1、 Analysis on the causes of corrosion on the rotor surface of screw pump the feed medium of vacuum pump contains sulfur dioxide and water. Sulfur dioxide combines with water to form sulfurous acid. Sulfurous acid has corrosive effect on metal. In order to prevent corrosion of rotor and pump cavity, Teflon layer is coated on the surface of rotor and pump cavity. Corrosion of rotor and pump chamber indicates that the layer is damaged and sulfite has corroded to the pump chamber. 2、 Cause analysis of Teflon layer damage in rotor and pump chamber there may be three reasons for the damage of Teflon layer on the surface of rotor and pump chamber: first, solid particles enter the pump chamber and cause coating damage. Second, chemicals form colloid on the pump cavity and rotor 1、 Cause analysis of surface corrosion of screw pump rotor The feed medium of the vacuum pump contains sulfur dioxide and water. Sulfur dioxide combines with water to form sulfurous acid. Sulfurous acid has a corrosive effect on metals. In order to prevent corrosion of rotor and pump cavity, Teflon layer is coated on the surface of rotor and pump cavity. Corrosion of rotor and pump chamber indicates that the layer is damaged and sulfite has corroded to the pump chamber. 2、 Failure analysis of Teflon layer in rotor and pump chamber There may be three reasons for the surface layer damage of rotor and pump chamber: First, solid particles enter the pump cavity, which causes coating damage. Second, chemicals form colloid on the pump cavity and rotor, which carbonizes and hardens and destroys the coating of rotor and pump cavity. Third, other reasons. 1. Failure analysis of solid particles Check the pump inlet equipment and pipeline, and no free moving solid particles such as metal fragments and iron chips are found. 2. Analysis of colloidal carbon deposition failure Fig. 1 is a picture of the attachment on the inner wall of the pump inlet pipe. The substance is dark brown. After analysis, it contains iron, carbon and oxygen. It is a polymeric substance such as butadiene and sulfolane, which is bonded to the inner wall of the pipe. If the substance adheres to the pump cavity and rotor surface, it is easy to carbonize and harden, thus damaging the rotor surface layer. 3. Process factor analysis The gas phase outlet pressure of the vacuum pump is 80kPa (a), which is negative pressure, while the liquid phase outlet of the pump is normal pressure. Under normal circumstances, the liquid at the pump outlet cannot normally enter the underground liquid tank, resulting in backflow, resulting in the accumulation of liquid substances at the pump outlet. These liquid substances contain sulfurous acid, and the accumulation of sulfurous acid at the pump outlet forms impact corrosion to the vacuum pump, It should be said that the backflow of liquid at the pump outlet is the main reason for the corrosion of pump rotor and pump cavity.

It is used as a seal at removable and immovable joints or to fill small holes in vacuum systems. The joints do not need to be polished. Its hardness and viscosity are higher than vacuum sealing grease. Vacuum sealing wax can be divided into two types: 1. Vacuum sludge. It is a kind of plastic putty made by mechanically mixing refined petroleum grease with high viscosity and low vapor pressure and mountain surplus soil. The characteristics are: good plasticity and easy to form; At the same time, the plasticity changes little with temperature, has good adhesion to metal and glass, and is not easy to be monotonous when exposed to air. It is a black mud like homogeneous body, and the saturated vapor pressure is no more than 10-3. Toto. The application temperature range should not exceed 30 ℃ to avoid softening and deformation. It is used for temporary blocking of parts in the vacuum system that are slightly vibrated and often need to be disassembled, or suspicious air leakage areas found in the system. It is especially suitable for sealing glass pipes without grinding. But it can only be used in low vacuum parts. 2. Vacuum wax: it is made of petroleum residue oil with low vapor pressure and high asphalt content after proper treatment. The characteristics are: in addition to the low saturated vapor pressure and good adhesion to glass and metal, the shrinkage force is small, and the brittleness and non cracking will not change when the temperature changes greatly. It is used for permanent sealing at the grinding joint of metal pipeline in vacuum system and blocking sand holes or loopholes on glass instruments. Its saturated vapor pressure (at 20 ℃) is generally lower than 10-6 Torr, which can be used in high vacuum part. stay Try to make it condense or soften when using, but the temperature should not be too high. It must not be directly baked and heated with open fire. The heating temperature is below 100 ℃. There are 20 #, 50 #, 80 #, and the viscosity of 80 # is the largest.

Intelligence is to control the whole process of water ring vacuum unit with one key through the intelligent control of switch cabinet. Intelligence is also automation. How does the intelligent water ring vacuum unit work? The user must provide all kinds of requirements (pumping volume, working vacuum), working environment (weather data of the day, operating environment), the nature of the gas (what kind of gas, what kind of liquid, whether there is dust, whether there is corrosion, etc.) Vacuum pump factory Co., Ltd. will design, produce and form a comprehensive intelligent water ring vacuum unit according to the information provided by you, so as to ensure safe and smooth production How to improve the quality of your equipment? Every real entrepreneur hopes that his products will be appreciated by customers, and at the same time, there will be certain profits. In the process of product positioning and actual production, there will be a phenomenon of high opening and low operating In the mechanical equipment production industry, it often happens that our products are well done, but when we go to customers, there are many more problems, and at last, it makes a lot of trouble. The main reason is: in the selection of existing products, there is a big deviation. In order to reduce the cost, we only want low price, rather than sincere cooperation and win-win creation This is the fact that a good horse matches a good saddle (1) dental clinic equipment, medical microwave equipment, used to use oil vacuum pump or dry vacuum pump, because of its use conditions, it is difficult to bear the work of the above two kinds of pumps, vacuum pump factory Co., Ltd. developed water ring vacuum pump, specially designed and manufactured for medical equipment (2) generally, plastic machinery is not officially started up until more than ten days or more than a month after leaving the factory. Generally, the water ring vacuum pump is easy to rust and get stuck. At the same time, because the general water ring vacuum pump is dry before leaving the factory, if it is not started carefully, it is easy to cause the mechanical seal damage and make the pump unable to work, A series of special treatments were carried out to ensure 100% normal operation.
