Herringbone gear pump
Thread Content
I have a few questions for everyone: 1. How can one determine the inlet and outlet of a herringbone gear pump from the gears? 2. What is the specific working principle of the safety valve at the upper end of the gear pump?
It’s best to upload a photo. Most safety valves are spring-based; once a certain pressure is set, they open when the pressure exceeds that level and then return to their original position.
The inlet and outlet of a gear pump are not determined by the gears; rather, they are determined by the rotation direction of the pump
Send the materials to the email. The gear pump has a simple structure; the herringbone teeth are formed by combining two gears together, with one tooth being left-handed and the other right-handed
Gear pumps belong to the category of positive displacement pumps, and safety valves are used to protect the pump from overpressure. If the outlet valve is not opened when starting the pump, the safety valve can then play a role in protecting it.
