To ensure the reliability of asphalt gear pump should be guaranteed in the supply voltage of 15% -10% of the rated voltage fluctuations within the normal work. And to ensure that the installation of the body arrow should flow with the media, can not be installed in a direct drip or splashing water, asphalt gear pump should be installed vertically up. After the installation is completed, to ensure that no reverse pressure in the pipeline to make it suitable for the temperature before formally put into use. When the asphalt pump gear failure or cleaning, in order to ensure the system continues to operate, the bypass device should be installed. Stainless steel pitch gear pump in use, should pay attention to the following points: dosing pressure; stroke frequency; suction height; altitude; chemical corrosion. Asphalt gear pump reliability is mainly manifested in the factory test items, in order to ensure quality problems, should be used formal brand-name products manufacturers; Asphalt gear pump work system: long-term work system, repeated short-term and short-term working system of three, Conventional products for long-term work system, that is, around the circle to allow long-term power work. For a long time the valve opened only a short time off, and should use normally open pitch gear pump. Used in short-time working system and the volume is very large, special orders can be made to reduce power consumption. Asphalt gear pump operating frequency, high operating frequency requirements, the structure should be preferred direct acting gear pump gear, power selected AC. This ensures the reliability of asphalt gear pump!
