Daily maintenance and maintenance of welding machine
05 Jul 2018
The electric welder uses the high-temperature arc generated by the positive and negative poles in an instantaneous short circuit to melt the solder and the material to be welded on the electrode to achieve the purpose of combining them. The structure is very simple, it is a high-power transformer. The welding machine can be divided into two types according to the type of output power, one is AC power; the other is DC. It is made by the principle of inductance. When the inductance is turned on and off, a huge voltage change is generated. The high-voltage arc generated by the positive and negative poles in the instant short circuit is used to melt the solder on the electrode to achieve the combination. The purpose of the welding machine can not be ignored during maintenance and maintenance. Electric welder routine maintenance 1. Check the welder output wiring specification, firm, and the outlet direction is close to vertical, and the angle with the horizontal must be greater than 70°. 2....
The use of hot melt butt welder
29 Jun 2018
1, welding preparation Welding preparation is mainly to check whether the condition of the welding machine meets the working requirements. Check whether the fasteners on each part of the machine are loose or loose; check whether the electrical circuit connection of the whole machine is correct and reliable; check whether the hydraulic oil in the hydraulic tank is sufficient; confirm the match between the power supply and the input requirements of the machine; if the heating plate meets the requirements (whether the coating is damaged); trial operation of milling cutters, oil pump switches, etc. Then install the slip with the same pipe size into the rack; set the temperature of the hot plate to the welding temperature (the welding temperature of the polyethylene pipe is 200~230°C). Before heating, wipe the hot plate with soft paper or alcohol. The surface, but be careful not to scratch the PTFE anti-stick layer. 2, welding Welding shall be performed in accordance with the parameters of ...
Introduction of hot melt butt welder
09 Jun 2018
Hot melt butt welding machine is a kind of special welding equipment that uses hot melt butt welding technology to weld thermoplastic pipe fittings. The welding frame of the hot melt butt welding machine is separated from the operating system. The whole machine (automatic type, hydraulic semi-automatic type) consists of hydraulic operation console, welding frame and fixture, electric heating plate, electric milling cutter and other parts. Manual type no hydraulic system. The welding frame adopts high-strength aluminum alloy material, which has a firm structure, light weight and durability. The welding frame adopts the compression structure of the card mica sheet to accurately position the pipe and make it easy to adjust the misalignment amount. The form of hot-melt butt welding machines is various. Users should select them according to the specifications of welded pipes, their own economic ability, the quality of operators, and the management level of welding machines. According to the...
About Welding Equipment Industry Status and Market Prospects
03 Apr 2018
With the modernization of industry forward, the domestic market demand for welding and cutting equipment increased year by year, in addition to foreign countries as there is already a lot of welding and cutting equipment is being used, so the CNC plasma cutting machine popularity subject to certain constraints, and our welding and cutting equipment technology and applications start late, forming a gap between supply and demand, leading to huge of welding and cutting equipment, particularly CNC plasma cutting machine is a potential market. According to statistics, in recent years, China's annual demand of about 50,0000units of welding and cutting equipment, and there are growing year by year trend, the economic development of the surrounding area and for us to show a good international market prospects. Current trends Welding equipment should be developed fully automatic, multi-function, high-power and high quality, such as orientation. 21 century, China's welding and cutting equipment ...
What are the main pipe welding machine use?
03 Apr 2018
The so-called pipe welding machine is installed in the pipeline for the time being used, pipeline products now on the market is more and more, and each has its own characteristics pipeline, pipeline products in the market the role played is not small, the same in life, and it was their kind of product demand, when the process pipe welding machine on the market development in general are more promising, the only way to better pipe welding machine based on the market, but also be able to compare the firm. 1 pipe installation In its pipeline installation is needed when welding machine blew help, this time is a kind of pipe welding machine tools, when people in the course of its pipeline installation is very need to use pipe welding machine , because this type of product on the market has been regarded as a relatively mature product, and for the people who choose to install a new product is more risky, they still need the help of the old brand, for pipe welding machines for pipe installati...
Prospect and forecast of development of machinery industry in China
04 Aug 2016
In 2010, the raw materials market is in reasonable level, which creates a good external environment for the development of machinery industry.. 2011 is expected to inflationary pressures still larger, the raw material is the focus of the machinery industry's attention.With the gradual recovery of the world economy, the demand for basic raw materials increases, the long-term trend of rising raw material prices is irreversible. But because of the machinery industry of steel, copper, aluminum, and silicon steel sheet, etc mainly raw materials demand large and larger proportion in the cost of products. Therefore, the industry of the changes in the prices of raw materials more sensitive, especially weak capacity of raw material price fluctuations, China Machinery Industry Federation suggested that the relevant departments to increase the intensity of macroeconomic regulation and control, to maintain stable prices of raw materials. At the same time, there is a trade deficit pressure. First, ...
