introduction:Four characteristics of electric pump: 1、Small weight,Easy to use,High working pressure。 2、Single stage pumping station:Simple structure,Can obtain greater work pressure。 3、Two-stage pumping station:Low pressure,high,Low pressure pumps supply oil simultaneously,Larger output flow can be obtained。High pressure hour,The low pressure pump automatically returns the oil without load through the relief valve。Reduce power consumption。

introduction:The highlight of the classifier compared with other components:The classifier relies on a gapless fit between the CAM and the needle roller(The gearing mode is similar to worm gear drive),A device for repeated transmission operations along a given CAM curve。cylinder(barrel)graduator:Platform type cylindrical divider for heavy load。The disk body of the divider is provided with a buffer device,The very large chain reduces the impact of rotational inertia when the index plate rotates,At the same time, the accuracy of the classifier is increased,Increased the service life of the index plate。

introduction:Raw material for cable tow chain,Because the outer sheath made of different improved materials has different functions,reactiveUVfunctional,Resistant to low temperature,There are oil resistant and cost optimized ones。But all of these outer jackets have one thing in common,It has high wear resistance,It doesnt stick to anything。Since the outer sheath of the cable tow chain must be highly flexible and also have a support function,So the one you should choose is high-pressure molding。

introduction:Due to the intermittent splitter mounting surface relative to the input、The vertical or parallel degree of the output shaft is high,The installation base of the equipment must ensure that the input of the splitter、Output shaft direction and input required by the device、Output direction coaxial。No eccentricity or deflection。In addition,Intermittent divider body mounting,The following points should also be noted。 1、The intermittent divider is a high-precision segmentation mechanism obtained by precise machining and correct assembly adjustment。User before use,You cant make adjustments、disassembly、assemble。 2、Verify that there is no damage to the mounting surface of the intermittent divider,If there is damage,It needs to be trimmed with a whetstone。

introduction:3DThe basic principles of printing towards3Dprint,The first thing to figure out:Its name is actually inaccurate。true,3DThe printing process is essentially2D(two-dimensional)print,Just need to2DPrint on top of it over and over again、Layer upon layer,Up to a piece3DFinal product forming。 usual,2D There are many ways to print,But all require the ink to be stuck to paper or card。Ink is a complex liquid,Per dye、Solvents and other substances。The ink remains wet when not in use,Once printed on paper by the printer,After contact with air,It takes on its color and dries immediately。The ink adds up little by little,Form letters on paper、Text and pictures,When it dries, it stays on the paper,And keep it permanently。

introduction:pnozSafety relay operation A safety relay is a combination of several relays and circuits,In order to complement each others abnormal defects,Complete function of relay with correct and low error operation,The lower the error and failure value,The higher the safety factor,Therefore, it is necessary to design a variety of safety relays to protect different grades of machinery,The main objective is to protect machine operators who are exposed to different levels of risk。

introduction:LCD switch power supply part withCRTThe basic principle of displays is similar。therefore,They also have many similarities in their overhaul。For this part of the circuit,The common failure phenomenon is to turn on the fuse tube、Power-on no output、There is an output but the voltage is high or low,Because we are familiar with this kind of failure,Therefore, the following brief introduction of this part of the circuit maintenance ideas。

introduction:The limit access switch has several conditions: first,Due to prolonged touch,There will be a deformation of the approach switch。Cause poor contact。 second,Because its mechanical,This results in mechanical jitter,For the rear control circuit,Need to add anti-vibration circuit。 third,The proximity switch frequency is not high,More per second20Time or so,In some cases where high speed limits are required,I wont be able to meet the needs。 For the above three disadvantages,The inductive proximity switch makes up for it。
