Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic stations, and in particular relates to an automatic temperature control system for a hydraulic station. Background Art

[0002] In the cold-rolled stainless steel production process, the hydraulic station automatic temperature control system usually uses a temperature sensor to monitor the temperature of the hydraulic oil. In traditional technology, the method of setting the temperature sensor in the hydraulic oil tank of the hydraulic station to monitor the oil temperature is simple and convenient;

[0003] However, since the temperature sensor is set in the oil tank, it monitors the average temperature of the hydraulic oil in the tank. Such a setting may have a certain lag for the entire hydraulic system, especially when the temperature distribution of the hydraulic system is uneven, the temperature in the oil tank may not accurately reflect the actual situation of each part of the system. Setting the temperature sensor only in the oil tank cannot accurately control the temperature of the hydraulic oil when it enters and leaves the hydraulic system. This may cause the temperature of the hydraulic oil to exceed the most suitable working range when entering or leaving the system, affecting the performance and life of the system. Since the sensor is set in the oil tank, the temperature change it detects may not be as timely as the sensor set at the inlet and outlet of the hydraulic oil. This may cause the system to be unable to make timely adjustments when the temperature is abnormal, which may cause overheating or overcooling of the equipment.

[0004] Therefore, in order to more effectively monitor and control the temperature of the hydraulic oil and ensure the stable operation of the hydraulic system, it is necessary to design an automatic temperature control system with temperature sensors installed at the inlet and outlet of the hydraulic oil. Utility Model Content

[0005] In order to make up for the deficiencies of the prior art, the utility model proposes an automatic temperature control system for a hydraulic station.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] An automatic temperature control system for a hydraulic station, comprising an air-cooled radiator for dissipating heat from hydraulic oil, an oil inlet pipe and an oil outlet pipe connecting the air-cooled radiator and the hydraulic station, a controller, a temperature sensor A, a temperature sensor B and an alarm;

[0008] Temperature sensor A is installed at the oil inlet pipe and the oil inlet of the air-cooled radiator and monitors the temperature of the hydraulic oil coming out of the hydraulic station in real time. Temperature sensor B is installed at the oil outlet pipe and the oil outlet of the air-cooled radiator and monitors the temperature of the oil after the oil is cooled by the air-cooled radiator in real time.

[0009] Temperature sensor A and temperature sensor B transmit the monitored oil temperature data to the controller. When it is detected that the temperature of the hydraulic oil exceeds the preset threshold, the controller will control the alarm to sound an alarm to remind the operator to deal with it in time.

[0010] Preferably, a guide block with a guide channel is provided between the oil inlet pipe and the oil inlet of the air-cooled radiator, and between the oil outlet pipe and the oil outlet of the air-cooled radiator, a mounting block with a concave groove is provided on the top of the guide block, the mounting seat of the temperature sensor A or the temperature sensor B is installed on the mounting block, and the temperature probes of the temperature sensor A and the temperature sensor B are both extended into the guide channel of the guide block.

[0011] Preferably, a sealing gasket is provided between the mounting block and the mounting seat, which helps to prevent leakage of hydraulic oil and protect the temperature sensor from contamination and damage, thereby extending the service life of the temperature sensor.

[0012] As a preferred embodiment, both sides of the guide block on which the temperature sensor A is installed are connected to the oil inlet pipe and the oil inlet of the air-cooled radiator through oil pipe joints respectively;

[0013] Both sides of the guide block on which the temperature sensor B is installed are also connected to the oil outlet pipe and the oil outlet of the air-cooled radiator through oil pipe joints.

[0014] Preferably, the air-cooled radiator includes a radiator assembly, a main frame for supporting the radiator assembly, and a fan on the main frame. The radiator pipes on the radiator assembly are respectively connected to the oil inlet and the oil outlet.

[0015] Preferably, an air guide cover is provided between the main frame and the fan to allow the wind flow to evenly cover the fins of the radiator assembly.

[0016] Compared with the prior art, the technical effects and advantages of the utility model are:

[0017] The automatic temperature control system of the hydraulic station ensures the normal operation of the hydraulic system by monitoring and adjusting the temperature of the hydraulic oil. The core of the system is a closed control system consisting of an air-cooled radiator, a temperature sensor, a controller, and an alarm. The temperature sensor monitors the temperature of the hydraulic oil entering and leaving the air-cooled radiator in real time. The controller adjusts the heat dissipation effect of the air-cooled radiator based on the monitoring data to maintain the oil temperature within an appropriate range. If the oil temperature exceeds the set threshold, the controller will activate the alarm to prompt the operator to intervene.

