Hydraulic Double Cylinder Grouting Machine
The Hydraulic Double-Cylinder Grouting Machine utilizes a double-cylinder, double-acting hydraulic drive system. An electric motor powers a gear pump to generate hydraulic pressure, while an electro-hydraulic directional control valve regulates the two working cylinders to perform alternating reciprocating movements with a 180° phase difference; as one cylinder discharges grout, the other simultaneously performs the intake stroke. This ensures continuous, high-pressure grout delivery without pulsation, achieving a volumetric efficiency exceeding 95%.
Key components of the machine include the motor, gear pump, relief valve, hydraulic directional control valve block, drive cylinders, working cylinders, heat exchanger, and grout intake/discharge valve assemblies. The drive cylinders and working cylinders are synchronously linked via a common shaft, allowing for the stepless adjustment of displacement and pressure within the design range.
Double Cylinder High Pressure Cement Grouting Machine for Construction Projects
Choosing a double cylinder high pressure cement grouting machine often starts with a practical question: which model will meet the project’s requirements? Construction companies need a clear product catalogue, detailed specifications and an understanding of how the equipment will handle their grout and site conditions.
A recent enquiry highlights this need. A construction company contacted us looking for a double cylinder cement grouting machine and requested a catalogue to compare available products. For buyers with similar requirements, the selection process should connect equipment specifications with the actual injection work.
Matching the Machine to the Application
A hydraulic double cylinder grout pump can supply compatible cement-based grout for foundation treatment, tunnel grouting, anchor installation and structural void filling. Each application places different demands on the equipment.
For foundation and rock grouting, adjustable delivery helps operators respond to changing grout intake within the project’s specified limits. In anchor and soil nail applications, pump selection depends on grout consistency, hole depth and delivery line length. For tunnel lining void filling, controlled placement and adequate supply are important, with injection pressure kept within the structure’s allowable limits.
High pressure capability provides operating capacity for demanding delivery conditions, but the selected pressure must suit the application. Pipeline resistance, elevation and grout properties all affect the pressure required at the pump.
Specifications to Compare in a Product Catalogue
When reviewing a cement grouting machine catalogue, consider the following details:
1. Output at the required pressure: Check the available delivery rate under the intended operating conditions. Maximum flow and maximum pressure should not be assumed to occur simultaneously.
2. Grout compatibility: Confirm the permitted material type, particle size and consistency.
3. Drive and power requirements: Match the equipment to the electricity or other power source available on site.
4. Inlet and outlet connections: Ensure compatibility with the grout supply system, hoses and injection equipment.
5. Dimensions and weight: Check transport, lifting and installation requirements.
6. Cleaning and maintenance access: Consider how the pump will be flushed and serviced between operations.
A Hydraulic Double Plunger Pump Option
The Lead Equipment LGM90/100PLD-E is a skid-mounted hydraulic double plunger grout pump with a specified output range of 0–90 L/min, a pressure range of 0–100 bar and a 15 kW motor. Stepless flow and pressure adjustment allows the delivery settings to be matched to different stages of grouting.
The pumping assembly uses 85 mm plungers with a 190 mm stroke. Its specified maximum particle size is 8 mm, subject to material suitability. The unit measures approximately 1,300 × 960 × 1,750 mm and weighs 770 kg, providing concrete information for site layout and handling plans.
Mixing and holding equipment should be selected alongside the pump to maintain a consistent supply of prepared grout.
