My column-style steamengine

A special section just for steam engines and boilers, as without these you may as well fit a sail.

Re: My column-style steamengine - the Valves

Post by dampfspieler » Sun Oct 27, 2019 8:54 am

Hello,

for the feedwaterpump were made two "mushroom"-valves. At speed higher than 600 rpm the ballvalves destroy the ball seats in the pump body - experience from the operation of my steam lorry MARTIN. The valves are "pressed" with very light springs to its seats so they work ut to 1.500 rpm - experience from MARTIN.

The valve chest is placed at the upper end of pump chamber to allow the air to leave the system.

The valves in the condensate pump are rubber plate types (NBR). They are small enaugh and noisy in service.

Dietrich,

Good job on the check valves, I like the disc type check valves also. Ball checks are not as reliable.
