Among them, at different pressures The flow rate and the ratio of the two components are the most important parameters of the grouting pump. Once there is an error in the ratio, it will seriously affect the entire production operation. Therefore, the detection of the performance of the grouting pump is to ensure the normal operation and stability of the equipment. Necessary means, if not tested, there will be serious errors.
目前，现有的双液注浆泵的测试装置只有一套测试系统，只能对双组份注浆泵的总流量测试，或者分别对每个工作缸流量的单独测试，工作效率低，同时因为两个工作缸不能同步进行，则检测人员在对不同缸进行检测时，往往存在检测误差，检测数据不准确，实用性差。At present, there is only one test system for the existing double-liquid grouting pump testing device, which can only test the total flow rate of the two-component grouting pump, or test the flow rate of each working cylinder separately, and the work efficiency is low. Because the two working cylinders cannot be carried out synchronously, detection personnel often have detection errors when detecting different cylinders, the detection data is inaccurate, and the practicability is poor.

During the test, it is generally necessary to test the flow of different pressure states, and generally test gradually from low pressure to high pressure. At the end of the test, the grouting pump is in high pressure delivery At this time, the bypass pressure relief valve should be opened to release the pressure of the grouting pump. If the pressure regulating valve is released in an instant, it is easy to cause damage to the subsequent flowmeter due to the large pressure difference. A one-way valve is installed on the branch pipe connecting the separate detection pipeline and the pressure relief pipeline to prevent the liquid from flowing between the two detection pipelines, resulting in inaccurate testing.
