Digital display torque wrench

digital display torque wrenches spanner just as its name implies is with digital display torque wrench, torque wrench, torque wrench, it is different from the average torque wrench, has a strong operating functions, include torque setting; Unit set; Set pattern; Value is stored; Numerical cleared; Numerical output correction function and network, digital torque wrench, chrome vanadium steel quality. It is the highest one of the torque wrench, hydraulic bolt tensioning equipment reaches the set value can not only when, wrench "card tower" noise or wrench joint bending Angle, but also through digital display or LED lights to prompt the user, but also on the set of torque can be done through buttons and digital display, more convenient than the digital display torque wrench and easier operation. In all digital display torque wrench is the most easy to operation, torque wrench it by installing digital display screen reduces the requirement to the operators

hydraulic flange spreaders

hydraulic flange spreaders are powered by hydraulic, providing high torque output, professional installation and disassembly of the bolt for bolt tightening tool is often used to tighten and remove loose bolts greater than one inch.
Hydraulic torque wrench is made up of head, hydraulic pumps and high pressure tubing.High pressure tubing, hydraulic pump transfers the power to head drive head nut tightened or loosened.Hydraulic pump can be powered by electricity or compressed air.hydraulic flange spreader work is composed of three parts, the framework (also known as the shell), fuel tank and transmission components.Cylinder output force cylinder piston rods and transmission parts joints, cylinder to the transmission part is the distance from the Center is strong arm hydraulic wrench, cylinder output multiplied by the arm, is the theory of hydraulic wrench torque due to friction, hydraulic wrenches actual output torque is less than the theoretical torque.

torque wrench calibration tool

When the piston torque wrench calibration tool work, and generally is in the 10-32MPa State, and pressure flow is high pressure (32-70MPa) flow rate 2.2 times, integrated three-level pressure and flow curves, three-stage flow speed is the secondary flow of the pump pump nearly twice times.Three-level torque wrench calibrators pumping speed is much faster than the secondary pump.

Electro-hydraulic wrench consists of brushless motor and pump motor carbon brush motors.Brushless motors are usually induction motors, need a capacitor.In order to pump to start with pressure, need to install the start capacitor running capacitor.Brush motor is series motors, high speed, can provide a larger pump flow, but more noise and vibration.
Brushless motors are often used for tens of thousands of hours, brush motor life and hundreds of more than more than 1000 hours of continuous operation, reach the limit you need to replace the carbon brushes, or is likely to cause bearing wear.

Considerations for hydraulic bolt tensioners

1) a type of hydraulic bolt tensioners, can only solve several similar bolt sleeve with 3-4;
2) manufacturers have a condition it is best to first use of an electric pump with two wrenches, diagonal, you can improve efficiency, torque is more accurate, one for four costs are too high;
3) flange alignment must be someone special custody, regular maintenance, such as oil changes, cleaning and so on;
4) bolt torque standard should refer to national standards, national standards are in line with China's national conditions.

torque wrench calibrators power unit folded edit this paragraph

torque wrench calibrators are hydraulic wrench power unit, providing high pressure hydraulic oil for hydraulic wrench powered hydraulic wrench is the unit of execution in a hydraulic system.Hydraulic wrench pumps belonging to the high pressure pump, the maximum working pressure of 70MPa, common with electro-hydraulic pump and hydraulic pump.dial indicating torque wrench by the motor (electrical or gas motors), pumps, piping, electrical controls and other components.Pump common pump two and three stage pumps, generally the secondary pump is a gear pump with low pressure and high pressure piston pump.Gear pumps for pump provided with hydraulic oil, gear pumps and pump for pressure up to 7-10MPa.The diversified structure of the three-stage pump, typical structure of all piston pump, low pressure 4 large diameter piston, 2 small piston diameter, high pressure 2 small diameter piston.Three pumps using a pump to gear pump, two-level and three-level pumping for piston pumps.Triplex pump level, second level, three levels are called low pressure, medium pressure and high pressure.

Type safe operation of dial indicating torque wrenches

In most began of people began to first do of is to determine dial indicating torque wrenches split pine of action, also is is we also to using of is used to lock tight nut then in through the by Xia this action or spin out lock solid screws then in for some of out drive party axis in for on they of reversing, in later we can in it of above loaded Shang some about of drive party axis positioning device, pulled Xia reaction arm lock solid device, by for azimuth loaded into reaction arm, and split pine, and lock tight work Shi party axis direction.In the second step we can pump station it used to make the connection, but then we can the hydraulic torque wrench chart high pressure outlet and high pressure of the hydraulic wrench imports where there is low pressure at the pump outlet hydraulic wrench with low voltage inlet using the high pressure fuel pipe connecting their role.When we connected it but we need quick connector on the connection tubing then we should be inserted in the end of this, then we can hand tighten the retaining nut.There is, we need to use the hydraulic wrench is used when we need to carefully inspect the tubing connector is firmly seated us there is, when we use the existence of oil in the pump.Can we use to connect the power plug of the pump well.When we use the need to place the wrench in our yard.In the next action is needed to open the pump power switch, then we are going to start the pump and check that the pump is working properly before it can be used

Characteristics of hydraulic bolt tensioners
