The temperature prevents corrosion of the friction surface and transmits power through the lubricant, and acts as a seal and damping. Therefore, correct, reasonable and timely lubrication of equipment, the normal operation and maintenance of pharmaceutical equipment, so that it can be in a good state of technology, give full play to the use of pharmaceutical equipment, improve the quality of medicines, and ensure the smooth progress of pharmaceutical production, All have important meanings.
2, lubricant types and performance indicators
Due to the special nature of pharmaceutical production, pharmaceutical equipment needs to have good lubrication in order to maintain its operating state, and to ensure the production quality to prevent secondary pollution that may occur in equipment, and to avoid all factors that may pose a threat to drug safety. Therefore, GMP will clearly The structure, performance, parameters, etc. of the pharmaceutical equipment and the related substances such as lubricants used as the source of pollution are listed as the focus of control and performance verification of the equipment in use. Therefore, mastering the basic knowledge of lubricants is the key to the correct choice of lubricants to ensure good lubrication and quality of the equipment.
2.1 Types of lubricants
2.1.1 Liquid lubricant
Liquid lubricants mainly include mineral oil, animal and vegetable oils, synthetic oils and water. These lubricants can form an oil film between the friction pairs to completely separate the surfaces of the two friction surfaces, presenting the friction of liquid molecules between the laminar flows in the oil film, which has reached lubrication. the goal of.
2.1.2 Semi-solid lubricant
Semi-solid lubricants mainly include animal fat, mineral grease, synthetic fat, etc. These lubricants can form a semi-solid adsorption film between the friction pairs for lubrication purposes.
