2500 Bar Hydraulic Hand Pumps For Hydraulic Nuts

As a simple and convenient hydraulic power source, ultra-high pressure manual hydraulic pump is widely used in many fields such as shipbuilding industry, coal mining machinery, petrochemical, metallurgy, electric power and heavy machinery. And with its small size, light weight, easy to carry, strong safety and other advantages are accepted by the majority of users. In the 1990s, my country's electromechanical industry introduced imported advanced assembly and fastening technology, using high-strength hydraulic nuts and hydraulic tensioners as power sources and introducing ultra-high pressure manual hydraulic pumps. After running-in and testing with the domestic market, the ultra-high pressure manual hydraulic pump fully meets the market demand, with a working pressure of 100~300Mpa; a pressure reducing valve is installed in the pump, and a safety relief valve is also installed in the pump to prevent pressure overload; the secondary flow rate…
