Abstract
Ultra-High Pressure Hand Pump, it is made of fuel tank, some check valves, some overflow valves, low-lift pump, high-pressure pump and fast interface, fuel-tank outlet check valve A is connected with overflow valve A, overflow valve A outlets are connected with low-lift pump and check valve B respectively, check valve B is connected with overflow valve B, overflow valve B outlets are connected with high-pressure pump and check valve C respectively, and check valve C is connected with fast interface.The present invention solve thes problems, such as that existing hand-hydraulic pumpage is small, it is 1.5 2 times of common manual pump, and upper pressure speed is fast, and this hydraulic hand-pump use aluminum alloy material, has the characteristics that upper to press that speed is fast, flow is big, reliability is high, be convenient for carrying, appearance is more beautiful.
Description
Technical field
The present invention relates to a kind of fire-fighting and rescue instrument, and in particular to a kind of Ultra-High Pressure Hand Pump.
Background technology
Hydraulic pump is the common component of rescue tool, hand-hydraulic pumpage is small currently on the market, heavier-weight and on
Pressure is slow, it has not been convenient to carries, have impact on rescue efficiency, fire-fighting and rescue can not be met to rescuing speed increasingly higher demands.
The content of the invention
The present invention provides a kind of Ultra-High Pressure Hand Pump, to solve, discharge capacity existing in the prior art is small, heavier-weight
The problem of slow is pressed with upper.
The technical solution adopted by the present invention to solve the technical problems is：
A kind of Ultra-High Pressure Hand Pump, by fuel tank, some check valves, some overflow valves, low-lift pump, high-pressure pump and fast interface group
Into fuel-tank outlet check valve A is connected with overflow valve A, and overflow valve A outlets are connected with low-lift pump and check valve B respectively, check valve B
It is connected with overflow valve B, overflow valve B outlets are connected with high-pressure pump and check valve C respectively, and check valve C is connected with fast interface.
Above-mentioned fuel-tank outlet sets strainer.
For present device in use, when low-lift pump and high-pressure pump are in oil suction state, low pressure chamber hydraulic oil passes through strainer
Enter low-lift pump with check valve A, high pressure chest hydraulic oil enters high-pressure pump by strainer, check valve A, overflow valve A and check valve B.
When low-lift pump and high-pressure pump are in oil extraction state, low pressure chamber hydraulic oil is entered fast by check valve B, overflow valve B and check valve C
Interface, high pressure chest hydraulic oil enter fast interface by check valve C.When the pressure of low-lift pump reaches setting oil pressure relief, hydraulic pressure
Oil is back to fuel tank by overflow valve A.When the pressure of high-pressure pump reaches setting oil pressure relief, hydraulic oil is returned by overflow valve B
It flow to fuel tank.
The present invention solve thes problems, such as that existing hand-hydraulic pumpage is small, is 1.5-2 times of common manual pump, and
Upper pressure speed is fast, and this hydraulic hand-pump uses aluminum alloy material, with upper pressure speed is fast, flow is big, reliability is high, conveniently
Carry, the characteristics of appearance is more beautiful.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the structure diagram of present device.
1 fuel tank, 2 strainers, 3 check valve A, 4 low-lift pumps, 5 overflow valve A, 6 check valve B, 7 high-pressure pumps, 8 overflow valve B, 9 in figure
Check valve C, 10 fast interfaces.
Embodiment
As shown in the figure, a kind of Ultra-High Pressure Hand Pump, by fuel tank 1, some check valves, some overflow valves, low-lift pump 5,
High-pressure pump 8 and fast interface 10 form, and the outlet of fuel tank 1 sets strainer 2, and 1 Outlet check valves A3 of fuel tank is connected with overflow valve A5, overflow
Valve A5 outlet is connected respectively with low-lift pump 4 and check valve B6, check valve B6 is connected with overflow valve B8, overflow valve B8 export respectively with
High-pressure pump 7 is connected with check valve C9, and check valve C9 is connected with fast interface 10.
For present device in use, when low-lift pump and high-pressure pump are in oil suction state, low pressure chamber hydraulic oil passes through strainer
Enter low-lift pump with check valve A, high pressure chest hydraulic oil enters high-pressure pump by strainer, check valve A, overflow valve A and check valve B.
When low-lift pump and high-pressure pump are in oil extraction state, low pressure chamber hydraulic oil is entered fast by check valve B, overflow valve B and check valve C
Interface, high pressure chest hydraulic oil enter fast interface by check valve C.When the pressure of low-lift pump reaches setting oil pressure relief, hydraulic pressure
Oil is back to fuel tank by overflow valve A.When the pressure of high-pressure pump reaches setting oil pressure relief, hydraulic oil is returned by overflow valve B
It flow to fuel tank.
The present invention solve thes problems, such as that existing hand-hydraulic pumpage is small, is 1.5-2 times of common manual pump, and
Upper pressure speed is fast, and this hydraulic hand-pump uses aluminum alloy material, with upper pressure speed is fast, flow is big, reliability is high, conveniently
Carry, the characteristics of appearance is more beautiful.
