Circular gear pump selection precautions

Circular arc gear pump in today's industrial, chemical, scientific research and other fields have a very important value, but it is also a relatively special equipment, its work not only to consider its own functional characteristics, At the same time also pay attention to arc gear pump work environment and work intensity, in short, arc gear pump selection is not just a few words of sales staff can be summarized. Circular gear pump selection precautions Circular gear pump selection Note: 1, the flow rate is one of the important performance data gear pump gear selection, which is directly related to the entire plant's production capacity and delivery capacity. Cycloid gear pump election to the maximum flow as the basis, taking into account the normal flow, in the absence of maximum flow, it is usually desirable 1.1 times the normal flow as the maximum flow. General industrial pumps in the process can ignore the leakage in the pipeline system, but must consider the impact of process changes on the flow. 2, the pressure required to install the system is another important performance data selected gear pump, the general need to enlarge the 5% -10% margin pressure to choose cycloid gear pump model. This includes: sump pressure, sump pressure, pressure drop in the piping system. 3, arc gear pump system devices by the pipeline layout conditions refers to the height of the liquid, liquid transport distance, the direction of liquid transport. For system pressure calculation and power check. Pipeline system data such as: diameter, length, type and number of pipe fittings, oil sump to the pressure tank geometry and so on. 4, the liquid properties and the physical, chemical and other properties of the liquid medium, the physical properties of the temperature c density d, viscosity u, medium particle diameter and gas content, etc., which involves the system pressure, the required power calculation And the type of suitable pump: chemical properties, mainly refers to the liquid medium chemical corrosion and toxicity, is the choice of gear pump material and choose which type of shaft seal an important basis. Through the above four points of analysis, we can find arc gear pump selection considerations should have what content, in today's rapid technological development of these times, the use of many tools may have been very simplified, but for some devices to Said that still need to continue in the traditional way. Just like the use of arc gear pump, we absolutely can not forget arc gear pump selection considerations. This article is copyrighted industry interconnect (Xiamen) Co., Ltd.
