The pump head of the low-temperature reciprocating liquid pump is stuck.

The drive belt was broken twice within a month due to the pump head getting stuck. What causes the pump head to get stuck during operation? ? The method used by a blacksmith is to pour water on the pump head for a while, then move the hub of the pump back and forth so that the piston can move forward and backward, after which the belt is reinstalled and the pump can be used again. I want to ask what caused this jamming; it needs to be completely resolved
Just dismantle it; it’s very simple. Just dry it out and clean it. It’s not a difficult task; it can be done without any special fitting skills.
Why does this happen? The other one has been running without any problems; what could be causing the inside to not dry out?
Rinse the pump head with water for a while and move it back and forth; that should fix it. I want to know what causes this jamming. The other one has been running for a long time without this issue.
Then it could be considered thawed. Since this is a cryopump, is there a medium that undergoes a low-temperature phase transition? But it’s not scientific either for the backup machine to work normally. The best approach is to carry out repairs as soon as a problem arises next time, to find out exactly where the issue lies
If it can be solved by watering, then either the growing medium has hardened and stuck, in which case hot water is needed, or the high temperature has caused expansion and resulting sticking, in which case cold water is required; it depends on which situation applies to you.
Liquid oxygen, around -180 degrees.
