vacuum pressure impregnating equipment the use notes
The following seven points should be paid attention to when using vacuum pressure impregnating equipment
1. Before operation, check whether the motor running direction is correct to prevent the oil from injecting into the paint dipping cylinder;
2. Machines with separate active and manual buttons shall not be opened together to prevent damage to electrical components and violation of process operation;
3. Check the vacuum pump oil level should reach the standard scale;
4. The pressure oil in front of vacuum cylinder should reach 2 / 3 of the total volume;
5. Check whether there is air leakage or blockage in the pipe of vacuum machine;
6. If the cylinder seal ring is damaged, it can not rise and fall smoothly and needs to be replaced;
7. If the sealing of the window and the box of the dipping machine is good, it should be more sealed if it is not outstanding. If the sealing ring is not accurate to the vacuum, it should be replaced and the sealing should be strengthened with sealant. Every transmission part should be filled with oil once or twice a week.
Methods for improving reliability and maintainability of vacuum impregnating equipment
Considering the beauty of all the equipment, most of the system pipelines need to be set under the channel. When the channel cover plate is opened for maintenance, the components selected under the cover plate are required to be reliable and easy to maintain.
一、 Delivery back paint system, pressure system and other executive components. At present, automatic actuator can be roughly divided into three categories: electric, hydraulic and pneumatic. Electric spark may occur in electric components of paint dipping equipment, so it should be used less. The hydraulic components are accurate and reliable. However, the hydraulic components will inevitably leak less, which will affect the beauty of the equipment, while the pneumatic components will not spark, and even if there is a small amount of gas leakage, it is also attributed to no pollution gas, which just has the advantages that both do not have. Therefore, the actuator of this equipment adopts pneumatic components.
二、 A magnetic filter is added in the paint return pipeline
The foreign matters brought into the paint by electrical equipment in the process of vacuum pressure impregnation can be roughly divided into two categories
1. As for a small amount of oil, due to the self solubility of insulating paint, a small amount of oil will not have a great impact on the effect of impregnation in the process of transferring back paint;
2. If the iron filings are not removed effectively, it will not only affect the quality of the dip paint, but also block the short circuit and damage the sealing performance of the valve.
