1 hiborg/ht-03a cooler failure maintenance
1. The cause of the failure can be judged on the basis of failure, regardless of the brand。
Two, you can explain the cause of the failure, so we can find a solution for you at the cold water inner plant。
According to your model, you have a cold 3-hp cooler, a high-pressure alert for general failure, a 3-380-v reverse, a missing alarm, etc。
4. High pressure alerts may determine the cause of failure based on high pressure pressure, missing phase, and checking the normality of the three-phase power supply。
2. How to maintain the cooler
It's nice to have you here at the geigers factory
1. Refrigerators operating from the beginning to the beginning: frequent observation of the compressor's oil surface, the return of oil and its cleanness, and timely replacement or addition of oil when it is discovered that the oil is dirty or the oil surface is declining, so as not to cause poor lubrication and affect the operation of the chiller。
2. For wind cold water chillers: frequent cleaning of wind chillers to keep them in a good state of heat exchange, regular checking of condensers for any problems with condensation, and timely cleaning of water。
For water coolers: frequent check of the mixing of cooling water, such as when it is too dirty, and replacement. Check whether the water system has run, run, drop, leak. Whether the pumps are working properly, whether valve switches are effective and cooling water towers and wind machines are normal。
For wind chiller-type evaporaters: frequent screening of frosting, if it is effective in a timely manner, can affect cooling effects and lead to re-liquidation of the refrigeration system。
Regular observation of the operation of compressors and inspection of their exhaust temperature, with special attention to the operation of the system during the change season, and timely adjustment of the system's fluid supply and condensation temperature。
5. Pay careful attention to compressors, cooling towers, pumps or condensers, which operate in an exceptional and timely manner, while checking the vibrations of compressors, vents and pumps。
6. Maintenance of compressors: the initial system was less clean and replaced once after 30 days of operation with refrigerated oil and dry filters and once more after six months of operation (depending on the circumstances). For more cleaner systems, refrigerated oil and dry filters are also replaced after six months of operation, depending on the circumstances。
3 how the cooler works
I'm glad the cedric cooler answered
[summary of maintenance of cold water units] as social science advances, demands on industrial production levels grow, and some enterprises overload various production machines or auxiliary machines in order to satisfy process production, leading to damage to machines. Similarly, in the refrigeration sector, where firms are operating 24 hours a day in order to catch goods, the production machine will cool down, and the yang cold water unit will be overloading, making problems easier, after all, because cold water units are consumables, not durables. The repair and maintenance of the cold water crew is very important。
The parts must be the original parts
When machines operate for long periods of time or overload, the machines generally suffer from reduced efficiency (deficit of refrigerants, condensers, leaks in copper pipes, etc.) and wear and tear of accessories. In the above cases, operators do not repair and purchase accessories on their own (a one-year warranty period for a general cold water machine) and call the plant for free maintenance during the warranty period (additional parts), such as replacement of self-replacement parts without warranty. The spare parts on the market are mixed and the general population does not see the good or the bad, and it is proposed to purchase the spare parts for the original plant, which is safer and more secure in terms of production。
The cedritic cold water unit is developed and produced through a series of workflows whose work is highly accurate and well known. As a result, after problems with the cold water unit, the first call is made to the manufacturer (locally contracted maintenance department), who will come up with a solution and arrange for staff to go for repairs. Don't take it apart
4 how to maintain the cooler
In day-to-day use, the maintenance of chillers not only improves the efficiency of the chillers and their longevity, but also effectively reduces operational hazards and makes them more durable。
Maintenance of chillers:
Placing chillers in the cold of the ventilation is less than 40 degrees recommended。
2. Regular clean-up of cold-water condensers and dust-covering networks。
3. Periodically replace circulatory cooling water, and regularly wash tanks, usually three months before changing water。
4 the water quality and water temperature of the circulation water affect the life of the laser tube and it is recommended that deion water be used to keep water temperature at around 25°c。
5. The use of ultraviolet laser chillers is to keep the rooms clean and well ventilated and to regularly clean the condensers to ensure the normal operation of the units。
6. In case of failure of the crew, press the alarm stoppage button before checking the cause of the failure, bearing in mind that it is not forced to operate until the failure has been resolved。
7. Do not shut down the crew at will by cutting off power, if it is not an emergency; if the crew ceases to operate for a long period of time during the winter, the crew will be shut down before the main power source will be shut down and the water in the uv laser cooler will be purified。
5 cold water maintenance
It's better to find a place nearby where a lot of people do this。
Six, how do you fix it without water
In the case of inadequate water flows, cold water machines can generally be divided into two categories. First, there was a shortage of water flows at the beginning of use, because of the mismatch between the chiller pumps (because some lasers are strictly required for the flow and the length of the stretch or because cooling water is too long) and the need to replace the larger pumps. Second, cold-water machines could have been used normally, but there was a sudden lack of water flow, possibly due to water pump failure or congestion. At this point, the pipes can be removed and connected with air-pressure guns, and then connected to observe whether the chiller is functional or, if the cooler is functioning, because of the congestion of the water; if the cooler continues to have insufficient water flow, it is because of the failure of the chiller pumps, which can be replaced by a pump。
7 fault maintenance inspection of chillers
The details of the cedric cooler are as follows:
Step 1: the aim of the inspection of the findings of the cold water unit maintenance is to see if the chiller return team after maintenance has returned to its pre-response technical capability. Using the method of operating the units under different conditions of operation, a full assessment was made as to whether the repairs posed new problems to the chillers. Problems should be immediately corrected。
Step 2: the necessary acceptance tests for the cedritic cold water unit shall be carried out in accordance with the principles of pre-aeroclassified tests, post-vacuity tests, sub-tests, and post-corporate tests. Vacuum tests in lieu of vacuum pumps by compressors of the cold water unit itself are not permitted to damage compressors。
Step 3: in addition to checking the technical capabilities of cold water units, care must be taken to protect the integrity of the crew and the hygiene of the work site. The work site is to clean up, wipe out spilled oil, remove replaced parts and garbage, and finally remove tools and accessories, and not forget the tools or accessories in the cedley cold water unit or at the work site。
As the cooling temperature rises and the condensation pressure rises, it is not difficult to see that when cooling water towers spread poorly, the heat generated by water chillers cannot be removed as designed, directly leading to higher operating temperatures and lower refrigeration performance, which will have a direct impact on the water cooling machine performance factors and the service life

1. Reasons for the smell in a screwdriver
The so-called aphrodisiac, i. E., cooking materials and food in a screw colder, is influenced by external factors, and through changes in physico-chemicals, produces an abnormal odour, long and long, attached to the walls, roofs and tools of a screw colder. There's a stench in the screw cold, and there's usually a reason for this: there's a stench in the screw cold before the food。
Pre-scaling cold-water foods such as eggs, meat, fish, etc. Are corrupted。

9. Maintenance of the heli-cooler
The average cold-water machine has a life span of several years, and a spiral-type cold-water machine can be used for more than a decade. The normal maintenance is to wash the pumps over a period of time without affecting the quality of the frozen water. Professional maintenance requires their company to sell after-services, and it is best to stay calm。
