Abstract
Official abstract text for this publication.
Closed circulation system for production of and continuously preparing a polymer solution, including a pneumatic stirrer inside and a charging hopper at a top of a drag-reducing polymer solution tank, a gas drainage pump, a submersible pump, and a compressed air pipe connected to a pneumatic diaphragm pump. A liquid inlet of the pneumatic diaphragm pump is connected to a liquid outlet of the drag-reducing polymer solution tank, and the gas drainage pump liquid discharge pipe and a liquid outlet pipe of the diaphragm pump leads to a circulation water pool; a liquid outlet of the submersible pump is connected to a liquid inlet of the drag-reducing polymer solution tank and a liquid inlet of the gas drainage pump respectively through a three way pipe. The pneumatic stirrer and pneumatic diaphragm pump operate at speeds, so the drag-reducing polymer solution is mixed uniformly and fed into the circulation water pool.
First claim
Opening claim text (preview).
What is claimed is: 1. A closed circulation system for improving an operating efficiency of a gas drainage pump, comprising a pneumatic diaphragm pump, a drag-reducing polymer solution tank, the gas drainage pump, a submersible pump, and a compressed air pipe, wherein a liquid inlet of the pneumatic diaphragm pump is connected to a liquid outlet of the drag-reducing polymer solution tank, and a liquid outlet pipe of the pneumatic diaphragm pump leads to a circulation water pool; a pneumatic stirrer is provided inside the drag-reducing polymer solution tank a charging hopper is provided at a top of the drag-reducing polymer solution tank; a liquid outlet of the submersible pump is connected to a liquid inlet of the drag-reducing polymer solution tank and a liquid inlet of the gas drainage pump respectively through a first three way pipe, and a liquid discharge pipe of the gas drainage pump is connected to the circulation water pool; and the compressed air pipe is connected to the pneumatic diaphragm pump and the pneumatic stirrer respectively through a second three way pipe. 2. The closed circulation system for improving the operating efficiency of the gas drainage pump according to claim 1 , wherein the liquid outlet of the drag-reducing polymer solution tank is provided with a steel wire mesh, and the steel wire mesh has a mesh count of 30 to 50.
