A rotary vane vacuum pump is one of the four main types of rotary pumps, in current society a vane pump has many usages, such as agricultural production, industrialization or transportation industry, etc. Next we will learn the definition of rotary vane pump and what it can be used for.

A vacuum pump is a device or equipment that uses mechanical, physical, chemical or physical chemical methods to pump the pumped container to obtain a vacuum. In layman's terms, a vacuum pump is a device that improves, generates and maintains vacuum in an enclosed space by various methods. How to choose the right vacuum pump? This article will list nine aspects for your reference.

In recent years, a new type of vacuum pump that can be achieved from atmospheric pressure to high vacuum with only one pump has been developed, but generally speaking, for obtaining high vacuum, ultra-high vacuum and extremely high vacuum, multiple vacuum pumps are connected in series to complete the pumping task. Thus, knowing the type of pumps properly is important for user to choose affordable and suitable vacuum pump.

With the construction and development of industry, many industries such as metallurgy, electronics, and coating have put forward higher requirements for the extraction of gas or particles from equipment. The large demand for industrial production and the rapid development of technology have made the production process of vacuum pumps continue to improve. Gradually occupy a larger market share in industrial production. With the continuous improvement of the level of vacuum pump manufacturing technology, the structural design of vacuum pumps is more refined, and different equipment structures also enable vacuum pumps to work in different industrial environments. Different types of vacuum pumps are driving the industry with a rapid growth momentum. Rapid development. The following form is a brief list of common problems and maintenance methods.

The quality of the vacuum pump is decided by its mechanical structure and the quality of the oil, it must be well protected when using the vacuum pump. When using distilling volatile organic solutions, it will be absorbed oil that will lead to the increase of vapor pressure and the decrease of vacuuming efficacy. If it is acid gas, it will corrode the oil pump, and if it is steam, it will destroy the vacuum pump from turning oil into emulsion.

Vacuum pump is a kind of equipment that evacuates the pumped container to obtain a vacuum by means of mechanical, physics, chemistry or physical Chemistry methods. The gas is absorbed in from the air inlet and enters the cavity of the frontline pump through the ventilation/isolation valve. In the pump, the gas is conveyed. When the inlet is closed by the blade, the gas is conveyed and compressed. During the transferring process, the oil is transferred from the oil injection port and inhaled into the cylinder.

The installed rotor of a rotary vane vacuum pump is tangent to the stator fixed surface inside the pump eccentric, two or more rotary vanes slide in the rotor slot and contact with the inner wall of the stator, which makes the pump chamber divided into several variable volumes.

Generally, the clearance between the rotary vane and pump chamber is sealed by oil, so the rotary vane vacuum pump is usually an oil seal mechanical vacuum pump.

The rotary vane vacuum pump can remove the dry gas from the sealed container. It can remove a certain amount of condensable gas if it has gas ballast device. However, it is not appropriate to remove some gases that are highly oxygenated, corrosive to metals, react chemically to pump oil, and contain particulate dust.

The rotary vane vacuum pump failure is divided into operation failure and performance failure.
