Yuehai water Changping No.2 water plant uses kenfulai KPS series split double suction pumps

Introduction to Dongguan Changping Yuehai water Co., Ltd

Changping water supply company was founded in 1973 and located on the Hanxi river embankment of Changqiao. The original name was Changping water plant. It began to build Changping water plant in February 1973 and was completed and put into production in December 1973. At that time, it mainly supplied water to changpingxu residents and various units. With the development of Changping's economy and the increase of water supply population. In 1981, the second phase of Changping water plant was constructed; In 1984, the third phase of Changping water plant was built. After two expansions, the daily water supply reached 12000 tons / day.

With the needs of economic development, Changping's water supply business also developed rapidly. In July 1990, Changping water plant was renamed Changping Town water supply company. At this time, the Changping canal was seriously polluted, the water quality deteriorated, and it was no longer drinkable. The town government decided to invest 54 million yuan to build the Yuanjiang Yuan water plant, which covers an area of 80 mu and has a building area of 24000 square meters. It laid a water diversion pipeline to take water from Sima pumping station, the Dongshen water supply project supplying water to Hong Kong.

  In 1990, the first phase of the new Yuanjiang Yuan Water Plant was built, with a daily water supply capacity of 30,000 tons per day, and the water supply scope has begun to supply water to all rural areas in the town. In 1994, the second phase of the construction of Yuanjiang Yuanshui Plant reached 50,000 tons/day of daily water supply, and in 1998, the third phase of Yuanjiang Yuanshui Plant was built again with 50,000 tons/day water supply project. After the third phase of construction, the daily water supply of Changping Water Supply Company reached 130,000 tons/day. In November 2003, the construction of Changping No. 2 Water Plant began, covering an area of 400 acres, including 100 acres of plant buildings, 300 acres of reservoirs, a design water supply of 300,000 tons/day, and the first phase of the project of 150,000 tons/day, which was completed in July 2005. The second phase of the project is still under construction. The second water plant is a modern new water plant, equipped with a fully automatic central control system, which can basically realize unmanned automatic production. After the second water plant was put into operation, the production equipment of Changping Town Water Supply Company was continuously upgraded, and the service level and service quality were continuously improved. At the end of December 2007, it passed the ISO9001:2000 quality management system certification, realizing the institutionalization of water supply management, service standardization and procedure.

      In October 2011, it was wholly acquired by Guangdong Yuehai Water Affairs Co., Ltd., and changed to Dongguan Changping Yuehai Water Affairs Co., Ltd. on January 13, 2012.

原旧泵状况

The original pump adopts S-type split double suction pump, the motor protection level is IP23, and the traditional column pin coupling is adopted.

The pump unit runs noisily, vibrates, and the motor has poor splash resistance.

The protective ability of the coupling protective cover is weak, and there are potential safety hazards.

Technological transformation program

    1、Device updates

Replaced with a new energy-saving KPS horizontal split double suction pump, KPS series horizontal split double suction pump, is an energy-saving split double suction pump designed and manufactured by Guangdong Kenfulai Pump Industry Co., Ltd., with advanced hydraulic model, high fluid efficiency, advanced structure, advanced design of bearing components, and less noise and vibration of pump operation.

Product Name:Horizontal split double suction centrifugal pump

Model specifications: KPS35-300

Rated flow: 1300m3/h

Rated head: 42.5m

Rotational speed: 1480r/min

Supporting motor power: 200KW

2、Contract contracting method

  It is carried out on a general contracting basis. Huizhou Kenfulai Pump Sales Co., Ltd. is responsible for supply and on-site installation, and the on-site installation works include:
    (1) Dismantle the old water pump and motor;
    (2) Remove the old one-piece base;
    (3) According to the drawings of the new pump unit, excavate the concrete foundation and pour the new concrete foundation; Reserve secondary grouting holes.
    (4) Concrete curing, after the concrete has a certain strength, the equipment is hoisted;
    (5) Secondary grouting;
    (6) Pipeline connection; Welding of water inlet and outlet heads; cable wiring;
    (7) Precise adjustment of coupling alignment;
    (8) Debugging and trial operation.
    (9) Issue debugging and trial operation reports.

改造施工过程

    After Guangdong KENFLO Pump Industry Co., Ltd. completed the production of KPS35-300 pump unit, it carried out factory tests. The test results were qualified. Shipped to the site.

Huizhou KENFLO Pump Sales Co., Ltd. dispatched 4 construction personnel, including technicians, civil engineering, electrical and welders, to dismantle the old equipment and install new pump units on site.

After installation, precise adjustment of coupling alignment was carried out, followed by commissioning and trial operation. The relevant operating data was detected, and after data analysis, it was judged that the debugging was qualified and handed over to the user for normal use.

Concrete foundation

The picture above shows the poured concrete foundation, prepared on site according to the concrete ratio of C30 strength grade.

According to the size of the inlet and outlet pipes of the new pump, the center height of the inlet and outlet pipes, combined with the size and center height of the on-site pipes, the eccentric reducer pipe is tailored. The resistance loss to the water flow is smaller and the flow pattern is better.

From the incision, you can see that the welding quality is excellent, and the weld seam is full and beautiful.

The engineers of Huizhou KENFLO Pump Sales Co., Ltd. are centering the coupling and finding the right work.

After installation, commissioning and commissioning took place.

The operating current is normal.

Technicians from Huizhou KENFLO Pump Sales Co., Ltd. are measuring the vibration value of equipment operation. It can be seen that the vibration rates are 1.3/0.2/0.4 mm/s, which are far below the vibration values specified in the relevant pump standard manual. It shows that the pump unit runs smoothly and has low vibration. It also indicates that the bearings and rotor parts of the pump have a longer service life.

Users gave a thumbs up to Kenfula Pumps' products and installation services.
