Poor equipment use environment. If equipment is used improperly and maintenance is not done in time, it will inevitably accelerate the aging of the equipment. For example, if the external watch is not protected, it will accumulate dirt, damage the paint coating, and make the instrument quickly rust and worn out. Failure to pay attention to moisture-proof and heat-proof will reduce the insulation strength of internal circuit components, wiring, and brackets, resulting in serious faults such as leakage, change of value, breakdown, and burnout. Therefore, in the production practice, well logging equipment should be used to prolong the life of logging equipment. The maintenance and maintenance of logging equipment is especially important.
The simplest overhaul of sensors and circuits is the maintenance personnel's use of eyes to see, listen to the ear, to visually determine whether the components are damaged and the location of the fault, determine the cause of the fault, the advantage is simple and rapid, does not require the use of professional detection instruments, this method should have With certain experience, this method is often used to overhaul initial failures and improve ergonomics.
There is measurement and maintenance, through the multimeter to measure the voltage, current, resistance to determine the fault, the general need to measure the product power supply voltage and the unit voltage of each unit operating point voltage crystal extreme voltage, the voltage of the integrated block pins, and The normal value is compared to analyze the cause of the fault. By measuring the whole machine or unit circuit operating current, the sensor input signal current to check for short circuit, component damage and the working status is normal. Because the current measurement needs to connect the current meter into the line, it is often necessary to disconnect the component wiring in the printed circuit board or the line, and sometimes the operation is inconvenient, so it is also possible to indirectly measure the electric voltage and convert the current value again using Ohm's law. The measurement of resistance is often used in the case where the machine to be repaired is not energized. It is also a simple method to judge the quality of a component when it is connected to contacts, contact pins, and printed boards.
Then there are some products because of the bad use of the environment, the components are subject to vibration, corrosion, oxidation, wear, dust caused by displacement, poor contact moisture, so that the whole machine is not working properly, resulting in reduced technical performance, can be printed on the board, components Such as dust, with non-corrosive anhydrous alcohol, such as cleaning, and then dry or dry, remove the oxide joints re-welded joints, reinforcement fasteners, thereby restoring product features.
During the normal use of the UPS, the equipment should be frequently maintained and maintained to ensure reliable operation and extend the life of the equipment. Should always pay attention to make:
Ensure that the UPS is clean and free from dust and foreign objects. When turning off the UPS, wipe it with a soft, dry cloth.
In areas where there is no power interruption for a long period of time, disconnect the UPS mains input periodically (usually for three months), discharge the battery by 30%, and check the battery operation.
our mainly products are filter drier, replaceable filter drier, oil separator, suction line accumulator, liquid receive, pressure hose ,valves and other refrigeration parts.
