Recently, KSB Group introduced a new series of pumps, several new pump design improvements to further improve the stability of its series. For example, the pump cover has four stiffeners that make it more robust when heated. Finite element calculations show that the newly designed pump cover is thirteen times more robust. The EthanormSYT's VenJet Exhaust System (patent pending) makes the hot fluid transport safer. For many HTM production processes, the "right" temperature determines the quality and energy balance of the final product. Heat transfer system piping in the modern production enterprises play an important role. Pump Type EtanormSYT Its VenJet exhaust system (patent pending) makes hot fluid transport safer. EtanormSYT Heat exchange mediums manufactured by KSB are commonly used in various chemical industries and are used for heating pipes; for drying lumber when making floor boards; for cooking edible oil before frying hamburgers; without them, tar can not be transport. Slab 180 ℃ temperature, operators tend to choose HTF, rather than water or steam. In order to reduce costs, heat transfer performance of mineral oil is still widely used, but the importance of synthetic heat transfer oil is increasing. Synthetic oils have a much better thermal conductivity than mineral oils and they have a slow coking rate and thus have a longer useful life at higher media temperatures. However, one of the advantages of being an operator has created significant challenges for pump engineers. The synthetic heat-conducting oil has the disadvantages of low viscosity and poor lubricating property, and spreads more easily than the mineral oil. And most importantly, they are highly aggressive chemicals. VenJet, Exhaust Systems KSB has patented an increase of safety in applications involving heat transport. More troubling to the pump engineering community, HTF tends to split into more and more low-boiling and high-boiling forms as coking continues at high temperatures. Due to the high boiling point morphology settling at some point in the system, the low boiling point form is easily vaporized and the gas at operating temperature can enter the bearing support, keeping the sliding bearings and mechanical seals in hazardous conditions. The new system often contains a small amount of residual rinse water, which evaporates when the system is first operated and further increases the amount of gas in the pump. The EtanormSYT is equipped with an exhaust system to ensure that low-boiling vaporization gas or steam does not come in contact with the plain bearings or mechanical seals. The new series of pumps is a long-tested, highly reliable version of EtanormSYA. Several new pump design improvements to further improve the stability of its series. For example, the pump cover has four stiffeners that make it more robust when heated. Finite element calculations show that the newly designed pump cover is thirteen times more robust. The new rib design greatly reduces the risk of deformation during pump operation. System-induced small deviations and applied pressure, on the whole, have little effect on the bearing and shaft seal pump. The new rib design allows design engineers to optimize the "neck" of the pump cover. As a result of the optimized design, less heat will be introduced into the bearing bracket, allowing the bearing bracket temperature to work well well below the critical temperature range. The new SYT series can also be used with flushing system series arrangement of double-end mechanical seal scheme (Figure 3). In this design, the bearing bracket has an intermediate partition that creates a separate cooling space for the mechanical seal chamber. The mechanical seal used is a standard (short-term available) designed mechanical seal. This sealed version safely handles media with vapor pressures in excess of 1 bar at critical operating temperatures. Pumps are available with ceramic bearings for high solids solids. Important connections between the pump body and the pump cover, as well as between the pump cover and the bearing housing, use gaskets. This makes the pump run reliably because the washer avoids wear. Lubrication of ball bearings filled with special grease as part of the overall design concept also enhances the overall pump stability. New Series SYT Double End Series Cartridge with Flushing System Due to the new vent chamber (patent pending), the gas generated during pump operation collects in a separate space. There can also be safely dealt with. The mechanical seal cavity is completely filled with liquid in order to prevent economic overheating and damage to the shaft seal. VenJet separates part of the fluid from the mechanical seal chamber, separates the gas, and returns this part of the fluid to this chamber. This means that instead of reducing the flow of the mechanical seal chamber itself, this part of the return fluid is accelerated in the exhaust chamber, creating a degassing circuit. Since this process is continuous while the pump is running, there is no accumulation of gas around the mechanical seal. The separated gas collects in the VenJet exhaust chamber until it is discharged. The new pump series new pump series tested in Knutsport, Switzerland has gone through the field test. Among them are the Swiss particleboard maker Knobbon. The company has been using KSB's heat transfer pumps at its Menznau manufacturing facility since 1969. Kronos is currently using 80 heat transfer pumps in its production unit in Frankenthal. Customer agrees to test and test the new EtanormSYT heat transfer oil pump as the new series of pumps can use synthetic heat medium. Heat pump unit operates on a 24/7 basis for transporting 285 ° C HTF. For this purpose, biomass-regenerated wood, waste wood and bark are used as fuel. In order to keep running, it takes 10 tons of wood per hour. The pilot pump EtanormSYT150-400 has a flow rate of 470 m / h with a head of 46 m and an efficiency of 83.8%. So far, field test pumps have worked well, especially pumping synthetic HTF. Operators benefit greatly from the new exhaust technology, which prevents system failures caused by gas emissions. All heat transfer circuits work on the same principle: the heat medium pumped by the centrifugal pump flows along the wall of the heat exchanger and the heat enters the system through the wall. According to the operating conditions, there is a difference between the various systems: ①In pressureless systems, the fluid is usually water. This choice is the simplest solution for the plant's engineers and operators
