What is a magnetically coupled pump?
Magnetically coupled pumps are a combination of conventional pump hydraulics with a permanent-magnetic drive system and a three-phase motor. This system uses the attraction and repulsion forces between permanent magnets in both coupling halves for contactless and slip-free torque transmission.
How does a magnetic coupling work?
In the simplest terms, magnetic couplings work using the fundamental concept that opposite magnetic poles attract. The attraction of the magnets transmits torque from one magnetized hub to another (from the driving member of the coupling to the driven member). Torque describes the force that rotates an object.
Can mag drive pump run dry?
Many Finish Thompson mag drive pump designs can run dry for hours without issue. In production applications where pumps are not under constant supervision, this ability to run dry can eliminate the risk of pump failure and the associated costs.
What is sealless pump?
A sealless mag drive pump is a conventional centrifugal pump without the dynamic seal that would normally be used to seal the pump shaft. This dynamic seal is replaced by a static containment shell to form a completely sealed liquid end or pressure boundary.
How does a magnetically coupled rodless cylinder work?
Magnetically Coupled Rodless Cylinders feature magnets on the carriage and piston that form a strong bond that holds them together. Our rodless actuators deliver space savings of nearly 50% in most models. When the cylinder is actuated, the piston and carriage move back and forth as one unit.
How does a magnetic piston work?
It works with the principle electromagnetic effect and attraction of magnetic force instead of using fossil fuels. It consists of, two permanent magnet and two electromagnets. Electromagnets are mounted on the cylinder head and the permanent magnets are mounted on the piston head.
Are mag drive pumps positive displacement?
When you have to pump hazardous or toxic fluids, Mag Drive positive displacement pumps are a practical solution for these seal-less pumping needs. Simply substitute the mag drive for one of Haight’s standard close-coupled mounting brackets and you are ready to tackle even the most demanding fluids.
What type of pump is a mag drive pump?
magnetically-driven chemical-process pump
Mag-drive pumps are a design of magnetically-driven chemical-process pump which eliminate the need for shaft sealing. This greatly reduces the initial cost of the pump as well as day-to-day operational costs as there aren’t any mechanical seals, seal-fluid pots, or cooling lines fitted.
How does a magnetic sealless pump work?
The principle of operation is very simple. The magnets in the outer and inner magnet rings are attracted to each other, so as the electric motor rotates, the outer ring and the inner ring rotate at the same speed, thus rotating the impeller and causing liquid to be pumped.
What is a canned pump?
A CANNED MOTOR PUMP IS COMPOSED OF: A TRADITIONAL CENTRIFUGAL HYDRAULIC & A SPECIAL SQUIRREL CAGE MOTOR CONNECTED IN A ONE PIECE ASSEMBLY. Canned motor pump schema. The Canned Motor Pump is composed of a traditional centrifugal hydraulic, connected to a special motor through a one piece assembly.
How does rodless cylinder work?
How does a rodless cylinder work? A piston moves within a cylinder bore, driven by compressed air, very much like a conventional profile or tie-rod cylinder; the difference is that motion is transmitted to outside through the body length, rather than by a piston rod through an end cap.
Why rodless cylinders are used?
Rodless cylinder differ from conventional cylinders and provide many advantages in comparison. Smaller footprint for similar stroke length making them ideal for applications with limited space. Ability to better support high loads and moment forces. With no rod, they eliminate the risk of rod bending and buckling.
Is a magnetic engine possible?
There have been many attempts to produce a motor that relies solely on permanent magnets to generate magnetic fields for both the stator and the rotor. And while this discovery could lead to the commercial creation of a permanent magnet motor, it hasn’t yet.
Is a canned pump a centrifugal pump?
The Canned Motor Pump is composed of a traditional centrifugal hydraulic, connected to a special motor through a one piece assembly. The stator is canned in the air gap, confining the liquid in the rotor chamber.
Why we use canned pump?
Advantages of canned motor pumps at a glance: Canned motor pumps meet the highest environmental protection standards. Double containment shell to the atmosphere. The motor housing and terminal box are designed as pressure-containing parts and as a second containment shell. Extremely low sound level.
What is a rodless actuator?
Actuators – Rodless Actuators. Rodless cylinders differ from a basic air cylinder in that no piston rod extends outside the cylinder body. Instead, the internal piston is connected to an external carriage, by means of a magnetic or mechanical coupling system.
What type of pump is canned pump?
CENTRIFUGAL HYDRAULIC
A CANNED MOTOR PUMP IS COMPOSED OF: A TRADITIONAL CENTRIFUGAL HYDRAULIC & A SPECIAL SQUIRREL CAGE MOTOR CONNECTED IN A ONE PIECE ASSEMBLY. The Canned Motor Pump is composed of a traditional centrifugal hydraulic, connected to a special motor through a one piece assembly.
Why efficiency of canned motor pump is less?
Answer: Typically, Canned Motor Pumps are selected due to the increased safety and reduced maintenance they offer. They are typically less efficient than air cooled motors because of the fluid inside the motor creating a larger “air gap” between the rotor and stator along with additional frictional drag on the rotor.
