[0043] The utility model will be explained below with specific embodiment, but is not the limitation of the utility model.

[0044] Example one

[0045] As Figures 1-6 Shown, in the embodiment, provide a kind of oil liquid abrasive particle monitoring sensor, including monitoring pipe 1, monitoring pipe 1 is the open-ended cylinder;Two shunt pipes 2 are arranged in parallel in monitoring pipe 1;The two ends of monitoring pipe 1 are provided with end cover 3 respectively;Wherein, the outer wall of two end covers 3 is connected with tee pipe 4, and one end of tee pipe 4 is connected with external oil circuit;

[0046] When end cover 3 is connected in the end of monitoring pipe 1, the other two ends of tee pipe 4 are communicated with two shunt pipes 2 respectively.

[0047] The end of the shunt pipe 2 is provided with a connecting pipe 202 with a smaller outer diameter than the shunt pipe 2, and the connection between the shunt pipe 2 and the connecting pipe 202 and the connection between the connecting pipe 202 and the three-way pipe 4 are both provided with sealing surfaces 203, and the sealing surfaces 203 are provided with sealing rings 9 between the sealing surfaces 203 and the end cavity of the three-way pipe 4.

[0048] The inner cavity of the monitoring pipe 1 is in an oval shape with a large middle part and small ends, and the bottom center of the monitoring pipe 1 is connected with a leak detection pipe 10 in a transparent shape, when the shunt pipe 2 has a small amount of leakage, the oil will flow to the center of the monitoring pipe 1, and then flow into the inside of the leak detection pipe 10, at this time, whether the oil exists in the leak detection pipe 10 can be observed to know whether the shunt pipe 2 has oil leakage.

[0049] The end of the three-way pipe 4 connected with the external oil circuit is provided with an internal thread, and the outer wall of the end is further provided with a hexagonal block.

[0050] The shunt pipe 2 is externally wound with a coil 11.

[0051] The upper part of the monitoring pipe 1 is connected with a wire box 12 for containing a processing module, and the coil 11 is electrically connected with the processing module in the wire box 12.

[0052] Working process:

[0053] The oil flows from the external oil circuit into the monitoring pipe 1 through the threaded port of the three-way pipe 4, and is evenly divided into two paths at the shunt pipe 2, and the oil circuit is thinned to better monitor the oil, when the oil flows, the coil 11 outside the shunt pipe 2 generates an alternating magnetic field, the metal particles in the oil cut the magnetic induction lines to generate an induced current, the amplitude of which is proportional to the particle size and concentration. These electrical signals are transmitted to the processing module in the wire box 12 through the cable, and are converted into oil contamination data after filtering, amplification and algorithm analysis.

[0054] The oval cavity of the monitoring pipe 1 forms a "funnel effect": if the shunt pipe 2 leaks, the leaked oil will flow along the inner wall of the monitoring pipe 1 to the leak detection pipe 10 at the lowest point. Since the leak detection pipe 10 is made of transparent material, the operator can directly visually confirm whether there is oil accumulation to verify the sealing reliability.

[0055] Example two

[0056] As shown in Figure 5 In order to fix the two shunt pipes 2 in parallel in the monitoring pipe 1, the two ends of the monitoring pipe 1 are provided with positioning plates 5, the side walls of the positioning plates 5 are provided with positioning holes 501 for inserting the shunt pipes 2, and the two ends of the shunt pipes 2 are fixedly connected with baffles 201, and the baffles 201 are integrally formed with the shunt pipes 2.

[0057] When the end of the shunt pipe 2 is inserted into the inside of the positioning hole 501, the baffle 201 abuts against the inner wall of the positioning plate 5.

[0058] Two guide grooves 101 are symmetrically arranged on the side wall of the monitoring pipe 1, and two ear plates two 502 are symmetrically arranged on the two sides of the positioning plate 5.

[0059] When the positioning plate 5 is installed at the end of the monitoring pipe 1, the ear plate two 502 is located in the guide groove 101.

[0060] The ear plate two 501 is provided with a fixing bolt 6, and the threaded end of the fixing bolt 6 penetrates the side wall of the ear plate two 501 and is engaged and connected to the side wall of the monitoring pipe 1.

[0061] Working process:

[0062] During installation, first, the ear plate two 502 of the positioning plate 5 is slid along the guide groove 101 of the side wall of the monitoring pipe 1 to make the positioning hole 501 aligned with the inside of the monitoring pipe 1. The end of the shunt pipe 2 with the baffle 201 is inserted into the positioning hole 501, and the baffle 201 abuts against the inner wall of the positioning plate 5 to complete the preliminary fixing. Then, the fixing bolt 6 is screwed in, the threaded end penetrates the ear plate two 502, and is engaged with the side wall of the monitoring pipe 1 to generate an axial clamping force to make the positioning plate 5 adhere to the end face of the monitoring pipe 1.

[0063] After the oil liquid enters the monitoring pipe 1 from the external oil path through the tee pipe 4, it is uniformly shunted under the guidance of the double shunt pipes 2. The positioning plate 5 ensures that the shunt pipes 2 remain absolutely parallel, so that the oil liquid flow rate remains consistent in the double pipes, and the symmetry of the abrasive particle detection is improved.

[0064] Example three

[0065] As shown in Figures 1-4 On the basis of example two, in order to be able to install two positioning plates 5 at the two ends of the monitoring pipe 1, two lead screws 7 are symmetrically arranged on the side wall of any end cover 3, two sink grooves 301 are symmetrically arranged on the side wall of the other end cover 3, a nut 8 is arranged in the inside of the sink groove 301, the threaded end of the lead screw 7 penetrates the two positioning plates 5 and extends into the sink groove 301 and is engaged and connected with the nut 8, and a through hole 503 for the lead screw 7 to penetrate is arranged on the side wall of the positioning plate 5.

[0066] Two ear plates one 302 are symmetrically arranged on the side wall of the end cover 3.

[0067] When the end cover 3 is installed at the end of the monitoring pipe 1, the ear plate one 302 is located in the guide groove 101.

[0068] The cooperation of the guide groove 101 and the ear plate one 302 and the ear plate two 502 can make the end cover 3 and the positioning plate 5 keep consistent in angle, so that the through hole 503 on the positioning plate 5 can be aligned with the screw rod 7 and the sunken groove 301 on the end cover 3 after installation, thereby facilitating the threading of the screw rod 7.

[0069] Finally, it should be noted that the above examples are only used to illustrate and not limit the technical solutions of the present application. Although the present application has been described in detail with reference to the above examples, those skilled in the art should understand that the present application can still be modified or replaced by equivalents without departing from the spirit and scope of the present application. Any modification or partial replacement should be covered in the scope of the claims of the present application.
