Pam Air Tekanan Malar Pemacu Kekerapan
Spesifikasi teknikal
- Larian yang munasabah, dengan permulaan yang lembut dan hentian lembut, boleh menghilangkan kesan tukul air. Oleh itu, tork dan haus aci motor purata akan dikurangkan dengan banyak. Bukan sahaja mengurangkan kos penyelenggaraan, tetapi ia juga meningkatkan jangka hayat pam dan keseluruhan sistem bekalan air.
- Sistem bekalan air tekanan malar terus mendapat air daripada sumber air, jadi ia mengurangkan pencemaran sekunder yang berkesan untuk mencegah banyak penularan penyakit berjangkit.
- Ia mempunyai fleksibiliti konfigurasi yang tinggi, tahap automasi yang tinggi, fungsi yang kaya dan prestasi yang stabil.
- Ia adalah kawasan perakaunan yang kecil, pelaburan yang kurang dan kecekapan kerja yang tinggi
- Jimat tenaga: pam VSD boleh membantu anda menjimatkan 20 peratus -60 peratus elektrik dan air yang mesra alam.
- Kawalan komunikasi: VFD pam boleh membantu anda mencapai kawalan tanpa pengawasan, menjimatkan tenaga kerja.
Permohonan
Pam air pemacu frekuensi digunakan secara meluas dalam sistem bekalan air tekanan malar, radas pemadam kebakaran, sistem bekalan air bangunan tinggi, peralatan rawatan air, kejuruteraan alam sekitar dan lebih banyak kawasan.
