To ensure the reliability of the asphalt gear pump, it should be ensured that the power supply voltage is within the range of 15%-10% of the rated voltage, and it can work normally. And ensure that the valve body arrow should be installed with the same direction of flow, can not be installed in direct dripping or splashing water, the asphalt gear pump should be installed vertically. After the installation is completed, ensure that there is no reverse pressure difference in the pipeline so that it can be put into use after it is properly warmed. When the asphalt gear pump fails or is cleaned, a bypass device should be installed to ensure that the system continues to operate.

During the use of stainless steel bituminous gear pumps, attention should be paid to the following points: Dosing point pressure; Stroke frequency; Suction lift height; Altitude; Corrosion of chemicals. Asphalt gear pump reliability is mainly reflected in the factory test project, in order to ensure quality problems, should use the brand-name products of regular manufacturers; asphalt work standard: long-term work system, repeated short-term work system and short-time work system three, The conventional product is a long-term work system, which allows long-term power work. For long-term valve opening only short-term closure of the situation, and should use normally open asphalt gear oil pump. When used in a short-time work system and in large quantities, special orders can be made to reduce power consumption. When the operating frequency of asphalt gear pump is high and the operating frequency is high, the structure should be a direct-acting asphalt gear oil pump, and the power supply should be selected for exchange.

This guarantees the reliability of the asphalt gear pump!
