Description
Technical field
The invention belongs to Hydraulic Field, especially relate to a kind of constant pressure regulating system of large discharge separated type Accumulator arrangements.
Background technique
Along with the raising of hydraulic system applications occasion complexity, in short-term large discharge and long time constant pressure demand become a feature significantly, although adopt hydraulic power unit can provide large discharge in short-term, but energy consumption is very big, pressure surge is simultaneously also larger, although adopt Accumulator arrangements can provide large discharge in short-term, energy consumption is less, but pressure surge is larger, the angle therefore exported from constant pressure proposes a kind of constant pressure regulating system of large discharge separated type Accumulator arrangements.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of constant pressure regulating system of large discharge separated type Accumulator arrangements, ensures that long-time delivery pressure is constant, reduces system energy consumption.
For solving the problems of the technologies described above, the technical solution used in the present invention is: adopt large discharge separated type Accumulator arrangements, control system of invariable pressure and pipeline assembly to realize, large discharge separated type Accumulator arrangements is realized by multiple small flow Accumulator arrangements, and described small flow Accumulator arrangements comprises low starting friction power plunger type accumulator, high pressure resistant nitrogen bottle and air valve, many groups small flow Accumulator arrangements is combined and can be formed large discharge Accumulator arrangements, described control system of invariable pressure comprises large discharge cartridge valve, controller, pressure transducer and cable, cable connects large discharge cartridge valve, controller and pressure transducer, controller is by the comparison of setting pressure and pressure transducer measuring pressure, the opening of real-time adjustment flow cartridge valve, thus ensure that delivery pressure is constant, described pipeline assembly comprises pneumatic circuit and hydraulic pipe line, described large discharge Accumulator arrangements is connected with large discharge cartridge valve by hydraulic pipe line, output flow can be changed by the opening controlling large discharge cartridge valve and change delivery outlet pressure simultaneously, this delivery outlet is configured with pressure transducer, the pressure of delivery outlet can be detected in real time by pressure transducer, pneumatic circuit and hydraulic pipe line complete large discharge Accumulator arrangements and large discharge cartridge valve, connection between pressure transducer, and a kind of constant pressure regulating system of large discharge separated type Accumulator arrangements is formed together with control system of invariable pressure.
Further, small flow Accumulator arrangements adopts separated type nitrogen bottle and plunger type accumulator to realize.
Further, nitrogen bottle adopts has high voltage bearing nitrogen bottle, is configured with gas-valve special and safety valve, ensures the conformity of nitrogen pressure, consider safety simultaneously, be configured with safety valve, avoid system overpressure.
Further, in order to ensure that system has constant flow and exports, the plunger type accumulator with low starting friction power is adopted to realize.
Further, the aperture that large discharge cartridge valve changes valve port according to the instruction of controller changes output flow, thus changes delivery pressure.
Further, delivery pressure feeds back to controller, and controller obtains the control signal of large discharge cartridge valve according to setting pressure and delivery pressure, ensures that delivery pressure is constant.
The advantage that the present invention has and good effect are: adopt large discharge separated type Accumulator arrangements control system of invariable pressure of the present invention, can not only effectively reduce system energy consumption, and can ensure that large discharge exports in short-term, realize constant pressure and control.
