There are two series of hydraulic wrenches: driven hydraulic wrenches and hollow hydraulic wrenches. As the name suggests, the driving hydraulic wrench is to rely on the drive shaft to drive the corresponding specification sleeve to achieve the preload of the nut, as long as the torque range allows, according to the replacement of the corresponding high-strength sleeve to complete different specifications of the bolt, is a general-purpose hydraulic wrench, the scope of application is wide. Hollow hydraulic wrenches are equipped with a transition sleeve.

Generally, the screw is stretched out relatively long, the space range is relatively small, the double nut, the bolt spacing is too small, the nut and the equipment wall are too small, or there are many difficult working conditions in some specific industries.

Generally, there are several specifications, such as M36, M42, M48, if you don't say how big the nut is, it is according to the opposite side of the metric bolt nut sub-matching barrel, and the hexagonal side of the nut of M36 is. 55, M42 is 65, M48 is 75, if the bolt specification span is too large, and the torque span is large, then the preload of these bolts must be selected two types of plate wrenches.

The specifications of the bolt, the strength grade of the bolt is. The most critical parameters of hydraulic torque wrench selection, bolts are different, torque is different, the same bolt strength grade is different torque, the same bolt strength grade, the torque of different working conditions is also different, the bolt torque used in rolling mill equipment and chemical equipment is not the same, the general design drawing paper will give the torque size, if not given, the corresponding standard number will be given, such as heavy machinery and equipment is the use of national standard a jb, such as the torque of the bolt, for. The torque of the M42 to the bolt is 2744Nm; The torque of the M36 bolt, is.

1764nm；The torque of the bolt is 3920mm; You can choose one type of wrench for three bolts.

Bolt and nut space location.

If there is no space limitation, any type of wrench can be used, the drive hydraulic wrench is the most economical, such as the bolt is screwed after the thread is long or the bolt has limited space, it is best to use a hollow hydraulic wrench, such as the distance between the nuts is narrow, you can choose a hollow hydraulic wrench.

When you buy Wharton hydraulic torque wrench, there will be someone to tell you the specific model of the problem, the use of the absolute good, there is no reason not to recommend it, aluminum and titanium alloy material, feel very good, there are professionals to help choose the specifications of the model, people are high-tech enterprises, listed companies, reliable! There's a lot of relevant information below.

The main body of the camshaft is a cylindrical rod body of the same length as the cylinder block. It is covered with several cams that are used to actuate the valves. One end of the camshaft is the bearing support point, and the other end is connected to the drive wheel.

The sides of the cam are egg-shaped. The aim is to ensure adequate intake and exhaust of the cylinders, specifically to open and close the valves in the shortest possible time. In addition, considering the durability of the engine and the smooth operation, the valve should not have too much impact due to the acceleration and deceleration process during the opening and closing action, otherwise it will cause serious wear of the valve, increase noise or other serious consequences.

In general, in in-line engines, one cam corresponds to one valve, while in V-engines or boxer engines, one cam is shared for every two valves. Rotary engines and valveless valve-free engines, on the other hand, do not require cams due to their special structure.

Camshaft wear mainly includes: shaft bending, journal and bearing, as well as cam profile and height wear.

The reason is mainly due to the slender structure, the small contact area between the cam and the tappet in the work, the large unit pressure and the high relative sliding speed.

To test the bending of the camshaft, the front and rear journals of the shaft can be placed on a V-shaped iron with a flat plate underneath, and then the swing difference of the intermediate journal can be measured with a dial gauge.

When the allowable value is exceeded, a cold press correction should be performed. The inspection of cam wear is to measure the distance between the center of the cam center and the base circle on the back and the diameter of the base circle with a micrometer, and determine the degree of wear (generally more than 8 mm) by the difference between the two.

If the difference is less than the allowable value, the valve opening will be reduced, the power and economy of the engine will be reduced, and the camshaft should be replaced.

To make the hydraulic wrench need torque during use, follow the steps below to set the pressure of the hydraulic pump of the hydraulic wrench.

Loosen the handle on the hydraulic wrench in a counterclockwise direction so that the hydraulic pressure reaches zero.

Turn the rotating handle on the hydraulic wrench in a counterclockwise direction and release the control valve.

Press the button on the hydraulic wrench to make the motor work.

Press and hold the green button without letting go, and turn the handle clockwise.

When adjusting the hydraulic pressure, modulate from the lowest number to the desired value. When adjusting the value, be sure to start from low to high, if it is in the opposite direction, the value will not be very accurate. If the value is adjusted incorrectly, adjust the value below the set value and then adjust it again.

Release the green button to adjust to the exact pressure value, then press the red button and readjust if the value is inaccurate.

At the end of each job, the pressure of the regulator should be adjusted to zero.

1.The piston does not jack or retract.

The quick coupling is not connected to the place——— check the quick coupling, make sure the quick coupling is connected to the end, the quick coupling is defective——— replace any defective quick coupling remote control is defective——— replace the button or controller.

2.The piston does not retract.

The return pipe is not properly connected——— the return pipe is safely and correctly connected, and the return pin or spring is damaged——— replace the spring or pin.

3.The cylinder cannot build up pressure.

Replacement of any defective seal fitting ——— any defective seal fitting in case of piston seal leakage ——— replacement of any defective fitting.

4.The square head drive shaft does not rotate.

Oil or dirt is present between the ratchet and pawl——— disassemble the ratchet parts, wipe the dirt or oil stains, the ratchet or pawls are worn out or damaged——— replace any worn or damaged parts5The pump does not build up pressure.

Defective pressure relief valve ——— check, adjust or replace the pressure relief valve voltage is too low ——— ensure that the current, voltage and some other values meet the operating requirements of the pump, the pressure gauge is defective ——— replace the pressure gauge.

6.The nut rotates with the return stroke.

The ratchet and detent pawls do not coincide——— the pawls are replaced or the pressure springs of the pawls are replaced.

Torlke hydraulic torque wrenches are available in two series: driven hydraulic torque wrenches and hollow hydraulic wrenches. The driven hydraulic torque wrench is used with a standard socket and is a universal hydraulic wrench with a wide range of applications. The thickness of the hollow hydraulic wrench is thin, especially suitable for places where space is relatively tight.

It is suitable for electric power (nuclear power, wind power, hydropower, thermal power), shipbuilding, metallurgy, transportation, cement, construction, aviation and other fields.
