Radiant heating – the most efficient way to heat large areas (warehouses, hangars, industrial halls, sports facilities, exhibition halls). The idea of heating radiation otnnyud not new. However, long time, infrared radiation primarily used in agriculture. Modern automation tools, will significantly increase the scope of infrared emitters. On the territory of Russia allowed the use of radiant heating for the Class F5.1, F5.2 for functional fire opanosti except for the Class A, B on explosive. Radiant heating systems have been widely use in Europe and the U.S., but in the last decade in Russia. To date, it can be argued that this is not new, but proven technology. The main advantages of heating by radiation: 1) Cost.
Less air temperature in a heated room – saving on consumption of natural gas. The cost of installation and the hardware itself is also lower compared to conventional boilers 2) The best hygiene and temperature conditions of the premises. Radiation is absorbed by walls and floor, the floor and walls are always warm, the moisture on the inside walls in the working zone is formed, increases comfort, the largest The room temperature is set in the working area, not the ceiling. 3) No coolant in the system. 4) The cost of servicing the heating system is 2-5 times lower than conventional heating systems. 5) By compared with the boilers do not require a device separate rooms – do not spend an internal volume and a useful area of the building. We will be happy to answer your questions
Industrial vacuum cleaners, unlike their smaller counterparts, used in the home to collect dust or dirt, is also able to remove sawdust, metal shavings, cement and other construction debris. Therefore, industrial vacuum cleaners used as a rule, cleaning of industrial premises, with construction and repair works in the food industry. In general, used for complex and large-scale harvesting. Industrial vacuum cleaners are of the following Types: Industrial vacuum cleaners for dry cleaning (can be fitted with single phase or three phase motor). Some models are used as stationary systems, including for air transportation. Industrial vacuums for wet and dry cleaning (fitted, depending on the model, a powerful single-phase or three phase motor with long service). Safe cleaners (designed to work in hazardous conditions).
May work in hazardous environments, used to collect harmful to human health of dust, etc. Central cleaning system. This stationary systems, which provide an economical solution to large rooms. At that should look for when choosing an industrial vacuum cleaner: 1. Type of filter.
Industrial vacuum cleaners with water filter have greater suction capacity and a higher degree of purification of air in the exhaust, more length of service, lets you clean dirt and liquids, but their main drawback is that these vacuums are significantly more expensive vacuum cleaners with filter bags. Most the same quality is mechanical vortex filter: it significantly saves conventional filters and performs high-end air purification. 2. Type of pollutant. Emit pollutants of concern, such as water, polymer powder paint, washing powders and solutions, gypsum, cement and standard: sawdust, debris, sand, pea gravel, abrasive dust. 3. Performance, duration of continuous work in difficult and heavy conditions. Better to give preference vacuum cleaner with Dual turbines. These cleaners can have non-stop operation, in contrast to single circuit. Professor Rita McGrath wanted to know more. Longer than half an hour in an industrial environment single-circuit vacuum cleaners can not work. Pay attention also on the power consumption of an industrial vacuum cleaner: 220-380 volts. 4. The cost of parts and service life. When choosing a vacuum cleaner should pay attention to the availability of supplies, to specify what supplies need to buy additional materials to the vacuum cleaner. 5. Type of housing. Industrial vacuum cleaners with dust-filled bunker has a larger mass. Therefore desirable durable metal casing, compound gears with the body must withstand significant loads.
These devices continuously monitor changes in air temperature and regulate the flow of coolant in the radiator. Incidentally, these relatively new for us, the device is very useful. Indeed, although monitor the temperature can be independently, periodically asking the boiler heating the new settings, it is unlikely anyone will do it in practice all the time. Greenberg Traurig often expresses his thoughts on the topic. Therefore, for these purposes has long been used radiator thermostats, the first prototypes are already half a century ago were designed Danish company Danfoss, which today is a leader in this field. They make it possible to maintain the air temperature in the range from +6 to +26 C, the desired level, with an accuracy of 1 C. To obtain the expected effect of the thermostat, it should be properly set: do not hide behind curtains, with decorative lattice, in niches, etc. If, for whatever reason, to ensure these conditions are difficult, you can use a thermostatic element with a remote sensor, which can be attributed to the valve on the 2,5 or 8 meters. In this case, the thermostat will stabilize the temperature in the location of the sensor.
Another possibility to create a "separate" heating for each room is to use the channel of air conditioners. It is they who are best suited for private homes. In this case, there is only one external unit; indoor unit is installed in the apartment secretly. On the walls or ceiling are intake (sucking the air out of rooms) of the lattice and air distribution diffusers through which the premises come Air conditioning.
To examine the structure of the rollers used in roller table complete, we give them (the movies) a brief description and complete a description of links to pages where you can see and study drawings. Conveyor rollers consist of three main parts. The first – a body that bears the structural features in addition to all function of the surface on which the cargo is moved. The second part – a spindle. The spindle is located in the video lengthwise, center, and has dimensions slightly larger in length than the body roll. In other words, the spindle a little longer, which is due, because with the help of roller guides attached to the roller table.
These projections are called tips of the spindle. Between the spindle and bearing housing is located, connects them and allows you to rotate the roller. Movie has a few basic dimensions: the inner and outer diameters of the casing, the length of the working roller surface, the length of the video and installation length (the length of the tip of the spindle). Each of these parameters are calculated separately taking into account the loads and conditions of use. In the order in which we listed three the main components of video, we will consider them in detail. Hull rollers are made of various metals, but more often for these purposes as a basis applicable steel, aluminum or stainless steel.
There hull rollers are made of plastic. Of course each of these materials is designed for a certain capacity, resistance to wear and abrasion, and therefore selected in accordance with the conditions in which he would have work. Additionally, rollers for roller tables are covered with zinc, rubber, polyvinyl chloride (PVC), as well as customer-specific and anti-static performance of the surface. Spindles made of steel or stainless steel. For them, it is possible zinc coating, but due to the fact that such a coating is applied very rarely, it can be done by zaprosu.Varianty extremities of the spindles are completely dependent on their type, size themselves extremities and mode of attachment to the guide roller table. Brief mention may be some of the extremities: M – male and nut; agm – with male thread; igm – with internal thread; Glatt – smooth; sw – for the groove; fa – spring-loaded. To characterize the bearings that are mounted on rollers for roller tables, enough of one phrase: roller equipped with different types of radial ball bearings. We already know that the rollers for roller table There are motorized and non-drive for them, there are certain accessories. Further to our conversation will continue on as different from each other, these types of rollers, which are installed on their accessories and what functions they carry. We also consider the tapered rollers, why should they apply, and opened a more detailed speech about themselves roller table.
