Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
The embodiment of the invention comprises the following steps:
as shown in fig. 2-8, the pressure collecting device of the oil filter includes a circular column 3, and an oil outlet hole, which is denoted as a first oil outlet hole 31, is formed in the middle of the column 3 along the axial direction thereof; four oil inlets are formed in the edge area of the first oil outlet on the cylinder 3, and are marked as first oil inlets 32, and each first oil inlet 32 is axially arranged in a through manner along the cylinder. The number of the first oil inlet holes 32 is four, and the first oil inlet holes are uniformly distributed along the circumferential direction of the cylinder. In this embodiment, in order to be adapted to an oil filter (shown in fig. 1) in the prior art, four corresponding oil inlets are also provided. For the sake of distinction, the oil inlet hole of the oil filter in the prior art is referred to as a second oil inlet hole 22, and the oil outlet hole is referred to as a second oil outlet hole 21. Of course, in other embodiments, two, three or six oil inlet holes may be provided in the cylinder.
The first oil outlet hole 31 is threadedly fitted with the connecting rod 5, and the connecting rod 5 is hollow in the axial direction. The upper portion of the connecting rod 5 has a threaded bore 51 for threaded assembly with an oil filter base, similar to the assembly of prior art oil filters with oil filter bases. In this embodiment, because designed oil filter pressure acquisition device, consequently oil filter no longer directly with the assembly of oil filter base.
The upper end of the cylinder 3 is provided with a sealing groove at the outer edge of the first oil inlet 42 for installing a sealing ring, and the sealing groove is marked as a first sealing groove 33 for ensuring the sealing property of the connection between the cylinder and the oil filter base.
The middle part of connecting rod 5 is light beam section 53, and the upper and lower both sides of light beam section 53 encircle respectively and are equipped with a seal groove for the installation sealing washer. The two seal grooves are designated as a second seal groove 54 and a third seal groove 55, and are used for mounting O-rings. The sealing rings in the second sealing groove 54 and the third sealing groove 55 realize the sealing assembly of the light column section 53 and the inner wall of the first oil outlet hole 31.
A communication oil hole 56 is formed in the middle portion, i.e., the right-hand cylindrical portion, of the connecting rod 5, and the communication oil hole 56 is disposed between the second seal groove 54 and the third seal groove 55. The communication oil hole 56 is radially provided and communicates the inner cavity of the connecting rod 5 with the outside of the connecting rod 5.
The cylinder 3 is provided with a detection oil hole 36 in the radial direction, the detection oil hole 36 is provided corresponding to the communication oil hole 56, and the vertical position of the detection oil hole 36 coincides with the communication oil hole 56. In order to make the oil discharged from the oil outlet hole smoothly flow to the communicating oil hole and the detecting oil hole, a first communicating groove 34 is formed around the inner wall of the first oil outlet hole 31, and the first communicating groove 34 passes through the detecting oil hole 36. Design like this, even the connecting rod can not guarantee to detect the oilhole when assembling with the cylinder and communicate the oilhole position relative, also can satisfy the normal flow of fluid to detecting oilhole department to detect.
The cylinder is provided with a pressure acquisition piece, and an acquisition part of the pressure acquisition piece is arranged corresponding to the detection oil hole so as to acquire the oil pressure at the detection oil hole. In this embodiment, pressure acquisition spare adopts pressure transmitter 4, and the periphery wall of cylinder 3 is equipped with installation screw hole 35 along radial, and 4 screw-thread assemblies of pressure transmitter are in this installation screw hole, and installation screw hole 35 and detection oilhole 36 intercommunication, and both coaxial settings.
