RT-722D Pumpability Capillary Rheometer
RIGHT combines the U.S. standard ASTM D1092 and domestic capillary rheometer for integrated and innovative instrumentation, which greatly improves the overall performance of shield tail sealing grease and provides effective testing equipment for further product development. Under the specified conditions, the flow rate of grease through a certain aperture capillary tube, expressed in g/min. Accurate equipment than the butter gun only qualitative and not quantitative. Provides an effective solution to compare the pumpability difference of different brands of grease and monitor the stability of different batches of products in our factory. Provide theoretical support to change the formula for different seasons in different regions.

The Shield Tail Seal Grease Pumpability Capillary Rheometer is used to test the pumpability of shield tail seal grease for construction shield machines.
As a kind of sealing material injected into the wire brushes of the tunnel shield machine for underground engineering shield construction, shield tail sealing grease mainly plays the roles of lubrication, sealing and waterproofing. It is injected into the inter-hole gap of the wire brush by pressure, which enhances the sealing performance of the wire brush. Therefore, the pumpability and adhesion of grease are very important indicators.
