Nine methods for repairing liquid level instruments
1. The direct sensory method is a method of using the direct sensations of the eyes, ears, nose, and hands to stop making judgments. It is a helpful wrist for testing the lack of sensation. All departments, levels, routes, and points can be jointly applied in the process of tightening inspection. When it comes to identifying problems and finding solutions, chance is particularly important.
2. The panel tightening method is an application of the float level gauge panel to hold the internal circuit switches, knobs, sockets, buttons, and other equipment to stop the problem of tightening. Panel tightening is a commonly used external tightening method by panel tightening mages to determine the appearance and level of problems. However, because the panel of the liquid level gauge is completely different from the one used to determine the optimal location for identifying faults, it is necessary to work together with other methods to fully determine the scope of the fault. So, individually speaking, panel tightening mages are an ineffective way to help.
3. Test identification method is a method of identifying the number of stops in measuring circuit data using instruments. It is the most commonly used fundamental method to tighten the problem path and points. The test identification method is divided into two types: power on test and non power on test. Power on testing includes testing of voltage and current related to the level gauge, testing of circuit component parameters, and testing of important technical indicators of the level gauge. The most commonly used tests are voltage and current testing. Non powered testing refers to the testing of the relevant circuits, components, elements, and insulation resistance of the liquid level gauge. By comparing the test data with abnormal data, it is possible to distinguish whether the liquid level gauge has any faults or areas of malfunction. For example, the data reviewed by the ZO zirconia oxygen content analyzer can be compared with our electronic sample data sheet. If it does not comply with the indicated instrument malfunction, there may be various issues such as wiring performance
4. The annoyance tracking method uses a small screwdriver held in hand to gradually fasten each level of electronic components from the final stage of the liquid level gauge forward, while determining the faulty part and level based on the size of the lifting device and the presence or absence of speaker sound. For example, in the process of annoyance tracking, if a certain level of abnormality is discovered and there is no sound or minimal noise when the previous level is reached, then the area between the posterior and anterior levels is the faulty part. Disturbance tracking is a commonly used method for testing magnetic float level gauges, such as UHZ-50 level gauges.
5. The method of using a flag signal tracker (the simplest of which is a detector composed of a semiconductor diode and headphones) to review the fault method of a compact magnetic flip column liquid level gauge. The method is to output a certain signal from the signal generator and add it to the liquid level gauge to be repaired, and use a signal tracker to monitor the signal from the front stage to determine the level of the problem.
6. The signal tracking method uses a signal generator to input audio, intermediate frequency, and high-frequency signal signals to each level of the liquid level gauge in a step-by-step and discriminative manner from back to front. At the same time, the output size and presence of abnormal phenomena obtained from the terminal components are used to review whether the tasks at each level can be deformed and determine the level of the problem.
7. The tracking and tracing method is the fundamental way for the tracking and tracing wizard to inspect the high sensitivity of the magnetic flap level gauge. It includes three methods: disturbance tracking method, signal tracking method, and signal tracking method.
8. Comparative substitution method is a method of comparing and exchanging two types of liquid level gauges, components, devices, and other components with the same example to distinguish between good and bad, abnormal or not, in order to identify compression problems. In the absence of instruments or in situations where the liquid level gauge is unfamiliar, the fundamental method to distinguish between good and bad, and whether it is deformed or not is relatively simple and easy. For example, if a magnetic flowmeter is damaged during operation, it can be compared with a deformed electromagnetic flowmeter to distinguish its advantages and disadvantages. For example, if a certain part (float) of the liquid level gauge is damaged, it can be distinguished by looking at the deformed float of the liquid level gauge. So, it is the fundamental way to identify certain flaws.
9. The mute level cutting method is important for checking the sound, buzzing (exchange sound), and noise of liquid level gauges. The detailed method is to use high-capacity capacitors or short-circuit bars to short-circuit the signal input circuit and signal output circuit of each level gauge step by step from front to back, in order to determine the faulty part and level. If the fault is stable or has little impact when a certain level is short circuited, and the fault dissipates when the next level is short circuited, then the location of the fault is between the rear and front stages and related circuits.
