The application method of the invention comprises the following steps:

the initial state is as follows: the end of the sliding rod 50 in the scrap iron adsorption cavity 15 is abutted against the cavity wall at one side of the sliding rod 50, the opening and closing plates 71 at the same group of two sides are tightly attached, the opening and closing plates 71 are attached to the contour of the sliding rod 50, and the torsion spring 63 is in a loose state and is not stressed.

Preparation: the transmission shaft 21 is connected with the motor through a coupling, the oil inlet and outlet holes 14 on two sides are respectively connected with pipelines, and the whole device is connected into an oil way.

When the oil pump is used, the motor connected with the transmission shaft 21 is started, the transmission shaft 21 rotates, the transmission shaft 21 drives the cylinder body in the plunger pump assembly 20 to rotate in the cylinder body rotating cavity 12, at the moment, the plunger pump assembly 20 absorbs oil from one end of the oil inlet and outlet hole 14 through internal volume change and discharges the oil from the other end of the oil inlet and outlet hole 14, in the process, after the oil enters the oil inlet and outlet hole 14 on one side, part of the oil enters the detection oil hole 37 on one side under high pressure forming the action of a plunger, and enters the scrap iron adsorption cavity 15 and the viscosity detection cavity 16 through the oil pipe C33 and the electric control valve 31 respectively through the electric control valve 31 and the oil pipe A32, and the oil entering the scrap iron adsorption cavity 15 and the viscosity detection cavity 16 flows through the inside and is discharged from the detection oil hole 37 on the low pressure side through a pipeline on the other side, and is discharged from the oil suction and discharge hole 36 along with the rest of the oil.

When oil flows in the scrap iron adsorption cavity 15, the oil flows along the annular cavity wall of the scrap iron adsorption cavity 15, during the flowing process, scrap iron particles suspended in the oil are adsorbed by the sliding rod 50, after a period of time, the electromagnet A72 is started to generate magnetism, the part of the opening and closing plate 71 in the arc groove 70 is attracted by the electromagnet A72 and moves away from the drum communication cavity 17 against the elastic force of the spring 73, the opening and closing plates 71 on two sides of the scrap iron adsorption cavity 15 are opened and closed, the electromagnet B80 is started to generate magnetic pole attraction to the sliding rod 50 opposite to one end of the sliding rod 50, the sliding rod 50 slides along the sliding rod cavity 19 under the attraction of the electromagnet B80, the part of the sliding rod 50 on the side away from the electromagnet B80 completely enters the scrap iron collecting cavity 61, the electromagnet A72 is closed after that under the elastic force of the spring 73, the spring 73 pushes the opening and closing plates 71 on two sides to be closed again, the electromagnet B80 will produce the same magnetic pole just facing one end with the slide bar 50, the slide bar 50 will move to the iron fillings adsorption chamber 15 again under the repulsion action of the electromagnet B80 until the slide bar is abutted against the wall of the iron fillings adsorption chamber 15, in this process, because the profile of the opening plate 71 is completely attached to the outer surface of the slide bar 50, in the resetting process of the slide bar 50, the iron fillings adsorbed on the slide bar 50 will not return to the iron fillings adsorption chamber 15 and remain in the iron fillings collection chamber 61 under the action of the opening plate 71, because the part of the slide bar 50 in the viscosity detection chamber 16 has no magnetism, the iron fillings will be resuspended in the iron fillings collection chamber 61, the staff can judge the abrasion condition of the internal parts by observing the turbidity degree of the oil in the iron fillings collection chamber 61, and the more the iron fillings are gathered in the iron fillings collection chamber 61.

In the above process, the control chip externally connected with the control valve 31 will control the oil flow and the flow velocity in the scrap iron adsorption cavity 15 and the viscosity detection cavity 16 to be always inconvenient, so as to avoid the influence of the change of the flow velocity on the deflection angle of the rotary cylinder 60.
