What to do if the power outage prevents the single-acting slide valve from closing?
Everything said upstairs is absolutely correct; hurry up and use the manual mode, stop posting here. By the time the post is received, it will be too late.
1. On-site hydraulic valve shutdown. 2. Switch from hydraulic to manual mode, and use a manual valve to close it.
I don’t understand. Manual operation takes time; before starting to turn it, how should I control the pressure difference between the two devices? How can I ensure that there is a sufficient amount of fluid in the startup riser?
It should be the motor’s power loss-induced self-locking; if automatic protection is activated, that mode is better than self-locking, so there should be no impact. If it is a adjustment, go to the site promptly and make the changes manually using the control device; or if the motor loses power and locks up due to voltage fluctuations, starting the pump at the site will unlock it.
