Abstract
The welding method of the liner cylinder and the outer cylinder of the iron removal filter comprises the following processing steps: 1) drilling through holes with the diameter of phi 10 at four corners of a square with the diameter of 300mm multiplied by 300mm on the lining cylinder body, and removing burrs; 2) spot welding is carried out after the assembly according to a process diagram, manual electric arc welding is adopted for spot welding, and the polarity is reversed; 3) the first layer of welding adopts manual electric arc welding, and the polarity adopts reverse connection; 4) the second layer of welding adopts automatic submerged arc welding, and the polarity adopts reverse connection; 5) and carrying out PT nondestructive testing and air tightness testing on the welding seam. The invention has convenient operation and greatly reduces the production cost. The invention is used for the iron removal filter.
Description
Technical field
The present invention relates to deironing filter, particularly relate to the welding method of deironing filter liner cylindrical shell and outer cylinder body.
Background technology
Deironing filter is the corollary equipment for condensate system, and install the filter element of some in filter, water is entered by each filter element outside, flows out by the antipriming pipe at filter element center, and impurity is trapped within filter element surface.In general condensate polishing system, the installation site of deironing filter is after condensate pump, so deironing filter system pressure is higher.Therefore traditional deironing filter material adopts composite plate; Composite plate is expensive, is that general medium-sized and small enterprises all do not afford to do in the manufacturing and purchase use, so there is a lot of enterprises sewage to can not get timely process, contaminated environment, injures the healthy of people.
Summary of the invention
Object of the present invention will provide a kind of easy to operate exactly, can reduce the deironing filter liner cylindrical shell of production cost and the welding method of outer cylinder body.
The object of the present invention is achieved like this: the welding method of deironing filter liner cylindrical shell and outer cylinder body, it is characterized in that: comprise following procedure of processing: 1), on liner cylindrical shell on every tetragonal corner of 300mm × 300mm, drill diameter is the through hole of Φ 10, and removes burr; 2), by tack welding after process chart assembling, tack welding adopts manual electric arc welding, and polarity adopts reversal connection; The packing material trade mark is: A302; Diameter is: ¢ 2.5; Electric current is: 80-85(A); Voltage is: 22-23(V); 3), ground floor welding adopts manual electric arc welding, polarity employing reversal connection; The packing material trade mark is: A302; Diameter is: ¢ 2.5; Electric current is: 80-85(A); Voltage is: 22-23(V); Speed is: 12-13(cm/min); 3), second layer welding adopts Lincoln weld, polarity employing reversal connection; The packing material trade mark is: A302; Diameter is: ¢ 3.2; Electric current is: 100-110(A); Voltage is: 22-23(V); Speed is: 15-16(cm/min); 5), butt welded seam carries out PT Non-Destructive Testing and air-tight test.
Liner cylindrical shell employing material of the present invention is: 06Cr19Ni10; Described outer cylinder body employing material is: Q345R.
The present invention is easy to operate, significantly reduces production cost.
