introduction：One video signal corresponds to a monitor or video recorder，If you want to send the image of one camera to multiple managers，The video splitter is recommended，Because the parallel video signal attenuation is large，After sending to multiple output devices due to impedance mismatch and other reasons，The image will be badly distorted，The lines are also unstable

introduction：Schematic diagram of current relay A current relay is an electronic control device，It has a control system and a controlled system，It is usually used in automatic control circuits，It actually uses a smaller current to control a larger current“Automatic switch”。Therefore, it plays an automatic regulation in the circuit、Security protection、Conversion circuit, etc。RLSeries static current relays for generators、Used as a starting element in overload and short circuit protection devices for transformers and power lines。The following Xiaobian will take you to take a look at the current relay schematic！

introduction：l、iVariable frequency capacity selection The capacity of the inverter should generally be selectedkVANumber as unit，However, the rated voltage of the AC motor is a fixed value，Accordingly, the voltage withstand value of the inverter switching element is determined，The working current of the switching element becomes the only parameter that affects the capacity of the inverter，In this way, the choice of the frequency converter capacity can be converted into the choice of its current。

introduction：Between prints，Sometimes molten consumables seep out from under the nozzle，It oozes out and is pulled by the nozzle to the next print，This results in what looks like a cobweb around the print，What we commonly call“wire-drawing”，This drawing is very difficult to remove。 backsetting：The reason for this phenomenon is that the rollback parameters of the slicing software are not set。Fortunately, this problem is easy to solve。Every slicing program has something called“backspace”Program of，Used to reduce the pressure of the nozzle，And prevent melted consumables from flowing out of the nozzle when the printer does not print。This program prevents more consumables from being pulled by the nozzle from the previous printing place to the next printing place。While printing continues，The printer pushes the consumables back into the nozzle。If the rollback setting is too high，You may clog the nozzle as you continue to print。So it may be necessary to do some experiments depending on the printer and consumables used。

introduction：Neumans cylinder production plant With the progress of The Times，The industrial sector is also becoming more developed。Neumans cylinder，It is a cylindrical metal part that guides the piston to move in a straight line。The working medium converts thermal energy into mechanical energy through expansion in the engine cylinders；The gas in the compressor cylinder is compressed by the piston and the pressure is increased。 Neumans cylinder manufacturers interpret the working principle： Determine the thrust and pull force on the piston rod according to the size of the force required for the work。Therefore, when selecting the cylinder, the output force of the cylinder should be slightly surplus。If the diameter is too small，underoutput，The cylinder is not working properly；But the bore is too large，Not only make the equipment cumbersome、High cost，At the same time, air consumption increases，Waste energy。In fixture design，Force-boosting mechanisms should be used as far as possible，To reduce the size of the cylinder。 Ameri
