Abstract
The utility model relates to a gear bearing type high pressure pump with the capability of self pressure regulation. A bearing is arranged in a pump body, and a gear shaft sleeve is arranged in the bearing. In addition, a pressure regulating valve of the utility model is formed in a way that a communicating pipe is arranged in a valve body, a needle valve is arranged at the pipe opening point, a spring is arranged behind the needle valve, the back of the spring is pressed against by a screw rod and a pressure regulating handle is arranged on the screw rod. A water discharge opening which is arranged on the valve body of the regulating valve is connected with the pump body through a pipeline. A screw buckle is arranged on the valve body of the regulating valve, and the screw buckle can be arranged on a pressure chamber and communicated with the pressure chamber together. Due to the adoption of the bearing as a shaft sleeve, the utility model has the advantages of smooth operation, the little possibility of damage and the improvement of work efficiency. The pipe opening of the communicating pipe is sealed under normal work pressure. When the pressure is too large, the needle valve is pushed open, and liquid in a pressure pump flows back to the pump body through the water discharge opening from the communicating pipe, which is convenient for reducing pressure. When pressure is reduced to required pressure, the pipe opening of the communicating pipe is blocked again by the needle valve under the action of the spring, which plays the function of automatic pressure regulation.
Description
Technical field
The utility model relates to a kind of gear type high-pressure service pump that is used for spray liquid, clear water or coating.
Background technique
Presently used gear type high-pressure service pump all is to be power with the diesel engine, drive belt pulley, belt pulley drives crankshaft rotating, bent axle is provided with driving gear, and driving gear drives the driven gear rotation, forms vacuum under the high speed rotating of driving gear and driven gear, make liquid enter the working room, and by gear transmission liquid is pressed into pressurized tank, reach certain pressure after, by liquid outlet the atomization of liquid is sprayed.The housing of these gear type high-pressure service pumps, driving gear and driven gear are fully cylinder iron cast, and axle and gear are splits, and gear is fixed on the axle with pin, and axle sleeve is contained in the interior copper sheathing of casing.The high-pressure service pump of this structure, because axle is installed in the copper sheathing, axle rotates in copper sheathing, the phase mutual friction, under the high speed rotating, axle is severe fragile with the copper sheathing wearing and tearing, and running is obstructed, and working efficiency reduces.In addition, for preventing overhigh pumping pressure, pressure regulator valve all is installed in the pressure chamber, and these pressure regulator valves all are manual, the discharging valve of similar radiator, promptly be installed in the pressure chamber with pin type plug discharging valve, the dewatering outlet of pin type plug discharging valve is connected with the pump housing by pipeline, and pressure is big, with hand adjustment pine needle formula plug, the liquid of pressure chamber is emitted, flow back to the pump housing by pipeline.In work time, need to adjust at any time, and careless slightly, pump housing overpressure collapses out the connecting tube on the pump housing, promptly causes damage and influence work.
Summary of the invention
It is little that the purpose of this utility model provides between a kind of axle and the copper sheathing wearing and tearing, high working efficiency, and can automatic Regulation from pressure regulation gear-bearing formula high-pressure service pump.The purpose of this utility model is achieved in that the utility model is made of gear shaft, nut, belt pulley, key, gear, pressure chamber, pump cover, O RunddichtringO, plug, pump seat, inlet valve, water outlet, water outlet threeway, pressure gauge, backwater mouth, shower nozzle, pressure regulator valve, surge pipe pipe and the pump housing.Bearing is set in the pump housing, and gear bush is contained in the bearing.Pressure regulator valve is that a connecting pipe is set in valve body, mouth of pipe place establishes a needle-valve, establishes a spring behind the needle-valve, has leading screw to head on behind the spring, needle-valve is sealed the mouth of pipe of connecting tube under the effect of spring pressure, can be used for metering pin valve pressure size by being located at pressure regulation handle on the leading screw.In addition, the valve body of modulating valve is provided with the dewatering outlet and is connected with the pump housing by pipeline.Have screw thread on the valve body of modulating valve, be installed in the pressure chamber, and be connected together with the pressure chamber.The utility model is owing to adopt bearing to make axle sleeve, and running is smooth, and is not fragile, and working efficiency improves.In addition, when the pressure of pressure chamber was excessive, needle-valve was backed down, and liquid flows back to the pump housing by being communicated with the mouth of pipe through the dewatering outlet, is convenient to decompression, reduces pressure to when requiring pressure, and needle-valve is blocked the mouth of pipe of connecting tube again under the effect of spring, plays the effect of automatic Regulation.
