Abstract
The utility model discloses a natural gas compressor. The natural gas compressor comprises a motor (1), a crankcase (2) and inverted stage differential type cylinder whole bodies each composed of a first stage cylinder (3a) and a second stage cylinder (3b), wherein the output shaft of the motor (1) is connected with the crankshaft in the crankcase (2). The natural gas compressor is characterized in that the crankcase (2) are equipped with two inverted stage differential type cylinder whole bodies, and the two inverted stage differential type cylinder whole bodies are disposed on two opposite side faces of the crankcase (2) respectively. With the adoption of the abovementioned technical scheme where two inverted stage differential type cylinder whole bodies are disposed on two opposite side faces of the crankcase (2) respectively, movement mass of the two sides is equal, and thus the complete machine is stable in operation and small in vibration.
Description
Technical field
The utility model relates to a kind of natural gas compressor.
Background technique
Present natural gas compressor comprises crankcase, distribution one-level cylinder and secondary cylinder on crankcase, one-level cylinder and secondary cylinder are arranged in the relative both sides of crankcase, one-level cylinder and secondary cylinder all adopt double-action, because the first stage piston quality is much larger than the second piston quality, cause the moving-mass of crankcase both sides different, thereby cause that the complete machine operational shock is big, stationarity is relatively poor.
The model utility content
In order to solve the problems of the technologies described above, the utility model provides a kind of and turns round steadily, the little natural gas compressor of vibration.
To achieve these goals, the technical solution of the utility model is as follows: a kind of natural gas compressor, comprise crankcase (2), one-level cylinder (3a) and secondary cylinder (3b), one-level cylinder (3a) and secondary cylinder (3b) adopt the cylinder of falling stage differential style overall structure, be furnished with two cylinder of falling stage differential style integral body on the described crankcase (2), described two cylinder of falling stage differential style integral body lay respectively on two relative sides of crankcase (2).
Adopt technique scheme, one-level cylinder and secondary cylinder adopt the cylinder of falling stage differential style overall structure, and two cylinder of falling stage differential style integral body lay respectively on the opposite flank of crankcase, and the moving-mass of the moving element of these both sides is equal fully, thereby make that the complete machine running is more steady, vibrate little.
In technique scheme: also comprise motor (1), described motor (1) is positioned at the neutral position of the right part of prizing at the bottom of the compressor, described crankcase (2) is positioned at the neutral position of prizing left part at the bottom of the compressor, bent axle in the output shaft of described motor (1) and the crankcase (2) is connected, and two cylinder of falling stage differential style integral body are contained in respectively on the forward and backward side of crankcase (2).
In technique scheme: also comprise air inlet knock out drum (8), two one-level coolers (4), two secondary coolers (5), two primary separators (6) and second-stage separator (7), one of them one-level cooler (4) and a secondary coolers (5) are contained in the front side of motor (1) side by side, another one-level cooler (4) and another secondary coolers (5) are contained in the rear side of motor (1) side by side, described air inlet knock out drum (8) is contained in the left back portion of prizing at the bottom of the compressor, two gas outlets of described air inlet knock out drum (8) are communicated with the suction port of the one-level cylinder (3a) of two cylinder of falling stage differential style integral body respectively, the air outlet of described one-level cylinder (3a) is communicated with the suction port of its close one-level cooler (4), the air outlet of described one-level cooler (4) is communicated with the suction port of its close secondary cylinder (3b) by a primary separator (6), the air outlet of described secondary cylinder (3b) is communicated with the suction port of its close secondary coolers (5), and the air outlet of all secondary coolers (5) all is communicated with the suction port of second-stage separator (7).
One of them one-level cooler and secondary coolers are contained in the front side of motor side by side like this, another one-level cooler and secondary coolers are contained in the rear side of motor side by side, compact structure, take up room little, and this Placement realizes air inlet in parallel, compression exhaust cools off respectively, has finally realized exhaust in parallel, this makes that the pipeline structure of compressor is simpler, is easy to maintenance.
Beneficial effect: the utility model is reasonable in design, simple in structure, pipeline structure simple, be easy to maintenance, and complete machine operates steadily, and vibrates little.
