Technical field
The present invention relates to compressor, particularly relate to the housing of compressor.
Background technique
Compressor is the important composition parts that air conditioner, refrigerator etc. utilize the household electric appliance of cooling cycle system work.In general, compressor utilizes its parts that move under driven by motor (rolling piston or reciprocating piston etc.) to change mechanical energy into the pressure energy, realization is to the compression of compresser cylinder inner refrigerant, and refrigerant compressed is discharged compressor enters cooling cycle system and circulate.
Compressor commonly used mainly contains Reciprocting piston compressor, rotary compressor etc.Rolling piston compressor is modal rotary compressor, has characteristics such as volume is little, simple in structure, running is steady, noise is low, especially can adapt to variable parameter operation, so it is widely used on the air conditioner.
Fig. 1 shows the basic structure of the rolling piston compressor of using on a kind of air conditioner.As shown in Figure 1, compressor is a vertical structure, and cylindrical shell 4 is by loam cake 3 and lower cover 9 sealings.The compressor section of compressor and motor section are arranged in the cylindrical shell 4, and compressor section is located at the bottom of housing 4, and motor section is located at the top of housing 4.
Compressor section is made up of upper bearing (metal), lower bearing, cylinder cavity and piston 8.Form the cavity of cylinder between the upper bearing (metal) of compressor section and the lower bearing, piston 8 is set in the cylinder cavity, insert an end of bent axle 7 in the piston 8, piston 8 can rotate under the drive of bent axle 7.
The motor of motor section is made up of stator 5 and rotor 6, and stator 5 and rotor 6 are made of the iron core that the folded collection of silicon steel core sheet forms respectively, embed the winding of enameled cable coiled on stator 5 and the rotor 6.Rotor 6 is cylindric, directly is pressed into bent axle 7 in the rotor 6 and inserts in the cylinder cavity of stator iron core, has air gap to be separated by between rotor 6 and the stator 5.Stator 5 and rotor 6 windings outside source current by the time produce interactional magnetic field, the electromagnetic torque of generation rotates rotor 6 in stator 5.The rotor 6 that rotates drives pistons 8 by bent axle 7 and rotates, and enters refrigeration agent in the cylinder cavity with compression.
In the compressor operation, refrigeration agent enters in the cylinder cavity from the other suction silencing apparatus 10 of compressor housing, compressed refrigeration agent escapes and enter in the compressor housing from the distolateral exhaust port of cylinder cavity, and the steam outlet pipe 1 that is provided with from case top lid 3 conveying pipe of refrigerant of discharging compressor and entering cooling cycle system carries out refrigeration cycle again.
After compressor is compressed into the gas of High Temperature High Pressure with refrigeration agent, sends into refrigeration system again and circulate.Therefore, the housing of compressor is sealed by loam cake and lower cover, and has the performance of high temperature high voltage resistant.
The housing 4 of the compressor of above-mentioned prior art links together with loam cake 3 and lower cover 9 melting welding, and steam outlet pipe 1 all is that melting welding is connected with loam cake 3, binding tube 2 with loam cake 3, to avoid refrigeration agent and oil leak.
But the melting welding of above-mentioned compressor housing associated components connects makes that manufacturing process is numerous and diverse, cost of production is high, and associated components should not be changed after damaging.
Summary of the invention
At the existing problem of the compressor housing of above-mentioned prior art, the present invention has released the compressor housing structure that associated components is threaded, replace the compressor housing structure that melting welding connects, problem such as manufacturing process is numerous and diverse, cost of production is high to overcome, damage that parts should not be changed.
Screw thread fastening type compressor housing structure involved in the present invention, the housing of its compressor and loam cake and lower cover are respectively by being threaded.There is internal thread the upper edge of housing and the inboard of lower edge portion, the bottom outside of loam cake and the upper outside of lower cover have outside thread respectively, the outside thread of loam cake bottom outside is connected with the internal thread of housing upper edge inboard, and the outside thread of lower cover upper outside is connected with the internal thread of housing lower margin portion inboard.
Be arranged on the steam outlet pipe and the binding tube that cover and also be threaded with loam cake, steam outlet pipe is connected with the internal thread in loam cake corresponding setting hole respectively with the outside thread in the binding tube outside.
The unsintered tape that winding is arranged between the outside thread of the above-mentioned parts that are threaded and the internal thread is to ensure the sealing of threaded connection place.
Screw thread fastening type compressor housing structure involved in the present invention, the melting welding of housing associated components connect simplification manufacturing process, reduce production costs, and part replacement is convenient.
