Abstract
The utility model relates to a wearproof anti-vibrating thermocouple resistance. The outer layer of the temperature sensing element of the existing thermocouple is additionally sheathed with a wearproof casing tube made of wearproof material, and the outer layer of the wearproof casing tube is sheathed with an anti-vibrating casing tube. The utility model has the advantages of material saving, simple manufacture, and convenient installation; the wearproof anti-vibrating thermocouple resistance can prolong service life; the wearproof anti-vibrating thermocouple resistance is suitable for the various occasions where have serious vibration and are easy to wear.
Description
The utility model relates to a kind of thermal meter, specifically, is a kind of thermoelectric corner thermal resistance with wear-resisting anti-vibration functions that is used to measure high temperature.
In the coal dust and smoke dust system of coal fired power generation machine, temperature is the outlet temperature of important thermal technology's monitoring parameter, particularly coal pulverizer, is to be related to the signal of interest that can whole generating machine system normally move.Normally in the exit of coal pulverizer, two thermoelectric corner thermal resistances are installed, measure the temperature at this place exactly.But; because this place's temperature height, the coal dust flow velocity is big, serious vibration; so; damage to thermoelectric corner is very serious, and this not only increases production cost, and will often shut down and change thermoelectric corner; influence the normal operation of generator system; particularly damage and cause measurement data inaccurate, wrong signal is provided because of thermoelectric corner, then bigger to the harm of whole generator systems.
The purpose of this utility model is to design a kind of thermoelectric corner wear-resisting, the vibrationproof performance that has, and overcomes the defective that existing thermoelectric corner is damaged easily.
The utility model is that the skin at temperature-sensing element adds cover one deck wear-resistant sleeve, is worn to prevent temperature-sensing element; Skin at wear-resistant sleeve adds cover one deck vibrationproof sleeve pipe, prevents that wear-resistant sleeve from damaging because of vibration.Like this, just reached and prolonged the thermoelectric corner purpose in serviceable life.
The utility model is through on probation, than having prolonged 30 times the serviceable life that has thermoelectric corner now.Thereby reduced consumption, reduced and shut down the time of changing thermoelectric corner.
During making, make wear-resistant sleeve (4) with high-abrasive materials such as aluminium oxide, add the skin that is enclosed within temperature-sensing element (5), make vibrationproof sleeve pipe (3) with stainless steel again and add the skin that is enclosed within wear-resistant sleeve (4), make vibrationproof sleeve pipe (3) slightly be shorter than wear-resistant sleeve (4), make the high speed pulverized coal flow directly be flushed in the end that vibrationproof sleeve pipe (4) exposes.Because high-abrasive materials such as aluminium oxide at high temperature still have wear-resisting functions, can protect temperature-sensing element (5) not wear and tear because of washed away by the high speed pulverized coal flow.Because the utility model only exposes in an end part easy to wear, remainder all is with the vibrationproof sleeve pipe made from stainless steel (3), so under the ring mirror of serious vibration, the utility model is not damaged because of shaking.
Accompanying drawing is a synoptic diagram of the present utility model.
Among the figure: 1, terminal box, 2, hold-down nut, 3, the vibrationproof sleeve pipe, 4, wear-resistant sleeve, 5, temperature-sensing element, 6, the thermometric contact.
Below, in conjunction with the accompanying drawings, a non-limiting examples is illustrated.
Terminal box of the present utility model (1), hold-down nut (2), temperature-sensing element (4), thermometric contact (6) all corresponding part with former thermoelectric corner are identical.Wear-resistant sleeve of the present utility model (4) is to become hemispheric hollow sleeve with the end that high-abrasive materials such as aluminium oxide are made, and at hollow space thermometric contact (6) and temperature-sensing element (5) is housed; The hollow tube that vibrationproof sleeve pipe of the present utility model (3) is made with stainless steel than short 150 millimeters of wear-resistant sleeve (4), adds the skin that is enclosed within wear-resistant sleeve (4).Use, installation method all are same as former thermoelectric corner.
It is easy, easy for installation that the utility model materials are saved, made, and is fit to strong, the easy to wear environment measurement high temperature of various vibrations.
Claims (1)
1, the thermoelectric corner of wear-resisting vibrationproof thermal resistance is made up of terminal box (1), hold-down nut (2), temperature-sensing element (5), thermometric contact (6), it is characterized in that:
(1) periphery of temperature-sensing element (5) adds and is with the wear-resistant sleeve made from high-abrasive material (4);
(2) add in the periphery of wear-resistant sleeve (4) and be with vibrationproof sleeve pipe (3).
