Description
Technical field
The utility model relates to long-range supply equipment, particularly a kind of long-range supply equipment that is used for fire-fighting fire extinguishing in the time of petrochemical zone generation large-sized fire.
Background technology
At present, in the Fire Control System Design of petrochemical zone (refinery or storage), with the summation design fire-fighting water yield of the maximum water consumption of fire-fighting and the auxiliary temperature-reducing water yield, the fire-fighting fire extinguishing time (fire hydrant and fire monitor) is 6 hours conventionally.But in actual fire-fighting, particularly liquefied gas or product oil storage field, often cause blast once on fire, can cause many places fire, the fire-fighting water yield of the fire-fighting system of reservoir area can only be often to meet the time that fire fighter arrives and prepares, and because the moisture storage capacity of fire fighting truck is limited, again continue water source for fire-fighting fire extinguishing or maintain passage cut off.In a lot of situations, wait combustible that can only the be helpless flame automatic distinguishing that burnouts, causes huge loss and environmental pollution.Can there is when making breaking out of fire sufficient water source to use in order to fire-fighting and the water needs of refinery own or storage, at present, the construction of petrochemical zone can consider to close on the water head sites such as river, river, lake, sea, reservoir, in the time of breaking out of fire, can put out a fire and cut off by the water at the equipment extraction water sources such as trailer pump.But due to water pump characteristics, the suction capacity of water pump is subject to atmospheric pressure to only have the impact of 0.1MPa and cavitation (in, general large pump suction capacity can not exceed 5m, and self-priming pump lift is all lower.And the banks such as river, river, lake, sea, reservoir, the position that its trailer pump can arrive and the drop of horizontal plane are often higher again, common trailer pump is difficult to be drawn onto water, even if suct water and also can not send because of serious cavitation erosion the effect of water, cannot accomplish that large flow supplies water.
Utility model content
The purpose of this utility model is to solve the problem that above-mentioned prior art exists, and provides a kind of long-range supply equipment that can adapt to high drop water supply needs, to realize, remote the continuing at the large-sized fire scenes such as petrochemical zone is supplied water.
Long-range supply equipment described in the utility model, comprises walking dolly, and engine, force (forcing) pump, engine cooling apparatus and water tank are installed on walking dolly; One end of engine crankshaft connects the pump shaft of force (forcing) pump by shaft joint, the other end of engine crankshaft drives pump shaft to rotate by the pump shaft of shaft joint connecting fluid press pump; Engine cooling apparatus comprises hydraulic oil fan and cooling fluid pipeline, and hydraulic pump, by oil circuit connecting fluid force feed fan, drives hydraulic oil fan running; Hydraulic pump, also by water pump under oil circuit connecting fluid, drives water pump running under liquid; Under described liquid, on water pump, float is installed, when under liquid, water pump is placed in water, the buoyancy of float can make under liquid on water pump is bubbled through the water column; The outlet pipe joining water box of water pump under liquid, also joining water box of the water inlet pipe of force (forcing) pump.
Long-range supply equipment described in the utility model, when breaking out of fire, equipment can move near water source by dolly, water pump under liquid is directly thrown in water source, under the effect of float buoyancy, under liquid, water pump swims on the water surface, now connect water pump under hydraulic pump and liquid, will fetch water from underwater by water pump under hydraulic pump drive liquid, water is pumped in water tank, and engine-driven force (forcing) pump, the water again hydraulic pump being pumped in water tank again pressurizes and pumps.As long as force (forcing) pump outlet connects sufficiently long fire extinguisher canvas hose, can, by fire water from the pump at water source to scene of fire, realize the sustainable supply of fire demand water.
Described long-range supply equipment, fetches water by submerged pump, and force (forcing) pump adds the mode of force feed water, has adapted to cleverly high water level drop and has sent water.And its engine has been realized double dynamical output, engine crankshaft one end drives force (forcing) pump, the other end drives hydraulic pump, drive water pump under hydraulic oil fan and liquid by hydraulic pump, an engine has been realized the driving of the running to all devices simultaneously again, simple in structure, cost is low.
figure of description
Fig. 1 is the structural representation of long-range supply equipment described in the utility model.
Detailed description of the invention
As Fig. 1, a kind of long-range supply equipment, comprises walking dolly 1, and engine 2, force (forcing) pump 3, engine cooling apparatus 4 and water tank 5 are installed on walking dolly.One end of engine crankshaft connects the pump shaft of force (forcing) pump by shaft joint, the other end of engine crankshaft, by the pump shaft of shaft joint connecting fluid press pump, drives pump shaft to rotate, and hydraulic pump is directly fixedly installed in a side of engine.Engine cooling apparatus 4 comprises hydraulic oil fan 41 and cooling fluid pipeline 42, and hydraulic pump 10, by oil circuit connecting fluid force feed fan, drives hydraulic oil fan running.Hydraulic pump, also by water pump 7 under oil circuit connecting fluid, drives water pump running under liquid.Float 8 is installed on water pump 7 under described liquid, and when under liquid, water pump is placed in water, the buoyancy of float can make under liquid on water pump is bubbled through the water column.Water tank is also installed on walking dolly, and the outlet pipe joining water box of water pump 7 under liquid, pumps into subsurface water source water in water tank, and force (forcing) pump connects water tank by water inlet pipe, and the water pressurization in water tank is pumped.
Hydraulic pump also can connect walking dolly by oil circuit, rotates by the wheel shaft of hydraulic pump drive walking dolly.Meanwhile, between shaft joint and force (forcing) pump, be provided with clutch 6, clutch one end connecting engine bent axle, the other end connects the pump shaft of force (forcing) pump, and when clutch is closed, engine crankshaft can drive force (forcing) pump running, when throw-out-of clutch, engine crankshaft and force (forcing) pump are thrown off.Move in water head site process at walking dolly, engine crankshaft and force (forcing) pump are thrown off, and engine does not drive force (forcing) pump, only drive hydraulic pump, rotate by the wheel shaft of hydraulic pump drive walking dolly, the walking that realizes dolly drives, avoid the idle running of force (forcing) pump, save the energy.
Shaft joint 9 between engine crankshaft and clutch 6 can be elastic pin shaft connector, elastic pin shaft connector 9 can provide certain radial deflection space, thereby can adapt to long-range supply equipment running time, radial deflection between engine crankshaft and clutch with beat, avoid the equipment damage therefore causing.
