Good Job Sir! Thank you for sharing your hard work with us! -

I got the same anti-virus (McAfee) on both computers, indeed, but that sounds unlikely due to the fact that it worked without any problem BEFORE that I created the shortcut, and that I don't get any message of any kind (while there is such a message when a software is blocked by McFee or by Windows Defender... in general). Update: Same behavior (flashing flash screen then nothing) when I disable the Real-Time Scanning from McAfee. -
The three-leaf roots fan is beautiful in appearance, compact in structure, and well manufactured. At present, it is a new energy-saving and efficient product in China. The gear has a five-grade hard tooth surface with high precision. The three-blade roots fan runs six times a week, with high volume efficiency. Simple structure, easy to use and maintenance, no internal lubrication, no oil in the medium. The support of the pump rotor USES a reliable clearance structure, the rotating parts for careful dynamic balance, and the use of high precision helical gear, therefore, smooth operation, low noise, use more reliable, can be in the high pressure difference for a long time. The dynamic sealing part adopts the imported patented technology, and adopts the imported oil seal, and the pulsating quantity of the control shaft seal is less than 0.01mm. The old roots fan, no matter two-bladed, three-bladed, its compression principle is: the rotor blower bearing imported from Japan NSK bearing. There are two lubrication methods: grease lubrication is used below 0.6kgf/cm2, oil splash lubrication is used between 0.7-0.9kgf/cm2 to make the product quality more reliable. When the end opens to the exhaust outlet, the high-pressure air in the exhaust outlet is counter-current to the housing for compression. This countercurrent and compression produce dramatic pressure changes. This pressure change causes the fan noise. In order to eliminate this factor, the spiral shape of three-blade roots fan is studied. Roots blower flow, wind pressure, power is completely different from the centrifugal fan, the flow of the fan generally does not change much, the pressure change range is larger, when the pressure increases, the shaft power increases; When the pressure of centrifugal fan increases, the shaft power decreases. The three-leaf roots fan is superior to the two-leaf roots fan in performance. The factory introduces the international advanced involute outer arc inner cycloidal composite line, high manufacturing precision, high efficiency and energy saving in the domestic leading level; Low noise, high efficiency, easy to operate, maintenance-free. The output air is clean, free of any oil and dust, and the fan has a reasonable sealing structure, so that the oil cannot enter the casing, so the air is clean. The three-blade roots fan, whose air volume is about 40m3/min, belongs to a small fan, roots fan should be enough to use, and the centrifuge can only show its advantage in energy consumption above 100m3/min. Roots is more practical in terms of both price and energy consumption in terms of small flow.

Chemical industry suitable for water ring vacuum pump The only way to solve the cavitation problem of vacuum pump in high vacuum state is to try to improve the use environment of water ring vacuum, the temperature of circulating water, the temperature of suction gas and other external conditions, so as to reduce the cavitation of water ring vacuum pump. In view of the manufacturing accuracy of water ring vacuum pump, this problem is mainly the understanding and improvement of the design capacity and production and processing accuracy of the water ring vacuum pump manufacturer, which is also a test of the production capacity of the water ring vacuum pump manufacturer. The single-stage water ring vacuum pump can not meet the production requirements, and the unit cost is too high. The traditional 2SK water ring vacuum pump has many disadvantages. Aiming at various reasons, the multi-stage water ring vacuum pump is designed. Under the high vacuum state, the efficiency is more than 20% higher than the single-stage pump, and the performance is more stable than the 2SK water ring vacuum pump, which is suitable for various chemical industries. In order to improve the air volume of water ring vacuum pump in high vacuum, reduce the noise caused by cavitation erosion, and reduce the damage of cavitation to the internal parts of vacuum pump, a new type of high-efficiency air ejector is specially designed, which is 30% more efficient than the traditional air ejector, and can be used together with water ring vacuum pump to ensure that the air volume of water ring vacuum pump in high real state reaches 75% of the standard air volume Above. In the long-term cooperation with customers, the vacuum pump mall has also invested a lot of manpower, material resources and energy to help customers solve "difficult problems". In particular, environmental protection issues, and then the water ring vacuum pump and environmental protection equipment are closely linked. Therefore, the vacuum environmental protection waste liquid treatment system is designed, 100% of which adopts physical environmental protection treatment method to eliminate secondary pollution. 2BV2 061 Water Ring Vacuum Pump Two Stage Rotary Vane Vacuum Pump In Vacuum Precooling How To Solve Screw Vacuum Pump Not Start

The goal of this project is to utilize an MSP430 to allow existing remote-controlled outlets to by controlled over Wi-Fi. As purchased, the outlets can be controlled with a provided remote control which uses 434 MHz radio signals. By programing the MSP430 to replicate the signals from this remote and hosting a web page with controls on the MSP430, the outlets can be able to be controlled from anywhere on the same Wi-Fi network. The completed project provides a web page that can both control each of three outlets individually or all three at once. This is done using an MSP430 as a controller with a 434MHz transmitter sending commands to the outlets, and an ESP 8266 Wi-Fi module connecting to the network. A schematic of the completed project is shown in Fig. 1, and a photo of the completed project is shown in Fig. 2. With this set up the outlets can be reliably controlled from anywhere on the same Wi-Fi network. The components required for this project, along with the equipment necessary are listed below. All the components can be purchased for less than $30. I was able to write an interface to control the outlets, as well as serve a webpage to control the outlets. This was the final project for my Embedded Systems class at John Brown University. more details are avalible in the attached file.
