World AIDS Day 2022

 

World AIDS Day is observed on December 1 each year. This is a day for people worldwide to unite in the fight against HIV. Getting tested for HIV is the only way to find out if you are infected.

 

Accurate screening of HIV patients

Because AIDS has a long incubation period, many patients are still healthy after infection, accompanied by mild symptoms or no symptoms, it is likely to lead to HIV transmission to others, with lifelong infectivity. Therefore, how to make a clear diagnosis of AIDS in a short time and screen out HIV carriers is the main method to control the spread and development of AIDS at present.

Nowadays, HIV infection is mainly diagnosed by HIV antibody detection method. In addition to enzyme-linked immunoassay method, rapid test, which has the characteristics of simple operation, convenience, fast detection speed and high sensitivity, has also been widely used in clinical practice in order to better screening.

Operation precautions and maintenance methods of magnetic pump

 

I.Preparation work before operation of magnetic pump.

1. Check whether the bolts and connectors are loose, and tighten if they are loose.
2. Use the hand disc to move the coupling to make the pump rotor rotate several times to see whether the rotation is flexible and whether there is a sense of noise or uneven weight, so as to judge whether there is a foreign body in the pump.

II. Start-up procedure of magnetic pump.

1. Open the suction valve, close the relief valve, pressure gauge valve, vacuum gauge valve, and pump.
2. Open the discharge valve slightly, start the motor, and check the motor steering (clockwise from the direction of the motor).
3. After turning correctly, start the motor and open the pressure gauge and vacuum gauge valve.
4. After the pressure rises and thinks that the machine is running stably, slowly open the discharge valve and the pump works normally.
5. Pump operating point should float up and down at the operating point, too small, too large flow are easy to cause pump damage.

III. Matters needing attention in the operation of magnetic pump.

1. No-load operation of the pump is never allowed. Once the liquid is cut off or there is friction in the pump, stop running and switch the pump to prevent further damage caused by the pump no-load.
2. If there is a medium that is easy to solidify in the pump, steam must be passed before start-up, and only after the medium is fully dissolved can you start the operation.
3. In the trial operation of the magnetic pump, it is necessary to check whether the whole system has air leakage, liquid leakage, performance meets the requirements, whether the unit has large vibration and abnormal noise, it can be put into operation only after it is considered qualified in all aspects.

IV. maintenance and maintenance of magnetic pump.

The magnetic pump must do a good job of daily maintenance and maintenance in order to effectively give full play to the good performance of the pump and prolong the service life of the pump. a. Monitoring and maintenance in operation.

During the operation of the pump, it is necessary to strengthen the inspection of the unit, find the anomaly as soon as possible and deal with it as soon as possible. In general, during the inspection, we should pay attention to the following aspects at all times:

1. Pay attention to whether the sound and vibration of the unit are normal.
2. Observe whether the meter readings such as ammeter, power meter, pressure gauge, vacuum meter and flow meter are normal.
3. Pay attention to whether the pipeline is leaking gas, liquid, etc.
4. Usually keep the unit clean and pay attention to the safe operation.

V. Maintenance after operation.

1. In the cold season, especially in the outdoor pump, the liquid in the pump should be removed immediately after stopping to prevent freezing.
2. The general spare pump should also be started regularly.
3. Regular maintenance of magnetic pump, check and replace unqualified vulnerable parts, such as bearings, bushings, thrust rings, etc.

How to make a good pickleball paddle

 

A qualified Pickleball paddle needs to go through a series of sophisticated production processes to be produced. Carbon fiber Pickleball paddle is one of them, which has high requirements on the production process. Therefore, every step of the production process needs to pass a qualified inspection. To ensure that the racket produced is satisfactory to customers.

  we are manufacturing the materials for our products by our own, therefore we have the confidence in the materials that we use for our products. Besides that, we need to use carbon fiber to do some lay-up and make the shape of product before molding. For molding part, we use high temperature molding 150℃ under 100 tons of pressure to complete the molding process in order to make the shape and construction of products are stable and great. Furthermore, there are some significant production processes need to be done to ensure that the products performance as good as we expect.

  The pictures below will help you understand the pickleball production process in more detail.

Understand The Basic Parameters Of LED Lighting Products

Understand the basic parameters of LED lighting products

When we choose or purchase lamps, we often pay attention to the relevant parameters of the lamps, such as: brightness, life, color temperature, etc., as a standard to distinguish the advantages and disadvantages of the lamps. But do you know enough about the parameters of the lamps? Here is an explanation of the common parameters for the majority of buyers, so that everyone can choose their favorite LED lighting fixtures when buying.

1. Brightness
The brightness of the LED light is the parameter that users care about most, and the brightness can be explained from two aspects.
Luminance L: The luminous flux per unit solid angle per unit area of the luminous body in a specific direction. Unit: Nit (cd/㎡).
Flux φ: The total amount of light emitted by the luminous body per second. Unit: Lumens (Lm), which means how much the luminous body emits light. The more luminous the light, the greater the number of lumens.

2. Lifespan
The life of lamps is usually related to quality, and the difference in quality is the key to the length of life. Life is determined by light decay. LED products usually do not fail suddenly, but the light output will decrease over time. The usual practice is to measure the lifetime from a 30% reduction in output (that is, 70% of the remaining light output). This is commonly referred to as "L70 life" and is measured in hours.

3. Wavelength
LEDs of the same wavelength have the same color. The spectral wavelength distribution of several commonly used ultra-bright LED lights is 460～636nm, and the wavelengths appear from short to long as blue, green, yellow-green, yellow, yellow-orange, and red. Typical peaks of common LEDs of several colors The wavelengths are: blue-470nm, blue-green-505nm, green-525nm, yellow-590nm, orange-615nm, red-625nm.

4. Color temperature
The color temperature of a light source is defined as the Kelvin temperature of a black body radiator that emits light similar to this light source. Color temperature is the unit of measurement to identify the color of light, that is, the K value. Yellow is "below 3300K", white is "5300K and above", and intermediate colors are "3300K-5300K". Customers can choose the appropriate color temperature of the light source according to their own preferences and the needs of the environment.

Of course, the parameters of LED lights are more than these. For example, strobe, heat dissipation, light efficiency, etc. are all relevant parameters for judging the quality of LED lights.

There are also many applications for led lights, such as outdoor fixed led display, and outdoor fixed large-scale digital signage can be used in various advertising venues, such as stadium video review, dozens of storey shopping malls, etc. There are also many applications such as led solar flood light and so on.
