Vane pump performance parameters, including flow, head, power, efficiency, vacuum suction height required or necessary NPSH, speed and so on.
(1) head. Refers to the unit weight of water from the pump inlet to the pump outlet to increase the energy, denoted by H, the unit is mH2O, abbreviated as m. Pump head on the pump nameplate design is the head of the pump, which corresponds to through the design Head when the flow, also known as rated head. Pump head work is always greater than the actual lift (net head).
(2) efficiency. The efficiency on the pump nameplate corresponds to the efficiency at design flow rate, which is the highest efficiency of the pump. Energy loss within the pump can be divided into three parts, namely hydraulic loss, volume loss and mechanical loss.
(3) Suction vacuum height or necessary NPSH allowance. Is characterized vane cavitation performance parameters, used to determine the pump installation elevation, in units of m.
Stone crusher is suitable to crush the medium hardness and brittle material in the mining, cement, coal, metallurgy, building materials, highway, gasification and so on. It has the simple structure, high crushing Ratio, high production efficiency, and can be dry or wet crushing . The grate gap of the Stone Crusher can be adjusted according to user requirements to get the different final sizes to meet the different needs of different users. Stone Crusher is a necessary equipemnt for mining and quarry.
