Explosion-proof wrench tool use place

The tool material is made of beryllium bronze and aluminum bronze. The beryllium bronze alloy and aluminum bronze alloy do not generate sparks when impacted or rubbed. They are suitable for manufacturing tools used in explosive, flammable, strong magnetic and corrosive situations. The BeA-20C alloy withstands the impact energy of 561IJ in 30% hydrogen or 6.5-10% methane air oxygen. There are 20 impacts without sparks and combustion.

The material of the tool is copper alloy. Due to the good thermal conductivity of copper and the characteristic of almost no carbon, the heat generated in a short time when the tool and the object are rubbed or impacted is absorbed and conducted. Another reason is that the copper itself is relatively soft. , It has good retreat during friction and impact, and it is not easy to produce tiny metal particles, so we can hardly see sparks, so the tool is also called non-sparking tool.

The tool should not be used arbitrarily as an ordinary tool in non-hazardous places, so as not to lose its due performance.

The training items of the socket mainly include the training of the size of the socket, the training of the general situation of the socket, the training of the matching accuracy of the socket, the detection of the socket wrench and the torque test of the socket. Among them, if the sleeve size training method is to be honed with general measuring tools and full-shape measuring tools, the size shortcomings of the sleeve should be defined in accordance with the national standard.

The second is the honed of the sleeve profile. The profile test mainly includes the profile quality of the sleeve and the roughness of the profile. For example, the inner and outer profile of the sleeve should not have defects such as cracks and scars that affect the operating function, hexagon or ten. The corners of the two corners are clear.

The matching precision of the sleeve is honed. The method of this test is to insert the square tenon of the sleeve attachment into the adjacent square hole 5 times in a row, and then lift the square tenon sleeve to prevent it from falling off. The various parts of the sleeve must be very carefully and intimately matched, and the assembly and disassembly should be innocent. The anti-dislocation beads and anti-dislocation pins of the copper alloy should not fall off.

Due to the performance of tool materials, tools are widely used in petroleum refining and petrochemical industry, coal mines, oil fields, gas chemical industry, gunpowder industry, chemical fiber industry, paint industry, fertilizer industry, and various pharmaceutical industries. Petroleum tankers and liquefied petroleum gas vehicles, airplanes, warehouses dealing in flammable and explosive products, electrolysis workshops, communication machine assembly workshops, places where tools are required to be rust-proof and anti-magnetic, etc.
