It is suitable for conveying high-temperature liquid without solid particles. When selecting the pump, take the maximum flow as the basis and take into account the normal flow. When there is no maximum flow, it is usually 1.1 times the normal flow as the maximum flow.
I. Liquid properties, including the name of the liquid medium, physical properties, chemical properties and other properties, physical properties are temperature C density D, viscosity U, solid particle diameter and gas content in the medium, which relates to the head of the system, effective cavitation margin calculation and appropriate pump type: Chemical properties, mainly refers to the chemical corrosion and toxicity of liquid medium, is an important basis for the selection of thermal oil pump materials and the selection of a type of shaft seal.
Two. The head required by the device system is another important performance data of the pump, and it is generally used to enlarge the head by 5%-10% margin to select the type. So what are the selection methods of heat conduction oil pump? Such as design institute process design can calculate the pump normal, minimum, maximum three kinds of flow. The hot oil pump has reasonable structure, excellent performance and reliable operation.
There are many contents of operating conditions, such as liquid operation T saturated steam force P, suction side pressure PS (absolute), discharge side container pressure PZ, altitude, ambient temperature operation is clearance or continuous, the position of high temperature heat conduction oil pump is fixed or removable.
Heat conduction oil pump is an ideal hot oil circulation pump or heat carrier pump, is the ideal supporting pump for heat exchange equipment. Five. The pipe layout conditions of the device system refers to the liquid feeding height liquid feeding distance liquid feeding direction, such as the suction side of the lowest liquid level, the discharge side of the highest liquid level and some data and pipeline specifications and their length, material, pipe fitting specifications, quantity, etc., in order to carry out the system head calculation and the check of the NPZ.
Four. Flow is one of the important performance data of heat conduction oil pump, which is directly related to the production capacity and transportation capacity of the whole device.
The above is the heat conduction oil pump selection should pay attention to, I hope to give you help.
