Fiery struggle.
Wordless perseverance.
"We've got to gnaw on this hard bone!”
Oops, boy, how many times have I said it, this is a common problem of UPS, no matter what brand has such a small problem......”
Hanging up the manufacturer's **, Xiao Huang, a young technician in the power administrative support department, still frowned, staring at the UPS equipment that failed again in front of him and fell into contemplation.
UPS power supply is the "life-lasting" artifact of model power supply, which can continuously transmit electric energy when the mains power is flashed off and the voltage fluctuation is too large, so as to ensure that the test equipment is not affected. However, when the main machine is turned on and the static switch is converted, the instability of the voltage may bring the risk of module burnout. If an abnormality occurs, the method of updating parts is often used for maintenance, which cannot fundamentally solve the problem, and the fault may still appear again.
To this end, the center has selected a backbone of party members with excellent technology and Xi learning initiative to set up a UPS independent maintenance team. Xiao Huang secretly made up his mind: "UPS equipment gradually transitions from the manufacturer's after-sales service to our independent maintenance, which is a test of our trust and the end of the yearWith a pragmatic and more serious work style, Xiao Huang took the team members to plunge into the study of this "common problem", consulting information, consulting manufacturers, and spare parts operation ......
The board is burned, it may not be the cause of the board itself, can you start with the input voltage and harmonics?”
With such an idea, Xiao Huang led the team members to install a specific isolation transformer at the power input end, and after many tests and pilot installation and operation, the equipment was in good condition, and there was no plate burning. After the problem was solved, the UPS independent maintenance team breathed a sigh of relief from the bottom of my heart. The manufacturer's after-sales maintenance personnel also sincerely sighed: "There is still such an operation." It is through the exploration and efforts in this matter that the team members have a deeper understanding and mastery of the structural characteristics, operating principles and fault maintenance of UPS equipment.
In the subsequent work, this young team made persistent efforts to optimize the design of the power switching circuit, adopt static power switching, install synchronous voltage stabilizing devices, boldly calculate, carefully verify, and once again overcome a number of technical difficulties such as abnormal switching of UPS power supply caused by power harmonic mismatch, and also laid the foundation for comprehensive independent maintenance in the future.
"You can't wait passively, you have to take the initiative!”
Towards the end of the year, the processing tasks of multiple models of mirrors of the 508 Advanced Optical Manufacturing Division entered the stage of high-precision completion, which required precise modification of ion beam polishing to achieve the final convergence of the surface shape. The 2-meter ion beam polishing machine indicates a passive situation of serious congestion in production scheduling.
The division has been equipped with a domestic ion beam polishing machine this year, and since November, the manufacturer has begun to install and debug in full swing. "You can't wait passively, you must take the initiative to get started, and grab both new and old equipment!The team leader Meng made up his mind to convene key members Xiao Li and Xiao Zhang to discuss countermeasures and act quickly.
Xiao Li is the senior helmsman of the 2-meter ion beam polishing machine, based on rich processing experience, he reasonably plans the task sequence, and adopts the mode of "one cabin with multiple mirrors and group processing", which effectively improves the processing efficiency and relieves the pressure on the back-end. At the same time, in the gap between multi-mirror clamping, Xiao Li carefully checked the movement mechanism and ion source characteristics of the machine tool to ensure that the equipment was trouble-free and stable.
The old equipment has been fully utilized, and the new equipment still needs to be put into use as soon as possible. Xiao Zhang, a young employee, took on the role of commissioning supervisor. Under the guidance of the old employees, he quickly grasped the key points of commissioning, combined with the commissioning personnel of the manufacturer, optimized various indicators, and made the equipment enter the trial processing stage in advance. In the trial processing, several backbones comprehensively compared the first and experimental data, and quickly solved the core problems such as low convergence rate by optimizing the removal function and accurately adjusting the half-height and width. The main functions and performance of the new equipment are debugged in place, and the equipment is basically in use, which is nearly one month ahead of the manufacturer's commissioning plan.
Standing in front of the domestic ion beam polishing machine, looking at the detection data of a certain mirror processed out of the cabin, Lao Meng breathed a sigh of relief - the precision polishing of the business department really jumped out of the "cage" of single-point equipment, and made a substantial breakthrough in the bottleneck blocking point that restricts production capacity.
"Star-chasing youth", running hard
In the winter of Xi'an, the wind is changeable. At noon, the wind carries a warm warmth of a small spring, making people feel that autumn is not far away. But in the evening, the temperature plummeted, and the wind at this time took off its warm robe to reveal its cold claws, and it was caught off guard on the roof of the building, which made people shiver.
Received a star, received a star......This sentence was like a thunderclap, and like a warm current, everyone was excited. The people who were modifying **, the people who checked the ephemeris, and the people who checked the antenna link design immediately gathered in front of the monitoring screen, staring at the green lights that represented the lock. Seeing the number of receipts constantly beating, this group of "star-chasing youths" could no longer feel the chill on the roof at the moment, but they could hear each other's excited heartbeats.
Take a quick look at the data you receive is ......”
Don't worry, when this track is finished, it won't be the first product to receive stars, look at what excites you. ”
This is the scene where the team of a room electric scanning product line of the Xi'an branch of Aerospace Stellar is independently developing the first all-digital spherical phased array antenna. Four months ago, starting from scratch;From research, making plans to product assembly and production, debugging and testing, team members run hard day and night chasing the stars. The R&D team has discussed and analyzed the requirements in the project indicators for many times, refined the development plan, and implemented each product indexThe members of the production team work tirelessly to ensure the high-quality production of productsThe test team carefully sorted out the product test methods and test items, and tested and debugged all the components and product functions one by one to ensure that each link was fully tested.
The data is correct. ”
The afterglow of the sunset on the horizon is more like the dawn of dawn. The actual performance of the antenna in receiving low-orbit satellite data is good, which indicates that the laboratory has successfully mastered the core technology of spherical phased array antenna and achieved a new breakthrough in the development of phased array antenna.
In this way, the "star-chasing youth" sounded the horn of victory after countless setbacks and failures, and laid the cornerstone of technological innovation and development with sweat. Every morning and twilight, in the visible and unseen, is an ideal battlefield.
