Oil-fired gas boilers refer to boilers that can use both oil and gas. A boiler that can only use oil is called an oil-fired boiler, and a boiler that can only use gas is called a gas-fired boiler.The importance of brazing holding time If the boiler is equipped with an oil-fired gas dual-fuel burner, then the boiler is an oil-fired gas boiler. Oil-fired gas boiler is a relatively general concept. Oil-fired gas boilers are mainly divided into boiling water boilers, hot water boilers, steam boilers and heat transfer oil boilers. When purchasing, choose different oil-fired gas boilers according to their own purposes.Low pressure vacuum carburizing process of Cr17Ni2 stainless steel Oil-fired gas boilers are different from coal-fired boilers in that they require a burner to inject fuel into the boiler hearth, and use a fire chamber to burn without using a grate facility. Vacuum heat treatment furnace for copper alloysSince no fuel ash is produced after the combustion of the oil-fired gas boiler, the oil-fired gas boiler does not need a slag discharge facility. If the oil and gas injected into the furnace are mixed with air within a certain range or extinguished, it is easy to explode. Therefore, oil-fired gas boilers need to use automated combustion and control systems. The oil-fired gas boiler has a compact structure. The small boiler body and its ventilation, water supply, control and auxiliary equipment are all set on a distribution box. The large and medium-sized boilers can also be assembled and shipped.Battery cooler vacuum brazing

Electric steam boiler The hot water or steam generated in the boiler can directly provide the thermal energy required for industrial production and people's life, and can also be converted into mechanical energy through a steam power device, Vacuum heat treatment of aerospace materialsor into electrical energy through a generator. Boilers that provide hot water are called hot water boilers, which are mainly used in life and also have a small amount of applications in industrial production. Boilers that generate steam are called steam boilers, often referred to as boilers, and are mostly used in thermal power plants, ships, locomotives, and industrial and mining enterprises.Vacuum Heat Treatment of Hollow Linear Optical Axis Electric boiler is a kind of electric boiler that uses electricity as energy, converts electric energy into heat energy, heats the heat medium water or organic heat carrier (heat transfer oil) to certain parameters (temperature, pressure) through the heat exchange part of the boiler, and outputs the output with rated power.Martensitic stainless steel quenching vacuum heat treatment process Quality thermal mechanical equipment. Electric boilers can be divided into: KS-D electric water boilers, CLDR (CWDR) electric hot water boilers (including electric heating boilers and electric bathing boilers), LDR (WDR) electric steam boilers, etc. A steam boiler is a boiler that produces steam of specified parameters and quality.

Centrifugal pump is composed of many parts. According to the working state of each part during operation, it can be roughly divided into three categories Type: rotating part, fixed part J4: and handover part. Taking the single-stage single suction horizontal centrifugal pump as an example, as shown in Fig. 2.4, the function, composition, structure and material of each part are introduced. 1 impeller (also known as working wheel) The drum is the main part of the water pump, and even the core part of the water pump. The centrifugal system relies on the high-speed rotation of the impeller Water is used to realize energy conversion. The N1 wheel rubber of the centrifugal pump is composed of two circular cover plates. There is a gap between the cover plates. 1: the bent blade will be two in front and back The two cover plates are connected together, and the space groove surrounded by the two adjacent blades and the front and rear cover plates is generally called the flow of water. (2) accumulated glaze The beam rib is used to rotate the pump impeller. It receives power from the prime mover (motor) and drives the impeller to rotate. Thus, the pump The shaft shall have sufficient torsional strength and rigidity, and its deflection shall not exceed the allowable value; The working speed cannot be close to resonance The critical speed of the phenomenon. Common materials of pump shaft are carbon steel and stainless steel. 3. Key The impeller and the pump rail are connected by keys. The chain is commonly known as the connecting piece of rotating parts. 3 in Fig. 2.4 is a centrifugal pump The usually used flat key can only transmit torque and cannot fix the axial position of the impeller. In large and medium-sized fruits, the leaf The axial position of the wheel is usually located by the shaft sleeve and the nut of the shaft sleeve.

Glass melting furnace features The glass melting furnace is a high-temperature energy-saving vertical resistance furnace specially used for glass melting in the glass industry.Low pressure vacuum carburizing process of Cr17Ni2 stainless steel The main operation process is as follows: put a crucible (the one used in the glass industry) in the furnace, then put the prepared glass frit directly into the crucible from above, and then heat it with electricity, when the temperature rises to more than 1200 ℃, the glass When the frit is in a molten state, use a special crucible hook to open the flow hole at the bottom of the crucible, and the molten glass frit automatically flows into the container below.Vacuum heat treatment of high speed steel It adopts a double-layer shell structure, programmable 50-stage automatic heating, phase-shift triggering, thyristor control, and the furnace is made of alumina polycrystalline fiber material, which has the advantages of balanced temperature field, low surface temperature, fast temperature rise and fall rate, and energy saving. Unique furnace design, durable; Taiwan intelligent automatic temperature controller is a double-line LED display dial, mainly used for GWL-R temperature control, high temperature control accuracy (plus or minus 1 degree), sensitive response, programmable PID control , with deviation, over-temperature alarm and power-off protection, safe and reliable operation.The importance of brazing holding time

The most commonly used home heating is a gas wall-mounted boiler, which heats water through the boiler and pressurizes the water pump to form a hot water cycle to complete the heating process. Precision gear vacuum heat treatmentThere are three main types of gas-fired boilers on the market, casing-type gas-fired boilers, plate-replacement gas-fired boilers, and condensing gas-fired boilers. Although gas-fired boilers still emit exhaust gas, they are still a common heating method for some low-income families.Vacuum Heat Treatment of Hollow Linear Optical Axis Plate exchange boiler The difference from the casing boiler is that when using domestic water, the boiler is specially equipped with a heat exchange plate, which cuts off the heating water circuit through the switching of the electronic three-way valve in the boiler, so that the heated hot water forms a heat exchange in the boiler. Small cycle, through the plate heat exchange to domestic water. Therefore, in terms of constant water temperature, plate-exchange boilers have certain advantages, and their service life is longer than that of jacketed boilers.

Electric heater wood type The heating plate is placed in a wooden box. There are wooden grids on the heating plate and the wooden box are fixed together. An adjustable temperature control switch is installed on the wooden box. One lead wire of the adjustable temperature control switch is connected to the live wire of the power supply. Die steel vacuum quenching processThe other lead wire is connected in series with the fuse and the quick-jump thermostat to the live wire position of the three-eye socket of the heating plate, the neutral position of the three-eye socket is connected to the neutral wire of the power supply, and the ground wire position is connected to the ground wire of the power supply. . There is no external electromagnetic radiation and static electricity when it is heated, and there will be no short-circuit accident when the surface encounters water. At the same time, it can emit far infrared rays to produce health care and physical therapy effects, and it can also achieve uniform and constant temperature heating.Vacuum Brazing Process
