High temperature gear pump seal in the operation of the friction heat to seal the end face of the temperature rise, if not the appropriate measures, will have the following results: ①sealing between the liquid film vaporization, wear increased. ② moving, static ring heat distortion, resulting in increased wear and tear, increased leakage. ③ medium on the mechanical seal corrosion rate. ④ auxiliary seal aging, deterioration and failure. High-temperature gear pump gear, shaft, pump cover, shaft seal and other components, all parts are made of suitable temperature-resistant materials. Pump operating parts are transported using the media lubrication .KG pump with a safety Valve, to prevent overloading damage to the pump and motor Applications High-temperature gear pump (high temperature pump) for conveying solid particles and fibers, non-corrosive high temperature liquid medium temperature up to 250 ℃, the viscosity of 5-1500cst Uses High temperature gear pump is used in various industries such as plastic rubber processing industry, textile printing and dyeing industry, paint industry, wood processing industry, food industry, paper printing and other liquid heat carrier heating carrier heating transmission. 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. 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.
Self-locking nut is a nut widely used in machinery and other industries. Its working principle is self-locking by using the friction between nut and Bolt. However, the reliability of this self-locking will be reduced under dynamic load. On some important occasions, we will take some anti-loosening measures to ensure the reliability of nut locking.
