Description

Technical Field

[0001] The utility model relates to the technical field of oil pipes, in particular to an easily detachable integrated oil pump suction pipe. Background Art

[0002] The oil tank and oil pump of the hot-rolled 1580 hydraulic station are integral equipment. The oil tank is a square box structure (15 meters long × 3 meters wide × 1.6 meters high). The 6 oil pumps are evenly installed on the upper cover of the oil tank. The original design is that each oil pump suction pipe (φ89×2.5 mm stainless steel welded pipe) is inserted into the oil tank and welded to the oil tank as a whole, and then connected to the flange outside the oil tank and the oil pump through a 90° bend connecting pipe with fixed flanges at both ends.

[0003] In the process of implementing this solution, the inventors found that the following problems existed in the prior art and have not been well solved: the disadvantage of this design is that the oil suction pipe inserted into the oil tank leaks due to corrosion and vibration, resulting in large fluctuations in system pressure and even causing production stoppage accidents. Once the oil suction management inserted into the oil tank fails, the oil tank can only be cut and the oil suction pipe can be replaced. The oil tank welding operation requires that all the oil in the tank be drained, which requires a large workload and poses a large safety risk. Utility Model Content

[0004] The main purpose of the utility model is to provide an easily detachable integrated oil pump suction pipe, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] An easily detachable integrated oil pump suction pipe comprises a main oil pipe and an elbow oil pipe, wherein the elbow oil pipe is located at the top end of the main oil pipe, the outer wall of the main oil pipe is provided with flange 1, and the end of the elbow oil pipe away from the main oil pipe is connected with flange 2.

[0007] Preferably, the main oil pipe and the elbow oil pipe are integrated.

[0008] Preferably, the angle between the main oil pipe and the elbow oil pipe is 90°.

[0009] Preferably, the second flange is a flanging slip-on flange.

[0010] Preferably, the main oil pipe is connected to flange 1 by welding, and the elbow oil pipe is connected to flange 2 by welding.

[0011] Preferably, the side ends of flange 1 and flange 2 contain sealing gaskets.

[0012] Preferably, the main oil pipes are all made of stainless steel, with a length of 1.5 meters and an inner diameter of 82 mm.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The oil suction pipeline inserted into the oil tank and the transition pipeline in the middle are changed to an integrated structure. On the basis of the original equipment, a main oil pipe with a diameter slightly smaller than the inner hole diameter of the oil tank flange is directly inserted into the oil tank. A flange 2 matching the pump suction port is welded to one end of the main oil pipe through a degree elbow oil pipe, and a flange 1 consistent with the oil tank is welded in the middle of the main oil pipe. After alignment, it is welded and fixed. This can achieve the effect of quickly replacing the main oil pipe and flange 1 between the oil suction pump and the oil tank without damaging the oil tank body. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1-2 As shown, an easily detachable integrated oil pump suction pipe includes a main oil pipe 1 and an elbow oil pipe 3. The elbow oil pipe 3 is located at the top end of the main oil pipe 1. The outer wall of the main oil pipe 1 is provided with a flange 2. The end of the elbow oil pipe 3 away from the main oil pipe 1 is connected with a flange 2 4.

[0020] Specifically, the main oil pipe 1 and the elbow oil pipe 3 are integrated.

[0021] Specifically, the angle between the main oil pipe 1 and the elbow oil pipe 3 is 90°.

[0022] Specifically, the flange 24 is a flanged slip-on flange.

[0023] Specifically, the main oil pipe 1 is connected to the flange 1 2 by welding, and the elbow oil pipe 3 is connected to the flange 2 4 by welding.

[0024] Specifically, the side ends of flange 1 2 and flange 2 4 contain sealing gaskets.

[0025] Specifically, the main oil pipe 1 is made of stainless steel, has a length of 1.5 meters, and an inner diameter of 82 mm.

[0026] Working principle:

[0027] 1. Surveying: Remove the elbows with fixed flanges on both sides of the original connection between the oil tank and the oil pump, measure the inner diameter of the original oil suction pipe inside the oil tank to be φ84㎜ and the length to be 1370㎜, and measure the distance from the oil pump inlet flange to the elbow;

[0028] 2. Prefabrication: Prefabricate the pipeline according to the surveying and mapping results. Use a 1.5-meter-long, 82-mm-diameter stainless steel pipe, which is the main oil pipe 1. One end is welded with a 90° flange 2 to a flange 4 that matches the pump suction port. Make a flange 2 in the middle to match the oil tank flange. After alignment and installation, weld the flange 2 to the main oil pipe 1. The depth of the pipeline inserted into the oil tank is consistent with the original design.

[0029] 3. Connection: After the pipeline is prefabricated, add sealing gaskets to flange 1 (2) and flange 2 (4), and tighten the flange fixing bolts evenly as required to ensure no leakage.
