Abstract
The utility model relates to a oil -injected screw air compressor machine provides a lower pressure air compressor machine, including the host computer, the host computer include the casing and set up to be in the casing in the screw rod, the casing on be equipped with air inlet and the gas outlet that is linked together with the casing inner chamber, its characterized in that: the diameter L1 of screw rod does with length L2's proportion: L1: L2=1: 1.2~1.55, the diameter L3 of air inlet does with the diameter L1's of screw rod proportion: L3: L1=1: 1.3~1.5, the diameter L4 of gas outlet does with the diameter L1's of screw rod proportion: L4: L1=1: 1.4~1.9. The utility model discloses an operation of greater trochanter slow -speed of revolution mode has been optimized and has been inhaled exhaust pipe, at 0.3~0.5Mpa's discharge pressure within range, can both keep best specific power, will the specific power is compared with the like product hang down 2 3kW (m3min) has reached furthest and has reduced air compressor machine inside pressure loss and leakage to reach energy -conserving mesh. High -efficient reliability service for pressing the air compressor machine provides strong assurance.
Description
Technical field
This utility model relates to exhaust end base of oil injection threaded bolt air compressor machine.
Background technology
The rated pressure of general fuel injection helical lobe compressor is general all 0.7～1.25mpa, and uses pressure≤0.5mpa
Air compressor machine be known as relatively low pressure air compressor.
The gas equipment of some user needs pressure limit in the compressed air of 0.3～0.5MPa, can normally work.But
All use the air compressor machine of 0.7mpa pressure when being and select air compressor machine, then make pressure subtract by approach such as air relief valve and get off for gas
End uses.It can be said that the air pressure that user uses is 0.3Mpa～0.5mpa, bear is but the power consumption of 0.7Mpa.
According to the moving law of screw air compressor, pressure at expulsion often reduces 1bar, and energy consumption is by reduction about 7%.Depend on
Secondary reckoning, 5bar screw air compressor is when running than 7bar screw air compressor capable of reducing energy consumption about 14%.
As can be seen here, the main frame of pneumatics directly determines the operating cost of air compressor machine, selects relatively low pressure screw air compressor
Compressed-air actuated gas production can be increased considerably under same power of motor, correspondingly can be with power saving 20-30%.
Utility model content
The purpose of this utility model is to provide one relatively low pressure air compressor, to meet the needs of association area application.
Described relatively low pressure air compressor, including main frame, described main frame includes casing and is arranged in described casing
Screw rod, described casing is provided with the air inlet and gas outlet being connected with chassis cavity, it is characterised in that:
The diameter L1 of described screw rod with the ratio of length L2 is:
L1: L2=1: 1.2～1.55；
The diameter L3 of air inlet with the ratio of the diameter L1 of screw rod is:
L3: L1=1: 1.3～1.5；
The diameter L4 of gas outlet with the ratio of the diameter L1 of screw rod is:
L4: L1=1: 1.4～1.9.
The beneficial effects of the utility model are:
This utility model uses greater trochanter slow-speed of revolution mode to run, and optimizes suction and discharge pipeline, the row of 0.3～0.5Mpa
In the range of atmospheric pressure, (during the most former 250KW/0.7MPa air compressor machine one-level efficiency, specific power is can to keep optimal specific power
5.3kW(m3/ min), this utility model relatively low pressure air compressor 250Kw/0.3MPa specific power can reach 3.15kW (m3/ min)),
Specific power is compared with like product will low 2-3kW (m3/ min), reach to reduce the pressure within air compressor machine to greatest extent and damaged
Consumption and leakage, thus reach energy-conservation purpose.High efficient and reliable operation for pressure air compressor machine provides strong guarantee.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Detailed description of the invention
Seeing Fig. 1, described relatively low pressure air compressor, including main frame, described main frame includes casing and is arranged on described
Screw rod in casing, described casing is provided with the air inlet and gas outlet being connected with chassis cavity, it is characterised in that:
The diameter L1 of described screw rod 2 with the ratio of length L2 is:
L1: L2=1: 1.2～1.55, preferably 1: 2.5；
The diameter L3 of air inlet 3 with the ratio of the diameter L1 of screw rod 2 is:
L3: L1=1: 1.3～1.5, preferably 1: 1.4；
The diameter L4 of gas outlet 4 with the ratio of the diameter L1 of screw rod 2 is:
L4: L1=1: 1.4～1.9, preferably 1: 1.56.
