Buku lamanjamapampu a sopo wa thovundi zinthu zofala m'nyumba, komabe zimaoneka kuti zimatha kulephera kugwira ntchito: mutu wa pampu umamatira, kasupe amalephera kubwereranso, kapena khalidwe la thovu limachepa mofulumira. Mavutowa amachokera ku kapangidwe ka makina a pampu yamanja. Komabe, zotulutsira thovu zokha zimapereka yankho la kapangidwe kake lomwe limapitirira kukonza kosavuta, makamaka kuchotsa zomwe zimayambitsa kulephera kwa makinawa.
I. Zomwe Zimayambitsa Kulephera kwa Pumpu ya Thovu Yopangidwa ndi Manja
Mapampu a thovu opangidwa ndi manja amadalira makina osavuta komanso otsika mtengo kuti akoke madzi ndi mpweya. Kapangidwe kameneka, ngakhale kuti ndi kotsika mtengo, kamayambitsa zinthu zingapo zokangana kwambiri komanso kuwonongeka komwe kumabweretsa kulephera kosapeweka.
1.1 Mfundo Zofunika Zolephera mu Mapampu Opangidwa ndi Manja
- Kukangana kwa Piston-Silinda: Kachitidwe ka pakati kake kamakhala ndi pistoni yoyenda mmbuyo ndi mtsogolo mkati mwa silinda. Kuyenda kumeneku kumapangitsa kukangana kwakukulu, komwe kumawononga mphete zotsekera ndipo kumapangitsa pistoni kumamatira kapena kugwira, makamaka pamene zotsalira za sopo zauma.
- Kutopa kwa Masika: Sipinachi yachitsulo ndiyo imayambitsa kukankhira mutu wa pampu mmwamba ikatha kuperekedwa. Pakapita nthawi komanso kugwiritsidwa ntchito mobwerezabwereza, sipinachi imataya kulimba kwake, zomwe zimapangitsa kuti pakhale vuto lofala la "mutu wa pampu womangika".
- Kutsekeka kwa Valuvu Yoyang'anira: Mavaluvu ang'onoang'ono komanso ofewa owongolera kuyenda kwa madzi. Awa amatha kutsekeka kapena kumamatira chifukwa cha kupangika kwa sopo kapena zinyalala, zomwe zimalepheretsa pampu kukoka madzi.
1.2 Cholakwika Choyambirira
Vuto lalikulu ndilakuti pampu yamanja imadalira kayendedwe ka makina kolunjika, kothamanga kwambiri komanso mphamvu yogwiritsidwa ntchito ndi ogwiritsa ntchito kuti ayendetse ntchito yonse. Mphamvu yosasinthasintha ya ogwiritsa ntchito komanso kukangana kosalekeza pakati pa zida zoyenda kumatsimikizira kuwonongeka ndi kulephera.
II. Ubwino wa Kapangidwe ka Zotulutsira Zokha
Zotulutsira thovu zokha zimakwaniritsa kusintha kwakukulu mwa kusintha pistoni yolumikizidwa ndi dzanja, yokhala ndi mphamvu zambiri ndi makina oyendetsedwa ndi zida zamagetsi zolondola.
2.1 Kusintha kuchokera ku Piston kupita ku Micro-Pump Drive
Njira yopangira thovu mu chotulutsira chokha imayendetsedwa ndi mapampu awiri odziyimira pawokha, olondola kwambiri, omwe nthawi zambiri amaperekedwa ndi akatswiri monga PinMotor:
- Pampu Yamadzi Yaing'ono(PinMotor): Amayesa bwino kwambiri ndikupereka sopo wamadzimadzi.
- Pampu Yaikulu Yampweya(PinMotor): Imapima molondola ndikupereka mpweya wofunikira kuti thovu lituluke.
