The difference between manual and electric hydraulic pump where

Date： 1970-01-01

Manual hydraulic pump and electric pump are relatively high frequency of use of the device, then what kind of difference between the two? These in turn will produce a different life and what impact it? These issues have always been the focus of attention.

As a simple manual pump hydraulic power source is widely used in many fields of shipbuilding industry, mining machinery, petrochemical, metallurgy, electric power and heavy machinery. And its small size, light weight, easy to carry, safety and other advantages by the majority of user acceptance. Electric pump is an important part of the hydraulic wrench, it can provide a pressurized hydraulic fluid for the hydraulic drive element, the electric pump hydraulic wrench may directly affect the quality of life.

Pump is to provide a stable power source, the main parameters are: pressure, flow rate; electric pump is a fluid supply device, is open supply, generally used for oil supply, water supply, enhance, the main parameters are: head, flow.

Pump: general points continuous and reciprocating pump oil through the completion of the action in the confined space, the basic structure is through the "hole / vacuum" range, by squeezing out the oil, with each cycle of the pump fixed oil, such as a gear pump, vane pump, piston pump; electric pump: general by the centrifugal force, the fluid extrusion, inertia, so that a continuous supply of the medium along the output path. Is a semi-closed draw media, the pressure is very unstable and can not provide the original as pressure (power source) can be used as conveying fluid power, linear and inversely proportional to the flow and head. An impeller pump, screw pump.

Through the above description, manual hydraulic pump industry, machinery, oil and other fields more common use of equipment, and electric pump with anti-corrosion, strong tolerance ability. With the increasing demand in many sectors of the pump device, these two types of products, they have a good advantage, how to further expand this advantage, enhance its role in industrial production, need more people help and attention.
