Brandt VSM300 Scalping Shaker Screen
Brandt VSM 300 Scalping Shaker Screen
SJ-Brandt VSM 300 Scalping shaker screen is manufactured as the replacement screen for Brandt VSM 300 shale shaker. It is installed on the top deck of the VSM 300, which are used to scalp off large volumes of solids. Thus protecting the finer mesh , The scalping screen is usually sized from API 10 to API 325, ShengJia promises you high quality VSM 300 screen at reasonable price. And there are steel frame and composite screens optional.

First of all, aging is an important guarantee for the reliability of LED electronic display products. It is also a procedure that must be followed after each display is completed. If there is no aging display, no matter whether it is indoor or outdoor or monochrome, dual-color or full-color. Are all unqualified products. LED products can improve performance after aging, and help stabilize the performance of later use.
Aging test is a very important part in product quality control, but it is often overlooked in many cases and cannot be correctly and effectively aged. The LED aging test is based on the product's failure rate curve, that is, the bathtub curve characteristics, to improve product reliability.
Second, LED aging methods include constant-current aging and constant-voltage aging.
1. A constant current source means that the current is constant at all times. There is a frequency problem, it is not constant. That is AC or pulsating current. AC or pulsating current sources can be designed to have a constant effective value, but this source cannot be called a constant current source. Constant current aging is the most consistent LED current operating characteristics, and is the most scientific LED aging method;
2. Overcurrent shock aging is also a kind of aging method newly adopted by the manufacturer. Through the use of adjustable frequency, current adjustable constant current source for such aging, to judge the quality life expectancy of LED in a short time, and can be singled out Many conventional aging cannot eliminate the hidden dangers.
Finally, the following items to note during the aging test are as follows:
1. The display aging test must be attended by people and problems should be reported to the engineering department manager for processing.
2, monochrome, grayscale gradient test is not less than 48 hours.
3, the display screen test time of not less than 48 hours.
4, video, text effect test is not less than 48 hours.
5, test content: white screen, red, green, blue, monochrome, gray gradient, video effects, text effects.
