Abstract
The utility model discloses a cylinder body for compressors. The cylinder body comprises a cylinder hole, and is characterized in that a cavity forming a first stage exhausting and muffling cavity is formed on the cylinder body below the cylinder hole; and small holes used for exhausting gas are formed in the first stage exhausting and muffling cavity. The utility model can meet the requirements of reducing vibration and noise level of a compressor while reducing manufacturing cost.
Description
Technical field
The utility model relates to the exhaust cavity of Reciprocting piston compressor, particularly for the improvement of first order silencing cavity structure on the compressor casing.
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, left side or the right side in cylinder body cylinder hole designed in first order exhaust noise silencing chamber usually, or on the left of behind the cylinder body cylinder head or right side, the gas of compressor is drained in the cylinder head hyperbaric chamber after compression earlier, connection is drained into first order exhaust noise silencing chamber through the aperture on the valve plate, connects through small holes to be drained into exhaust noise silencing chamber, the second level or directly discharge again.These first order exhaust noise silencing chambeies need processing separately, have increased cost for manufacturing compressor.
The model utility content
The purpose of this utility model is: at the prior art deficiency, provide a kind of manufacturing simple, can reduce the vibration of compressor air-discharging pulsation generation and the compressor casing of noise figure.
The technical solution of the utility model is:
A kind of compressor casing comprises the cylinder hole, it is characterized in that: a cavity is arranged on the cylinder body below the cylinder hole, and this cavity constitutes first order exhaust noise silencing chamber, has in first order exhaust noise silencing chamber and discharges the aperture that gas is used.
The supplementary technology scheme of model utility is as follows:
Preferably, described cavity is equal apart from the distance in cylinder hole near the upper edge in cylinder hole.
Preferably, described cavity is the blind hole of 3 connections, and 3 blind holes become waist shape to distribute round center, cylinder hole.
Preferably, described cavity is the waist shape blind hole around center, cylinder hole.
Preferably, described aperture is the hole in cylinder interior, and this hole is positioned at the cavity bottom, and is communicated with first order exhaust noise silencing chamber and exhaust noise silencing chamber, the second level.
Preferably, described aperture is the cylinder surface processing groove, and this processing groove is communicated with first order exhaust noise silencing chamber and exhaust noise silencing chamber, the second level.
Preferably, described aperture is the cylinder surface processing groove, and this processing groove is communicated with first order exhaust noise silencing chamber and compressor outside
The beneficial effects of the utility model are: can reach the requirement that reduces vibration of compressor and noise figure when reducing manufacture cost; Adopt the volume that can under the prerequisite that guarantees cylinder strength, increase cavity around the cavity form of cylinder pore size distribution; Adopt the form of the blind hole of 3 connections directly to process cavity with the mode of holing man-hour adding, further saved man-hour and cost; Constituting aperture can further facilitate processing and save man-hour in the hole of cylinder interior.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is a compressor casing embodiment's of the present utility model left view.
Fig. 2 is the plan view of compressor casing shown in Figure 1.
Wherein, reference character: 1 is cylinder body, and 2 is the cylinder hole, and 3 is first order exhaust noise silencing chamber, and 4 is aperture, and 5 is exhaust noise silencing chamber, the second level.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Specific embodiment of the utility model, as depicted in figs. 1 and 2, a kind of compressor casing, similar with existing housing structure, improvements mainly with the structure in its first order exhaust noise silencing chamber, concrete structure is as follows: the first order exhaust noise silencing chamber 3 that forms with 3 blind holes that are connected below the cylinder hole 2 of cylinder body 1 is connected to exhaust noise silencing chamber, the second level 5 (exhaust noise silencing chamber, the second level is connected to form capping and cylinder body by screw) by the aperture in the cylinder body 4 again.
When the cylinder hole 2 of refrigerant gas through cylinder body 1, through Piston Compression, form the gas of High Temperature High Pressure, at first be drained in the cylinder head hyperbaric chamber through the exhaust port on the valve plate, connect through the aperture on the valve plate again and be drained into first order exhaust noise silencing chamber 3 (reducing the exhaust pulsation for the first time), be drained into exhaust noise silencing chamber, the second level 5 (reducing the exhaust pulsation for the second time) through small holes 4 connections again, can reduce vibration of compressor and noise figure.
A kind of compressor casing comprises the cylinder hole, it is characterized in that: a cavity is arranged on the cylinder body below the cylinder hole, and this cavity constitutes first order exhaust noise silencing chamber, has in first order exhaust noise silencing chamber and discharges the aperture that gas is used.
Specific embodiment of the utility model 2, a kind of compressor casing, its structure is similar to Example 1, but described cavity is a waist shape blind hole around center, cylinder hole, and waist shape blind hole upper edge is equal apart from the distance in cylinder hole.
Specific embodiment of the utility model 3, a kind of compressor casing, concrete structure is as follows: the first order exhaust noise silencing chamber 3 that forms with 3 blind holes that are connected below the cylinder hole 2 of cylinder body 1, at the cylinder surface processing groove, this processing groove is communicated with first order exhaust noise silencing chamber and exhaust noise silencing chamber, the second level, and perhaps this processing groove directly is communicated with first order exhaust noise silencing chamber and compressor outside.
Disclosed all features in this specification, or the step in disclosed all methods or the process except mutually exclusive feature and/or step, all can make up by any way.
Disclosed arbitrary feature in this specification (comprising any accessory claim, summary and accompanying drawing) is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or the similar characteristics.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
