The choice of heat pump technique -

heat pump for hot oil circulation water pump with high quality and heat pump, the pump is the ideal heat exchange equipment form a complete set, can transport high temperature liquid without solid particles. Using the heat water pump heating cooling structure, changed the conventional water cooling structure, make more reasonable structure, high efficiency, energy saving, optimize product performance and service reliability is greatly increased. On the choice of heat pump from the pipe layout, operation condition and characteristic of liquid, infusion volume and unit head five aspects to consider. Then will give you a detailed analysis of the choice of heat pump technique.

1。 Device system piping arrangement refers to the distance into the liquid height, into the liquid, liquid into the direction, side has the lowest level, exit side top level data, such as length, material, pipe fittings and pipe specifications and the specifications, quantity, etc. In order to calculate head and check the cavitation of the system.

2。 There are a lot of operating conditions, such as the operation of the liquid temperature, saturated steam force P, suction side pressure PS ( Absolute) , discharge side pressure container PZ, altitude and ambient temperature is intermittent or continuous operation, and the position of the high temperature heat conduction oil pump is fixed or mobile.

3。 Liquid properties, including the name of the liquid medium, physical properties, chemical properties and other properties, physical properties, including temperature, viscosity, density, D U C, solid particle diameter and the gas content in the medium. This is related to the system of the head, the calculation of effective NPSH and appropriate pump type: chemical properties, mainly refers to the chemical corrosion resistance and toxicity of liquid medium, is to choose the high temperature heat conduction oil pump shaft seal materials and use which kinds of important basis.

4。 Equipment system is the required lift pump selection of another important performance data. In general, the elevator should be in 5% After a 10%.

5。 Traffic is one of the important performance data of huizhou heat pump manufacturer, is directly related to the entire plant production capacity and transmission capacity. Design institute, for example, can be calculated in the process design is normal, the minimum and maximum flow pump type. Choosing a pump, which is based on the maximum flow and considering the normal flow. When there is no maximum flow, take 1 of normal flow. 1 times as the maximum flow.
