Doppelkammer-DruckluftkolbenpumpeDescription:
Double chamber pneumatic piston pump

Die Doppelkammer-Druckluftkolbenpumpe (DDP) dient zum fördern von niedrig bis hochviskosen und pastösenProdukten, insbesondere Farben, Lacke und Beschichtungsmaterialien.The double-chamber pneumatic piston pump (DDP) is used to pump low to high viscosity and pasty products, especially paints, varnishes and coating materials.

Auf dem Markt gibt es eine Vielzahl von druckluftgetriebenen Förderpumpen, Rotationskolbenpumpen, Membranpumpen usw.There are a variety of pneumatic-driven feed pumps, rotary piston pumps, diaphragm pumps, etc. on the market.

Doch treten Schwierigkeiten insbesondere bei der wirtschaftlichen Förderung von lösemittelhaltigen (z.B. Xylol), hochviskosen und pastösen Produkten auf.However, difficulties arise, particularly in the economic extraction of solvent-containing (e.g. xylene), highly viscous and pasty products.

Die Pumpe besteht aus einem Arbeitszylinder und einem Kolben der in diesem Hubbewegungen ausführt. Am oberen und unteren Ende des Zylinders befindet sich jeweils ein T-Stück an dem jeweils die Druck und Saugseiten durch Rohrleitungen miteinander verbunden sind. Die DDP verfügt über ein großvolumiges Ansaugrohr. Bei jedem Kolbenhub öffnet sich, je nach Position des Kolbens, die untere, oder obere Ventilklappe auf der Ansaugseite. Auf der Druckseite öffnet die Ventilklappe auf Druck und schließt bei Sog.The pump consists of a working cylinder and a piston that performs stroke movements in it. At the top and bottom of the cylinder there is a T-piece to which the pressure and suction sides are connected by pipes. The DDP has a large-volume intake pipe. With each piston stroke, the lower or upper valve flap on the intake side opens, depending on the position of the piston. On the pressure side, the valve flap opens under pressure and closes under suction.

An der oberen und unteren Kammer des Arbeitszylinders befinden sich Entlüftungsventile die einen etwaigen Luftstau entgegenwirken.There are vent valves on the upper and lower chambers of the working cylinder which counteract any air build-up.

So ist gewährleistet das bei jedem Kolbenhub gefördert wird. Der Arbeitskolben besteht aus lösemittelbeständigen Viton.This ensures that fluid is pumped with each piston stroke. The working piston is made of solvent-resistant Viton.

Angetrieben wird die Pumpe durch einen mit Luftdruck arbeitenden Motor, der ebenfalls angetrieben durch einen Kolben axiale Hubbewegungen ausführt. Die beiden Kolbenführungsstangen des Antriebsmotors und des Arbeitszylinders werden mittels Gelenkverschraubung miteinander verbunden, so daß die Hubkraft des Antriebsmotors auf den Kolben im Arbeitszylinder der Pumpe übertragen wird. Mittels einer vorgeschalteten Wartungseinheit (Druckminderer), sowie einesRegulierventiles kann die Arbeitskraft und die Hubgeschwindigkeit herauf, oder herabgesetzt werden. Der Hubraum des Arbeitszylinders wird durch luftgesteuerte Endpunktschalter, die am Rahmen der Pumpe befestigt sind und die ihren Kontakt durch ein Bauteil an der Kolbenstange erhalten, sowie eines Zwei-Wege-Ventiles bestimmt.The pump is driven by a motor that works with air pressure, which also carries out axial stroke movements driven by a piston. The two piston guide rods of the drive motor and the working cylinder are connected to one another by means of a joint screw connection, so that the lifting force of the drive motor is transferred to the piston in the working cylinder of the pump. The working force and the stroke speed can be increased or decreased by means of an upstream maintenance unit (pressure reducer) and a regulating valve. The displacement of the working cylinder is determined by air-controlled end point switches that are attached to the frame of the pump and that receive their contact through a component on the piston rod, as well as a two-way valve.
