WRN-430M series Wear resistance leakage thermocouple Wear protective paint technology, high chromium…
Description：
Productoverview: WRN-430M seriesWear resistance leakage thermocoupleWear protective paint technology, high chromium cast iron and high temperature alloy made of different materials by plasma tube, specifically for high measurement environment, low temperature resistant design and manufacture, can be used in circulating fluidized bed, fluidized bed furnace, cement rotary kiln tail smoke chamber, pulverized coal furnace, milling machines and other industrial field, using armored or high temperature armored core body, with different materials and specifications of casing wear, abrasion resistance, shock resistance, good thermal shock resistance, several times the products in a variety of harsh occasions wear a high degree of the service life of up to ordinary products high, greatly improving the production efficiency, reduce the cost of consumption. Two, work principle: WRN-430M seriesWear resistance leakage thermocoupleThe electrode is composed of two different conductor materials.The working principle of two different components of the conductor ends by welding, forming a loop direct temperature measuring end call measurement end, terminal end call reference end.When there is temperature difference between the measuring terminal and a reference terminal, will produce thermal emf in the circuit, connected to display instrument, the instrument will indicate the corresponding temperature of the thermocouple electromotive force generated by the value of the.Thermoelectric type WRN thermocouple assembly will increase with the increase of temperature measurement terminal, thermoelectric sizeonly withthermocouple conductor material and the temperature difference between the two ends of the length, diameter and thermal electrode without thermocouple assembly is mainly composed of a junction box, protection tube, insulation casing, terminals, power extremely basic structure, and in a variety of fixed device. Three, application: WRN-430M seriesWear resistance leakage thermocoupleUsing special heat-resistant and wear-resistant alloy material as the outer protection tube and wear measuring head, installed in the Armored Core, not only has high on the fly ash particles erosion corrosion resistance, and the inner core body play a good protective effect under high temperature conditions.The connection form of flange or thread, can measure the temperature of 0~1200 degrees in the long term, is the metallurgical industry using temperature sensor to wear the ideal environment. Four, main features: 1, according to the environmental characteristics of the wear resistant alloy, pure alloy by vacuum melting of specially designed, with special wear-resistant high temperature alloy high temperature oxidation resistance and high strength, the overall drilling and forging.Processing less defects, high reliability, high temperature strength and wear resistance performance is good, the price is higher, with a temperature of 800~1200 DEG C. 2, the composite wear-resistant alloy: the composite armor technology with abrasive particles in the matrix alloy, precision casting.Without turning, the casing of high hardness, high temperature oxidation, some casting defects but does not affect the high temperature wear resistance and sealing, is to use high temperature resistant casing, the most common moderate price, use temperature of 800~1200 DEG C. 3, ion osmosized tungsten carbide: stainless steel substrate by ion beam implantation of tungsten carbide particles in the casing surface infiltration technology.With high hardness, high strength and high toughness, special wear-resistant, wear-resistant layer thickness is 0.5 ~ 1.5mm, hard and tough, the smallest diameter up to 8, good surface quality, use temperature of 0~800 DEG C.In the power plant coal grinding machine used in the life of 2 years. Five, technical parameters: 1, with the same type I thermocouple assembly, thermal resistance, a according to the ordering protocol; 2, non 1Cr18NI9Ti material wear protective tube part; 3, electrical outlet: M20 * 15, NPT1/2; 4, head wear hardness: HRC62-65; 5, protection grade: IP65; 6, every burst: D "BT4, D, CT5; 7, nominal pressure: 2.5MPa. Six, wear protective tube: 1, the measuring range of wear-resistant materials C MPa nominal pressure protection tube mm selection code; 2, 0-800 less than 10 plasma spray paint Phi 16, Phi 18, Phi 25, Phi 38 LM; 3, 0-1150 high chromium cast iron is less than or equal to 15 Phi 25 and phi 38 CM; 4, high temperature alloy 0-1300 is less than or equal to 20 Phi 18 and phi 25, Phi 28 KMA; 5, the surfacing 0-1300 is less than or equal to 20 Phi 18 and phi 25, Phi 28 T. Seven, specifications and models:
Eight,Design selection and ordering: 1, note the type, number, using temperature range index. 2, the thermocouple protection tube diameter, length, material etc.. 3, fasteners, flange, the need to provide relevant dimensions. Customer service service commitment: 1, my company sold ZhongweiThermocouple seriesThe product within twelve months of quality problems, responsible for free maintenance. 2, the warranty period if the products of our company have any quality problems, our company is responsible for free repair or replacement. 3, the warranty period if the user use undeserved, cause damage to the product, our company is responsible for the maintenance, collect the damaged parts cost. 4, after the warranty period of product quality problems, our company is responsible for the maintenance, collect the damaged parts cost. 5, if the user needs to our service, our company in the province of the user service personnel arrived at the scene within 12 hours, 48 hours outside users arrive at the scene.
