One of the most common types of fluid transfer pump is the water pump. The term “metering pump” is based on the application or use rather than the exact kind of pump used, although a couple types of pumps are far more suitable than most other types of pumps. Attached to the intake check valves are tubes or hoses, which connect it to a fluid reservoir. That’s when they came up with the piston pump, also known as the suction pump, which works using atmospheric pressure. They also love them because they send out a liquid cyclically on a consistent basis.Metering pumps are used for applications related to commercial vending, food and beverage processing, healthcare, irrigation, laboratory research, chemical engineering and processing, metalworking, milling, pharmaceuticals, plastic fabrication, petroleum and gas, water treatment, and more.Metering Pumps – Primary Fluid Systems Inc. Mainly during this time, manufacturers used pumps to control canal locks and various forms of water flow, though they did not control water flow directly. With early piston pumps, miners were able to force water from inaccessible areas into pump cylinders, then release it elsewhere out of outlet valves, so that they could mine those areas. It wasn’t until the Middle Ages that people began to take a renewed interest in pumps and what they could do. During this time, they developed a number of other pumps. History Humans have been using pumps since at least the dominant years of Rome. The pump itself is a pressurizing device often capable of exceeding its pressure rating, although not guaranteed to. A single-piston pump delivers liquid to the outlet only during the discharge stroke. Liquid Type It is important to understand the type of liquid that will flow through a pump for a few different reasons. One of the best sources on pumps from the 1500s comes from De Re Metallica, a 1556 work by Georgius Agricola. The outlet valve allows flow from the chamber to the outlet line, but not in reverse. شیرهای Back Pressure :از آنجا که پمپ های مترینگ بایستی دوز صحیحی از سیال را پمپاژ نمایند، در حالاتی که اختلاف فشار خط رانش و مکش کمتر از5/1 توشه باشد، استفاده از همین شیر سفارش می شود. به طور معمول دوز همین دوزینگ پمپ ها دربین 1 لیتر بردقیقه تا 1000 لیتر بر دقیقه و فشار کاری دوزینگ پمپ ها 1 تا 2000 bar متغیر میباشد. اگر شما این مقاله را تحسین می کنید، مایلید داده ها بیشتری در آیتم موتور دوزینگ بدست آورید به وب سایت ما مراجعه کنید.
