Abstract
The utility model discloses a piston-typed compressor, which comprises a casing that is formed by an upper cover and a lower shell; an air cylinder body, a piston component and a driving motor are arranged inside the casing; the driving motor and the air cylinder body are fixed on a crank box; a spring bracket is arranged inside the casing; the bracket is provided with a marshall spring; the crank box is fixed on the marshall spring. By adjusting the internal structure of the compressor, the internal buffer spring of the compressor is free from fracture under the serious shaking situation; moreover, during the running process of the compressor, a balancing status can be realized, thereby reducing the vibration of the casing of the compressor and the noise caused by the vibration of the casing of the compressor.
Description
Technical field
The utility model relates to the structure of Reciprocting piston compressor, and the particularly vibration that produces when cylinder interior is carried out straight reciprocating motion about piston is unlikely to be diffused into whole compressor and the damping spring installed.
Background technique
In general, small-sized piston formula compressor is to accept power from motor, refrigeration agent is compressed, thus the mechanical device of raising refrigerant pressure.It is applied to household electric appliance such as refrigerator, air-conditioning at large, and also is widely used industrial.
For general reciprocating-piston compressor, piston moves back and forth in cylinder interior, and then compression refrigerant acting, be connected by spring between working body that parts such as piston, cylinder and motor are formed and the external casing, spring is used for the vibration for housing of buffer motor and piston motion process.In existing piston formula compressor arrangement, working body is connected with compressor housing under the effect of pulling force by the pendulum spring of metal usually.But the situation of fracture easily because jolt unexpectedly in the transportation and vibrate and pendulum spring is overloaded, takes place in this Placement in the actual shipment process.In order to address this problem, the utility model is adjusted the internal structure and the annexation of compressor, makes it under the characteristics that keep miniaturization, can also reach new state of equilibrium when making the whole compressor running after annexation is adjusted.
Summary of the invention
The purpose of this utility model is: provide a kind of piston compressor that can keep compressor internal damping spring can not rupture at the deficiencies in the prior art under high vibration.
The technical solution of the utility model is:
A kind of piston compressor, include the housing that loam cake and lower casing are formed, cylinder block, piston assembly, drive motor are installed in housing, it is characterized in that: drive motor and cylinder block all are fixed on the crankcase, spring bracket is installed in the housing, marshall springs is installed on the support, and crankcase is fixed on the marshall springs.
An optimal technical scheme of the present utility model: marshall springs is mounted obliquely between spring bracket and the crankcase, is advisable with 5～30 ° in the angle of inclination.
The beneficial effects of the utility model are: by compressor inner structure is adjusted, compressor internal damping spring under high vibration can not ruptured, and in the compressor operating process, can reach state of equilibrium, reduce the vibration of compressor housing and the noise that therefore causes.
Description of drawings
Fig. 1 is a piston compressor schematic representation of the present utility model.
Wherein, reference character: 1 is motor, and 2 is motor shaft, and 3 is spring bracket, and 4 is marshall springs, and 5 is lower casing, and 6 is bent axle, and 7 is loam cake, and 8 is piston, and 9 is cylinder block, and 10 is crankcase.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Specific embodiment of the utility model, as shown in Figure 1, a kind of piston compressor includes the housing that loam cake 7 and lower casing 5 are formed, and loam cake 7 and lower casing 5 usefulness 2.5-3.5mm thickness steel plate stretch formings pass through CO
2The protection solid welding is tightly connected surely and forms an airtight metallic cavity, and oil-filled POE polyesters lubricant oil in cavity is used for lubricated each zero, parts matching surface.Working body is installed in housing, and working body comprises crankcase 10, is fixed on cylinder block 9, motor 1 on the crankcase 10, and motor 1 is selected single-phase asynchronous AC motor for use, and motor synchronous rotating speed 50Hz is 3000rpm, and 60Hz is 3500rpm.Motor shaft 2 passes crankcase and is connected with bent axle 6, and bent axle 6 is by transmitting assemblies driven plunger 8 to-and-fro motion in cylinder block 9, and the compression refrigeration medium does work.Be evenly equipped with 3 spring brackets 3 in the housing, marshall springs 4 is installed on the spring bracket 3, whole working body is fixed on the marshall springs 4 by crankcase, and marshall springs can be adjusted according to the different of working body in the compressor with the angle of vertical direction, and the adjustment range of angle is between 0～30 °.
Claims (3)
1. piston compressor, include the housing that loam cake and lower casing are formed, cylinder block, piston assembly, drive motor are installed in housing, it is characterized in that: drive motor and cylinder block all are fixed on the crankcase, spring bracket is installed in the housing, marshall springs is installed on the support, and crankcase is fixed on the marshall springs.
2. according to the described piston compressor of claim 1, it is characterized in that marshall springs is mounted obliquely between spring bracket and the crankcase.
