Method for cleaning vicarb heat exchanger plate

Vicarb heat exchanger plates have been widely used in some areas such as central heating and chemical industry. The plate heat exchanger has a good heat exchange effect, but it is prone to produce scale and impurities, which will block the flow of the plate heat exchanger and reduce the heat exchange effect. So, how to clean the plate heat exchanger?Plate heat exchangers can be disassembled and recirculated.

Disassembly and cleaning steps:
Disassembly and cleaning can clean both processes of the heat exchanger. The main steps are:
1. Close the two water inlet and outlet valves of the heat exchanger;

2. Measure the distance between the baffles of the heat exchanger and make a record;

3. Disassemble the plate heat exchanger, empty the medium in the equipment, disassemble in the prescribed order, and make a record. Be careful not to damage the gasket and the plate during the disassembly process;

4. During the cleaning process, the plates should be cleaned piece by piece, and soaked and washed. In the case of high-pressure cleaning, the cleaning should be performed below the specified pressure;

5. After processing, put it back in the plate heat exchanger baffle in the original order, paying attention to distinguish the front and back. Control the strength when tightening the clamping bolts firmly, otherwise it is easy to crush the plate;

6. Open the outlet valve and inlet valve of the plate heat exchanger to see if there is any leakage. If there is no leakage, the cleaning is complete.

Cycle cleaning steps:
If it is used in the chemical industry, firstly close the inlet and outlet valves of the plate heat exchanger, and add the cleaning agent to the system through a tube pump or a water tank for internal circulation until the concentration of the cleaning agent no longer changes and the impurities in the equipment are discharged.

If it is a passivation treatment, it is necessary to ensure that after the chemical descaling is completed, no rust or other phenomena will occur in the pipeline. The amount of passivation cleaning solution needs to be determined according to the amount of water during cleaning, and the ph value cannot be too high, otherwise the effect will be poor, and it will be discharged after six hours.

Finally, the plate heat exchanger was restored, and the inlet and outlet water valves were opened, indicating that the cleaning was completed.

How to take care of chinese synthetic cosplay wigs?

Friends who like cos know that taking care of chinese synthetic cosplay wigs and maintenance is the most headache. The magic cat shares some tips for wig care and maintenance.

Wig Cleaning
• Comb the hair neatly, otherwise it may damage the wig.
• Pour the shampoo into the water and stir well. Warm water at about 20 degrees is more suitable. Then soak the wig in the water for a few minutes and rub it gently. Rinse with water.
• Pour an appropriate amount of conditioner into warm water and stir, soak the wig in water for about ten minutes, and then rinse it with warm water.
• Shake off the water and dry it in a ventilated place.
• You can clean your hair after it is completely dry.

Precautions:
Chemical fiber hair: The water temperature should not be too high, it is not suitable for tools such as electric wind blowing, and it should not be exposed to the sun.
Real hair: hair dryer, hair net, synthetic fiber and real hair wig can be washed with detergent.

Many people don’t know how to arrange after wearing a wig, and random wigs make the wig messy.
• Buy a rubber ball and place it on the rubber ball.
• Find two wooden boards glued together, and put them on directly if you don't wear them.
• You can DIY a head model to place a wig.

Wig Care
• Try not to approach the high temperature when handling the wig, because most wig materials are not resistant to high temperature.
• The action when combing the wig should be light, comb the wig first and then wear it, you only need to organize it a little after putting it on. Generally, the combs used for wig care are relatively sparse, and the method of combing with oblique sides is more effective.
• In order to prevent the wig from falling, some friends will use a hairpin to clamp the wig, but be careful not to use too much force to avoid damage to the net cover.
• For longer wigs, comb the wigs into several lengths and comb from bottom to top.
• If the wig has been tied for a long time and it is difficult to comb, don't pull it hard, you should spray the non-oily maintenance liquid special for the wig, and then slowly open it.
• Use a special maintenance solution for wigs.

Can the indoor wifi camera work even when power is off?

UPS power supply is also called uninterruptible power supply as one of the basic components of an anti-theft alarm monitoring system. A system lacking backup power hides fatal flaws. It is very likely that the fighter will be lost at a critical moment, the anchor will be shut down, and the entire system will be paralyzed, causing uncompensable losses. The anti-theft alarm monitoring system normally uses 220 volts of mains power, and it should work normally for a period of time in special cases of power outages and damage to mains power.

When the mains power is normally input, the UPS will stabilize the mains power and supply it to the load. At the same time, the built-in battery pack will be charged to store energy in the battery. When the mains power is interrupted or the input fails, the UPS will immediately convert the energy of the built-in battery. Instantly continue to use 220 volt AC power for the load to keep the load working and protect the software and hardware of the load from damage.

UPS can be divided into two types of backup type and online type according to the working mode. According to its output waveform, it is divided into square wave output and sine wave output. Because the security monitoring system has high requirements for power supply, you must choose an online UPS power supply.

There are some details to pay attention to when configuring the UPS power for the monitoring system:
1. The interface is poorly matched, such as the audio and video connectors are tightly matched, please replace the connectors first.
2. The host is a card structure. Do not push or pull hard when the external connector is connected to avoid poor contact.
3. When the main unit is working, please fix the installation position and do not drag it randomly.

Surveillance camera maintenance
Regardless of whether it is a computer camera or a surveillance camera, pay attention to the following points in daily use and maintenance:
1. Try to avoid pointing the camera directly to the sun, so as not to damage the image sensing device of the camera.
2. Avoid contact between the camera and oil, steam, water vapor, moisture and dust, and direct contact with water.
3. Do not use harsh cleaning agents or organic solvents to wipe the camera.
4. Don't pull or twist the connecting cable. Similar actions may cause damage to the camera.
5. Unnecessary, do not disassemble the camera at will and try to touch its internal parts, which will easily cause damage to the wifi camera.
6. When storing, the camera should be stored in a clean and dry place.
