Description

Technical Field

[0001] This utility model relates to the field of compressor technology, and in particular to a novel single-screw water-lubricated compressor. Background Technology

[0002] A single-screw compressor is a positive displacement compressor consisting of a cylindrical screw and two symmetrically arranged planar star wheels forming a meshing pair, housed within a casing. It is widely used in food freezing, refrigeration, ice making, residential and commercial air conditioning, and industrial refrigeration.

[0003] In the petrochemical industry, the compressed media inside compressors are mostly flammable, explosive, or even highly toxic substances, which places high demands on the compressor's sealing performance. Currently, compressors mainly use mechanical seals or dry gas seals, which are not very reliable and are expensive. In addition, dry gas seals or mechanical seals are prone to leakage and contamination of the compressed media, making them unsuitable for applications with high operating requirements and thus reducing the practicality of the equipment. Utility Model Content

[0006] By adopting the above technical solution, water is injected into the main shaft system through the water injection hole, so that the single screw compressor uses water as the lubrication and working medium.

[0007] In a preferred embodiment, the disassembly assembly includes mounting blocks fixedly connected to both sides of the dustproof sealing plug, each mounting block having a locking bolt inside, and the mounting block being connected to the pressure cap via the locking bolts.

[0008] By adopting the above technical solution and setting the locking bolt, the mounting block can be fixedly installed on the pressure cover, thereby achieving the purpose of fixing the dustproof sealing plug.

[0009] In a preferred embodiment, the inner wall of the stationary ring abuts against the outer side of the main shaft system, and the outer side of the main shaft system abuts against the inner wall of the moving ring.

[0010] By adopting the above technical solution and through the abutment setting, the connection between the main shaft system, the rotating ring and the stationary ring can be strengthened, and the layout is reasonable.

[0011] In a preferred embodiment, a spindle bearing seat is fixedly installed inside the housing and on one side of the pressure cover, and the spindle bearing seat is in a fitted state with the side of the stationary ring that is close to it.

[0012] By adopting the above technical solution, the main spindle system can be positioned and installed through the function of the main spindle bearing housing.

[0013] In a preferred embodiment, a top cover is fixedly installed inside the housing. The top cover is located at the end of the main shaft system away from the pressure cover, and the top cover abuts against the main shaft bearing seat.

[0014] By adopting the above technical solution, the top of the shell can be sealed by the top cover, improving the ease of assembly.

[0018] 1. In this utility model, after the single screw compressor is assembled, the operator can inject water into the main shaft system through the water injection hole, so that the single screw compressor uses water as a lubricating and working medium. This not only saves a lot of oil, but also avoids the environmental pollution caused by traditional bearings that use oil as a lubricating medium. At the same time, water has the characteristics of being pollution-free, widely available, highly safe and inexpensive, thus meeting the needs of high-demand operating conditions.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] Reference Figure 1-3 A novel single-screw water-lubricated compressor includes a housing 1. A main shaft system 3 is installed inside the housing 1. Stationary rings 8 are fixedly installed inside the housing 1 on both sides of the main shaft system 3. A rotating ring 5 is fixedly installed inside the housing 1 on one side of the stationary rings 8. A pressure cover 6 is installed inside the housing 1 on one side of the main shaft system 3. A disassembly assembly is provided inside the pressure cover 6. A water injection hole 13 is opened inside the pressure cover 6. A dustproof sealing plug 9 is inserted into the water injection hole 13. A sealing ring 12 is fixedly connected to the side of the dustproof sealing plug 9 near the water injection hole 13. After the single-screw compressor is assembled, workers can inject water into the main shaft system 3 through the water injection hole 13, allowing the single-screw compressor to use water as a lubricating and working medium. This not only saves a significant amount of oil but also avoids the environmental pollution caused by traditional bearings that use oil as a lubricating medium. Furthermore, water is pollution-free, widely available, highly safe, and inexpensive, thus meeting the needs of applications with high operating requirements.

[0026] Specifically, the disassembly assembly includes mounting blocks 11 fixedly connected to both sides of the dustproof sealing plug 9. Each mounting block 11 has a locking bolt 10 inside. The mounting blocks 11 are connected to the pressure cover 6 through the locking bolts 10. By setting the locking bolts 10, the mounting blocks 11 can be fixedly installed on the pressure cover 6, thereby achieving the purpose of fixing the dustproof sealing plug 9. This can seal the inner cavity of the housing 1 and prevent water leakage. The inner wall of the stationary ring 8 abuts against the outer side of the main shaft system 3, and the outer side of the main shaft system 3 abuts against the inner wall of the rotating ring 5. Through the abutment setting, the connection tightness between the main shaft system 3, the rotating ring 5 and the stationary ring 8 can be strengthened. The layout is reasonable. Inside the housing 1 and on one side of the pressure cover 6, a main shaft bearing seat 7 is fixedly installed. The side of the main shaft bearing seat 7 that is close to the stationary ring 8 is in a close fit. Through the function of the main shaft bearing seat 7, the main shaft system 3 can be positioned and installed, and it plays an important supporting role.

[0027] Specifically, a top cover 4 is fixedly installed inside the housing 1. The top cover 4 is located at the end of the main shaft system 3 away from the pressure cover 6. The top cover 4 can seal the top of the housing 1, improving the ease of assembly. The top cover 4 abuts against the main shaft bearing seat 7. The outer side of the sealing ring 12 fits against the inner wall of the water injection hole 13. An external bearing box 2 is fixedly installed on the outer side of the housing 1. The sealing ring 12 can enhance the sealing performance of the dustproof sealing plug 9 and prevent water medium from leaking through the gap between the water injection hole 13 and the dustproof sealing plug 9.

[0028] Working principle: First, after the single-screw compressor is assembled, the operator can inject water into the main shaft system 3 through the water injection hole 13, so that the single-screw compressor uses water as a lubricating and working medium. This not only saves a lot of oil, but also avoids the environmental pollution caused by traditional bearings that use oil as a lubricating medium. Then, the mounting block 11 can be fixed on the pressure cover 6 using the locking bolt 10, thereby achieving the purpose of fixing the dustproof sealing plug 9. This can seal the inner cavity of the housing 1, and the sealing performance of the dustproof sealing plug 9 can be further enhanced by the setting of the sealing ring 12, preventing water from leaking through the gap between the water injection hole 13 and the dustproof sealing plug 9.
