Summary of 100 technical questions and answers about pumps (Part I)
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 -
How to clean a liquid ring vacuum pump? You can’t go wrong with these 11 steps!
After working for a long time on a Liquid ring vacuum pump, there will be some dirt on the outside or inside of the pump. In this case, we have to clean it. External cleaning is relatively easy, but internal cleaning of the pump is difficult. The inside of the pump is usually caused by underworki...Read more -
Pumps commonly used in ultra-high vacuum systems
I. Mechanical pumps The main function of the mechanical pump is to provide the necessary pre-stage vacuum for the start-up of the turbomolecular pump. Commonly used mechanical pumps include mainly vortex dry pumps, diaphragm pumps and oil sealed mechanical pumps. Diaphragm pumps have low pumping ...Read more -
