New for Cheng Technology Co., Ltd. introduced a new series of economical miniature vacuum pump VAT, many new and old customers are very interested, have called to show strong desire to buy. However, we need to remind everyone that the economy, although the price is cheap, but it is impossible to replace our other high-end miniature vacuum pump. VAT is essentially a miniature vacuum pump VLK economical products, the specific differences between the two are as follows: 1. Different functions: VLK brushless vacuum pump series, using imported high-grade brushless speed motor, built-in control circuit, PWM speed, FG Motor feedback, with PLC control circuit, etc., can form closed-loop control, very convenient to adjust the motor speed, thus further adjust the flow, negative pressure and other parameters, to complete the constant current, constant pressure and other advanced applications; Speed ​​does not stop. The economical vacuum pump VAT series, there is no such function, can only have a great limit of the voltage regulator or valve flow, and the adjustable range is very narrow, with a large gap between load capacity and VLK. 2. The quality is different: The manufacturing cost determines the quality is quite different. For example, the VAT adopts the oil bearing and the VLK series of long-life vacuum pump. It adopts the high-grade double ball bearing with continuous running performance and stability under heavy load Degree, reliability, etc. vary greatly. 3. Anti-jamming performance: the use of high-grade imported brushless motor brushless vacuum pump VLK series, run-time basic no electromagnetic interference, will not cause the control circuit and other crashes, and economic miniature vacuum pump VAT, etc., may have a larger operation Spike voltage, conduction through the power, easily lead to control circuits, LCD screens and other crashes. 4. Different noise: VLK can run day and night, the middle of the basic no change in noise; and VAT continuous operation for a period of time, due to the oil bearing oil is gradually being dried, etc., may lead to noise becomes very large ... ... 5. Different life expectancy: The actual long-term continuous operating time of the VLK at full load is> 6000 hours and the test is still ongoing; and the VAT has a continuous operating life of only about 1000 hours. 6. Warranty different: brushless vacuum pump VLK series warranty for one year, and economic products warranty for six months. ... ... The above analysis, sufficient to illustrate that in the selection of miniature vacuum pump, you can not just focus on costs, but should take into account the customer's own quality, reliability and other needs in order to select the most suitable equipment for miniature vacuum pump. "New for honesty", specializing in the field of micro-pump ... ...
Cylinder Ceiling Light
We diviided the led light according to the using eviiroment. Most of our product is the commercial LED Lighting
Commercial lighting is a term used to describe lighting that is used in commercial spaces, including auto dealerships, distribution centers, churches, factories, offices, and warehouses. Unlike residential lighting, commercial lighting is made to withstand more abuse and has a longer lifespan.
While the focus of residential lighting is often on aesthetics, commercial lighting is task orientated. Commercial lighting systems are designed based on what the application is. For example, in an office-type setting, you may see task lighting, which illuminates specific areas where employees need concentrated light to be able to perform their jobs.
