Rotating jet method grinding instrument

1、 Product Introduction:

Rotating jet method grinding instrumentIt is a high-speed centrifugal erosion testing machine designed according to the technical requirements specified in the "Technical Code for Epoxy Resin Mortar DL/T5193-2004" and "Technical Code for Anti scouring and Anti erosion Concrete of Hydraulic Structures DL/T5207-2005". It is used to measure and qualitatively compare the wear resistance of epoxy mortar under high-speed sand containing water flow erosion. It is similar to the natural environment of water or water sand erosion experienced by hydraulic structures, with intuitive testing, high erosion efficiency, strong practicality, convenient and durable operation. It is an ideal testing equipment for construction research, design and teaching.

4、 Product features:

1. Three sets of specimens can be tested at once, with three pieces in each set, and the instrument utilization rate is high.

2. The high water pressure provided by the narrow rectangular tube and water pump at the outlet ensures that the water and sand flow is evenly distributed during the flushing of the specimen, without leaving varying depths of marks on the specimen, ensuring the rationality of the flushing results.

3. The overall structure design is compact, the links are firm, and there are buffering components at the contact points. The noise and vibration during operation are relatively low.
