Is there no warranty for water intake? 200

It must have been repaired at your own expense. Maybe there is not much water ingress, not to the point of changing the motherboard. Just repair the power supply chip. You can wait for him to ** and inform the warranty time before deciding.

Are you talking about the Xiaomi sh phone? The mobile phone warranty card has a warranty scope and warranty time limit. If the mobile phone is flooded, do you see that it is within the service scope of the warranty card? Even if there is no warranty, what he said is that there is no free warranty, and you can spend money on repairs.

Xiaomi Mi 10 water ingress is a human factor, non-quality problems are of course not warranted, can only be repaired for a fee.

Even if any mobile phone claims to be waterproof, there is no warranty for water ingress, and you need to pay for repairs yourself, of course, there may be professional-grade water draining equipment that is warranted.

Water ingress into the mobile phone is a personal behavior that causes the mobile phone to be damaged, which is not covered by the warranty, and the cost of replacing the motherboard is very high, how much does it cost to repair, and the customer service will inform you in advance before the repair.

Go to Mi Home or a designated repair point to detect which hardware damage needs to be replaced. Look again**. If it exceeds 60% of the current price, I don't think there is any need for repairs.

If your phone gets into the water, then as long as you still have that warranty card in your hand and the warranty card has not expired, then you can carry out the warranty.

All mobile phones that are not repaired by water are the same, and the first thing to do when water enters is to turn off the phone immediately, and then take it to the mobile phone store to dry.

It is possible to contact people on the network for repairs, and repairs are worth it.

If the mobile phone accidentally gets into the water, you can try the following ways to deal with the mobile phone urgently to avoid secondary injury:

1. Please take the mobile phone to a dry and ventilated place as soon as possible, and use a dry paper towel or towel to blot the water stains on the surface of the mobile phone.

2. If the phone is turned on, press the power button to turn it off; If your phone is turned off, don't try to turn it on.

3. Please remove the SIM card and microSD card as soon as possible.

4. Please bring your mobile phone to the after-sales department of the mobile phone brand for testing and processing as soon as possible to avoid unnecessary losses.

2. Please do not bake with a hair dryer or stove after water ingress, so as to avoid liquid flowing into the inside of the mobile phone and damaging the mobile phone at high temperatures.

3. Some mobile phones can be turned on and used normally after simple treatment, but the mobile phone is composed of precision electronic components, and there is a hidden risk after water ingress, so it is recommended not to try to turn it on.

4. During the after-sales maintenance process, the data may be lost, it is recommended to ask the staff how to back up the data, and the specific after-sales maintenance cost is subject to the staff notice.

If you leave it overnight, it will get water. Here's why:

1. The waterproof depth of the watch does not represent its waterproof power in the corresponding water level.

A watch that is water-resistant means that the watch can only come into contact with living water, wash your face, brush your teeth, and wash vegetables. If you immerse yourself in water, such as bathing or swimming, you may get water into your watch.

So the 10-meter water resistance watch will definitely enter the water if it is left in shallow water overnight.

Note that no matter what waterproof watch, it is only waterproof, not waterproof vapor, water vapor into the dial, will corrode the movement, water vapor into the inside will destroy the lubrication inside.

The 50-meter water resistance watch can be taken off for bathing and swimming. However, it should not be soaked in water for a long time.

Friend, the number of meters of water resistance of the watch is not calculated according to the depth of the water. For example, when you say a 10-meter water-resistant watch, you don't mean that it won't enter water at a depth of more than 10 meters. In addition, the general watch water resistance rating, I have only heard of rice water resistance, etc.

10 meters is the first time. As far as I know, the greater the waterproof meter, the stronger the waterproof ability. 30-meter water resistance refers to the general daily life waterproof.

For example, washing hands, light rain, water vapor caused by alternating hot and cold inside and outside the house in winter, etc. However, it is not recommended to take a bath and wear it, not for swimming, and even more so for diving.

To sum up, your 10-meter water resistance can be imagined.

Hope mine solves your problem. Thank you!!!

The watch is water-resistant.

