Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for bearing ring processing, in particular to an intelligent temperature-controlled hydraulic oil circulating cooling supply system. Background Technique

[0002] As the core component of a bearing, the processing accuracy and surface quality of a bearing ring directly affect the overall performance and service life of the bearing. In the production process of bearing rings, a ring rolling machine plays a crucial role. The hydraulic system is the power source of the ring rolling machine, and its stability and reliability directly affect the operation efficiency and processing quality of the equipment.

[0003] In a traditional hydraulic system, problems such as too high oil temperature and deteriorated oil quality are likely to occur under high-temperature and high-pressure environments, resulting in increased wear of hydraulic components and frequent failures. In addition, tiny particulate matters in the hydraulic system will also exacerbate the wear and blockage of components, affecting the normal operation of the hydraulic system. These problems not only increase the maintenance cost of the equipment but also reduce the production efficiency and processing quality.

[0004] Therefore, an intelligent temperature-controlled hydraulic oil circulating cooling supply system is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide an intelligent temperature-controlled hydraulic oil circulating cooling supply system to solve the technical problems that in a traditional hydraulic system, the oil temperature is too high and the oil quality deteriorates under high-temperature and high-pressure environments, resulting in wear and blockage of hydraulic components and affecting the hydraulic system.

[0006] To achieve the above purpose, the utility model provides the following technical solution: an intelligent temperature-controlled hydraulic oil circulating cooling supply system, including a hydraulic oil tank, a circulating pump, a filter, and a first heat exchanger. A hydraulic oil return port is arranged at the top of the hydraulic oil tank. The circulating pump is arranged on one side of the hydraulic oil tank. The inlet of the circulating pump is communicated with the inside of the hydraulic oil tank. The outlet of the circulating pump is communicated with the inlet of the first heat exchanger through the filter. The hydraulic oil supply port of the first heat exchanger returns oil to the hydraulic equipment through a pipeline.

[0007] As a further solution of the utility model, a temperature sensor is installed at the hydraulic oil supply port.

[0008] As a further solution of the utility model, a temperature control valve is installed at the cooling water inlet of the first heat exchanger.

[0009] As a further solution of the utility model, a second heat exchanger is arranged inside the hydraulic oil tank. For the second heat exchanger, both the cooling water inlet and the cooling water outlet are arranged outside one side of the hydraulic oil tank.

[0010] As a further solution of the present utility model, a sedimentation hopper is installed at the lower end inside the hydraulic oil sump. The sewage outlet of the sedimentation hopper is communicated with a sewage pipe, and a sewage valve is installed on the sewage pipe.

[0011] As a further solution of the present utility model, the outlet of the sewage pipe is connected to the inlet of the filtering device through an oil pollution pump.

[0012] Compared with the prior art, the beneficial effects of an intelligent temperature-controlled hydraulic oil circulation cooling supply system of the present utility model are as follows:

[0013] By installing a temperature sensor at the hydraulic oil supply port, the system can monitor the temperature of the hydraulic oil in real time. Combined with the application of a temperature control valve at the cooling water inlet of the first heat exchanger, the system can automatically adjust the cooling water flow rate to achieve precise control of the hydraulic oil temperature. This intelligent temperature control mechanism ensures that the hydraulic equipment operates at the optimal working temperature, extends the equipment life, and improves the working efficiency.

[0014] A circulation pump is used to drive the flow of the hydraulic oil. The hydraulic oil is preliminarily filtered by a filter to remove impurities and particulate matters, ensuring the cleanliness of the hydraulic oil. The hydraulic oil enters the first heat exchanger for cooling, effectively reducing the oil temperature and preventing oil deterioration and equipment failures caused by excessive oil temperature. This combination of efficient cooling and filtration ensures the stable operation of the hydraulic system.

