The protector is set between separator or intake and motor in ESP unit. Except for the connection function, the following is the main feature;
1. Seal the power output of the motor to prevent well fluid from entering into the motor;
2. Balance the pressure between the tube annular room and the inside of motor.
3. Balance the axial force of the shaft and separator shaft.
4. Meet the need of expanding and contracting in motor.
Our company can offer protector and rubber bag protector according to the requirement of customers. We can also equip different anti-temperature protector with the different pump.

Dividing 6 efforts to develop the power industry to take a new road to industrialization. In order to build a well-off society in an all-round way, the paper strives to improve the practicality of this paper. This paper introduces how to improve the starting mode of a large synchronous motor generator set 15MW*60MVA synchronous motor-generator set for Transformer test, and calculates the improved method, and summarizes the improved experience.
Associate Professor and Associate Professor of Engineering Electromagnetic Field and New Technology Research Institute. Address: Shenyang Motor CAD Software Package Yuan Hong As everyone knows, WindowS98 is the most widely used operating system for personal computers. VisualBasic has become a popular programming language for Windows.
Based on VisualBasic, the motor CAD software is developed to have a series of advantages such as friendly interface, simple operation and convenient use, which will be well received by the majority of motor design users. The author developed a CAD software package for small and medium-sized three-phase asynchronous motors, large three-phase asynchronous motors, single-phase asynchronous motors and large-scale DC motors based on VisualBasic6.0, which satisfies the needs of users.
This paper takes the development of large-scale three-phase asynchronous motor CAD software as an example, introduces the method and skill of developing motor CAD software package with VisualBasic6.0, including the overall structure and function design of motor CAD software package, and the VisualBasic control and window needed to develop motor CAD software. Programming techniques such as interface design.
The motor CAD software package popular by users must have the following characteristics: 1 can be used in Windows environment; 2 user-friendly interface, easy to use; 3 in line with the habit of motor design users, that is, input or modify design data is intuitive and convenient, necessary graphics Display, electromagnetic calculation is fast and accurate, and the calculation result can display output and print output. According to the above requirements, the CAD software of the large three-phase asynchronous motor designed includes “input data†and “electromagnetic calculationâ€, and each menu can be executed to perform the corresponding functions.
In the 6.0 environment, create a "project" called dxACmotor.vbp, which contains 4 windows "process" and a main program module "process".
VB provides a richer control for package developers. The choice of controls varies from person to person. The controls used in this article mainly include: form control form, mark control Label, text box control TextBox, graphic box control PictureBox, combination Box controls such as ComboBox.
Associate Dean of the School of Electrical Engineering, Professor. Mainly engaged in research work in the field of electrical machinery and its control. Address: No. 58 Xinghua Street, Tiexi District, Shenyang City, the application of the postal classic design mode in the design of power system wiring diagram production software Zeng Jianbin Xie Dexin designed reusable object-oriented software has certain difficulty. Because designers must find related objects, classify them at the appropriate granularity, and then define the interface and inheritance hierarchy of the class to establish the basic relationship between the objects. The design should be specific to the specific problem, and should be sufficiently versatile for future problems and needs, and care should be taken to avoid repetitive design or to minimize repetitive design. The use of sophisticated design patterns in software design can effectively avoid or reduce repetitive design.
