Piezoelectric Quartz Dynamic Weighing Sensor CET8312
Tlhaloso e Khutšoanyane:
CET8312 Piezoelectric Quartz Dynamic Weighing Sensor e na le litšobotsi tsa mefuta e mengata ea ho lekanya, botsitso bo botle ba nako e telele, ho pheta-pheta hantle, ho nepahala ha tekanyo e phahameng le maqhubu a phahameng a ho arabela, kahoo e loketse ka ho khetheha bakeng sa ho lemoha boima bo matla. Ke sensor e thata, e matla ea ho bekha e thehiloeng holim'a molao-motheo oa piezoelectric le sebopeho se nang le tokelo ea molao. E entsoe ka letlapa la kristale ea quartz ea piezoelectric, poleiti ea electrode le sesebelisoa se khethehileng sa beam. E arotsoe ka 1-mithara, 1.5-mithara, 1.75-limithara, 2-limithara boholo litlhaloso, e ka kopantswe ka mefuta e fapaneng ya litekanyo tsa sephethephethe tseleng, ka ikamahanya le maemo a boima bo boima litlhoko tsa holim'a tsela.

Mokhoa oa ho kenya
Kakaretso ea Sebopeho
E le ho netefatsa phello ea tlhahlobo ea ho kenngoa hohle ha sensor, khetho ea sebaka e lokela ho ba thata. Ho etsoa tlhahiso ea hore sebaka se thata sa samente se khethoe e le motheo oa ho kenya sensor, 'me tsela e bonolo e kang asphalt e lokela ho fetoloa. Ho seng joalo, ho nepahala ha tekanyo kapa bophelo ba tšebeletso ea sensor bo ka ameha.
Mount Bracket
Ka mor'a hore sebaka se behoe, sekontiri se nang le likoti tse fanoeng ka li-sensor se lokela ho ts'oaroa ho sensor e nang le tepi e telele ea terata, ebe ho sebelisoa lehong le lenyenyane la kgutlotharo ho kenya lekhalo pakeng tsa lebanta le tie-up le bracket e ntseng e phahama, e le hore e ka tiisoa. Haeba basebetsi ba lekane, mohato oa (2) le (3) o ka etsoa ka nako e le 'ngoe. Joalokaha ho bontšitsoe ka holimo.
Pavement Grooving
Sebelisa rula kapa sesebelisoa se seng ho tseba hore na sensor e matla ea boima e eme hokae. Mochine oa ho itšeha o sebelisetsoa ho bula li-grooves tse nang le mahlakore a mabeli tseleng.
Haeba li-grooves li sa lekane 'me li na le likhahla tse nyenyane moeling oa li-grooves, bophara ba li-grooves ke 20 mm ho feta ea sensor, botebo ba li-grooves ke 20 mm ho feta ea sensor, le 50 mm e telele ho feta ea sensor. Li-cable groove li bophara ba 10 mm, botebo ba 50 mm;
Haeba li-grooves li entsoe ka hloko 'me lipheletsong tsa li-grooves li boreleli, bophara ba li-grooves ke 5-10mm ho feta ea li-sensor, botebo ba li-grooves ke 5-10mm ho feta li-sensor,' me bolelele ba li-grooves ke 20-50mm ho feta li-sensor. Li-cable groove li bophara ba 10 mm, botebo ba 50 mm.
Botlaaseng bo tla fokotsoa, silt le metsi ka har'a li-grooves li tla hlajoa li hloekile ka pompo ea moea (ho omisoa ka ho feletseng ho tlatsa grout), 'me karolo e ka holimo ea mahlakoreng ka bobeli a li-grooves e tla kenngoa ka tepi.
Nako ea Pele ea Grouting
Bula grout ea ho kenya, ho ea ka karolo e behiloeng ho lokisa motsoako o tsoakiloeng, ka potlako ho kopanya grout le lisebelisoa, ebe o tšela ka tsela e lekanang ho latela tataiso ea bolelele ba groove, ho tlatsoa ha pele ka groove ho lokela ho ba ka tlase ho 1/3 ea botebo ba groove.
Sensor Placement
Ka bonolo beha sensor ka bracket e ntseng e hola ka har'a slot e tletseng grout, lokisa bracket e ntseng e phahama 'me u etse hore fulcrum e' ngoe le e 'ngoe e ame bokaholimo ba slot,' me u netefatse hore sensor e bohareng ba slot. Ha li-sensor tse peli kapa ho feta li kenngoa ka har'a slot e le 'ngoe, tlhokomelo e khethehileng e lokela ho lefshoa karolong ea khokahanyo.
Sebaka se ka holimo sa li-sensor tse peli se tlameha ho ba boemong bo lekanang, 'me motsoako o tla ba o monyenyane ka hohle kamoo ho ka khonehang, ho seng joalo phoso ea tekanyo e tla bakoa. Boloka nako e ngata kamoo ho ka khonehang mohatong oa (4) le (5), kapa grout e tla phekola (lihora tse 1-2 tsa nako e tloaelehileng ea ho folisa ea sekhomaretsi sa rona).
Ho tlosoa ha Mounting Bracket le Second Grouting
Ka mor'a hore grout e folisoe, sheba phello ea pele ea ho kenya sensor, 'me u e fetole ka nako ha ho hlokahala. Ntho e 'ngoe le e' ngoe e se e loketse, ebe u tlosa bracket, u tsoele pele ka grouting ea bobeli. Ente ena e lekanyelitsoe ho bophahamo ba holim'a sensor.
Nako ea Boraro ea Grouting
Nakong ea ho folisa, ela hloko ho eketsa palo ea grout ka nako leha e le efe, e le hore boemo bo akaretsang ba grout ka mor'a ho tlatsa bo phahame hanyenyane ho feta tsela.
Ho Sila ka Bokaholimo
Ka mor'a hore li-grout tsohle tsa ho kenya li fihlele matla a ho folisa, khaola theipi, 'me u sila bokaholimo ba groove le holim'a tsela, etsa tlhahlobo ea preloading ka koloi e tloaelehileng kapa likoloi tse ling ho hlahloba hore na ho kenngoa ha sensor ho nepahetse.
Haeba tlhahlobo ea preloading e tloaelehile, ho kenya ke
