德国HAMMELMANN高压泵 哈莫尔曼高压柱塞泵清洗设备水泵增压泵喷射泵 pumps 配件 零部件

Founded in 1949 by Paul Hammelmann in Oelde, Westphalia, the company decided to start manufacturing high-pressure pumps and cleaning systems in 1955, thus laying the foundations of the current business. Hammelmann became a pioneer in the field of hydrodynamics and was responsible for many trailblazing innovations. 该公司由Paul Hammelmann于1949年在威斯特伐利亚州厄尔德创立，决定于1955年开始生产高压泵和清洁系统，从而为当前的业务奠定了基础。哈莫尔曼成为流体动力学领域的早行者，并负责了许多开创性的创新。 In endeavoring to solve individual problems and improve existing solutions, the company has grown from modest beginnings into an internationally recognized manufacturer of high-pressure technology products. The plant in Oelde boasts state-of-the-art machinery and covers an area of 30,000 square meters. The DP 60 was the first pump produced in Oelde. It had an operating pressure of 60 bar and a flow rate of 60 l/min and was used for cleaning applications in the paper industry. Today, we can achieve operating pressures of over 4000 bar and flow rates up to 3000 l/min with Hammelmann high-pressure pumps. Decades ago, the point of fitting a cover over a high-pressure unit was just that. Today, the covers have more to do in controlling sound and exhaust emissions. Hammelmann also supplies individual elements such as dust particle filters and electronic microprocessors and controllers. During the mid-1960s, operating pressures only reached 500 bar. In 1974, Hammelmann revolutionized high-pressure technology with the introduction of the friction-free plunger seal assembly. This metal-to-metal sealing system enabled operating pressures of up to 2000 bar to be reached for the first time together with a high service life. In 1969, Hammelmann launched the Dockmaster as the first semi-automatic ship cleaning machine. Today’s version of the unit is environmentally friendly and features direct suction, and is not only used in shipyards but also for the selective removal of concrete in road construction. Nowadays, water tools are used more and more in automatic cleaning processes. Cleaning cast parts is just one of many examples. Whereas these previously could only be cleaned by hand (if at all), robots now carry out the work with the help of high-pressure technology made by Hammelmann. 喷砂,商业清洁,容器清洗,排水清洗,外墙清洗,地板清洗,高压清洗,工业清洗  abrasive blasting,commercial,container cleaning,drain cleaning,facade cleaning,floor cleaning,high pressure cleaning,industrial cleaning 哈莫尔曼高压泵HAMMELMANN柱塞泵清洗水泵选型原则有关知识
以下是相关信息有关HAMMELMANN高压柱塞泵选型原则的相关介绍的详情。
(1)使所选HAMMELMANN柱塞泵的型式和性能符合装置流量、扬程、压力、温度、汽蚀流量、吸程等工艺参数的要求。
(2)必需满足介质特性的要求。
要求轴封可靠或采用无泄漏泵，对输送易燃、易爆有毒或贵重介质的哈莫尔曼高压泵。如磁力驱动泵、隔膜泵、屏蔽泵。
要求对流部件采用耐腐蚀性资料，对输送腐蚀性介质的泵。如AFB不锈钢耐腐蚀泵，CQF工程塑料磁力驱动泵。
要求对流部件采用耐磨资料，对输送含固体颗粒介质的泵。必要时轴封用采用清洁液体冲洗。 (3)机械方面可靠性高、噪声低、振动小。
(4)经济上要综合考虑到设备费、运转费，HAMMELMANN高压泵，维修费和管理费的总成本*低。
(5)离心泵具有转速高、体积小、重量轻、效率高、流量大、结构简单、输液无脉动、性能平稳、容易操作和维修方便等特点。
应尽可能选用离心泵：因此除以下情况外。 选用计量泵。
a有计量要求时。
流量很小且无合适小流量高扬程离心泵可选用时，
b扬程要求很高。可选用往复泵，如汽蚀要求不高时也可选用旋涡泵。
流量很大时,
c扬程很低.可选用轴流泵和混流泵。
可考虑选用转子泵或往复泵(齿轮泵、螺杆泵) d介质粘度较大(大于650~1000mm2/时。
可选用旋涡泵。
e介质含气量75%流量较小且粘度小于37.4mm2/时。
应选用具有自吸性能的哈莫尔曼高压柱塞泵，
f对启动频繁或灌泵不便的场所。如自吸式离心泵、自吸式旋涡泵、气动(电动)隔膜泵。
