State Of The Art Pump Testing

Vogelsang & Benning for Speck pumps developed innovative test Bochum, January 2014 quality assurance of pumps is essential, the requirements for manufacturers up. Research on efficiency and energy efficiency classes are in accordance with ISO 9906 and EN 60030-2. These are no easy homework even for a renowned company such as Bacon from Roth. The manufacturer produces annually about 250,000 pumps. Now, to meet the high demands, he invested in a new test for centrifugal and side channel pumps.

While Bacon was once more on the expertise of Vogelsang & Benning. The test is used for investigations on dry, centrifugal pumps. These come as a separate pump or as a complete unit with its own electric drive on the test bench. The supply of units secures a variable AC supply. Thus, all occurring worldwide voltage variants can be reproduce. There are three test places for storing QH curve.

The open tank system in stainless steel features adjustable suction lines. A Another Benchtop is used perform QH – and NPSH measurements. This is a closed, fixed to the vacuum tank system with discharge pipe swivel joints. Lowering the suction side pressure is accomplished by a vacuum pump. To fix and to drive the pump three flexible test cars are part of the system. Each has a height-adjustable test motor as well as a height-adjustable mounting plate. The test engines with 90, 30 and 5.5 kW have different graded torque measuring shafts for capturing the power of the pumps input. Each drive has an own frequency converter to the setting of the variable speed from 0 up to 3,000 min-1. Structure and functioning of the system it is controlled by a central control computer. A PLC is under besieged this, which is responsible for the control of adjustment and control devices, drive supply and all other digital control commands. A frequency inverter with downstream transformers ensures the electrical supply. The sensors are equipped mostly with PROFIBUS interfaces. The further delivery includes sensors and transducers, switchboards, computer technology and connection and system cabinets. The test runs can be carried out either manually or automatically. The modular design, developed by Vogelsang & Benning, testing / evaluation software allows free configuring of a test plan. Thus, the extent of the tests can be set according to the operator, and depending on the respective devices and requirements can. The measured values are stored in a central SQL database and provided the customer thus companywide. About vajra & Benning now 30 years, Vogelsang & Benning for the pump industry is an established and reliable partner. Also in other industrial sectors, the Bochum company has made a name.
