Problems solved by technology
[0005] The sliding column in the above technical solution mainly works by the sliding friction pair composed of stainless steel plate and self-lubricating diaphragm, and the self-lubricating diaphragm is made of copper alloy and fluorinated graphite solid lubricant, which has excellent lubricity , which solves the problem that the existing technology cannot be used for a long time at a temperature higher than 260°C, and has better effects under high-speed, high-pressure, high-temperature, high-load, and corrosive conditions. It is wear-resistant, pressure-resistant, high-temperature resistant, and corrosion-resistant, and Does not cause corrosion to metals and other materials, and can be used for a long time at 300-500°C

Embodiment Construction
[0013] The self-lubricating sliding column of the electrostatic precipitator of the present invention is divided into two types: a two-way sliding column and a one-way sliding column.
[0014] see figure 1 , figure 2 , image 3 with Figure 4 , the self-lubricating sliding column of the electrostatic precipitator of the present embodiment is a two-way sliding column, which includes an upper sliding column 1 and a lower sliding column 2, the contact surface of the upper sliding column 1 is a stainless steel plate 3, and the contact surface of the lower sliding column 2 is a self-lubricating column. The lubricating diaphragm 4, the self-lubricating diaphragm 4 is a copper alloy plate coated with a layer of fluorinated graphite solid lubricant.
[0015] see Figure 5 , Image 6 with Figure 7 , the self-lubricating sliding column of the electrostatic precipitator of the present embodiment is a one-way sliding column, which includes an upper sliding column 1 and a lower sli...

The invention discloses a self-lubricating sliding stand column of an electric precipitator, which comprises an upper sliding stand column and a lower sliding stand column. The contact surface of the upper sliding stand column is a stainless plate, the contact surface of the lower sliding column is a self-lubricating membrane which is a copper alloy plate coated with a layer of graphite fluoride solid lubricant. The self-lubricating sliding stand column of the electric precipitator solves the problem of short-term use at the temperature of 260 DEG C in the prior art, has good lubricity, has better effects under the conditions of high speed, high pressure, high temperature, high load and corrosiveness, resists abrasion, pressure, high temperature and corrosion, can not corrode metal and other materials, and can be used for a long time at the temperature of 300 DEG C-500 DEG C.
Description
technical field [0001] The invention relates to an electric precipitator, in particular to a self-lubricating sliding column of the electric precipitator. Background technique [0002] Electrostatic precipitators are widely used in iron and steel, non-ferrous metallurgy, building materials, electric power industry, chemical industry and other industrial fields and even civil fields. Due to thermal expansion of the electrostatic precipitator, there will be relative sliding between the basic frame and the body. In the existing technology, a layer of traditional oil and grease lubrication, stainless steel and polytetrafluoroethylene is applied to the surface of the column to form a sliding friction pair, but in fact, the traditional oil and grease lubrication can no longer meet its harsh working conditions. At present, there is a self-lubricating bearing with a sliding friction pair composed of stainless steel and polytetrafluoroethylene, but since polytetrafluoroethylene prod...
