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.
