Chemical accessories are an important component of chemical industry production,widely used in various chemical equipment and machinery to ensure the smooth progress of chemical production.Chemical accessories manufacturers have a wide variety of types based on their different uses and functions,mainly including the following categories:
一、Mechanical parts
1.Bearing:supports the mechanical rotating body,reduces its friction coefficient during motion,and ensures its rotational accuracy.
2.Gear:It is an important transmission component in mechanical equipment that transmits power through interlocking.
3.Coupling:Connecting two shafts or shafts with rotating parts,rotating together without detachment or relative sliding during the transmission of motion and power,thereby ensuring transmission efficiency and accuracy.
4.Seals:Components that prevent fluid or solid particles from leaking between adjacent bonding surfaces and prevent external impurities such as dust and moisture from entering the interior of machinery and equipment.
二、Pipe fittings
1.Flange:used for connecting pipelines and equipment,connecting them as a whole through bolt connections,making it easy to disassemble and maintain.
2.Joint:Used to connect pipelines or pipelines with equipment.Depending on the connection method,it can be divided into threaded joints,welded joints,sleeve joints,etc.
3.Valves:Used to control the flow of media in pipelines,including globe valves,regulating valves,check valves,etc.
4.Pipeline bracket:used to support and fix pipelines,ensuring their stability and safety.
三、Instrument accessories
1.Sensor:used to detect various physical or chemical quantities in the chemical production process and convert them into measurable signals.
2.Transmitter:Convert the signal detected by the sensor into a standard signal(such as 4-20mA,0-10V,etc.)for remote transmission and display.
3.Executor:Automatically adjust the opening or speed of valves,pumps,and other equipment based on control signals,thereby achieving precise control over the chemical production process.
四、Security attachments
1.Safety valve:When the pressure inside the equipment or pipeline exceeds the set value,it automatically opens the discharge pressure to prevent damage to the equipment or pipeline due to overpressure.
2.Explosion proof film:used to prevent equipment or pipelines from exploding due to excessive internal pressure.
3.Emergency exhaust device:In emergency situations,quickly discharge the medium inside the equipment or pipeline to reduce pressure and prevent accidents.
In summary,there are numerous types of Chemical accessories,each of which plays an indispensable role.In chemical production,the correct selection and use of Chemical accessories are crucial for ensuring the stability and safety of the production process.
