Conas deireadh te teirmeachúpla a ghlanadh nuair a bhíonn salachar nó eisíontais ar dhromchla an réada á thomhas?

Nuair a bhíonn salachar nó eisíontais ar dhromchla an réada á thomhas, teastaíonn an modh cuí a roghnú de réir nádúr na salachar nó na n -eisíontas agus cineál agus struchtúr an teirmeachúpla ., is iad seo a leanas roinnt modhanna glantacháin coitianta: is mó a bhíonn na modhanna glantacháin seo a leanas.
Modh glantacháin fhisiciúil
Wipe: For general dirt such as dust and oil attached to the surface, the hot end of the thermocouple can be gently wiped with a soft cloth or paper towel. If the dirt is stubborn, a small amount of anhydrous ethanol or acetone or other organic solvents can be used to wipe it, but be careful to avoid these solvents from contacting the sensitive parts of the thermocouple to avoid Mar shampla, nuair a bhíonn teocht réada sa tsaotharlann á thomhas, má dhéantar deannach nó méid beag ola a thomhas, má dhéantar é a dhathú le deannach nó le méid beag ola, is iondúil go n -éireoidh sé le liathróid chadáis atá tumtha in eatánól an salachar . a bhaint go héifeachtach
Scrúbáil: Nuair a bhíonn an salachar crua, mar shampla scála ocsaíde nó ábhair triomaithe ar an dromchla miotail, is féidir scuab bog nó scuab copair a úsáid chun é a scrobarnach go réidh . ach bí cúramach gan scrobarnach a dhéanamh ró -dheacair chun dochar a dhéanamh do leictreoid nó muinchille cosanta i dtáirgeadh te an teolaí de théama an teirmeach {{}}} {}} {}} {} {}} {} {1} {} {} {} {} {} a: D'fhéadfadh go mbeadh scála ocsaíd éigin ag na hábhair sa Foirnéis Teasa ceangailte leis {. Is féidir na scálaí ocsaíde seo a bhaint trí scuab bog a scuabadh go cúramach .
Sandblasting: I gcás roinnt salachar atá deacair a bhaint trí shruthlú nó scuabadh, mar shampla salachar crua atá sintéirithe ar dhromchla an teirmeachúpla, is féidir gaineamh a úsáid le haghaidh glantacháin . Sandblasting Is é an t-úsáid a bhaintear as an dínn a bhaineann le gaineamh a bhaint, chun an gaineamh a bhaint, chun deireadh a chur le cáithníní gaineamh, gaineamh a bhaint, chun an gaineamh a bhaint, an gaineamh gaineamh a bhaint, an gaineamh a bhaint, an gaineamh a bhaint de na gaineamh i ngaineamh an ghaineamh a bhaint, Éilíonn sé trealamh gairmiúil, agus caithfear brú agus am an ghainimh a rialú chun damáiste don teirmeachúpla {.
Modh glantacháin cheimiceach
Picling: Más ocsaíd mhiotail nó carbónáit an salachar ar an taobh te den teirmeachúpla, is féidir é a ghlanadh trí phiciliú . Roghnaigh tuaslagán aigéad oiriúnach de réir chomhdhéanamh na salachar, amhail aigéad hidreaclórach, aigéad nítreach, sulfuric aigéad, srl. with the acid and dissolve. For example, for thermocouples that measure the temperature in the heating furnace of a steel plant, the hot end may be attached with dirt such as iron oxide, which can be effectively removed by soaking in dilute hydrochloric acid. However, after pickling, it should be rinsed with clean water in time and dried to prevent acid residue from corroding the ThermoCouple .
Alkali washing: When the dirt is grease, wax or certain acidic substances, an alkaline solution can be used for cleaning. Commonly used alkaline solutions include sodium hydroxide, sodium carbonate, etc. Soak the hot end of the thermocouple in an alkaline solution to remove the dirt through saponification or neutralization reaction. For example, in the food processing industry, if the hot end of the thermocouple that measures the temperature of the heating equipment is stained with grease, soaking and cleaning it with a sodium carbonate solution can achieve a better cleaning effect. Similarly, after alkaline washing, it should be thoroughly rinsed with clean water and dried.
Regardless of the cleaning method used, after cleaning the hot end of the thermocouple, it must be checked and calibrated to ensure that the performance and measurement accuracy of the thermocouple are not affected. If the dirt or impurities on the hot end of the thermocouple are very stubborn and difficult to clean, or if the thermocouple may be damaged during the cleaning process, it is recommended to replace it le teirmeachúpla nua chun cruinneas an tomhais teochta a chinntiú .
