The Deep suction, suction far - Centrifugal Pumps PDF Print E-mail
Thursday, 18 May 2017 10:08

1- Origin of research and manufacture of the deep suction, suction far - centrifugal pumps:

Since 2000, the Ministry of Agriculture and Rural Development has assigned the Institute to carry out many research projects and projects for manufacturing deep suction and suction far centrifugal pumps. installed along riverside and coastal areas to serve agricultural anti-drought pumps. The outstanding advantage of deep suction and suction far centrifugal pumps is that the pump has a large vacuum column HCK = 7.0 - 8.0m that conventional centrifugal pumps only reach a vacuum column lower than HCK = 4.0. - 6.0 m.

Due to the large vacuum column, the suction height of the pump is larger than conventional pumps from 2.0 to 3.0 m, saving the cost of excavating the soil and lowering the elevation of the machine and facilitating the operation management conviniently. The IPM's deep suction pump centrifugal products have H = 10-150 m, Q = 50-5000 m3 / h, suction up to 7m, pushing up to 5000m. Pumps have been installed in 20 mountainous midland provinces since 2001 to now work stably for good production. Such as Bac Giang, Thai Nguyen, Bac Kan, Lang Son, Hoa Binh, Phu Tho, Vinh Phuc, Ninh Binh, Thanh Hoa, Binh Dinh, ...

Due to its effective application, the deep suction centrifugal pump has won 2 domestic and international science awards. Approved by the Ministry of Agriculture for broad adoption across the country

2- Technical advantages and efficiency of using deep suction centrifugal pumps

1- Having the same structure as normal centrifugal pump, but deep suction centrifugal pump has the ability to create large vacuum column [HCK] = 7- 8m, but ordinary centrifugal pump only reaches [HCK] = 4- 6m.

- Deep suction centrifugal pump manufactured by the IPM reaches H = 10-150 m, capacity Q = 50-5000 m3 / h, suction up to 7m deep, pushing up to 5000m, motor power for pulling pumps N = 7- 160 kw.

2- Having suction height to install pump reaches HHUT = 7m, but the normal centrifugal pump only allows installation at low terrain suction height: HHUT  4.5 m approximately.

Very suitable for riverside pumping stations, where the suction height is large oscilate..

3- It is possible to pump deeply against drought in the dry season, pump less to be suspended, improve the ability to fight against drought when the river water is lowered.

4- Resistant to flooding pumps in the rainy season. The pump is installed at a height of 2-3m higher than conventional pump, so it limits the flooding of the pump due to high rise of water river in the rainy season.

5- The cost of construction of the whole project is low, because the deep suction centrifugal pump allows installation at a high suction height, the structure of the station is simpler, reducing the cost of digging and lowering the project, reduce material costs, quick construction.

6- High durability, stability and convenient operation management. less damage occurs, ensuring timely pumping of water for crops and increased crop yields.

7- Being able to actively supply equipment and accessories in time for production, due to pumps manufactured in Vietnam and mastered technology.

8. There are advantages of increasing capacity, increasing efficiency when installing deep suction pumps in the field where there are low suction columns.

9. Being able to suck up to 100-200m in coastal areas to serve vegetable cultivation and shrimp farming on sandy beaches.

10- There is a topography that applies the installation of water pumps in all three regions: Delta, Midland and Mountainous Region with the height of the high and low suction varying from 1-7m.

11- Able to pump sediment in suction of foundation pit and pump animal waste.

12 Economic efficiency to develop agricultural economy and rural mountainous.

3 - Fields of application of deep suction centrifugal pumps:

- 7m deep suction pump to combat agricultural drought,

- Suction pump up to 100m away for planting clean vegetables along river banks,

- Suction pump 200m far away for aquaculture in coastal areas,

- Deep suction pump of foundation pit of construction works

- Pumping animal waste waste pumps.

- Pump of daily-life water supply at urban focal stations

4 - List of deep suction centrifugal pumps to combat drought, offshore suction and foundation pit works
