| 真空泵分类 Classification of vacuum pumps 液环泵 Liquid ring pump 虽然液环泵属于粗真空泵，但在中国的石油、化工、电力、轻纺、造纸、医药等领域仍然有着很大的市场。液环泵工作原理在国外，液环泵的销售额占全部真空泵市场的14%，仅次于干泵，由于液环泵大部分是铸件，加工要求也不高，属劳动密集型产品，所以国产液环泵在价格上有竞争优势，关键是要改进设计，缩小体积，减轻重量，提高效率，降低能耗。 Although the liquid ring pump belongs to the crude vacuum pump, it still has a large market in China's petroleum, chemical industry, electric power, light textile, paper making, medicine and other fields. The working principle of liquid-ring pump abroad, the sales of liquid-ring pump accounts for 14% of the total vacuum pump market, second only to dry pump. Because most of the liquid-ring pump is castings, the processing requirements are not high, and it belongs to labor-intensive products, so domestic liquid-ring pump has competitive advantages in price. The key is to improve the design, reduce volume, reduce weight, improve efficiency and reduce energy consumption. 滑阀泵 Slide valve pump 由于滑阀泵比较耐用、可靠，国内外各种真空炉、镀膜机以及干燥、浸渍等设备都是用滑阀泵作为前级泵，滑阀泵工作原理但是滑阀泵铸件重，加工工作量较大，所以国外各真空厂都在中国寻找合作伙伴。为了使国产滑阀泵能够进入国际市场，必须进一步降低泵的振动噪声，杜绝喷油和漏油，提高滑阀泵长期运行的可靠性。 Because the sliding valve pump is durable and reliable, all kinds of vacuum furnaces, coating machines, drying and impregnation equipments at home and abroad use the sliding valve pump as the front pump. The working principle of the sliding valve pump is heavy, but the casting of the sliding valve pump is heavy and the processing workload is large, so the foreign vacuum factories are looking for partners in China. In order to make domestic spool pump enter the international market, it is necessary to further reduce the vibration and noise of the pump, eliminate oil injection and leakage, and improve the reliability of long-term operation of spool pump. 直联旋片泵 Straight-coupled rotary vane pump 随着真空技术在各个应用领域的不断扩大，直联旋片泵的需求量越来越大。由于这种泵数量很多，加工装配工作量很大，价格又很低，所以有的国外真空厂商在中国建立专业厂。国产中小型直联旋片泵在技术上已经过关，价格又远比国外的泵便宜，所以国产泵仍然有竞争优势，关键是要解决轴封漏油以及旋片材料和真空泵油的性能质量问题，确保直联泵在高速、高温下性能稳定和运行可靠，同时还要进一步提高国产直联旋片泵抽除水蒸气的能力。 With the continuous expansion of vacuum technology in various application fields, the demand of direct-coupled rotary vane pump is increasing. Because of the large number of such pumps, the heavy workload of processing and assembling, and the low price, some foreign vacuum manufacturers have established specialized factories in China. Domestic small and medium-sized direct-coupled rotary vane pumps have passed the technical barrier and their prices are much cheaper than those of foreign pumps. Therefore, domestic pumps still have competitive advantages. The key is to solve the problems of oil leakage from shaft seals, the performance and quality of rotary vane materials and vacuum pumps, to ensure the stable performance and reliable operation of direct-coupled rotary vane pumps at high speed and high temperature, and to further improve the steam extraction of domestic direct-coupled rotary vane pumps. Ability. 罗茨泵 Roots pump 从国外罗茨泵生产情况来看，国外几家大公司，如Leybold、Balzers、Alcatell、Edwards和ULVAC，他们各家罗茨泵的销售额占全球罗茨泵销售额的比例都没超过5%，这5家总计才20%，罗茨泵产量不大，但国外罗茨泵罗茨泵工作原理的价格远比国产泵要高得多。国内外几乎所有大型或小型的高真空和中真空系统，为了缩短抽气时间、提高生产效率都配有罗茨泵，所以国产罗茨泵一定要在占领国内市场基础上设法进入国际市场，这样就必须进一步降低国产罗茨泵的振动噪声，彻底解决轴封漏油问题，改进泵的外观质量，提高泵内的光洁度和清洁度。另外，还要考虑到有些国家和地区的电源频率为60Hz，更要确保罗茨泵在提高转速的情况下长期运行的可靠性。 Judging from the production situation of Roots pumps abroad, several large foreign companies, such as Leybold, Balzers, Alcatell, Edwards and ULVAC, account for less than 5% of the global sales of Roots pumps. The total output of these five pumps is only 20%. Roots pump output is not large, but the working principle price of Roots pump abroad is much higher than that of domestic pumps. Almost all large or small high vacuum and medium vacuum systems at home and abroad are equipped with Roots pumps in order to shorten the pumping time and improve production efficiency. Therefore, domestic Roots pumps must try to enter the international market on the basis of occupying the domestic market. In this way, we must further reduce the vibration and noise of domestic Roots pumps, thoroughly solve the problem of oil leakage from shaft seals, and improve the appearance quality of pumps. High cleanliness and cleanliness in the pump. In addition, the power supply frequency of some countries and regions is 60 Hz, and the reliability of long-term operation of Roots pump under the condition of increasing speed should be ensured. |
