W Series hydraulic jet pumps operating 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 nozzles with a certain inclination, 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, the secondary steam comes into direct contact with the jet stream, facilitating heat exchange, with the vast majority of the steam condensing into water. A small amount of uncondensed steam and non-adherent gases, after interacting with the high-speed jet stream through friction, mixing, and compression, are 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. It 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 type of hydraulic jet combined with a steam pump, which is a novel device that uses water and steam jet suction to obtain vacuum. The centrifugal pump increases the pressure of the static water, and the pressurized water is ejected at high speed from the steam nozzle, lowering the pressure at the nozzle exit to create a vacuum, which then draws in external gases (liquids) into the mixing pipe. Together with the SPB type glass fiber reinforced plastic hydraulic jet vacuum pump, it can be used in conjunction with the glass fiber jet ejector. Equipped with a corresponding centrifugal pump, the vacuum jet ejector can be installed without a high position requirement, simply on flat ground. The ejector offers the advantages of easy installation, no maintenance required, and affordable pricing. The glass fiber reinforced plastic molded jet ejector, in addition to the anti-corrosion characteristics of the jet ejector, also boasts high molding density, smooth and solid inner and outer surfaces, enhanced durability, and superior anti-corrosion properties, making it comparable to stainless steel components in beauty.

Features of W-type hydraulic jet ejector:

The hydraulic jet unit is compactly structured with high strength, suitable for use in vacuum evaporation systems. By combining the condensing action of the condenser with the exhaust function of the vacuum pump into a single device, the process flow is significantly simplified. Compared to the original setup using a vacuum pump and an old-style condenser, it eliminates the need for the vacuum pump, condenser, and separator, among other equipment, and offers the following additional advantages:

1. The hydraulic jet pump is compact, lightweight, and structurally dense, boasting high efficiency and lower power consumption compared to vacuum pump systems, making it an attractive investment for investors.

2. Easy operation and convenient maintenance; no need for dedicated personnel management. Due to the absence of mechanical transmission parts, the noise level is low and lubricating oil is not required.

3. Suitable for outdoor ground-level installation, occupying minimal space; this can save on factory building area and installation costs.

W-Type Hydraulic Jet Ejector Application:

Hydraulic jet ejectors 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 the grain, chemical, food, salt, monosodium glutamate, milk, fermentation, and some 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 pipe, and one-way 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-gas contact area, which is beneficial for heat exchange and achieves a better vacuum effect. The nozzle seat plate is precision-machined to ensure that the jet water is accurately focused at a single point. The guide disk is used to slow down the flow of steam (or air), evenly introducing it into the chamber to prevent the jet water from being deflected and reducing the suction efficiency.
