| 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，必须进一步铜钟 一次性止血带 标志桩模具 钢丝轮 流水槽模具 防撞墙模具 检查井钢模具 不锈钢铸件 模锻件降低泵的振动噪声，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. |
