High pressure mortar pump, it is clear to be injected into the high pressure after being inputted out by high-pressure clear water pump for the water sand mixed flow (high-concentration mortar) of high concentration
In water lines, after high-concentration mortar is mixed with high pressure clear water, become the abrasive material mortar of suitable concentration, via high-pressure jet pipeline from
High-pressure nozzle sprays.Thus the continuous plus sand of front mixing abrasive water jet is completed；
(2) high pressure mortar pump is activated individually, the little cutting of water jet flow is suitable for by high-pressure nozzle injection, in addition also want
Prepare the concentration (water sand proportion) of suitable mortar；
(3) start high-pressure clear water pump simultaneously and high pressure mortar pump sprayed by high-pressure nozzle, the cutting for being suitble to water jet flow big,
Continuously add sand in cutting process, improves the effect and efficiency of water jet cutting.
(4) high-pressure clear water pump can be with this using the pump replacement of coal mine Emulsion.
(5) present invention can cleverly be carried using high pressure mortar pump small using high pressure mortar pump and pipeline control system
The characteristics of abrasive material particles sand, mixes present water, sand in a high voltage state, becomes Jiang Shui, sand is mixed under normal pressure state
Then high-concentration mortar is mixed into the high-pressure grinding material water jet of suitable concentration with high pressure clear water again, realize and conveniently, continuously add
Sand, it is easy to operate practical, it is at low cost, it is easily converted into matured product and quickly puts goods on the market.
