    Glacfar le míreanna a fhillfear laistigh de 40 lá ón dáta a fhaigheann tú na hearraí. Ní féidir míreanna saincheaptha a fhillt nó a mhalartú. Ní féidir míreanna a ceannaíodh le cárta bronntanais leictreonach a fhillt; ní bhaineann aisíocaíochtaí leo.

Faoi imthosca speisialta, déanfar moill air mar seo a leanas: Nuair a chuireann tú ordú Dé Sathairn, Dé Domhnaigh nó laethanta saoire poiblí, déanfar moill 2 lá air.De ghnáth, teastaíonn 5-7 lá oibre (Dé Luain go Dé hAoine) gan a bheith faoi thionchar moill eitilte nó tosca comhshaoil eile.Toisc go bhfuil ár seirbhís loingseoireachta ar fud an domhain, beidh amanna seachadta ag brath ar do shuíomh, mar sin d'fhéadfadh sé go mbeadh cúpla uair ag teastáil agus fan go foighneach má tá tú i gceantair nó tíortha iargúlta.

Ní ghlactar le míreanna díolacha deiridh nó bronntanais saor in aisce le fillt.Chun bheith incháilithe le fillt, ní mór do mhír a bheith gan úsáid agus sa chéad chaoi a fuair tú í. Ní mór í a bheith sa phacáistiú bunaidh freisin.Tar éis treoracha fillte a fháil uainn, déan do mhíreanna fillte a phacáistiú agus do phacáiste a scaoileadh ag oifig an phoist áitiúil nó ag seachadóir eile.

Déanfar an t-aisíoc a phróiseáil agus a chreidiúint go huathoibríoch chuig do bhunmhodh íocaíochta.Ní féidir aon fhillt nó malartuithe a ghlacadh má táirgeadh an táirge go saincheaptha, lena n-áirítear méid saincheaptha, dath saincheaptha, nó cló saincheaptha.An bhfuil cabhair bhreise uait, déan teagmháil linn. service@roymall.com nó Whatsapp: +447549870296

    Description:
    This HX-15 Stirling helicopter engine model adopts a 16-cylinder swash plate Stirling cold and hot cylinder opposing structure. This cold cylinder and hot cylinder opposing structure is conducive to preventing heat conduction between cold and hot cylinders, improving the heat exchange capacity of the engine, keeping the temperature difference of the engine lasting, and making the output power more stable.
    The use of glass with a hardness exceeding that of metal as the cylinder piston reduces the weight of the piston, improves the sealing and wear resistance of the cylinder piston, and is not easy to damage the surface due to high-speed operation, and will not rust, and is super hard and maintenance-free.
    The power output transmission of this mechanical structure is also very intuitive. The movement direction of the piston of the opposing cylinder, the two circular gears change the speed ratio, and the four bevel gears change the power output direction by 90°, and transmit the power to the main propeller of the helicopter and the small propeller at the tail, respectively, so that the mechanical structure is intuitively reflected.
