Vacuum pump in vacuum perfusion process of practical application
There are many applications that use products to improve the environment. Ventilation is a necessary function in many environmental applications. For example, our vacuum pumps (vane vacuum pumps, screw vacuum pumps, roots vacuum pumps, oil-free vane vacuum pumps, oil-free piston vacuum pumps) and vacuum systems can be used for the following processes: compressed gas, material collection and ventilation. The application of imported vacuum pump in environmental protection industry includes biogas production, biogas transformation, biogas compression, vacuum perfusion and wastewater purification. This paper mainly introduces the practical application of the imported vacuum pump in the vacuum perfusion process.
One step in the vacuum infusion process is to vacuum. Material laid, clamping the pipe into the resin, began using import vacuum pumps, vacuum air to the system as far as possible, and check the air tightness, this step is critical, as there are funnelled, when resin imported air into the body into the system, the bubble will be funnelled to other local infiltration, even may the whole products scrapped.
Advantages of professional imported vacuum pump in vacuum perfusion process:
1. The glass fiber is impregnated with resin in a vacuum environment. Compared with the traditional manufacturing process, there are few bubbles in the product. With no excess resin left in the system, the glass fiber content is very high, up to 70% or even lower. The resulting product is lighter, stronger and very stable from batch to batch.
2, less resin loss: with vacuum process, the amount of resin can be accurate budget, for hand paste or spray process, because of the operator’s variability and difficult to control. The loss of resin can be minimized, and more importantly, the cost can be saved.
3. Uniform resin distribution: for a product, the pressure generated by vacuum in different parts is consistent, so the resin infiltration rate and content of glass fiber tend to be consistent. This is critical for parts that require a steady weight.
4, less volatile process: there is no brush or roller in the production process, will not cause the resin splashing or dripping phenomenon found, there will not be a lot of smell is now. Therefore, it can provide a clean, safe and friendly working environment and protect the physical and mental health of the operator.
5, the use of single-side mold: only one side of the mold can be used to get smooth and smooth products on both sides, can better control the thickness of the product, saving the mold manufacturing cost and time.
Common vacuum pumps include dry screw vacuum pump, water ring pump, reciprocating pump, slide valve pump, vane pump, roots pump and diffusion pump, etc. These pumps are essential in the application of vacuum process in various industries of China’s national economy. In recent years, with the rapid development of China’s economy, the downstream application industry related to vacuum pump has maintained a rapid growth momentum. At the same time, the vacuum pump industry in China has achieved a sustained, stable and rapid development under the joint pull of the continuous expansion of the application field of vacuum pump and other factors.
Vacuum pump in the practical application in the process of vacuum infusion is used to maintain the cooling water system starting, maintaining starting make water circulation pump and less power consumption to maintain water flow design, single-stage rotary vane vacuum pumps complete sets of equipment, usually with a starting valve, is the ideal choice for this type of application, because they can prevent the water quality within the piece of the suction pump.
