Hydraulic wrenchis a simple machine, the use of barre principle production and use, the ordinary wrench can not fully meet the needs of today's industrialproduction, so the hydraulic wrench was born many years ago,the structure and principle of the hydraulic wrench do you know?
Hydraulic wrench is not the full name of this machinery, its full name should be called hydraulic torque wrench,this wrench is generally composed of a combination of a number of components, is the combination of the entire suite, generally including the wrench itself, with the use of a special pump station and dual high-pressure hose and very high strength of the heavy duty sleeve, several structures can be used in combination to normally play the function of the hydraulic wrench. The specialpump has two driving methods, electric and pneumatic two ways.
After the special hydraulic pump opens and starts to work, the pressure will be generated by the motor rotation,and then the hydraulic oil is transmitted to the piston rod of the wrench through the hydraulic tubing,and then the piston rod indirectly drives the drive shaft to tighten or loosen the operation.
The structure of the hydraulic wrench itself is composed of three parts, the oil cylinder, the transmission component and the wrench body. The cylinder can output power, the piston rod and the transmission part are combined to form a sportswear, the distance between the center of the cylinder and the center of the transmission part is the arm force of the wrench to scale large, according to the lever principle calculation,the output force of the cylinder multiplied by the arm length is the theoretical value of the output torque.
As the power component of the hydraulic wrench, it belongs to the high pressure pump, the high pressure can reach 70 mpa, the above mentioned he has two power forms of electric and pneumatic pressure pump.The pressure pump consists of four parts, including motor, pump, pipe, and electrical control. Secondary pumps and pumps are generally used during operation. Among them, the pump mechanism is diverse,and the most typical pump is the plunger pump, which has four low pressure, two medium pressure and high pressure, and the medium high pressure plunger is a small diameter.
The pressure of the hydraulic wrench piston is generally controlled in the medium pressure state during operation. The total pressure flow curve is drawn, and the pump speed is higher than the secondary pump, about two times.
The general structure and working principle of hitorck hydraulic wrench is as mentioned above, compared with the general wrench, the hydraulic wrench has higher efficiency, so the hydraulic wrench is more used in the production, saving time and effort. I hope the introduction of hydraulic wrench in this article can help you.