[0015] A second heat exchanger is arranged inside the hydraulic oil sump to form a double heat exchange mechanism with the first heat exchanger. The present utility model not only improves the cooling efficiency but also further reduces the oil temperature when the hydraulic oil flows back to the hydraulic oil sump, providing more suitable oil temperature conditions for the next cycle. At the same time, the double heat exchange also enhances the redundancy and reliability of the system, ensuring stable operation under different working conditions.

[0016] A sedimentation hopper is arranged inside the hydraulic oil sump to collect and precipitate impurities and sediments in the hydraulic oil. Through the design of the sewage pipe and the sewage valve, these impurities can be conveniently discharged, reducing the maintenance workload. In addition, the system also has an interface connected to the first filtering device, and the discharged oil pollution can be further processed through the first oil pollution pump, realizing the recycling of resources and environmental protection.

[0025] Please refer to Figures 1 to 3As shown in the figure, an intelligent temperature-controlled hydraulic oil circulation cooling supply system according to an embodiment of the present invention includes a hydraulic oil tank 201, a circulation pump 202, a filter 203, and a first heat exchanger 204. A hydraulic oil return port 2012 is provided at the top of the hydraulic oil tank 201. The circulation pump 202 is arranged on one side of the hydraulic oil tank 201. The inlet of the circulation pump 202 is communicated with the inside of the hydraulic oil tank 201. The outlet of the circulation pump 202 is communicated with the inlet of the first heat exchanger 204 through the filter 203. The hydraulic oil supply port 2042 of the first heat exchanger 204 returns to the hydraulic equipment through a pipeline. A temperature control valve 20411 is installed at the cooling water inlet 2041 of the first heat exchanger 204. The temperature control valve 20411 is electrically connected to the controller. When the temperature of the returned hydraulic oil is too high, the hydraulic oil is quickly cooled. A second heat exchanger 205 is arranged inside the hydraulic oil tank 201. For the second heat exchanger 205, both the cooling water inlet and the cooling water outlet of the second heat exchanger 205 are arranged outside one side of the hydraulic oil tank 201.

[0026] Specifically, a sedimentation hopper 2011 is installed at the lower end inside the hydraulic oil tank 201. A sewage discharge port of the sedimentation hopper 2011 is communicated with a sewage discharge pipe 20111. A sewage discharge valve 20112 is installed on the sewage discharge pipe 20111. The outlet of the sewage discharge pipe 20111 is communicated with the inlet of the filtering device through an oil pollution pump.

[0027] In the embodiment of the present invention, a temperature sensor is installed at the hydraulic oil supply port 2042. The temperature of the hydraulic oil pumped out from the hydraulic oil supply port 2042 can be monitored in real time through the installed temperature sensor. When the temperature of the hydraulic oil pumped out from the pressure oil supply port 2042 is lower than the set temperature, at this time, the controller will control the temperature control valve 20411 to reduce the opening degree. When the temperature of the hydraulic oil pumped out from the pressure oil supply port 2042 is higher than the set temperature, at this time, the controller will control the temperature control valve 20411 to increase the opening degree, so as to ensure that the temperature of the hydraulic oil pumped out from the hydraulic oil supply port 2042 remains within the set threshold. The temperature sensor adopts a temperature sensor with a model of PT1000, and the controller adopts a PLC controller of the Siemens S7-400 series.

[0028] By adopting the above technical solution, the hydraulic oil returned to the hydraulic oil tank 201 can be pumped into the filter 203 by the circulation pump 202 for filtration. The filtered hydraulic oil is cooled by the first heat exchanger 204 to ensure that the temperature of the hydraulic oil reaches the set temperature range. At the same time, the cooling capacity is adjusted by the temperature control valve 20411 according to the oil temperature of the hydraulic oil to ensure the stability and reliability of the hydraulic system. The sedimentation hopper 2011 can remove tiny particles in the hydraulic oil to ensure the cleanliness of the oil quality. The sewage discharge pipe 20111 can pump the oil pollution impurities in the sedimentation hopper 2011 into the first filtering device through the first oil pollution pump for fine filtration. The filtered hydraulic oil can be re-introduced into the hydraulic oil tank 201 for recycling.
