First of all, we should have a more comprehensive understanding of all aspects of the tested object. It mainly includes: the properties of the tested object, whether it is condensable gas or non condensable gas, whether it is single or mixed, inert gas or active gas or corrosive gas; Whether the air flow state is steady or instantaneous, whether it is uniform or non-uniform; Whether the temperature is isothermal or non isothermal, high temperature or low temperature; Whether there are special conditions such as magnetic field, electric field, vibration, impact, acceleration, charged particles, radiation, etc. Secondly, according to the situation of the tested object and the research purpose, correctly select the vacuum gauge, and need to understand the principle, range and limitations of the selected vacuum gauge, so as to use the vacuum gauge correctly. Third, we should understand the interaction between the vacuum gauge and the measured object. The principles of various vacuum gauges are different, and its introduction may cause changes in some states of the measured object; At the same time, the gas in the measured object may also affect the vacuum gauge, change its performance and interfere with its work. Moreover, when introducing the technical characteristics of vacuum measurement, fozhen has mentioned that the measurement accuracy of vacuum measurement is not high due to many influencing factors and difficult to control. Therefore, in order to carry out ideal vacuum measurement, we must fully understand the above-mentioned problems, so as not to cause greater errors or errors. dry screw vacuum pump in EVA production process

When purchasing products, we should understand the quality of products, as well as the service and after-sales of brand manufacturers. Only in this way can we obtain more cost-effective services and products. Dry vacuum pump is a very common industrial equipment in the market, and it is widely used. So, how should dry vacuum pump manufacturers choose? What details should we pay attention to? Friends who want to know, let's have a look. 1、 Inspect the service system of the manufacturer The manufacturer of each product is different in terms of service system. We should choose the manufacturer of dry vacuum pump, and we must choose the manufacturer with perfect service system and after-sales service. The reason for this choice is that manufacturers with after-sales service can provide high-quality products and services to protect the legitimate interests of businesses. 2、 Price of consulting products When producing dry vacuum pumps, different manufacturers will choose different materials and use different technologies. Therefore, the production cost and price of products are different. When purchasing dry vacuum pump equipment, we should understand the price of the product and consult the function, service life and other aspects of the product. In this way, the product can be correctly evaluated. 3、 Understand the contents of the contract Before signing the commodity contract with the dry vacuum pump manufacturer, we should confirm the contents of the contract. For example, product specification, model, quality, etc. At the same time, we should also understand the production period of products and relevant technical standards. In this way, we can get more professional services. When selecting specific manufacturers, we should combine the above information. Regular and reliable dry vacuum pump manufacturers can ensure product quality and provide customers with high-quality after-sales service.
