Description

Technical Field

[0001] This utility model relates to the field of industrial automation technology, specifically to an oil-water mixing signal device. Background Technology

[0002] In industrial sectors such as hydropower stations, thermal power plants, and large pumping stations, the stable operation of oil systems is crucial to the overall performance and safety of generator sets. Oil systems typically contain a large amount of lubricating oil, which plays a key role in lubrication, cooling, and sealing during equipment operation. However, due to the complex operating environment, water often gets mixed into the oil tank or oil pipelines, posing a potential threat to the normal operation of the oil system. When water mixes with the oil, it significantly affects the physical and chemical properties of the oil, such as viscosity, lubrication performance, and oxidation stability. Water reduces the viscosity of the oil, making it unable to effectively form a lubricating film between friction parts, thereby aggravating the wear and damage of the parts. In addition, water also accelerates the oxidation process of the oil, leading to oil quality deterioration and further affecting the performance and lifespan of the equipment.

[0003] Traditional methods for monitoring water content in oil mainly rely on manual observation of the oil's color and viscosity, and on the operator's experience to determine whether the oil contains water and the proportion of water. However, this method is highly subjective and uncertain, and cannot provide accurate measurement values. Due to the poor real-time and continuous nature of manual monitoring, it is often impossible to detect and deal with the problem of excessive water content in the oil in a timely manner, thus posing a threat to the safe operation of equipment. To address this, we propose an oil-water mixing signal device. Utility Model Content

By employing highly conductive, corrosion-resistant, and high-strength materials as temperature sensing elements, and incorporating built-in precision sensing elements, this device can accurately and in real time detect changes in the water content of oil. This high-precision monitoring capability helps to promptly identify oil quality problems and prevent equipment malfunctions or damage caused by excessive water content. The built-in microcontroller can filter, amplify, and digitize the captured electrical signals to obtain accurate water content values. These values ​​are converted into standard analog signals for easy communication and display with other devices.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-3 An oil-water mixing signal device includes a protective housing 1, characterized in that: a detection head 2 for detection is fixedly installed at the lower end of the protective housing 1; a fixing member 3 for fixing is fixedly installed at the connection between the upper end of the detection head 2 and the protective housing 1; and an external cable 5 for connecting is fixedly installed at the side end of the protective housing 1. A sensor 6 for control is sleeved inside the protective housing 1. The oil-water mixing signal detection head 2 is inserted into the oil tank or oil pipeline. The instrument chip converts the detection by the detection head 2 and displays the value in real time through the LED display screen 7, which also has adjustable switch output, 4-20mA analog output, and RS485 communication output.

[0024] Furthermore, the lower end of the fixing part 3 is provided with an external thread 4, and a fixing nut is sleeved on the surface of the external thread 4. The outer end of the external thread 4 is threadedly connected to the external mounting structure. The corresponding thread is machined at the appropriate position of the installation in the oil tank. The position of the signal device is adjusted to ensure that the effective measurement range of the probe 2 is completely submerged in the oil. The signal device can be fixed by tightening the thread.

[0025] Furthermore, a sealing ring is provided at the bottom of the surface of the fastener 3, and the sealing ring cooperates with the fixing nut.

[0026] Furthermore, the upper surface of the probe 2 is provided with an external thread 4, and the internal circuit of the probe 2 is connected to the internal circuit of the sensor 6. The probe 2 detects the oil pipe through the built-in sensing element, and the detected signal is transmitted to the microcontroller inside the sensor 6.

[0027] Furthermore, the external cable 5 is fixedly installed on the side of the protective housing 1. The front end of the external cable 5 is electrically connected to the power supply. The working power supply of the sensor 6 is a common power supply. When the detected moisture content exceeds the preset alarm value, the signal device will issue an alarm signal. This is usually achieved through the output of the external cable contact, which can drive the audible and visual alarm or other indicator devices.

[0028] Furthermore, an LED display screen 7 is installed on one end of the sensor 6, and three adjustment buttons 8 for control are installed at the lower end of the LED display screen 7. The LED display screen 7 and the adjustment buttons 8 are connected to the internal wiring of the sensor 6. An ARM series microcontroller is embedded in the sensor 6. The signal device displays the moisture content value on the LED display screen 7, which is convenient for the on-duty personnel to view and monitor in real time. Multiple adjustment buttons 8 are installed at the lower end of the LED display screen 7. Users can press these buttons to set the alarm parameters of the equipment.

[0029] Furthermore, the connection between sensor 6 and LED display 7 uses a shielded cable.

[0030] Working Principle: The core component of the device is the probe head 2, which typically uses a material with good conductivity, corrosion resistance, and strength as its temperature sensing element. The probe head 2 detects the water content in the oil through its built-in sensing elements. These sensing elements are designed to be inserted into the oil tank or oil pipeline to sense the capacitance of the surrounding environment in real time. When water mixes into the oil, the difference in dielectric constant between water molecules and oil molecules changes the capacitance value around the sensor. This change is captured by the sensor and converted into an electrical signal. The captured electrical signal is converted and processed by the microcontroller inside the sensor 6. The microcontroller uses advanced algorithms to filter, amplify, and digitize the signal to obtain an accurate water content value. These values ​​are then converted into standard analog signals (4-20mA current signals) for communication and display with other devices. When the detected water content exceeds a preset alarm value, the signal... The signal transmitter will emit an alarm signal, which is usually achieved through an external cable connection output. It can drive an audible and visual alarm or other indicating devices. At the same time, the signal transmitter can also display the water content value on the LED display screen 7 for the convenience of the duty personnel to view and monitor in real time. There are multiple adjustment buttons 8 at the bottom of the LED display screen 7. Users can press these buttons to set the alarm parameters of the equipment. If the user needs to reset, they need to take a bottle of oil containing the corresponding percentage of water, mix the oil and water, insert the signal transmitter into the oil, and adjust the SET potentiometer until AL just lights up. The alarm value is then set. When the water ratio reaches the set value, the signal transmitter will alarm. An external thread 4 is provided at the bottom of the fixing part 3. The corresponding thread is machined at the appropriate position of the installation in the oil tank. The position of the signal transmitter is adjusted to ensure that the effective measurement range of the probe 2 is completely submerged in the oil. The thread is then tightened.
