Technical field

The present invention relates to compressor protection technical field, specially a kind of equipment using pressure difference protection compressor.

Background technique

Compressor is a kind of driven fluid machinery that low-pressure gas is promoted to high pressure gas, is the heart of refrigeration system It is dirty.It is operated after compressing with piston to it, to row from the refrigerant gas of air intake duct sucking low-temp low-pressure by motor The refrigerant gas of high temperature and pressure is discharged in tracheae, provides power for refrigeration cycle.

Due to the particularity using function of compressor of air conditioner, then compressor of air conditioner, freezer compressor and the compressor that dries Upper set up is equipped with external protector, and such external protector is to adjust the bimetallic for suppressing temperature by adjusting screw Piece height, so as to adjust protector action temperature and other performances；This kind of protector technology makes by selecting bi-metallic sheet Material, i.e. its resistance value are different, to adjust the electrical parameter in the protector course of work, reach matching and require.

If commonly known is that compressor continues working and can generate a large amount of thermal energy, and sheet metal has melting point, works as thermal energy Sheet metal will be burnt out by reaching a certain level, it is made to lose original function, can also cause fire, therefore one under serious situation Kind is come into being using the equipment of pressure difference protection compressor.

Summary of the invention

To realize the above-mentioned purpose for protecting compressor using pressure difference, the invention provides the following technical scheme: a kind of utilization The equipment that pressure difference protects compressor, including shell, the internal activity of the shell are connected with telescopic rod, and the two sides of telescopic rod are solid Surely it is connected with pressure plare, the surface of pressure plare offers head tank, and the surface of head tank is fixedly connected with adjusting packet, and head tank is remote Side from pressure plare is connected with air bag, and the top of shell is fixedly connected with guard box, the internal activity of the guard box It is connected with bellows, the upper end of bellows is fixedly connected with damping block, and damping block is fixedly connected with soft far from the side of bellows Property pipe.

The beneficial effects of the present invention are: by the suitable position that shell and guard box are placed on to compressor, and according to pressure The power adjustment of contracting machine adjusts the contact area of packet with head tank, and then controls the size that pressure is gone in air bag release, regulates it Afterwards, air bag slowly releases gas through adjusting packet, and enters in airflow channel, and portion gas is flowed into through the upper end of telescopic rod Bellows interior, bellows is blown by gas will push damping block and moves up with flexible pipe, when being moved at the top of guard box, Compressor stops working；At the same time telescopic rod by air-flow blow and airflow channel in pressure influenced, can also move up, When damping block is moved at the top of guard box, gas stops flowing, and folding rod loses support force and drawn by hydraulic stem toward opposite direction It is dynamic, bellows is moved down, damping block falls, and compressor is reworked, in cycles, compressor intermittent work, thus Achieve the effect that protect compressor using pressure difference.

Preferably, the pressure plare is provided with airflow channel far from the side of air bag, and air-flow can be in the of short duration shape of airflow channel At pressure difference.

Preferably, the telescopic rod includes folding rod, and the surface activity of folding rod is connected with hydraulic stem, and hydraulic stem plays multiple The effect of position.

Preferably, the lower end of the bellows is flexibly connected with telescopic rod, and gas is facilitated to flow directly into the inside of bellows.

Preferably, the inside of the air bag offers flow duct, flows directly into adjusting packet convenient for the gas in air bag.

Preferably, the right end of the flow duct is flexibly connected with packet is adjusted, and adjusts packet as bulk, and have certain contraction Ability.

Preferably, the left end of the flow duct is fixedly connected with the casing.

Preferably, the telescopic rod is located at the center of airflow channel, convenient for directly controlling the size of pressure difference.
