How to choose a suitable vacuum pump main pump?
Sometimes, the demand for vacuum in enterprise production requires multiple vacuum pumps to be connected in series to form a vacuum unit to meet the requirements. In a stable and reliable vacuum system, the selection of the main pump is particularly crucial. The selectio...Read more -
What is the difference between a single stage rotary vane vacuum pump and a double stage rotary vane vacuum pump?
Rotary vane vacuum pump belongs to variable volume vacuum pump, which is a vacuum pump that is equipped with a biased rotor that rotates in the pump chamber, causing periodic changes in the volume of the pump chamber chamber separated by the rotary vane to achieve air ex...Read more -
How to choose the appropriate vacuum pump model?
In the process of communicating with customers about the selection of vacuum pumps in Super Q, we need to understand the level at which the working vacuum degree of the process needs to be maintained in vacuum applications. Finally, the ultimate vacuum degree performance of the selected vacuum pu...Read more -
What is the function of the gas ballast in an oil sealed vacuum pump?
Many people may see gas ballast in the instructions of some oil sealed vacuum pumps. For example, there may be two types of vacuum degree for rotary vane vacuum pumps: one is the value of gas ballast on, and the other is the value of gas ballast off. What is the role of the gas ballast in this? ...Read more -
Rotary vane vacuum pump oil spray, how to check and deal with?
Rotary vane vacuum pumps are used as oil sealed pumps most of the time. During the use, some oil and gas will be expelled together with the pumped gas, resulting in oil spray. Therefore, rotary vane vacuum pumps are usually equipped with oil and gas separation device at the outlet. How can users ...Read more -
What are the common technical terminology of vacuum pumps?
Technical terminology for vacuum pumps In addition to the main characteristics of the vacuum pump, ultimate pressure, flow rate and pumping rate, there are also some nomenclature terms to express the relevant performance and parameters of the pump. 1. Start-up pressure. The pressure at which the ...Read more -

1. What is a pump? A: A pump is a machine that converts the mechanical energy of the prime mover into energy for pumping liquids. 2. What is power? A: The amount of work done per unit of time is called power. 3. What is a effective power? In addition to the energy loss and consumption of the mach...Read more -
These three faults occur frequently in Roots pumps in vacuum process applications? Corrective measures for you!
Many vacuum process installations are equipped with a Roots pump on top of the pre-stage pump, both to increase the pumping speed and to improve the vacuum. However, the following problems are often encountered in the operation of Roots pumps. 1）Roots pump trips due to motor overload during star...Read more -
Common vacuum terms
This week, I have compiled a list of some common vacuum terms to facilitate a better understanding of vacuum technology. 1、 Vacuum degree The degree of thinness of the gas in a vacuum, usually expressed by “high vacuum” and “low vacuum”. High vacuum level means “goo...Read more -
Causes of High Temperature of Screw Vacuum Pump and Cooling Measures
1. The number of fan blades is small, and the air volume generated is small. 2. The fan speed is low, the wind pressure and air volume are small. 3. The motor has high power and high current, resulting in high temperature. 4. Dust and oil are attached to the motor,...Read more -
Molecular pump characteristics and common troubleshooting
The molecular pump is a vacuum pump that uses a high-speed rotor to transfer momentum to the gas molecules so that they gain directional velocity and are thus compressed, driven towards the exhaust port and then pumped away for the front stage. Features Name Features Oil lubricated mole...Read more -
Classification of vacuum pumps
The equipment that can expel gas from a closed container or keep the number of gas molecules in the container decreasing is usually called vacuum obtaining equipment or vacuum pump. According to the working principle of vacuum pumps, vacuum pumps can basically be divided into two types, namely ga...Read more
