Application

Vacuum pumps for textile machines

In textile machines vacuum draws in and guides threads, extracts edge trims, lint and dirt on weaving and knitting machines, and draws the air out of the yarn during steaming. Elmo Rietschle names yarn handling and edge extraction on air-jet weaving machines and dirt extraction on knitting machines with side channel blowers, Atlas Copco yarn processing for its DB side channel blowers. Below you can see how the application works, what vacuum the manufacturers name and which of their series are intended for it – 115 models from 2 manufacturers.

Operating principle

How it works: Textile machines

The drawing shows the basic principle in section. The systems and pumps of the individual manufacturers differ in detail.

  1. SuctionThe suction nozzle draws in the thread and guides it – on air-jet weaving machines Elmo Rietschle calls this yarn handling.
  2. HoldingThe air flow holds the thread on its path; at the edge and at the needles of the knitting machine it carries lint and dirt along.
  3. RemovalThe air flows through the filter to the side channel blower, which releases it again oil-free; fibres and dirt stay in the filter.

Vacuum and sizing

Textile machines: how much vacuum is needed

What the manufacturers say about pressure, pumping speed and sizing.

What vacuum

For textile machines Elmo Rietschle and Atlas Copco name side channel blowers; they work with a lot of air at low negative pressure. The requirement depends on the number of nozzles and extraction points.

What determines the sizing

Elmo Rietschle distinguishes yarn handling and edge extraction on air-jet weaving machines from dirt extraction on circular and flat knitting machines (G-BH1 to G-BH100); Elmo Rietschle names the steam treatment of yarn without a series. Atlas Copco lists yarn processing for DB without further details.

Frequently asked questions

Textile machines: frequently asked questions

What is vacuum used for in textile machines?

Elmo Rietschle names three tasks: yarn handling and edge extraction on air-jet weaving machines, dirt extraction on circular and flat knitting machines, and the steam treatment of yarn. Atlas Copco lists yarn processing for its side channel blowers.

Which vacuum pump for textile machines?

Both manufacturers name side channel blowers: Elmo Rietschle the G-BH1, G-BH2, G-BH7, G-BH9 and G-BH100 series for dirt extraction on knitting machines, Atlas Copco DBS, DBSt, DBD and DBDt for yarn processing. Elmo Rietschle lists yarn handling on weaving machines and steam treatment without a series.

Which blower for extraction on knitting machines?

For circular and flat knitting machines Elmo Rietschle names dirt extraction with G-BH1 to G-BH100 side channel blowers.

Which vacuum pump for air-jet weaving machines?

For air-jet weaving machines Elmo Rietschle names yarn handling and edge extraction, but assigns no series. For yarn processing Atlas Copco lists the DB side channel blowers.

How much vacuum does a textile machine need?

The side channel blowers named work with low negative pressure and high air flow; the requirement depends on the number of nozzles and extraction points.

Why side channel blowers in textile machines?

Both manufacturers name side channel blowers for textile machines. They deliver a lot of air at low negative pressure and run without oil; thread suction and extraction need air flow, not a low ultimate pressure.

Oil-free or oil-lubricated for textile machines?

Oil-free: for textile machines Elmo Rietschle and Atlas Copco name side channel blowers (G-BH, DB), which run dry.

Which vacuum pump for steaming yarn?

Elmo Rietschle names the steam treatment of yarn as an application, without describing it or assigning a series. During steaming the air is drawn out of the yarn package so that the steam can penetrate; which pump fits depends on the steamer.

A single pump or a central vacuum system?

A central system in a room of its own keeps noise and heat away from production and matches its output to the demand. Central vacuum systems are planned and built by Eugen Theis Vakuum, a company of the Ehrler & Beck group – more under Central Vacuum.

Does Ehrler & Beck also supply spare parts and service?

Yes. Ehrler & Beck offers original spare parts and accessories as well as maintenance and repair.
