When the valve is opened for a long time and only closed for a short time, the normally open
asphalt gear pump should be selected. And ensure that the installation of the body arrow should be consistent with the flow of the medium, not installed in a direct drip or splash of water, asphalt gear pump should be installed vertically upward. Asphalt gear pump reliability is mainly shown in the factory test project, in order to ensure the quality of the problem, should choose regular manufacturers of famous products; The working system of asphalt gear oil pump is divided into three kinds: long-term working system, repeated short-term working system and short-term working system. Conventional products are long-term working system, that is, the circle allows long-term electricity work. In short time working system and large batch, can make special order to reduce power consumption. After installation, ensure that there is no reverse pressure difference in the pipeline, so that the proper temperature can be formally put into use. When the asphalt gear pump fails or is cleaned, the bypass device should be installed to ensure that the system continues to run.
When the working frequency and action frequency of asphalt gear oil pump are high, the structure of direct acting asphalt gear oil pump should be preferred, and the power supply should be AC. This ensures the reliability of asphalt gear pump! Stainless steel asphalt gear pump in the use of the process, should pay attention to the following points: add pressure; Stroke frequency; Suction height; Altitude; Corrosivity of chemicals. To ensure the reliability of asphalt gear oil pump, it should be guaranteed to work normally within the fluctuation range of 15%-10% of rated voltage of power supply.
