Vibration is the important role of analysis in the equipment testing

Abstract: vibration is the important role of analysis in the equipment testing information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Enterprises to implement equipment management modernization, should actively introduce advanced equipment management methods and on the basis of the equipment condition monitoring of equipment maintenance technology. Equipment state monitoring and fault diagnosis technology is the precondition of equipment preventive maintenance. Especially in the heavy industrial. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the important function of the vibration in equipment testing analysis article details. Enterprises to implement equipment management modernization, should actively introduce advanced equipment management methods and on the basis of the equipment condition monitoring of equipment maintenance technology. Equipment state monitoring and fault diagnosis technology is the precondition of equipment preventive maintenance. Especially heavy industry enterprises, the strong continuity and high safety and reliability requirements, through the condition monitoring of promotion, can gradually master the water pump, fan and other large and medium-sized equipment working condition, to put an end to forced outage loss. A, equipment management status before large water pump, fan and other large and medium-sized equipment, the determination of minor repair cycle generally has two kinds: run units or regular maintenance. Hours according to the actual operation and equipment operation condition, to determine the equipment repair cycle, cycle, or equipment running status is poorer, notify the maintenance personnel of equipment overhaul, based on years of experience, some equipment also determine the minor repair cycle, water pump a year for an overhaul cycle, each year production peak, need more water, for all the pumps for maintenance. And fan run more frequently, in order to improve the efficiency of purification or normal feeding of the electrolytic cell, repair cycle may be classified as six months, whether in Taiwan or in the year to determine the overhaul period method, are too old. If you want to come out from the traditional maintenance mode, must rely on advanced scientific instruments as a means of detection. 2, vibration is equipped with qinghai aluminum companies in the equipment management institution, depending on the division of work, equipped with different detecting instrument, the equipment department specially equipped with Beijing Beijing navigation company production of HG 3518 type instrument, a data acquisition system of fault diagnosis, measurement parameters for acceleration, velocity, displacement, temperature and speed. For factory check, equipped with the French production 4576 da multi-functional portable vibration meter, measuring parameters such as acceleration, velocity, displacement, is mainly used for random testing equipment running status. Master the basic parameters of test maintenance personnel, equipped with Beijing Beijing navigation company production of HG a type 2506 pocket-sized vibration, is suitable for low frequency ( 5Hz） The measured acceleration, velocity, displacement, etc. Three, the usage of vibration in recent years, many enterprises in the aspect of equipment condition monitoring using pulse vibration, oil analyzer, multi-channel chronograph instrument, etc. Due to the lack of regulations and technical guidance, equipment issued to the workshop, because the technical level is differ, the instrument performance is not stable, the operation is not convenient and so on various reasons, it is difficult to carry out the work. But after a period of groping, the branch of China aluminium company each equipment have been introduced in the tally, the introduction of many advanced equipment, the vibration detector is applied to equipment state inspection, plays an important role in equipment preventive maintenance, the work of equipment management to a new level. Four, measuring method and judging on the basis of 1, selecting is: use of vibration, bearing and axial endpoint of main equipment testing, and is equipped with site inspection record, each measuring point must be corresponding to each other. 2, measuring cycle: just after overhaul or close to the device overhaul, need to two weeks a measurement; When the normal operation of the test once a month; In case of the measured value and the last measured value have obvious changes, should strengthen the density of the test, in case of accident caused by the downtime. 3, measured value judgement basis: ISO2372 with reference to international standards. Speed: 600 ~ 1200 r/min, vibration measuring range: 10 ~ 1000 hz. Usually in the normal operation of equipment, its detection speed value in 4. 5 ~ 11. 2mm／s（ More than 75 kw unit) Used for monitoring scope, more than 7. More than 1 mm/s consider arrange repair. The determination of this number, besides considering equipment motor capacity to consider working continuity is strong, high safety and reliability. The company through the application of vibration on the management, get the enlightenment to the following several aspects: 1, the application of vibration to detecting state of device, although not as the only basis determine equipment overhaul period, but as a condition of reference is very necessary.

At the same time, as the recent research of Sincerity shows, the benefits of improved productivity and firm performance can make implementing basic management practices worth it.

Being a performance leader means Beijing Sincerity Automatic Equipment Co., Ltd will achieve operational excellence, industry-leading customer satisfaction and superior financial performance.

The development of coriolis density meter mass flow meter products has massive potential for expansion.
