How to choose the right pump model and specifications?

Pumps are an essential living tool for every family, and while most people do not recognize this, it is a fact. Many people know nothing about the pump. Below we will pump classification and model specifications to make a simple introduction. [Pump classification]: 1, according to the pump working principle and structure points: vane pumps, positive displacement pumps (and other types of pumps) such as: jet pump, air pump, electromagnetic pump, vacuum pump Pumps such as: centrifugal pump, vortex pump, mixed flow pump, axial flow pump, screw pump and other positive displacement pumps such as: reciprocating pump, rotor pump two reciprocating pump: electric pump, steam pump electric pump: plunger (piston) pump, diaphragm Pumps, metering pumps Rotor pumps: gear pumps, screw pumps, Roots pumps, vane pumps, etc. 2, according to the media points: clean water pump, sewage (dirt) pump, pump, corrosion pump, , Drum pumps, etc .; 3, from the use of installation on the points: pipe pumps, submersible pumps, submersible pumps, magnetic pumps and so on. After confirming the pump station's flowmeter and design head, you can use the relevant technical diagrams to determine the pump model and specifications, the method is as follows: First, the use of pump performance specifications Pumping pump plant in the product catalog provides this Kind of form, the performance of each model in the table has three lines of data, what kind of behavior? The general design flow and design head should be consistent with the values ​​listed in the middle of the performance table or close to each other and must fall within the upper and lower two lines as this range is a high efficiency area for pump operation, This type of pump is considered to meet the actual needs of the pump is selected. Second, the use of pump selection table Pump selection Based on the design of the lift and design flow to determine the selection table, the horizontal header to find the head of the design consistent with or close to the lift value; and then identify the vertical header Design flow rate consistent with or close to the value of flow, aspect intersects the small box, which marked the pump model, the initial selection of multi-stage pump. But sometimes there are two types of pumps to meet the design requirements, this time, the two pumps can be compared for the program, the technical and economic analysis, and then select one of the appropriate pump. This choice of pump method is relatively simple and fast. Third, the use of pump performance integrated spectrum Select pump type Centrifugal pump, axial pump, chemical pump, mixed-flow pump all the work area integrated drawing on the same map, which constitutes a comprehensive series of agricultural water pump spectrum, the Drawing more complex, but more convenient to use According to the design flow and design of the head to determine the type spectrum, the first in the ordinate on the design lift to find the head meet the requirements of the flow rate of several pumps, and then The abscissa design flow to determine which pump to choose. If the design flow is large, the single pump failed to meet the requirements, consider multi-machine operation, but should pay attention to try to use the same type of pump to facilitate the construction and installation, management and maintenance.

A threaded pipe is a pipe with a thread. They are often used in water gas pipes, small diameter water pipes, compressed air pipes and low pressure steam pipes. The pipe is connected to the pipe end with the thread. The thread can be coated with suitable adhesive (such as thick white paint, lead oxide glycerin adhesive, etc.) to ensure sealing.

There are mainly internal teeth, external teeth, live tube, elbow (elbow), three way pipe, four way pipe (crosshead) and reducer.Manufacturing standards:

GB/T 14383, ASME B16.11, BS 3799, MSS SP 83
