2CY series gear pump for conveying solids and fiber-free, non-corrosive, the temperature is not higher than 200 ℃, the viscosity of 5-1500cst lubricating oil or other properties of similar lubricating oil and other liquids, and suitable for hydraulic transmission system. 2CY series gear pump purposes: In the oil transfer system can be used as transmission, booster pump. In the fuel system can be used as delivery, pressurization, injection fuel pump. In the hydraulic transmission system can be used as a hydraulic pump to provide hydraulic power. In all industrial areas, can be used for lubricating oil pump. 2CY series gear pump structural features: 2CY series gear pump mainly consists of gear, shaft, pump body, pump cover, bearing sleeve, shaft seal and other components. Gear and shaft are subject to strict heat treatment, high hardness and wear resistance, together with the shaft installed in the sleeve. All moving parts in the pump are lubricated with the medium they supply. Gear pump four bearing sleeve float installed in the pump body, with the work of pressure automatically adjust the size of the end interval, so the pump pressure stability, the output flow pulsation, volumetric efficiency. High-temperature gear pump polyester melt delivery, pressurization and melt measurement is essential equipment. Compared with other types of melt pumps, the high temperature gear pump has the advantages of compact structure, reliable operation, low energy consumption, high volumetric efficiency, small shear effect on the melt, stable flow at high viscosity and high pressure, and no outlet pressure fluctuation. The pump has its unique advantages and the key role in the process, making it play an irreplaceable role in polyester production. A complete gear pump includes a motor, reducer, coupling and pump head several parts, the pump head part of the pump housing, front and rear side cover, gear shaft, sliding bearings and shaft seal composition. High-temperature gear pump is a positive displacement pump, work rely on the main, driven gear changes caused by the work volume changes to transport the melt. Working volume by the pump body, gear tooth groove and the function of the side plate with the composition. When the gear rotates, the melt enters the tooth grooves of the two gears of the suction chamber. As the gear rotates, the melt is brought into the discharge cavity from both sides, and the gears mesh again to make the melt in the tooth grooves to be squeezed out Cavity, pressure delivery to the outlet pipe. As soon as the pump shaft is turned, the gear presses the melt down to the outlet side so that the pump outlet can reach very high pressure with little or no effect on flow and discharge pressure. (l) Pump disassembly and cleaning, heating, cooling, starting and stopping should be strictly in accordance with the provisions of the operation, in order to avoid undue losses. (2) Care should be taken to maintain the stability of the population pressure of the booster pump so that it has a stable volumetric efficiency in favor of the pump itself and the stability of the downstream spinning quality. (3) The population is negative pressure of the packing shaft seal pump, packing should be kept at a pressure higher than the atmospheric pressure. When the back pressure is reduced, the pressure of the stuffing box should be adjusted in time, otherwise the pump will be sucked into the air and the belt will be broken. This will affect the pelletizing and cause the discharge of the pelletizer. (4) to check the temperature of the heat medium jacket, the main body and the front and back cover of the heat medium temperature to be consistent. (5) Every time the output increases, it is necessary to record the output, speed, output, inlet pressure and current value at the time, and compare the data before and after, and carefully analyze them so as to find the abnormalities as soon as possible and deal with them in time.
