1.Polish hasasy, sorujy çybyk we şöhle asýan bilen baglanyşykly ýörite sorujy çybykdyr. Ol sorujy çybygyň ýokarsynda, iň güýçli bolmaly, şonuň üçin has uly diametri we sorujy taýakdan has ýokary polat derejesi we üstü gaty tekiz.
2. Esasy funksiýa:
Guýyny möhürlemek we nebitiň, gazyň, suwuň açylmagynyň öňüni almak üçin gaplaýyş gutusyna goýlan gaplamalar bilen birleşdirilýär.
Siňdiriji çybyk bilen gatyr kellesiniň arasynda wagtlaýyn birleşdiriji
Görkezijiniň diagramma synagy.
Nasos urmagy, nasos sazlamasyny kadalaşdyrmak ýaly dürli guýy amallaryny tamamlaň.
