Pressure/torque =3. 14* thread diameter/pitch
Pressure =3. 14* torque/pitch
Known pitch P=0.35mm thread diameter d =1.6 mm.
When the torque = 1.2 kg*cm*f, the pressure = 3.14 *1.2 * 9.8/0.035 =1055n (about 108kg).
We have adopted more than ten patented technologies in the manufacture of hydraulic wrenches, which are different from the mechanical manufacturing processes of other peers. All hydraulic machines and tools, including accessories, have achieved standardized design and production. Hydraulic wrenches and pumps have to go through 72 hours of trial operation before leaving the factory, and they can only leave the factory after passing the test.
2. The fuselage is made of high-tech aerospace materials (aluminum-titanium alloy) and ultra-high strength alloy steel, which are integrally formed. The fuselage has the advantages of light weight, high strength and good toughness, which is 10% lighter than the products of peers, and is easy to operate.
3. The design of hydraulic wrench conforms to modern ergonomics, and the use is more humanized. At the same time, it can meet the maximum torque requirements of all industries and most working conditions.
4. Stable performance: ratchet, housing, oil cylinder, transmission shaft and other key components are equipped with advanced CNC machining center equipment, which improves the interchangeability of parts.
5. Good safety: Pull the Ji lock, press it gently, and fine-tune the reaction arm 360 degrees to be fixed on a solid fulcrum at will.
6. High precision: high precision ratchet is adopted to ensure the accuracy as high as 1%, which is much higher than that of peers.
7. Light weight and small volume: aluminum-titanium alloy is adopted, which greatly reduces the weight of the hydraulic wrench. Easy-to-operate industries, especially the wind power industry, are particularly important.
8. Complete varieties: both torque hydraulic wrenches and hollow hydraulic wrenches can be produced, and the torque range is 200 NM to 200,000 nm.
9. Adequate inventory: the only company in the same industry that has achieved planned inventory.
10, hydraulic wrench transmission shaft, its raw materials and casting quality are in sync with the top first-line brands at home and abroad.
