Abstract
A piston apparatus for reciprocating pump, is characterized in that: comprise ceramic cylinder rod and piston friction seal ring, described piston friction seal ring is enclosed within ceramic cylinder rod outside, and piston friction seal ring is used high temperature resistant self-lubricating material to be made.The utility model is by improving structure and the material of piston, improved the mechanical property of piston, simplified the reducing gear in former reciprocating pump, the running speed that also makes piston is brought up to present 2000 revs/min by former 500 revs/min, has greatly improved the working efficiency of reciprocating pump.
Description
Technical field
The utility model relates to a kind of piston apparatus, relates in particular to a kind of piston apparatus of reciprocating pump.
Background technique
Piston is one of critical component of reciprocating pump, and piston mobile produces two strokes, in first stroke, by suction valve, sucks and needs the fluid carried, in second stroke by expulsion valve by described fluid expulsion, reach the object of Fluid Circulation.
Present stage, the piston rod of piston was all cast iron manufacture substantially, there is no drag seal or adopted asbestos as drag seal.Because the radiating effect of cast iron is poor, add its physical property and determined that piston can not run up for a long time in maintenance, otherwise must be stuck; Asbestos resistance to high temperature is poor, and thicker, and general asbestos seal ring thickness, all in 24mm left and right, has greatly reduced the inner space of cylinder head, has reduced the output flow of reciprocating pump, and piston pump performance is had a greatly reduced quality.
Summary of the invention
The purpose of this utility model is defect and the deficiency that overcomes prior art, and a kind of simple in structure, reliable and stable piston apparatus is provided.
For realizing above object, technical solution of the present utility model is: a kind of piston apparatus of reciprocating pump, it is characterized in that: comprise ceramic cylinder rod and piston friction seal ring, described piston friction seal ring is enclosed within ceramic cylinder rod outside, and piston friction seal ring is used high temperature resistant self-lubricating material to be made.
The making material of described ceramic cylinder rod is 99 porcelain, and the making material of described piston friction seal ring is teflon.
Described piston friction seal ring is arranged in piston fixed cover.
Compared with prior art, the beneficial effects of the utility model are:
1, the utility model is by improving structure and the material of piston, improved the mechanical property of piston, simplified the reducing gear in former reciprocating pump, the running speed that also makes piston is brought up to present 2000 revs/min by former 500 revs/min, has greatly improved the working efficiency of reciprocating pump.
2, the utility model is used 99 porcelain to make material as piston rod, 99 porcelain are as the new material of high-end porcelain, there is the characteristics such as high temperature resistant, corrosion-resistant, wear-resisting, hardness is high, and the degree of finish of ceramic surface energy can reach 0.05, fully be reduced in the frictional strength in high speed to-and-fro motion, reduce heating value; Sealing seal ring adopts teflon to make, can guarantee that Sealing still can keep long motive sealing characteristic in the situation system of high-speed and high-temperature kinetic friction, and the self-lubricating property characteristic of teflon can guarantee that piston rod there will not be stuck phenomenon in high speed to-and-fro motion.
3, the utility model adopts piston friction seal ring is arranged in piston fixed cover, has so not only improved the sealability of piston, and has made the easier for installation of piston.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the sectional drawing of Fig. 1.
In figure: ceramic cylinder rod 1, piston friction seal ring 2, piston fixed cover 3.
Embodiment
Below in conjunction with accompanying drawing explanation and embodiment, the utility model is described in further detail.
Referring to Fig. 1-Fig. 2, a kind of piston apparatus of reciprocating pump, comprise ceramic cylinder rod 1 and piston friction seal ring 2, described piston friction seal ring 2 is enclosed within ceramic cylinder rod 1 outside, described piston friction seal ring 2 is arranged in piston fixed cover 3, the making material of described ceramic cylinder rod 1 is 99 porcelain, and the making material of described piston friction seal ring 2 is teflon.
The utility model is made ceramic cylinder rod 1 for convenience of installation hollow when making, and only ceramic cylinder rod 1 need be enclosed within on the center-pole of reciprocating pump when mounted, and piston fixed cover 3 is fixed in the piston mounting hole on cylinder head.When reciprocating pump is worked, power engine is by the bent axle of belt transmission driven plunger pump, the gearing of bent axle by connecting rod and intermediate bar drives ceramic cylinder rod 1 to move reciprocatingly in piston friction seal ring 2, and the to-and-fro motion by ceramic cylinder rod 1 causes pump head internal pressure to change to guarantee the lasting turnover of liquid.
