Abstract
The invention relates to a closed type rolling rotor compressor. The closed type rolling rotor compressor comprises a compressor body used for compressing a refrigerant propane R290, wherein a cylinder and a motor are arranged in the compressor body; the height H of the cylinder is 10 to 30 millimeters and the inner diameter D of the cylinder is 30 to 40 millimeters; a piston is arranged in the cylinder and is sleeved on a curved part of a crankshaft; a main bearing and a secondary bearing corresponding to a main shaft and a secondary shaft at the two ends of the crankshaft are arranged at the two ends of the cylinder; the main shaft is in transmission connection with the motor; the diameter d1 of the main shaft is 11 to 13 millimeters; and the diameter d2 of the secondary shaft is 9.5 to 11 millimeters. The working pressure (pressure differential) of the R290 compressor is less than that of the R22 compressor, so the axle load of the R290 compressor is less than that of the R22 compressor, and the crankshaft outer diameter value of the R290 compressor can be less than that of the R22 compressor. The closed type rolling rotor compressor has the advantages that: the crankshaft outer diameter of the R290 compressor is reduced, so friction power consumption of the crankshaft in the working process is reduced correspondingly, the mechanical efficiency of the compressor is improved, and energy efficiency of the compressor is improved.
Description
Technical field
The present invention relates to a kind of compressor, particularly a kind of closed type rolling rotor compressor that is primarily aimed at compression R290 (propane) refrigeration agent.
Background technique
The R22 refrigeration agent is classified as the refrigeration agent that time limit is progressively eliminated by " Montreal is agreed " book.Europe, Japan begin to turn to the R410A refrigeration agent to substitute already, and the U.S. also will forbid that in 2010 R22 uses in new refrigeration product.China has also accelerated the paces that R22 eliminates, and will be frozen in the average level in 2009～2010 years in 2013, will reach 10% the requirement of cutting down baseline values in 2015.And more domestic main brand also begin to release the environment-friendly air conditioner of R410A as refrigeration agent.Yet the GWP value of R410A is also bigger than R22, and " Kyoto Protocol " classified R410A as the greenhouse gases of controlled discharge, and all R410A never are long-range replacement schemes.
As HCFC (like R22), the alternative refrigerant of HFC (like R410A, R407C)), existing carbon-hydrogen refrigerant industry is the most paid close attention to.The carbon-hydrogen refrigerant that wherein is used for air conditioner, what Application Research was the widest at present is exactly R290 (propane).And the existing closed type rolling rotor compressor (R290 compressor) that refrigeration agent propane R290 is carried out processed compressed generally comprises compressor block; Be provided with cylinder and motor in the body; The cylinder height H is 10mm～30mm, 22mm～26mm, 27mm～35mm, 20mm～30mm, 20mm～40mm, 26mm～44mm or 28mm～50mm; Each specification of the corresponding cylinder height H of cylinder bore diameter D value respectively is 30mm～40mm, 41mm～50mm, 41mm～50mm, 51mm～58mm, 54mm～57mm, 58mm～63mm and 64mm～70mm; Be provided with piston in the cylinder; And be set on the pars convoluta of bent axle; The main shaft and the countershaft of the corresponding crankshaft two end in two ends are provided with main bearing and supplementary bearing, and main shaft is connected with electric-motor-driving, and each combination specification of main shaft diameter d 1 corresponding cylinder height H and cylinder bore diameter D value respectively is 14.5mm, 16mm, 18mm, 18mm, 20mm, 21mm and 22mm; Each specification of countershaft diameter d 2 corresponding main shaft diameter d 1 value respectively is 12.5mm, 14mm, 15mm, 16mm, 18mm, 18mm and 20mm; The main shaft of its bent axle and countershaft external diameter are bigger, and the friction power loss of bent axle also can correspondingly increase in the working procedure, and the mechanical efficiency of compressor is descended.
Summary of the invention
The object of the invention aim to provide a kind of simple and reasonable, mechanical efficiency is higher, the closed type rolling rotor compressor of energy-conserving and environment-protective, to overcome deficiency of the prior art.
A kind of closed type rolling rotor compressor by this purpose design; Comprise the compressor block that refrigeration agent propane R290 is carried out processed compressed, be provided with cylinder and motor in the body, be provided with piston in the cylinder; Piston sleeve is located on the pars convoluta of bent axle; The main shaft and the countershaft of the corresponding crankshaft two end in cylinder two ends are provided with main bearing and supplementary bearing, and main shaft is connected with electric-motor-driving, it is characterized in that: the corresponding relation such as the following table of cylinder height H, cylinder bore diameter D, main shaft diameter d 1 and countershaft diameter d 2: unit is mm
The working pressure (pressure reduction) that the present invention considers the R290 compressor is low about 10%～20% than the R22 compressor, so the thrust load of R290 compressor is also than R22 compressor low about 10%～20%.Therefore, the bent axle external diameter of R290 compressor can be littler than the value of R22 compressor.Its beneficial effect is that the bent axle external diameter of R290 compressor reduces, and then the friction power loss of bent axle also can correspondingly reduce in the working procedure, and the mechanical efficiency of compressor is improved, and reaches the purpose that improves the compressor efficiency.Its simple and reasonable, energy-conserving and environment-protective.
