Start high-pressure clear water pump simultaneously in step (2) and high pressure mortar pumps the process sprayed by high-pressure nozzle are as follows: high pressure Fresh water pump extracts the water in scuttlebutt by high pressure clear water pipeline, and high pressure mortar pump extracts mortar stirring by high pressure mortar pipeline Mortar in bucket, makes the pressure registration of first pressure gauge be slightly less than the registration of second pressure gauge, certain density mortar enters It is blended in clear water in tee tube, by being sprayed outward after high-pressure jet pipeline by high-pressure nozzle.
By adopting the above technical scheme, the present invention has the following technical effects are as follows:
(1) present invention utilizes mortar stirring barrel, and concentration mixes under normal pressure according to a certain ratio for Jiang Shui, sand, then utilizes 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.
