Description
Technical field
The present invention relates to rotor-type compressor, especially relate to a kind of rotor-type compressor.
Background technique
Present common rotor formula compressor assembling mode is: compressor pump assembles separately, then cold pressing or hot jacket rotor, clearance gauge is used the pump housing and stator to be assembled, subsequently by complete for housing hot jacket, inlet pipe connection is installed, then the welding of upper cylinder cover or cylinder is carried out, finally welding upper lower cover, liquid-storage container.
The structure Problems existing of this common rotor formula compressor is mainly as follows:
(1) common rotor compressor is mostly cylinder welding or upper cylinder cover welding, and the heat of welding causes thermal distortion, has a certain impact to the coaxality of compressor.
(2), during the assembling of common rotor compressor, the coaxality of stator and upper cylinder cover not easily ensures, rotor gap is uneven.
(3), when inlet pipe connection installed by common rotor compressor at cylinder place, easily eccentric slot is had an impact.
(4) common rotor formula compressor, no matter how inlet pipe connection and intakeport are installed, or highi degree of accuracy is processed, always have the hidden danger of internal leakage, as shown in Figure 1, be high pressure in compressor, be low pressure in cylinder 6, owing to having gap in upper cylinder cover 14, cylinder 6 and compressor housing 13, in pressurized gas and cylinder there is very large pressure reduction in low-pressure gas, if and poor sealing between inlet pipe connection 10 and intakeport 11, then pressurized gas directly will enter intakeport from gap, and this kind of situation has had a strong impact on the efficiency of compressor.
Summary of the invention
Object of the present invention is exactly provide a kind of coaxality high to overcome defect that above-mentioned prior art exists, rotor gap uniformity, and when installing inlet pipe connection, does not have an impact to the eccentric slot of the pump housing, without the rotor-type compressor of interior leakage hidden danger.
Object of the present invention can be achieved through the following technical solutions: a kind of rotor-type compressor, comprise upper casing cover cap, stator, rotor, bent axle, housing, upper cylinder cover, cylinder, piston, blade, lower cylinder cap, lower casing cover cap, inlet pipe connection, it is characterized in that, described upper cylinder cover and housing unite two into one, and once-through is integrated open frame, the top of this integral type frame is provided with concave station in, this interior concave station is provided with concave station plane in, and the lower end of described stator is fixed in interior concave station plane; Described integral type frame is provided with intakeport, and this intakeport one end is arranged on the side of integral type frame, and the other end is arranged on the surface of contact of integral type frame and cylinder, and described inlet pipe connection static pressure enters in intakeport, with intakeport interference fit.
Described stator is fixedly connected with by viscose glue or bolt with interior concave station plane.
Described integral type frame is by casting once-through.
Described integral type frame is formed by metal material processing.
It is cast iron that described metallic material is dropped in the bottom of stator.
The gap solder of described intakeport and inlet pipe connection seals.
Described bent axle and piston are integrated, and described blade is ceramic blade.
The top of described integral type frame is connected with upper casing cover cap.
The bottom of described integral type frame is connected with lower casing cover cap.
Described integral type upper cylinder cover and upper casing cover cap, lower casing cover cap are by weld or viscose glue is connected.
Compared with prior art, rotor-type compressor of the present invention, decreases the parts of compressor.Upper cylinder cover is integrated with housing to be processed, stator is directly installed on the step plane on upper cylinder cover, use adhesive is fixed, stator is arranged on this step-like platform, can effectively stop it to move radially, stator is located, thus the problem of coaxality between upper cylinder cover and stator can be ensured well, avoid hot jacket high temperature to produce the impact of thermal distortion to stator, also have good guarantee to the gap between rotor.
This construction rotor compressor, cancel piston element, bent axle is integrated with piston, effectively reduces the structure member of rotor compressor, and bent axle surface adopts specific coatings to cover, and blade uses special ceramics to make, and ensure that the reliability of component.
This structure can not need the welding carrying out upper cylinder cover or cylinder, reduces the processing of compressor, installation step, conserve space.
Synthesis parts are directly cast or processed to this construction rotor formula compressor housing and upper cylinder cover, is connected, as the intakeport of compressor, therefore can solves the problem of interior leakage well at the side of these parts and punching with cylinder contact face.Because compressor air suction mouth is not exposed in pressurized gas with the section of cooperation of inlet pipe connection, and compressor is when freezing liquid-storage container, gap solder in intakeport and inlet pipe connection can be sealed, therefore there is not the problem of interior leakage completely, inlet pipe connection is directly connected with described integral type frame, can not produce the former cylinder that now assembles and integral type frame relative position and offset, therefore can not impact the bias of compressor completely, the situation causing eccentric slot to run mistake when installing inlet pipe connection can be avoided well to occur.
On this construction rotor compressor, lower cover carries out connecting with adhesive or laser welds, and can effectively avoid using high temperature during electric welding to produce deformation effect to compressor.
