Nobeth mobile vehicle after-sales service real-time broadcast:
Stop 60 on the Hubei trip: Hubei Special Cable Group Co., Ltd.
Machine model: CH48kw BH72kw
Number of units: 3
Purchase time: 2016 Service time: 2022.7.19
Usage: With cross-linking room and wire drawing machine, steam curing cable, cable cross-linking
Solution: The customer is making wires and cables. There are two cross-link rooms. One is 4*2*2 meters in length, width and height. Two 48kw and 72kw units are used in parallel. The other one with a length, width and height of 4*1*2 meters uses 48kw and 72kw. The cross-linked room requires a temperature above 95 degrees and a time of 10-12 hours. It is not used much at present and depends on customer demand.
One of the 48kw ones is used to carry a large wire drawing machine, and it only needs to be turned on in one gear. The 18kw one used before is currently idle and in reserve. Customers have reported that the equipment is good and they have visited the company before to see it.
On-site problem: One heating pipe of each 48kw unit was broken, and one of the 48kw safety valves leaked.
Solution:
1) It is recommended that the customer replace the heating pipe and safety valve. Since the on-site equipment is in use, the customer must replace it after the machine is shut down.
2) Remind customers to calibrate the safety valve pressure gauge every year!
3) It is recommended to discharge 0.1-0.2MPA after each use

“You are electricity, you are light, you are the only myth.” One line of lyrics makes the importance of electricity and light clear. Electricity is an indispensable resource in life. Without electricity, I believe everyone’s quality of life will plummet.
Electricity is transmitted to thousands of households through cables. Generally, electric wires are composed of one or several soft wires covered with a light and soft sheath. Cables are composed of one or several insulated-coated wires. During the processing It can be heated with the matching steam cable steam generator, and then wrapped with a tough outer layer made of metal or rubber.
Cables and wires generally consist of three components: core wire, insulating sheath and protective sheath. There is also a heating cable, which uses a single or multiple alloy electric heating wires as the heating source, high-purity, high-temperature, fused crystallized magnesium oxide as the heat-conducting insulator, and seamless continuous stainless steel or copper tubes as the sheath, using special production Made with craftsmanship. In places with strong corrosive effects, PE or low-smoke halogen-free jackets can be added.
In recent years, with the rapid development and scale expansion of China’s electric power, petroleum, chemical industry, urban rail transit, automobile and shipbuilding industries, especially the acceleration of power grid transformation, the construction of ultra-high voltage projects, and the global wire and cable products to China The market size of China’s wire and cable industry has grown rapidly. The wire and cable manufacturing industry has become the largest industry among more than 20 subdivided industries in the electrical and electrical appliance industry, accounting for a quarter.
Even though cables are metal, steam is required to produce them. One of the processes is called cable cross-linking, which means that cables also need to be steamed. There are many ways to steam cables, including digging a cellar, building a steam room, or simply covering it with tarpaulin, but all must be equipped with a steam generator required for steaming cables.
Nowadays, many manufacturers of cables use steam room supporting equipment – steam generators to meet the steam and temperature needs in the process of steaming cables, and there are also many companies that are improving. Originally, heating tubes were used to heat hot water to cook cables, but the effect was not ideal, and it consumed a lot of power and was easily damaged. Later, a steam room was built and an advanced steam generator was used to replace the original and backward cooking method.
Nobeth block steam generator – can deliver steam energy regularly and quantitatively according to the needs of different processes. When different pressures are required, the equipment can adjust the pressure from 0.1 to 1.25MPa according to the needs; high temperature 208°C; thermal efficiency as high as 108%; Intelligent frequency conversion saves time and effort, is low-nitrogen and environmentally friendly, safe and energy-saving, allowing you to use it with peace of mind! Use it with confidence! Comfortable to use!
As we all know, during the cable extrusion process, if the temperature is too high, it will be easily scorched, and if the temperature is too low, it will be difficult to gel. During the vulcanization process, if the temperature is too low, it will easily produce bubbles, and if the temperature is too high, it will easily produce pores. Moreover, each process has different temperature and pressure requirements, so the temperature and pressure control must be accurate and adjustable! Therefore, the cable needs to meet the required steam volume and temperature during the production process. Only such cables will have quality assurance and have a longer service life!
Features
1. Innovation: It uses a flat-plate type fully premixed ceramic burner, which is heated evenly; it adopts reverse combustion technology, so there is no dust accumulation in the body and no need to clean the coke; it is ready to use and produces steam within 5 seconds of starting up; distributed installation, on-demand functions, No special personnel is required and no maintenance is required; the machine does not require pure water, just soft water. Thermal efficiency can be as high as 108%;
2. Safety: It is not a pressure vessel, it has a furnace but no pot, and is exempt from inspection and reporting; the single module has high power, simple structure, and low failure rate. All parts within the heating range of the machine are not welded, effectively avoiding leakage and without any safety hazards.
3. Environmental protection: The heat exchange insulation and pipeline connections are completely made in accordance with the relevant standards of the petrochemical industry, with ultra-low nitrogen oxide emissions and outstanding environmental benefits.
