The problem of weight weight.3, fuel tank, battery, oil pump assy and motor are built in shell, and the output end of motor is connected with oil pump,
Oil pump output end connects two quick couplings, while oil pump is communicated with fuel tank, and battery is connect with motor.Shell is functional by institute
Part covering, appearance looks elegant.4, the pump housing quantity of the power pump is changed to 6 pumps by traditional 4 pump housings (2 high pressures, 2 low pressure)
Body (3 low pressure, 3 high pressures), breaches the limitation of traditional pump housing quantity, and innovative 6 pump body designs of use greatly improve
The problem of oil liquid transmission efficiency of power pump, it is small to solve current power pump fuel delivery, low efficiency.5, the fast quick access of the power pump
Mouth selects concentric tube fast interface, it can be achieved that primary plug can be also turned on fuel-displaced, oil return circuit, and the interface can be realized
Plug with pressure, greatly improves working efficiency.
The characteristics of present device has low pressure oil supply amount big, and high voltage step-up speed is fast, steady and low noise of boosting.
The working principle of apparatus of the present invention is: providing power by battery, drives operation of oil pump by motor, oil pump passes through
Quick coupling is connected with fire-fighting and rescue tool, to drive fire-fighting and rescue tool work.When the system is operating, system pressure passes through
Low pressure (10MPa) → high pressure (72MPa) twin-stage is converted, it can be achieved that system pressure steps up, and boost process is steady, is reduced
Impact of the system to the pump housing and motor, improves the service life of electrodynamic pump and motor.The electrodynamic pump fast interface is selected
Concentric tube fast interface is, it can be achieved that primary plug can be also turned on fuel-displaced, oil return circuit, and the interface can realize with pressure insert
It pulls out, greatly improves working efficiency.
Present device provides power by battery, drives operation of oil pump by motor, by quick coupling can with it is any
The connection of fire-fighting and rescue tool, so that fire-fighting, traffic police team, industrial and mining enterprises and other rescue department's fire-fighting and rescue operations are more convenient,
With high security, the advantages of easy to use and low noise.Also, the electrodynamic pump is axial electrodynamic pump, has compact-sized, body
The advantages of product is small, light-weight, work efficiency is high and long service life.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is the structural schematic diagram of invention equipment.
