What are the causes of wave soldering nozzle leakage?

Answer:

If the sprinkler after finishing his work, not timely back thimble reset, there will be a water column as the outflow flux. If it's near the warm-up, there's a security risk. The reason is: inside the nozzle, the rubber ring at the base of the thimble is relatively big with friction, leading to the slow return of the thimble under the action of the spring! Just put butter on the rubber ring at the thimble site.
Soldering nozzle leakage is the main problem of the sealing, the nozzle needle valve is opened and closed, the main spring may not return, can check whether there are elastic spring, and the sealing ring of the needle body may be worn, the nozzle is a certain life, suggestions can purchase spare parts, this can be a good solution the problem!
In fact, there are no more than two reasons: the screw is loose; the air valve is leaking and the flux is flowing out.
