Shear pump is usually used together with Jet mud mixing unit, to be assembled as a jet shearing unit in oilfield solids control system.
Jet shearing unit
The jet shearing unit is formed by shear pump, mixing hopper, pipeline and polymer/clay hydrator. For installation transportation, the polymer/clay hydrator is formed by a separate compartment.
The pump should be located the liquid source so that the suction line can be short and reduce loses. The foundation should be sufficiently rigid and substantial to absorb any vibration and support the base plate at all points. The base plate should be installed in a level position.
The JQB series shear pump adopts a set of compound seal for no leakage at stuffing box. Inside pump is a 300series stainless steel turbine containing 44 nozzles, four scoops and shear plate. Fifty(50)% of the fluid is sheared twice each time through the pump. This turbine shear pump is mounted on a special base with belts and sheaves to drive pump, OSHA type belt guard and a electric motor. Included is a special hopper(ZHP150) with nozzle sized for this application and one mud kit as a package in order to build a complete shear and hydration system. The pump is designed to give longer service life through the improved shaft seal.
There are many principles of proper pump installation and application as well as special considerations for the pump design which, if followed, will further enhance the performance of your shear pump.
This document will deal with both general and specific recommendations for improved JQB series turbine shear performance in both oilfield and industrial applications.
