Application of vacuum system in oil deacidification processing
The following focuses on the application of vacuum system in oil deacidification processing, for your reference. Unrefined crude oils contain some amount of free fatty acids, and the process of removing free fatty acids from oils is called deacidification. The methods of deacidification include alkali refining, distillation, solvent extraction and esterification. Among them, the most widely used are alkali refining and distillation. Distillation deacidification method is also known as physical refining method, that is, the free fatty acid in crude oil is not neutralized by alkalis, but a refining method for deacidification by vacuum steam distillation. The distillation deacidification method usually uses a steam jet vacuum pump to achieve vacuum. This method needs to consume a lot of water vapor, so the water consumption is high, and a large amount of waste condensate will be formed, resulting in a slippery production site and a hot and humid working environment. Potential Security risks.
Application of Rotary Vane Vacuum Pump in Paper Industry
The paper industry is one of the basic industries in my country. The number of domestic pulp and paper enterprises is large and widely distributed. The transmission system of the old paper machine mostly uses a DC motor to drive each transmission roller shaft, which can achieve stepless speed regulation, but due to carbon The presence of brushes makes maintenance rather cumbersome. At present, vacuum pumps on the market are widely used in metallurgy, chemical industry, food, electronic coating and other industries. However, for paper-making vacuum pumps, due to the large vibration caused by the work of the vacuum pump during use, the quality of the working environment is affected; and During installation, it is unfavorable for installation, causing inconvenience in operation and reducing installation efficiency. Therefore, in view of the above problems, a special vacuum pump for papermaking is proposed. The rotary vane vacuum pump has the advantages of fast pumping speed, small volume, light weight, low noise, convenient maintenance, and high vacuum degree, which meets the requirements of vacuum pumps for papermaking.
Rotary vane vacuum pump maintenance skills
In actual operation, we will find that there are many types of common faults in rotary vane vacuum pumps, which can be divided into operation faults and performance faults. The maintenance technique of rotary vane vacuum pump is actually that once the vacuum pump fails, we need to analyze the cause of the failure, and then carry out appropriate vacuum pump maintenance according to the problem and reason. This is very critical and needs to be paid attention to by everyone. If you use the maintenance method corresponding to the cause of the failure to maintain the failure caused by this reason, it may cause secondary damage to the vacuum pump. Next, the editor will explain the operation and maintenance of the lower rotary vane vacuum pump, as well as the maintenance methods of common faults.
