Product Introduction

Hydraulic grouting pump is a fully hydraulic,adjustable pressure grouting pump. The use of high pressure pump is easilysolidified substance or mixture (water, mud, water glass, etc.) of the rock orsoil cracks and cavities accurate injection order to reduce leakage, rock andsoil consolidation purposes.

Hydraulic grouting pump is widely used for coal,underground water well construction and engineering, but also for tunneling andmaintenance, construction of dams, large bridges, high-rise buildings andvarious underground foundation treatment works.

Structure and working principle

Hydraulic grouting pump consists of motor, gearpumps, pressure relief valve, hydraulic valve block, cylinder, cylinder, mixersand tanks, radiators, oil filter, intake and exhaust valves and electricalcontrol box and other components.

Motor direct drive gear pump, gear pump outputpressure relief valve into the hydraulic fluid through the valve block, thehydraulic valve block control cylinder reciprocating motion, as cylinders andcylinder are synchronized movement, because of the working cylinder bore andstroke are the same, so the working cylinder and cylinder displacement andstress basically similar to each end of the cylinder valve and the exhaust setgrout slurry valve, which can be the same kind of slurry suction, suction canbe respectively two different the slurry.
