Description

Technical Field

[0001] The utility model relates to the technical field of seal positioners, in particular to a dry gas seal replacement positioner for a MAN compressor. Background Art

[0002] The disassembly and installation of dry gas seals is a key process in unit maintenance. The key to the disassembly and installation of dry gas seals lies in: axial and radial positioning of the rotor, strict disassembly and installation data, complete special disassembly and installation tools, and a clean maintenance environment;

[0003] When repairing the compressor gas seal, the sleeve cannot be installed when installing the sleeve. The drive pin of the sleeve is not aligned with the pin hole of the dry gas seal drive sleeve, and the sleeve cannot be installed, which affects the maintenance efficiency. Utility Model Content

[0004] Purpose of the utility model: The purpose of the utility model is to provide a solution to the problem that the shaft sleeve cannot be installed when the compressor air seal is being repaired.

[0005] Technical solution: A MAN compressor dry gas seal replacement positioner comprises a cross bar, a semicircular block is fixedly connected to the lower surface of the cross bar, and a through-type card slot is integrally formed below the front surface of the semicircular block.

[0006] Furthermore, the left side and the right side of the lower surface of the crossbar are fixedly connected with support blocks, and the lower surface of the support block is fixedly connected with a rubber pad.

[0007] Furthermore, the cross bar, the semicircular block and the two support blocks are all made of stainless steel.

[0008] Furthermore, the radius of the slot is 18MM.

[0009] Furthermore, the length of the cross bar is 550MM.

[0010] Beneficial effects:

[0011] By cooperating the slots on the outer side of the semicircular block with the rotor end shaft, it is ensured that the initial reference 0-point position of the rotor design is vertically aligned with the 0-point position of the stator, achieving 100% coincidence between the actual vertical axis of the dynamic / static seal of the dry gas seal and the original design vertical line. The dry gas seal of the unit can be reinstalled in one step, thereby improving the installation quality of the dry gas seal, reducing the economic losses caused by improper disassembly and assembly, and increasing work efficiency by more than 80%. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a schematic diagram of the overall structure of the utility model.

[0013] In the figure: 1. crossbar; 2. semicircular block; 3. slot; 4. support block; 5. rubber pad. DETAILED DESCRIPTION

[0014] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] Example 1

[0016] like Figure 1 As shown, a MAN compressor dry gas seal replacement positioner is provided, comprising a crossbar 1, a semicircular block 2 being fixedly connected to the lower surface of the crossbar 1, a through-type card slot 3 being integrally formed below the front surface of the semicircular block 2, support blocks 4 being fixedly connected to the left and right sides of the lower surface of the crossbar 1, and a rubber pad 5 being fixedly connected to the lower surface of the support block 4;

[0017] By cooperating the slot 3 on the outer side of the semicircular block 2 with the rotor end shaft, it is ensured that the initial reference 0-point position of the rotor design is vertically aligned with the stator 0-point position, achieving 100% coincidence of the actual vertical axis of the dynamic / static seal of the dry gas seal with the original design vertical line. The dry gas seal of the unit can be reinstalled in one step, thereby improving the installation quality of the dry gas seal, reducing the economic losses caused by improper disassembly and assembly, and increasing work efficiency by more than 80%. At the same time, the two support blocks 4 and two rubber pads 5 can better support the positioner above the non-driving end.

[0018] like Figure 1 As shown, the crossbar 1, the semicircular block 2 and the two support blocks 4 are all made of stainless steel;

[0019] Since stainless steel has good corrosion resistance, strength and durability, it can prevent rust or corrosion caused by contact with sealed gas or possible small amounts of impurities, moisture, etc., thereby increasing the service life of the device.

[0020] like Figure 1 As shown, the radius of the slot 3 is 18MM;

[0021] The radius of the slot 3 is 18 mm, which can better adapt to the compressor rotor end shaft and increase the precision of the device.

[0022] like Figure 1 As shown, the length of the crossbar 1 is 550MM;

[0023] The length of the cross bar 1 is set to 550MM, so the device can be placed above the non-driving end when in use, that is, the two support blocks 4 are placed above the non-driving end when in use, which is conducive to the use of the device.

[0024] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
