New app simplifies pump operation

Wednesday, July 18th, 2018 von admin

This new KSB app called ‘FlowManager’ can be used to operate and configure the PumpDrive 2 and PumpDrive 2 Eco variable speed systems. It can also be used to adjust the fixed speed of MyFlow Drive to the optimum operating point. The new KSB FlowManager app features all of the familiar basic functions from previous versions of the MyPump Drive app and supports both IOS and Android devices. It is available for download from the iTunes Store and Google Play Store free of charge.

The app’s main functions can be summarised under the terms operation and monitoring.

Siemens extends synchronous-reluctance drive systems

Tuesday, April 24th, 2018 von admin

Siemens is extending its portfolio of Simotics synchronous-reluctance motors to include the two new shaft heights, AH90 and AH225. With these new additions, the company is addressing calls from renowned manufacturers of pumps.

The motors are available in a power range of 0.55 to 45 kW, and now also with rated speeds of 1,500 and 3,000 min1. In conjunction with the recently launched Sinamics Reluctance Control License, precise encoderless closed-loop torque control is possible down to a standstill. The license enables field-oriented (vector) closed-loop control even when at a standstill – reliably eliminating the possibility of the synchronous motor “stalling” at any time even if the load inertia is not known.

Converter handling simplified by new module for wireless commissioning

Tuesday, April 17th, 2018 von admin

The new Sinamics G120 Smart Access Module enables the wireless connection of mobile devices such as tablets, smartphones or laptops over WiFi to the Sinamics G120, Sinamics G120C and Sinamics G120P pump converter series, making for considerably simpler converter handling.

The module is set up in a few simple steps using a conventional web browser and any standard operating system. The web server functionality eliminates the need to download any additional software. With its intuitively structured user interface and menu guidance, the module offers outstanding user convenience.

New plunger pump head reaches up to more than 1,000 bar

Friday, April 13th, 2018 von admin

The plunger pumps feature an integrated gear, which enables very compact construction with maximum efficiency.

For the purpose of upgrading a cracker in a Chinese refinery a total of five plunger pump skids should be brought into operation by Lewa. Those in charge of the project opted for three triplex and two quintuplex plunger pumps in accordance with the API 674 standard. These pumps are equipped with the new KMC-L pump head with reduced clearance volume. This head consists of a single forging: The suction manifold is integrated as a result, allowing for a reduction in the sealing surface and thus in any potential leak points. An additional advantage is the fact that the suction side can be designed to handle backpressure, eliminating the need for a safety valve in the suction line. The new design makes it possible to realize pressures up to 1,075 bar. All pumps in use have been produced in Germany and mounted to a complete system in the Chinese plant.

These plunger pumps have a drive output of 260 kW and a flow rate of 25 m3/h. The suction pressure loss of the pump heads is very low, therefore a low suction pressure is needed and it is often possible to operate without a booster pump.

Efficiency comparison pumping system

Thursday, January 25th, 2018 von admin

An increasing number of pumps are now being run using speed control in order to be able to define the dynamic volume flow. The pump’s quadratic characteristic causes the motor load to decrease rapidly at lower speeds, which results in the level of efficiency decreasing significantly. Using the diagrams, it can be seen that the ideal workload for the existing asynchronous motor is not reached, due to operation at partial loads (approx. 30%) and speeds (75%).

If the pump is then equipped with a PMSM motor that has an extended efficiency range including partial load operation, the level of efficiency can be increased by approx. 12% in this example and savings of more than EUR 250 per pump per year can be achieved (depending on the number of hours‘ operation per year).

Green pumps for a green stadium

Tuesday, January 16th, 2018 von admin

Croke Park is a major Gaelic Athletic Association (GAA) sports venue located in Dublin that hosts events for a number of sports. Croke Park has been at the heart of Irish sporting life for over a hundred years, it is not only an iconic landmark but also the third largest stadium in Europe.

Since 1884 the site has been used primarily by the GAA to host Gaelic games, most notably the annual All-Ireland finals in Gaelic Football and Hurling. In honour of Archbishop Thomas Croke, one of the first GAA’s first patrons, the stadium was renamed to Croke Park.

Sulzer doubles capacity of high voltage testing to improve repair times

Thursday, January 11th, 2018 von admin

Performance testing of high voltage motors and generators is usually carried out to determine benchmark data following a major repair. However, increasingly, customers are requiring this information as part of a problem diagnosis or to verify performance figures for a component when its essential data has been lost. To keep up with growing demand, Sulzer has made a major investment at its Falkirk Service Center (Scotland) that will enable the test-bed load capacity to be doubled.

Until now, the Falkirk site has used a 1,250 kVA diesel generator that operates through two step-up transformers to provide 3.3 – 11 kV via high voltage switchgear to the test cell. This setup ensures a reliable power source for testing that is not affected by local demand on the power grid. The new investment will add a 2,000 kVA and a 700 kVA generator to the site that will be synchronized through a 4000A LV switchboard, as well as a new 2,500 kVA transformer, that will double the capacity of the test bed.
