piston is installed and is had labyrinth profile of tooth piston intracavity equally at the inner wall, labyrinth compressor during operation, the gaseous trend that leaks to the non-compression side of piston compression side, leak when the clearance of a small amount of compressed gas to piston and piston intracavity wall, every labyrinth tooth chamber all can form a throttle chamber, gaseous progressively attenuates through a plurality of throttle chamber pressures, until the pressure of non-compression side is equal, after having installed pressure sensor on the piston, can detect the pressure value in labyrinth throttle chamber, test the effect of labyrinth throttle.
