Classification and selection of hydraulic wrench: At present, there are mainly two kinds of hydraulic wrench on the market: drive type hydraulic wrench and hollow type hydraulic spanner. The drive type hydraulic spanner uses high-tech aerospace materials and ultra-high titanium alloy steel casting, so it has the characteristics of high strength and strong toughness. The [...]
How to use the bolt hydraulic wrench underwater? The water pressure in the deep sea is very high, and the pressure increases by one atmospheric pressure every 10 meters. How do workers screw the bolts on the pipeline when repairing the pipeline underwater? Use steps of underwater bolt hydraulic wrench: 1. Function of wire control [...]
This article we will introduce the application and composition of hydraulic wrench. Hydraulic torque wrench, referred to as hydraulic wrench, is powered by hydraulic pressure and provides large torque output. It is a professional tool for bolt installation and disassembly. It is often used to tighten and loosen bolts larger than one inch. The maximum [...]
The selection of hydraulic wrench depends on the bolt locking and dismantling torque value, which varies with bolt diameter, material, working condition and the requirements of equipment manufacturer. In order to provide large torque for bolts, hydraulic wrench is the most ideal choice tool. Hydraulic wrench, also known as hydraulic torque wrench, is mainly divided [...]
The adjustment in using procedure of hydraulic torque wrench is the most important step, Hydraulic torque wrench is an industrial strength torque wrench, which can exert the powerful ability of large torque bolt head, mainly used in industrial pipeline engineering, oil drilling and other heavy industrial structures. How to use hydraulic torque wrench? 1. Installation: [...]
What is the usage of hydraulic wrench? Hydraulic wrench system is composed of hydraulic torque wrench, hydraulic torque wrench special pump, double high-pressure hose and high-strength heavy-duty socket. Some bolts are installed in a very narrow space and cannot be tightened and removed by means of an extension arm or other hammering methods. In this [...]
There are several common torque wrench unit, "Torque" should be called "rotation torque" in physics, that is, the torque produced when the object is affected by a tangential force with the rotation direction of the object. It is usually measured by torque wrench, torque batch, torque meter, electric batch torque tester and bottle cap torque [...]
It's the same equipment for removing bolts. What's the difference between bolt stretcher and hydraulic wrench? Bolt stretcher and hydraulic wrench are important tools for fastening bolts. They are frequently used in construction, maintenance and repair of shipbuilding, petrochemical, construction, power, mining, metallurgy and other industries. They are very important equipment for the installation and [...]
The hydraulic wrench's coarse and fine tooth is divided by the ratchet and pawl. The single teeth engaged by the ratchet and pawl are called coarse teeth, and the multi teeth engaged are called fine teeth. The two structures have their own advantages and disadvantages. We carefully understand hydraulic wrench's coarse and fine tooth advantages [...]
The failure of the hydraulic wrench pressure reducing valve may be because the pressure is too high or lower than the relief valve, or it may be because of unstable pressure. Hydraulic wrench is a tool that is in great demand at work now. With the advantage of "accomplish a great task with little effort [...]
