Problematic solids such as sanitary towels, plastic baggage, textiles and wood are being discovered increasingly more typically in wastewater. Pumping and sewage remedy crops are subsequently more and more reaching their limits; items get clogged up and break down.
In occasions when low lifecycle prices are enjoying an ever extra important position, HOMA Pumpenfabrik presents an power environment friendly and reliable answer for areas the place a high delivery head is required, however at the identical time, a various range of solids is anticipated: the Alligator chopper pump series. The newly developed OC impeller of the Alligator sequence permits effective operation via a powerful cutter system. Thanks to using extremely durable chilled chrome cast iron, the primary components which are topic to essentially the most stress perform reliably even with abrasive substances similar to sand. HOMA will be presenting the model new Alligator chopper pumps for the first time at IFAT 2022 in Munich.
“The lowest attainable lifecycle costs are becoming increasingly necessary in water and wastewater applications,” explains Konstantin Pörsch, Project Manager within the Design & Development division at HOMA Pumpenfabrik GmbH. “There is a growing demand for vitality saving and dependable pumps that reach excessive supply heads with nice effectivity.” With เครื่องมือใช้วัดความดัน , which will also be out there as an explosion-proof model, HOMA has developed a particularly environment friendly response to this demand.
Cutter system shreds all solids with excessive efficiency
“Our aim was to achieve excessive delivery pressures in the medium flow fee vary,” stories Konstantin Pörsch. Without forfeiting pump price, the improved efficiency meant that a smaller, cheaper and extra power saving motor than in other pumps in the same working vary was enough. To obtain this, HOMA developed a model new cutter system that effectively shreds and removes giant quantities of numerous solids corresponding to tear-resistant hygiene wipes, plastic baggage and wooden, which also get into the wastewater by way of surface water. The specially designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the wear and tear plate, which can also be equipped with its own cutter. This design permits the two central parts to work together to catch solids, break them down and in the end take away them from the suction area by way of built-in grooves in the put on plate.
To enable greater efficiency with out compromising on chopping efficiency, the blades of the impeller also curve strongly backwards. As a end result, within the 50 Hz version, a flow fee of up to one hundred thirty m³/h and a supply head of up to 57 m could be achieved with energy consumption of 5 to 12 kW. In the 60 Hz model, with power consumption of eight to 20 kW, a circulate fee of as much as 140 m³/h and a supply head of as a lot as 82 m are possible. The suction cover mounted on the pump housing may additionally be used to adjust the cutting hole between the impeller and the wear plate with the aid of six set screws. “The strength of our new Alligator series, which is available for wet properly installation in addition to dry installation, is its great effectivity and efficient cutter system, coupled with an extended service life,” provides Konstantin Pörsch.
เกจวัดแรงดันลมคือ to wear-resistant design
In order to achieve not only the finest possible efficiency values in the operating range required for these sorts of wastewater purposes, but additionally to scale back lifecycle prices overall, HOMA attaches great importance to low-maintenance operation along with effectivity. The impeller and put on plate, which are the components topic to essentially the most stress, are manufactured from extraordinarily sturdy chilled chrome cast iron, which withstands even abrasive substances such as sand in the pumped medium. In addition, the hydraulics have been optimally designed for the working vary using computational fluid dynamics (CFD) to extend efficiency and to get rid of any risk of solids increase, which might negatively impact performance and lead to pricey pump failures. “With the newly developed cutter system, the Alligator pumps can effectively break down all solids in the waste water and transport them away, saving each power and upkeep costs because of their excessive efficiency and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them significantly appropriate for waste water functions that require high supply strain, however on the identical time have to deal with many various sorts of solids.”
HOMA shall be presenting the new Alligator chopper pump sequence for the first time at IFAT 2022 in Munich. This and other improvements, corresponding to the upkeep slide with sliding motor mount, will be defined and demonstrated by the HOMA gross sales team in Hall B1 at Stand 429/528.
