Description:

Productoverview:

WRN-430MQ series Wear off thermocouple Wear 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, using armored or armored core body temperature, 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 service life of common products is high, greatly improving the production efficiency, reduce the cost of consumption.

Two, work principle:

WRN-430MQ series wear off thermocouple electrodes by 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-430MQ series wear off thermocouple in head wear surfacing the hardness of the steel increased. Applicable to the production site of high wear-resistant solid particles or fluid, when the protective tube is damaged can be cut off by thermocouple. The temperature measuring device is FCC indispensable.

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.

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, the most common is the use of high temperature wear casing, moderate price.

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.

Five, technical parameters:

1, electrical outlet: M20 * 15, NPT1/2;

2, head wear hardness: HRC62-65;

3, protection grade: IP65;

Burst 4, isolation: D / / BT4, D / / CT5;

5, nominal pressure: 2.5MPa.

Sixth, wear protection tube that:

1, wear-resistant materials: measuring range C MPa nominal pressure protection tube mm selection code;

2, plasma spray paint: 0-800 = 10 Phi 16 and phi 18 and phi 25, Phi 38 LM;

3, high chromium cast iron: 0-1150 = 15 Phi 25, Phi 38 CM;

4, high temperature alloy: 0-1300 = 20 Phi 18, Phi 25, Phi 28 KMA;

5, surfacing: 0-1300 = 20 Phi 18, Phi 25, Phi 28 T.

Seven, installation method:

1, first of all should be measured or the screw thread of the thermocouple flange size, supporting flange or thread processing base.

2, according to the size of the base flange or threaded hole in the pipe, the need to measure.

3, the flange or the screw tooth of the welding. The flange or thread is inserted has opened hole in the flange or threaded seat base and pipeline measured welding.

4, the thermocouple with bolts or screw threaded into the base has good welding.

5, according to the wiring diagram to the thermocouple junction box connection, and display instrument is connected on the dial corresponding. Connection box can not contact with the wall of the measured medium pipeline, ensure the junction box temperature not exceeding 100 DEG C. Outlet hole junction box should prevent due to poor sealing, water vapor dust deposition caused by short circuit terminal.
