The opening of the stainless steel pump is mainly considering the model of the pump in the aspects of liquid conveying, device raising, liquid properties, pipeline layout, and operating operation conditions. The following specifically introduces the selection method of opening the pump in the stainless steel.
The nature of liquid, including liquid medium name, physical properties, chemical properties, and other properties, physical properties have temperature C density D, viscosity U, the diameter of solid particles and gas in the medium, which involves the system's raising, effective air erosion waste Types of quantity calculation and suitable pump: Chemical properties mainly refer to the chemical corrosion and toxicity of liquid media. It is an important basis for Changsha to use the pump material and the shaft seal type.
Traffic is one of the important performance data of pump selection. It is directly related to the production capacity and transportation capacity of the entire device. For example, the design institute can calculate the normally, minimum, and maximum traffic in the design of the design institute. When selecting the pump in stainless steel, the maximum flow is based on the normal flow. When there is no maximum traffic, it is usually 1.1 times the normal traffic as the maximum traffic.
The system required for the system is another important performance data for the selection of pumps. Generally, it is necessary to use a 5%-10%balance after the increase.
According to the installation, terrain conditions, water level conditions, and operation conditions of the device, select the pump of the horizontal, vertical, and other types (pipelines, diving, liquid, unlocking, self -suction, gear, etc.).
The pipe layout conditions of the device system refer to some data and pipeline specifications such as the lowest liquid surface of the liquid delivery of the liquid height, the lowest liquid surface of the side, and the length of the pipeline and its length, the materials, the size of the pipeline, the quantity, etc., etc. In order to carry out the computing of the computing and the amount of steam erosion.
Moved.
For the liquid pump (or density than 1000kg/m3) with a conveying viscosity greater than 20mm2/s, be sure to convert the performance curve of the viscosity (or under the density) with the water experiment pump characteristic curve. In particular, inhalation performance and input power Calculate or compare it carefully.
