About impingement sleeve

Impact sockets with mechanical torque wrenches, are a special tool to tighten or remove loose screws, metric and imperial impact sockets points, also known as impact sockets metric and imperial impact sockets, impact sockets Although the concave shape of the same, but the diameter, length and so is the shape and size of the corresponding equipment for the design, the state is no uniform requirement, so the impact of the sleeve design is relatively flexible, to meet the needs of the public.

The difference between the two common wrench

Dial torque wrench is the use of a new type of torque measuring instruments measured intuitive fastener torque value is indicated on the dial and memory size of the torque value. There sleeve, an elastic element, amplification mechanism, some institutions and memory display of five agencies. Particularly suitable for torque indication pretension after testing verification. Digital torque wrench is the use of strain measurement principle and integrated digital processing technology, we developed a new generation of high-quality digital torque measurement tools.

Type air pump Classification

The air pump is an enclosed space, or add a device to exclude air from the closed air space. air pumps is mainly divided into electric pump, hand air pump and pump feet moving. Electric air pump is powered pump electricity, compressed air through the power constantly generates pressure; manual pump is to practicing hand-powered pump, by practicing hand kept compressed, resulting in pressure; feet move leg muscles pump is powered the pump, compressed air through the leg muscles constantly generating pressure to work.

Classification gearhead

Main features hexagon reducer has a reverse gear unit is self-locking feature, you can have a greater reduction ratio, the input shaft and the output shaft axis is not the same, nor in the same plane. But generally larger, the transmission efficiency, high precision. It belongs to the harmonic gear hydraulic torque wrench, but the latter is the use of harmonic drive controlled elastic deformation of the flexible element to transmit motion and power, small size, high precision, but the disadvantage is the limited lifetime Flexspline , the impact of intolerance, rigidity and inferior to metal parts.

Dial torque wrench before the display instructions

dial torque wrench is also called dial-type torque wrench is a tool for torque calibration service.
1, the rotary knob on the case or the case can be driven pointer rotation, the pointer is a pointer memory, called passive pointer or trailing pointer; and join the movement for the work pointer pointers, also known as the active pointer.

2, the use of this product should be used in the appropriate range of sizes and models depending on the intensity level and the requirements of the fastener torque values should not exceed the scope of use.

Flange spreader used in the heat treatment step

Flange spreader is a new kind flange spreader tool of public use lifting, usually using mechanical flange spreader, whose task is to make it and placed in the wells annealing heat treatment equipment 6-8 meters in diameter when wind power flange connection or placement hoisting breaking easy to operate and reliable. The technical program elements are: at a position below the lifting rings are provided with a hanging chain cloth cage, the lifting chain a, the lifting chain, b, c of the rear end of the lifting chain head are provided with a hook , hook b, hook c; the hook with a, hook b, hook the bottom end of the c is provided with a left hook under the vertical curved feet under hook feet toes pointing wind power flange axis position, no slippage between the upper surface of the lower hook and the bottom surface of the foot of the wind power flange.
