Heating rods are one of the most commonly used equipment for fish farmers. Over time, the wires are aged and the contacts are oxidized and may fail. In the course of using there must be many problems and precautions need to understand, the use of heating rods may not be very understanding of many people, the following small series briefly introduces the use of heating rods . 1, the life of the heating rod: heating rods generally need to be replaced within a maximum of two years, because of its internal bimetal to work. If you do not change it, it's easy to happen to "boil fish." 2. Is the glass good or stainless steel? This is hard to say. Each has its own advantages. For example, glass can be used in a seawater tank. Metal can't. Metal heating rods can be used in large fish tanks. Glass heating rods, if used in large fish tanks, must be damaged by fish. 3, domestic heating rods can be, there is no need to buy imported. The quality of heating rods can be distinguished from many places, not necessarily expensive. Some of the expensive glass is not the same, and the heating wire is different. This large part affects the price of the heating rod. However, if he does not jump bimetal, he will cook the fish soup faster. Just like stainless steel, many of them use electronic temperature control. A thermistor detects the temperature of the water. After switching, it controls the relay or high-power thyristor to control the on/off of the heating tube. This accuracy is higher than the average bimetal, but if the thermistor or SCR problems, he will heat faster than the average glass. 4, heating rod maintenance. If it is glass, the glass is generally broken, so that only one shell is replaced. Generally there is a special glass tube on the market. When changing, be careful not to move the adjustable screw on the bimetal. Otherwise heating will not be allowed. Also note that the seal should not leak when installed. Stainless steel generally has no repair value, and it is better to change one. If it is outside the temperature can find a general appliance repair shop, let them help to see, most of the SCR burning. 5, is generally the first calculation of the tank's water capacity, one liter of water relative to 1,5W --- 2W heating rod is best, for example, my tank water capacity is 100 liters, you can use 150W to 200W. If a large tank, such as a 300-400-liter tank, should use a 500-watt tank, but try to buy two 300-watt tanks. This has the advantage that the heating is faster and the tank can be placed on one side. Even if there is a problem, it is not enough to raise the temperature of the water quickly. 6, when the use of the heating rod if the shell is broken, we do not panic, generally do not electrocuted the fish, as long as the power is broken out for a change on the line. Normal use is generally not bad, and it is caused when everyone changes the water or cleans the water surface. Be careful to take out the power after a while, otherwise there will be burns. Information on the use of heating rods has been introduced here for everyone. I hope this article will help you.
