GB19854 standard explosion-proof lithium battery forklift compliance configuration requirements(larawan1)

Ang GB19854 ay ang pangunahing pamantayan na binuo ng aking bansa para sa mga sasakyang pang-industriya na lumalaban sa pagsabog. Nililinaw nito ang mga kinakailangan sa pagsunod para sa paggamit ng mga forklift ng baterya ng lithium na lumalaban sa pagsabog sa mga nasusunog at sumasabog na kapaligiran. Kailangang mahigpit na ipatupad ng mga negosyo ang mga detalye ng pagsasaayos upang matiyak ang kaligtasan sa pagpapatakbo.

Compliance configuration ng explosion-proof electrical system

Mga kinakailangan sa pagpili ng elemento na lumalaban sa pagsabog

Ang lahat ng mga de-koryenteng bahagi ay kailangang iakma sa uri ng kapaligirang hindi lumalaban sa pagsabog at pangkat ng temperatura na ginagamit ng mga forklift, at may kaukulang mga kwalipikasyon sa sertipikasyon na hindi lumalaban sa pagsabog upang matiyak na walang panganib ng pag-aapoy sa isang potensyal na sumasabog na kapaligiran ng gas. Ang bahagi ng mga kable ay dapat magpatibay ng isang explosion-proof na sealing structure upang maiwasan ang pagtagas ng mga electric spark na dulot ng pagkaluwag at pagkasira. Kasabay nito, ang mga electrical circuit ay kailangang nilagyan ng overload at short-circuit protection device upang maiwasan ang mga aksidente sa kaligtasan na dulot ng abnormal na kasalukuyang.

Mga kinakailangan sa antas ng proteksyon sa kuryente

Ang shell ng mga de-koryenteng kagamitan ay dapat matugunan ang kaukulang mga pamantayan sa antas ng proteksyon upang maiwasan ang pagpasok ng alikabok at likido at makaapekto sa normal na operasyon ng mga bahagi. Sa isang mahalumigmig o maalikabok, nasusunog at sumasabog na kapaligiran, ang antas ng proteksyon ay kailangang higit pang pagbutihin upang matiyak ang katatagan at explosion-proof na pagganap ng electrical system.

Mga eksklusibong kinakailangan sa pagsasaayos para sa kaligtasan ng baterya ng lithium

Istraktura ng proteksyon ng pagsabog ng baterya

Ang lithium battery pack ay kailangang nilagyan ng explosion-proof shell, na may mga katangian ng impact resistance at mataas na temperatura resistance. Kapag ang baterya ay may mga abnormal na kondisyon tulad ng thermal runaway, maaari nitong epektibong harangan ang diffusion ng apoy at explosive energy, at maiwasan ang mga aksidente sa pagsabog sa nakapaligid na kapaligiran. Kasabay nito, ang battery pack ay kailangang nilagyan ng pressure relief device upang mailabas ang presyon sa oras kapag ang panloob na presyon ay masyadong mataas upang mabawasan ang panganib ng pagsabog.

Mga kinakailangan sa pagsunod sa sistema ng pamamahala ng baterya

Ang sistema ng pamamahala ng baterya ay kailangang magkaroon ng maraming function ng proteksyon tulad ng overcharge, overdischarge, overcurrent, at overheating. Sinusubaybayan nito ang boltahe, kasalukuyang, at mga parameter ng temperatura ng baterya sa real time. Kapag may nakitang abnormal na data, awtomatiko nitong ia-activate ang mekanismo ng proteksyon upang putulin ang power supply upang maiwasan ang pagkabigo ng baterya na magdulot ng mga panganib sa kaligtasan. Bilang karagdagan, ang control circuit ng sistema ng pamamahala ng baterya ay dapat ding matugunan ang mga kinakailangan sa explosion-proof upang maiwasan ang mga electric spark na dulot ng mga electrical failure.

Proteksiyon na istraktura at pagsasaayos ng adaptasyon sa kapaligiran

Ang mga bahagi ng istrukturang metal ng forklift ay dapat magkaroon ng sapat na lakas at paglaban sa kaagnasan, at hindi madaling kapitan ng kaagnasan o pagpapapangit sa isang nasusunog at sumasabog na kapaligiran, upang maiwasan ang pagkabigo ng mga bahagi na hindi lumalaban sa pagsabog dahil sa pinsala sa istruktura. Ang mga operating parts ng forklift ay dapat gawa sa anti-static na materyales, at walang static na spark na bubuo kapag hinawakan ito ng operator. Kasabay nito, ang forklift ay dapat na nilagyan ng grounding device upang maalis ang mga static na singil sa oras.

Pagsubaybay at pagsasaayos ng sistema ng maagang babala

Kinakailangang mag-set up ng real-time na sistema ng pagsubaybay upang patuloy na masubaybayan ang integridad ng mga bahaging hindi lumalaban sa pagsabog, katayuan ng baterya, at mga parameter ng pagpapatakbo ng electrical system. Kapag nasira ang mga bahaging hindi lumalaban sa pagsabog, abnormal ang baterya, atbp., isang tunog at magaan na babala ang ibibigay sa oras upang paalalahanan ang mga operator na gumawa ng mga hakbang. Ang sistema ng maagang babala ay kailangang magkaroon ng malinaw na pagkilala at maaaring epektibong magpadala ng impormasyon ng babala sa isang maingay na kapaligiran sa pagtatrabaho.

Kapag ang mga negosyo ay nag-configure ng mga explosion-proof na lithium battery forklift, kailangan nilang sundin ang mga kinakailangan ng pamantayan ng GB19854 sa buong proseso, isa-isang ipatupad ang mga detalye ng pagsunod mula sa pagpili ng bahagi hanggang sa pagbuo ng system, at magsagawa ng regular na inspeksyon at pagpapanatili ng kagamitan upang matiyak na ang mga forklift ay palaging nakakatugon sa mga pamantayan sa kaligtasan na lumalaban sa pagsabog at tinitiyak ang nasusunog at sumasabog na kaligtasan.
