[0017] The beneficial effects of the present invention are:

[0018] (1) The present invention detects the hydraulic pressure and flow rate of the oil at the oil outlet end through the hydraulic sensor and flow sensor on the sphere. When the oil flows, the turbine propeller can drive the movable sleeve rod and the screw nut to rotate on the structural bearing, and the connection between the screw nut and the traction screw rod can drive the traction screw rod to move upward, so that the traction screw rod can be extended into the piston cylinder to squeeze the trigger piston, so that it overcomes the air pressure in the piston cylinder and its own weight to push the metal push rod at the top of the trigger piston into the trigger seat, thereby making the metal push rod and the inner convex block on the inner side of the power supply conductive half ring and the equipment conductive half ring in the trigger seat. When the oil pump is in use, when there is no leakage in the oil pump, the hydraulic pressure and rotation speed at the oil outlet end will be sufficient to drive the turbine propeller and trigger the warning light; when there is leakage in the oil pump, the hydraulic pressure and rotation speed at the oil outlet end will be insufficient to drive the turbine propeller, thereby realizing the leakage detection function of the oil pump through the mechanical triggering method and the use of two sets of sensors.

[0019] (2) The present invention imparts magnetic force to the electromagnet through the magnetic field formed by the electromagnetic wire in the electromagnetic seat when power is supplied. The magnetic force is transmitted to the magnetic sleeve through the magnetic ring, so that metal debris in the oil can be adsorbed on the magnetic sleeve when the oil in the cylinder passes through, thereby filtering the metal. The clamp can be removed by tightening the bolts to remove the opening and closing cover, and then the electromagnetic wire can be powered off to easily clean the metal debris collected in the cylinder, thereby collecting the fine metal debris in the oil.

[0020] (3) The present invention connects the filter element in the primary filter cartridge with the injection pipe, and can filter out debris impurities mixed in the oil when the oil passes through, thereby preliminarily filtering the impurities in the oil to prevent the impurities from clogging the hydraulic equipment pipeline.

[0021] (4) The present invention transfers the hydraulic heat in the oil pump housing to the cooling fins of the heat sink through a copper socket. When the motor in the micro blower box is energized, the fan will rotate, so that air with a relatively high outside temperature can be injected into the heat sink from the air inlet pipe. When passing through multiple groups of heat sink fins, the high-temperature air around the fins is heat exchanged. After the heat exchange, the high-temperature air is discharged from the air outlet pipe, thereby achieving heat dissipation for the oil pump and avoiding damage to the equipment caused by high temperature.

[0022] (5) The present invention drives the driving shaft to rotate clockwise through an external motor, and drives the driven gear to rotate through the driving gear, so that the gear teeth of the two sets of gears at the oil inlet end of the oil pump housing are gradually disengaged, the volume is increased to form a local vacuum, and the oil is sucked in, and conversely, the oil outlet end on the other side discharges the oil to achieve oil injection.

[0023] In summary, the present invention has the advantages of high practicality and oil leakage detection. BRIEF DESCRIPTION OF THE DRAWINGS

A set of equipment is connected through the top of the seat 406 with a flow sensor 408, the inside of the detection sphere 401 is movably connected with a movable sleeve rod 409, the top of the movable sleeve rod 409 is installed with a turbine propeller 410, the top of the turbine propeller 410 is installed with a screw nut 411, the inside of the movable sleeve rod 409 is movably connected with a traction screw 412, the top of the detection sphere 401 is connected through the piston cylinder 416, the top of the piston cylinder 416 is installed with a trigger seat 417, the inside of the piston cylinder 416 is movably connected with a trigger piston 418, the top of the trigger piston 418 is provided with a metal push rod 419, the top of the trigger seat 417 is fixedly connected with an assembly plate 420, and the top of the assembly plate 420 is installed with a warning light 421.

[0062] Among them, the metal filter cartridge 501 is a metal filter unit, which can filter the wear debris of the gear structure inside the oil pump and the metal structure inside the detection mechanism 4. The unit enters and exits the liquid through the liquid inlet pipe 502 and the liquid outlet pipe 504, and is connected through the docking end 503, and guides the flow through the two groups of flow guide holes 507 on the flow-blocking inner plate 506; when the electromagnetic wire 510 in the electromagnetic seat 508 is energized, a magnetic field can be formed and magnetic force can be given to the electromagnet 511, and the magnetic force is transmitted to the magnetic sleeve 513 through the magnetic ring 512, so that when the oil in the cartridge passes through, the metal debris in the oil can be adsorbed on the magnetic sleeve 513, thereby achieving metal filtering.

