Abstract
The utility model relates to a dynamic seal device for a high power high pressure displacement pump lubricating system, which is characterized in that a metal frame is fixedly installed in a displacement pump crank installing hole, an oil seal is inserted in the inner hole of the metal frame, the oil seal tightly embraces the top circle of an oil pipe connecting pipe, the metal frame is provided with a self-tightening spring, the oil seal gland tightly presses on the outer end face of the metal frame and is fastened with the displacement pump crank, and a seal ring is inserted on the top circle of the metal frame. The dynamic seal device for a high power high pressure displacement pump lubricating system has the advantages that the oil seal installed in the metal frame tightly extends in the metal frame by the self-tightening spring and pre-tightening force and tightly embraces the oil pipe connecting pipe, and static seal is guaranteed to be reliable, the oil seal has good rebound elasticity, memory property and abrasion resistance, the friction coefficient is less than one fifth of normal oil seal materials, the oil seal can improve the working pressure of lubricating oil over two times, increase the linear speed more than five times, and the service life of a seal element in the same usage condition can be prolonged more than five times.
Description
Technical field
The utility model belongs to the high-pressure plunger pump technical field, particularly relates to a kind of high-power high voltage plunger pump lubrication system dynamic seal apparatus.
Background technique
High-pressure plunger pump is mainly used in the various liquid mediums that industry is cleaned, paint removal, hot-strip de-scaling, oil field are eliminated rust in the metal surface and feed flows such as colliery water filling or injecting are less, pressure is higher and carries.The motive sealing of traditional its driving end lubrication system of high-pressure plunger pump series products is common mechanical seal, this mechanical seal generally is to be applied under the fixing applying working condition of a rotational shell, and the lubricant oil motive sealing of high-pressure plunger pump residing be that axle is static, the operating mode of shell rotation.When lubricant oil passes through in the middle of mechanical seal, owing to limit by the existing machinery sealing configuration, its oil pressure can not too high (less than 1.0bar), generally below 0.5m/s, therefore can't satisfy the operating conditions of lubricant oil motive sealing, so cause plunger pump driving end sealing failure, and then influenced the quality of high-pressure plunger pump.In addition, common axle all can't reach the applying working condition requirement of high-pressure plunger pump, all employings at present with its linear velocity of outside framework oil seal and wear resistance.
Summary of the invention
The utility model provides a kind of high-power high voltage plunger pump lubrication system dynamic seal apparatus that improves plunger pump lubricant oil working pressure and linear velocity, oil sealing wear resistance and can increase the service life for solving the technical problem that exists in the known technology.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
The utility model can also adopt following technological scheme: high-power high voltage plunger pump lubrication system dynamic seal apparatus, the oil pipe that comprises the plunger pump bent axle and be installed on the crankcase is taken over, it is characterized in that: the plunger pump crankshaft installed is fixed with metal frame in the hole, the hole is embedded with oil sealing in the metal frame, oil sealing is held tightly at oil pipe and is taken on the cylindrical, on metal frame, be provided with the self-tightening spring of one end and oil sealing plug-in mounting, oil sealing cover is pressed on metal frame exterior edge face and fastening with plunger pump bent axle one end face, is embedded with seal ring on the metal frame cylindrical.
The cross section of described oil sealing is the lip structure.
Described oil sealing is that nonmetal low fricting polymerization material is made.
Described seal ring is an O-ring seals.
Advantage and the good effect that the utlity model has are: because the utility model adopts said structure, be installed in oil sealing in the metal frame by self-tightening spring and pretightening force tensioner in metal frame and hold oil pipe tightly and take over, guarantee that its static seal is reliable; This outer oil seal adopts nonmetal low fricting polymerization material to make, make it have preferable rebound elasticity, Memorability and wear resistance, its friction factor only is that the conventional oil closure material is below 1/5th, the lubricant oil working pressure is improved more than the twice, linear velocity improves more than five times, prolongs more than five times in the life-span of equal service condition lower seal.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, O-ring seals; 2, metal frame; 3, self-tightening spring; 4, oil sealing; 5, plunger pump bent axle; 6, oil pipe is taken over; 7, oil sealing cover.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, high-power high voltage plunger pump lubrication system dynamic seal apparatus, the oil pipe that comprises plunger pump bent axle 5 and be installed on the crankcase takes over 6, is fixed with metal frame 2 in plunger pump bent axle 5 mounting holes, and this metal frame mainly is to support for oil sealing 4 provides a skeleton.The hole is embedded with oil sealing 4 in the metal frame, and oil sealing 4 is held tightly on the cylindrical of oil pipe adapter 6, makes it have the rotary seal function.Described oil sealing 4 is made for nonmetal low fricting polymerization material, and the oil sealing Cross section Design is the lip structure, is provided with the self-tightening spring 3 of one end and oil sealing lip plug-in mounting on metal frame.Oil sealing cover 7 is pressed on metal frame exterior edge face and fastening by screw and plunger pump bent axle 5 one end faces, on the metal frame cylindrical, be embedded with O-ring seals 1, this O-ring seals plays the effect of sealing metal skeleton and plunger pump bent axle 5 mounting holes, also can be metal frame simultaneously and rotates the frictional force that provides certain with the plunger pump bent axle.
Working principle of the present utility model is: when 5 rotations of plunger pump bent axle, rely on the frictional force (between metal frame 2 and the mounting hole end face) of oil sealing cover 7 impacting forces generation and the frictional force of O-ring seals 1 and the generation of seal mounting hole cylndrical surface, oil sealing is rotated with the plunger pump bent axle, and O-ring seals has guaranteed reliable static seal between metal frame and plunger pump bent axle 5 mounting hole cylndrical surface.The oil sealing that is installed in hole in the metal frame is by pretightening force tensioner hole and guarantee that its static seal is reliable in metal frame.During work, oil sealing 4 endoporus of rotation and static oil pipe are taken over 6 and are in the relative movement state, and the oil sealing lip that plays a crucial role relies on self-tightening spring 3 to hold oil pipe tightly and takes over 6 cylindrical, guarantees that motive sealing is reliable.Oil sealing adopts nonmetal low fricting polymerization material to make, have excellent rebound elasticity, Memorability and wear resistance, friction factor only is below 1/5th of conventional oil closure material, the lubricant oil working pressure can improve more than the twice, linear velocity improves more than five times, and the similarity condition lower seal life-span prolongs more than five times.