[0018] By precisely controlling the temperature of the hydraulic oil, the system can avoid the degradation of hydraulic oil performance caused by excessively high or low oil temperature, ensuring that hydraulic components such as pumps, motors and valves can work properly. Keeping the hydraulic oil within the optimal temperature range can reduce the aging and degradation of the hydraulic oil, thereby extending the service life of the hydraulic components. The automatic alarm system can issue an alarm in time when the oil temperature rises abnormally, preventing equipment damage and ensuring operator and production safety. The system can monitor the oil temperature in real time and respond quickly to temperature changes to ensure that the performance of the hydraulic oil is always in the best condition.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The following is combined with Figure 1-5 To further explain this application in detail,

[0027] The embodiment of the present application discloses an automatic temperature control system for a hydraulic station, including an air-cooled radiator 1 for dissipating heat from hydraulic oil, an oil inlet pipe 2 and an oil outlet pipe 3 connecting the air-cooled radiator 1 and the hydraulic station, a controller 4, a temperature sensor A5, a temperature sensor B6 and an alarm 7;

[0028] The temperature sensor A5 is arranged between the oil inlet pipe 2 and the oil inlet port 8 of the air-cooled radiator 1 and monitors the temperature of the hydraulic oil coming out of the hydraulic station in real time. The temperature sensor B6 is arranged between the oil outlet pipe 3 and the oil outlet port 9 of the air-cooled radiator 1 and monitors the temperature of the oil after the oil is cooled by the air-cooled radiator 1 in real time.

[0029] The temperature sensor A5 and the temperature sensor B6 transmit the monitored oil temperature data to the controller 4. When it is detected that the temperature of the hydraulic oil exceeds the preset threshold, the controller 4 will control the alarm 7 to sound an alarm to remind the operator to deal with it in time.

[0030] The air-cooled radiator 1 is used to dissipate heat from the hydraulic oil, and the heat of the hydraulic oil is taken away by air flow. The oil inlet pipe 2 connects the hydraulic station and the air-cooled radiator 1, and is used to transport the hydraulic oil to the air-cooled radiator 1 for cooling. The oil outlet pipe 3 connects the air-cooled radiator 1 and the hydraulic station, and is used to transport the cooled hydraulic oil back to the hydraulic station. The temperature sensor A5 and the temperature sensor B6 are arranged near the air-cooled radiator 1, and are used to monitor the temperature of the hydraulic oil in real time. When it is detected that the temperature of the hydraulic oil exceeds the preset threshold, the alarm 7 is triggered to sound an alarm.

[0031] Compared with the traditional technology of only setting a temperature sensor in the hydraulic oil tank, by setting temperature sensors at the inlet and outlet of the hydraulic oil, the temperature of the hydraulic oil before entering the air-cooled radiator 1 and the temperature after heat dissipation can be more accurately monitored, so that the temperature of the hydraulic oil can be more accurately controlled to ensure the normal operation of the system. In the traditional method, the temperature sensor is in the hydraulic oil tank, and the temperature of the hydraulic oil tank may be affected by the temperature distribution of the entire hydraulic system, and the response time may be slow. Setting sensors at the inlet and outlet can detect changes in the hydraulic oil temperature more quickly and adjust the system working state in time.

[0032] The automatic temperature control system can sound an alarm when the hydraulic oil temperature exceeds the preset threshold, which helps to detect potential system problems in time, so as to carry out preventive maintenance and avoid possible equipment failures and production interruptions. By real-time monitoring and controlling the temperature of the hydraulic oil, it can ensure that the hydraulic oil works within the optimal temperature range, thereby improving the efficiency and stability of the entire hydraulic system. When the hydraulic oil temperature is abnormal, the system's automatic alarm function can notify the operator in time to avoid equipment damage caused by excessively high or low oil temperature, ensuring the safety of operators and equipment. The automatic temperature control system is usually centrally managed through the controller 4, which is easy to maintain and adjust.

[0033] A guide block 10 with a guide channel is provided between the oil inlet pipe 2 and the oil inlet 8 of the air-cooled radiator 1, and between the oil outlet pipe 3 and the oil outlet 9 of the air-cooled radiator 1. A mounting block 12 with a concave groove 11 is provided on the top of the guide block 10. The mounting seat 13 of the temperature sensor A5 or the temperature sensor B6 is installed on the mounting block 12, and the temperature probes of the temperature sensor A5 and the temperature sensor B6 are both extended into the guide channel of the guide block 10.

[0034] By arranging a guide block 10 with a guide channel between the oil inlet pipe 2 and the oil inlet port 8 of the air-cooled radiator 1 and between the oil outlet pipe 3 and the oil outlet port 9 of the air-cooled radiator 1, the temperature probes of the temperature sensor A5 and the temperature sensor B6 can be directly extended into the guide channel of the guide block 10. Such a design can ensure that the temperature sensor is close to the flow path of the hydraulic oil, thereby more accurately monitoring the real-time temperature of the hydraulic oil and avoiding the temperature gradient and hysteresis caused by the flow of oil.

