Detailed Product Description: | Guangzhou air shaft maintenance, inspection and analysis of the integrity of the manufacturers] air shaft repair price (1) to understand the situation after the failure to understand the working conditions and symptoms before failure after failure. (2) carefully analyze the reasons or failure to produce the range and find the range of causes of failures or failure analysis. (3) check the appearance, mainly checked fuses, relays, contactors, switches, etc., and stroke fixing screws and terminal screws are loose? Have broken places? There is no money to burn, or contact welding ring phenomenon? Electrical activity organization is flexible? And so on. For obvious faults immediately removed. (4) power with the primary fault is to find implicit. Whether the general use of components and circuit resistance multimeter to check the fault zone files have open, short or ground phenomenon. Sometimes also help shake table and other devices to be checked. If can not find the cause of the failure to check off, you can check the power. (5) power check, mainly to find difficult to find fault. Checks should be energized with no load in order to avoid detection method accidents machine electrical fault detection method is often used mainly voltage method, resistance method, short method, the open method and current method and so on. (1) the voltage value of a point on the line voltage method to determine the use of measuring instruments to determine the scope of the machine component failure or electrical failure point method called voltage or voltage measurement method. (2) a point on the line resistance measurement method using the instrument off or components to determine a method called fault point resistance method. (3) Short-circuit method on the machine with two wires shorted together isoelectric point, to determine the point of failure or malfunction of the scope of the method is called short-circuit method. (4) open method maintenance machine circuit, sometimes in order to detect the special needs must be checked off the circuit, this method is called open method. (5) Method of measuring the current through the current line of a method to determine whether the normal method is called fault current method. [1] electrical machine repair troubleshooting steps can generally be divided into the following steps: (1) preparation of preparatory work, including (2) interpret drawings to be prepared to overhaul the machine tool, instrumentation, circuit diagrams and other information, such as machine tools, we must first understand the circuit diagram. (3) "I asked, watching two or three touch, four, five operations," to clarify the situation before and after the failure of the phenomenon and failure occurs. I asked: To ask the operator to understand the machine before and after the occurrence of a failure; failure is sudden or frequent occurrence? What abnormal phenomenon? What distortions? And so on. Such accurate knowledge of the initial first-hand information, help determine the site of the fault occurred, quickly identify the point of failure. Second Look: the situation carefully observed surface electrical machines or lines. Three: Start the machine and listen to the motor, control transformers, contactors, relays, etc. Are there abnormal sound and closing sound. Four touch: When the machine run for a period of time, turn off the power, hand-molded housing related electrical or electromagnetic coils, check if there is more than normal heat phenomena. Five: From the start starts, all functions operate the machine one by one demonstration, careful observation of the operation in the operation step by step, from discovery tools to find electrical faults, in order to facilitate rapid accurately determine the scope of the machine electrical fault . (4) the approximate range of failure analysis combining circuit diagram from the above, "asked, seeing, hearing, touch, action" after the failure of the process to figure out the basic phenomenon, then you can combine circuit diagram according to the general scope of the analysis of failure symptoms, and then use the appropriate The detection method to identify the point of failure.
