Description
Technical field
The utility model relates to gas dynamic facility (GDF) technical field, is specifically related to a kind of novel crosshead device.
Background technique
Compressor occupies important position in the universal machine field of China, and in universal machine power consumption accounting, compressor accounts for 40%.Significant in the equipment manufacture of China to the Continual Improvement of compressor set thus, be particularly the energy-conservation technological invention carried out and improvement at compressor field, the energy-saving and emission-reduction of country had to the meaning of strategy.
Reciprocating-piston compressor is the topmost main force in compressor family, because reciprocating-piston compressor can compress the various gas of conveying, as toxic and harmful, without oil gas body, pressure range, from low pressure to ultrahigh pressure, is that any other compresses and all can not reach.So reciprocating-piston compressor is main force's equipment of universal machine, it is main force indispensable in China's equipment manufacture.Therefore, it is very necessary for carrying out Continual Improvement to each structure of reciprocating-piston compressor.
Crosshead device is one of very important parts in reciprocating-piston compressor, it is the key device of linear reciprocating motion by convert rotational motion, achieve cylinder air-breathing, compression, exhaust therefrom, realize the compression to gas and conveying, along with the rotation of compressor crank shaft, transporting compressed gas body at regular time and quantity.Therefore the quality of crosshead device be directly connected to the motion of reciprocating compressor whether steadily, whether reliably run, whether noise-and-vibration-reduction energy-saving and cost-reducing.Reciprocating-piston compressor crosshead device in the past, the following problem of existence:
Component are many, and fabricating cost is higher;
Volume is comparatively large, the also corresponding increase of middle body slideway, body material in waste;
Reciprocation mass is large, and inertial force is large, and frictional work is large, and power consumption increases;
Complex structure, reliability reduces, and maintain and replace is complicated.
Model utility content
The purpose of this utility model is to make up the deficiencies in the prior art, provides the novel crosshead device that a kind of structure simplifies more.
In order to reach the purpose of this utility model, technological scheme is as follows:
A kind of novel crosshead device, comprise crosshead body and crosshead pin, it is characterized in that, described crosshead pin is provided with dowel hole, dowel hole is provided with the key connecting described crosshead body and crosshead pin, described crosshead body is provided with the first oil through, and crosshead pin is provided with the second oil through, and described first oil through is communicated with the second oil through.
Further, the afterbody of described crosshead pin is provided with the crosshead pin nut of being locked by crosshead pin.
Further, the afterbody of described crosshead pin is also provided with the cotter pin for locating described crosshead pin nut.
Further, the middle part of described crosshead pin is provided with oil duct, and described oil duct is communicated with the second oil through.
Further, one end of described oil duct is placed in crosshead pin inside and is what close, and the other end has the opening being communicated with crosshead pin end face, is provided with plug screw at opening.
Further, described crosshead body is also provided with the spreader groove of annular, described first oil through is communicated with described spreader groove.
The beneficial effect that the utility model has:
By ganging up bolt or crosshead pin cap fixes crosshead pin mode by traditional crosshead pin, change to and by increasing a metallic bond, crosshead pin and crosshead are fixed, make them not produce relative movement, this modified node method can be widely used in Reciprocting piston compressor.
By changing the means of fixation between crosshead body and crosshead pin, greatly simplify also structural type, new structural type has following features:
Volume is little, and reciprocation mass is little, and inertial force and frictional work reduce, energy-saving and cost-reducing;
Structure is simple, and manufacture cost reduces;
Crosshead device overall volume reduces, and saves space, can reduce the size of body in slideway, reduces the cost of material of complete machine further;
Component are few, and maintenance is reliable, convenient maintenance and replacement.
