Electric cleaner self-lubricating slip column
Technical field
The utility model relates to a kind of electric cleaner, is specifically related to a kind of electric cleaner self-lubricating slip column.
Background technology
Electric cleaner is widely used in iron and steel, nonferrous metallurgy, building materials, power industry, chemical industry and other industrial circles and even civil area.Because the electric cleaner expanded by heating can produce relatively between basic framework and the body and slide.Prior art all is to form sliding friction pair at the traditional oil of column surfaces coated one deck, grease lubrication, stainless steel and polytetrafluoroethylene (PTFE), and in fact traditional oil, grease lubrication can not satisfy its abominable work condition environment.At present, form the self-lubricating bearing of sliding friction pair by a kind of stainless steel and polytetrafluoroethylene (PTFE), but, therefore will avoid it to run into naked light because polytetrafluoroethylene (PTFE) produces the pair thing fluorophosgene and the perfluoroisobutylene of severe toxicity when Pintsch process.And polytetrafluoroethylene (PTFE) can use when being no more than 260 ℃ for a long time, reduce greatly but surpass 260 ℃ of its superior functions, and when surpassing 385 ℃, the polytetrafluoroethylene (PTFE) molecule will destroy, and influences the normal operation of equipment.But the serviceability temperature of electric cleaner or other equipment is mostly all more than 350 ℃, and naked light very likely appears in operating mode.
Summary of the invention
The utility model technical problem to be solved provides a kind of electric cleaner self-lubricating slip column; Can use at 300-500 ℃ long-term; And coefficient of friction is littler under condition media such as high speed, high pressure, high temperature, high load capacity and Korrosionsmedium, and effect is better.
For solving the problems of the technologies described above; The technical scheme that the utility model electric cleaner self-lubricating slip column is adopted is: it comprises slip column and lower slider column; The contact-making surface of last slip column is a corrosion resistant plate; The contact-making surface of lower slider column is the self-lubricating diaphragm, and this self-lubricating diaphragm is for applying the copper alloy plate of one deck fluorographite kollag.
Slip column in the technique scheme mainly leans on the sliding friction pair of being made up of corrosion resistant plate and self-lubricating diaphragm to work; And the self-lubricating diaphragm adopts copper alloy and fluorographite kollag to combine; Has excellent lubrication property; Solve prior art and can not be higher than the long-term problem of using under 260 ℃ of situation, better, wear-resisting, withstand voltage, high temperature resistant, the anticorrosion of effect under high speed, high pressure, high temperature, high load capacity, corrosivity condition; And metal and other materials are not produced corrosiveness, can use at 300-500 ℃ long-term.

The specific embodiment
The utility model electric cleaner self-lubricating slip column is divided into two kinds on two-way slip column and unidirectional slip column.
Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4; The electric cleaner self-lubricating slip column of this embodiment is two-way slip column; It comprises slip column 1 and lower slider column 2; The contact-making surface of last slip column 1 is a corrosion resistant plate 3, and the contact-making surface of lower slider column 2 is a self-lubricating diaphragm 4, and self-lubricating diaphragm 4 is for applying the copper alloy plate of one deck fluorographite kollag.
Referring to Fig. 5, Fig. 6 and Fig. 7; The electric cleaner self-lubricating slip column of this embodiment is unidirectional slip column; It comprises slip column 1 and lower slider column 2; The contact-making surface of last slip column 1 is a corrosion resistant plate 3, and the contact-making surface of lower slider column 2 is a self-lubricating diaphragm 4, and self-lubricating diaphragm 4 is for applying the copper alloy plate of one deck fluorographite kollag.
Two-way, the unidirectional faying face that slides up and down column is the friction pair that corrosion resistant plate and self-lubricating diaphragm are formed, and need not to be coated with lubricant, and guarantees that the coefficient of friction between the two sides is not more than 0.15.The bolt, nut that connects slip column usefulness during only as installation and transportation, equipment are installed after test run finishes, and must lay down.
Last slip column 1 in above-mentioned two kinds of embodiments and lower slider column 2 are the steel bracket of channel-section steel and steel plate composition, and last slip column 1 combines with lower slider column 2, are exactly the sliding friction pair of being made up of corrosion resistant plate 3 and self-lubricating diaphragm 4.To go up slip column 1 and 2 combinations of lower slider column; When expanded by heating appears in equipment; The slip column will be brought into play its superiority; Owing to will take away after the installation test runs such as bolt of upper and lower slip column, above slip column 1 and lower slider column 2 will produce slip between the self-lubricating diaphragm in the middle of them behind the expanded by heating.Wherein two-way slip column can slide to X, Y both direction, and individual event slip column can only slide to X or to direction of Y.Can avoid the relative slip that body and basic platform be heated and cause equipment normally to move.
Because fluorographite is important nonmetallic materials, has excellent lubrication property.Its effect under high speed, high pressure, high temperature, high load capacity, corrosivity condition is better, and metal and other materials is not produced corrosiveness.Therefore, fluorographite be known as the electricity and the heat insulation body.Electric cleaner is used at 300-500 ℃ long-term, and coefficient of friction is littler under condition media such as high speed, high pressure, high temperature, high load capacity and Korrosionsmedium, effect is better.
Fluorographite and copper alloy plate adopt the mode of copper matrix inlaid to combine, in use can self-lubricating, need not lubricating oil.
