[0047] The following will be combined with the drawings in the present application to describe the technical solutions in the present application clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based upon the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of protection of the present application. Figures 1-4 The embodiments of the present application are described as follows:

[0048] Embodiment 1:

[0049] As shown in Figure 1 , Figure 2 , the manufacturing process of the shielding sleeve of the shielding pump provided by the embodiments of the present application includes the manufacturing process of the shielding sleeve of the shielding pump stator, and the manufacturing process of the shielding sleeve of the shielding pump stator comprises:

[0050] Step A1: measure the actual size of the shield pump stator; length is generally measured by the stator head plate; circumference is measured by the actual diameter x π (generally take 3.14): that is, L = πR;

[0051] Step A2: select the material of the stator shield sleeve, and then roll, weld, and correct the circle to obtain the first cylinder material;

[0052] The special material for the stator is generally Hastelloy alloy, with a thickness of 0.3-0.5mm, and the error of the circumference blanking should not be greater than 0.05-0.10mm; the length blanking takes appropriate size to avoid waste as much as possible, and adds 0.20-0.80mm to the calculated size for rough blanking [i.e. L. = L + (0.20-0.80)], first mark the position with a needle and ruler, and then accurately blank with a shearing machine. (Note: The shearing machine should be operated by a special person to prevent injury due to misoperation.)

[0053] Welding is divided into three specific steps: pre-welding inspection, welding, and weld inspection coloring:

[0054] Pre-welding inspection: whether the gas cylinder has sufficient gas; whether the gas pipe is clean; whether the line is unobstructed; whether there is wind affecting the welding process; whether the plate cut is flush and free of burrs; whether the welding platform, pressing plate, etc. are clean, etc. After all the inspections are qualified, the next step of welding operation can be carried out.

[0055] Welding: use the special welding operation table for the shield sleeve, fix the polished and cleaned cylinder material inside and outside the platform, adjust the gap between the pressing plates to about 2mm-5mm, use a cold welding machine, the welding gun is placed on a semi-automatic cutting frame, and the two are used together, adjust the welding parameters, and weld once to pass the inspection.

[0056] Weld inspection and coloring: use special tools to observe the appearance of the weld, gently correct uneven places with special tools, and repair high points with special tools to make them flat.

[0057] Correcting the circle can use the plate rolling machine to correct multiple times until the first cylinder material section is smooth. (Note: When rolling, fine-tune to prevent the cylinder material from deforming too much.)

[0058] Step A3: First end plate processing: point weld the first end plate material on the prepared first end plate processing tooling, and hand it over to the lathe for processing;

[0059] Step A4: reassemble and seal the first end plate:

[0060] Clean the first cylinder material (cleaning treatment with alcohol), one end of the first cylinder material is fastened by the first cylinder material rotating tool, the other end of the first cylinder material is inserted into the cleaned stator, the first cylinder material rotating tool is knocked to make the first cylinder material slowly enter the stator (the operation is generally cooperated by multiple persons, one person observes the condition of the first cylinder material entering, one person holds the tool, and one person knocks), the concentricity of the first cylinder material and the insulating sleeve is paid attention to at all times during the reinstallation, and finally the first cylinder material is reinstalled until the same length of the first cylinder material is left at both ends;

[0061] The first end plate is installed to both ends of the first cylinder material, is pressed tightly and is flattened, the excess part of the first end plate is cut off, burrs are trimmed, manual welding is performed after cleaning, and PT detection treatment is performed on the welding seam;

[0062] Step A5: pressing, the blind plate is added to both ends of the first cylinder material after sealing in step A4, water is injected to press to the first pressure (1.5-2.0 Mpa), and the pressure is maintained for a second time length (several hours).

[0063] Preferably, if the stator shielding sleeve is loose, it needs to be redone: the dismounting method is that a notch is cut on the sleeve by using an angle grinder, the sleeve is clamped by using a vise, the vise is tightly bound by using a rope, and the sleeve is pulled gently until the sleeve is taken out.

[0064] As shown in Figure 2 The manufacturing process of the shielding sleeve of the shielding pump rotor further includes a manufacturing process of a shielding sleeve of a shielding pump rotor.

