Explosion-proof tools

Explosion-proof tools Explosion-proof tools are made of copper alloy. Due to the good thermal conductivity of copper and the characteristics of almost no carbon, the heat generated in a short time is absorbed and transmitted when the tool and the explosion-proof tool body rub or impact. Another reason is that Because copper itself is relatively soft, there is a good concession in friction and impact, and it is not easy to produce tiny metal particles. Therefore, we can hardly see sparks. Therefore, explosion-proof tools are also called non-sparking tools. The material of explosion-proof tools is made of beryllium bronze and aluminum bronze. Beryllium bronze alloy and aluminum bronze alloy do not produce sparks when they are impacted or rubbed. They are very suitable for use in the production of explosive, flammable, magnetic and corrosive applications. tool. The BeA-20C alloy withstands 561IJ of impact energy in 30% oxygen or 6.5-10% methane air oxygen. There is no spark and combustion in 20 times. The main scope of application is: petroleum refining and petrochemical industry, coal mine, oil field, natural gas chemical industry, gunpowder industry, chemical fiber industry, paint industry, fertilizer industry, various pharmaceutical industries. Oil wheels and liquefied petroleum gas vehicles, aircrafts, warehouses that operate flammable and explosive materials, electrolysis workshops, communications equipment assembly workshops, places that require tools that do not rust, wear resistance, and magnetic resistance. Aluminum-copper alloy explosion-proof tools are made of precious rare metals for synthesis, smelting, and forging. Face hardness HRC25 ° above, tensile strength δb> 75-85kgf/mm, all other technical indicators have reached the advanced level of similar foreign products. The continuous use of flammable gas ethylene (concentration of 7.8%) ensures safety, and no spark, explosion, friction, and drop hammer are generated.

Explosion-proof tools Category:

Explosion-proof tools internationally collectively referred to as "safety tools" and "non-sparking tools", the domestic collectively referred to as "explosion-proof tools." Explosion-proof tools that are produced, sold, and circulated in China can be divided into two major categories: 1. Aluminum-copper alloy (commonly known as aluminum bronze) explosion-proof tools, the specific material is based on high purity electrolytic copper as the matrix by adding appropriate amount of aluminum, nickel, manganese, iron and other metals to form a copper-based alloy. 2. Beryllium copper alloy (commonly known as beryllium bronze) explosion-proof tools, the specific material is based on high purity electrolytic copper as the matrix by adding appropriate amount of niobium, nickel and other metals to form a copper-based alloy. The thermal conductivity and electrical conductivity of these two materials are very good. The hardness and wear resistance of aluminum bronze after heat treatment can reach HRC30o or more as much as that of beryllium bronze. However, the magnetic properties of aluminum bronze are slightly higher than that of beryllium bronze, but they all belong to the micromagnetic range. Both aluminum bronze and beryllium bronze can be applied. Strong magnetic environment. Explosion-proof tools can also be divided into two categories based on the manufacturing process: 1. Casting process: It is a traditional manufacturing process. It was an internationally-manufactured explosion-proof tooling process technology in the 1980s. Most of the explosion-proof tool manufacturers in China have been used up to now. Casting process advantages: simple process, low manufacturing cost. Disadvantages: product density, hardness, tensile strength, low torque, porosity, trachoma more lead to a shorter product life. 2. Forging process: the latest international manufacturing process is the use of large presses or punches, with a high heat forming mold made by one-time forging. Forging process advantages: can make the product density, hardness, tensile strength, torque greatly improved, basically eliminate blowholes, trachoma, so that the mechanical properties of the product life than the traditional casting process is about 1 times longer. Disadvantages: Large investment in equipment, equipment, and molds, resulting in higher costs. At present, domestic companies that use forging technology to produce explosion-proof tools have a few companies, including Sino-Park explosion-proof, lean explosion-proof, and Bohai explosion-proof.

The use and maintenance of explosion-proof tools 1. Explosion-proof tools have brought safety guarantees for our workers working in flammable, explosive and corrosive workplaces. This has made our social safety more perfect and also made us work. Staff are more comfortable working. After the use of explosion-proof tools in our daily work, there should be a proper maintenance phase, which is crucial to the life of the tool, because if the maintenance of explosion-proof tools is not appropriate, our tools cannot be used for a long time. We serve. First of all, we need to keep the tool in a dry place. This is to make sure that some parts of the work do not get damaged. After 20 consecutive taps in our daily work, the surface attachments of the tool should be treated, and then used after being cleaned. Do not use it continuously so as to prevent the tool from being heated due to prolonged friction. May damage our tool products. 2, after use, clean the surface of dirt and deposits, place a dry and safe place to save. 3, tapping tool products, can not be a continuous blow, more than 10 times should have an appropriate interval, at the same time to promptly remove the debris sticky parts of the product and then continue to use. 4. Wrench products must not be overpowered, and they must not be used to stretch the fasteners by using sleeves or other metal rods and hammers (except tapping wrenches). 5, cutting edge tools should be placed in the sink and gently grind the grinding wheel, not too much force and contact with the grinding wheel for too long. 6. In the actual operation of hammering tools, it is necessary to remove the oxides on the surface of the debris and the working surface to prevent third parties from hitting. Based on the above performance and use, it is shown that aluminum-copper alloys are more suitable for normal pressure equipment and environments where explosion-proof conditions are not strict (such as gas stations, small oil depots, etc.) during normal use. The applicability of the performance of beryllium copper alloy explosion-proof tools (such as oil refineries, gas conversion stations, gas recovery plants, drilling teams, etc.). 7, before using the product to remove the surface oil, use the steel tool reference manual.
