What is the impact of an increased weight of the piston body in a vertical piston vacuum pump?
Thread Content
The oil-free vertical piston vacuum pump used in my home works with chloromethane gas, and its piston cylinder is made of cast aluminum in the original design. Due to the reaction between the medium and cast aluminum, there is a high risk of the formation of aluminum methylide; therefore, it is planned to replace the piston body with one made of 316L stainless steel. However, this will increase the weight by approximately 1.5 times. What impacts might such a replacement have on the operation of the vacuum pump?
Did you modify it on your own? Didn’t you consult the manufacturer? I personally think it will have an impact on the moving parts
The manufacturer advised against making any modifications, but it was still necessary to do so.
The motor power remains unchanged; the main issue is that an increase in weight leads to excessive inertial forces on the piston, which can cause vibration or damage to the unit. Therefore, I would like to know what are the effects of an increased piston weight?
