Concrete Pump
UB3C mortar pump produced by our factory is a plunger type mortar pump, which can transport 3m3 mortar per hour. It is a kind of engineering construction equipment with wide use.
In the application of prestressed construction technology, it can be used for precast members or cast-in-place members of the tunnel grouting. In the ordinary construction engineering, can be used for bridge, culvert, mine, tunnel grouting reinforcement, spraying support and internal and external walls, ceiling of the spray ash, plaster, in addition, in the chemical department, railway construction and other projects, can be used to transport slurry equipment.

1.Preparation before starting
(1)Check whether the connection parts are loose, whether there is enough oil in the gear box.
(2)Check whether the pump, pipe connection is sealed, whether the internal smooth, or the existence of dry gravel, dry ash, nails, vegetation, etc., ball valve, rubber hose is damaged.
(3)Check the wire, the fuse is intact, the motor steering is right (clockwise).
2.The use of mortar pumps
First with a white paste as a pipe lubrication, using the pump cylinder pressure transmission, and then drive into the more dilute mortar (consistency of 12 cm or more), and finally increased to the desired consistency, so as not to plug the pipeline, especially for the use of new pipes is more important. When using,open the pump first and then add mortar. (Consistency weighing 300 grams)
3.Precautions when using mortar pump
(1)When using,we should always pay attention to the work of the pressure gauge, when the working pressure is over, stop working. At this time should immediately open the pressure relief ball valve, so that pressure drop, eliminate the trouble and then restart and use.
(2)Should always check the connection hose, flange,asbestos cord,so that the pressure does not occur leakage.
(3)The cement paste should have sufficient fluidity and recommended for use with a fluidity tester. When the water-cement ratio of 0.4-0.45, the flow of 120-170mm, to meet the grouting requirements.Cement may not be doped with chloride, sulfide and nitrate.
(4)Mortar with sand should be screen, the maximum material diameter is not more than 5 mm.When using,should be mixing uniform, no dry sand, lumps, stones and other debris (such as: nails, vegetation, etc.).
