4. User Intent Targeted FAQ Table
Customer Frequently Asked Question | Professional Field Engineer Answer |
Can GH3101 serial parts directly replace original 3NB-1600F mud pump factory parts? | All GH3101 coded parts adopt original OEM drawing size, full thread and mounting hole matching, no on-site modification needed for direct replacement. |
What is the difference between 5-1/2inch hardened liner and 6inch ZPEC liner? | 5-1/2inch FD45655 liner fits conventional low-weight mud; ZPEC 6inch liner with matched seal is designed for high-density weighted mud working conditions. |
Which consumable needs priority replacement for frequent stuffing box leakage? | Priority replace GH3101-04.05 seal gasket and worn stuffing box body, and apply 242 sealant on joint surfaces during installation. |
What pressure range does YK-150 pressure gauge adapt to on 3NB-1600F pump? | This explosion-proof gauge supports 0-40MPa full working pressure monitoring, calibrated specially for 3NB-1600F fluid end pipeline pressure test. |
How to reduce gear transmission offset failure on power end? | Use matched GH3101 adjusting gasket and locating ring(I) to adjust gear clearance, fasten main bolts with standard torque and install standard anti-loosening washers. |
