SRY9 Sheath-Type Electric Heater with Relay and Temperature Control Structure
It uses multiple 36 stainless steel electric heating elements as a group, and an oil temperature control regulator is installed on the heater. The heater can be divided into one or several groups, and the control can be automatic or manual. The heating core and the electric heating sheath are separable, making maintenance convenient, and the performance is stable and reliable.
SRY9 Sheath-Type Electric Heater with Relay and Temperature Control
The surface power design refers to the JBT2379-93 standard. 0.7w/cm2. The power voltage and overall dimensions can be adjusted according to the factory's requirements. When selecting, the voltage, power, and overall dimensions can be determined based on the standard and needs. Shanghai Guoyi Electric Co., Ltd.'s sheath-type electric heater with relay and temperature control has accumulated high management level, strong technical level, and a relatively complete product system after more than ten years of development, further improving product quality and grade. Our company adheres to the concept of seeking survival by quality, development by technology, opening up the market with integrity, and creating brilliance with hard work, enabling the enterprise to embark on a path of rapid development, thus maximizing the satisfaction of user requirements.
SRY9 Sheath-Type Electric Heater with Relay and Temperature Control Element Instructions
1. The working voltage must not exceed 1.1 times its rated value, and the shell should be effectively grounded.
2. The dimension "B" in the figure must be fully immersed in oil (and checked regularly) to avoid burning. The heated oil should be free of corrosive gases.
3. The installation hole size of this electric heater is φ65mm.
4. The tubular electric heating element is designed according to the JB2379-78 flowing oil standard, with a surface load of 2-3.8 w/cm2.
5. When selecting, the heater size should be determined based on the actual size of the heating medium.
SRY9 Sheath-Type Heater
An electric heater refers to an electrical appliance that uses electrical energy to achieve heating effects. It is small in size, high in heating power, widely used, adopts intelligent control mode, has high temperature control accuracy, and can be networked with computers. It has a wide range of applications, long life, and high reliability. The core of the heater principle is energy conversion, and the most widespread is the conversion of electrical energy into thermal energy.
Heaters are commonly used electric heating devices. People are increasingly inseparable from them.
For example, an electric heater uses metal to generate eddy currents in an alternating magnetic field to heat itself, converting electrical energy into light energy; for example, a solar water heater absorbs solar radiation heat energy and solar light energy (photoelectric effect) and converts them into thermal energy, or both; bioenergy is a form of energy stored as chemical energy using organisms as carriers, directly or indirectly derived from plant photosynthesis. In addition, there are nuclear energy and wind energy conversion modes, but they generally need to be converted into electrical energy for use.
1. After the heater has been running for a period of time (depending on user usage), the ignition plug should be unscrewed to clean carbon deposits. If the ignition plug wire is burned out, it should be removed and replaced with a new ignition plug.
2. If carbon deposits are too heavy, causing reduced thermal efficiency, clean the heat sink on the inner wall of the water jacket and the carbon deposits in the combustion chamber.
3. If the heater's air intake pipe, exhaust pipe, and oil drip pipe are blocked by mud, clean and unblock them promptly. Keep the heater compartment clean, and no flammable debris should be placed around it.
4. Ensure the fuel tank, oil pipe, and fuel filter solenoid valve are clean to prevent dirt from blocking the oil circuit.
5. In the heater circulation system, use antifreeze suitable for the ambient temperature as the circulating heating medium.
6. The heater water pump should be checked regularly according to user usage. If the water seal component leaks or the pump starts with difficulty, repair it promptly.
7. The automatic control box, fuel filter solenoid valve, and other electrical components on the heater main unit should be maintained according to general low-voltage electrical maintenance methods. The performance parameters of the automatic control box have been carefully debugged by the manufacturer before leaving the factory, and users should not modify them arbitrarily.
8. Ensure the thermal control components are in good condition, check regularly, and if the micro switch is found to be malfunctioning or damaged, replace it promptly.
9. The main motor used in the heater normally does not require maintenance for 5000 hours of use. If it works abnormally due to prolonged use or other reasons, it should be inspected, checking carbon brush wear or bearing lubrication, and if necessary, add lubricating grease or replace carbon brushes.
10. During the warm season when the heater is not in use, start it 4-5 times regularly, each time running for about 5 minutes, to ensure normal operation the next time it is used.
