摘要： A technique facilitates well servicing operations by utilizing a hopper system to introduce a dry additive into a mixing tank. The hopper system comprises a feeder and a hopper that delivers the dry additive into the feeder. The feeder, in turn, enables introduction of the dry additive into the cement mixing tank in a controlled manner. When the hopper system is used on a transportable cementing unit, the hopper system may be mounted on a cement mixing tank and also may incorporate a hopper that is both expandable to accommodate a greater amount of dry additive and contractible to facilitate transport.

摘要： A system for dampening vibration in a pump includes a PTO-driven pump having a prime-mover side and a pump-side. The system includes a bulkhead interposed between the prime-mover side and the pump-side, the bulkhead having an opening therein. The system includes a vibration dampening plate having a thickness of at least 12 mm, where the vibration dampening plate is positioned between a bulkhead and a pump-side bearing flange or a prime-mover side bearing flange. The pump-side bearing flange or a prime-mover side bearing flange is coupled to the bulkhead at the opening therein. The system includes a bearing shaft extending through the opening in the bulkhead, the vibration dampening plate, the pump-side bearing flange, and the prime-mover side bearing flange.
