years later, there are a lot of mold temperature machine industry clients to ask scheme selection problem, that today's job is to look at the mold industry mold temperature machine high temperature centrifugal pump selection problem. Now the most common mould industry is Germany's century-old enterprise SPECK brand high temperature magnetic pump ( Centrifugal pump) SPECK brand magnetic pump, Germany because of high efficiency and energy saving and long life looks small, so the market sell like hot cakes, so die temperature machine industry selection of high temperature magnetic pump, we must first understand what?

a corresponding mold, high temperature magnetic pump inward and outward dimensions, such as a few into a few out? A few loop?

device system piping layout condition refers to send liquid height conveying liquid from liquid to, such as absorption side the lowest level, such as the highest level of discharge side length, some data and piping specifications and materials, pipe specification, quantity, etc. , comb for department head and NPSH checking calculation.

2, high temperature magnetic pump operating point ( Flow head) 吗?

1。 Traffic is one of the important performance data of heat water pump, it is directly related to the entire plant production capacity and transmission capacity. Such as design process design can calculate a normal, minimum, maximum three flow pump. Choosing pump, based on maximum flow, normal flow, give attention to two or morethings when there is no maximum flow, usually desirable to normal flow rate of 1. 1 times as the maximum flow.

2。 The required lift device system, is another important performance data of pump, general with 5% - Head to selection after 10% allowance.

3, high temperature magnetic pump transmission medium?

liquid properties, including the name of the liquid medium, physical properties, chemical properties and other properties, physical properties with temperature c, d, density, viscosity, u, solid particle diameter and gas content in the medium and so on, this is related to the system of the head, effective computing cavitation allowance and appropriate pump type: chemical properties, mainly refers to the chemical corrosion resistance and toxicity of liquid medium, is to choose what kind of shaft seal material selection and heat conduction oil pump type of important basis.

4, high temperature magnetic pump operating conditions ( Temperature) 吗? Many

the content of the operating conditions, such as the operation of the liquid T p, suction side pressure saturated steam force PS ( Absolute) , discharge side pressure container PZ, altitude, the environment temperature is clearance or continuous operation, the position of the heat pump is a fixed or movable.

5, 50 hz or 60 hz high temperature magnetic pump?

wham mold temperature machine commonly used models of German SPECK, magnetic pump series Y - such as TM Magnetic pump, 4081 - Y Centrifugal pump and CY - 2051 Mk 4281 high temperature magnetic pump, their average water temperature from 140 degrees to water temperature, maximum temperature 220 degrees 350 degrees of oil and water, the water quality requirement is without impurities, no calcification. High temperature centrifugal water pump is the core focus in die temperature machine, the equivalent of the heart, must choose the right, and the correct use of the long term, if really don't understand can contact the professional engineering company, select the appropriate pump to make mold temperature machine is more efficient.
