Roots flowmeter scale maintenance tips

Abstract: the roots meter scale maintenance of secret information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Maintenance of flowmeter which is our indispensable in the process of use, and is particularly important, today Jiang Sujin source instrument is for everyone to introduce roots flowmeter maintenance tips. Main method basically has the following several ways: 1, the header. More flow meter manufacturers choose model price quote you are welcome to inquire, here is roots meter scale maintenance tips article details. Maintenance of flowmeter which is our indispensable in the process of use, and is particularly important, today into the source of instrument was introduce roots flowmeter maintenance tips for you. Main method basically has the following several ways: 1, the header should have a certain number of lubricating oil, lubricating oil is commonly silicone oil or arsenic. 2, should be regular inspection on time, listen to: whether there is a noise; See: header mechanical counter any jam, records are continuous. 3, should be cleaned once every six months the filter, filter blockage judging from import and export pressure difference. General differential pressure more than 0. 07 mpa should clean processing. 4, the header gear transmission parts should be cleaned every year, inspection, lubrication, and the meter calibration. 5, the accuracy of temperature compensator corrector should check once a year, and the gear transmission parts cleaning lubrication. 6, within the scope of use prescribed by the flow meter, not overrun; Overload 20% May not be in 30 minutes, otherwise it will reduce the accuracy of measuring. 7, don't make the fluid backflow, on-site display pointer or counter the word wheel turn back, should be inspected in order to avoid the accident. 8, 40 or 60 mesh filter application/inch stainless steel wire mesh. 9, should check the magnetic coupling or mechanical and magnetic coupling transmission, check whether magnetic field strength is enough, enough should update magnetic steel. Before 10, enable shall, first of all, slowly open the bypass valve and then open the inlet valve of the flow meter, and then open the outlet valve, open the outlet valve at the same time, must keep an eye on meter pointer movement speed, normal work, and then close the bypass valve, such as abnormal, should immediately open the bypass valve, close the entrance valve at the same time, check processing. Xinan line or after repair, 11, a day after putting-in-service proactively, must open the filter to remove impurities. Normal use, light oil, heavy oil for 3 months, six months must clean strainer, purge steam flow meter is strictly prohibited. 12, replacement of graphite bearing, we have to (flowmeter, zui big gap less than 0. 1毫米; To 6 meter, zui big gap less than 0. 2毫米; Of upper and lower cover and the clearance between the rotor and rotor with metering box cavity gap zui big value should be not more than 0. 15mm。 13, maintenance is disassembled, the important parts should be ready in order to avoid mistake. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