Generally, the waterproof standards of watches are divided into: 30 meters, 50 meters, 100 meters, 300 meters, and 500 meters. The depth of water resistance does not refer to the depth in the water, but the pressure.

3ATM: 30-meter water resistance, waterproof for general life, water droplets splashed when washing hands, and raindrops falling when it rains lightly. However, care should not be taken for too long, let alone in the sauna;

5atm: 50-meter water resistance, enhanced lifestyle. Can be wiped with a small amount of cold water;

10atm: 100-meter water resistance, you can wear a watch for car washing and showering activities, but you can't soak in water;

30atm: 300-meter water resistance, suitable for swimming activities, but only suitable for light swimming. Do not interpret this as being in 300 meters deep water;

50atm: 500-meter water resistance, can be used for diving sports. At a depth of one or two hundred meters, it is not recommended to dive deeper.

The waterproof of the watch depends on the waterproof rubber ring on the glass, back cover, handle, etc. to meet the corresponding standards. All waterproof watches are marked with the words "water resistant" or "water proof" on the case back, and watches without waterproof marks are only dustproof and should be protected from water.

Precautions: 1. Do not swim with a 30m watch;

2. Do not wear any watch to the bathhouse, do not wear any watch to sauna;

3. The watch should be maintained every 3-4 years or so, and the waterproof test should be carried out;

4. If the watch is flooded, it should be dealt with in time, and it needs to be scrubbed and maintained by the watch maintenance institution. If the watch is not repaired in time, then the water will make the steel parts in the watch movement appear embroidery, and the tiny clock parts usually need to be replaced once rusted, in addition to the movement parts, long-term contact with water vapor will also make the watch dial, blistering and rust occur.

The water-resistant specifications of mechanical men's watches are divided into the following types: 30 meters, 50 meters, 100 meters, 300 meters, and 500 meters.

30 meters: refers to the general life waterproof, that is, when washing hands splashed with the plum blossom men's watch mechanical droplets, as well as the raindrops that fall when it rains lightly, but pay attention not to be too long, do not wear the plum blossom gold-plated men's watch in the sauna.

50 meters: There is no difference between 30 meters and can be ignored.

100 meters: You can take him to wash the car and shower, but not to soak in the water.

300m: Swimming is possible, but only for shallow swimming. (Don't take it as if it's at 300 meters.)

500 meters: This level can be submerged, if I remember correctly, that is, left and right, there may be more, but don't do it according to the established value, maybe that's the limit of what your watch can bear, so don't test the performance of the watch in this way.

At last. Don't understand the waterproof depth as the depth in the water, everyone is right about the pressure, but the rest is not right, also, these are for the steel band, plastic, rubber strap of the watch, if the leather strap does not let him stand even a little bit of water, including your sweat!

Additional note: At present, any waterproof watch, whether it is marked as xx meter proof, cannot be used in hot water.

There are two reasons for this: the permeability of water molecules is greatly enhanced in the presence of increased temperatures, and all waterproof watches are designed based on cold water. Depending on the thermal expansion and contraction, some components of the watch will expand to varying degrees under hot water conditions, resulting in the possible increase of the gap.

After the mobile phone falls into the water, I believe that the first reaction is to fish out the mobile phone as soon as possible, which is also very important, reducing the time of contact between the mobile phone and the water, which will minimize the damage to the mobile phone. The longer the time in the water, the greater the damage to the phone's earpiece, microphone screen and motherboard, wipe the phone out of the water and dry it quickly, and remember not to try to turn on the phone without water on the surface.

Many users will subconsciously press the power button after taking out the mobile phone to see if the mobile phone can still be turned on, which is very wrong, so that even if the mobile phone itself is not damaged, once it is turned on, it may cause the result of burning the motherboard.

IP67 rating, can insist on 30 minutes of waterproof at a depth of 1 meter, and PUW waterproof membrane can last for 1 week at a depth of 10 meters.

PUW waterproof membrane function:

1. Waterproof, dustproof, oil-proof, protection level up to IP68.

2. Chemical resistance, high and low temperature resistance, anti-aging, etc., to improve the reliability of the product in harsh environments.

