TRJQB6545 Shear Jet Mixing Devices Enter the Shield Construction Site Again

The TRJQB6545 shear mixing devices produced by TR have been put into the shield construction site again.

Shield machine is a kind of special construction machinery for tunnel excavation. Modern shield tunneling machine integrates optical, mechanical, electrical, hydraulic, sensing and information technology. It has the functions of excavating and cutting soil, conveying soil ballast, assembling tunnel lining, surveying and guiding deviation correction. It involves many disciplines and technologies such as geology, civil engineering, machinery, mechanics, hydraulic pressure, electricity, control, measurement and so on The geological design and manufacturing of “tailor-made” style, the reliability requirements are very high. Shield tunneling machine has been widely used in subway, railway, highway, municipal, hydropower and other tunnel projects. The shear mixing device produced by Xi’an Tianrui is mainly used for slurry pressure shield. A large amount of slurry is needed in the construction process, and the composition of the required slurry varies according to different working conditions. Therefore, it is necessary to use the shear mixing device to mix the slurry. Through the slurry shear mixing device, the added materials can be more fully fused with the slurry.

The mixing device of mud shear pump is composed of the main body of the shear pump and the shear funnel, which can provide high shear for the rapid hydration of polymer (and clay). The use of the shear mixing device can reduce the amount of polymer by more than 15% and the amount of bentonite by more than 30%. It also improves the loss of mud cake and fluid flow, reduces the shear ratio rate of drilling fluid, and increases the shear rate of drilling fluid Gel strength;
Xi’an Tianrui is a professional mud separation equipment manufacturer. The shear mixing device is one of the equipment in the shield slurry treatment system produced by the company. The company can provide a complete set of shield slurry separation system for the shield construction. If you need slurry separation, you can contact at any time.
