What is steam jet air ejector?
Steam ejectors use steam or gas instead of moving parts to compress a gas. In a jet or ejector, a relatively high-pressure gas, like steam or air, expands through a nozzle. The steam or air converts that pressure or potential energy to velocity or kinetic energy.
What is difference between ejector and eductor?
The ejectors are used to maintain a system vacuum in the upstream (Example maintaining the vacuum column pressure) whereas eductor’s main objective is to take out the volume of any fluid out of the system by maintaining a system pressure in the upstream.
Which steam is used in steam ejector?
4. In the steam ejector system, the steam (auxiliary steam) is passed through a nozzle and allowed to expand in one chamber. When the HP steam passes through a nozzle it expands in the chamber and creates vacuum in the chamber; this chamber is connected to the condenser so that the condenser vacuum is created.
What are the advantages of air ejection?
– No moving parts, therefore maintenance costs can be kept low. – Compact construction and easy installation. – Corrosion / erosion resistant as ejectors can be constructed from various materials so as to handle even corrosive fluids. – High vacuum capability at high suction loads.
How does a steam air ejector work?
What are the types of ejectors used in injection Mould?
The ejector pins are used in injection moulds to eject the plastic components from the moulds. There are 2 types 1) plane ejector pins 2) step ejector pins. The material used are En-31 and HDS( hot die steel).
What are the different types of ejection in injection Mould?
Ejection system types
- Pin ejection—Cylindrical pins eject the finished component.
- Sleeve ejection—This type of ejection is preferred for (and limited to) cylindrical cores, where the core is fixed in the bottom plate.
- Stripper plate ejection—This ejection is preferred for components with larger areas.
What is difference between ejector and injector?
As nouns the difference between ejector and injector is that ejector is one who, or that which, ejects or dispossesses while injector is any of various devices that are used to inject something.
How does an air eductor work?
An eductor, also known as a hootonanny or liquid jet pump, is a simple type of pump that uses the Venturi effect to pump or move a fluid (air, liquid or gas) in an enclosed line. This device has no moving parts, instead relying on only a motive fluid to operate.
What is an air ejector used for?
Air Ejectors are used to extend the operating range of Liquid Ring Vacuum Pumps, boosting performance. The inlet pressure of a Liquid Ring Pump is limited to approximately 30 mbar abs because of the vapour pressure of its seal liquid (usually water).