3. Prevent condensation and fogging, and improve the service life of the product.

4. Micro-heat dissipation and balance pressure difference. Improve product integrity.

The landlord needs to know how long IP67 can last at a water depth of 10m, which depends on what kind of product it is.

For example: an electronic watch, waterproof is IP67 water, water depth 1m, 30 minutes to retrieve, can work normally, no water, but you take it back in 31 minutes, the watch can not work normally, has entered the water, what can this mean? The watch complies with IP67, but is related to the immersion time; If it is a connector (plastic molding), the waterproof level is IP67, the test condition is 1m water depth for 30 minutes to confirm that there is no water ingress, when you put it to 10m water depth, it may also be able to support 30 minutes, or it may only be 1 second, there is no way to confirm, because the grade of this product you confirm is IP67 so different requirements, the test conditions are different, or you can set IP68, the requirement is 10m water depth for 30 minutes, if you meet this level, then the product meets your requirements.

It can give you an experience, the higher the density of the part body, the better the waterproof performance, if there is air inside the part, there is basically no need to test IP67, put it into 10m water depth, 1 second can not hold; If it is a nylon material, it is not good, and the molecular structure itself is absorbent; If it is a PVC material, it is slightly better, and if it is filled with high-density silicone water, this one will be a little better.

Obviously it's negatively correlated, you this math.

There is no standard for this, and it is normal for water to enter in 1 second.

For all centrifugal pumps, the maximum water absorption height is 5 6 meters.

Right (theoretically meters), the self-priming pump is also a centrifugal water pump. Suction lift refers to the vertical distance from the moving water level to the center line of the pump shaft, note: this refers to the moving water level, not the static water level:

The static water level is the vertical distance from the water surface to the ground when the water is not pumped, and the moving water level is the vertical distance from the water surface to the ground when the water is pumped non-stop.

The self-priming of the self-priming pump means that the water pump does not need to fill the inlet pipe with water (exhaust air) when it is started, and it has nothing to do with the suction stroke, and there is no centrifugal pump with a suction stroke of 10 meters. So, if the moving water level of the well is less than 5 or 6 meters, the water can be pumped. Otherwise, only submersible electric pumps can be used, or the installation position of the pump can be lowered.

How high is the water surface from the ground in vertical calculations?

With a small pump.

The principle of operation is that the liquid gains energy under the action of inertial centrifugal force to increase the pressure by relying on an impeller that rotates at high speed. Before the pump works, the pump body and inlet pipe must be filled with water to prevent cavitation.

When the impeller rotates rapidly, the blades cause the water to rotate quickly, and the rotating water flies away from the impeller under the action of centrifugal force, and the water in the pump is thrown out, and the central part of the impeller forms a vacuum area. The water from the source is pressed through the pipe network under atmospheric pressure (or water pressure) into the inlet pipe. In this way, continuous pumping is possible.

The pressurized water well is not installed with a pump more than 10 meters to lift water, depending on the conditions of your existing wellhead

1. What kind of power can be used to lift water? Manpower, electricity, wind power?

2. How big is the wellhead and how large is the diameter of the water lifting equipment that can be installed at the wellhead;

3. Whether you plan to use water continuously or intermittently, and how much water you use.

You can add a piston in the middle of the well and relay the water to carry it.

Dear users, hello!

This is the Lenovo FAQ knowledge base, which has a relatively complete answer and know the process and analysis:

Ground water refers to the water that exists in the rock voids below the ground, and in a narrow sense, it refers to the water in the saturated aquifer below the groundwater surface. In the national standard "Hydrogeological Terminology" (GB T 14157-93), groundwater refers to various forms of gravity water buried below the surface.

Foreign scholars believe that there are three definitions of groundwater: one refers to all the water buried in groundwater that is significantly different from surface water, especially the part of water in the saturated zone of the aquifer; the second is to flow downwards or infiltrate to saturate the soil and rocks and replenish water from springs and wells; The third is the water stored in the rocky cavities in the ground, in the voids that make up the earth's crustal material.

According to the definition of groundwater, as long as the sinking well touches the diving surface, it is considered groundwater! As long as the local diving surface water level is exposed, it is considered groundwater! Therefore, water within 10 meters is considered groundwater!
