Abstract
The utility model discloses a radial plunger high-pressure water pump which is matched with the hydraulic devices of a hydraulic rock drill, a hydraulic crashing pick, etc. The radial plunger high-pressure water pump adopts a single row of centripetal ball bearings as stators assembled in a pump body, and rotors are provided with a plurality of plunger pistons in a radial direction. The top portions of the plunger pistons are in arc shape, and a plunger cylinder is in a loading and unloading type, and the rotors are installed on a water distributing shaft. An eccentric distance is arranged between the stators and the rotors. When the rotors are rotated, each plunger piston on the rotors sucks and discharges water once. The radial plunger high-pressure water pump has simple structure, light weight and convenient assembly and disassembly, and is suitable for mines to use.
Description
The utility model is the matching used radial plunger high-pressure water pumps of hydraulic equipment such as a kind of and hydraulic drill, hydrofracture pick.
Hydraulic equipments such as hydraulic drill, hydrofracture pick are the new patented technologies of just inventing recently, and it needs, and high-pressure water pump is supporting with it could to be used, and have high-pressure water pump complex structure, very heavy often now, are not suitable for use supporting with it.Therefore be badly in need of designing a kind of high-pressure water pump simple in structure, lightweight, new patented technology such as hydraulic drill, hydrofracture pick is played a role, be converted into productivity.
The purpose of this utility model provides a kind of radial plunger high-pressure water pump of simple in structure, in light weight, reliable operation.
The utility model is achieved in that radial plunger high-pressure water pump is made of the pump housing, stator, pump cover, rotor, water distribution axle, plunger and plunger case, it adopts single-row radial ball bearing as stator, be contained in the pump housing, rotor radial is provided with 5 or 5 with upper plug, plunger head is curved, plunger case is an assembling ﹠ disassembling, and the rotor that has internal spline is assemblied on the water distribution axle, and rotor inner hole and plunger case endoporus are equipped with seal ring.Have an eccentric distance e between stator and the rotor, thereby constitute radial plunger high-pressure water pump.
This high-pressure water pump greatly simplifies the water pump overall structure owing to adopt the single-row radial ball bearing of major diameter, and the outer ring of this bearing is fixed by the pump housing and pump cover, and inner ring can rotate freely.Owing to seal ring is housed at rotor shaft hatch and plunger hole, can effectively reduce the radial and axial internal leakage of pump, the volumetric efficiency of water pump is reached about 0.9.That this pump has is simple in structure, reliable operation, lightweight characteristics.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is the structural drawing of radial plunger high-pressure water pump
Fig. 2 is the sectional view of radial plunger high-pressure water pump
With reference to Fig. 1, the working principle that this water pump is used radial plunger oil pump designs, it is made of the pump housing 1, stator 2, pump cover 3, rotor 4, water distribution axle 5, plunger 6 and plunger case 7, adopt single-row radial ball bearing as stator 2, be contained in the pump housing 1, be fixed with the outer ring of pump cover 3 with bearing, the inner ring of bearing can rotate freely.The footpath of rotor 4 upwards is provided with 5 or 5, and plunger 6 tops are curved with upper plug 6, and plunger 6 diameters adopt φ 24m/m-φ 33.5m/m.Plunger case 7 is an assembling ﹠ disassembling, it with rotor 4 to be threaded, be convenient to the replacing of plunger and plunger case, but also plunger case 7 and rotor 4 can be designed to integrative-structure, plunger case 7 can not be dismantled like this, but its performance and assembling ﹠ disassembling structure are just the same.Rotor 4 is assemblied on the water distribution axle 5, can slide over each other, and has internal spline on the rotor 4, be connected with the elasticity male splined shaft on the line shaft, rotor 4 axis holes and plunger hole have sealing ditch mortise, can place seal ring 8, the radial and axial internal leakage of pump can be effectively reduced, the efficient of pump can be improved.Have suction window a and draining window b on the water distribution axle 5, the width c of a and b adopts 10m/m-18m/m, can form 25 liters/minute, 50 liters/minute, 65 liters/minute three kinds of flows, and pressure is 9-15MPa.Parts such as plunger case, plunger, rotor, water distribution axle can adopt chemical plating nickel-phosphorus alloy or electroplate process treating such as wear-resisting chromium, make it can anti-corrosion, again can be wear-resistant.Has an eccentric distance e between stator 2 and the rotor 4, water distribution axle 5 is fixed, when rotor 4 during by the coupling driven rotary, plunger 6 is under centrifugal action, protruding, press closer the inner ring of stator 2, the Seal cage volume that is in each plunger 6 bottom in the upper half increases gradually, so absorb water into by the window a on the water distribution axle 5, the Seal cage volume that is in each plunger base in the lower half reduces gradually, and by the window b on the water distribution axle 5, draining is gone out, rotor 4 whenever circles, each plunger 6 each suction, draining once has two axial water holes on the water distribution axle 5, with the suction of a and b and water pump, drain opening is connected, rotor 4 constantly rotates, and promptly finishes the suction and the drain function of pump continuously.This pump does not make any changes, and can be used as the radial plunger high pressure oil pump.
