Analysis of the causes of instrument damage

Good quality products aren’t cheap, and it’s hard to find affordable ones of good quality. The best products require a higher price; it’s up to the suppliers to determine their own quality standards. Conducting user analysis and manufacturer analysis is difficult due to the high requirements involved. The most important thing for instruments is selection.

The original poster probably doesn’t have much experience in this area. First of all, you need to specify which instruments you intend to purchase Only after that can suggestions be given based on each individual instrument. There are specialized areas of expertise, and it’s impossible for any company to produce top-quality instruments in all categories; even if such a company existed, the price would surely be unacceptably high ； Also, the low price is relative – are you purchasing domestically produced products or imported ones? If it’s imported products, do you want to get those from top-quality brands? Second line? Still third-tier? I personally do not recommend purchasing instruments based solely on price. Research and development, production, and after-sales service all require costs; most small manufacturers may lack the capability for research and development, and their after-sales service is also of lower quality. It’s fine as long as there are no problems with these instruments, but once issues arise, those who win bids based on lower prices have no profit left to address such problems, and it is ultimately the client who ends up suffering ； To determine what specific information is needed, we first need to know which instruments you intend to purchase in order to provide targeted advice ； On-site commissioning service can be added at the time of purchase; the manufacturer should be asked to include this service in its quote, but such services are generally charged separately ； Regarding post-sale quality issues, doesn’t the factory where the poster works have any instrumentation staff? Diagnosing and fixing faults are also basic skills for instrument technicians. The last point is the same as what was said on the second floor: you get what you pay for, and it’s necessary to handle each situation accordingly

There are various reasons for the damage. . The process uses incorrect materials; the selection is wrong and the quality of the materials is substandard. . . . Human error. . . Wait

Is the poster a system integration and manufacturing contractor? Provide integrated complete sets of equipment for users? In a situation like that at Even Factory, it’s called skid-mounted equipment; the factory has used some of it, but from the perspective of instrument maintenance by those who use it, well… hehe. . . As long as the project is completed and there are no problems at the beginning of driving, we won’t contact you again. Just take the old man’s head and disappear. Don’t worry about issues such as the remaining lifespan of the equipment’s instruments, malfunctions, repairs, or quality problems. Of course, if the users come to you, your strategy is to take matters into your own hands by using beer bottles and cigarettes to knock out their leaders. If you naively go to the site to replace the instruments on the equipment, you’ll end up in trouble and will never be able to get out of it clean. Hehe. . . . 6 years ago, a set of atmospheric and vacuum distillation columns in the plant used 16 float transmitters manufactured by a company in Dandong. Within less than half a year, various problems arose: zero drift, trembling pointers, damaged adjustment knobs, and so on. The instrument maintenance staff were constantly busy climbing up and down at the site; the ordinary pressure reduction ladders were simply vertical ladders, and having to use them several times a day meant that all the food they ate went to waste. Over time, the instrument technicians began to complain, and eventually the workshop supervisors reported the issue to the procurement department. The procurement team told them to have after-sales service replace the ladders. One day, the manufacturer’s after-sales team arrived, bringing more than a dozen transmitters, and said they would replace them at the site. But the shift supervisor there simply told them to carry out the replacement right at the site. Hehe. . . Although the after-sales technician was a young man from the Northeast who was very energetic, he got extremely tired after climbing the tower and replacing three float transmitters throughout the morning. At noon, he invited my shift leader, and we went to a small restaurant near the factory to eat; I had several times as much alcohol as him. In the afternoon, the after-sales technician just slept in the hotel, while my team was instructed to take the transmitters to the site to replace them. All of the over ten transmitters were located high up on the tower, and we did all the work ourselves. It’s interesting to see how easy it is to work with the clients – a few drinks were enough to get things done.

If the poster is the provider of complete sets of equipment and does not have professional after-sales staff for instruments, I suggest seeking reliable service companies specializing in instrument selection and procurement, so that they can handle the tasks one does not understand.

Party A requested the factory to handle the procurement of the framework without allowing any price increase, and since the factory is not an instrument manufacturing and testing enterprise, there is no need to bear the costs of hiring instrument technicians. It’s just necessary to avoid problems caused by the quality of instrument suppliers, which could lead to troubles for the factory.

Purchasing on behalf of Party A within the established framework means there is no room for adding a price increase; does the project owner have to cover any additional costs incurred by the service provider?

Currently, service-oriented companies don’t have high purchase prices; sometimes, for small-scale purchases, the prices they offer are even lower.

Party A requires the manufacturer to be responsible for purchasing the instruments, but has not provided a specification sheet to the manufacturer? Were no requests made either during the design review process? So the client has to accept whatever is purchased!

The technical specifications are provided by Party A. The factory only handles the procurement on behalf of others, which involves quality risks.
