There are many big machines around, and we all know that there are many small parts in the machine. One of the humble small parts is called hydraulic nut, which is really indispensable. Today, Bian Xiao will talk to you about hydraulic nuts.

Hydraulic nut is not a small appliance. Simply put, it is a machine part made of ordinary steel, which is often used to pre-tighten the bolts of mechanical parts and lock some mechanical parts. In addition to pre-tightening, the hydraulic nut can also be used as a disassembly tool to connect the hydraulic interference, or to install or disassemble the conical shaft. Especially in large-scale mechanical engineering, if we want to improve work efficiency, we always need the help of hydraulic nuts.

The working principle of hydraulic nut is mainly to use the piston thrust generated by high-pressure oil pump to push the hydraulic oil in the nut to complete the installation or disassembly of the shaft. The use of this tool not only speeds up the working time, but also makes the work more accurate and safe.

Installation of hydraulic nut?

1. Prepare the hydraulic nut, screw in the workpiece, then lock the nut, and pay attention to that the pressure ring of the hydraulic nut is fixed in place.

2. Insert the oil injection interface of the manual pump into the oil injection port of the hydraulic nut, lock the handle of the unloading switch on the right side of the manual pump, and then slowly pressurize it to deflate the deflation cover on the oil drain joint until the air in the nut is exhausted. ?

3. When the air in the nut is released, unscrew the discard cap outward, close the one-way valve, and then pressurize the oil to make the pressure ring of the hydraulic nut press outward. When the pressure reaches the required pressure, loosen the handle of the unloading switch and the pressure connector of the manual pump to complete the installation. ?

Hydraulic nut is actually a bolt assembly method, which is very suitable for the fastening of heavy machinery, so hydraulic nut is often used in metal industry and hydraulic lock industry, or for the installation and disassembly of propeller and rudder shoe. There are also some mechanical wheels and gear disassembly and so on. Due to the technical research of hydraulic technology, hydraulic nut can lock the bolt in a narrow space and minimize the load space. We can also use hydraulic nuts to stretch multiple bolts together, so that the force is uniform, thus completing the load balance.

Today, Bian Xiao's hydraulic nuts are introduced here. I hope I can understand and help you. Please pay attention to the decoration of Tuba rabbit about hydraulic nut.
