high Vacuum Trimming Valves
FAQ
Product Introduction: This series of valves are manually driven precision control valves. They are reasonable in structure design, beautiful in appearance, high precision, small size, practical and reliable, and have good sealing performa...
The quality of vacuum pump oil depends on the viscosity and vacuum degree, and the vacuum degree depends on the value at different temperatures. The higher the temperature is, the more stable the vacuum degree is.Let’s learn more about the following:
I.Recommended oil viscosity range of v...
Recently, a user asked: why should magnetic inspection be done for vacuum pump during air transportation?I will tell you about the magnetic inspection in this issue
1. What is magnetic inspection?
Magnetic inspection, referred to as magnetic inspection for short, is mainly used to measure the str...

This series of Roots-type vacuum pumps cannot be used alone. It needs to be used in series with the pre-stage vacuum pump to increase the pumping rate of the pre-stage vacuum pump when the pressure is lower than 1.3×103~1.3×10-1 Pa. The structure is composed of two 8-sha...
1. Flange connection
This is the most commonly used form of connection in valves. According to the shape of the joint surface, it can be divided into the following categories:
● Smooth type: it is used for the valve with low pressure and convenient to process.
● Concave convex type: the working p...
