Bơm chân không LPH 55312, LPH 55316, LPH 55320


Bơm chân không (Liquid Ring Vacuum Pumps) SIHI LPH 55312, LPH 55316, LPH 55320 là dạng bơm chân không 2 cánh bơm dùng vòng nước để làm kín, được dùng rộng rãi trong các ngành công nghiệp do có độ tin cậy cao, có cấu tạo đơn giản và kết cấu vững chắc. Dòng bơm chân không này có thể dùng như một máy nén mà không chỉnh sửa thêm nữa.

LPHX 55312, LPHX 55316, LPHX 55320 có áp suất làm việc từ 33 mbar đến 1013 mbar, lưu lượng hút đạt được từ 130 m3/h đến 560 m3/h

LPHX 55312, LPHX 55316, LPHX 55320 là dòng bơm cung cấp riêng lẻ với động cơ nên có thể đặt hàng thân bơm riêng (bare shaft pump) và tự lắp ráp động cơ (motor) theo yêu cầu riêng 
hoặc ráp láp trọn bộ (complete pump) từ hãng 
hoặc từ đại lý ủy quyền SIHI ở Việt Nam để có báo giá phù hợp hơn.
CONSTRUCTION
Sterling SIHI liquid ring vacuum pumps have a simple but robust
construction with the following features and benefits:
Near isothermal compression
Oil free, with no internal lubrication
Capable of handling almost all gases and vapours
Able to handle quantities of liquid “carry over”
Low maintenance and safe operation
Low noise and almost vibration free
Available in a wide range of materials
Broad range of applications
O-ring sealing as standard
Cavitation protection as standard
Drain hole as standard
Built-in solids drain
Rotating metallic parts are non contacting to minimise wear
ATEX compliance
Sterling SIHI liquid ring vacuum pumps of the range LPH 55312,
LPH 55316 and LPH 55320 are two stage pumps.

APPLICATIONS
Evacuation and pumping of dry gases and saturated vapours. The
pumps can also handle liquids. These units offer pressures in the
range of 33...900 mbar(a) to atmospheric. Much lower pressures
are available by using ancillaries such as ejectors and lobular
boosting pumps. Typical application areas include:
Chemical and pharmaceutical industry for distillation, drying
and degassing
Food and beverage industry for low temperature cooking,
and bottle filling
Electronic industry for impregnation and drying
Plastics & Rubber industry for degassing
Healthcare for sterilisers and general vacuum

Note
By continuously feeding the pump with a small amount of service
liquid (usually water), the heat due to gas/vapour compression is
conducted away. This also replenishes the liquid ring and ensures
that it does not become saturated with process media. Recharging
the pump with service liquid at ambient temperature enables the
unit to condense evacuated gases / vapours. It can therefore be
used for solvent recovery. The condensed gas and liquid can be
separated in a liquid separator. More information is provided in the
accessory catalogues.
The integrated solids drain permits the removal of any entrained
solids whilst the pump is operating. The service liquid can therefore,
simply be re-circulated. The rotation of the pump is clockwise when
viewed from the drive end.
