All relevant units: According to the requirements of the "Evaluation Measures for Technological Small and Medium sized Enterprises" (Guoke Fazheng [2017] No. 115) and the "Guidelines for the Evaluation Service of Technological Small and Medium sized Enterprises" (Guoke Huozi [2022] No. 67), the eighth batch of 4005 planned technology-based small and medium-sized enterprises in our province in 2022 has been publicly announced on the "National Information Service Platform for Technological Small and Medium sized Enterprises" for 10 working days, The list of 3990 technology-based small and medium-sized enterprises in the eighth batch of 2022 will be announced through public announcement.

Mechanism and Principle of Ceramic Plunger Pump A. The ceramic plunger pump is composed of ceramic metering components (including ceramic plunger pump sleeve, plunger, slot valve metering rod), stainless steel inlet and outlet nozzles, and connecting components. B. The working principle of zirconia ceramic plunger pump 1. The downward linear activity of the ceramic column breeds negative pressure and sucks in liquid; 2. The upward linear activity of ceramic columns breeds positive pressure and squeezes out liquids. Good performance of ceramic plunger pumps 1. Extremely inert metal oxides, resistant to acid and alkali corrosion, high temperature resistance, and compliance with repeated disinfection and sterilization under high temperature conditions; 2. Ultra high material hardness: wear resistance, long service life (5-8 times that of chrome plated steel pumps), and minimal particle release. 3. The crystal layout exhibits zero porosity and dense material quality: the product appearance is extremely smooth, with minimal friction and minimal drug residue; 4. Minimal thermal expansion: The plunger gap is smaller, allowing for continuous operation without liquid, higher filling accuracy, and online washing and sterilization.

Corrosion resistant magnetic pump is a special type of magnetic pump mainly used for transporting liquids with corrosive media. Compared with ordinary magnetic pumps, corrosion-resistant magnetic pumps have higher corrosion resistance and wear resistance, and can operate stably in harsh working environments. Corrosion resistant magnetic pumps are usually made of special materials, such as polypropylene, fluoroplastics, ceramics, stainless steel, etc. These materials have good corrosion resistance and wear resistance. At the same time, the sealing structure of the corrosion-resistant magnetic pump has also been specially designed to effectively prevent leakage and media leakage, ensuring work safety and environmental protection. Corrosion resistant magnetic pumps are suitable for industries such as chemical, petroleum, pharmaceutical, electroplating, and power. They are mainly used to transport liquids with strong corrosive media such as acid, alkali, hydrochloric acid, sulfuric acid, hydrofluoric acid, sodium hydroxide, and organic solvents. Due to its high safety, stability, and reliability, it is widely used in the transportation of corrosive liquids in industrial production.
