[0034] like Figures 1 to 6 As shown, the oil pump cover is used to cover the oil pump, which is at least partially located inside the oil pump cover. The oil pump cover includes a housing 10 and an observation window 20. The housing 10 has an installation notch 13, and the observation window 20 is located on the housing 10. The observation window 20 covers at least part of the installation notch 13. The observation window 20 is made of transparent or semi-transparent material so that the operator can observe the oil pump through the observation window 20.
[0035] By setting an installation notch 13 on the housing 10 and setting an observation window 20 at the installation notch 13, the observation window 20 is made of transparent or semi-transparent material, and the staff can directly observe the condition of the oil pump through the observation window 20 without opening the pump cover, which simplifies the inspection operation steps, saves inspection time and improves inspection efficiency, and helps to detect oil leaks in a timely manner.
[0036] Specifically, the observation window 20 is detachably connected to the housing 10. By providing a detachable observation window 20 on the housing 10, it can be disassembled and replaced, and it is also convenient to perform daily cleaning of the observation window 20.
[0037] Furthermore, the housing 10 is provided with a slot 14, located near the mounting notch 13, and the viewing window 20 is at least partially inserted into the slot 14. By providing the slot 14 near the mounting notch 13 on the housing 10, when the viewing window 20 is inserted into the slot 14, the viewing window 20 covers at least part of the mounting notch 13. This not only limits the viewing window 20 using the slot 14 but also facilitates the installation and removal of the viewing window 20. When it is necessary to remove the viewing window 20, it can simply be pulled out of the slot 14. Compared to designing a rotating viewing window 20, designing a slot 14 saves more space and is less prone to damage.
[0038] Optionally, the housing 10 includes a base 111 and a baffle 112. A mounting notch 13 is provided on the base 111, and the baffle 112 is fixedly connected to the outer side of the base 111. The baffle 112 and the base 111 together form a slot 14. By setting the baffle 112 and the base 111 to form the slot 14, the structure is simple, easy to manufacture, and can be applied to a variety of different situations to meet the setting requirements of observation windows 20 of different shapes.
[0039] In this embodiment, the housing 10 includes a main housing 11 and a cover 12, with the cover 12 covering the top of the main housing 11. The main housing 11 includes a base 111 and a baffle 112, which together form a slot 14. An observation window 20 is detachably disposed within the slot 14, located between the base 111 and the baffle 112. The cover 12 can be detachably fixed to the top of the main housing 11 by screws or snap-fitting; the baffle 112 can be fixed to the base 111 by screws or welding.
[0040] Optionally, the slot 14 has a bearing surface, and the viewing window 20 is placed on the bearing surface and at least partially inserted into the slot 14 in the vertical direction. By using the bottom wall of the slot 14 as the bearing surface, the viewing window 20 is vertically inserted into the slot 14. The bearing surface can support the viewing window 20 from the bottom, and the slot 14 limits the viewing window 20 in all directions. No other method is needed to fix the viewing window 20, and the accuracy of the installation position of the viewing window 20 can be ensured. Compared to designing a horizontally pull-out viewing window 20, using a vertically pull-out design makes it less likely for the viewing window 20 to be obstructed by other structures in practical applications, providing suitable space for the viewing window 20 to move.
[0041] Specifically, the observation window 20 includes a shielding part 21 and an operating part 22. The operating part 22 is connected to the shielding part 21, which is inserted into the slot 14, while the operating part 22 is located outside the slot 14. By providing the shielding part 21 and the operating part 22, the shielding part 21 is inserted into the slot 14 to shield the mounting notch 13, and the operating part 22 is located outside the slot 14, making it convenient for staff to operate the operating part 22 to place or remove the observation window 20.
[0042] In this embodiment, the top of the shielding part 21 is provided with two operating parts 22, which are spaced apart and symmetrically arranged on the shielding part 21. After the viewing window 20 is installed, the operating parts 22 are attached to the side of the cover 12.
[0043] Optionally, the housing 10 is provided with a receiving opening 15, which communicates with the mounting notch 13. The observation window 20 is provided with a clearance opening 23, and the oil pump is inserted into the receiving opening 15. The shape of the clearance opening 23 matches the shape of the top surface of the oil pump. By providing the receiving opening 15 and the clearance opening 23 on the observation window 20, and by having the oil pump inserted into the receiving opening 15 with the top surface of the oil pump matching the shape of the clearance opening 23, it is helpful to arrange the positions of the observation window 20 and the oil pump.
[0044] Optionally, the observation window 20 is positioned at a height higher than that of the oil pump; the length of the observation window 20 ranges from 50cm to 70cm; and the width of the observation window 20 ranges from 35cm to 60cm. By rationally designing the height and dimensions of the observation window 20, it is ensured that personnel can directly observe the status of the oil pump through the observation window 20.
[0045] Under normal circumstances, the distance between the personnel and the oil pump cover during inspections should always be within the range of 0.025m-0.17m; see [link / reference] Figure 6 Specifically, based on the principle of incident light refraction and assuming the average viewing angle θ of the worker is 120°, the horizontal dimensions of the observation window 20 are calculated. The three vertices of the triangle are A, B, and C. Assuming the worker stands at vertex A, and given the average viewing angle θ = 120°, and taking the distance D = 0.17m between the worker and the observation window 20, the horizontal length BC of the observation window 20 is calculated to be 58.89cm. Correspondingly, based on the specific location of the mechanical seal of the oil pump, the vertical width of the observation window 20 is calculated.
[0046] Optionally, the observation window 20 is a one-piece structure; the observation window 20 is made of plexiglass. By designing the observation window 20 as a one-piece structure, it is less affected by severe weather and has a long service life; using plexiglass (i.e., acrylic PMMA sheet) material, it has high hardness and strength, impact resistance, good surface gloss and transparency, corrosion resistance, resistance to ultraviolet radiation, meets explosion-proof requirements, and has a long service life. In other embodiments, the observation window 20 can also be made of fire-retardant polyvinyl chloride (PVC) or polystyrene (PS) material.
[0047] Optionally, the thickness of the observation window 20 ranges from 3 to 7 mm. The thickness of the observation window 20 is related to the material. Based on the size and material of the observation window 20, finite element analysis is used to calculate the optimal thickness of the observation window 20 under concentrated wind load conditions, based on the deformation of the observation window 20 with different thicknesses.
[0048] In this embodiment, the observation window 20 has a total length of 60cm and a total width of 47cm, and a thickness of 5mm; the operating part 22 of the observation window 20 is square, with a side length of 6cm; the radius of the clearance opening 23 on the observation window 20 is 16cm. The specific size and shape of the clearance opening 23 can be adaptively adjusted according to the size and shape of the oil pump.
[0049] The following is a detailed description of the modification and usage process of the oil pump cover:
[0050] The oil pump cover in this embodiment can be directly processed or modified from an existing pump cover. The specific process is as follows: inspect the existing pump cover to determine whether it meets the basic conditions for modification, and measure the relevant dimensions to formulate design drawings; cut an installation notch 13 on the base 111 according to the design drawings and set a baffle 112 to form a slot 14, and cut and process the observation window 20 according to the design drawings; insert the observation window 20 vertically into the slot 14; finally, conduct an inspection efficiency test, measure and record the average inspection time of the staff, and determine the inspection efficiency.
[0051] The oil pump cover with observation window 20 provided in this embodiment is easy to use, cost-effective, and has a long service life. It can effectively improve inspection efficiency, make it easier for staff to detect leaks in the mechanical seal of the oil pump in a timely manner, and thus take timely measures to avoid serious fires, explosions and other accidents, and ensure the safety of staff.