[0065] The manufacturing process of the shielding sleeve of the shielding pump rotor includes:

[0066] Step B1: the old shielding sleeve of the shielding pump rotor is dismounted, and the shielding pump rotor with the dismounted shielding sleeve is cleaned.

[0067] The specific steps of dismounting the old rotor sleeve are that the rotor is dismounted to a lathe, the welding seams of the end plates at both ends of the rotor are turned, a seam is cut on the original sleeve (attention is paid to not damaging the internal steel sheet), and the old sleeve is dismounted by using a special tool (note that the internal sleeve may contain materials, and protective measures are taken).

[0068] The specific steps of cleaning the shielding pump rotor with the dismounted shielding sleeve are that the shielding pump rotor with the dismounted shielding sleeve is soaked in water for about 5-10 hours, the shielding pump rotor is taken out and dried by using a special oven for about 6-10 hours, and the steel sheet gap of the shielding pump rotor is cleaned by using alcohol gauze and the like after drying.

[0069] Step B2: the size of the cleaned shielding pump rotor is measured, the material of the shielding sleeve of the rotor is selected, and the shielding sleeve is cut.

[0070] The length of the shielding pump rotor is generally measured by the two end plates of the stator; the circumference is measured by the actual diameter x π (generally 3.14); that is, L = πR. The shielding pump rotor is generally made of 316L stainless steel plate, with a thickness of 0.3-0.5 mm, and the error of the circumference shall not be greater than 0.05-0.10 mm. The length is cut to an appropriate size to avoid waste as much as possible.

[0071] Preferably, when cutting the circumference, 10-20 mm is added to the calculated size for rough cutting, that is, L = L + 10-20. First, mark the position with a ruler and then accurately cut it with a plate shearing machine. (Note: The plate shearing machine should be operated by a special person to prevent injury due to misoperation.)

[0072] Step B3: Adjust after rough rolling: The shielding sleeve material of the cut rotor is rolled into a second cylinder on the plate rolling machine. The rolled second cylinder is wrapped around the rotor, clamped to the surface of the rotor using a fastener, and gently tapped with a leather hammer to make the second cylinder fit more closely with the shielding pump rotor. Mark the overlap between the second cylinder and the shielding pump rotor with a marking needle.

[0073] Step B4: According to the mark of the overlap between the second cylinder and the shielding pump rotor, the second cylinder obtained in step B3 is cut and rolled twice, and then the second cylinder is welded and sealed.

[0074] The specific steps for the second rolling are to use the plate rolling machine to roll repeatedly, and the arc surface is uniformly best.

[0075] The specific steps for the second cutting are to use a ruler to mark a line, measure the part to be cut with a caliper, subtract 0.3-0.5 mm from the reference line, clamp it to the plate shearing machine, and cut it after multiple confirmations.

[0076] Step B5: Roundness correction: The welded second cylinder obtained in step B4 is corrected multiple times using the plate rolling machine to obtain the roundness-corrected second cylinder.

[0077] Step B6: Once-sealing after reassembly: First, clean the roundness-corrected second cylinder. Use the cylinder tooling to clamp the roundness-corrected second cylinder to the lathe and find the center. One end of the roundness-corrected second cylinder is fastened and centered using the cylinder tooling. The other end of the roundness-corrected second cylinder is aligned with the cleaned shielding pump rotor. Slowly push the shielding pump rotor into the roundness-corrected second cylinder using the hydraulic tooling center. Pay attention to the concentricity of the shielding pump rotor and the roundness-corrected second cylinder during reassembly. After cutting off the excess part of the roundness-corrected second cylinder, trim the burrs. After cleaning, install the second cylinder and the processed second end plate, and manually weld and seal. Perform PT detection and processing on the weld.

[0078] Preferably, if the resistance is large when the shielding pump rotor is pushed into the roundness-corrected second cylinder using the hydraulic tooling center, hot water can be used to pour the sleeve (note that water cannot be poured onto the rotor).

[0079] Preferably, one sealing and secondary drying are carried out, the excess part is cut off and the burr is trimmed, the welding is carried out after the trimming, and the welding is put into a drying oven for drying for 12-20 hours (the optimal drying temperature range is 200-211 DEG C).

[0080] Preferably, the final inspection is carried out, and all the welds are carefully inspected, and the PT is colored after no error is found.
