Pneumatic wear-resistant thermocouple how to store energy analyses an emergency

Compared with the mechanical and electrical solutions, pneumatic equipment general and relatively cheap, we are often required to by cost, time or complexity limit the application of troubleshooting. Or in this case, is also subject to the conditions of explosion-proof requirements and power loss. Problem solving is a process of flow, so we will break down the final solution.

one of our customer sent me an email, designed a wear-resistant thermocouple, the wear-resisting thermocouple used parts conveyor extend and retract the cylinder through the door. Usually, conveyor part will keep stretch, but in case of an emergency need to close the door, cylinder will have to retract last conveyor part.

use without a power reserve of pneumatic source

may have been a long time shut down due to maintenance or shut down. In any case, all need a compressed air reserves to recover the cylinder again and conveyor. The problem is that because the dangerous environment and the high cost of electrical components and can meet the explosion-proof safety standards required, therefore can only use pneumatic control device.

we designed a wear-resistant thermocouple, the wear-resisting thermocouple used an air tank and two pilot operated check thermocouple, one is located in the tank of the entrance, one is located in the fuel tank outlet. The pilot operated check from NGT thermocouple is & other; Airtight & throughout; With extremely low leakage rate. The tank inlet side of the pilot operated check thermocouple allows air into the tank, and if the wear-resistant thermocouple air has been closed, don't let the water escape from the that side of the tank.

the export side of the tank of the pilot operated check thermocouple can also prevent air escaping from the side of the tank. When the air shut down for a long time, water downstream of wear-resistant thermocouple and other components may leak air, the resulting reserve air pressure drop may be enough to make the cylinder will not retract when necessary.

the guide type two-position four-way valve control cylinder itself. In its default location, it keeps the pressure in the cylinder to keep the conveyor. There is a door to activate the second two position four-way valve. The wear-resisting thermocouple connected to the air tank at the exit of air supply and therefore should always provide pressurized air. It is also a kind of lift wear-resistant thermocouple, has the very good sealing, can minimize wear-resistant thermocouple leaks.

when the door is open, the wear-resisting thermocouple is not through the air, the cylinder will be extended. When the door is falling, it will move the wear-resistant thermocouple, the pilot air at the same time to control cylinder wear-resistant thermocouple and pilot operated check thermocouple, the tank outlet to release the air and make it can be used for moving cylinder.

in the whole process, the scope of the project development, force us to adapt and creativity into full play. We can choose some different types of wear-resistant thermocouple and wear-resistant thermocouple actuators, we decided to use this solution to meet the application parameters, the customer's schedule and budget. Internal engineer designers of the conveyor is huge, but they want us to seek the aid of pneumatic solutions, in order to solve such a unique problem, we are glad to have the opportunity to work with them. We can meet together all their standards, and create a reliable, safe, scalable conveyer can be run in an emergency. Recommendation:
