WHAT YOU NEED TO KNOW ABOUT USING STRING WOUND FILTER CARTRIDGE

String Wound Filter Cartridge is a more commonly used filter element in filters. People engaged in professional water treatment technology industries should be familiar with this product. The shelf life of wire wound filter elements is closely related to the application process. If used incorrectly, it will affect The life of the filter element and the interim effect.

1. The temperature of the filter medium; the frame of the wire-wound filter element is generally PP and stainless steel, and the material is also described in detail. The PP frame and PP material have the lowest temperature resistance.

2. The pressure of the filter medium; this is generally related to the filter frame. The PP frame has a low pressure resistance. The stainless steel frame has a high pressure resistance. When the pressure is low, it needs to be pressurized. Can be solved.

3. The diameter of the media particles to be filtered. The accuracy of the general wirewound filter is 1-100 microns. According to the media to be filtered, select the appropriate accuracy. If filtering the dirty water requires fine accuracy, it will inevitably lead to the use of the filter. The deadline is greatly affected, so everyone must clearly understand the diameter of the fine particles of the filtered medium in order to properly select the filtering accuracy.

4. The acidity and alkalinity of the filter medium; There are several materials for wire-wound filter elements; PP, absorbent cotton, and glass fiber. PP is more commonly used in water treatment technology. The key is to filter neutral or weakly acidic and alkaline liquids, absorbent cotton and glass. Fiber can also filter strong acids and alkalis.

Under what circumstances does Honda GX190 carburetor need adjustment

In the case of a plunger Honda GX190 carburetor, if the exhaust pipe emits black smoke or unstable idle speed, the throttle is not smooth, and the transition is poor, then the carburetor needs to be adjusted and cleaned at this time.
      After some repairs to the vehicle, the mix ratio is also readjusted, and then the idle speed is readjusted. For example, after adjusting the valve clearance, the mixing ratio needs to be readjusted.

      Which repairs will cause the valve clearance to change? Replace the car of the piston ring, replace the rocker arm of the cam. These must be removed. Then adjust the valve clearance. After adjusting the valve clearance, we need to mix the carburetor. Than the screw to adjust.

      Another point is that if the air filter element is too dirty, it needs to be adjusted again after cleaning the filter element, so that the carburetor can achieve a better working condition.

      If the fuel consumption is adjusted, the oil level can be reduced a little. This is a more elaborate technical activity, and it is generally not recommended for non-professional friends to try to adjust. So as not to cause unnecessary trouble.

     Plunger carburetor, when it is colder in winter. Especially in this frosty weather, some carburetor may appear to be flying. Most of the reasons are because the plunger gap is too small, resulting in the formation of fine ice, which cannot be returned flexibly. We can take out the plunger and use fine sandpaper to apply clean engine oil, polish the plunger again, and then apply a thin layer of engine oil. If this is done, there will be occasional overspeeding. Carburetor quality problem, need to replace the carburetor. Safety comes first.

 

 

CAR GEARBOX MISUNDERSTANDING

What are the taboos of using a Gearbox in a car? What driving behaviors can easily damage the transmission and cause it to malfunction?

Some car owners mistakenly believe that N-speed taxiing can save fuel. In fact, this method is very unsafe and does not save fuel at all. This operation can easily cause damage to the gearbox. When engaged in the N gear, the gearbox oil pump cannot lubricate the engine oil. This will cause the gearbox-related parts to generate high temperatures, which will increase gear wear. In the long term, the gearbox is easily damaged.

Each forward gear of the automatic transmission has a maximum speed limit. If the transmission is forced to a low gear in a high gear, it is easy to damage the clutch plate in the gear.

After the car travels a certain mileage, the gearbox oil must be changed in time. The frequency of the automatic transmission and manual transmission is different. Problems will easily occur regardless of the long time. Transmission oil will deteriorate and volatilize under high speed and high temperature for a long time, which will increase the wear of mechanical parts and may even damage internal parts of the transmission.

Causes Of Color Cast On Analog CCTV Surveillance Camera

1.Camera Imaging
The spectral power distribution is a central wavelength of 830-950nm and a half-peak bandwidth of about 40nm. It is a narrow-band distribution in the near-infrared spectral band and is a range that can be felt by ordinary CCD and CMOS. In this way, real-time monitoring can be performed during the day or at night.
Since any object above absolute zero (-273 ° C) emits infrared light, during the daytime, the CCD or CMOS senses both visible and infrared light. The longer the wavelength, the smaller the refractive index; the shorter the wavelength, the larger the refractive index.
Therefore, when these rays enter the camera lens at the same time and are refracted by the lens lens, visible light and infrared light will be imaged on different target surfaces, while visible light is imaged as a color image and infrared light is imaged as a grayscale image. The resulting image is well adjusted. At this time, infrared light will form a virtual image on this target surface, which will affect the color and quality of the image.

2.Single filter
The filter filters out infrared rays while trimming the light and restoring the true colors of the image. Therefore, it is impossible to image without visible light at night, that is, there is no night vision function. In order to solve this problem, Ao Shuo developed and applied a single peak filter with a double peak height. This camera has a night vision function.
This single filter is low in cost and can be used in both day and night. Due to the opening of the wavelength frequency, the light in the natural world during the day contains more infrared light, and some of it can also enter the CCD or CMOS and interfere with the color reproduction of the image. For example, green plants become gray and black becomes purple.

If the effects of day and night are to be considered comprehensively, it is difficult to completely adapt the graph of the filter. In the daytime, some infrared light still interferes with the color reproduction of the image; at night, due to the filtering effect of the double-peak glass sheet, the CCD or CMOS cannot make full use of all the light, resulting in snow spots, and reducing the image clarity and low-light performance of infrared cameras .
Incorrect installation will also cause the camera to be discolored. For example, take two infrared cameras with better infrared shooting, or take four lights to test in a small box. The image will appear light purple. Switching mode is normal. The camera first has a photoresistor to sense the illuminance, first turn on the infrared light, and then switch the IR-CUT. When the small box is tested, the infrared light is on, but the IRCUT is not switched (equivalent to the day mode), the infrared light is reflected, and it may look light purple.

Maintenance measures for Hydraulic hose

There are tens of thousands of causes for failure of hydraulic hoses, and failures can generally be reduced by appropriate precautions. Pay attention to fluid compatibility. Incompatible fluids may cause the inner rubber layer of the hose assembly to deteriorate, swell, and delaminate. The hose must be compatible with the fluid being transported to ensure that the fluid is compatible with the inner rubber layer.

Dry air, the inner rubber layer of the hose may cause tiny cracks due to the dry air. This type of failure is difficult to detect, the hose remains flexible, but there are signs of external leakage. For this problem, make sure that the hose rating is suitable for extremely dry air.

Minimum bend radius. In vacuum and suction applications, if the bend radius is exceeded, the hose may become flat in the bend area. This may lead to obstruction and restriction of the flow of the medium, and if the bend is too severe, the hose is likely to kinked. To prevent failure of the minimum bend radius hose, the recommended bend radius should be carefully checked.

Worn, hydraulic hoses are subject to harsh environments every day, and their effects will eventually show up on the hoses. Hydraulic rubber hoseexporter Properly assembled and installed hoses can extend service life, thereby reducing downtime and maintenance costs.
