Submersible Pump Application The system consists of a submersible pump controlled by a Danfoss VLT AQUA Drive and a pressure transmitter. The transmitter gives a 4-20 mA feedback signal to the VLT AQUA Drive‚ which keeps a constant pressure by controlling the speed of the pump. To design a drive for a submersible pump application‚ there are a few important issues to take into consideration. Therefore the drive used must be chosen according to motor current. 1. The motor is a so called “Can motor”

Centrifugal Pump @ 1750 RPM · Figure 1 Head Pressure versus Flowrate · Figure 2 Ideal Power versus Head Pressure (H) · Sample Calculations · Raw Data Discussion of Experiment A centrifugal pump contains an impeller or set of vanes encased in housing. Energy is added to the fluid in the form of velocity and pressure as a result of the impeller turning. An engineer must determine the range of flow rates required when using a centrifugal pump. The centrifugal

James Dyson The Dyson G-force Vacuum Cleaner The first ever Dyson vacuum cleaner was invented by James Dyson in 1983. This design was said to be the largest innovative break through since the vacuum cleaner was first invented in the early 20th century. The reason for this newer‚ futuristic design was not only to improve the function of the vacuum cleaner but to also improve the look of the vacuum cleaner. James Dyson was annoyed with vacuum cleaners losing their suction power

consider a multiple pump system to meet the design requirements. Two typical options include parallel and series configurations of pumps. Specific performance criteria must be met when considering these options. Given a piping system which has a known design flow rate and head requirements‚ Qdes‚ hdes‚ the following pump selection criteria apply. Pumps in Parallel: Assuming that the pumps are identical‚ each pump must provide the following: Q(pump) = 0.5 Qdes h(pump) = hdes Pumps in Series: Assuming

Through common practise of Centrifugal pump operating characteristics is it possible to determine the optimum conditions of particular conditions. The results of typical characteristics are expressed on this work in terms of pump discharge pressure‚ pump efficiency‚ and power demand at various pump speeds of verses pump discharge.

This project is about fabrication of a dual powered outdoor vacuum cleaner‚ in which we will have a suction pump which will be run by a dc motor‚ the outlet of the pump will be connected to a bin which will hold the litter. The power to the dc motor will be provided by a battery‚ which will be charged by the solar panels mounted on top of the device. Provision is

Morality refers to the ability to do that‚ which is perceived right and universally acceptable. Morality plays a critical role in a person’s decision-making process. In Mark Twain’s story‚ “The Mysterious Stranger”‚ morality remains a common theme emphasized among the characters and forms
