How does a hydraulic torque wrench work?
Hydraulic torque wrenches are widely used in construction, maintenance, and emergency repairs in petroleum, chemical, electric power, mining, metallurgy, shipbuilding, cement, heavy equipment manufacturing, and other industries. According to relevant statistics, 50% of equipment failures are caused by bolting failure, and reports of equipment accidents caused by a bolting failure also occur from time to time; In the process of equipment installation and maintenance, hydraulic wrenches must be used for the installation and removal of large-sized bolts. It is not only simple and convenient to use, but also provides very accurate torque, with a torque accuracy of ±3%, which is impossible to achieve manually. How does a hydraulic torque wrench work? A set of hydraulic torque wrench tools is composed of a hydraulic wrench, a hydraulic torque wrench pump, a high-pressure hose (safety factor 4:1 ), and a hexagon reducer (or impact socket). The hydraulic wrench is composed of the body (also called the shell), the drive unit(hydraulic cylinders), and the transmission parts(ratchet and driveshaft). Before using the hydraulic torque wrench pump, fill 46# anti-wear hydraulic oil into the oil tank, and turn on the power to start the pump station, the pump station will generate pressure through the operation of the motor, and It is transmitted to the
Hydraulic Cylinder Leaks (And How to Fix them)
What is a Hydraulic Cylinder, and How does it work? A Hydraulic Cylinder is a mechanical actuator, designed to carry a Hydrostatic force in a single direction. Commonly used in construction equipment, civil engineering, and machinery designed for the manufacturing process. A hydraulic cylinder uses any form of hydraulic fluid, typically oil, that is pushed back and forth by a piston into each side of the cylinder. This enables the linear motion to work, making machines such as Bulldozers and tractors carry out movements such as breaking down buildings or heavy lifting that cannot be done through human force. Hydraulic cylinders consist of a piston rod, a piston seal, and two separate regions, all nutted and bolted together to exert the force of hydraulic fluid within the cylinder tube. A hydraulic cylinder exerts massive amounts of force, anywhere from several kilograms, to a couple of thousand tonnes! Whatever linear motion you need automating, a good quality hydraulic cylinder is the perfect solution for any manufacturing, farming, civil engineering, or automation company’s needs. What Causes Hydraulic Cylinders to Leak? A common problem for high-load engineering and manufacturing companies is working out ways to minimize leakages from their hydraulic cylinders. Leakages in
Bolt Tensioning vs Torquing: Introduction, difference, pros, and cons.
Introduction Bolt tensioning and torquing are two different ways to adjust the tension on a bolt. Torque is the ability to apply a rotational force and is used to tighten and loosen bolts, while bolt tensioning is when the bolt’s nut is tightened against the head of the bolt. This tightening creates a drag on the bolt, increasing its stability and preventing it from loosening during use. Torque wrench use generally depends on the size of the bolt, while tensioners can be used with almost any bolt size. What is bolt tensioning? Bolt tensioning is the process of adjusting the tension on a nut or bolt by using a hydraulic press force. This is done to precisely adjust the strength of the connection between the parts being joined. The process can tighten or loosen connections, and it is an often-needed procedure in many industries. Hydraulic bolt tensioners are an essential part of modern machinery, as they allow for accurate and repeatable adjustment of bolt tension. What is bolt torquing? Bolt torquing is the act of tightening or loosening a bolt by turning it with a wrench. It’s an important part of industrial maintenance, and it can be done by hand or using a torque wrench. Torque is measured in
How do you bleed air out of a hydraulic hand pump
You bought a new hand pump but found that the hand pump does not suction oil when it is working. Even if you press the handle of the hand pump repeatedly, the hand pump starts to suction oil, and the oil intake is much less than normal. Please don’t worry, this is because there is a shortage of oil inside the fuel tank of the manual pump and it has not been used for a long time, and air has entered the inside of the plunger of the manual pump. At this time, we need to bleed the air inside the plunger, and the manual hydraulic pump can work normally. Let’s take a RIVERLAKE P-462 two-speed hydraulic hand pump as an example, in order to completely expel the air inside the hand hydraulic pump plunger, please follow the steps below: 1. Fill the manual pump oil tank with hydraulic oil, connect the manual pump, hydraulic hose, and hydraulic cylinder 2. Turn the air release valve clockwise to open the air release valve 3. Rotate counterclockwise to loosen the air release screw of the plunger, turn on the manual position valve of the manual pump, and press the handle repeatedly to discharge the air inside
