Abstract
The invention relates to a coal mine drilling device, in particular to a duplex-pump structural pump station of a drilling machine, wherein the duplex-pump structural pump station of the drilling machine serves as a hydraulic power source of drilling machine equipment. The duplex-pump structural pump station of the drilling machine comprises a motor, a duplex pump driven by the motor, and an oil tank used for storing hydraulic oil. The duplex pump is located in the oil tank. Two oil suction ports of two oil pumps forming the duplex pump are respectively and directly communicated with an inner cavity of the oil tank through a filter. Oil outlets of the two oil pumps are connected with a hydraulic oil way of the drilling machine through overflow valves outside the oil tank. According to the duplex-pump structural pump station of the drilling machine, the size is reduced greatly, complex connection and installation of a large number of connectors, rubber tubes and the like are omitted, and the evacuation phenomenon can be avoided effectively. In addition, the aspects such as use performance and use efficiency of the selected duplex plunger pump are improved greatly, higher reliability is achieved for a whole system, and selection of an oil pump of a conventional pump station is broken through.
Description
Technical field
The present invention relates to a kind of colliery drilling equipment, specifically a kind of double pump structure pumping plant of the rig as drilling equipment hydraulic power supply.
Background technology
The pumping plant of drilling equipment is mainly comprised of parts such as motor, oil pump, fuel tank, overflow valve, smart coarse oil filter, cooler, air filter and bases.Pumping plant is to rotate by electric motor driven oil pump, converts electric energy to hydraulic energy (pressure oil), and oil pump is from fuel tank oil suction pressure oil output.The pumping plant of rig has the pumping plant of duplex gear pump form of structure, the form of structure such as pumping plant that oil pump connects by belt pulley both at home and abroad at present.
The pumping plant of duplex gear pump form of structure rotates by electric motor driven oil pump, converts electric energy to hydraulic energy.The pumping plant of this structure work in because the not high overall efficiency that causes of efficiency of gear pump own is on the low side.And such operation of oil pump life-span is limited, fault rate is improved, strengthen the workload of coal miner, affect job schedule.The mode that this pumping plant generally adopts oil pipe to connect, because be subject to the restriction of form of structure, in disorder in line arrangement, not rigorously in operation cause most probably emptying phenomenon, thereby gear pump is broken down, cannot work.
The pumping plant that oil pump connects by belt pulley rotates by electric motor driven oil pump equally, converts electric energy to hydraulic energy.The pumping plant volume of this structure is larger, easy to install and use under the specific environment in colliery; Before size pump, by belt, carry out transferring power, belt runs up and has certain potential safety hazard, to operator, makes troubles.And the efficiency of belt connection form is not high yet.In addition, belt belongs to consumable accessory, needs periodic replacement, affects work and progress.
Summary of the invention
Technical problem to be solved by this invention is, the double pump structure pumping plant of the rig that provide a kind of compact conformation, volume is little, operational reliability is high, the cycle of operation is long.
The double pump structure pumping plant of rig of the present invention includes motor, by motor-driven duplex pump, be used for the fuel tank of storage liquid force feed; Described duplex pump is positioned at fuel tank, and the inlet port that forms two oil pumps of duplex pump directly communicates with fuel tank inner chamber by strainer respectively, and the oil-out of described two oil pumps is connected through the overflow valve of fuel tank outside and the hydraulic circuit of rig.
Two oil pumps of described composition duplex pump are plunger displacement pump.
The present invention has utilized the inner space of fuel tank fully, duplex pump is placed in one, not only significantly dwindled equipment volume, and in equipment running process, oil pump saves loaded down with trivial details connection and the installations such as a large amount of joints, sebific duct by the direct oil suction of oil filter, and effectively avoided emptying phenomenon; In transportation, consider the complex work environment of coal mine underground equally, play a very good protection; In addition, the aspects such as functional performance, service efficiency that are chosen in of duplex plunger displacement pump are largely increased, and whole system also possesses higher reliability, has broken through the selection of conventional pump station oil pump.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention;
Fig. 2 is the plan structure schematic diagram of Fig. 1.
The specific embodiment
As shown in the figure, the duplex pump structure pumping plant of this rig include motor 1, by motor-driven duplex pump 2, be used for the fuel tank 3 of storage liquid force feed; Described duplex pump 2 is positioned at fuel tank 3, and the inlet port that forms two oil pumps of duplex pump 2 directly communicates with fuel tank inner chamber by strainer 4 respectively, and the oil-out of two oil pumps is connected with the hydraulic circuit of rig through the overflow valve 5 of fuel tank outside.Two oil pumps that form duplex pump 2 are plunger displacement pump.
Claims (2)
1. a duplex pump structure pumping plant for rig, include motor (1), by motor-driven duplex pump (2), be used for the fuel tank (3) of storage liquid force feed; It is characterized in that: described duplex pump (2) is positioned at fuel tank (3), the inlet port that forms two oil pumps of duplex pump (2) directly communicates with fuel tank inner chamber by strainer (4) respectively, and the oil-out of two oil pumps is connected with the hydraulic circuit of rig through the overflow valve (5) of fuel tank outside.
2. the duplex pump structure pumping plant of rig according to claim 1, is characterized in that: two oil pumps that form duplex pump (2) are plunger displacement pump.
