Description

TECHNICAL FIELD

[0001] The utility model relates to O type ring manufacturing technology especially, it relates to compressor O type ring manufacturing tool. BACKGROUND

[0002] Compressor coupling guard shield O type ring is often needed to replace the vulnerable part in the unit maintenance. When O type ring appears the problem of sealing failure and oil leakage, the current treatment method is to replace the whole O type sealing ring. However, this replacement needs to disassemble the coupling, and this operation will bring a series of problems. Maintenance workload and time problem, disassembling the coupling is a complex work, which makes the maintenance workload increase greatly, and further leads to the maintenance time to be significantly prolonged;

[0003] This not only affects the normal operation time of the equipment, but also increases the maintenance cost and labor cost, reduces the equipment maintenance efficiency, improves the convenience of equipment maintenance, shortens the maintenance time, and it is necessary to improve the replacement mode of O type ring. UTILITY MODEL CONTENT

[0004] The utility model aims at providing the O type ring made of fluorine rubber strip, reducing the workload and maintenance time caused by disassembling the coupling when replacing the compressor coupling guard shield O type ring in the traditional way, and another purpose of the utility model is to prevent the slip of the winding rod when clamping, improve the cutting precision, and thus make the O type ring meet the sealing requirements.

[0005] Technical scheme: the compressor O type ring manufacturing tool comprises a hole circular cavity, and is characterized in that: a cutting inclined groove is formed in the outer side wall of the hole circular cavity, and a winding rod is clamped in the hole circular cavity.

[0006] Furthermore, a threaded groove is formed in the upper surface of the winding rod, a threaded column is screw-connected in the threaded groove, a rotating block is fixedly connected to the top end of the threaded column, and a through-type wire clamping port is formed in the outer side wall of the threaded column.

[0007] Furthermore, an antiskid pad is fixedly connected to the outer side wall of the winding rod.

[0008] Furthermore, a fixed ring is fixedly connected to the lower outer side wall of the winding rod.

[0009] Furthermore, the length of the hole circular cavity is 120mm.

[0010] Beneficial effects:

[0011] The compressor coupling guard cover O-shaped ring is a vulnerable part that needs to be replaced during maintenance of the unit, and the replacement of the integral O-shaped sealing ring requires disassembly of the coupling to replace the sealing ring, which is labor-intensive and time-consuming for maintenance. In order to facilitate equipment maintenance and shorten the maintenance time, an O-shaped ring cutting tool is independently designed and manufactured. A special adhesive is used to coat the O-shaped ring on the oblique front surface. The fluororubber strip is coated with a special adhesive on the oblique front surface to form an O-shaped ring.

[0012] In 2021, 4 O-shaped rings were replaced per unit for compressor couplings, and 4 O-shaped rings were replaced per unit (imported O-shaped ring single price 480 yuan per unit). The actual operation of the compressor is 8K hours, and the sealing is verified to be normal during disassembly and inspection, meeting the use requirements. Directly save 0.768 million yuan.
