The use of industrial machinery in the field of electric heating rods
Electric heating rods relative to other heating elements with heating speed, small size, high wattage load, the characteristics of high heat, mold and machinery equipment more suitable, especially for some of the heated space limitations mold suitable for mechanical devices with easy to install and rapid heating characteristics.
Electric heating rods applicable areas:
In addition to heating rods in the mold industry is extensive use of land, but in the fast-sealing machine, shoe, hat machinery, tobacco machinery, thermoforming equipment, casting pipes, pipe machinery, pharmaceutical equipment, plastic mold and other fields also have a wide range of applications.
The electrical heating rod design parameters:
1 Diameter: 6-25MM.
2 Material: stainless steel or Incoloy
3 Design voltage: 24-440V.
4 Power load: 1W/cm² ~ 17W/cm².
5 Tube length: 30MM-2500MM.
6 Installation: thread type, flange type, baffle limit spacing type etc.
7 Outlet: high-temperature wire, terminals, lugs, etc.
8 Internal heating methods: segmented type, soaking type and so on.
(Electric heating rods can be customized according to customer’s needs, make a reasonable proposal within the design area)
The rational design of electric heating element significance:
Single-head electric heating tube interior design should be reasonable and effective, using high-purity magnesium oxide powder as filler material. Have a high thermal conductivity, using non-core grinding equipment, internal distribution and reasonable heat evenly, fast heating, cooling fast, stable quality, long life, with a reasonable design and advanced technology to produce a single head heating tube, stable quality, the use of safe. According to the specific use environment make reasonable scientific design, heating pipe work stability, long service life.
What should we pay attention to when using the electric heating element?
The terminal of the electric heating tube should be relatively fastened with two nuts when wiring. Do not use too much force to avoid the loosening of the lead screw and damage the electric heating tube.
The heating tube should be stored in a dry warehouse. If the surface is damp due to long-term storage, use a megohmmeter to measure the insulation resistance. If it is less than 1 megohm/500 volts, the electric heating tube should be placed in a 200 degree drying oven for drying.
The heating part of the electric heating tube should be completely immersed in the heating medium to avoid damage to the electric heating tube due to undesirable heat dissipation and exceeding the allowable heating temperature. In addition, the lead-out part of the wiring should be exposed to the insulation layer of the heater or outside the heater, so that this part should not be overheated and damaged.
Input power, the voltage should not exceed 10% of the rated voltage marked on the various electric heating tubes. If it is suitable for lower than the rated voltage, the heat generated by the electric heating tube will also decrease.
The terminal of the electric heating tube should be kept clean and dry. Otherwise, it will reduce the insulation performance and be short-circuited. The insulating and sealing device is strictly protected to prevent accidents.
When heating certain viscose and other substances, such as sodium nitrate, stearic acid, paraffin, etc., the power supply voltage should be lowered at the beginning of heating to reduce the heat generation of the industrial electric heating tube. To the rated voltage for heating.
The electric heating tube has been used for a long time. If thick tube dirt and grease accumulate on the surface, it should be removed regularly, otherwise it will reduce the heat transfer performance of the electric heating tube and cause the heat load on the surface of the tube to exceed the rated allowable and be damaged.
The special electric heating tube should be carefully read the relevant instructions before installation and use, so as not to damage it.
Special attention should be paid to the heating medium when selecting electric heating tubes. It should have no corrosive effect on the material of the electric heating tube and shell.
Why deep fryer heating element suddenly heats up very slowly？
Method 1
Not power saving.
Method 2
Electric deep fryer slow heating can be equipped with an adjustable booster, speed with you.
First what you need to know whether it is the cause of the " electric deep fryer" or the cause of the line or electricity meter, take the machine to its work to promote the shortage of life support miles his home to try, if still slow temperature, see if the temperature is not set ( or gear is not adjusted ).
Electric deep fryer can fry all kinds of meat, vegetable twist, fruit and other food with ordinary household electricity. Electric deep fryer on the market is generally a machine multi - purpose, not only can fry food, also can be used to cook. Electric frying pan is designed to absorb the advantages of similar products at home and abroad, with novel style, reasonable structure, convenient operation, fast heating speed and other characteristics, is a special equipment for fast food restaurants. It is also the ideal food processing equipment to be sold now. Electric deep fryer is a necessary kitchen utensil in modern people's life.