[0064] Among them, the opening and closing cover 514 is sealed and installed with the metal filter cartridge 501 by engaging the engaging pliers 515 with two sets of engaging grooves 516 and tightening the fastening bolts 517 with the upper limit holes 518 of the opening and closing cover 514. This installation method is convenient for users to disassemble and clean the debris collected in the cartridge.

[0065] Working principle:

[0066] The user assembles the oil pump housing 1 and two sets of end plates of the oil pump through the housing bolts 107, and connects the circuit through the connection structures of various mechanisms. During use, the external motor drives the driving shaft 103 to rotate clockwise, and drives the driven gear 105 to rotate through the driving gear 104, so that the gear teeth of the two sets of gears at the oil inlet end of the oil pump housing 1 are gradually disengaged, the volume is increased to form a local vacuum, so that the oil is sucked in, and on the contrary, the oil outlet end on the other side discharges the oil to achieve oil filling;

[0067] The oil is injected into the primary filter cartridge 301 through the injection pipe 302, and the debris and impurities in the oil are filtered out after passing through the filter element 309 in the cartridge. The filtered oil is injected into the detection sphere 401 through the discharge pipe 303, and injected into the metal filter cartridge 501 through the guide end 402 on the detection sphere 401, and finally discharged from the outlet pipe 504 on the cartridge into the hydraulic rod to complete the hydraulic movement;

[0068] When the oil enters the detection sphere 401, the hydraulic pressure and flow rate of the oil at the oil outlet are detected by the hydraulic sensor 407 and the flow sensor 408 on the sphere. When the oil flows, the turbine propeller 410 can drive the movable sleeve rod 409 and the screw nut 411 to rotate on the structural bearing 414, and the connection between the screw nut 411 and the traction screw 412 can drive the traction screw 412 to move upward, so that the traction screw 412 can extend into the piston cylinder 416 to squeeze the trigger piston 418, so that it overcomes the air pressure in the piston cylinder 416 and its own weight to push the metal push rod 419 at the top of the trigger piston 418 into the trigger seat 417, so that the metal push rod 419 and the power supply in the trigger seat 417 are conductive. The half ring 427 contacts the inner convex block 428 on the inner side of the conductive half ring 434 of the equipment, so that the two sets of power conductive half rings 427 are connected, and the power input line 432 further supplies power to the warning light 421, completing the triggering warning of the warning light 421. When the warning occurs, the warning signal can be transmitted to the remote receiving end for reminder through the wireless signal transmitter 425 on the signal control unit 424. Therefore, during the use of the oil pump, when the oil pump does not leak, the hydraulic pressure and rotation speed at the oil outlet end will be sufficient to drive the turbine propeller 410 and trigger the warning light 421. When the oil pump leaks, the hydraulic pressure and rotation speed at the oil outlet end will be insufficient to drive, thereby realizing the leakage detection function of the oil pump through the mechanical triggering method and the use of two sets of sensors;

[0069] When the oil enters the metal filter cartridge 501, the electromagnetic wire 510 in the internal electromagnetic seat 508 can form a magnetic field and impart magnetic force to the electromagnet 511 when it is energized. The magnetic force is transmitted to the magnetic sleeve 513 through the magnetic ring 512, so that the metal debris in the oil can be adsorbed on the magnetic sleeve 513 when the oil in the cartridge passes through, thereby filtering the metal. After use, the user can loosen the fastening bolt 517 and remove the clamp 515 to remove the opening and closing cover 514, and then disconnect the electromagnetic wire 510 to easily clean the metal debris collected in the cartridge;

[0070] During use, the gear structure in the oil pump housing 1 will generate heat due to long-term contact, thereby increasing the temperature of the oil. The heat of the oil in the cavity can be transferred to the heat dissipation fins 203 of the heat dissipation box 202 through the copper fitting seat 201. The motor in the micro blower box 207 is powered on to drive the fan to rotate, so that the air with higher external temperature can be injected into the heat dissipation box 202 from the air inlet pipe 204. When passing through multiple groups of heat dissipation fins 203, the high-temperature air around the fins is heat exchanged. After the heat exchange, the high-temperature air will be discharged from the air outlet pipe 205, thereby realizing the heat dissipation of the oil pump and avoiding damage to the equipment caused by high temperature. Fig.17 The figure shows the plunger and cam structure of a traditional fuel injection pump, which can be arranged at the oil outlet end of the metal filter mechanism 5. The reciprocating drive of the cam can drive the plunger to reciprocate to accurately discharge oil, thereby ensuring the accuracy of oil supply and injection.
