Abstract
The invention belongs to the energy-saving field of pneumatic system and realizes a bidirectional supercharging-type electric gas supercharging device. The supercharging device mainly relates to a gas supercharging technology which adopts combined driving of a motor and a low-pressure gas source. The pneumatic system with combined driving of the motor and the low-pressure gas source adopts a double-acting cylinder. When in use, the low-pressure source gas is fill in one side of a piston in the cylinder so as to push the piston and the motor to together drive the piston to compress the low-pressure air at the other side, thus realizing supercharging, sufficiently utilizing the energy of the low-pressure gas, and reducing the energy consumption of the motor. A frequency-conversion controller takes the pressure of the high-pressure gas as a target and adjusts the starting, running and stopping of the motor in real time, thus outputting stable pressure and reducing the frequent starting and stopping of the motor. Furthermore, the gas supercharging machine adopts the double-acting cylinder, thus having simple structure, small vibration and low noise.
Description
The invention belongs to energy-saving field of pneumatic, relate to a kind of bidirectional supercharging-type electric gas supercharging device.
Background technique
Gas pressurized device is the key technology of energy-saving field of pneumatic.In pneumatic system, some occasion often needs a small amount of, partial high pressure gas.For example: indivedual or partial devices need be used high pressure in the gas circuit; Because remote gas transmission or gas leakage cause main gas circuit pressure to descend, and can not guarantee the minimum working pressure of Pneumatic actuator; The space is narrow, can not dispose the heavy caliber cylinder, but ouput force must guarantee again, or the like.Solve this type of problem, what adopt usually at present is local supercharge method, and it is to utilize supercharging device to obtain pressurized gas, can save cost, reduce bleed pressure, especially pneumatic system is carried out reducing energy consumption, and its effect is more outstanding.
The pneumatic system boosting method roughly has following two kinds at present:
One, utilize the extra power system that pressurized gas institute energy requirement is provided, as all gases pressure-increasing machine, this type of pressure-increasing machine mostly is that repacking forms to compressor, and its characteristics are that power is big, delivery pressure and flow are big, but its volume is big, can not effectively utilize the low-pressure gas source gas energy, and capacity usage ratio is low, common in addition gas-booster lacks controller, frequent start-stop to the impact of the electrical network of factory, gas circuit and very big to the damage of equipment itself, is unfavorable for the popularization in industry spot.
Two, by reducing pressurized machine supercharging side piston area, reach the purpose of supercharging.This class pressurized machine all is power, simple in structure, characteristics such as volume is little with the pressurized gas, is promoted widely under some need the occasion of a small amount of, partial high pressure gas.But pressurized machine driving side low-pressure gas directly discharges atmosphere, and energy loss is big, and the efficient of system is low.This type of pressurized machine discharge capacity is little in addition, when the industry spot gas demand is big, need to increase many pressurized machines, this will increase the input of equipment, so has limited its application in industry spot.
The present invention adopts motor, low-pressure gas source to unite driving, VFC, double-acting cylinder gas boosting mode, and capacity usage ratio height, output flow are greatly, vibration is little, noise is low, the delivery pressure adjustable extent is big, has the excellent popularization prospect.
Summary of the invention
The objective of the invention is: a kind of simple in structure, volume is little, vibration is little, noise is low, energy-saving effect is remarkable, automaticity is high bidirectional supercharging-type electric gas supercharging device is provided.
Technological scheme of the present invention is:
1. motor, low-pressure gas source are united driven plunger.During work, low-pressure gas source gas charges into the chamber of piston one side in the cylinder, with the common driven plunger of motor the mortgage air in its opposite side chamber is compressed, and realizes supercharging.
2. frequency-variable controller is a target with the pressure of pressurized gas, control in real time motor startup, move, stop, with the output pressure stable, and reduce the frequent start-stop of motor.
Embodiment:
1. gas charges into the chamber B and motor (10) the associating live axle (11) of cylinder (3) through one-way valve (1) from low-pressure gas source, piston is to the gas boosting in the chamber A, chamber A mesohigh gas charges into air-capacitor (6) through one-way valve (4), and last pressurized gas output to gas equipment.When under the effect of axle (11), commutating when terminal on cylinder (3) the piston arrives stroke, gas charges into chamber A and motor (10) from low-pressure gas source through one-way valve (2) and unites and drive bent axle (11), piston is to the supercharging of cylinder (3) chamber B gas inside, chamber B mesohigh gas charges into air-capacitor (6) through one-way valve (5), and last pressurized gas output to gas equipment.This is a work cycle of pressurized machine.
2. frequency-variable controller (9) is according to the operation of the size control motor (10) of the interior gas pressure of air-capacitor (6), when being lower than pressure, air-capacitor (6) pressure sets down in limited time, frequency-variable controller (8) control motor (10) quickens operation (if motor is out of service, starting electrical machinery then), increase pressure-increasing machine pressurized gas discharge capacity; When the pressure of gas in the air-capacitor (6) was higher than the pressure capping, frequency-variable controller (9) control motor (10) ran slowly, and reduces pressure-increasing machine pressurized gas discharge capacity; When air-capacitor (6) internal air pressure is stabilized in the pressure setting range for a long time, frequency-variable controller (8) then cuts off motor power, and motor (10) is out of service.Realize that gas pressure remains in the pressure setting range in the air-capacitor.
Advantage of the present invention is: the present invention is simple in structure, vibration is little, noise is low, energy-saving effect is remarkable, automaticity is high, helps the popularization at industrial energy saving scene.
