Elevators - devices that are needed to lower the temperature of the coolant entering the residential building.This device reduces the water temperature due to partial mixing of cold fluid from the return line.Currently, water jet elevators are far not at each CHP.Let's take a closer look at that kind of device, how it works and whether it makes sense to install it.Also consider other types of elevators.For example, those used in the grain warehouses, and so on. N.
General
no secret that the coolant entering the network must comply with the standards.It is important to take into account the rigidity, acidity, pressure, and temperature.According to established standards, the water delivered from the backbone should not have a temperature above 95 degrees Celsius.What is the reason, we do not consider, but the fact remains.However, not always complied with those rules.Often the temperature of the coolant in the mains network reaches more than 130 degrees.To solve this problem, you must install the elevators.This device helps to reduce the water temperature to normal.Moreover, it is one of the most effective means of control of the water flow.
Waterjet elevator
Before we talk about the principle of operation, it is necessary to deal with the device.This elevator consists of a metal body, wherein a camera for mixing the coolant and the nozzle.Superheated liquid comes directly from the nozzle and immediately gets into the mixing chamber.Moreover, the entire process is carried out at extremely high speeds.Because of this so-called injection occurs, which is the main cause suction of water from the return pipe.Changing the diameter of the nozzle allows to regulate the water flow and outlet temperature.You can say that the water-jet elevator serves as a circulating pump and mixer.Interestingly, the device is completely non-volatile memory and operates at a pressure drop of the network before the elevator and in the device.Incidentally, the disposable pressure (differential pressure) should have a ratio of 7: 1 with respect to the resistance heating system.
Do I need such a device?
In fact, the answer to this question is quite difficult.Today, not everyone pays attention to compliance.In addition, the quality of the backbone supplying water to residential buildings is poor.In most cases, comes to us not superheated water, and vice versa.Rather, it is the fault CHP, which are not observed temperature regimes.However, for effective control of the heating unit in a building requires heating silo.It will help if necessary to lower the temperature of the coolant to normal.Furthermore, this device does not require regular maintenance and calibration.All that is needed - is to choose the right tip and periodically inspect the unit for any visible defects.If you want to change the performance, set another, more economical, nozzle.However, the selection of the correct diameter pipes and nozzle assembly should be carried out only in design offices.
All that is bucket elevators
device is a vertical conveyor which is used to move bulk, granular, lumpy and other materials in the upright position.You can talk about that among these transporters is considered the most popular.Firstly, its cross-sectional dimensions are small, and secondly, there is ample opportunity to adjust the performance of the instrument.It is noteworthy that the so-called elevator are closed housing, in which the goods are located during the ascent.From this it follows that the matter is protected from the environment and stored in full safety.
The design is extremely simple and includes a shoe - loading station, head - a power station, and there norijnye mine.The loading station can get the material in several ways (bucket or gravity), then it falls into the buckets, which are moved by norijnye to the top of the mines, hence the discharge.Bucket elevators provide high reliability due to the simple design.In addition, power consumption of such equipment are very low and are unmatched.About
cereal noriyah
we can safely say that the chain and belt elevators are widely used in various industries.Today, they are used in virtually all cereal plants.These elevators are on mills, bakeries, flour mills and so on. N. Of course, such elevator designed taking into account the use of heavy-duty, so the chance that the equipment fails or fails, is minimized.In addition to long life and managed to achieve a uniform transportation of grain and other products, which is extremely important in the grain industry.Typically, grain-elevator is equipped with removable panels.It should be an extremely fast service for the equipment, if necessary.In addition, the assembly is used for each section, making installation quick and extremely accurate.
More on grain elevators
Such elevator provide a very good level of performance.The absence of complicated and difficult to maintain node virtually eliminates long downtime in the event of failure of a particular element.In addition, modern elevator equipped with a braking device, which completely eliminates the reverse.Also installed and vzryvorazryaditel.It would not be odd to say that the equipment may vary depending on the project.Sometimes the elevator made of increased strength and performance of the engine which can operate for a long time without a break.If the required production, installed elevator, which can lift a load to a height of 175 meters and a width of buckets from 16 to 200 centimeters.If light loads, it uses a special design that allows you to make transportation more profitable from an economic point of view.In principle, such elevators - it is profitable and expedient solution.
Even something interesting
It often happens that the use of the elevator belt fails.If transport of granular materials of small and average size is an indispensable device, here with other goods can be problems.In this case it is advisable to use the elevator chain, which are able to operate in more severe conditions.For example, they are used to move hot loads, and as granular or lumpy.As in the belt and in the chain bucket elevator volume may vary from 1 to 18 liters.The productivity varies over a wide range from 5 to 100 cubic meters per hour.As noted, in the case of an unforeseen stop device brakes are set, which will leave the buckets in a position in which they are now.Of course, the elevator, the price of which is formed according to the capacity and volume of the bucket must be purchased only in the audited companies.For example, the bucket elevator with capacity of 10 t / h will cost 100 000 rubles, but the full grain elevators would cost from 4 to 100 million rubles.
Conclusion As you can see, elevators - the devices necessary for the vertical transport of goods.But there is a water jet or space heaters that do not have anything to do with the chain, belt, or ladle noriyami.However, it should be understood that the vertical transport devices must be made without departing from the norms and state standards, because any failure could lead to the fall of a heavy load and injury or death of workers.At the same time water-jet elevator is needed to keep your radiators and heating system in the integrity and security.
