Share the daily maintenance and use precautions of the dual-purpose wrench
In our daily life, the most commonly used wrenches are ordinary wrenches or torque wrenches, but in industrial production, ordinary wrenches are not so powerful. In many priority areas, more specialized wrenches are needed. , a dual-purpose wrench is such a type of wrench, it plays an important role in petroleum, chemical, metallurgy, power generation, oil refining, shipbuilding, petrochemical and other industries, and it is also an important tool in equipment installation, equipment and equipment overhaul and maintenance work. A must-have tool, the dual-purpose wrench is divided into two types: metric and inch.The dual-purpose wrench is integrally forged from high-quality medium carbon steel or high-quality alloy steel. It can be seen that its material is quite satisfactory, which also shows that its advantages are extremely significant, with reasonable design, stable structure, high material density, and impact resistance. Strong, non-folding, continuous, non-bending, high dimensional accuracy and durable, these advantages make the dual-purpose wrench firmly occupy a place in industrial production and manufacturing and maintenance.
Although the advantages are significant, there are some things that we need to pay attention to when using a dual-purpose wrench:
Do not use metric spanners for inch bolts or nuts, nor use inch spanners for metric bolts or nuts, so as not to cause slippage and injure the user;
Do not add a sleeve to the end of the wrench to extend the force arm to prevent damage to the wrench;
Do not hit the wrench with a steel hammer, as the wrench is easily deformed or damaged under impact load.
Under normal circumstances, the service life of these tools will be guaranteed if the maintenance work is done well. For example, the ratchet dual-purpose wrench needs to be removed after every 3,000 times of disassembly and installation of screws. After the drive shaft is taken out and wiped clean, apply butter to lubricate the ratchet set, and then assemble the ratchet back after lubricating; if it is too troublesome to record the number of times, regular maintenance is also feasible.
