For cold water machines (especially sophisticated, high-value industrial equipment such as the long-flow instrument lx series) to be used for long periods of time, with fewer faults and three-part repairs, the seven-square diet is the absolute truth. Daily maintenance not only increases the lifetime (usually up to 5-10 years) but also ensures temperature accuracy control and prevents production from being disrupted by equipment failure。
The following is a guide for you on the maintenance of cold water units throughout their life cycle, divided into three dimensions of daily, regular and special attention:
I. Maintenance of the “pulmonary disease” core component (dispersion system)
The cold water machine is most afraid of the heat. Poor heat dispersion leads to a high load of compressors, the number one killer with shorter lifespans。
Wind-cold water cooler (cleaning wings):
The phenomenon: like home-based air conditioners, the condensers' wings fill with dust。
Maintenance: it is recommended that the dust net be cleaned every half month to one month. The dust on the condensers' wings is cleaned quarterly with compressed air guns or with a special fin wash。
Note: make sure that the machine is well ventilated and does not stack any groceries, leaving a distance of at least 1 metre in the vents and vents。
Water cooler (cleaning water):
Symptoms: if the water quality of the cooling towers is poor, the inner walls of the condenser copper pipe are susceptible to dirt, leading to high pressure alarms。
Maintenance: regular inspection of the water quality of cooling towers, annual “explosive” cleaning of condensers (physical or chemical defecation) to maintain heat exchange efficiency。
“diffusion” maintenance of circulatory blood (waterway systems)
The quality of water is the blood of the cooler. Poor water quality can lead to pipe congestion, reduced flow and even corrosive internal fluids of precision instruments。
Periodic change of water:
It is recommended that circulation water be replaced every three months. If the work environment is large, the frequency is higher。
Since you are concerned with the long-flow instrument lx series (support for high-clean water systems), you are advised to use pure or distilled water and to prohibit the use of running water or river water containing mud or rust。
Clean filter:
Waterway systems are usually equipped with y-type filters, which are removed and cleaned every month to prevent impurities from blocking water pumps。
Focus on ion consumption (for the lx series):
If your precision cold water machine selects a deion device, you need to regularly observe the conductivity data (the lx series colour screen can be shown). When the conductivity is higher than required, the ion resin must be replaced in a timely manner。
“checking” maintenance of electrical systems
Checking voltage currents:
Periodically observe whether the voltage and currents of the machine are stable at the time of operation, and whether they are within the scope of the signs. The absence of a picture or the unstable voltage can cause fatal harm to compressors (although the lx series has a gap/overload protection, there is still a risk of chronic exposure to severe grid environments)。
Tighten line end:
The machine operates with small vibrations, which can cause the end of the wire in the electric control box to loosen for long periods of time, causing poor contact or fire. It is recommended that every six months all wire screws be secured by professional electricians。
Iv. Seasonal and special landscape maintenance
Frozen winter (very important):
If the ambient temperature is below 0°c and the machine ceases to operate, the water in the pumps and pipes may swell with ice and freeze directly the shell of the pump or the inner pipe of the laser。
Measures: all internal waters must be drained at the time of shutdown; or an appropriate proportion of ethanol antifreeze should be added。
Using smart data (lx-series advantages):
The lx series you mentioned has historical data query and curve analysis functions。
Maintenance techniques: don't wait until it's broken. Regular (e. G. Weekly) movement of temperature and pressure curves. If the same cooling effect is found to have been achieved, but the pressure is increasing, or the temperature is volatile, this is when the device is “calling”, suggesting that you need to clean the condenser or check the refrigerant。
A simple summary of the “five-step maintenance” (suggested printing to be attached to the machine)
Periodic maintenance purpose:
Daily check for leaks, abnormal sounds, alarms for panels, and timely detection of minor problems。
The refrigerant pressure table values are checked weekly to keep the surface clean and ensure normal cooling systems。
Monthly cleaning of dust net/filter to check water tank levels, prevent heat dissipation and congestion。
Recycle water is replaced on a quarterly basis, condensers are washed (wind cold) and optimal energy efficiency is maintained (cop)。
Each year, circuits are checked for tightness, and a comprehensive systematic assessment is conducted to eliminate electrical hazards。
If you do so, your cooler will not only be able to spend more than a few years, but will also save you a considerable annual electricity cost due to the high heat efficiency。
