Abstract
Plunger type high-pressure water filling pump lubricating oilses leak-proof device, is related to the design field of leak-proof device.The utility model includes crankcase, sets bent axle, connecting rod, plunger pump crosshead, crosshead slideway respectively in crankcase；Bent axle is connected with connecting rod one end, and the connecting rod other end is connected with plunger pump crosshead, and plunger pump crosshead is arranged in crosshead slideway；The plunger pump crosshead connects intermediate bar, and the outer end of intermediate bar is placed through on the outside of crankcase；Oil sealing box is set between intermediate bar and crankcase, oil sealing is set between oil sealing box and intermediate bar；Oil baffle is set close to one end periphery of plunger pump crosshead in intermediate bar；Oil flow channel is provided between the downside of oil baffle and crosshead slideway；Oil baffle is fixedly connected by jump ring with intermediate bar.The utility model is with low cost, the feature such as simple installation, lubricating oil wastage are small, safety and stability performance height, is used on many high-pressure plunger pumps, and save POL expense uses 99% to effect very well, using contrast after preceding and use.
Description
Technical field
The utility model is related to the design field of leak-proof device.
Background technology
The conventional reciprocating high-pressure plunger pump crankcase bearing shell lubrication of current water filling uses splash system lubrication mode, daily
Lubricating oil must be controlled within zone of reasonableness in crankcase during use, once to will result in bearing shell, cross first-class for oil starvation
Part dry friction high temperature failure, causes equipment breakdown.We have found that the main cause of oil starvation is that leakage is caused by field maintenance,
Crankcase lubricating oil maximum leakage position is the seal member of intermediate bar（Oil sealing）, when plunger pump is through operation in a few years, bent axle
Case internal spider head, the centre-to-centre spacing of intermediate bar are changed, and oil sealing does not just reach original sealing effectiveness, if do not repaired immediately
Replacing and make-up oil can cause crankcase temperature to raise, and cause device damage accident.
Utility model content
The utility model purpose is to reduce labor intensity, reduction oil plant cost there is provided one kind for problem above, it is to avoid
The plunger type high-pressure water filling pump lubricating oilses leak-proof device that equipment breakdown occurs.
The utility model includes crankcase, sets bent axle, connecting rod, plunger pump crosshead, ten respectively in the crankcase
Prefix slideway；The bent axle is connected with connecting rod one end, and the connecting rod other end is connected with plunger pump crosshead, the plunger pump ten
Prefix is arranged in crosshead slideway；The plunger pump crosshead connects intermediate bar, and the outer end of the intermediate bar is placed through bent axle
On the outside of case；Oil sealing box is set between the intermediate bar and crankcase, oil sealing is set between the oil sealing box and intermediate bar；
The intermediate bar sets oil baffle close to one end periphery of plunger pump crosshead；The downside of the oil baffle and crosshead slideway it
Between be provided with oil flow channel；The oil baffle is fixedly connected by jump ring with intermediate bar.
The utility model is studied by being dissected to plunger pump internal structure, and the measuring and calculating of intermediate bar running orbit, utilizes plunger
Pump crosshead and crankcase end clearance, in upper half side, one oil baffle of design of intermediate bar and crosshead connecting portion, it is pacified
Fill external diameter and be less than crosshead slideway, prevent lubricating oil from splashing intermediate bar, in practice, have：1st, it is with low cost, letter is installed
Just, 2, lubricating oil wastage it is small, 3, the feature such as safety and stability performance height, used on many high-pressure plunger pumps, effect very well,
POL expense, which is saved, using contrast after preceding and use uses 99%.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of the utility model oil baffle.
Embodiment
As shown in Figure 1, 2, the utility model includes crankcase 1, sets bent axle 2, connecting rod 3, plunger respectively in crankcase 1
Pump crosshead 4, crosshead slideway 5；Bent axle 2 is connected with the one end of connecting rod 3, and the other end of connecting rod 3 is connected with plunger pump crosshead 4, post
Plug pump crosshead 4 is arranged in crosshead slideway 5；Plunger pump crosshead 4 connects intermediate bar 6, and the outer end of intermediate bar 6 is placed through song
The outside of axle box 1；Oil sealing box 7 is set between intermediate bar 6 and crankcase 1, oil sealing 8 is set between oil sealing box 7 and intermediate bar 6；
Oil baffle 9 is set close to one end periphery of plunger pump crosshead 4 in intermediate bar 6；The downside of oil baffle 9 and crosshead slideway 5 it
Between be provided with oil flow channel 10；Oil baffle 9 is fixedly connected by jump ring 11 with intermediate bar 6.
