Description
技术领域 technical field
本实用新型涉及一种真空泵，尤其涉及一种直驱高速透平真空泵。 The utility model relates to a vacuum pump, in particular to a direct-drive high-speed turbine vacuum pump.
背景技术 Background technique
随着真空应用技术在生产和科学研究领域中对其抽气量与真空度范围的要求越来越宽，大多需要由真空泵和其它设备组成真空抽气系统共同抽气后才能满足生产和科学研究过程的要求，因此，选用由不同类型真空泵组成的真空抽气系统进行抽气的情况较多，目前使用的有旋片式真空泵、罗茨真空泵和水环真空泵等容积式真空泵，主要应用于电力、化工、轻工、矿山、医药、电子、航天、科研等部门。 As the vacuum application technology has more and more requirements for its pumping capacity and vacuum range in the field of production and scientific research, most of them need to be composed of vacuum pumps and other equipment to form a vacuum pumping system to meet the production and scientific research process. Therefore, there are many situations where a vacuum pumping system composed of different types of vacuum pumps is used for pumping air. Currently, positive displacement vacuum pumps such as rotary vane vacuum pumps, Roots vacuum pumps and water ring vacuum pumps are used, which are mainly used in electric power, Chemical industry, light industry, mining, medicine, electronics, aerospace, scientific research and other departments.
水环真空泵是一种较常见的变容式低压真空泵，带有多叶片叶轮的转子偏心安装在泵体内，旋转时，以水作为工作液体，靠泵腔容积的变化实现吸气、压缩和排气的，所以，需要消耗水与作用于水的能耗，其效率目前为50%左右，转速一般低于3000r/min，控制范围非常有限，一定点后水环会奔溃。 Water ring vacuum pump is a relatively common variable capacity low-pressure vacuum pump. The rotor with multi-blade impeller is eccentrically installed in the pump body. When rotating, water is used as the working fluid, and suction, compression and exhaust are realized by the change of the volume of the pump chamber. Gas, so it needs to consume water and the energy that acts on water, its efficiency is currently about 50%, the speed is generally lower than 3000r/min, the control range is very limited, and the water ring will collapse after a certain point.
另外，ZL200710071245.3“悬臂式高速透平真空泵及其抽真空方法”，ZL200810219408.2“一种多级透平真空机及应用其抽取多级真空的方法”和申请号201010167688.4“高速多级透平真空泵及其抽真空方法”，上述透平真空泵都是通过电机及联轴器带动增速箱增速实现高速，属于定速高速传动，因此存在制造复杂，增加了齿轮传动、联轴器传动、轴承的机械传动效率损耗10%左右以及冷却风扇处能耗，维修复杂、占地面积大，增加了增速箱与联轴器处机械故障点，定速传动不易实现可变的抽吸工艺需要等缺点；对于多级透平真空泵而言，一旦出现故障，会停及整条生产线，严重影响正常生产与造成很大的经济损失，且检修周期较长。 In addition, ZL200710071245.3 "cantilever high-speed turbo vacuum pump and its vacuum pumping method", ZL200810219408.2 "a multi-stage turbo vacuum machine and its application Flat vacuum pump and its vacuum pumping method”, the above-mentioned turbo vacuum pumps all drive the speed increase box to achieve high speed through the motor and coupling. , The mechanical transmission efficiency loss of the bearing is about 10% and the energy consumption at the cooling fan, the maintenance is complicated, the floor area is large, and the mechanical failure points at the gearbox and the coupling are increased, and it is difficult to achieve a variable suction process with a fixed speed transmission Necessary and other disadvantages; for multi-stage turbo vacuum pumps, once a failure occurs, the entire production line will be stopped, seriously affecting normal production and causing great economic losses, and the maintenance period is long.
根据容积式真空泵电耗或水耗高的不足，同时针对普通定速高速透平真空泵增速传动损耗较大、存在故障点隐患多等缺点，结合透平真空泵的高效、高速紧凑、大抽气量等优点，在满足不同的抽气量、真空度工艺要求的同时，最大程度地提高生产效率，并使故障引起的生产损失降到最低，进一步考虑一种全新的直驱单级或双级高速透平真空泵是非常具有应用价值与现实意义的，以适应现代工业对真空抽取与压缩设备高效环保的最大化等方面的发展需要；这是本实用新型的出发点。 According to the lack of high power consumption or water consumption of positive displacement vacuum pumps, and at the same time aiming at the shortcomings of ordinary fixed-speed high-speed turbo vacuum pumps, such as large speed-up transmission loss and many hidden dangers of failure points, combined with high-efficiency, high-speed, compact, and large pumping capacity of turbo vacuum pumps and other advantages, while meeting the requirements of different pumping volumes and vacuum degrees, it can maximize production efficiency and minimize production losses caused by failures. Further consider a new direct-drive single-stage or double-stage high-speed The flat vacuum pump is very valuable in application and practical significance, so as to adapt to the development needs of modern industry in terms of maximizing the efficiency and environmental protection of vacuum extraction and compression equipment; this is the starting point of the utility model.
