Description

wet concrete shotcrete pump concrete spraying machine

Instruction:

Saintyol DAWIN wet concrete shotcrete pump or say spraying machine are manufacturing 3 models: DSPJ08 diesel or electric power small output 8m3/hr volume model, QKSP-20 robot shotcrete pump in 20m3/hr output capability and truck chassis model QHP30A robot shotcrete truck with 30m3/hr output capability.

Wet concrete shotcrete pump output can be adjusted continuously, main oil pump is variable displacement plunger pump, spraying volume could be adjusted freely. Accelerating adding quantity could be adjusted continuously: according to spraying volume adjust step-less. Saintyol DAWIN Equipment self-lubrication system for the wet shotcrete machine to automatic lubrication for main sealing parts, thus could lengthen wearing parts working life greatly

Saintyol DAWIN wet concrete spraying machines used for wet concrete spraying in mining, tunnel, culvert, metro, hydropower engineering, underground construction, slope protection etc. or for filling, grouting pump concrete mortar etc.

Features:

The system is more reliable and delivery capacity is stable in adopting hydraulic pumping.

It has large volume of delivery, long distance of delivery and high efficiency of construction.

Sprayed concrete is of high performance and strength, as well as being dense and homogeneous.

,PLC.

The main oil pump adopts variable displacement piston pump of constant power; and the delivery amount, which can be freely adjusted according to needs, is controlled by PLC.

S pipe surfacing electrode of high strength, wear plate and cutting ring are inlaid with hard alloy of high strength, which not only improves the wear resistance, but increases the service life of parts.

It is equipped with multi-point electric lubricating pump. And together with automatic and effective control of grease's filling amount and time, contributing to the fact that the service life of wear-out parts are effectively increased

Air cooling avoids damage caused by water cooling in winter.

Accelerator is added and controlled by metering pump of domestically famous brand, achieving accurate measurement and realizing stepless speed regulation.

Harm on the health of operator is reduced by lowering dust concentration beside the machine and of the nozzle.

Humanized design of product makes operation and maintenance become easier, with reliability effectively guaranteed as well.

Areas of application:

The SAINTYOL DAWIN Machinery wet concrete shotcrete pump are based on technical pioneer achievements. They keep researching and developing new technology - and have been doing so for many years!They are the national initiative equipment for fine stone concrete conveying and won two national patents.

·Fine stone concrete conveying

·Floor heating construction

·Tunnel and underground construction

·Mortar conveying

·Used as spray pump when Installed with incidental spraying equipment, for concrete, mortar, refractory material and green soil spraying

DSPJ08-07-56 wet concrete shotcrete pump are applied for high-rise conveying, railway, tunnel, bridge construction and special applications, hydraulic power, mining and national defense.

Main Parts:

Electric Motor

Name: BEIDE Motor

Brand: Semens

Original: Germany

Famous engines at home and abroad, Yantai Motor and Beide Motor of Siements. which have a strong driving force, low fuel consumption and high efficiency.

Diesel engine

Brand: Tianjin LOVOL/ Yuchai /Weichai/Cummins

Diesel engine adopts Tianjin LOVOL or Yuchai or Weichai or Cummins as custom request, which has low energy consumption and high efficiency

Pumping System

Concrete pump pumping system is the core technologies of Saintyol DAWIN Machinery,

DN140mm, 180mm, 200mm and 230mm large diameter cylinder, absorb good, pumping large displacement.

Main Oil Pump

Main oil pump adopts joint venture brand constant power variable plunger pump. Constant power control is effective to prevent the electromotor or diesel engine form overloading. It can withstand higher pressure and load than ordinary gear pump.

Centralized lubricating system

The lubricant will be injected to the main oil line by the plunger pump and distributed to each lubrication point by the distributor. Point-to-point lubrication protects main components from wear and tear.

Cooling System

It adopts dual-cooling system, with cooling and water cooling, not only for hot climate but also for cold climate; it can effectively control the oil temperature of hydraulic system and ensure the safety and reliability

Hydraulic pipe joints

Hose joints: American Eaton; Pipeline: Original from Italy.

A set of these supported by Eaton.

S Valve

Brand: joint venture brand

Original: Germany

S tube valves are cast into shape with austenitic manganese steel, the quick wearing surface is welded with wear-resistant material, has dual advantages of anti-high pressure and anti-wearing.
