The utility model, spacing is at least 2 meters between said pumping frame and the said power underframe, is communicated with through sebific duct between said pumps hydraulic system and the power station hydraulic system and supports through said oil tube bracket.
The utility model is provided with the space that can store waste oil and waste water between the crossbeam of said power underframe and the base plate, the bottom in said space is provided with outlet, in the said outlet purge cock is installed.
The concrete cylinder in the utility model, said pumping mechanism and the stroke of master cylinder are 3100mm.
Hopper in the utility model, said pumping mechanism adopts fast disassembly type independently double-stirring machine structure and bilateral door-opening mechanism.
Adopt the piston type industrial pump of technique scheme, the utility model has following advantage:
1, power system adopts two dynamical motor to form two groups of identical motor pump unit, and on the one hand, the separate unit motor power (output) reaches 400kW, and outlet pressure reaches 14MPa than the big 2～3MPa of general piston type industrial pump, and side's amount reaches 200m
3/ h; On the other hand; Two groups of motor pump unit are subsequent use each other, both can work simultaneously by two power, but also separate unit dynamically working; Further improved reliability and versatility, guaranteed in when work just in case one group of power unit cisco unity malfunction and need not shutting down with the filling slurry that guarantees pumping can not solidify and plugging causes tremendous loss.
2, the stroke of concrete cylinder and master cylinder reaches 3100mm, makes pumping side measure and can reduce the switching-over number of times in the unit time under the constant situation, reduces the wearing and tearing of distributing valve, also reduces the number of times of friction back and forth between concrete piston and casing wall, the working life of significant prolongation concrete piston.
3, the power chassis design has the space that can store waste oil, water; Waste oil that flows out from hydraulic oil container, cooling system and power system and waste water directly do not efflux and flow into the space in the power underframe; When the waste oil in the space and waste water are expired soon; Can purge cock be opened,, so more can protect environment waste oil and the unified discharge of waste water.
4, hopper adopts fast disassembly type independently double-stirring machine structure and the design of employing bilateral door-opening mechanism, and fast disassembly type separate double stirring mechanism can make material stir fully, has improved efficient.The bilateral door-opening mechanism adopts one-sided opening the door more to be prone to hopper is cleaned, maintains than common hopper, more is prone to installation, maintenance and waits component with replacing S pipe.
In sum; The utility model is a kind of high-power, high pressure, big pumping side amount and remote piston type industrial pump that carries out paste body filling of carrying of collecting; The problem of can fully solve the colliery surface subsidence, ploughing and destroying improves underground resources coefficient of mining and the purpose that reaches green exploitation.
