Q&A

工作原理

罗茨螺杆真空机组的工作原理结合了罗茨泵和螺杆泵的特点,如下所示:

罗茨泵由两个相互旋转的叶轮组成,这两个叶轮通过齿轮相互啮合但不接触,这可以减少能量损失和摩擦热,叶轮的旋转使气体被吸入泵中,然后被压缩和排出,这种结构使罗茨泵能够在无污染物的高真空环境中工作,并且可以处理大量气体。

螺杆泵部分。螺杆泵通过两个相互啮合的螺杆工作,这些螺杆逐渐挤压气体并将其排出,在螺杆旋转的过程中,气体从入口进入,沿螺旋槽压缩,最后从排气口排出。

结合操作原理。罗茨真空机组运行时,罗茨泵的高效抽吸过程与螺杆泵的压缩和排气过程相结合,实现了真空的快速建立和高效的气体输送。这种类型的装置适用于广泛的应用,特别是在处理含有少量可冷凝气体或少量灰尘的气体时具有明显的优势。



产品特点:

高海拔:极限真空 0.1PA-0.01PA

抽气速率:泵送能力 70L/S-20000L/S

功率: 5.5KW-180KW

因为主泵和前级泵都是无油干式真空泵,所以没有废水和油排放,对环境没有污染。

罗茨泵室和螺杆泵室都可以镀镍和涂PTFE,可以抽出大量的水蒸气和多种腐蚀性介质。

泵腔内没有油,对泵送系统没有污染,可以获得清洁的真空。

无油泵室使溶剂回收非常容易。


What is the warranty policy?
Warranty certificate by beneficiary for a period of 12 months from the date of commissioning or 18 months from the date of shipment whichever is earlier.Any faulty part/components found due to manufacturing dafects during warranty period will be replaced at free of costs. Warranty policies for different models of machines may vary depending on the configuration. You can ask DREAM sales engineers for specific details.
What are some of the lubrication methods for pumps?
Oil-Injected or oil-free are available.
How do you choose the right pump?
It is necessary to inform the sales engineer about the working pressure, exhaust flow and power, as well as other necessary parameter information.
How can I choose the bump? Oil-injected or oil free?
Depending on your industry and production industry requirements, whether there are oil content requirements.
How about the performance of the vacuum pump of DREAM brand?
DREAM brand vacuum pump has high temperature resistance, strong stability, low noise and long-term stable operation.
What are the main features of the DM-系列 罗茨真空泵?
The DM-系列 罗茨真空泵 features an oil-free design, high efficiency, low noise levels, and the ability to handle a wide range of vacuum applications. It is also known for its reliability and durability.
In which industries can the DM-系列 be applied?
The DM-系列 罗茨真空泵 is suitable for use in semiconductor manufacturing, vacuum coating, vacuum drying, scientific research, and aerospace industries, where a high-purity vacuum environment is required.
How does the oil-injected 旋片式真空泵 differ from the DM-系列?
The oil-injected 旋片式真空泵 uses oil for lubrication and sealing, which can provide higher vacuum levels and better performance in certain applications. It is ideal for industrial processes that require continuous operation and higher vacuum pressures.
What maintenance is required for the DM-系列 罗茨真空泵?
Regular maintenance includes checking the seals, cleaning or replacing filters, and inspecting the internal components for any signs of wear or damage. It is recommended to follow the manufacturer's maintenance schedule and guidelines.
How often should the oil be changed in the oil-injected 旋片式真空泵?
The oil should be changed at regular intervals, typically every 3000 hours of operation or as recommended by the manufacturer. Regular oil changes ensure optimal performance and prevent contamination of the vacuum system.
Can the DM-系列 罗茨真空泵 handle corrosive gases?
While the DM-系列 is designed for a wide range of applications, it is not specifically designed to handle highly corrosive gases. For corrosive gas applications, special materials or coatings may be required.
What is the expected lifespan of the DM-系列 罗茨真空泵?
With proper maintenance and care, the DM-系列 罗茨真空泵 can have a long lifespan, typically ranging from several years to over a decade, depending on the usage and operating conditions.
Is the oil-injected 旋片式真空泵 suitable for food processing applications?
Yes, the oil-injected 旋片式真空泵 can be used in food processing applications where vacuum packaging or vacuum drying is required. However, it is important to ensure that the oil used is food-grade and complies with industry standards.
Can the DM-系列 罗茨真空泵 be used in a high-temperature environment?
The DM-系列 罗茨真空泵 is designed to operate within a certain temperature range. While it can handle moderate temperatures, it may not be suitable for extremely high-temperature environments. It is important to check the specifications and consult with the manufacturer for specific temperature limits.
What kind of support and warranty does Dream Compressor provide for their vacuum pumps?
Dream Compressor typically offers comprehensive support, including technical assistance, spare parts, and a warranty on their products. The specific terms and conditions of the warranty may vary, so it is recommended to check the manufacturer's website or consult with a sales representative for detailed information.
