Comfortable Thermal Manikin Thermal environment test simulation manikin exchange heat from the external environment by simulating the real physiological mechanism. Combining the dummy monitoring results with the software data analysis results to get the different thermal comfort effect through the protective clothing on the manikin. Thermal environment test simulation manikin measures the heat balance relationship between manikin heat production and external environment, analyze the environment effect on the human comfort and the environmental conditions meet the human comfort. It also can characterize the human comfortableness in different environments according to the human comfort results and the heat balance between the dressed dummy that product heat and the external environment. Then it can use to guide the development of comfort fabrics and clothing in the special conditions. Thermal environment test simulation manikin uses the data expression method for human perception conclusions. It avoids the real test without losing the digital and uniform real perception result. As a result, it will reduce the error caused by the differences in personal perception.

VACUUM FURNACE Metallurgical industry: The vacuum technology used in the metallurgical industry includes molten steel vacuum processing, vacuum melting, vacuum induction melting, induction shell melting, vacuum arc remelting, etc. Among them, the vacuum treatment of molten steel is a very important aspect of the metallurgical industry. This technology is mainly used in the atomic energy industry, aerospace technology, ocean drilling technology, gas engine technology, automobile industry, aircraft manufacturing, high-speed trains and other high-tech industries to control and process certain elements in steel, and to The life and reliability of materials put forward higher and higher requirements. The Effect Of Carbon Concentration On Mechanical Properties After Carburizing Heat Treatment Electronics and microelectronics industry: Microelectronics technology requires smaller and smaller electronic components and circuits, and higher integration requirements. This is inseparable from the application of vacuum technology, especially the microfabrication technology of VLSI. The formation of geometrical structure, ultra-thin layer growth technology, and particle beam injection technology all require a high-quality and clean vacuum environment, which shows its development Dependence on vacuum technology and equipment.

VoIP Benefits For The Hospitality Industry Voice over Internet Protocol or VoIP for short, allows for the real-time transmission of voices over the Internet, and has been rising in popularity over the traditional Public Switched Telephone Network (PTSN). VoIP’s versatility and cost-effectiveness make it an attractive solution for an increasing number of industries. As a rule, many hotel customers avoid using hotel room phones due to the prohibitive cost. Many are the customers who have experienced sticker shock when they received their bill and saw how they were being nickel and dimed simply by using the room’s phone a few times. That’s the sort of lesson that sticks with guests, and they make sure that they don’t repeat that mistake again. However, by using a cheaper VoIP system, the hotel can pass those savings on to the guests, making the hotel phones a more attractive option again. Any hotel worth its salt wants to cater not only to vacationing guests, but to professionals on business trips. It’s all part of being all things to all people. VoIP Wi-Fi provides business guests with perks like video conferencing and call bridging, but without the hotel making a huge financial investment. Such an arrangement can turn a modest little hotel into a competitive, world-class facility with minimal monetary outlay. Hotel phone system improves hotel service experience Why is a Hotel Phone System Important IP Phones for Hotel VoIP System

IP PBX phone system is a communication system used in companies. This system manages calls made to the business phone line or to an extension. The IP PBX phone system not only manages calls outside of the organization, but it also makes internal calls easier. Thanks to new technology, virtual PBX systems thrive thanks to VoIP technology, also known as voice over internet protocol. VoIP allows people to communicate using their voice over the internet. The sound going through a call is digitized and allows phone calls to occur in real-time. This IP PBX phone system is a new way to communicate. Just a few years ago, this concept was unimaginable. Most devices could not connect to the internet mobily like they do today. Because of this, it was impossible to consider a virtual phone system. Now, most companies connect to the internet through a computer or cell phone. This allows them to make calls through devices they already own, rather than needing physical phones.

1. The discharge pressure of high-pressure reciprocating pump has nothing to do with structure size and speed. The discharge pressure depends only on the power, strength and sealing function of the pump itself. The flow rate of motor reciprocating pump has nothing to do with the discharge pressure, but when the pressure is high, the flow rate of the pump will change slightly due to the gas dissolved in the liquid and the leakage of valve and packing. Therefore, the reciprocating pump can not adjust the flow by closing the outlet valve. When the discharge valve is closed, the fluctuation of discharge pressure will lead to motor overload or pump damage.

Positive displacement vacuum pump Claw vacuum pump is not only a kind of positive displacement vacuum pump, but also a dry vacuum pump.Claw vacuum pump, like roots vacuum pump and screw vacuum pump, is a non-contact dry vacuum pump. In general, in order to achieve a certain compression ratio, rotational speed and dynamic balance, claw vacuum pump is usually composed of multi-stage claw rotor in series or roots rotor and multi-stage claw rotor in series. At present, three-stage claw rotor and one-stage roots rotor are commonly used, or four-stage claw rotor is connected in series. The performance of roots plus claw type is generally better than that of claw type vacuum pump.In multi-stage claw vacuum pump, according to the form of rotor, phase difference and diaphragm, it can be divided into spiral type, anti claw type and spiral anti claw type, and their performance is also different.For claw type vacuum energy, the higher the rotating speed, the greater the compression ratio. In general, the speed of claw vacuum pump is 3000r / min, and the limit pressure is 1-10pa.Industrial craneRoots BlowersRoots Vacuum Pump

The noise of plunger pump is analyzed and divided into human factors and non-human factors. Taking CY14-1B axial piston pump as an example, the working principle is analyzed first, and then the factors causing noise are found out. Finally, some targeted measures are proposed to reduce noise.Status and classification of hydraulic pumpsMechanical transmission, electrical transmission, hydraulic transmission and pneumatic transmission are commonly used in industry at present. Hydraulic transmission is widely used in all kinds of construction machinery because of its high working pressure, transmission power and the weight of the actuator is relatively large, can be continuously variable and so on. And hydraulic transmission in a very important energy conversion element - hydraulic pump, is widely used.Hydraulic pump, as the power unit in the hydraulic system, plays a vital role in the hydraulic system. According to the type can be divided into blade pump, gear pump, plunger pump, screw pump. Among them, the plunger pump is a common, but also widely used high pressure pump, the noise reduction of the plunger pump this problem, there are many scholars and experts are studying.
