Nitrogen solenoid valve Solenoid valves are industrial equipment controlled by electromagnetism,It is a basic element of automation used to control fluids,actuator,Not limited to hydraulics、pneumatic。Nitrogen solenoid valves are generally explosion-proof solenoid valves,If its pure nitrogen,The two solenoid valves are the same。But if nitrogen is mixed with other gases,Therefore, it is better to use explosion-proof solenoid valves if nitrogen is used。I believe that some people do not know the installation steps of safety valves,The following Feng Ye Xiaobian will take you to understand what matters to pay attention to the installation of nitrogen solenoid valves。
SMCAir cylinder SMCCylinder A cylinder-shaped metal part in which the piston is guided by straight reciprocating motion。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。Reciprocating linear movement of the cylinder can be divided into a single acting cylinder、Double acting cylinder、Diaphragm cylinder and impact cylinder4Kind of。The following Feng Ye Xiaobian will take you to understandSMCWorking principle of the cylinder。

Double row deep groove ball bearingsThe design is basically the same as that of single row deep groove ball bearings。The raceway with the shaft shape of the deep groove ball and the excellent fit between the raceway and the steel ball。Double row deep groove ball bearings bear radial loads in addition,It can also withstand axial loads acting in both directions。 Standard double row deep groove ball bearings are4200A、4300Atype。AThere is no ball filling gap。Two reinforced nylon cages are inserted from each side of the bearing。Double row deep groove ball bearings in addition to having higher than single row deep groove ball bearings1.62Times the radial load capacity outside,It can also withstand axial loads。 Double row deep groove ball bearing features: Double row deep groove ball bearings are suitable for applications in a bearing configuration where the load capacity of a single row deep groove ball bearing is insufficient。For double row deep groove ball bearings with the same outer diameter and inner d
Seamless conveyor beltAlso known as jointless adhesive tape,English nameseamless fusing machine belt,High strength glass fiber yarn and Kevlar(Aramid fiber)The cylindrical fabric is woven by circular weaving equipment,Teflon resin is coated with unique technology(PTFE)made-up。Therefore, seamless conveyor belts are several times more expensive than ordinary conveyor belts with joints。 The characteristics of seamless conveyor belt: 1、Because the seamless conveyor belt is coated with Teflon,So it has extremely high temperature resistance,anti-tack; 2、Compared with a jointed adhesive tape,It overcomes the phenomenon that the conveyor belt interface is easily broken in the past; 3、The seamless belt overcomes the poor shape stability caused by the unequal girth of the joint、Deviation and other phenomena; 4、Smooth and fine surface,It is better to process ultra-thin adhesive lining、Better resistance to bending fatigue,durable; 5、The seamless conveyor belt has a longer operating life than any Teflon conveyor belt con
Working principle of current relay Current relay is a common component in power system relay protection。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。Believe that more people prefer to see pictures than words,The following Feng Ye Xiaobian will take you to understand the working principle diagram of the current relay。
