Embodiment Construction

[0025] The present invention is a circlip type filter screen of a main shaft sealing water filter which can be decomposed and cleaned and is easy to replace. The clamp sleeve of the clamp spring type filter screen of the present invention is made of stainless steel, and specifically includes: clamp sleeve 1, filter screen 2, Pressure ring 3 and circlip 4. The ferrule 1 and the filter screen 2 are connected by a circlip 4, and the filter screen 2 is also provided with a pressure ring 3 to fix the filter screen 2 in the ferrule 1. The specific structure is as follows Figure 1-Figure 3 as well as Figure 10-Figure 11 Shown.

[0026] The following is a detailed introduction to each component:

[0027] Filter 2: According to the required size, the whole stainless steel filter is crimped, and then the joint is welded and sealed to make the filter cylindrical. The opening of the filter is provided with an outer edge, such as Figure 4-Figure 5 Shown.

[0028] Pressure ring 3: According to...

Abstract

The invention belongs to the technical field of hydraulic machines, and particularly relates to a spindle seal water filter clamping spring type filtering net capable of being decomposed to be cleaned and easy to replace. The spindle seal water filter clamping spring type filtering net comprises a filtering net body and is specially formed by connecting a clamping sleeve with the filtering net body through a clamping spring piece, and a pressing ring is arranged on the filtering net body; due to the fact that a filtering net and joint decomposition structure is adopted, in the overhauling process, the filtering net body can be thoroughly cleaned; due to the fact that the fixed joint is made of a stainless steel material, the joint is not prone to being damaged, and the service life of the fixed joint is longer than that of a plastic joint; due to the fact that a clamping spring type structure is adopted, the requirement for the material and the shape of the filtering net body is not high, and material taking is wide; the manufacturing cost is low, imported elements can be replaced, the difficult purchasing problem is solved, the service life of the filtering net can be obviously prolonged, and the production cost is greatly reduced.

Description

Technical field [0001] The invention belongs to the technical field of hydraulic machinery, and in particular relates to a circlip type filter screen of a main shaft sealing water filter that can be decomposed and cleaned and is easy to replace. Background technique [0002] The main shaft seal is an important part of the hydraulic turbine system, which can prevent pressure water from penetrating into the guide bearing between the main shaft and the top cover. Generally, there are high requirements for the sealed water supply, and there should be no impurities in it, otherwise the impurities will accumulate in the sealed working cavity, causing the seal to not work properly, so the filter of the main shaft seal water filter plays a vital role The role of. The filter used in our factory at this stage is the original imported product of the water filter, and the filter is connected with the plastic fixed joint as a whole. This kind of product has the following disadvantages: [00...
