The difference between manual hydraulic pump and electric hydraulic pump

[Asian Fluid Network News] Manual hydraulic pumps and electric hydraulic pumps are relatively high frequency of use of equipment, so what is the difference between the two? What impact will these differences have on production and life? These issues have always been the focus of attention. The difference between manual hydraulic pump and electric hydraulic pump Manual hydraulic pump as a simple and convenient hydraulic power source is widely used in shipbuilding industry, coal mining machinery, petrochemical, metallurgy, electric power and heavy machinery and other fields. And its small size, light weight, easy to carry, security and other advantages are accepted by the majority of users. Electric hydraulic pump hydraulic wrench is an important component, it can provide hydraulic fluid pressure of a hydraulic component, the quality of the electric hydraulic pump may directly affect the life of the hydraulic wrench. Hydraulic pump is to provide a stable power source, the main parameters are: pressure, flow; electric pump is a fluid supply equipment, is an open supply, generally used for oil supply, water supply, upgrading, the main parameters are: head, flow. Hydraulic pump: generally divided into continuous and reciprocating, are done in a confined space by the pump oil movement, the basic structure is through the "hole / negative pressure" oil, through the extrusion of oil, each cycle of the pump Fixed amount of oil, such as gear pumps, vane pumps, piston pumps, etc .; Electric pump: generally through the centrifugal force, fluid extrusion, inertia, so that the media along the output path of continuous supply. Is a semi-enclosed drawing medium, the pressure is very unstable, can not be used as a pressure to provide the original (power source), can be used as the fluid transmission power, and the flow and lift linearly inversely proportional. Such as the impeller pump, screw pump. Through the above introduction, manual hydraulic pump industry, machinery, petroleum and other fields more common use of equipment, and electric hydraulic pump with anti-corrosion, anti-fouling ability and so on. With the increasing demand for pump equipment in many industries, both of these industries have very good advantages for both types of products. How to further expand this advantage and enhance their role in industrial production requires more people Help and attention.
