Automotive sensors are now widely used。It is the input device for the car computer system,It can convert the information of various working conditions in the operation of automobiles into telecommunications numbers and lose it to the computer,So that the engine is in better working condition。There are a lot of sensors in cars,Determine the fault of the sensor,The sensor itself should not be considered alone,Instead, consider the entire circuit that failed。therefore,When looking for a fault,Besides checking the sensors,Also check the harness、Connectors and related circuits between sensors and electronic control units。Lets take a look at the main sensors in the car。
Operating instructions and Settings of pressure switches
The speed change of the motor adopts the connection mode of the winding,That is to say, by changing the number of magnetic poles of the rotating magnetic field of the motor to change its speed。
The four-frequency ASIC of displacement sensor has the function of phase discrimination and four-frequency subdivision at the same time,Two orthogonal square waves can be quadrupled to produce a double addition、Decrement signal,Double clock reversible counter can be sent to add、Decrement count,A microcomputer can also be sent directly(Including microcontroller)Perform data processing。
Solid-state relay wiring Solid-state relays are made of microelectronic circuits,Discrete electronic device,A contactless switch composed of power electronic power devices,Achieves direct drive high current load。The following Xiaobian take you to see how the solid-state relay wiring。
Performance introduction: 1.Fast speed Easy to install: The action speed is faster than the hydraulic transmission,And more stable than pneumatic transmission;If the formal booster cylinderDress backwards,The hydraulic oil will not be able to smoothly enter the oil chamber,The installation mode is formal installation or horizontal installation。 2.Easy to use Easy to maintain: Cylinder body installation is simple,Easy output adjustment,Easy to use and maintain;Because of simple structure,Therefore, the maintenance is easier than the oil pressure system; 3. Mold free: Compared with ordinary cylinder and hydraulic station,Theyre smaller than they are50%above;To meet the needs of the process,The impact pressure and working stroke can be stepless adjustable within the specified range; 4.Less trouble Low energy consumption: No oil pressure system temperature rise trouble;Continuous pressure or stop action,It doesnt have to be like a pure hydraulic system,The motor needs to run continuously,So it can save ene
Straight line moduleThere are several ways to call it that,Linear module、Cartesian robot、Straight slide table, etc,It is followed by linear guide、Linear motion module、Automatic upgrade unit of ball screw linear drive mechanism。The linear load can be realized through the combination of individual units、Curved motion,Automation is more flexible with light loads、More accurate positioning。 The linear module was first developed and used in Germany,The market is positioned in photovoltaic equipment,Loading and unloading manipulator、Cutting equipment、Gluing equipment、Patch equipment, etc,This kind of manipulator can bring convenience to the equipment in this industry:The unit moves fast、High repeated positioning accuracy、Light body weight、Occupies small device space、Long life。The range of applications of linear modules is expanding all the time,Run around the world。They run faster in my country,In recent years,The development of linear modules is even faster,Especially in Shenzhen,Do a lot,And the quality is go
Use of thrust ball bearings:Only suitable for bearing one axial load、On a machine with a lower speed,Only suitable for bearing one axial load、On a machine with a lower speed,For example, crane hooks、Instant water pump、Immediate centrifuge、jack、Like a crane hook、Instant water pump、Immediate centrifuge、jack、Low speed reducer, etc。Shaft ring of bearing、The seat ring is separated from the rolling element,Speed reducer, etc。Shaft ring of bearing、The seat ring is separated from the rolling element,Can be installed and disassembled separately。
Bearing clearance generally refers to the radial clearance of the bearing。The radial clearance of deep groove ball bearings can be calculated by the following formula。
