Description
Technical field
The utility model relates to a kind of device of convection cell supercharging.
Background technique
At present, common supercharging device is made up of pressurized machine, selector valve, one-way valve, accumulator, compressor, its basic principle is: compressor is with air compression, compressed air (more than the 5Mpa) promotes the intensifier piston motion, utilize the difference of pressurized machine big piston and small piston area to realize supercharging, pressure ratio is the ratio of big piston area and small piston area, P
Fluid=(A
Greatly/ A
Little) P
AirThe ratio of common big or small piston area is 10: 1～25: 1, and therefore, pressurized machine output high pressure fluid can reach more than the 100MPa.During the piston arrives stroke terminal, selector valve makes air path change direction automatically, and then promotes the big piston negative line feed, and this moment, high-pressure liquid was held output at other.If this high-pressure liquid is directly delivered to outlet end, delivery pressure will be pulsed so, and this produces periodic swinging to pipe-line system.For obtaining stable high-pressure liquid, be everlasting an accumulator is set between pressurized machine and the outlet end, eliminate pressure pulsation, reach the purpose of constant voltage.
But air compressor is bulky, and noise is big, therefore uses inconvenience.And, because air compression is strong, and need higher breakout pressure (2MPa) could promote piston, as working fluid, efficient is not high.The air thermal conductivity is poor, and pressurized machine can not work long hours.In addition, the pressurized machine stroke can't be regulated, and pumping rate is uncontrollable.Moreover accumulator only plays eliminates the pressure pulsation effect, can not control required goal pressure accurately and efficiently.
Summary of the invention
The purpose of this utility model is to provide a kind of fluid pressurized device, and this device volume is less, and working fluid efficient height, breakout pressure are low, and pressurized machine can work long hours, and its stroke can be regulated, and can accurately control required goal pressure.
The technological scheme that its technical problem that solves the utility model adopts is, replace air as working fluid with transformer oil, motor replaces air compressor to provide motive force for oil pump, pass through selector valve, oil pump is connected with pressurized machine, treat that charging fluid is communicated with pressurized machine by one-way valve, pressurized machine is connected with accumulator again.
A kind of fluid pressurized device, mainly form by motor, oil pump, fuel tank, selector valve, pressurized machine, one-way valve, accumulator etc., it is characterized in that, described fuel tank is connected with oil pump, working fluid in the fuel tank is a transformer oil, and oil pump is connected with pressurized machine by selector valve, treats that the charging fluid case is communicated with pressurized machine by one-way valve, pressurized machine is connected with accumulator by another one-way valve again, and described pressurized machine is made up of low-pressure cavity, hyperbaric chamber, big piston, small piston, oil inlet and outlet etc.
In the pressurized machine of the present utility model, stroke adjuster also is installed,, is regulated pumping rate to change stroke of piston in low-pressure cavity.
In the accumulator of the present utility model, go back setting pressure controller and voice guard, set a goal pressure during operation, when pressure surpasses goal pressure, discharge automatically, and report to the police by voice guard.
Working procedure of the present utility model is achieved in that oil pump is under motor drives, transformer oil in the fuel tank is squeezed into the pressurized machine low-pressure cavity by selector valve, promote big piston and move right, make that the fluid in the hyperbaric chamber is compressed, obtain high pressure, enter accumulator by one-way valve.During the piston arrives stroke terminal, selector valve makes oil circuit change direction automatically, and then promotes the big piston negative line feed, and this moment, high-pressure liquid was exported from the other end one-way valve, entered accumulator.If the goal pressure that the pressure Overpressure of a safety valve controller of accumulator is default, then high-pressure liquid flows out from pressure regulator valve, and produces sound alarm.
The beneficial effects of the utility model are, device volume is less, working fluid efficient height, and breakout pressure is low, and pressurized machine can work long hours, and its stroke can be regulated, and can accurately control required goal pressure.
