Description

Single-row multistage compressor general-purpose platform

Technical field

The utility model relates to Compressor Technology, particularly relates to a kind of technology of single-row multistage compressor general-purpose platform.

Background technique

Gas compressor is the equipment for generation of pressurized gas, and primarily of crankcase, and the multiple piston type cylinders be arranged on crankcase are formed, and in crankcase, be provided with bent axle, bent axle is provided with the many connecting rods for driving the piston movement in each cylinder.

In order to realize multistage compression flow and working pressure requirement, the patent No. is that the Chinese patent of CN2012102783187 discloses a kind of biserial multistage compressor general-purpose platform, low pressure stage cylinder in this patent can be directly installed on cylinder block and directly be driven by connecting rod, high pressure stage cylinder is arranged on cylinder block by switching cylinder and is indirectly driven by switching slide block, low pressure stage cylinder and high pressure stage cylinder can be arbitrarily arranged on arbitrary cylinder block, therefore according to the cylinder of different working condition requirements assembling different size, different compression flows and the requirement of working pressure can be realized.But what the cylinder in this patent adopted is that biserial lays mode, this biserial is laid mode and is made the thickness of crankcase larger, application area is narrow, cannot be applied in some have requirement environment to thickness, and in this biserial laying mode, the power transmission point of bent axle is divided into two groups in the axial direction, power transmission point in same group distributes along the circumference of bent axle again, make the power transmission of bent axle point compare dispersion, be unfavorable for exerting oneself of bent axle, thus reduce working efficiency.

Model utility content

For the defect existed in above-mentioned prior art, technical problem to be solved in the utility model is to provide one can realize multistage compression flow and working pressure requirement, and working efficiency is high, the single-row multistage compressor general-purpose platform that application area is wide.

In order to solve the problems of the technologies described above, the single-row multistage compressor general-purpose platform of one provided by the utility model, comprises crankcase, and multiple piston type cylinder, multiple switching cylinder; It is characterized in that:

Be provided with the bent axle of a rotation in described crankcase, the outer wall of crankcase is fixed with multiple cylinder block, and each cylinder block, along the circumferential defiled of bent axle, bent axle is pivoted with and each cylinder block many connecting rods one to one; Be provided with slide block of transferring in axial sliding in described switching cylinder, switching slide block is provided with piston rod;

Each cylinder is divided into low pressure (LP) cylinder, high-pressure cylinder two class by working pressure, during the assembling of low pressure (LP) cylinder wherein, is directly installed on cylinder block, and the direct pivot joint of connecting rod on the piston of low pressure (LP) cylinder and bent axle; During high-pressure cylinder assembling, be all arranged on cylinder block by switching cylinder, and the piston rod pivot joint of the piston of high-pressure cylinder and switching cylinder, the connecting rod pivot joint of transferring on the switching slide block of cylinder and bent axle.

The single-row multistage compressor general-purpose platform that the utility model provides, there is multiple cylinder rigging position, low pressure (LP) cylinder can be directly installed on cylinder block, bent axle is by the piston of connecting rod Direct driver low pressure (LP) cylinder, high-pressure cylinder is arranged on cylinder block by switching cylinder, bent axle drives the piston of high-pressure cylinder by the transmission of connecting rod and the conversion of switching cylinder, low pressure (LP) cylinder and high-pressure cylinder can be arbitrarily arranged on arbitrary cylinder block, can according to the cylinder of different working condition requirements assembling different size, realize different compression flows and the requirement of working pressure, and each cylinder block is along the circumferential defiled of bent axle, power transmission point is comparatively concentrated, circumference only along bent axle distributes, be beneficial to exerting oneself of bent axle, thus can increase work efficiency, and crankcase can do relatively thin, can to have in the environment of requirement thickness at some and apply, its application area is relatively wide.

Fig. 1 is the plan view of the single-row multistage compressor general-purpose platform of the utility model embodiment;

Fig. 2 is the sectional drawing after the single-row multistage compressor general-purpose platform of the utility model embodiment is cut open along the A-A line in Fig. 1.

Embodiment

Illustrate below in conjunction with accompanying drawing and be described in further detail embodiment of the present utility model, but the present embodiment is not limited to the utility model, every employing analog structure of the present utility model and similar change thereof, all should list protection domain of the present utility model in.

As Figure 1-Figure 2, the single-row multistage compressor general-purpose platform of the one that the utility model embodiment provides, comprises crankcase 1, and multiple piston type cylinder, multiple switching cylinder 2; It is characterized in that:

Be provided with the bent axle 5 of a rotation in described crankcase 1, the outer wall of crankcase 1 is fixed with multiple cylinder block, and each cylinder block, along the circumferential defiled of bent axle, bent axle 5 is pivoted with and each cylinder block many connecting rods 51 one to one; Be provided with slide block 21 of transferring in axial sliding in described switching cylinder 2, switching slide block 21 is provided with piston rod 22;

Each cylinder is divided into low pressure (LP) cylinder 3, high-pressure cylinder 4 liang of classes by working pressure, when low pressure (LP) cylinder 3 wherein assembles, is directly installed on cylinder block, and the connecting rod 51 directly pivot joint on the piston of low pressure (LP) cylinder 3 and bent axle; When high-pressure cylinder 4 assembles, be all arranged on cylinder block by switching cylinder 2, and piston rod 22 pivot joint of the piston of high-pressure cylinder 4 and switching cylinder 2, switching slide block 21 and connecting rod 51 pivot joint on bent axle of switching cylinder 2.
