Description

Diesel engine directly drives energy-saving air compressor

The utility model relates to and a kind ofly is used for the mining operation, and directly by diesel-driven air compressor.

Technical background of the present utility model is former L type (10m ³) air compressor, it is electrodynamic type, double-action, two stage compression, water-cooling type air compressor.The shortcoming of this compressor is because two crosshead slideways on the fuselage are L type structure, machine center of gravity in dynamic and static balance is partial to body one side all the time, cause body vibration in service bigger, power consumption also strengthens relatively, in addition because the secondary cylinder body is horizontally-arranged fully, the same casing wall of piston ring in the machine run, piston rod are bigger with crosshead body surface friction drag with cylinder seat center hole and slideway, thereby have increased energy consumption.While L type (10m ³) the air compressor air displacement is little, and the dependence electric drive, it is very inconvenient to use for electric power shortage or abnormal area that powers, as just inapplicable to the mining operation in mountain area, field.

Goal of the invention of the present utility model is to overcome above-mentioned the deficiencies in the prior art part and provides that a kind of vibration is little, power consumption is few, and is suitable for that electric power lacks or use in the undesired area that powers, particularly the energy-saving air compressor that needs of the open-air mining operation in mountain area.

Goal of the invention of the present utility model is achieved by the following technical programs: the basic comprising that it has is 1. to be fixed in the base and the fuselage of one; 2. bent axle, connecting rod, crosshead body linkage, by be loaded on the same bent axle two connecting rods respectively with I and II cylinder seat on two crosshead bodies be slidingly matched and connect; 3. be I and II cylinder seat, the cylinder cap assembly of Bolt Connection, comprise respectively and have double-acting I and II cylinder body, I and II suction valve group, I and II outlet valve group, I and II piston piston rod assembly, I and II stuffing box; 4. be water cooler, oil injecting lubricating device and the power connection set of Bolt Connection.Characteristics of the present utility model are the V-shaped structure setting of two crosshead slideways (24) on the fuselage (1), cooler 12 places between the first-stage cylinder seat 19 and secondary cylinder seat 8 of fuselage 1 top, in cooler 12, be provided with multiple row water-cooled heat exchanging tube and big volume one-level exhaust cavity, in the one-level exhaust cavity, be provided with spoiler 23, to reduce airspeed, make the heat exchange cooling fully.In the power connection set, comprise: clutch 33, coupling 34, coupling pin 35, air compressor flywheel 37.Air compressor flywheel 37 links with coupling 34 by the coupling pin 35 that is lined with flexible rubber ring 36, and coupling 34 links with the coupling shaft axle head of clutch 33.The tilt angle of the center line of two crosshead slideways 24 on the fuselage 1 and fuselage 1 horizontal position is respectively 45 ° and 135 °.This is the optimal selection that the utility model is obtained V-structure.Its first stage piston 15 adopts aluminum alloy to make simultaneously, and second piston 6 adopts cast iron to make.To satisfy the weight ratio of optimum organization I and II piston.

The utility model advantage compared to existing technology is: the first, owing to adopt the V-type type, so machine gravity is good to neutrality, the corresponding reduction of center of gravity, after optimum organization I and II piston weight compares, the dynamic balancing that machine is in operation be improved significantly.Thereby vibration is obviously reduced; V-type machine machine friction resistance in movement process also has reduction significantly on the other hand; The second, interstage cooler has strengthened the air cavity volume of one-level exhaust, increases the columns of water-cooled heat exchanging tube, installs spoiler additional simultaneously in the one-level exhaust cavity, reduces airspeed, makes the heat exchange cooling fully, so the complete machine idle work of doing in service significantly reduces.Test result shows that synthesis energy saving effect of the present utility model can reach about 30%; Three, owing to adopt diesel engine directly to drive, be applicable to that electricity consumption is inconvenient or use in abnormal area that powers, provide convenience in particular for the mining operations in mining area.

Embodiment: this specification the 5th part and 1-3 is clear has in conjunction with the accompanying drawings described embodiment of the present utility model, so do not repeat.Now be described in further detail installing and using of it in conjunction with the accompanying drawings: with 12M ³The V-type air compressor be example, as shown in Figure 3, diesel engine (selecting the 6135-G type for use) is installed on respectively on the same base with air compressor, use bolton, to guarantee that coupling is with flywheel center unanimity.With clutch separation, earlier with diesel engine starting and after reaching certain rotating speed, clutch closes before starting, make its common running, outside air enters into cylinder cap, cylinder seat by a cylinder import, when piston stroking upward, cylinder seat exhaust valve closure, INO, outside air enters inferior part of the cylinder block; Then be that suction valve cuts out on the cylinder cap, after the piston upper gas reached certain pressure, outlet valve was opened, and pressurized air enters interstage cooler by cylinder body flange place; And during descent of piston, then opposite with above-mentioned action, the exhaust valve closure on the cylinder cap, INO, gas enter cylinder body top by suction valve; Cylinder seat place then is that suction valve cuts out, when pressure reaches certain numerical value, exhaust valve opening, pressurized air is discharged by outlet valve, the place enters interstage cooler by the cylinder body flange, pressurized air after interstage cooler cooling, enter two cylinder (same cylinder effect is identical) compression again after, discharge that to enter gas holder standby.

In the running, oil pump is directly given bent axle, connecting rod, crosshead body and slideway pump oil lubrication from the oil sump of fuselage bottom, the I and II cylinder body then is lubricated by the direct oiling of oil gun, and the water cooling aspect is then cooled off cooler I and II cylinder body, cylinder cap, cylinder seat respectively by cooling water.
