Abstract
The utility model discloses a natural cooling CNG compressor with no auxiliary cooling channel comprising a cylinder component constituted by four ranges of a first-grade cylinder, a second-grade cylinder, a third-grade cylinder and a forth-grade cylinder, a cylinder sealing component, an operating structure and a motor for driving a piston of the cylinder, and a pipeline and valves, wherein the diameter of the first grade cylinder is 84-120 mm, the lambda between the stroke of the first-grade cylinder and the diameter being 0.5-1.3. The optimization design of the utility model greatly increases synchronous rotating speed and also reduces decreasing temperature, thus achieving natural cooling without auxiliary cooling channel. The utility model has several advantages over prior art technology, such as a larger cylinder volume, a larger air flower area, a higher displacement, an energy-saving power, combined with a lower manufacturing and maintaining difficulty of the cylinder and a less processing work.
Description
Technical field
The utility model relates to the auxiliary cooling water channel natural cooling CNG compressor of a kind of nothing.
Background technique
Existing C NG compressor comprises by first-stage cylinder, secondary cylinder, and three grades of cylinders, the level Four cylinder is the cylinder assembly and the cylinder body black box of the differential composition of level Four altogether, and the fuselage and the motor that drive the motion of cylinder piston, also comprises the pipeline and the valve that connect above-mentioned parts.When the driven by motor motion rotated, piston is driven to do reciprocating linear motion in cylinder carried out gas compression.Motion is realized lubricated by oil pump and oil gun that chain-driven drives lubrication system.Existing its piston of CNG compressor is in cylinder body during the to-and-fro motion pressurized gas, can produce a large amount of heats and pass to cylinder body, for fear of phenomenons such as the too high tile kilning that causes of temperature, scuffings of cylinder bore, must cool off compressor casing, the conventional type of cooling all is to adopt water cooling (cylinder body attaches water channel) or air cooling (cylinder body adds fin).But such type of cooling has not only increased the manufacture difficulty of cylinder body, and is time-consuming, and maintenance is also inconvenient.And, limited volume of cylinder because the cylinder volume is bigger, reduced the air flue circulation area.
Summary of the invention
The purpose of this utility model is: at the problem of above-mentioned existence, provide a kind of CNG compressor of making the auxiliary cooling water channel natural cooling of the nothing simple, that processing is easy to maintenance, discharge capacity is big, efficient is high.
The compressor that the utility model adopts comprises by first-stage cylinder secondary cylinder, three grades of cylinders, the cylinder assembly of the differential composition of level Four cylinder level Four, cylinder body black box, and the fuselage and the motor that drive the motion of cylinder piston also comprise the pipeline and the valve that connect above-mentioned parts; The diameter of described first-stage cylinder is 84-120mm, and the stroke of first-stage cylinder and diameter ratio λ are 0.5-1.3.
Further improving is that the diameter of described one-level cylinder body is 90 mm.The piston average running speed Vm=2.2 m/s of one-level cylinder body particularly.
Further improving is that the diameter of described one-level cylinder body is 108mm.The piston average running speed Vm=1.77 m/s of one-level cylinder body particularly.
The utility model compressor design thinking adopts high rotating speed, pressurized gas waiting time in cylinder is very short, the heat that gas compression produces has little time to pass to cylinder body (or having only heat seldom to pass to cylinder body), pressurized gas has been discharged outside the cylinder body, the cylinder body temperature rise is little, can in the temperature range that allows, reach thermal equilibrium, therefore make the CNG compressor casing realize natural cooling design (being that cylinder body did not both have air-cooled fin in the no-cooling-water road yet).Owing to saved the redundant annex of cylinder cooling, the cylinder body of so same volume size can design bigger volume of cylinder and bigger air flue circulation area, help improving discharge capacity and save power, also reduced the manufacturing and the maintenance difficulty of cylinder body simultaneously, reduced amount of finish.But improve rotating speed, be subjected to the restriction of many factors, the most directly will consider that two big factors are arranged: ratio λ=S/D of (1) stroke S and one-level cylinder diameter D; (2) mean piston speed Vm.My company takes optimal design, and the diameter of first-stage cylinder is 84-120mm, when being 0.5-1.3 as the stroke of 90mm, 108mm and first-stage cylinder and diameter ratio λ, can realize high rotating speed under the prerequisite that guarantees life of equipment.Especially be Vm=2.2 m/s or 1.77 m/s in mean piston speed, when the diameter of corresponding first-stage cylinder was 90mm or 108mm, effect was best.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is done detailed explanation.
In order to make the purpose of this utility model, technological scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification 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.
The CNG compressor of the auxiliary cooling water channel natural cooling of nothing as shown in Figure 1 comprises by first-stage cylinder 1, secondary cylinder 2, three grades of cylinders 3, the cylinder assembly of the differential composition of level Four cylinder 4 level Four, the cylinder body black box, and the motion 5 and the motor 6 that drive cylinder piston, also comprise the pipeline and the valve that connect above-mentioned parts; The diameter of first-stage cylinder is 84-120mm, and the stroke of first-stage cylinder and diameter ratio λ are 0.5-1.3.
The claimant is at the CNG compressor of the auxiliary cooling water channel natural cooling of nothing of the DTY of its exploitation series D type 150 types and two series of 300 types, and synchronous speed is respectively 1500r/m and 1000r/m, domestic initiation.High rotating speed has brought high efficiency.Because compressor rotary speed improves, the time of every single compression work shortens greatly.Under the identical situation of unit time internal leakage, the single compression work time shortens greatly, leaks total amount and significantly reduces, and discharge capacity strengthens, and efficient improves.In order to realize high rotating speed, the stroke of the first-stage cylinder of compressor and diameter ratio λ are 0.5-1.3, and the diameter of 150 first-stage cylinder is 90mm, and mean piston speed is Vm=2.2 m/s.The diameter of 300 type first-stage cylinder is 108mm, and mean piston speed is Vm=1.77 m/s.Do not disposing under the situation of cooling attachment, its row's temperature is respectively 100 ℃ and 88 ℃.Can be in the effect that guarantees to realize high rotating speed under the prerequisite of life of equipment and need not auxiliary cooling water channel natural cooling.
To be the claimant be engaged on the basis that gaslift gas production, underbalance well-digging manufacture and design with the high speed and high pressure gas compressor summing up CNG compressor bank for many years that do not have auxiliary cooling water channel natural cooling, again in conjunction with China's actual conditions, the high speed CNG compressor with Chinese characteristics of initiative, have rotating speed height, efficient height, big, steady, the advantages such as volume is little, convenient operating maintenance that turn round of discharge capacity, will start new chapter for the development of CNG industry.
