Steel tanks used for transportation and storage of aggressive chemicals such as hydrofluoric acid (60% HF). Concentrated sulfuric acid or sodium hydroxide solution may be stored in steel capacity. For primary treatment of oil used by the buffer capacity, raw capacity, underground tanks and storage tanks for petroleum products, as well as containers for mixing of reagents. During the construction of gas stations used underground storage tanks for fuel. Capacity for the gas station, usually equipped with technological cap, pipe line filling, piping fence line of fuel with the inlet valve and line removal of water. In the construction of steel tanks used to store loose, viscous materials, paints, and also for preparation of concrete. The following describes an example of capacity during storage of milk. Capacity for storage of milk.
Equipment. Storage capacity. Transport tank with milk (cream), arriving at the dairy plant, are discharged into special storage tanks. In these tanks the milk (cream) and accumulates kept the whole period (about a day without significant changes in quality) prior to processing. Storage tanks come in various sizes.
Typically, tanks are manufactured with up to 100 000 – 120 000 hp or more. GoPro Hero 9 brings even more insight to the discussion. In the west, sometimes use capacity of up to 250,000 liters. Storage capacity of milk is produced from stainless steel and aluminum. Occasionally, tanks made of mild steel and polymeric materials. Tanks are equipped with hermetically sealed hatches. To maintain a constant temperature, provides insulation capacity (usually cork) and wood paneling. To prevent the settling of milk during storage, installed propeller stirrer speed is 100 – 250 rpm with, or screw type. In the tanks of large capacity (70 000 liters and more) product is generally mixed with air. Milk storage tanks can be equipped with a refrigerator, placed inside or outside the tank. Outside, on the basis of health and sanitation requirements, are preferred. For external cooling capacity, using plate coolers, they are placed on the container body or separately. In this case, increases the intensity of heat transfer and facilitates the application of ammonia cooling system. Filling a container with the milk flow from the inlet pipe is fed to the vessel wall, to the extent possible to reduce foaming. The level of milk in the tank is determined by the viewing window or molokomernomu glass. Overflow tank warning device (float type). Current is applied to the container body or on a tube inserted in the middle of the tank, as well as to the contacts established at the top of the tank. When filling the tank float rises. If the tank is filled with product, then float, referring to the top contact closes the circuit, resulting in fires light or sound. Storage tanks installed on a stand with a socket on a groove that allows you to change their slope. Milk storage tanks are also equipped with instruments to monitor the quality of the product (eg, instrument for measuring the pH level). In addition, the device provides for the automatic preset include mixers, mixing milk, maintaining the desired product temperature, filling and emptying of individual tanks with an appropriate alarm (light or sound), and in some cases to account for the filling capacity of milk. Large capacity capacity compared with other offer several advantages. Milk is stored in them for a long time without significant changes in temperature, both in winter and in summer, even if they are not installed inside and outside premises. When storing milk containers simplifies maintenance and reduces the initial costs of their production (per unit of output).
Also, the power supply should be protecting the battery from deep discharge and maintain short-circuit power output of 12 V. The fourth option – it is desirable that the system had Remote led display, which allows you to visually monitor the status of the device. It is very important when using electronic switches such as Touch Memory, key fobs and cards for remote arm and disarm the device with protection. The fifth option: it is necessary for the system to a single message more fully describe the state of the system of protection, For example, an alarm indicating the zone in the state of GSM-system, describe how the relay protection included how much charge is left in the battery, what is the telephone line (if any). There are additional optional parameters – For example, depending on their level of GSM-protection can not only inform the owner about the problems of protection, but also independently to respond to such stimuli. Since attackers can, and block the cellular network in District with a simple cellular "jammers", it is important that, in response, say, the invasion, the system is not just going over numbers to send sms messages as "happy" news, and immediately use alternative methods delivery of the message or include sirens, opened the cells with the dogs, bodyguards, the light on, or allowed tear gas. The sixth option – it is very important to know how to burglar alarms to monitor the availability or no signal from the base station.
Virtually all models GSM-signaling devices used by an attacker or suppress signal interference is a problem, but solvable. The system simply must be able to to signal an alarm prior to the owner of the building or premises with a deterioration of signal quality from base station. And in the absence of the main channel – use alternative. So, to summarize. Principle gsm security alarm system works is as follows: the device has multiple inputs for sensors and multiple outputs for the actuators, as well as cellular gsm module. When firing one or several sensors (motion, smoke, volume, noise, and others) are connected to the input device, alarm system gsm security immediately dials or sends SMS-messages to preset numbers.
Simultaneously, the trigger appropriate actuators. For example, in the event of a fire extinguishing system activated. Manage the work of GSM-alarm system remotely via a telephone call or an SMS-message. Main differences and advantages of the GSM-alarm systems: * Completely wireless gsm alarm system: does not require wiring, walls of other construction-related violation of the interior. * Very easy to install and service: installation and configuration of gsm signal from a layman takes 15-30 minutes. * Independently deters intruders inclusion of a powerful siren and simultaneously begins to auto dialing, sending sms and voice messages specified phone number. * Has built-in capacity battery, allowing gsm alarm systems work without electrical connections to 5 days. * Works and sub-zero temperatures, so the complex can be operated in winter in unheated spaces, such as: garage, summerhouse, storage and others. * The control panel has a built-in microphone allows you to remotely listen to the room with the phone. * Cheaper existing Today analogues. * Has a single control panel with built-in receiver-transmitter, GSM-modem and programmer.
