The key to installing a centrifugal pump is to determine the installation height
Food Additives
Food additives are substances added to food to preserve flavor or enhance taste, appearance, or other sensory qualities. Some additives have been used for centuries as part of an effort to preserve food, for example vinegar (pickling), salt (salting), smoke (smoking), Msg sugar (crystallization), etc. This allows for longer-lasting Refined Glycerine foods such as bacon, sweets or wines. With the advent of processed foods in the second half of the twentieth century,Titanium Dioxide many additives have been introduced, of both natural and artificial origin. Food additives also include substances that may be introduced to food indirectly Monosodium Glutamate (called "indirect additives") in the manufacturing process, through packaging, or during Gelatin Food Grade storage or transport.
Food additives can be divided into several groups, Sodium Hexametaphosphate although there is some overlap because some additives exert more than one effect. For example, salt is both a preservative as well as Refined Gglycerine 99.5% Food Grade a flavor.
To regulate these additives and inform consumers, each additive is assigned a unique number called an "E number", which is used in Europe for all approved additives. This numbering scheme has now been adopted and extended by the Codex Alimentarius Commission to internationally identify all additives,regardless of whether they are approved for use.

It should be noted that the centrifugal pump installation site elevation and water temperature is different from the test conditions, such as the local elevation of 300 meters or more than 20 degrees Celsius was pumped water, the calculated value to be amended. Ie atmospheric pressure at different elevations and saturated vapor pressure above 20 degrees Celsius. However, when the water temperature is below 20 degrees Celsius, the saturated steam pressure is negligible.
From the pipeline installation technology, water pipes require strict sealing, can not leak, leaking, otherwise it will undermine the centrifugal pump inlet at the vacuum, so that the water pump to reduce the amount of water is not even pumping too serious. Therefore, we should conscientiously do the work of the interface of the pipeline to ensure the construction quality of pipeline connection.