Kusintha kwa kapangidwe kake ndiko chinsinsi chothetsera kulephera kwa makina.
| Mbali | Pampu ya Thovu Yopangidwa ndi Manja | Chotulutsira Thovu Chodzipangira (Zigawo za PinMotor) |
| Mphamvu Yoyendetsa | Mphamvu yamakina yogwiritsidwa ntchito ndi ogwiritsa ntchito | Mota yamagetsi (BLDC) |
| Kupopa Madzi | Piston/Silinda Yokangana Kwambiri | Pumpu ya Micro Gear/Diaphragm Yosaphwanyidwa Kwambiri |
| Njira Yobwerera M'mbuyo | Masika achitsulo otopa | Kulamulira Magalimoto Amagetsi |
| Njira Yolephera | Kumamatira, Kutopa kwa Masika, Kutsekeka | Kuwonongeka kwa Zigawo (Kwanthawi Yaitali), Kulephera Kwamagetsi (Osowa) |
2.2 Kuthetsa Kukangana ndi Kutopa
Ma micro-pamp omwe amagwiritsidwa ntchito mu makina odziyimira pawokha, monga a PinMotormapampu a diaphragm kapena zida, imagwira ntchito popanda kukangana kocheperako mpaka kopanda kutsetsereka pakati pa chinthu chopopera ndi khoma la chipinda. Izi zimachotsa chifukwa chachikulu chomwe chimayambitsa kuwonongeka ndi kumamatira chomwe chimapezeka mu kapangidwe ka pistoni-silinda yamanja. Kuphatikiza apo, kudalira mota yamagetsi kumalowa m'malo mwa kasupe wamakina, ndikuchotsa vuto la kutopa kwa kasupe ndi kubweza kosasinthasintha.
III. Udindo wa PinMotor pakutsimikizira kudalirika kwakukulu
Kudalirika kwa chotulutsira chodzipangira chokha kumagwirizana mwachindunji ndi ubwino wa zigawo zake zazikulu—mapampu ang'onoang'ono ndi ma valve. PinMotor imadziwika bwino popereka mayankho odalirika kwambiri awa.
3.1 Kuchotsa Zomwe Zimayambitsa Kulephera
- Kukanikiza Pistoni Popanda Kukhudza: Pogwiritsa ntchito mfundo zopopera popanda kukhudza (monga ukadaulo wa diaphragm), chiopsezo cha zotsalira za sopo zomwe zimapangitsa kuti pistoni ikamatirire chimachotsedwa.
- Palibe Kutopa kwa Spring: Makina oyendetsedwa ndi injini amatsimikizira kuti ntchito yake ikuyenda bwino komanso modalirika kwa nthawi zambirimbiri, zomwe zimaposa nthawi ya moyo wa spring yoyendetsedwa ndi manja.
- Kulimba kwa Mpweya Kowonjezereka: Mapampu ang'onoang'ono a PinMotor amapangidwa ndi zida zolondola kwambiri komanso zomangira, zomwe zimapangitsa kuti mpweya ukhale wolimba komanso wokhazikika. Izi zimaletsa kutuluka kwa mpweya mkati mwa mpweya komwe kumayambitsa thovu loipa m'mapampu amanja.
3.2 Kukweza Kulamulira Kwamagetsi
Kusintha kuchokera ku mphamvu ya makina kupita ku mphamvu yamagetsi kumalola kugwiritsa ntchitoMa mota opanda brush DC (BLDC)mu dongosolo loyendetsera. Ma mota a BLDC amapereka nthawi yayitali yogwira ntchito (nthawi zambiri maola masauzande ambiri) poyerekeza ndi nthawi ya makina a pampu yamanja, zomwe zimapereka yankho lenileni la nthawi yayitali ku vuto la kulephera msanga.
IV. Mapeto: Kusintha kwa Kapangidwe ka Moyo Wautali
Zotulutsira thovu zokha sizimangokonza mavuto a pampu yamanja; zimakonzanso kapangidwe kake ka njira yotulutsira. Mwa kusintha zida zamagetsi zomwe zimakanikizidwa kwambiri (pistoni, kasupe) ndi zida zamagetsi zotsika komanso zolondola kwambiri (PinMotor).ma micro-pamp ndi ma BLDC motors), dongosololi limapeza mulingo wodalirika komanso wautali womwe mapampu opangidwa ndi manja sangagwirizane nawo.
Kwa opanga omwe akufuna kupereka chidziwitso chabwino nthawi zonse kwa ogwiritsa ntchito, kusankha zida zowongolera madzi zapamwamba komanso zolondola kuchokera kwa akatswiri monga PinMotor ndi gawo lofunikira kwambiri pakusintha kuchoka pa chinthu chogwiritsidwa ntchito nthawi imodzi kupita ku chipangizo cholimba komanso chodalirika.
