Xicheng EP LTD is specialized in PP anti-corrosion processing equipment, professional CNC machining equipment and roll forming machinery, PP anti-corrosion equipment design, processing, installation services, the main products are PP spray tower, PP tank, PP activated carbon adsorption box, etc., this paper mainly talk about how PP plate processing PP tank.
First of all, the need to draw, according to the user demand through AUTO CAD drawing software, draw the PP water tank shape size, length and width of high data, here we should pay attention to the bottom plate and top plate of the PP water tank according to the specification needs to be out of the edge, that is, to set aside welding space, universal environmental protection in accordance with the specification set aside about 40mm space.
Second, to pay attention to the actual volume and the thickness of the PP tank, some customers are given size requirements, the internal dimensions of PP tank, so the drawing will be deducted when the thickness of the PP board, if the customer is given volume requirements, clear is the actual volume or volume, customers are given for the effective volume, so in the design of PP tank, Often want to enlarge a little, set aside 5% space, of course, still want to consider the shape size, some customers rated installation space, shape size is big, can not put in.
Finally, the customer needs to determine the drawings, drawings no problem can be made, then how to process PP PP water tank PP board, is a matter of production. After the production workshop gets the picture, if it is a square PP water tank, it needs to be fed first, because it needs to be opened by the engraving machine, the size should be accurate, and the position of the four side plates should be taken into account, and the long side is short side or short side. Secondly, pay attention to the elevation of the opening, such as: a side to install DN25 flange, then this hole in the carving opening, to open 32mm, because the outside diameter of DN25 pipe is 32mm.
After cutting, then there is the joining together of PP tank, according to the drawing requirements splicing after forming, adopting PP welding torch sector mouth, USES the high spot welding, hold the shape, only can be used in a triangular welding rod welding, according to the technological requirements, decided to electrode type and welding method, are mainly flat electrode, triangle electrode, welding methods mainly include conventional welding, welding two blow, Usually the water tank for atmospheric pressure, the use of conventional welding, such as with pressure, need to blow welding, mainly considering the strength of PP water tank.
PP tank after forming, it is necessary to strengthen the tank, to strengthen the way has two kinds, a kind of to strengthen inside, inside the water tank, welding tic-tac-toe frame welding, another for external strengthening, the flange, hoop and channel steel tank, reinforce PP tank strengthen way depends on the design, design to strengthen the purpose is to increase the strength of the tank.
PP water tank after strengthening, the back of the work is welding flange, PP plastic flange need to pay attention to the length, and strengthen the way, part of the flange need to have a certain bearing function, such as: the installation of the level gauge, there is a certain weight, completely stressed on the flange, at this time, the PP flange triangle support to strengthen processing.
After PP water tank production is completed, pan-pu environmental protection needs to spend a certain labor cost, to the appearance correction, wipe clean, clean up the tank internal garbage, do the water experiment, to ensure that no leakage, can be arranged for delivery.
The above process is from PP sheet how to process into PP water tank of the whole process, pan pu environmental protection specializing in PP water tank processing services.
