Product Introduction

Hunan Saner SRSP35E/A9 is a high-pressure concrete wet-mix shotcrete truck specialized for tunnel lining, mining, and slope stabilization.

Products Features

The Kawasaki main oil pump delivers high-pressure hydraulic power, continuously pushing dense materials to minimize pipeline clogging.

The diesel-electric dual power system utilizes the diesel engine for chassis self-propulsion and switches to industrial electricity for high-pressure shotcreting.

Large-bore delivery cylinders paired with a wear-resistant S-tube valve lower cycle frequency to ensure a smooth flow of coarse aggregates.

The variable-frequency dosing pump works with compressed air to atomize accelerators efficiently, achieving precise stepless regulation and minimizing vertical rebound.

An open water box integrated with an independent air-cooled radiator maintains optimal oil temperature and allows prompt cleaning of delivery cylinders.

Components of Shotcrete Pump

Hydraulic system:

Closed-circuit energy transmission loop consisting of hydraulic pumps, control valves, and pipelines.

Drive cylinders:

Hydraulic actuators connected to the main pump that alternately push the concrete pistons.

Concrete cylinders:

Metal barrels beneath the hopper that move pistons back and forth to suck and push materials.

S-Tube Valve:
A wear-resistant distribution valve oscillating between twin concrete cylinder outlets inside the hopper.

Water box:

A water-filled chamber located between the drive cylinders and the concrete cylinders.

Hopper Agitator:

A mixing shaft with blades inside the feeding hopper, driven by a hydraulic motor.

Vibrating Grill:

A steel filtering mesh screen covering the top of the hopper, equipped with a hydraulic vibrator.

Technical Standards & Certifications

ISO 9001:2015: Covers the entire manufacturing process from raw material inspection to final pressure testing.

National IV Standard: The chassis engine complies with emission regulations, satisfying eco-conscious site access.

EN/ISO Interlock: The hopper grill cuts off mixing and pumping immediately once opened to protect operators.

FAQ

Q1: Why does this machine use an S-tube valve instead of a ball valve?

A: Engineering shotcrete requires coarse aggregate. Ball valves fail to pass 15mm stones and jam easily, making the S-tube valve the only choice.

Q2: How does the hardware prevent pipeline plugging on site?

A: It filters oversized stones via a vibrating screen, utilizes an internal agitator to prevent segregation, and relies on the heavy-duty force of the Kawasaki pump.

Q3: How is the accelerator dosage regulated during operation?

A: The unit features a variable-frequency dosing pump. Operators adjust the control knob on the panel to achieve precise, proportional chemical mixing.

Q4: How do you switch the dual power systems, and can the chassis drive independently?

A: The engineering chassis relies on the diesel engine for self-propulsion and climbing. Once positioned, it switches to the electric motor with a single button upon connecting to 380V power.
