[0041] Example:
[0042] See also Figure 1-4 A screw air compressor head oil leakage transition device comprises an SKK head 1, an oil tank 2 and an oil leakage transition assembly 8, wherein the bottom end of the SKK head 1 is fixedly connected with a connecting seat 4, the connecting seat 4 is provided with an oil leakage hole 6 connected with the inside of the SKK head 1, and the connecting seat 4 is provided with a plurality of threaded holes 5, the upper end of the oil tank 2 is fixedly connected with a head seat 3, the head seat 3 is provided with an oil return hole 7, and the head seat 3 is provided with a plurality of assembly holes 9, the oil return hole 7 is connected with the inner cavity of the oil tank 2, the oil leakage transition assembly 8 comprises an oil leakage hole connecting block 801, the oil leakage hole connecting block 801 matches the oil leakage hole 6, and the bottom end of the oil leakage hole connecting block 801 is integrally formed with an oil return hole connecting block 802, the threaded hole 5 matches the assembly hole 9, and the plurality of threaded holes 5 and the plurality of assembly holes 9 are all distributed in a cross shape.
[0043] A screw air compressor is a common compressed air equipment used to compress air into high-pressure gas. The SKK head is an important component of the screw air compressor. It is the core component of the screw air compressor and is responsible for achieving efficient and reliable compressed air operation. An oil tank 2 is provided on the lower side of the SKK head 1. In the existing solution, the user docks the connecting seat 4 with the head seat 3 to align the multiple threaded holes 5 with the multiple assembly holes 9. At this time, the oil drain hole 6 will also be aligned with the oil return hole 7. Multiple screws are used to penetrate the assembly holes 9 and the threaded holes 5 from the bottom of the head seat 3 respectively, so that the head seat 3 is tightly connected to the connecting seat 4, so that the oil drain hole 6 is connected to the oil return hole 7. The purpose of setting the oil tank 2 is to collect the lubricating oil supplied by the lubrication system to the inside of the SKK head and return it to the oil tank 2, so as to promote the reflux and circulation of the lubricating oil. A valve is usually installed inside the oil drain hole 6 to facilitate the control of the discharge of the lubricating oil.
[0044] See also Figure 5-6 The outer end of the oil drain hole connecting block 801 is engraved with a thread, the inner wall of the oil drain hole 6 is provided with a thread groove matching the thread, and the oil return hole connecting block 802 matches the oil return hole 7.
[0045] In the existing scheme, the connecting seat 4 and the head seat 3 are connected by a simple docking method. There is a lack of an oil leakage transition device between the oil drain hole 6 and the oil return hole 7, which makes it easy for oil leakage to occur between the connecting seat 4 and the head seat 3. Therefore, this scheme is provided with an oil leakage transition component 8. Before connecting the SKK head 1 to the oil tank 2, the user can use Loctite 222# detachable threaded adhesive to thread the oil drain hole connecting block 801 with the inner wall of the oil drain hole 6, and then apply a proper amount of Loctite 510# flat sealant on the upper surface of the head seat 3, that is, the part where the head seat 3 and the connecting seat 4 abut, and finally insert the oil return hole connecting block 802 into the oil return hole 7, and dock the connecting seat 4 with the head seat 3, and finally use multiple screws to penetrate the assembly hole 9 and the threaded screw from the bottom of the head seat 3 respectively. The grooved holes 5 make the head seat 3 and the connecting seat 4 tightly connected, the thread glue can ensure the sealing between the outer wall of the oil drain hole connecting block 801 and the inner wall of the oil drain hole 6, and ensure the stability of the connection of the oil drain hole connecting block 801, the flat sealant can effectively improve the sealing between the connecting seat 4 and the head seat 3, so as to ensure that the oil drain hole 6 and the oil return hole 7 are completely sealed, and the lubricating oil discharged from the inside of the SKK head 1 is discharged into the oil return hole 7 through the oil drain hole connecting block 801 and the oil return hole connecting block 802. The oil drain transition component 8 plays a transitional role, changing the oil drain hole 6 and the oil return hole 7 from the original docking connection mode to an insertion and docking connection mode, avoiding the lubricating oil from directly contacting the gap at the connection between the head seat 3 and the connecting seat 4, thereby preventing oil leakage and oil seepage.
[0046] See also Figure 3-4The bottom end of the connecting seat 4 is integrally formed with an annular docking block 10, which is arranged on the outside of the plurality of threaded holes 5. The head seat 3 is provided with an annular docking groove 11 matching the annular docking block 10, and an annular rubber is installed on the inner wall of the annular docking groove 11.
[0047] In this solution, when the head seat 3 is docked with the connecting seat 4, the annular docking block 10 will be embedded in the annular docking groove 11. The annular docking block 10 squeezes the annular rubber pad installed on the inner wall of the annular docking groove 11, thereby sealing the inner side of the annular docking groove 11, thereby playing a secondary anti-leakage role, further enhancing the oil leakage prevention effect of the device.
[0048] Working principle:
[0049] Before connecting the SKK machine head 1 to the oil tank 2, the user can use Loctite 222# detachable threaded adhesive to thread the oil drain hole connection block 801 with the inner wall of the oil drain hole 6, and then apply a proper amount of Loctite 510# flat sealant on the upper surface of the machine head seat 3, that is, the part where the machine head seat 3 and the connecting seat 4 abut, and finally insert the oil return hole connection block 802 into the oil return hole 7, and dock the connecting seat 4 with the machine head seat 3, and finally use multiple screws to penetrate the assembly hole 9 and the threaded hole 5 from the bottom of the machine head seat 3, so that the machine head seat 3 and the connecting seat 4 are tightly connected, and the lubricating oil discharged from the inside of the SKK machine head 1 is discharged through the oil drain hole The connecting block 801 and the return oil hole connecting block 802 are internally discharged into the return oil hole 7, and the oil leakage transition component 8 plays a transitional role, changing the oil leakage hole 6 and the oil return hole 7 from the original docking connection mode to an insertion and docking connection mode, avoiding the lubricating oil from directly contacting the gap at the connection between the head seat 3 and the connecting seat 4, thereby eliminating oil leakage and oil seepage. When the head seat 3 is docked with the connecting seat 4, the annular docking block 10 will be embedded in the annular docking groove 11, and the annular docking block 10 squeezes the annular rubber pad installed on the inner wall of the annular docking groove 11, which has the effect of sealing the inner side of the annular docking groove 11, thereby playing a secondary anti-leakage role.
[0050] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto.
