Description

Technical Field

[0001] The utility model relates to the field of a two-component quantitative embolic pump, in particular to a two-component quantitative plunger pump. Background Art

[0002] A metering pump is a pump whose output flow rate is variable under the condition of constant speed, and a variable displacement pump is a pump whose output flow rate is variable under the condition of constant speed. The biggest difference between them is that the shaft of the variable displacement pump is eccentrically installed. Simply put, after the speed of the metering pump is selected, its flow rate cannot be adjusted. The output flow rate of the variable displacement pump can automatically adjust the flow rate according to the pressure change of the system (the size of the external load), that is, the output flow rate is small when the pressure is high, and the output flow rate is large when the pressure is low. In this way, it can save the number of hydraulic components, thereby simplifying the oil circuit system and reducing oil heating. During the glue filling process of the existing embolic pump, the embolic pump has a large quantitative error of the glue, which will cause glue waste. Based on this, it is necessary to provide an embolic pump that can perform precise quantitative measurement and reduce cost loss. In addition, the existing embolic pump has weak sealing, so it may cause glue leakage and damage to the embolic pump during use. Based on this, a method is provided to enhance the sealing of the embolic pump, thereby enhancing practicality and extending the service life of the embolic pump. Utility Model Content
