Construction and installation
FAQ
01.What is a pipeline pump? What are its structural features?
02.What are the different types of pipe pumps and what are their common features? And what are their respective applications?
②, The IRG type single-stage single-suction hot water pipeline pump is used for increasing pressure and circulating the hot water from boilers in industries such as metallurgy, chemical engineering, textile, wood processing, papermaking, as well as in departments like hotels, bathrooms, and guesthouses. The maximum operating temperature is ≤ 120℃.
③, The IHG single-stage single-suction chemical pipeline pump is used for transporting chemically corrosive liquids in industries such as textiles, petroleum, chemical engineering, medicine, hygiene, food, and oil refining. The operating temperature is ≤ 100℃. It is an ideal product for replacing conventional chemical pumps.
④, YG type single-stage single-suction pipe oil pump. It is an ideal product for conventional oil pumps. It is suitable for oil depots, refineries, chemical industries, and power departments of enterprises and institutions for transporting oil and flammable, explosive liquids. The operating temperature should be below 120℃.
5. The GRG, GHG, and GYG single-stage single-suction high-temperature pipeline pumps are designed by adding a water-cooling cooling device to the ordinary type. The operating temperature is ≤ 185℃. Their application scope is similar to that of the ordinary type.
GRG is a high-temperature hot water pump, GHG is a high-temperature chemical pipeline pump, and GYG is a high-temperature pipeline oil pump.
03.The basic parameters of the pump?
04.What is flow? Which letter is used to represent it? How many units of measurement are there? How is it converted? How is it converted into weight and what is the formula?
Measurement units: cubic meters per hour (m3/h), liters per minute (L/min), liters per second (L/s)
1 liter per second = 3.6 cubic meters per hour = 0.06 cubic meters per minute = 60 liters per minute
G = Qr G represents weight r represents the specific gravity of the liquid
Example: The flow rate of a certain pump is 50 m³/h. What is the weight per hour when pumping water? The specific gravity of water r is 1000 kilograms/cubic meter (or 1 g/cm³).
Solution: G = Qr = 50 × 1000 (m³/h. kg/m³) = 50000 kg/h = 50 T/h
05.What is the efficiency of a pump? How is the formula?
Effective power refers to the pump's head × flow rate × specific gravity (weight flow rate) Ne = rQH. The unit is kilowatts.
1 kilowatt = 102 kilograms meters per second 1 kilowatt = 75/102 horsepower
Shaft power and centrifugal pump power refer to the power transmitted from the prime mover to the pump, that is, the input power. The unit is kilowatts.
n = Ne / N = rQH / 102N where r is tons per cubic meter, Q is liters per second, and H is meters.
n = Ne / N = rQH / (102 × 3.6N) where r is tons per cubic meter, Q is cubic meters per hour, and H is meters.
06.What is the characteristic curve of a pump? What aspects does it include? What is its function?
The characteristic curves include: flow-head curve (Q-H), flow-power curve (Q-N), flow-efficiency curve (Q-η), and flow-allowable suction head rise curve (Q-(NPSH)r).
The function of the performance curve is that for any flow point of the pump, a set of corresponding values of head, power, efficiency and cavitation margin can be found on the curve. This set of parameters is called the working state, which is abbreviated as working condition or working point. The working condition with high efficiency is called the optimal working condition point, and the optimal working condition point is generally the design working condition point. Generally, the rated parameters of a centrifugal pump, that is, the design working condition point and the optimal working condition point, coincide or are very close. In practice, operating within the high-efficiency range can achieve energy saving while ensuring the normal operation of the pump. Therefore, understanding the performance parameters of the pump is quite important.
The selection of materials for the pipeline pump is rigorous. The pump body part is made of high-quality cast iron, stainless steel and other materials. The sealing and motor parts are all from brand suppliers with guaranteed quality. During the selection process, the appropriate material for the pump body of the pipeline pump can be chosen according to the liquid used. According to the usage environment, various standard motors of different specifications such as ordinary motors, explosion-proof motors, outdoor motors, and variable frequency motors can be selected. The pipeline pump can be installed and used independently, or it can be installed in series or in parallel according to the performance requirements of actual use. To adapt to the medium temperature, there are also high-temperature or low-temperature types available for selection, suitable for industries such as petroleum, chemical engineering, metallurgy, electricity, papermaking, food and pharmaceuticals, and synthetic fibers. Currently, pipeline pumps are widely used in various industrial and urban water supply systems, such as boosting water supply for high-rise buildings, garden sprinkling, fire boosting, long-distance transportation, heating and ventilation and refrigeration circulation, bathrooms, etc.
