Combined shaft seal for hydraulic fan of cooling tower

Abstract

The invention discloses a novel combined type spindle seal for a hydraulic power fan of a cooling tower. The novel combined type spindle seal for the hydraulic power fan of the cooling tower consists of a rubber type flat-plate seal and a fiber woven packing seal; the problem that a spindle seal of a hydraulic power fan leaks water can be effectively solved; and the purposes of self compensation, energy conservation and zero maintenance of the seal are achieved. According to the technical scheme, a spindle is provided with two seals which are the rubber type flat-plate seal and the fiber woven packing seal, and the two seals form the combined seal. The spindle seal mainly comprises fiber woven packing, a spring, a spindle jacket, a packing gland, a sealing seat, a rubber type flat-plate seal, a sealing pressure plate, a connecting piece and the like. The sealing seat is fastened to a top cover; the spindle jacket is hung on the spindle and is in contact with the fiber woven packing in the sealing seat so that water is sealed; and the rubber flat-plate seal is arranged on a lower flange of the spindle jacket and is tightly pressed through the sealing pressure plate. During working, the rubber flat-plate seal is in contact with the sealing seat due to inner water pressure, so that the water is sealed. The novel combined type spindle seal for the hydraulic power fan of the cooling tower is simple and novel in structure, convenient to mount and use, high in work efficiency and free of maintenance, and is energy-saving, environment-friendly and safe; running cost is saved; the novel combined type spindle seal is a great innovation for the field of spindle seals for the hydraulic power fan of the cooling tower; and the economy is high.

Description

technical field [0001] The invention relates to a combined main shaft seal, in particular to a combined main shaft seal for a hydraulic fan of a cooling tower. Background technique [0002] As a general circulating water cooling equipment, industrial circulating water cooling towers are widely used in many sectors of the national economy, such as electric power, petroleum, chemical industry, steel, textile and pharmaceuticals and other fields. By using the abundant hydraulic energy of the pipeline, the hydraulic fan is used to replace the motor, and the goal of energy saving and consumption reduction is promising. [0003] For a long time, as the core component of the hydraulic fan - the main shaft seal, its working efficiency is low, and the water leakage is serious during operation, which seriously threatens the normal operation of the bearing. On the one hand, a large amount of water leakage has caused an increase in the volume loss of the hydraulic fan, and water energy...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the problems of low working efficiency, serious running water leakage and poor reliability existing in the existing spindle sealing technology for hydraulic fans of cooling towers, and provide a combined spindle seal for hydraulic fans of cooling towers, which has high working efficiency , less water leakage, high reliability, and maintenance-free characteristics, and finally meet the requirements of high-efficiency, energy-saving, safe and stable operation of hydraulic fans
