Structure and working principle
1. Structure: The ceramic filling metering pump is composed of ceramic metering parts (ceramic pump sleeve, rotary valve, metering rod), stainless steel inlet and outlet nozzles and connectors. 2. Working principle of ceramic filling metering pump:
(1) The rotary valve port is aligned with the liquid inlet, and the ceramic column moves downward in a straight line to generate negative pressure and suck liquid;
(2) The rotary valve port is aligned with the liquid outlet, and the ceramic column moves upward in a straight line to generate positive pressure and discharge the liquid.
Cleaning and Sterilization
1. Cleaning procedure:After cleaning with pure water, rinse with water for injection; long-term storage and initial use, need to remove the pyrogen, soak in 1~2% NaoH for 30 minutes, be careful not to use hot lye (the temperature should not be higher than 40°C), and the sealing ring should not be used Soak in lye for too long, otherwise the elasticity will deteriorate.2. Sterilization procedure:It can be sterilized by dry heat or high-pressure humid heat steam: but since the sealing ring can only withstand the temperature of 160°C, the sealing ring should be removed before dry heat to sterilize the sealing ring. High pressure moist heat steam. (It is recommended to use high-pressure moist heat steam for sterilization, the sterilization temperature is 121°C, the pressure is 0.1MPa, and the time is 30 minutes).3. Precautions for cleaning and sterilization:(1) Do not contact stainless steel with chlorine-containing chemical solutions to prevent corrosion of stainless steel parts. (2) Do not immerse the ceramic metering element in hot water above 40°C when cleaning. The ceramic plunger and ceramic sleeve should be cleaned separately. (3) When sterilizing, the rotary valve, ceramic sleeve and measuring rod should be placed in a special sterilization box, and the ceramic rod and ceramic sleeve should be hung vertically for moist heat sterilization to prevent deformation and bending due to heat; before installation and operation The temperature of each part naturally drops to room temperature. Before the temperature of the pump body drops to room temperature, damage to the components due to sudden cooling should be avoided. (4) Since the hardness of ceramics is greater than that of metals, the contact between ceramics and metals will make the surface of ceramics dirty. Use a small amount of concentrated sulfuric acid (hydrochloric acid) to clean; if there is yellow dirt on the pump body, soak it in 10% oxalic acid for 5-10 minutes, and then rinse it with water for injection. (5) Since the hardness of ceramics is greater than that of stainless steel, the contact between ceramics and stainless steel will cause the surface of ceramics to adhere to stainless steel and cannot be removed, which may cause poor operation or non-action of the filling pump. cause damage. It is recommended to use non-metallic materials as storage containers for cleaning and sterilization.