[0035] A mounting block 12 with a concave groove 11 is provided on the top of the guide block 10, and a mounting seat 13 of the temperature sensor can be securely mounted on the mounting block 12, which helps ensure the stability of the temperature sensor when the hydraulic oil flows and reduces displacement or damage of the sensor due to vibration or impact.

[0036] A sealing gasket 14 is provided between the mounting block 12 and the mounting seat 13 .

[0037] Helps prevent hydraulic oil leaks while protecting the temperature sensor from contamination and damage, extending the life of the temperature sensor.

[0038] Both sides of the guide block 10 on which the temperature sensor A5 is installed are connected to the oil inlet pipe 2 and the oil inlet port 8 of the air-cooled radiator 1 through the oil pipe joint 15 respectively;

[0039] Both sides of the guide block 10 on which the temperature sensor B6 is installed are also connected to the oil outlet pipe 3 and the oil outlet 9 of the air-cooled radiator 1 through the oil pipe joints 15 respectively.

[0040] Such a design simplifies the connection of the system, facilitates installation and maintenance, and also reduces the connection points where leakage may occur. By combining the installation of the temperature sensor with the design of the guide block 10, the integration of the system can be improved, making the entire automatic temperature control system more compact and efficient.

[0041] The air-cooled radiator 1 includes a radiator assembly 19, a main frame 16 for supporting the radiator assembly 19, and a fan 17 on the main frame 16. The radiator pipelines on the radiator assembly 19 are respectively connected to the oil inlet 8 and the oil outlet 9.

[0042] The air-cooled radiator 1 exchanges heat through the radiator assembly 19 and the heat sink, and uses the wind direction generated by the fan 17 to cool the hydraulic oil. This design can quickly reduce the temperature of the hydraulic oil within a short distance and improve the heat dissipation efficiency. The main frame 16 is used to support the radiator assembly 19 and the fan 17, so that the entire radiator system has a compact structure, saves space, and is easy to install and maintain. The separate design of the radiator assembly 19 and the fan 17 makes maintenance more convenient. The radiator assembly 19 or the fan 17 can be replaced or cleaned separately without the need for overall disassembly. The main frame 16 provides protection for the fan 17, preventing hydraulic oil or other foreign matter from directly contacting the fan 17, and reducing the possibility of failure.

[0043] An air guide hood 18 is disposed between the main frame 16 and the fan 17 to allow the wind flow to evenly cover the heat sinks of the heat sink assembly 19 .

[0044] The air guide cover 18 can make the wind flow evenly cover the cooling fins of the radiator assembly 19, ensuring that the hydraulic oil can be evenly cooled, further improving the heat dissipation efficiency.

[0045] During the cold-rolled stainless steel production process, the hydraulic station oil tank temperature is between 28-50℃. This range is obtained through extensive application practice and hydraulic oil performance testing, which can ensure the best working performance of the hydraulic oil and the stable operation of the system. Within this temperature range, the viscosity of the hydraulic oil is appropriate, which can ensure the normal operation of hydraulic components such as pumps, motors and valves, and also prevent the aging and degradation of the oil.

[0046] The viscosity of hydraulic oil increases at low temperatures, resulting in poor fluidity, which will increase the starting resistance of the system, reduce work efficiency, and may cause the oil pump to fail to suck up oil. Therefore, a heater is configured in the mailbox to heat the hydraulic oil. Heating the hydraulic oil can reduce its viscosity and restore its fluidity, ensuring that the system can start and run smoothly. Appropriate temperature can improve the sealing performance of hydraulic oil and reduce the risk of leakage. Keeping the hydraulic oil within the appropriate temperature range can ensure its good lubrication performance and reduce component wear. Heated hydraulic oil can make the control system respond more quickly and improve the accuracy and stability of operation.

[0047] The oil temperature control system equipped in the hydraulic station also adjusts the oil temperature in the oil tank through the cooler to keep the oil temperature within the optimal working range. Such a system can ensure the quality of the hydraulic oil, extend the service life of the hydraulic components, and improve the performance of the entire hydraulic system.

[0048] The automatic temperature control system of the hydraulic station adjusts the oil temperature in the oil tank through the air-cooled radiator 1. When the oil temperature is higher than the set threshold of 50°C, the controller 4 will start the fan 17 to dissipate heat to reduce the temperature. Once the temperature drops below the set value, the system will turn off the fan 17. If the oil temperature rises to a safety critical point above 50 degrees, the controller 4 will automatically alarm the pneumatic alarm 7, and the automatic alarm system will be triggered to notify the operator to take measures to prevent equipment damage or ensure production safety.

[0049] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
