Elevators are devices that are necessary to lower the temperature of the coolant entering residential buildings. This device reduces the temperature of the water by partially mixing with the cold liquid from the return pipe. Currently, water jet elevators are not available at every CHP. Let's take a closer look at what this device is, how it works and whether it makes sense to install it. We will also consider other types of elevators. For example, those used in grain warehouses, etc.

General information

It's no secret that the incoming network coolant must comply with the standards. It is important to take into account hardness, acidity, pressure, and temperature. According to the established standards, the water coming from the mains should not have a temperature higher than 95 degrees Celsius. What causes this, we do not considerWe will, but the fact remains. However, these rules are not always observed. Often, the temperature of the coolant in the network highways reaches more than 130 degrees. To solve this problem, it is necessary to install elevators. This device will help lower the water temperature to normal. Moreover, this is one of the most effective means to control the flow of coolant.

Water jet elevator

Before talking about the principle of operation, it is necessary to deal with the device. Such an elevator consists of a metal housing, in which there is a chamber for mixing the coolant, and a nozzle. The superheated liquid exits directly from the nozzle and immediately enters the mixing chamber. Moreover, the whole process is carried out at extremely high speeds. Because of this, the so-called injection occurs, which is the main reason for the suction of water from the return pipeline. Changing the nozzle diameter allows you to adjust the coolant flow rate, as well as the outlet temperature. We can say that the water jet elevator acts as a circulation pump and a mixer. It is interesting that the device is completely non-volatile and operates on the pressure drop in the network in front of the elevator and in the device. By the way, the available pressure (pressure drop) should have a ratio of 7:1 in relation to the resistance of the heating system.

Do I need such a device?

Actually, this question is quite difficult to answer. Today, not everyone pays attention to compliance with the rules. In addition, the quality of the networkhighways supplying water to residential buildings leave much to be desired. In most cases, it is not superheated water that reaches us, but vice versa. Most likely, this is the fault of the thermal power plant, where temperature regimes are not observed. However, a heating elevator is required to effectively control the heating unit in a building. It will help, if necessary, to lower the temperature of the coolant to normal. In addition, this device does not require regular maintenance and calibration. All that is required is to select the correct nozzle diameter and periodically inspect the unit for visible defects. If it is necessary to change the performance, another, more economical, nozzle is installed. However, selection of the correct pipe and nozzle diameters for the assembly should only be done by design offices.

All about bucket elevators

The device is a vertical conveyor, which is used to move bulk, granular, lumpy and other materials in a strictly vertical position. We can say that among such transporters, this one is considered the most popular. Firstly, its cross-sectional dimensions are small, and secondly, there is ample opportunity to adjust the performance of the device. It is noteworthy that the so-called bucket elevators have a closed body, in which the load is located during lifting. From this it follows that the material is protected from environmental influences and is in complete safety.

The design is extremely simple andincludes a shoe - a loading station, a head - a drive station, and there are also elevator shafts. The material can get into the loading station in several ways (by bucket or by gravity), then it gets into buckets, which move along elevator shafts to the top point, from where unloading takes place. Bucket elevators provide high reliability due to extremely simple design. In addition, the energy consumption of such equipment is at a very low level and is unmatched.

About grain elevators

We can safely say that chain and belt elevators have found wide application in various industries. Today they are used in almost all grain factories. There are such elevators in mills, bakeries, flour mills, etc. Of course, such elevators are designed for heavy-duty use, so the chance that the equipment will fail or fail is minimized. Along with a long service life, it was also possible to achieve uniform transportation of grain and other products, which is extremely important in the grain industry. Usually the grain elevator is equipped with removable panels. This is necessary solely for the quick maintenance of equipment if necessary. In addition, sectional assembly is used, which makes installation fast and extremely accurate.

More about grain elevators

These elevators provide a very good level of productivity. At the same time, the absence of complex and hard-to-maintain units practically eliminateslong downtime of equipment in case of failure of a particular element. In addition, modern bucket elevators are equipped with a brake device, which completely eliminates reverse motion. An explosion breaker is also installed. It will not be superfluous to say that the equipment may differ depending on the project. Sometimes elevators of increased strength and productivity are made, the engine of which can work for quite a long time without rest. If production requires it, elevators are installed that can lift the load to a height of up to 175 meters with a bucket width of 16 to 200 centimeters. If the loads are light, then a special design is used to make transportation even more profitable from an economic point of view. In principle, such elevators are a profitable and expedient solution.

Something else interesting

It often happens that you can't use a belt elevator. If this is an indispensable device for transporting granular materials of small and medium size, then problems may arise with other goods. In this case, it is advisable to use chain elevators that are able to work in more difficult conditions. For example, they are used to move hot goods, both granular and lumpy. In both belt and chain elevators, the bucket volume can vary from 1 to 18 liters. At the same time, the productivity varies in a wide range from 5 to 100 cubic meters per hour. As noted, in the event of an unexpected stop of the device, brakes are installed,which will leave the buckets in the position in which they are now. Of course, the elevator, the price of which is formed depending on the productivity and volume of the bucket, must be purchased only from trusted companies. For example, a bucket elevator with a capacity of 10 t/h will cost 100,000 rubles, but full-fledged grain elevators will cost from 4 to 100 million rubles.

Conclusion

As you can see, elevators are devices necessary for the vertical transportation of goods. But there are also water-jet or heating devices that have nothing to do with chain, belt or bucket elevators. However, you need to understand that vertical transport devices must be manufactured without deviations from the norms and GOSTs, because any malfunction can lead to a heavy load falling and injury or death to workers. At the same time, a water jet elevator is needed to keep your radiators and heating system safe and sound.
