[0017] 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 with reference to specific illustrations.

[0018] See also Figures 1 to 4 An improved structure of a large-flow pipeline filter is shown, comprising an RF1300 return oil filter 100, on which an oil inlet 110 and an oil outlet 120 connected to a main oil inlet and a main oil outlet are respectively provided, and a first transition flange 111 and a second transition flange 121 are respectively provided on the oil inlet 110 and the oil outlet 120, and a branch oil inlet 112 and a branch oil outlet 122 connected to the oil inlet 110 and the oil outlet 120 are respectively provided on the sides of the first transition flange 111 and the second transition flange 121.

[0019] The RF1300 return oil filter 100 is provided with a differential pressure transmitter 200 connected to the branch oil inlet 112 and the branch oil outlet 122 and used to detect the pressure difference change between the oil inlet 110 and the oil outlet 120. The differential pressure transmitter 200 in this embodiment is provided with a block 210 connected to the branch oil inlet 112 and the branch oil outlet 122, and the block 210 is provided with a block pipe joint 211 connected to the branch oil inlet 112 and the branch oil outlet 122.

[0020] The branch oil inlet 112 is provided with an oil inlet pipe joint 112a and a first steel pipe 112b provided on the oil inlet pipe joint 112a and connected to the block pipe joint 211. Similarly, the branch oil outlet 122 in this embodiment is provided with an oil outlet pipe joint 122a and a right angle combined joint 122b provided on the oil outlet pipe joint 122a and connected to the block pipe joint 211.

[0021] A screw plug 130 is provided on the top of the RF1300 oil return filter 100. The design of the screw plug 130 is to cancel the original signal filter and install the screw plug at the installation position of the RF1300 oil return filter 100.

[0022] When the utility model is used, when a large flow of oil flows into the RF1300 return oil filter 100 from the main oil inlet, the pressure differential transmitter 200 is installed on the block 210. The pressure differential transmitter 200 can monitor the pressure difference change of the oil inlet 110 and the oil outlet 120 of the RF1300 return oil filter 100, thereby determining whether the RF1300 return oil filter 100 is blocked, so as to replace the filter element in time.
