Abstract

The utility model relates to a line-frequency wave-dividing type energy-saving compressor. Two electromagnets are axially connected in a vacuum inner casing, and the joint is a shared gyromagnetic ring. The two electromagnets also share one armature iron and two diodes, wherein, the positive electrode of one diode is connected with the negative electrode of the other diode to form one power line, and the other electrodes of the two diodes are respectively connected with one end of the working coils of the two electromagnets. The other ends of the working coils are connected as the other power line. The electromagnets generate switching electromagnetic force during work when power is on, and the electromagnetic force drives the armature iron together with a piston to carry out reciprocal motion to carry out air suction and compression.

Description

Line-frequency wave-dividing type energy-saving compressor

The utility model is by two diodes the positive and negative of industrial frequency AC to be separated, and works in the electromagnet of two moving iron of a shared rank, makes the moving iron of rank advance air-breathing and compressor exhaust together with piston by the ac frequency to-and-fro motion.

At present, the various types of compact machine all is used as power with motor, curved shaft type is arranged, the slip pipe formula, sliding vane, rolling rotor-type, because the bearing loss of motor own, the loss of rotational acceleration, by single-phase 50Hz two-pole machine, rotating speed should be 3000 rev/mins, and existing as the Japanese E44 of Toshiba, 101 compressor maximum speeds can only 2900 rev/mins, and it 100 changes and lose, and adds loss in the transmission process, as the bent axle transmission, the axle envelope, the frictional loss of bearing, frictional loss between the slide block of slip pipe formula and the slip pipe, they all are that the frictional loss of working under high speed is quite big, rotary compressor too, thereby cause long loss of life-span big to compressor.

The utility model purpose provides a kind of energy-saving compressor, it can not only be by ac frequency per minute 3000 work of changing a job, and can save the frictional loss in motor, bearing and the driving mechanism process, directly drives the moving ironwork plug of rank by electromagnetic force, it is long, energy-conservation to reach the little life-span of friction.

The purpose of this utility model is to realize like this, in vacuo in the shell two electromagnet shafts to connection, the joint is shared time magnet ring, and the moving iron of a shared rank, piston is by being connected on the moving iron two ends of rank, two quiet iron cylinder bodies are at two electromagnet two ends, circle is cylinder body in the quiet iron, two-piston is worked respectively within it, two line windows are outside the moving iron of rank and leave certain space, be as the criterion not rub, two actuating coils are in wire frame, the outer garden of coil is respectively that round permanent magnetism returns magnetosheath, twice the same polarity of magnetosheath is connected with shared time magnet ring, another utmost point is connected with two quiet iron respectively, the body fixed cover, outside returning magnetosheath, two ends are separately fixed at two quiet iron outside circles, fixed cover is connected by hanging spring with the vacuum inner casing, cylinder head, air-valve assembly, be separately fixed at two quiet iron two ends with screw, between cylinder head and the vacuum inner casing shock-absorbing spring is arranged respectively, vacuum casting is in vacuo outside the shell, middle interior two ends of vacuum casting and inner casing be two ends shock-absorbing spring vibration damping outward by rubber ring is arranged, and inner casing and shell have wiring terminal respectively, terminal box is installed in shell wiring terminal place, two diodes, wherein a positive pole is connected with the another negative pole, and with power line wherein one be connected, two another utmost points of diode respectively with two coils wherein an end be connected, two coil the other ends connect with another root power line and join, and constitute the partial wave loop, and the moving iron of rank is made the garden cylindricality with electrolytic iron or with the sial pure iron, the moving outer garden of rank has axial Peng Kou to heart, and coiling window and shared time magnet ring are one with anti-fluoroplastic notes, and shared time magnet ring is made with soft magnetic material, vacuumize in the middle of inner casing and the shell, with every dry sound, copper pipe is used for air intake-exhaust and picks out pipe; During energising work, when positive wave by forward diode wherein and corresponding be connected wherein a coil is formed loop works the time, producing electromagnetic force makes the moving iron of rank moving to the correspondence quiet Railway transportation of working, so and the another diode is not because of oppositely can not working by conducting another coil, then reverse two utmost point conductings during negative wave, and corresponding coil working, forward diode can not conducting, positive negative wave variation along with Ac, the moving iron of rank is answered coil exchange work, and press the ac frequency to-and-fro motion, drive piston and reach air-breathing compression purpose.

Because adopt such scheme, this compressor saves motor, and does not have bearing and driving mechanism frictional loss, simple in structure, easily manufactured, cost is low, and the little life-span of abrasion is long, thereby energy consumption significantly reduces.

Below in conjunction with drawings and Examples the utility model is further specified.
