Efficient operation,Economic choice,Stable performance,The installation and operation is simple,Safe and reliable,Multi-function

Structure:

1.a pump body

2.a vacuum pumping pipe

3.water circulation system

4.negative pressure container

5.a flushing pipeline

6.a frame part

As the power source,  the liquid ring vacuum pump and a vacuum pressure gauge, an integrated power switch and a power indicating lamp all assembly in a compact box body.

Working principal:

MBV80 Type vacuum pump is a forming equipment through pressure of post-tensioned prestressed duct  vacuum grouting.

Step1:Connecti the vacuum pump and one end of good-sealing prestressed duct before grouting to post-tensioned prestressed duct

Step2:Starting,making the inner of duct reaching -0.06~-0.1 MPa negative pressure and holding.

Step3:Grouting from another end of prestressed duct until the entire channel filled with cement slurr.

Specifications and models meaning:

MBV80

M means used for prestressing

B means pump                                                                                  

V means vacuum

80 means pumping 80 cubic meters per hour.

Advantages:

Through the function of vacuum negative pressure

1.It can reduce water and cement ratio of the cement slurry for perfusion

2.eliminate pore and mixed in cement slurry bubble

3.reduce porosity and bleeding phenomenon

4.guarantee the grouting fullness,compactness and strength

5.This type of  vacuum pump with HDPE plastic corrugated pipe and a screw type filling machine can achieve very good grouting effect

6.can work with ordinary metal bellows formation pore and good performance of the piston mortar pump .
