driven mechanical pump set pressure, the correct way is to make the driving pressure higher than the back pressure 1-1.5kg/cm2 (15-20psig). In most cases this is correct. But sometimes in order to achieve the requirements of the pump displacement, the need will drive pressure was set slightly higher. Driving pressure is high, the downside is [...]

different from carbon steel elbow stainless steel elbow punch mainly to the different materials, which contains the chemical composition of the surface for a long time will remain elbow will not rust, corrode easily. stainless steel to stainless steel, corrosion resistance as the main feature, and the chromium content of at least 10.5%, the maximum [...]

conducting oil pump is generally shielded pump, shielded from the cooling water jacket cooling pump bearings, you can check the cooling water system: flow, pressure is normal, cooling water filter is blocked, then check the vibration directions of the Green Line range is better. cutting impeller is reduced head and flow based on pump performance [...]

bearing Valve causes early damage and precautions Valve engine as an important part of its life this should be consistent with the overall engine life, but often found in the use of life is far below the Valve engine as a whole life, especially the valves, valve seats, valve guides shorter life expectancy and other [...]

hydraulic drive technology for the use of hydraulic pressure processing equipment, can be used to complete a variety of forging and pressure forming. For example, steel forging, metal structure of the molding, plastic products and rubber products repression. Hydraulic machine is the first application of hydraulic machinery, hydraulic transmission has now become the main driving [...]
