General introduction

Dry ice pelletizer is a dry ice machine which makes dry ice pellets of liquid Co2.

1. Vipimo vya jumla ni L1450*W800*H1250mm, uzani wavu ni 580kg
2. Uwezo wa uzalishaji

      Ukubwa wa barafu kavu: Dia.3mm na 16 mm;

    Uzito wa barafu kavu: daraja la chakula   ≥1.50

      Uwezo wa barafu kavu: 50kg kwa saa

• Kiwango cha ubadilishaji cha Co2 na Ice≥40%
• maudhui ya maji ya Co2 ya kioevu ＜50ppm;kioevu Co2 shinikizo la kuingiza≤2.0MPa.

Warning: It is forbidden to start ice machine if there is change on filling or pressure of liquid Co2 store tank.

5、Co2 gas comes out through one pipe with flange easy for recovery if necessary; and air discharge must keep open.

6, Jumla ya nguvu ni 3.7kw.

Hydraulic system

1, Uainishaji wa kiufundi

A. Kiwango cha juu cha shinikizo la mfumo ni 21MPa;

2, Shinikizo la kawaida la kufanya kazi ni chini ya 18MPa;

3, mtiririko wa pampu ni 31L/min;

4, nguvu ya injini: 3.7KW;

5, tanki la mafuta lita 140;

6, ukubwa wa tanki la mafuta ni 80*45*40mm

2、National standard 46#, 56#,68# new anti-wear hydraulic oil (Hydraulic oil should be 17-23 CST on kinematic viscosity and oil pollution should be below grade 12, NAS standard.); fill oil through oil hole to top-limit of oil gauge(around total 350L hydraulic oil required). Clean each 6months and replace oil each 12months.

3, Mtihani wa shinikizo la mfumo

Motor imeunganishwa kwa waya kulingana na njia ya kuunganisha waya ya Δna kuhakikisha mwelekeo sahihi wa saa. Anzisha pampu ya mafuta, rekebisha valve ya kufurika ili kudhibiti shinikizo la mfumo. Thamani ya shinikizo la mfumo itaonyeshwa kwenye kipimo cha shinikizo la upande wa kushoto. Na shinikizo la mfumo huu ni 21 MPa. Pendekezo: ni bora kuchagua shinikizo ndogo ikiwa inakidhi mahitaji ya nguvu ya mashine. Kwa njia hii, matumizi ya nguvu yanaweza kupunguzwa; tumerekebisha shinikizo la mfumo huu vizuri kati ya 18-21 Mpa kabla ya mashine kuondoka kiwandani.

4, Mtihani wa relay ya shinikizo

Usambazaji wa shinikizo umejaribiwa na kurekebishwa vizuri kabla ya mashine kuondoka kiwandani. Katika kazi ya kawaida, ikiwa inaanza mapema sana au hakuna mwendo wowote, relay ya shinikizo inaweza kubadilishwa na kifungo mwishoni mwa relay ya shinikizo kwa manually; kuongeza shinikizo kwa mwendo wa saa na kupunguza shinikizo kwa njia ya kinyume cha saa.

5, Ilani:

A, kiwango cha mafuta kwenye upande wa chini, kichujio cha mafuta ya kunyonya kitavuta hewa kwa urahisi na mfumo utatetemeka na suluhisho ni: kujaza mafuta kwenye tanki la mafuta na kuruhusu kiwango cha mafuta juu ya kiashirio cha kioevu na tanki ya mafuta ya idling mara kadhaa kutoa hewa nje ya tangi.

B, Safisha chujio cha mafuta ya kunyonya kila baada ya miezi 6.

C, voltage ya valve solenoid directional na valve solenoid kufurika ni 220V, hivyo kuhakikisha voltage si chini ya 220V.

Electric controls system

Waya wa kuingiza ni waya wa awamu ya nne na saizi ni 2.5²mm; Unganisha waya wa ingizo la umeme na laini ya sifuri ya 220VAC, awamu ya 3 50Hz kwenye kisanduku cha waya cha ingizo upande wa juu kulia wa mashine na uikose kulingana na kanuni za umeme.

Warning: the machine must be safely grounded!

