Downhole motor is composed of five assemblies: by-pass valve, motor, anti-drop, cardan shaft and drive shaft.
Downhole motor is a kind of downhole dynamic drilling tool upon the power of drilling mud. Mud stream from the
outlet of mud pup flows through a by-pass valve into the motor. This stream produces pressure loss at both inlet and
outlet of the pump to push the rotor into ratating, and to transmit the torque and speed onto the bit. The downhole
motor property mainly depends upon its property parameters.

Ericsson has recently launched three services based on the Internet of Things. The service is mainly for communications and utility vendors. The IoT service includes a smart meter reading service called Smart Meteringasa Service (SMaaS), which is based on Ericsson's current technology. . Ericsson claims that its "smart meter reading service" can cover more than 42 million utility meters worldwide. This new and improved "smart meter reading service" will evolve into a more sophisticated and end-to-end application of automated management of smart meters and data collection. platform. When these data are accumulated to a certain level, telecom operators can deploy user and IoT data analytics covering the analysis engine in the user database to track and visualize more comprehensive configurations such as user behavior and data usage across the network. file.
In November 2015, Ericsson published a report entitled “Wisdom Citizens: How the Internet Helps People Make Smart Choices in Urban Lifeâ€. The report discusses how people inhabit more cities with more wisdom. wisdom. Michael Björn, Head of Research at Ericsson Consumer Research, said: “The public wants existing service providers to provide services through the Internet, such as expecting municipalities to provide ICT services related to transportation, public services, and water quality.â€
Ericsson and Verizon will work together to further develop and deploy low power wide area (LPWA) cellular networks for a wide variety of IoT applications. In order to promote the further development of smart cities, Ericsson's latest launch of network software 17A can handle the diversity of the IoT terminals and their connectivity requirements. The software includes key features that enable cellular networks to support smart cities, smart metering and smart agriculture. Ericsson introduced the industry's first complete LPWA cellular solution to accelerate the popularity of the Internet of Things, enabling operators to support a wide variety of Internet of Things applications in their various networks.
Ericsson develops IoT services to brighten smart city "torches"
[Chinese instrument network enterprise vane] Las Vegas CES2016 international consumer electronics show is hot, the Swedish technology giant Ericsson (Ericsson) exhibited this exhibition, and at the exhibition put forward the concept of the Internet of things. In the Internet of Things, Ericsson is more inclined to adopt a more tangible method and strategy to explain more essential data and related technologies and light up the torch of smart cities.
