進口不銹鋼臥式沖壓離心泵概述：

    不銹鋼臥式沖壓離心泵是一種適應范圍較廣的多功能產品，可以輸送各種包括水或工業(yè)液體在內的不同介質，適用于不同溫度、流量和壓力范圍。
其典型應用主要包括以下方面：
供水：水廠過濾、輸送及分區(qū)送水和主管增壓；工業(yè)增壓：流程水系統(tǒng)、清洗系統(tǒng)；工業(yè)液體輸送：鍋爐給水、冷凝系統(tǒng)、冷卻和空調系統(tǒng)、機床配套、酸堿輸送；水處理：蒸餾系統(tǒng)或分離器、游泳池等；農田灌溉、石油化工、醫(yī)藥衛(wèi)生等。

進口不銹鋼臥式沖壓離心泵安裝條件

不銹鋼臥式沖壓離心泵為泵軸直聯(lián)型聯(lián)結，由泵、泵軸和標準電機組成：·泵應安裝在通風且防冰凍的地方；·泵的安裝要保證在使用時泵不受系統(tǒng)管路的張力影響；·如果泵安裝在戶外，必須配置合適的外罩以防止電氣元件進水或凝露；·為了方便于檢查和維修，在機組的周圍應必須留有足夠的空間；·電氣接線裝置應保證泵不受缺相、電壓不穩(wěn)、漏電和過載的損害；·泵應水平安裝在基座上，水平方向為泵的吸入口，垂直方向為泵的排出口。

如果泵中的壓力低于輸送液體的蒸汽壓力，可能發(fā)生氣蝕，為避免氣蝕，確保泵進口側有zui小壓力，zui大吸程H[m]可按下式計算：H=Pb×10.2-NPSH-Hf-Hv-Hs．Pb-大氣壓(巴)在閉式管路中可以認為是閉式系統(tǒng)的系統(tǒng)壓力(巴)。

NPSH一凈正吸入壓頭(米)可以在性能曲線中NPSH曲線上對應于zui大流量處讀出。Hf-入口處的管路損失(米)其是對應于管路可能產生的zui大流量時的值。Hv-液體的汽化壓力(米)其值的大小取決于液體的溫度和液體的汽化壓力值。Hs-安全余量(米)zui小為0.5米壓頭通過計算，如果“H”為正值，說明泵可以在zui大吸程“H”的情況下運行；如果“H”為負值，說明泵必須要在進口有一個zui小壓力為“H”米的壓頭的情況下才可以正常運行。注：一般情況下不進行以上計算。只有在下列情況下使用泵時才要對“H”進行計算：1、液體溫度較高2、液體流速超過了額定值3、吸程較大或進口管路較長4、系統(tǒng)壓力太小5、進口條件較差

Stainless steel horizontal centrifugal pump

British imports of stainless steel imports horizontal stamping centrifugal pump Stainless steel horizontal centrifugal pump

Introduction of imported stainless steel horizontal centrifugal pump:

Stainless steel stamping horizontal centrifugal pump is a kind of multi-function products to adapt to a wide range, can transport all kinds of different media including water or industrial liquid, suitable for different range of temperature, flow and pressure.

Its typical applications include the following aspects:

Water supply: water filter, bottled water and charge transport and area booster; industrial pressure: process water system, cleaning system; industrial liquid conveying: boiler feed water, condensate systems, cooling and air conditioning systems, machine matching, acid-base transport; water treatment: distillation system or separator, swimming pool; irrigation, petroleum chemical industry, medicine health.

Stainless steel horizontal centrifugal pump

Stainless steel stamping horizontal centrifugal pump for pump shaft direct connection, composed of pump, pump shaft and standard motor - pump should be installed in the ventilation and anti freezing place; and the installation of the pump to ensure the tension of the pump will not be influenced by the pipeline system; and if the pump is installed outdoor, must be equipped with the appropriate the cover to prevent water condensation or electrical components; in order to facilitate inspection and maintenance, enough space must be left in the peripheral unit; and electrical wiring device shall guarantee that the pump is not affected by the lack of phase, voltage instability, leakage and overload; - pump should be installed horizontally on the base, the horizontal direction the suction pump, vertical pump outlet.

If the pump pressure lower than the vapor pressure of liquid, cavitation may occur, in order to avoid cavitation, ensure the pump inlet side has the minimum pressure, the maximum suction lift of H[m] can be calculated as follows: H=Pb * 10.2-NPSH-Hf-Hv-Hs.Pb- (BA) atmospheric pressure in the closed pipeline can be considered the system pressure of closed system (Pakistan).

NPSH a net positive suction head (meter) can be read in the performance curve NPSH curve corresponds to the maximum flow. The loss of the pipe at the entrance to the Hf- is the value corresponding to the maximum flow of the pipeline. The value of the vaporization pressure (Hv-) of a liquid depends on the temperature of the liquid and the vapor pressure of the liquid. Hs- safety margin (m) for a minimum of 0.5 meters head through the calculation, if "H" is positive, indicating the maximum suction pump can be in "H" under the condition of operation; if "H" is negative, that the pump must have a minimum pressure head pressure to "H" in imported meters circumstances can the normal operation. Note: generally do not calculate above. "H" is calculated to use only the pump under the following conditions: 1, 2, high temperature of the liquid flow rate of the liquid exceeds the rated value of 3, or larger suction inlet pipeline system pressure is too small, long 4, 5 import conditions

Stainless steel horizontal centrifugal pump

Stainless steel horizontal stamping centrifugal pump thin, clean, non flammable and does not contain solid particles and fibers of the liquid; temperature between -20 DEG to +100 DEG C liquid; ambient temperature up to +40 DEG C; the highest elevation of 1000 meters; the highest pressure system 10bar.

The motor is fully enclosed, air-cooled diode standard motor; protection grade: IP55; insulation: F; standard voltage: 50Hz 1 * 220V 3 * 380V
