Ejector pumps are used for drawing-in (pumping), thrusting and transport of all types of liquids, emulsions and suspensions. Pumped and drawn-in liquids can contain gases (air, methane, carbon dioxide etc) and un-dissolved solid grains and pieces of material of different origin and size. They are used for performing a series of different operations in many […]
One of the most significant tasks of centrifugal pumps is operation in wide pressure and flow ranges. Regulation of pressure and flow is performed only in regions defined by Q-H pump curves. The classical method of exchange of working points of centrifugal pumps is performed by muffling. Muffling is also used for pump protection from […]
Ejector mixers are used for mixing liquids, emulsions and suspensions with different physical and chemical compositions. Depending on the fluid being mixed they can be divided into: ejector hydro mixers (liquid-liquid) ejector gas hydro mixers (gas-liquid) ejector vapor hydro mixers (vapor-liquid) Ejector mixers can be used for mixing gases and vapor (see more detailed data […]
Ejector vapor heater (vapor-liquid) Ejector hydro heater (liquid-liquid) Ejector heaters are used for fast and efficient heating with 100% utilization of the input heat energy. For drive ejector heaters use the energy of input fluids. Fluid with a higher input pressure is called the driving fluid while the fluid with the lower input pressure is […]
Cooling in vacuum: Development of cooling techniques in vacuum is growing rapidly. Liquids, emulsions and suspensions cool by themselves without the use of other cooling liquids. One of the methods of fast cooling in vacuum is using ejector cooling devices, i.e. ejector vacuum pumps (see Ejector vacuum pumps). In ejector cooling devices vacuum is provided […]
Depending on the driving fluid ejector ventilators can be: ejector gas ventilators (gas-gas); ejector vapor ventilators (vapor-gas); ejector hydro ventilators (liquid-gas). All ejector ventilators use energy of the input fluid for drive: gas (most often air); liquid (most often water) and vapor (most often water vapor). The operating principle of all ejectors is to transform […]
Depending on the type of driving fluid ejector compressors are divided into: Ejector hydro compressors Ejector gas compressors Ejector vapor compressors Operating principle: All ejector compressors operate on the principle of using high pressure energy of the driving fluid for pumping in and compressing pumped gases. The pressure of the fluid mixture at the ejector […]
Hydro-transport is transport of a hydro-mixture consisting of a liquid (most often water) and small undissolved particles. Besides other devices, ejectors are used for hydro-mixture transport. Ejectors can be used for transport of loose solid materials, whose particle size can be larger than 25 mm. They are used for flows up to several 100 m3/h, […]
Pneumatic transport includes transport of powder and grain-like materials with air or another gas. Ejectors together with other devices are used for pneumatic transport. Besides transport of powder, grain-like and other loose materials ejector pneumatic transport can be used for liquid transport. Taken in fluids of powder, grain-like or other loose materials can consists of […]
According to their construction and operation method ejector heat pumps represent a specific type of heat pumps. Their construction is simple. They have no mobile parts. They do not use cooling fluids and use water vapor or cold water as driving fluids. Using these pumps a large amount of heat energy present in waste water, […]
Ejector vacuum pumps are divided into: ejector vapor vacuum pumps (vapor – evaporate and gas); ejector hydro vacuum pumps (liquid – evaporate and gas); ejector gas vacuum pumps (compressed air – evaporate and gas). Ejector vacuum pumps are widely applied in many fields where processes take place under pressures lower than the atmospheric pressure. Pump […]
Hydrogenization is one of the most applied procedures in organic synthesis and in industrial applications it is the most used reaction. The hydrogen molecule can enter the reaction faster with more functional groups from any other molecule. Hydrogenization compared to alternative methods for reduction is the most economic. When viewing general trends in hydrogenization technology […]
Ejectors are widely applied in processes of gas and liquid mixing, in the field of chemical technology and many other technical branches. All ejector mixing of gas and liquid can be divided into two groups. The first group: includes ejectors that require pumping in as large amounts of gas per unit liquid flow as possible, […]
From underground water in ejector installations. Distilled water is obtained by destillation (heating by boiling, evaporation and condensation) from surface, water main or well water. There are no dissolved minerals or other admixtures in distilled water so as the chemically and mechanically purest water it is used in the food, pharmaceutical and many other chemical […]
Depending on the type of driving fluid aerators are divided into: ejector hydro aerators ejector gas aerators In many technical fields (chemical, processing and food industry, mining and waterpower engineering) dirty and polluted water, containing undiluted solids of different origin and size, is removed from the production process. Waste water is most often a solution […]
