Description
Technical field
The utility model relates to compression device field, particularly relates to a kind of spring support for supporting, the mover assembly containing this spring support, the pump body structure containing this mover assembly, and the compressor containing this pump body structure.
Background technique
At present, reciprocating compressor all has the parts of similar bent axle, and these parts are used for the driving force running torque of motor being converted to reciprocating motion of the pistons.The conversion of this motion can cause the mechanical friction loss of reciprocating compressor very large.For solving the large problem of mechanical friction loss, in industry by target alignment linear compressor.Linear compressor eliminates the bent axle of rotary compressor, and piston moves reciprocatingly under linear electric motor drive in cylinder, completes the compression to refrigerant.Because the component of linear compressor reduce, complete machine structure becomes simple, not only increases compression efficiency, and noise when linear compressor runs simultaneously also diminishes, and is therefore widely used in the such as household electric appliance such as refrigerator, air-conditioning.
For linear compressor, piston, mover, spring support, resonant springs form mover assembly at resonant springs assembly center together by being bolted to, and resonant springs two ends are respectively by spring dead plate and spring cup fixed support.In cylinder, do linear reciprocating motion compression refrigerant at motor driving force effect lower piston, spring constantly stores and releases energy simultaneously, forms refrigeration cycle.Relative to traditional rotary compressor, the maximum feature of linear compressor is that precision-machined parts only has piston and cylinder, and processing cost is low, and structure is simple.But moved reciprocatingly by piston, thus require higher to the coaxality that each component assemble, following gap must be ensured: (1) gap between piston and cylinder.Piston in the cylinder to-and-fro motion time can produce pressurized gas, must ensure the sealability between piston and cylinder, prevent leakage of compressed gas, thus gap is very little, and general control is at 0.005mm ~ 0.010mm.(2) gap between mover and inner stator, to reduce leakage field loss, ensure that linear electric motor have higher efficiency, General Requirements controls between 0.2mm ~ 0.4mm.(3) gap between mover and external stator, main purpose is also that improve the efficiency of linear electric motor, General Requirements controls between 0.2mm ~ 0.4mm in order to reduce leakage field loss.
But it is more that mover assembly relates to part, above-mentioned 3 gaps generally ensure the assembly precision of mover assembly by assembly tooling.Existing spring support and spring cup are all generally that sheet metal part is stamped to form, and in order to make the structure of linear compressor more compact, generally all can there is bending to a certain degree.The spring support of this bending structure and spring cup Application comparison in current linear compressor is extensive.But, in experimentation, we find, even if the assembly precision of mover assembly is very high, when the spring support and spring cup that form mover assembly exist above-mentioned bending, very easily there is the phenomenon of eccentric wear between piston and cylinder, time serious, even occur the problem of seizing of piston.Analysis is learnt, when linear compressor runs, under electromagnet pull effect, because the point of action of spring support and spring cup is uneven, two kinds of parts are very easily deformed at bending part, thus spring is radially bent, cause the frictional force between piston and cylinder to increase, card cylinder phenomenon occurs.
