the Features of impact socket set

Although the concave shape of the impact socket set the same, but the outside diameter, length and other equipment for the corresponding shape and size of the design, the state is no uniform requirement, can be used with a wide range of torque wrenches with, so the impact of the sleeve design relatively flexible, to meet the needs of the public.
First, the use of advanced chrome - molybdenum steel, more resistant to wear, long life
Second, forging molding, reasonable hardness, high impact resistance
Third, through multiple heat treatment process, the organization is reasonable, uniform hardness
Fourth, high precision, reduce screw wear

Torque screwdriver functional principle

torque screwdriver is also called torque screwdrivers, popular understanding is that there screwdriver torque value. There are two main preset torque screwdrivers, Analog (dial) torque screwdriver commonly used. When the preset torque screwdriver can be preset torque value, when the fastener is screwing torque reaches a predetermined value, the screwdriver inside the automatic clutch is disengaged, issued a "despair, despair, despair ..." sound, and this action can be felt by hand. In this case, even if the operation was continued urging, will not exceed the limit set in advance. Coupling quality torque screwdriver fasteners directly affect the various instruments, using quality electrical and
mechanical equipment, household appliances and other products to the reliability of these products.

Hydraulic torque wrenches classification

Hydraulic torque wrenches have driven hydraulic wrench and hollow hydraulic wrench two series. As the name suggests, the drive hydraulic torque wrenches are driven by the drive shaft corresponding specifications impact socket set to achieve preload nut, lower torque range as long as the circumstances permit, according to replace the corresponding sleeve high strength bolts to complete different specifications for general purpose hydraulic wrenches, a wider scope. Hollow hydraulic torque wrench is equipped with a transition sleeve use. Generally screw sticking out a long, relatively small spatial extent, double nut, bolt spacing is too small, nut and equipment wall is too small, or more difficult conditions some specific industries.

Hydraulic Nut Splitters

Hydraulic Nuts Description:
Locking and separation is the common thread of torque generated by the rotation torque wrench to use the friction between the locking screw and separation. For large diameter threaded connection, affected manpower, tools and work space, its preload failed to reach the design requirements, so it is easy to loose the vibration occasions. Hydraulic Nut Splitters completely changed the traditional way of tightening the locking torque axial tensile locked by means of ultra-high pressure pump power, the threaded screw axially elongated elastic material itself will use thread lock so the hydraulic nut has a very high capacity and unique preload can synchronize multiple sets of bolt tightening achieve the same preload notable feature gradually been widely used in various industries. Hydraulic nuts are mainly used frequently disassembly or axial top tight bolted on various occasions, preload and locking requirements, and as a hydraulic interference fit coupling disassembly tools.

The Use notes and Caution of hydraulic jack

Hydraulic jacks Caution:
1. When using a hydraulic jack, you should first try to jack up the first part of the weight, carefully check the hydraulic jacks without exception, and then continue lifting heavy objects. If it is found after the compression plate is not flat, not solid or hydraulic jacks tilt
2. Be sure to return the hydraulic jacks relief, after timely deal before operating again.
3. In the lifting process, should be at the bottom of the hydraulic jacks Insurance sleepers bedding planes with increasing weights to prevent hydraulic jacks tilt or cause a sudden drop in the piston and causing the accident, should be gradually withdrawn when the decentralization of heavy sleepers out, the distance between the sleepers and heavy sleepers shall not exceed the thickness of the piece, to prevent accidents!
4. If the weight exceeds the lifting height required hydraulic jacks rated highly, you must first hydraulic jacking weights underlying good sleepers, lowered hydraulic jacks, padded bottom, repeated lifting, until the desired lifting height
5. Hydraulic jacks can not be used as a permanent bolt tensioner tool. For a long time support, should increase support portion beneath the weight, in order to ensure that the hydraulic jack from damage.
6. If lifting weights with only one end of a hydraulic jack, hydraulic jack should be placed on the axis of symmetry of the weight, and hydraulic jacks consistent base length direction and the direction of the weight and easy dumping. If the heavy end of the use of two hydraulic jacks, and the direction of the base should be slightly splayed symmetrically placed on both sides of the axis of symmetry weights.
7. Use two or more hydraulic jacks simultaneously lifting operations shall be unity of command, coherence, while lifting.
8. A hydraulic jack should be stored in a dry, dust-free place, unsuitable for acid-base, workplace corrosive gases, but not on the outside sun and rain!

Features bolt tensioners

Bolt tension elongated bolt directly using pure tension, shear and lateral force without twisting, to join the contact surface without friction damage, it is the best way to precisely control bolt preload. Than is responsive, accurate, no torsional stress, no friction damage, can synchronize multiple bolt preload hydraulic torque wrenches, bolt tensioners advantages; therefore bolt tension preload in more stringent requirements for the occasion applied more widely. The disadvantage is the need to have sufficient elongation, and thus narrow axial space is very limited occasions.

Role of hydraulic bolt tensioners

Hydraulic bolt tension referred hydraulic tensioners, the role of its dynamic components of the original motivation of the mechanical energy is converted into fluid pressure energy, it refers to the hydraulic system of pumps, hydraulic bolt tensioners to provide power to the mechanical energy of a fluid hydraulic pumps transformation. Acting hydraulic bolt tension power components of the original motivation of the mechanical energy is converted into fluid pressure energy, it refers to the hydraulic system of pumps, which provides power to the entire hydraulic system.
