The technical problems to be solved are: compact and reasonable structure, accurate feeding, stable performance, no pulse in feeding process, long service life, safety and reliability, easy installation and maintenance of microporous plate muffler. It is planned to recruit 3 senior mechanical design engineers, 2 Mechatronics engineers, 1 process design engineer and 2 mechanical design and automation engineers who are familiar with thermal power generation system. Main technical indicators: feeding speed range: 0-20r / s, feeding accuracy ± 0.05t/h, feeding power: 3-4kw, feeding power: 3-4kw, manufacturing muffler, feeding pipe diameter: dg150. The proposed projects are mainly the power of forklift - fuel cell and some related technologies supporting 1-5-ton forklift trucks, and it also needs talents related to fuel cells. Only when the project to be introduced reaches the practical level can industrialization be realized, and all performances can reach or exceed.