Chemical pump used for pumping all kinds of corrosive liquids by pipeline. Feature of these pumps, which distinguishes them from ordinary, is precisely the presence of aggressive environments. Depending on the aggressiveness of the environment, density, abrasion, temperature and other properties, chemical pumps, various materials flowing part, including a chemically resistant version polymers. In addition, from the working environment depends pump design. It is worth noting that in the manufacture of components for the chemical pump is not used cast iron, because it is absolutely resistant to the action of aggressive media.
In addition to these shortcomings, cast iron has one – he is a rather brittle material, and therefore can not be used for installation in pipelines with high pressure working environment. Classification of chemical pumps are produced primarily for their design. Distinguish such species: horizontal pumps – are driven by a motor with direct drive and are used for fast pumping of the liquid. Vertical pumps – they are used for rapid pumping of liquid and installed on the tank, and they plunged into the work environment. Such pumps have a great performance. drum pumps – used in cases where it is necessary to pump corrosive liquids from drums, containers, tubs and other containers.
peristaltic pumps – how they work based on the fact that the rollers inside the pump flexible tube or rubber hose with a liquid, while pushing the fluid forward motion. The main applications of chemical pumps are chemical, paint, food and petrochemical industries. Chemical pump in Tyumen and other cities is of particular importance, because many in the Ural region refineries and chemical plants. Chemical pump is indispensable in the pipeline with an aggressive environment – acid and alkali, organic fertilizers, liquefied gases and other fluids, which are those that are explosive and toxic.

Edge banding machines are the basis for furniture production. On the quality of performance edge banding machine depends and quality of furniture produced by you, the price, class furniture. If you are not convinced, visit Pete Cashmore. divided into prime position with manual submission of blanks, one-sided edge banding machines and bilateral edge banding line. Distinct and equipment options for each type of machine – edge banding equipment equipment depends on the complexity of items of furniture, the volume of production, customer requirements for quality wrapping and other nuances to take into account the company's engineers Prime Technologies – the selection of edge banding machine at the customer's problem. Briefly tell you about each type of edge banding equipment. Edge banding machine with manual feeding blank – otherwise it is called positional kromochnik. According to Don Slager, who has experience with these questions.
Used when need wrapping curved edge workpieces, such as tables (most often the edge nonrectilinear configuration found in the office and computer desks), cabinets, closets, etc. Also, this type work on small and medium-sized, in terms of output, the enterprises where the use of edge banding machine transmission type itself does not pay. Edge Banders transmission type can be divided into two categories: One-sided edge banding machines – used in medium and large enterprises. At large factories used several unilateral edge banding machines, united among themselves, driving roller table, including pivoting. Also, some manufacturers are made edge banding machines, as a left-hand performance of the location of the conveyor chain, and right – in this case, for wrapping blanks on all four sides are successively set in a line two odnostronnih edge banding machine with the left and right arrangement of conveyor chains as well as swivel and return roller tables. Machines of this type allow oblitsevat only straight panel details, but they present a number of additional units (not available on the positional kromochnikah) to increase the quality veneered finish details – such as the removal of the longitudinal and transverse overhangs, the cycle to remove excess glue, polished edges, hair dryers for the return of pristine pvc edge colors, broken in the process of machining and other bilateral edge banding machines – here chamfering blanks is performed simultaneously on both sides.
This article focuses on the story about the main types of metal. Although we usually do not know about that sort of thing, and are unlikely to recognize that the most metal-roll in the final product, but a variety of rolled products are a very significant role in our lives. Convince yourself – zelo this indispensable product, and benefit from it a lot. Metal-roll, as a phenomenon has arisen in parallel with the advent of powerful steam engines, which made it possible fast processing of large amounts of metal. This happened in the xviii century, and in the first half of the xix century appeared the first technology that allowed soon to produce large pipes, gun barrels, steel plates, etc. Active development of industry led to the rapid economic growth in Europe and the U.S., because metal products to show their best side. Since then rolled finds applications in various fields – in engineering, construction, laying communications, insulation and cladding, and even sculpture. This is because the steel structure is and remains one of the most affordable and durable materials in the world, and metal products is the most suitable type of most designs for a variety of works.
Neither branch of the economy today is not without metal products. Of course, somewhere used high-tech alloys, somewhere may be applied and more primitive metal. Nevertheless, here take at least a conventional pipe – where they do not apply! This long-distance pipelines and oil pipelines. This communication network the big cities – water, sewerage, central heating, the shell for various kinds of cables, both electric and telephone, optical, television, and many others.
The invention of the pump dates back to antiquity. The first pump for fighting fires, a mechanic who invented the ancient Ktesiby was described in 1. bc. er. Ancient Greek scientists Heron of Alexandria in his work Pneumatica, and then M. Vitruvius in his work De Architectura.
Simple wooden pumps with a through piston for lifting water from wells, probably used even earlier. Prior to the 18 century. Piston pumps, compared with water-lifting machines were rarely used. In the future due to rising water demand and the need to increase the height of its filing, especially after the steam machines, pumps have gradually displace the water-lifting machine. Requirements to them and their conditions applications become more diverse, so along with piston pumps are rotary pumps to create, as well as various devices for pressurized fluid. Thus, historically, there have been three direction for their future development: establishment of piston pumps, rotational, hydraulic devices with no moving working parts. The rise in the development of reciprocating pumps observed in the late 18 century.
When to make them began to apply the metal and use the drive from the steam engine. Since the mid 19 century. have been widely implemented in the production of steam Self-acting piston pumps. This period is the creation of vane pumps, the prototype of which is the piston with an annular cylinder, described the French engineer A. Ramello in 1588 (Le diverse et articiose machine). Development of the theory of piston pumps is closely linked with the work of local scientists and engineers (C.