Installation and commission

1 Ufungaji

Ardhi lazima iwe gorofa na laini na tafadhali funga miguu ya mashine. Bomba la utoaji na kipenyo cha valve haipaswi kuwa chini ya φ10, shinikizo ni 1.6 ~ 2.0MPa na bomba la kioevu lazima liwekewe maboksi.  

Warning: dry ice making shop should be well ventilated!

2 anzisha mashine ya barafu

    (1) fungua sanduku la umeme, sukuma kwenye kivunja mzunguko wa shunt;

    (2) washa nguvu kuu kwenye kisanduku cha waya cha kuingiza;

    (3) fungua kitufe cha "acha" kwenye ubao;

(4) anza injini ya pampu ya mafuta kwenye skrini ya kugusa;

(5) fanya kazi kwenye skrini ya kugusa kwa hatua zote.

Note: A.please observe if the motor runs clockwise during first time start.

B.after starting oil pump, you can manually adjust hydraulic system pressure and switch action pressure; system pressure is 21MPa when machine leaving factory.

    Warning: It is strictly prohibited to reverse the oil pump

     (6) kuweka muda wa kulisha na shinikizo la kubakiza wakati kulingana na mahitaji ya usindikaji;

     (7) chagua hali ya uendeshaji ya mwongozo au otomatiki;

     (8) zima nguvu zote baada ya kazi.

Operation

Vali 1 ya kwanza fungua mwenyewe ya bomba la kioevu nje na uruhusu kioevu Co2 ingie kwenye mashine.

2, kisha kuanza nguvu, pampu ya mafuta, kuchanganya motor; bonyeza silinda kuu mbele na nyuma, kulisha sekunde 10, kisha bonyeza silinda kuu inayoendelea na nyuma, kulisha sekunde 10, na kurudia kitendo kama hicho mara kadhaa.

Note: Feeding action is only started when main oil cylinder is at rear end;

Automation action is only started when main oil cylinder is back to end.

       3, Barafu kavu itafanywa kiotomatiki wakati sanduku la mgandamizo limepozwa kabisa.

Notice: each time start machine, there is a lot of Co2 gas existing in pipes, users must blow compression box and dew by the Co2 gas.

4, Kurekebisha barafu kavu

A, rekebisha utoaji wa barafu kavu kwa kurekebisha ongeza kigezo cha muda cha Co2: kigezo cha kurekebisha cha YGBK-50-1 ni 0.4-0.5KG. Ikiwa ni chini ya 0.45kg, itaathiri uzalishaji wa barafu na ikiwa ni zaidi ya kilo 0.5, itasababisha utokaji wa gesi ya Co2 na mbaya kwa mashine.

B, kurekebisha ukubwa wa barafu kavu

Urefu wa barafu kavu inaweza kubadilishwa na kasi ya kurekebisha ya kuchanganya motor.

Ukungu tofauti unaweza kutoa saizi tofauti ya pellets kavu za barafu kutokaΦ3-Φ16.

Warning:

A Piston must be pushed at bottom when feed manually.      

B when feeding solenoid valve cannot shut off, shut off feed ball valve (offered by user )immediately. C ice output at one time cannot exceed 0.5kg.

C it is forbidden to put your hands near the closing door of the compression box when the oil pump is running.

D Co2 is not toxic but high-density Co2 can make people suffocate; so it is necessary to keep dry ice factory well ventilated.

 E solid form of Co2-dry ice, minus 78℃, can easily frostbite skins, so suitable insulation measures are a must when touch dry ice.

D dry ice easily sublimates and its expansion rate is 600 when it changes to gas; so it is not right to store dry ice in a completely sealed place with no gas out way.

Maintenance

1Inapaswa kusafisha kioevu cha Co2 katika mabomba yote mashine inapoacha kufanya kazi; baada ya umeme kukatika, inapaswa kusafisha mwili wa mashine na kuifuta kwa kitambaa.

2 Angalia ikiwa mafuta yanavuja; ikiwa mafuta yanavuja, kaza screws au ubadilishe pete ya kuziba.

3Angalia ikiwa rangi imezimwa; ikiwa kuna rangi, piga rangi ikiwa kuna kutu.
