mechanical oil pressure gauge
Mechanical oil pressure gauge divide into two kinds of automobile oil gauge: pointer type and digital type. The oil gauge is used to indicate the amount of oil in the automobile oil tank. The oil gauge is composed of a oil level indicator with a pressure regulator and a oil level height sensor. The function of the low oil level alarm device is to light up the alarm immediately when the amount of oil in the oil tank is less than a specified value, so as to attract the driver's attention.
The causes of oil gauge failure are as follows:
1.The problem of oil gauge itself: the failure of oil gauge itself will lead to the immobility or misalignment of oil gauge. It can be judged that the pointer of oil gauge still does not swing when the ignition switch is on for about half a minute, or the pointer swings disorderly and the measurement of oil gauge pointer is inaccurate, indicating that the oil gauge is faulty;
2.Sensor failure: when the sensor fails, it will also cause the oil gauge to stop moving. The judgment method is to clamp the multimeter probe on the two wiring posts of the variable resistor of the oil sensor, and use gear R1 to detect the resistance value of the variable resistor. If the result is inconsistent with the standard, the sensor fails;
3.Instrument coil short circuit: instrument coil short circuit will also cause problems in the oil gauge. The simple judgment method is to use a multimeter to measure the voltage.
There are also some special contact type, remote transmission type, etc. From the installation structure type, there are indirect installation, embedded installation and protruding installation. Among them, indirect installation can be divided into radial installation and axial installation. Among them, radial installation is the most fundamental installation method. This installation method is used when the customer does not know. The embedded type and convex type can also be divided into radial type and axial type. The axial installation mainly considers the fluctuation supported by the oil pressure gauge. This installation mode is generally only selected on the pressure gauge with a diameter of less than 150 mm. Various models of oil pressure gauge are available, and the type distribution is also very detailed. Due to the continuous development of technology, the oil pressure gauge has high compressive strength in the process of industrial production and manufacturing to measure accuracy. Because of its irreplaceable role, the oil pressure gauge has been more and more widely used, and it is safer and faster in the process of use. Welcome to ask us
