[0002] Hydraulic oil station is an important component in hydraulic system, which is responsible for storing, cooling and purifying hydraulic oil. Hydraulic oil station usually includes oil tank, cooler, heater, liquid level meter, thermometer, pressure gauge and various valves. The main function of hydraulic oil station is to provide clean and appropriate temperature hydraulic oil for hydraulic system to ensure normal operation of the system.

[0003] Hydraulic oil filtering equipment is a device used in hydraulic oil station to remove impurities in oil. It removes solid particles, water and other contaminants in oil through physical or chemical methods to maintain the cleanliness of oil, prolong the service life of hydraulic components and ensure the stability and reliability of hydraulic system. Hydraulic oil filtering equipment includes filter, filter element, filter screen and other components, which can be installed inside the oil tank or on the hydraulic system circulation loop.

[0004] In actual operation, if the oil filtering efficiency of the hydraulic oil filtering equipment for hydraulic oil station is slow, it will lead to a decrease in equipment use efficiency and affect the normal use of the equipment. Low filtering efficiency means that impurities in the hydraulic system cannot be removed in time, which will slow down the system response and affect the start, stop and speed adjustment of the equipment. Low filtering efficiency requires more frequent replacement of filter elements and hydraulic oil, which increases maintenance cost and labor intensity. Due to slow equipment response and increased failure rate, the efficiency of the entire production line will be affected, resulting in a decrease in production efficiency. UTILITY MODEL CONTENTS

DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, purposes and effects realized by the utility model easy to understand, the utility model is further described below in combination with specific implementation manners.

[0025] As shown in Figure 1 - Figure 4 A hydraulic oil filtering equipment for hydraulic oil station mainly comprises a base 1, a hydraulic oil station body 2, a pump body 3 and an oil tank 4. The hydraulic oil station body 2 and the oil tank 4 are carefully installed on the base 1, and the pump body 3 is ingeniously installed on the hydraulic oil station body 2, thereby ensuring the stability and reliability of the equipment.

[0026] A second valve 6 is designed at the lower end of the oil tank 4, and the outer end of the valve is connected with a second pipeline 14, so as to ensure the smooth flow of the hydraulic oil. Meanwhile, a first valve 5 is arranged at the pump body 3, and the outer end of the first valve 5 is connected with a first pipeline 7, thereby further ensuring the flow control of the hydraulic oil.

[0027] In order to achieve effective filtration of hydraulic oil, we ingeniously set a flow tank 8 between the first pipeline 7 and the second pipeline 14. The inner cavity of the flow tank 8 is installed with a piston 9 in the middle, and the outer end is installed with a hydraulic device 10. The hydraulic device 10 is connected with the piston 9, which can effectively drive the piston 9 to reciprocate in the flow tank 8, thereby driving the flow of hydraulic oil in the flow tank 8.

[0028] The side walls of the flow tank 8 are respectively connected with the first connecting pipe 11 and the second connecting pipe 13, and the filter cartridge 12 is installed between the two connecting pipes. The filter cartridge 12 plays a role in filtering the hydraulic oil through the filter medium inside it, ensuring the cleanliness of the hydraulic oil.

[0029] In order to ensure that the first pipeline 7 and the second pipeline 14 can be reliably connected with the flow tank 8, we set a connecting flange at both ends of them. The first pipeline 7 is connected with the first valve 5 through sealing and fixed connection, and the second pipeline 14 is also connected with the second valve 6 through sealing and fixed connection, thereby ensuring the sealing and reliability of the entire system.

[0030] The piston 9 divides the space in the inner cavity of the flow tank 8 into two independent flow cavities, namely the first flow cavity and the second flow cavity. The first pipeline 7 and the first connecting pipe 11 are connected with the first flow cavity, while the second pipeline 14 and the second connecting pipe 13 are connected with the second flow cavity. This design allows the filter cartridge 12 to be connected with the first pipeline 7 and the second pipeline 14, thereby achieving filtration during the flow of liquid.

[0031] In order to further ensure the sealing of the system, we set a sealing cover at the open end of the flow tank 8. The sealing cover is connected with the flow tank 8 through bolts, and a sealing ring is provided at the connection. The hydraulic device 10 is fixed on the sealing cover through bolts, and the sealing cover and the hydraulic device 10 achieve mechanical sealing, thereby ensuring the sealing performance of the system.

[0032] The function of the hydraulic device 10 is to drive the piston 9 to reciprocate in the flow tank 8, thereby driving the hydraulic oil in the first flow cavity and the second flow cavity to move. This movement speeds up the flow rate of the hydraulic oil, making it smoothly enter the filter cartridge 12 for filtration.

[0033] In addition, the first connecting pipe 11 and the second connecting pipe 13 are connected with the cover of the filter cartridge 12, and a sealing ring is also provided at the connection between the cover and the connecting pipe to ensure the sealing of the connection. Control valves are also provided on the first connecting pipe 11 and the second connecting pipe 13, which can be used to adjust the flow of hydraulic oil to meet different filtration needs.

[0034] Assembly process: Install the hydraulic oil station body 2 and the oil tank 4 on the base 1. Install the pump body 3 on the hydraulic oil station body 2. Connect the first valve 5 to the pump body 3 and the first pipe 7 to the first valve 5. Connect the second valve 6 to the oil tank 4 and the second pipe 14 to the second valve 6. Install the flow tank 8 in place and install the piston 9 in it. Connect the hydraulic device 10 to the piston 9. Connect the first adapter pipe 11 and the second adapter pipe 13 to the two ends of the flow tank 8 respectively. Install the filter cartridge 12 between the first adapter pipe 11 and the second adapter pipe 13. Install the sealing ring at all pipe and tank body connections. Secure the sealing cover to the flow tank 8 with bolts and ensure mechanical sealing with the hydraulic device 10. Install control valves on the first adapter pipe 11 and the second adapter pipe 13 for adjusting the flow rate of hydraulic oil.

[0035] The use process is as follows: open the first valve 5 and the second valve 6 to ensure that the hydraulic oil can flow freely. Start the hydraulic device 10 to make the piston 9 reciprocate in the flow tank 8. Adjust the control valves on the first adapter pipe 11 and the second adapter pipe 13 as needed to control the flow rate of hydraulic oil. Hydraulic oil enters the first flow cavity of the flow tank 8 through the first pipe 7, and the reciprocating movement of the piston 9 drives the hydraulic oil to flow in the flow tank 8. The hydraulic oil is filtered by the filter cartridge 12 to remove impurities. The filtered hydraulic oil flows into the oil tank 4 through the second flow cavity and the second pipe 14. Check the filter cartridge 12 regularly and replace the filter medium if necessary. Ensure that there is no leakage at all connections and sealing rings to maintain the sealing and reliability of the system. After filtration is completed, close the first valve 5 and the second valve 6. Stop the hydraulic device 10 to stop the movement of the piston 9. Close the control valves to ensure that the system is in a static state.
