Ko kudzvanywa kwemutyairi kunobata sei vharuvhu yekuenzanisa?

2024-03-14

The pilot ratio of the counterbalance valve is the ratio of the pilot area and the overflow area, zvinoreva kuti kukosha uku kwakaenzanawo ne: apo counterbalance valve spring inotarwa kune yakagadziriswa kukosha, kumanikidzwa kunodiwa kuivhura kana pane. hapana mafuta ekutyaira uye mafuta ekutyaira ega anovhura iyo pressure ratio.

 

Kana pasina mafuta ekumanikidza muchiteshi cheoiri chekutyaira, iyo yakadzikama yekuvhura kudzvanywa ndiyo kukosha kwekugadzika kwechirimo. Kana pasina mafuta ekufambisa ndege, chivharo chekuenzanisa chinovhurwa nemutoro, uye kudonha kwemhepo kuchawedzera zvakanyanya sezvo kuyerera kunowedzera (izvi zvinoshandiswawo kuenzanisa mutoro). Kana pesvedzero yekumanikidza yekubuda ikasatariswa, iyo pilot pressure = (set value - load) / area ratio. Kana mutyairi wemukati akashandiswa, mhepo yekuvhura inogona kuiswa nekugadzirisa bhoti yevhavha yekuyamura.

 

chaiyo formula
Kuvhura dzvinyiriro = (seta kudzvanywa - yakanyanya mutoro kumanikidza) / mutyairi chiyero chevhavha

Ko kudzvanywa kwemutyairi kunobata sei vharuvhu yekuenzanisa?

Payevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhare kana 3:1, pane 3:1 hukama hwakaenzana pakati pemafuta ekufambisa ndege nenzvimbo yekutsikirira inoenderana neoiri inlet yekuvhura valve core, saka kudzora kunodiwa kuvhura core yevhavha. inofanira kunge yakaderera, uye kutonga The ratio of pressure to pressure iyo oiri inlet inovhura spool inenge 1:3.

 

Leading Ratio

3: 1 (yakajairwa) Inokodzera mamiriro ane hombe shanduko shanduko uye kugadzikana kweinjiniya michina mitoro.

8: 1 inokodzera mamiriro apo chinodiwa chemutoro chinoramba chiripo.

 

Mamiriro ekushanda akasiyana uye nharaunda zvinoda sarudzo dzakasiyana dzekumanikidza reshiyo. Kana mutoro uri nyore uye kupindira kwekunze kuri kudiki, yakakura hydraulic control ratio inowanzosarudzwa, iyo inogona kudzikisa kukosha kwemutyairi uye kuchengetedza simba. Mumamiriro ezvinhu ane kukanganiswa kukuru kwemutoro uye kuzunguzika kuri nyore, diki diki reshiyo inosarudzwa kuti ive nechokwadi chekuti kuchinjika kwemutyairi hakuzokonzerese kuzunguzika kweiyo.counterbalance valvecore.

 

Zvinhu zvekucherekedza kana uchisarudza counterbalancing valve:

1. Chiyero chekuyerera chinogona kunge chakakwirira zvishoma kudarika chiyero chekuyerera;
2. Shandisa valve ine chiyero chepilot yakaderera sezvinobvira, iyo inonyanya kugadzikana;
3. Ivhavha yekuenzanisa inoshandiswa kudzora kudzvinyirira, kwete kukurumidza;
4. Madzvinyiriro ose akaiswa ari kuzarura dzvinyiriro;
5. Haikwanise kushandiswa sevhavha yekuyamura;
6. Ramba uri pedyo neactuator sezvinobvira kudzivirira hose kubva pakuputika.
