Problems solved by technology

The existing self-priming pump, its high cost
The self-priming ability is not strong, and the efficiency of water utilization is not high. Traditional water pumps have packing seals and mechanical seals, which will cause "running, popping, dripping, leaking" and other phenomena, and the service life will be reduced.
Cannot reach the goal of energy saving and emission reduction

Abstract

The invention provides a guide vane type dynamic-seal self-priming pump which is provided with a motor (1), a pump shaft (5) and a pump body (2). The motor (1) is arranged on the pump body (2), the left end of the pump body (2) is provided with a liquid inlet (3), and the right end of the pump body (2) is provided with a liquid outlet (4) connected with the liquid inlet (3). The pump shaft (5) is arranged on the perpendicular bisector of the pump body (2), an auxiliary impeller dynamic-seal structure is mounted on the pump body (2) and the pump shaft (5). A guide vane (6) is arranged at the position, close to the bottom end, of the pump shaft (5) and is fittingly connected with an impeller (7). By the fitting structure of the guide vane and the impeller, vapor and liquid separation is accelerated, cavitation performance and self-priming performance are improved, and hydraulic efficiency of the pump is improved simultaneously.

Description

Technical field: [0001] The invention relates to a self-priming pump, in particular to a guide vane type dynamic sealing self-priming pump. Background technique: [0002] With the progress of the times and the development of society, pumps are used more and more widely, especially in industries such as electric power, smelting, printing and dyeing, and environmental protection. The requirements for pumps are becoming more and more stringent, and their energy consumption is also increasing. The proportion of the national economy continues to increase, so it is imperative to improve the efficiency and sealing performance of the pump. The existing self-priming pump has high cost. The self-priming ability is not strong, and the efficiency of water utilization is not high. Traditional water pumps have packing seals and mechanical seals, which will cause "running, popping, dripping, and leaking" and other phenomena, and the service life will be reduced. The goal of energy saving...
