W Series Hydraulic Jet Pumps - Working Principle and Applications

Overview: The W Series hydraulic jet ejector is a mechanical device with three effective functions: vacuum extraction, condensation, and drainage. It operates by utilizing a stream of water under pressure, which is ejected through symmetrical, evenly distributed nozzles at a certain angle, converging at a focal point. Due to the high velocity of the jet stream, a negative pressure is formed around it, creating a vacuum inside the chamber. Additionally, due to direct contact between the secondary steam and the jet stream, heat exchange occurs, with most of the steam condensing into water. A small amount of uncondensed steam and non-adhering gases are also mixed and compressed by friction with the high-speed jet stream, and are then expelled through an expansion pipe, further enhancing the vacuum inside the chamber. The hydraulic jet ejector is widely used in vacuum and evaporation systems for processes such as vacuum pumping, vacuum evaporation, vacuum filtration, vacuum crystallization, drying, and deodorization, and is a widely demanded equipment in sugar, chemical, food, salt, flavoring, milk, fermentation, and some light industry and defense sectors. (Materials: Stainless Steel, Cast Iron) The steam jet ejector is a hydraulically connected steam pump, a novel device that uses water and steam jet suction to obtain vacuum. A centrifugal pump increases the pressure of static water, and the pressure water is jetted out of the steam nozzle at high speed, lowering the pressure at the nozzle exit to form a vacuum, drawing in external gases (liquids), and then they enter the mixing pipe together. The SPB type glass fiber reinforced plastic hydraulic jet vacuum pump is used in conjunction with the glass fiber jet ejector, which, when equipped with a corresponding centrifugal pump, can be used for vacuum extraction. The ejector does not require elevated installation and can be installed on flat ground. The ejector offers the advantages of easy installation, no maintenance required, and affordability. The glass fiber reinforced plastic molded jet ejector, in addition to the anti-corrosion characteristics of the jet ejector, also has the advantages of high molding density, smooth and solid inner and outer surfaces, high durability, and excellent corrosion resistance, making it comparable to stainless steel components.

W-Type Hydraulic Jet Ejector Features:

The hydraulic jet unit is compact in structure and boasts high strength, suitable for use in vacuum evaporation systems. By integrating the condensation function of the condenser with the suction function of the vacuum pump into a single unit, it significantly simplifies the process flow. Compared to the previous setup using a vacuum pump and an outdated condenser, it eliminates the need for the vacuum pump, condenser, separator, and other equipment, and also offers the following advantages:

1. The hydraulic jet pump is compact, lightweight, and energy-efficient, offering double the performance at a lower power consumption than a vacuum pump system, making it an attractive investment.

2. Easy to operate and convenient for maintenance; no need for dedicated personnel management. Due to the absence of mechanical transmission parts, it operates with low noise and does not require lubricating oil.

3. Suitable for outdoor ground-level installation, requiring minimal land area, thus saving on factory building space and installation costs.

W-Type Hydro-Jet's Application:

Hydro-jet nozzles are widely used, primarily in vacuum and evaporation systems for processes such as vacuum pumping, vacuum evaporation, vacuum filtration, vacuum crystallization, drying, and deodorization. They are essential equipment highly demanded in industries like grain processing, chemicals, food, salt production, monosodium glutamate, milk, fermentation, and certain light industry and defense sectors.

W-Type Hydraulic Jet Ejector Structural Description:

The hydraulic jet nozzle is composed of components such as the body, cover, nozzle, nozzle seat plate, guide disk, diffuser tube, and check valve. The nozzle is made of stainless steel, the nozzle seat plate is machined from steel, and the remaining parts are cast iron. The nozzle features a multi-nozzle structure to achieve a larger water-vapor contact area, facilitating heat exchange and achieving better vacuum effects. The nozzle seat plate is precision-machined to ensure the jet water converges accurately at a single focal point. The guide disk is used to slow down the steam (or air) flow rate, evenly introducing the steam into the chamber to prevent the jet water from being deflected and reducing the suction efficiency.
