[0002] Hydraulic machinery, especially hydraulic presses, is a machine that uses liquid as the working medium and is made according to Pascal's principle to transfer energy to achieve various processes. The working principle of hydraulic machinery is based on Pascal's law, that is, the pressure is equal everywhere in a closed liquid. The hydraulic oil is delivered to the integrated cartridge valve block by the oil pump, and then distributed to the upper or lower chamber of the oil cylinder by various check valves and relief valves. Under the action of high pressure oil, the oil cylinder moves, thereby transferring and converting energy.
[0003] During the operation of hydraulic machinery, various impurities inevitably arise or are introduced into the hydraulic system. If these impurities are mixed into the hydraulic oil, they will cause damage as the hydraulic oil circulates, seriously affecting the normal operation of the hydraulic system. Existing hydraulic machinery is not convenient for removing these impurities and foreign objects. Therefore, this application provides a hydraulic machinery with foreign object removal and preheating functions to meet the needs. Utility Model Content

An oil tank 9 is fixed to one side of a fixed plate 8. Heating rods 10 are installed on both sides of the upper part of the oil tank 9. The heating rods 10 are symmetrically arranged around the central axis of the oil tank 9. The heating rods 10 installed inside the oil tank 9 can heat the hydraulic oil during the process of entering and exiting the equipment, effectively increasing the temperature of the hydraulic oil and reducing its viscosity, thereby improving the fluidity of the hydraulic oil and improving the operating efficiency of the hydraulic equipment. Oil pumps 11 are installed on both sides of the oil tank 9. An oil delivery pipe 12 is installed on one side of the oil pump 11, and a filter mechanism 13 is installed on one side of the oil delivery pipe 12.
[0023] Please see Figure 4-5The filtration mechanism 13 includes a filter cylinder 1301, a sealing cover 1302, a connecting pipe 1303, a sealing ring 1304, a filter element 1305, a fixing plate 1306, and a fixing bolt 1307. The filter cylinder 1301 is fixed to one end of the oil supply pipe 12. The sealing cover 1302 is installed on the top of the filter cylinder 1301, and the connecting pipe 1303 is fixed on the top of the sealing cover 1302. One end of the connecting pipe 1303 is connected to the oil inlet 4, and the bottom of the connecting pipe 1303 is connected to the top of the filter element 1305. The hydraulic oil is filtered by the filter element 1305, which blocks impurities and foreign objects, thereby effectively removing impurities and foreign objects from the hydraulic oil, preventing them from causing wear or blockage inside the hydraulic machinery, maintaining the cleanliness of the hydraulic oil, and thus extending the service life of the hydraulic machinery. For extended service life, a sealing ring 1304 is fitted inside the lower part of the sealing cover 1302. The sealing ring 1304 is made of NBR nitrile rubber and fits tightly against the lower inner side of the sealing cover 1302. The sealing ring 1304 can effectively prevent hydraulic oil leakage and ensure the sealing performance of the filter cartridge 1301. The filter element 1305 is installed below the sealing cover 1302. Fixing plates 1306 are fixed on both sides of the sealing cover 1302. Fixing bolts 1307 pass through the top of the fixing plates 1306. The sealing cover 1302 is threadedly connected to the filter cartridge 1301 through the fixing bolts 1307.

[0024] Working principle: When using this hydraulic machinery with foreign object removal and preheating functions, first connect the external power supply, then add hydraulic oil to the oil tank 9. When the hydraulic machinery is in use, the heating rod 10 can be turned on to increase the temperature of the hydraulic oil and reduce its viscosity, thereby improving the fluidity of the hydraulic oil. Then, the hydraulic oil is pumped by the oil pump 11. After the hydraulic oil enters the filter cartridge 1301, it is filtered by the filter element 1305, which blocks and filters impurities and foreign objects, thereby effectively removing impurities and foreign objects from the hydraulic oil and preventing them from causing wear or blockage inside the hydraulic machinery, thus maintaining the cleanliness of the hydraulic oil. When the device is not in use, disconnect the external power supply. In this way, the use of the hydraulic machinery with foreign object removal and preheating functions is completed.
