Problems solved by technology

In actual production, welding slag residues are likely to be produced in the way of bump welding, so that after the filter part is connected with the end cover, impurity particles are introduced into the cylinder and the compressor is blocked, which seriously damages the working performance of the compressor and causes the whole machine to have a large Potential quality hazards; in addition, bump welding damages the surface quality of the steel plate, and the surface of the solder joints is prone to blackening and rusting, which damages the firmness of the connection and reduces the service life of the gas-liquid separator
The welding method of furnace welding has high production cost and low efficiency, which cannot meet the economic needs of enterprise production and development

Embodiment 1

[0050] See figure 1 , figure 2 and image 3 ,in, figure 1 It is a structural schematic diagram of the end cap assembly described in the first embodiment; figure 2 for figure 1 Schematic diagram of the bottom-view structure of the end cap assembly shown; image 3 for figure 2 Cutaway view of end cap assembly shown.

[0051] Without loss of generality, as Figure 1 to Figure 3 As shown, the end cap assembly 1 in this embodiment includes an end cap body 11 and a filter component 12 , and the end cap body 11 and the filter component 12 are fixedly connected. Wherein, the filter component 12 has a filter screen 122 and a filter screen seat 121 fixedly matched with the filter screen 122; the end cover body 11 has a cover body 111 and a flange 112 provided with a locking portion 1121, and the locking portion 1121 is connected to the cover body A fixed section is formed between 111, so that the edge of the filter component 12 is fastened in the fixed section, and the weldin...

Embodiment 2

[0087] See Figure 21 and Figure 22 As shown, among them, Figure 21 It is a schematic structural diagram of the assembly equipment described in the second embodiment; Figure 22 for Figure 21 Schematic diagram of the structure of the positioning table defining the end cap assembly shown in . In order to clearly show the difference between this solution and the first embodiment, components and structures with the same function are marked with the same reference numerals.

[0088] In this embodiment, compared with the first embodiment, the main bodies of the two are exactly the same. The difference is that this solution takes a different approach to the design of the radial limiting section 31 of the positioning platform 3 . Specific as Figure 22 As shown, the radial size of the radial limiting section 31 is larger than the size of the positioning table 3 without the radial positioning section, so that the requirement for the axial dimension of the radial positioning se...

Abstract

The invention discloses an end cover assembly. The end cover assembly comprises an end cover body and a filtering part which are fixedly connected, wherein the filtering part is provided with a filter screen base and a filter screen, the end cover body is provided with a cover body and a turnup edge which is provided with a locking part for fixing the filtering part, the locking part and the cover body form a fixing interval for clamping and fixing the filtering part, and the locking part is a protrusion or an annular protruding edge which is sunken from the peripheral face of the turnup edge to the interior of the end cover body. Due to the improvement of the connection mode, damage of remaining welding slag to a compressor can be avoided, the quality of a gas and liquid separator is effectively improved, the service life of the gas and liquid separator is effectively prolonged, and production cost is effectively reduced. On the basis, the invention further provides the gas and liquid separator with the end cover assembly and an assembly device of the end cover assembly.

Description

technical field [0001] The invention relates to the technical field of gas-liquid separation, in particular to an end cover assembly. In addition, the present invention also relates to a gas-liquid separator with the end cap assembly and its assembly equipment. Background technique [0002] The gas-liquid separator is mainly used for the separation of gas and liquid, and has been widely used in occasions where gas-liquid separation is required. In medium-sized and large-scale refrigeration systems, the gas-liquid separator is installed between the evaporator and the compressor to separate and save the liquid in the return pipe, so that the refrigerant enters the compressor from the suction port of the compressor in gaseous form. Prevent refrigerant from causing liquid shock to the compressor. In addition, the gas-liquid separator can also be used in gas-phase demisting after the condensation cooler at the top of the fractionation tower, gas dust removal in industrial and c...
