Description

Technical Field

[0001] This utility model belongs to the field of oxygen compressor technology, and in particular relates to a screw-type oil-free oxygen compressor. Background Technology

[0002] An oxygen compressor is a compressor used to pressurize and deliver oxygen. Oxygen is a highly reactive oxidizer, easily causing combustion and explosion. When designing and using oxygen compressors, the following should be noted: 1. Compressing gas components must not come into contact with oil. Cylinders should be lubricated with water and glycerin, or oil-free lubrication, instead of oil. During maintenance, prevent oil contamination; clean and dry with solvent before assembly. 2. Due to the high humidity during water lubrication and the increased temperature during compression, and the corrosive nature of oxygen from the wet gas holder, materials in contact with oxygen must be corrosion-resistant and possess good thermal and electrical conductivity. Cylinders are generally made of phosphor bronze, pistons of aluminum alloy, and intercoolers of copper or stainless steel tubing. Utility Model Content

[0003] The purpose of this invention is to provide a screw-type oil-free oxygen compressor, which solves the existing problems through the design of the screw head.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] Furthermore, a switch is installed on the top of the lubricating oil pump, and the control terminal of the switch is electrically connected to the PLC control system, which in turn is electrically connected to the motor. This design allows operators to control the opening and closing of the lubricating oil pump via the PLC control system.

[0007] Furthermore, one end of the exhaust pipe extends through the side of the gearbox and housing. The exhaust pipe is designed primarily to release compressed oxygen.

[0008] Furthermore, the screw compressor head is configured with two sections, namely a female screw and a male screw, wherein one end of the female screw is close to the compressor body, and one end of the male screw is close to the output shaft of the motor.

[0009] Furthermore, the surfaces of the screw compressor head and the compressor body are coated with a high-temperature resistant coating. The main function of the high-temperature resistant coating is to provide high-temperature protection for the screw compressor head and the compressor body.

[0010] Furthermore, an air intake pipe extends through the top of the housing, with one end of the air intake pipe fixedly connected to the top of the compressor body. The function of the air intake pipe is to allow oxygen to enter the top of the compressor body for compression.

[0011] This utility model has the following beneficial effects:

[0012] 1. This utility model solves the problem of frequent maintenance during use by using components such as screw head and gearbox in cooperation, thereby reducing maintenance costs, reducing equipment noise and reducing energy consumption.

[0023] Please see Figure 1-4 This utility model is a screw-type oil-free oxygen compressor, including a housing 1. A PLC control system 2 is provided on the side of the housing 1. A motor 3 is fixedly connected inside the housing 1. A screw head 4 is fixedly connected to the output shaft of the motor 3. One end of the screw head 4 passes through the compressor body 5. A gearbox 6 is fixedly connected inside the compressor body 5. A lubrication chamber 7 is fixedly connected to the top of the gearbox 6. A lubricating oil pump 8 is fixedly connected to one end of the lubrication chamber 7. One end of the gearbox 6 is penetrated by one end of the screw head 4. A separation chamber 9 is provided at the bottom of the gearbox 6. A leakage hole is provided inside the separation chamber 9. An exhaust pipe 10 is fixedly connected to one end of the separation chamber 9.

[0024] A switch 11 is installed on the top of the lubricating oil pump 8. The control terminal of the switch 11 is electrically connected to the PLC control system 2, and the PLC control system 2 is electrically connected to the motor 3. This design allows the operator to control the opening and closing of the lubricating oil pump 8 through the PLC control system 2.

[0025] One end of the exhaust pipe 10 passes through the side of the gearbox 6 and the housing 1. The exhaust pipe 10 is designed primarily to release compressed oxygen.

[0026] The screw head 4 is configured in two sections, namely a female screw and a male screw. One end of the female screw is close to the compressor body 5, and the other end of the male screw is close to the output shaft of the motor 3.

[0027] The screw compressor head 4 and the compressor body 5 are coated with a high-temperature resistant coating. The main function of the high-temperature resistant coating is to provide high-temperature protection for the screw compressor head 4 and the compressor body 5.

[0028] An air intake pipe 12 runs through the top of the housing 1, and one end of the air intake pipe 12 is fixedly connected to the top of the compressor body 5. The function of the air intake pipe 12 is to allow oxygen to enter the top of the compressor body 5 for compression.

[0029] One specific application of this embodiment is as follows: Oxygen first enters the compressor body 5 through the intake pipe 12, and then enters the oil-free compressor head driven by the motor 3. The compressor head gas chamber is completely oil-free. The screw head 4 and the housing inside the compressor body 5 are coated with a high-temperature resistant coating (Teflon) to reduce deformation during high-temperature compression. After the oxygen is compressed to the set pressure by the screw head 4, it is discharged. The screw rotor bearing and gearbox 6 are separated from the compression chamber by a mechanical seal, and a leakage hole is set in the separation chamber 9. In this way, if the seal fails, the lubricating oil will not leak into the gas chamber, ensuring that the gas is oil-free and safe.
