MMENE MA PNEUMATIC MACHITIDWE OPAMBANA KULEMERA KWA KATUNDU WOKWEZEDWA

Zipangizo zoyendetsera mpweya zimayendetsedwa ndi mphamvu ya mpweya (mpweya wopanikizika) ndipo mayendedwe a zida zogwirira amayendetsedwa ndi ma valve a mpweya.

Malo a choyezera kuthamanga ndi valavu yosinthira zimasiyana malinga ndi kapangidwe ka zida zolumikizira katundu. Kusintha kwamanja kumagwiritsidwa ntchito poyendetsa katundu wokhala ndi kulemera komweko kwa nthawi yayitali. Pa nthawi yoyamba yoyendetsera, kuthamanga kwa balance kumasinthidwa pamanja ndi valavu yosinthira. Kudzasinthidwanso pokhapokha poyendetsa katundu wokhala ndi kulemera kosiyana. Kuthamanga kwa balance kumagwira ntchito mwanjira ina pa silinda ya system, ndikulinganiza katundu wokwezedwa. Pamene katundu wakwezedwa kapena kutsika pamanja, valavu yapadera ya pneumatic imasunga kuthamanga mu silinda kukhala kokhazikika, kotero kuti katunduyo akhale mu "balance" yabwino kwambiri. Katunduyo amatulutsidwa pokhapokha akayikidwa pansi, apo ayi amatsitsidwa mu "braked" mode mpaka atayikidwa pansi. Kusintha kwa kuthamanga kwa balance: Ngati kulemera kwa katundu kumasintha kapena katundu wakwezedwa koyamba, kuthamanga kowongolera pa valavu yosinthira kuyenera kukhazikitsidwa pa zero. Izi zikuwonetsedwa ndi choyezera chapadera cha kuthamanga, ndipo njira yokhazikitsira ndi iyi: ikani kuthamanga kwa balance kufika pa zero pogwiritsa ntchito valavu yosinthira ndikuwona kuthamanga pa gauge; lumikizani katunduyo ku chida; dinani batani loti "likunyamula" (likhoza kukhala lofanana ndi batani loti "likulumikiza"); onjezerani mphamvu yokwanira potembenuza valavu yosinthira mpaka katundu atafika.

Chitetezo: Ngati mpweya walephera, makinawo amalola chida chogwirira kuyenda pang'onopang'ono mpaka chikafika pamalo oyimitsa makina kapena pansi (ponse pawiri "chodzaza" komanso "chosatsegula"). Kusuntha kwa mkono mozungulira mzere kumayendetsedwa ndi mabuleki (ma axles onyamula zida ndi osankha).
