Pressure Stabilization Silo

DimensionsΦ1420×H4200 mm

Capacity2.5 m³

Hydrostatic Test Pressure 0.3 Mpa

Design Pressure0.2 Mpa


During cementing operations, if the distance between cement silos and mixers is too long, bulk cement will separate from the conveying flow and cake, which will cause pulse flow. The pressure in the silo decreases with the conveying of bulk cement. Pressure changes will result in bulk cement conveying fluctuation which leads to conveying discontinuity when reversing the silo and directly affects the slurry density and mixing equipment accuracy. In order to settle the problems above, a pressure stabilization silo is needed between the cement silo and the mixing equipment for buffering and pressure stabilization. The stabilized pressure can ensure the smooth conveying of bulk cement to effectively reduce the pulse fluctuation during conveying and cement dust generated in the mixer.

This equipment featuring compact structure and beautiful appearance mainly consists of the silo body, vent cover, air charging port, flange, substructure, inlet pipe, discharge pipe, pressure stabilization valve, safety valve, pressure gauge and lugs. This equipment is usually placed on the well site and serves to balance the cement silos pressure.

This equipment is applicable for onshore and offshore operations. All supplied parts are suitable for humid, storm and sand ambient environments that varying from -20~+45 ℃. It is especially applicable for cementing operations with critical requirements of slurry.

The dynamic analysis and calculation of the moving track of air inside the silo is performed based on the application performance of each part. The maintenance ladder is installed outside the silo for convenient inspection and repair of the parts inside.

Each pressure stabilization silo outlet is equipped with a valve the lining of which employs wear-resistance rubber that optimizes the open/close and seal of the valve.

This equipment features excellent conveying capacity, high discharge rate and less discharge residue. The horizontal conveying distance is 5~15m, and the vertical conveying distance is 6m. Under the working circumstance where the pressure is 0.12 MPa, the average discharge rate is no lower than 1.5t/min and the discharge residue is lower than 0.3%.

The equipment adopts an oval type roof. Compared with a cone-roof silo, an oval-roof silo has better mechanical performance, larger capacity, lower centroid and better stability. In the same working situation, an oval roof designed silo is safer than a cone-roof one.Inquire Now
