5) the stop valve b3 that cleaning is dredged on the b2 of plugging road is opened in remote control, and the abrasive material of residual in transfer pipeline is cleared up,
To prevent from remaining the blocking forming the extremely difficult cleaning of pipeline after alluvial.Medium in transfer pipeline b12 (transparent hose) becomes clear
Afterwards, close the stop valve b3 that cleaning is dredged on the b2 of plugging road, complete the conveying operation of compound abrasive.
5. water sand compound abrasive long distance delivery system
Below in conjunction with the accompanying drawings 1,2,5a, 5b, the work process of whole water sand compound abrasive long distance delivery system is done into
One step explanation:
1) sand and pressurising are added
Remotely closed by electric control system 4 and dredge cutting on the b2 of plugging road with the thin cleaning being connected of blocking up of threeway b10
Only valve b3；
Open the fast-open type sealing flange 5 that hydraulic pressure supplies silo 1, opened at transition case discharging opening 9 by electric control system 4
Sand supplying valve a13, from plus sandbox 7 carry out plus sand for silo 1 to hydraulic pressure through transition case 8, until hydraulic pressure reaches for the sand amount in silo 1
20-70% to its volume；Close sand supplying valve a13, close hydraulic pressure and supply the fast-open type sealing flange 5 at silo 1 material receiving port；
Open hydraulic circuit valve 6, open pressurization process pump 3 or pressurization flow process pump group, supplied to hydraulic pressure by hydraulic circuit 2
Water-filling in silo 1, makes persistently to possess 8 kilograms about pressure in tank, now package unit completes to be prepared to enter into working condition.
2) remote sand supplying
When production system needs to carry out sand supplying, by electric control system 4 remote opening first outlet controlling organization b1
In the two-way cylinder of the second drive mechanism b7, two-way cylinder drives motor and conical surface valve element b5 action, opens in discharge control valve
Water sand compound abrasive outlet, now first outlet controlling organization b1 is in opening, then pass through electric control system 4 remote
Cheng Kaiqi first drive mechanism b9 is motor, and motor drives rotary needle b6 in conical surface valve element b5 to be rotated, and hydraulic pressure supplies silo 1
Interior water sand compound abrasive enters first outlet controlling organization b1 in the presence of pressure inside the tank, and the conveying supply starting abrasive material is made
Industry, simultaneously because the rotation of rotary needle b6 and realize the choke preventing function of first outlet controlling organization b1；
3) as occurred surprisingly to cause transfer pipeline to block in operation process, Remote stops the action of motor at once, and
Starting two-way air cylinder driven conical surface valve element b5 makes it compress the sealing surface of valve seat b8 to close outlet, then opens cleaning and dredges plugging
Stop valve b3 on the b2 of road, is dredged to the pipeline of blocking using press water, until pipeline recovers unobstructed, turns off threeway
Stop valve b3 on b10, restarts two-way cylinder pull-up conical surface valve element b5, and starter motor recovers abrasive material conveying operation；
4) after the completion of conveying operation, closing motor makes rotary needle b6 stop the rotation, and starts two-way air cylinder driven conical valve
Core b5 compression valve seat b8 is to close outlet.
5) the stop valve b3 that cleaning is dredged on the b2 of plugging road is opened in remote control, and the abrasive material of residual in transfer pipeline is cleared up,
To prevent from remaining the blocking forming the extremely difficult cleaning of pipeline after alluvial.Medium in transfer pipeline b12 (transparent hose) becomes clear
Afterwards, close the stop valve b3 that cleaning is dredged on the b2 of plugging road, complete the conveying operation of compound abrasive.
