Abstract
The invention designs a lubricating oil duct suitable for a high-speed large-power reciprocating piston type compressor in the mode of simultaneously inputting lubricating oil in two paths by aiming at the defect existing in the one-way lubrication of the lubricating oil duct of the reciprocating piston type compressor. The lubricating oil from a main oil duct is divided into two paths. While the lubricating oil is transmitted to the main bearing of a compressor body, a bent axle and a connecting rod big end bearing, the lubricating oil is also transmitted to a connecting rod small-end bearing, so that the service life of parts can be prolonged, and the working reliability of the whole compressor is improved.
Description
Technical field
The present invention is used for the high-speed high-power Reciprocting piston compressor, relates to the design and manufacturing technology field of Reciprocting piston compressor pressure lubricating oil duct.
Background technique
The high-speed high-power Reciprocting piston compressor, its rotation speed n=1000r/min, power P=6000kW, the collection that is mainly used in rock gas is failed supercharging, gas storage gas injection, is natural gas exploration and development, storage imperative equipment.Current natural gas boosting, adopt the complete dependence on import of high-speed high-power compressor defeated, gas injection; Existing homemade twin compressor power can reach 10000kW; And rotating speed has only 350r/min; Belong to the low speed reciprocal compressor, domestic present high-power reciprocal compressor is mainly used in Petrochemical Enterprises; Present domestic low speed reciprocal compressor because equipment volume is very huge, and heavy, therefore, thus all at the scene partial installation be inappropriate for the application of gas industry.
Domestic, external Reciprocting piston compressor group of producing at present comprises static part and moving element, and static part comprises fuselage, middle body, compression cylinder, lubrication system; Moving element comprises bent axle, connecting rod, piston rod, crosshead, piston, and bent axle is loaded in the fuselage, and connnecting rod big end and crankshaft journal link.For lubricated rotatable parts; The lubricated content of prior art comprises the fuselage main bearing; Bent axle; Connecting rod bottom-end bearing; Small end bearing; Lubricating system has forward lubricated; That is: with lubricant oil pump successively to main oil gallery; Main bearing; The bent axle upper oil hole; Connecting rod bottom-end bearing; Arrive small end bearing at last; The major defect of the lubrication order of this prior art is: owing to passed through three moving elements in front; So when lubricant oil arrives small end bearing at last; Oil pressure has descended more; Therefore can not make small end bearing obtain sufficient lubrication; Cause shorten the working life of small end bearing; Need great amount of time and change small end bearing, therefore cause stopping of production; Another kind of prior art is a reverse-lubricating; That is: with lubricant oil pump successively to small end bearing, connecting rod bottom-end bearing, fuselage main bearing; Arrive the crankcase oil sump at last; The shortcoming of this mode and forward are lubricated similar; Because oil pressure descends, make that the last fuselage main bearing that obtains lubricant oil can not sufficient lubrication, cause the physical life of main bearing to shorten; Changing main bearing needs a lot of time equally, and therefore causes stopping production.
Summary of the invention
The present invention be directed to the deficiency of prior art, take two-way to import the mode of lubricant oil simultaneously, designed a kind of oil leab that is applicable to the high-speed high-power Reciprocting piston compressor.
The present invention seeks to realize like this:
Be applicable to the oil leab of high-speed high-power Reciprocting piston compressor; Comprise oil pump and transmission oil circuit; It is characterized in that: lubricant oil is through after the oil pump; Arrive main oil gallery and be divided into two-way; One the tunnel through fuselage main bearing oil duct; Flow through the successively oil duct of crankshaft-and-connecting-rod bottom-end bearing flows back to the fuselage oil sump by connecting rod bottom-end bearing; Another road flows on crosshead and the small end bearing through the side oil duct, and by back oil road lubricant oil is returned the fuselage oil sump.
The invention has the beneficial effects as follows: the present invention has changed the prior art forward or has oppositely transmitted the mode of lubricant oil step by step; To be divided into two-way from the lubricant oil that main oil gallery comes; Lubricant oil is being transferred to the fuselage main bearing; Bent axle; In the time of connecting rod bottom-end bearing; Also be transferred to small end bearing; Such mode is because transmission course has reduced one-level; Therefore the influence that the decline of pressure can be not too many is lubricated; It is well lubricated that four parts are all obtained; And then the working life of prolongation parts; Simultaneously; Obtaining under the situation of sufficient lubrication; The fuselage main bearing; Bent axle; Connecting rod bottom-end bearing; The temperature of the several rotatable parts of small end bearing also can descend, and therefore can improve the functional reliability of complete machine.

Fig. 2 is a lubricating oil path flow chart of the present invention
Mark among the figure: 1 main bearing seat and seat inside crankshaft, 2 compressor crankcase oil sumps, 3 crank pin end pores, 4 connecting rod small end holes, 5 crossheads, body crosshead slideway in 6,7 main oil gallerys, 8 lubricating oil purifiers, 9 oil pump, 10 compressor oil cooling machines.
Embodiment
Structure of the present invention and connection: the present invention includes oil pump and transmission oil circuit, on main oil gallery, be connected with the side oil duct, the side oil duct flows to crosshead earlier, arrives connecting rod small end through crosshead again; Main oil gallery directly communicates with each main bearing oilhole, to big end bearing, returns oil sump through the oilhole on the bent axle then, and the lubricant oil that lubricates small end bearing also returns the fuselage oil sump by main oil gallery.
The fuselage internal oil channel is made up of main oil gallery, main bearing seat oil duct, side oil duct.Main oil gallery is that seamless steel pipe casts from fuselage oil sump bottom, and the main bearing seat oil duct is a seamless steel pipe, casts from fuselage main bearing seat below, and an end and main oil gallery are connected, and the other end outlet is positioned on the main bearing seat.The side oil duct is a seamless steel pipe, casts from fuselage oil sump bottom, and an end and main oil gallery are connected, and the other end outlet is positioned on the fuselage side walls.
In the compressor operating process, oil pump through main oil gallery, divides 2 the tunnel to be lubricated in machine oil.One the tunnel to carry out oil transportation through main oil gallery, main bearing seat oil duct, crankshaft main journal, crank pin end pore lubricated, mainly main bearing and crankshaft main journal, connnecting rod big end watt and these 2 pairs of friction pairs of crank-shaft link neck is lubricated; Another road is through main oil gallery, side oil duct, and oil transportation to crosshead slideway arrives the connecting rod small end hole after crosshead slideway, crosshead, mainly crosshead and these two pairs of friction pairs of crosshead slideway, lining of connecting rod small end and crosshead pin are lubricated.
