Intelligent integrated switch-type electric actuator comes with a control box, the so-called mechatronics. With liquid crystal display, can feedback 4 ~ 20mA standard signal, you can determine the valve's full open, fully closed, and the uncertain middle position, that is, switch control. Widely used in metallurgy, petroleum, chemical, water treatment and sewage treatment industries, applicable to butterfly valves, ball valves, plug valves, etc., as 90-degree rotary valves and similar equipment.
The intelligent integrated switch-type electric actuator is mounted on a reversible plate to adjust the torque control mechanism, stroke control mechanism, and opening degree indication mechanism. Intelligent integrated switch electric actuator button box has three buttons, the middle of the field and remote conversion button, the left side of the scene to close the valve button, the right is the scene to open the valve button, cover the button box for the remote control, remote DC 24V switch Contact control, open button box for on-site operation.
Installation of intelligent integrated switch-type electric actuators:
1. The bolts connecting the intelligent integrated switch electric actuator and the valve shall not be lower than 8.8.
2. When it needs to be disassembled, the manual handwheel should be rotated several times first, with the valve slightly open.
3. When the valve is not used frequently, it should be regularly checked and maintained and operated. The running time should not exceed 10 minutes.
4. When the intelligent integrated switch electric actuator is installed, the space required by the maintenance inspector to disassemble the components is ensured.
5. The intelligent integrated switch-type electric actuator device is a short-time working system, and the continuous working time shall not exceed the time specified on the nameplate.
6. When installing, disassembling and debugging, do not damage the sealing surface, seals and the explosion-proof surface of the explosion-proof electrical equipment. Apply anti-rust oil on the flameproof surface. The electrical cover should be tightly fastened to prevent rain or moisture. enter.
7. The installation form of the intelligent integrated switch-type electric actuator device has no principle requirements, but the motor is in the horizontal state, and the electric box cover is in the horizontal or vertical upward state as the recommended installation form, which is conducive to debugging, lubrication, maintenance and manual operation.
Curing Agent
Curing agents, also known as hardeners, are essential components of many polymer systems, including Epoxy Resins. Curing agents react with the epoxy resin to form a three-dimensional crosslinked network, resulting in a cured polymer with improved mechanical properties, chemical resistance, and thermal stability.
There are several types of curing agents, each with its own unique properties and applications. The most common type is amine-based curing agents, which react with the epoxy functional group to form a secondary amine and an alcohol. This reaction is exothermic and can be accelerated by heat, making it ideal for high-temperature applications.
Another type of curing agent is anhydride-based, which react with the epoxy group to form a cyclic acid anhydride and a hydroxyl group. These curing agents are typically used in applications where water resistance is critical, such as marine coatings and adhesives.
Other types of curing agents include phenolic, acid, and catalytic curing agents. Phenolic curing agents are used in high-temperature applications, while acid curing agents are used in low-temperature applications. Catalytic curing agents are used to accelerate the curing process and are typically used in combination with other curing agents.
The choice of curing agent depends on the specific application requirements, such as cure time, cure temperature, and final properties of the cured polymer. It is important to choose the correct curing agent to ensure that the final product meets the desired specifications.
In summary, curing agents are essential components of many polymer systems, including epoxy resins, and play a critical role in improving the mechanical, chemical, and thermal properties of the cured polymer. The choice of curing agent depends on the specific application requirements and must be carefully considered to ensure the final product meets the desired specifications.
