Wenling Hongbaoshi Vacuum Equipment Factory

Wenling Hongbaoshi Vacuum Equipment Factory is located in the beautiful and convenient city of Taizhou, Zhejiang. We are a modern enterprise engaged in the research, development, manufacture and marketing of pumps. Following the tenet of "Customer-oriented", our company has successfully developed some vacuum products which are welcomed by clients.
A vacuum pump is a device that removes gas molecules from a sealed volume in order to leave behind a partial vacuum.
Uses of vacuum pumps

Vacuum pumps are used in many industrial and scientific processes including:
Composite Plastic moulding processes (VRTM)[1]
Driving some of the flight instruments in most aircraft.
The production of most types of electric lamps, vacuum tubes, and CRTs where the device is either left evacuated or re-filled with a specific gas or gas mixture
Semiconductor processing, notably ion implantation, dry etch and PVD, ALD, PECVD and CVD deposition and soon in photolithography
Electron microscopy
Medical processes that require suction
Uranium enrichment
Medical applications such as such Radiotherapy, Radiosurgery, Radiopharmacy
Analytical instrumentation to analyse gas, liquid, solid, surface and bio materials
Mass spectrometers to create an ultra high vacuum between the ion source and the detector
Vacuum Coating for decoration, for durability, for energy saving
Glass coating for low e glass
Hard coating for engine (as in Formula One)
Ophthalmic coating
Milking Machines
Air conditioning service - removing all contaminants from the system before charging with refrigerant
Trash compactor
Vacuum engineering
Sewage systems (see EN1091:1997 standards)
Freeze Drying
As the main source of vacuum in dairy shed plant
Vacuum may be used to power, or provide assistance to mechanical devices. In diesel engined motor vehicles, a pump fitted on the engine (usually on the camshaft) is used to produce vacuum. In petrol engines, instead, vacuum is obtained as a side-effect of the operation of the engine and the flow restriction created by the throttle plate. This vacuum may then be used to power:

The vacuum servo booster for the hydraulic brakes
Motors that move dampers in the ventilation system
The throttle driver in the cruise control servomechanism
In an aircraft, the vacuum source is often used to power gyroscopes in the various flight instruments. To prevent the complete loss of instrumentation in the event of an electrical failure, the instrument panel is deliberately designed with certain instruments powered by electricity and other instruments powered by the vacuum source.
