Embodiment

[0019] Specifically, a connection method for the Johnson tube in the backwash filter includes the following steps in actual operation:

[0020] Step S1: The end face treatment of the connection of the Johnson tube is to process the end faces of both ends of the Johnson tube by means of line cutting. Compared with the method of grinding and flattening in the prior art, the technological process of wire cutting is simpler. When the end face is processed by wire cutting, not only can it be formed at one time, but also the gap between the two ends of the Johnson tube can be greatly reduced.

[0021] Wire cutting is a method in which an electric machine tool cuts metal by electrocorrosion with molybdenum wire. It is a unique special processing method in metal cutting equipment. Wire cutting can well meet the process of high-precision processing.

[0022] Step S2: The adjustment process of connecting the Johnson tube is carried out when the flatness of both ends of the Johnson tu...

Abstract

The invention discloses a connection method of a Johnson pipe for a reverse-washing filter. The connection method of the Johnson pipe for the reverse-washing filter comprises the steps of connection end face treatment of the Johnson pipe, adjusting treatment of the connected Johnson pipe, welding treatment of the Johnson pipe, and fastening treatment of the Johnson pipe. By means of the connectionmethod of the Johnson pipe for the reverse-washing filter, the problem that the two ends of the Johnson pipe are hard to seal due to the special structure of wire winding is successfully avoided, andthe sealing performance of the Johnson pipe is better. Moreover, an original complex machining process is simplified, the welding procedures are reduced, and the process is simple and stable. The process requirement of Johnson pipe connection can be met better.

Description

technical field [0001] The invention relates to the technical field of filter production, in particular to a connection method for Johnson tubes. Background technique [0002] Johnson tube can be widely used in oil, gas, water well sand control, chemical industry, environmental protection industry, Johnson tube is particularly prominent in the water treatment industry, Johnson tube is the most widely used in various water resources and collection resin filter screens A sort of. In the production process of the filter, if the connection of the Johnson tube is not well sealed, the production process of the filter will be affected, thereby affecting the production process of the filter element. The sealing effect of both ends of the Johnson tube directly determines the filtering effect of the filter cartridge, so the sealing of the Johnson tube is very important in the process of filter production. [0003] In the prior art, the Johnson tube is connected by grinding both ends...
