Abstract
The utility model provides a novel balance type reciprocating mechanism for a booster pump, comprising a rigid combination type crosshead which is composed of crossheads (4, 14) and a connection frame (13), a connecting rod (5), bearing shells (6, 8), a crosshead pin (7), an eccentric block (9), a rotating shaft (10), a machine body (12), etc., wherein, the rigid combination type crosshead has a stable circular arc guide, and the connecting rod (5) is respectively connected with the crosshead pin (7) and the eccentric block (9) through the bearing shell (6, 8). The utility model with simple structure and reasonable configuration improves the stress and the lubrication circumstances of the bearing shell, and extends service life.
Description
The utility model belongs to a kind of mechanism that suction booster is used, and particularly is the novel balanced type reciprocator that a kind of suction booster is used.
Proposing mechanism similar with this patent is frame type eccentric shoe reciprocator, as Fig. 1, it is made up of cover 6 ', framework 7 ', slide block 8 ', eccentric mass 9 ', running shaft 10 ', crosshead 11 ', body 12 ', when running shaft 10 ' rotation, drive eccentric mass 9 ' rotation, cause slide block 8 ' in framework 7 ', to slide, thereby framework drive crosshead 11 ' to-and-fro motion, drives plunger 5 ' to-and-fro motion again.This mechanism is when high-speed motion, and slide block 8 ', framework 7 ' wear and tear bigger, and be lubricated relatively poor with stressing conditions.With this patent mechanism the essence difference is arranged.
The purpose of this utility model is to provide the suction booster novel balanced type reciprocator after a kind of the improvement, and it is when high speed operation, and stressed, the lubrication circumstances of bearing shell all improve, and increase working life greatly.
Fig. 1. existing suction booster frame type eccentric shoe reciprocator.
Fig. 2. suction booster novel balanced type reciprocator.
Fig. 3. the general stressed sketch of reciprocator's bearing shell.
Fig. 4. the stressed sketch of novel balanced type reciprocator bearing shell.
The utility model is realized by following technology contents: the utility model balance reciprocating mechanism for booster pump as shown in Figure 2, comprises link (13) and crosshead (4,14), consist of a box-like crosshead of rigid group, and connecting rod (5), bearing shell (6,8), crosshead pin (7), eccentric block (9), rotating shaft (10), cover (11), the compositions such as body (12). When rotating shaft (10) High Rotation Speed, drive eccentric block (9) and in bearing shell (8), rotate, drive the box-like crosshead of rigid group (4,14) and move back and forth by connecting rod (5), bearing shell (6), crosshead pin (7), reach the purpose of expection.
Adopted connecting rod (5), and since link press span (13) directly connect stablize the garden arc guide to and the crosshead (4 that is symmetric arrangement, 14), form the box-like cross head design of rigid group, improved running shaft (10) eccentric mass (9) and bearing shell (8), and crosshead pin (7) and the stressed and lubrication state of bearing shell (6).
The utility model has the advantages that: realized above-mentioned purpose, fundamentally solved general suction booster and caused the phenomenon of often burning bearing shell because of insufficient lubrication.
Former general reciprocator takes pump inlet pressure height by force owing to increase, and makes main shaft be subjected to force direction constant, causes the stressed side of bearing shell too, and two bearing shell B face (see figure 3)s are pressurized all the time, and it is insufficient that the surface forms oil film, causes two bearing shell cisco unity malfunctions, often burns.Frame type eccentric shoe reciprocator, the slide block insufficient lubrication is also fragile.The utility model is because of having adopted novel balanced type reciprocator, its mechanism passes through bearing shell (6 by same connecting rod (5), 8) link with crosshead pin (7) and eccentric mass (9) respectively, therefore can drive two opposed type crossheads moves reciprocatingly, like this, no matter how high the suction booster inlet pressure is, because of pump advances, outlet pressure is different, main shaft is subjected to force direction, size is alternate all the time, improved the force-bearing situation of two bearing shells, make two bearing shell A faces and the stressed size of B face (see figure 4), direction is alternate also, it is abundant that the surface forms oil film, guaranteed the proper functioning needs of two bearing shells, fundamentally solved because of the high difficult problem of often burning bearing shell of suction booster inlet pressure, the operating life that has prolonged suction booster.
Below in conjunction with embodiment the utility model is further described; As shown in Figure 2: crosshead (4,14) casting the back machining with spheroidal graphite cast iron forms, reprocessing after heat treatment after connecting rod (5) forges with No. 45, bearing shell (6,8) with lead based alloy or use cupro lead, cross closes pin 20Cr carburizing and quenching, surface hardness reaches HRC55～60 degree, eccentric mass (9) and running shaft are with 40Cr or No. 45 steel, eccentric size decide by the stroke of pump, and cover (11), body (12) cylinder iron HT200 or HT250 are cast and formed, crosshead (4,14) cooperates with this employing of machine H8/f9.
