introduction：Touch glass failure repair Anything that touches the finger more is touching the glass，It is the surface layer of the touch screen，In general, this type of failure is mainly caused by the use of personnel who are too rude，Careless transportation is also one of the accidental factors causing damage to the touch screen，However, the problem caused by transportation is generally the problem of touch glass damage，If the touch glass is damaged，Then the touch screen needs to be replaced during maintenance，And the touch screens produced by various manufacturers are not the same，So when it came time to change，There will be a mold opening process，If the mold goes well，Then the maintenance becomes a lot easier，If the mold doesnt go well，Then you need to replace the touch screen。

introduction：For a dry transformer，The so-called balance voltage of the relay，It is the voltage that keeps the relay from operating。It can be done by setting an adjustable resistor in the voltage sensing circuit of the voltage relay，To achieve the purpose of pre-setting balanced voltage。In this way，The voltage value of the adjustable range of the resistor can be preset。 Dry transformers usually need to maintain the remote bus voltage at a fixed level。When the line voltage drop increases due to increased load，A line voltage compensation device consisting of an adjustable resistor and a reactor with tap-tap can be used，Connect the reactor to the secondary side of a current transformer，The current flowing through the primary side of the current transformer is the load current。By appropriate adjustment of resistor and reactor parameters，It depends on the characteristics of the line，It is possible to maintain a constant voltage at a certain point in the system，Without having to consider the load and power factor changes。 Metho

introduction：The first step：The raw edge in the mechanical device needs to be cleaned before the linear guide rail of the transmission parts of the imported device、Contaminants and external scars。 A word of caution here：The linear guide must be coated with a layer of anti-rust oil before the formal installation，Before installation, please use special cleaning oil to clean the base level before installation，Once the anti-rust oil is cleaned，Datum surfaces are prone to rust，Therefore, it is recommended to apply a spindle smooth oil with low viscosity。 Set pace second point：Tighten the positioning screw holes of the guide rail slightly from the center to both sides,Make the track fit to the vertical mounting surface。Secondly, from the beginning of the center position to the two ends to obtain a constant precision state。Vertical datum surface after slightly tightening treatment，Increase the locking force of the lateral datum，Enables the main rail to fully fit the lateral datum position。
