The use of hydraulic wrenches
Hydraulic wrenches are widely used; in marine engineering, petrochemical, wind power, hydropower, thermoelectricity, mining, machinery, steel mills, rubber, pipelines and other industries in the construction, overhaul, repair and other work, hydraulic torque wrenches for large-size bolts are an important tool for the installation and disassembly of the tools; there are other tools irreplaceable, not only easy to use, but also to provide the torque, the torque repetition precision The torque repeating accuracy is about +3%.

How to use wave pressure wrench
Pre-operation check: 1 ) Flammable and explosive environments
1 ) flammable and explosive environment shall not use electric hydraulic pump, should use pneumatic hydraulic pump.
2 ) Check the electric pump operating voltage to meet the 220V.
3) Check the hydraulic wrench pump pressure adjustment, filtration, oil injection triplex device, drainage, add 46 # anti-wear hydraulic oil, intake pressure adjustment.
4 )Check the hydraulic oil pump oil level in the 0 line above the standard, hydraulic oil clear and transparent. Specialized hydraulic oil should be added, prohibited mixing of other oils.
5 ) Check the high pressure hose without bending and other damage, connect the first straighten the hose shall not be tangled, plug socket wipe clean without dirt, will be quick release couplings into the end to ensure that the connection is reliable, and hand will be connected to the hydraulic pump.
Make sure the connection is reliable and lock the threaded sleeve tightly by hand, otherwise the check valve in the quick release coupling will not be able to supply oil normally if it is not opened.
