A few days ago, Dagang Zhongcheng Machinery Manufacturing Co., Ltd. manufactured and installed 1000 cubic meters of displacement and 2000 meters of lift. The first electric pump unit with the largest displacement and the highest lift in China was successfully put into operation in the NP1-P4 well of Qiandongnanpu Oilfield. This marks the leading level of submersible electric pump manufacturing in Dagang Zhongcheng Machinery Manufacturing Co., Ltd.

The NP1-P4 well in the Qiandongnanpu oilfield is an oriented horizontal well. The well is the longest well in the domestic level after the NP1-P1 well and the NP1-P2 well. According to the NP1-P4 well data, Jidong Oilfield decided to adjust the submersible pump type from 800 cubic meters to 1,500 meters to 1000 cubic meters and 2000 meters, and required Dagang Zhongcheng Machinery Manufacturing Co. to complete the submersible pump within 15 days. The unit is equipped and tested, and the relevant ground equipment is equipped.

After receiving this urgent task, Dagang Zhongcheng Machinery Manufacturing Co., Ltd. designed the unit supporting plan in the shortest time. In order to achieve high quality of the unit, the company organized technical seminars for many times, and technicians were on site to guide and ensure the smooth implementation of the design.

On April 15, the electric pump unit was successfully delivered to the well site of Jidong Oilfield. In order to ensure the success of the downhole, the on-site service personnel of Dagang Zhongcheng Company will accurately enter the motor, protector, separator and centrifugal pump into the well according to the process requirements. After 10 hours of continuous fighting, the NP1-P4 well test was successfully put into production.

All reducers, either eccentric or concentric, decreasethe effective size of the pipe. With smaller crosssectional area there is increased frictional resistanceto the flowing material and an increase systempressure.The eccentric reducer has the reducing outlet end off center. It will line up straight with one side of the inlet but not with the other outlet. This reducer is harder to
manufacture than the Concentric Reducer and costs more. One advantage over the concentric reducer is that can
be hung or suspended flush against a flat ceilling or wall. This lends greater support to the piping system and many times reduces the required space. When used in horizontal piping systems with the straight
side up, it acts as a trap for foreign material. When installed straight side down, it prevents trapping of foreign material.
The concentric reducer is made with both inlet and outlet on a common center line. This reducer is less ostly t manufacture than the eccentric typeand is adaptable to most piping installations.
