Abstract
An energy storage protection high pressure washer comprises a motor, a hydraulic plunger pump and an energy storage device, wherein a power shaft of the motor is connected with a power shaft of the hydraulic plunger pump. The energy storage device comprises a casing of a cylindrical structure, a check ring, a piston and a spring. The check ring is arranged at the position away from one end of an inner cavity of the casing for 1/6-1/7, the piston is arranged on the right side of the check ring, the spring is arranged between the piston and the right end of the inner cavity of the casing, a pressure control switch is arranged on the casing located on the left side of the check ring, and a safety valve is arranged at the left end of the casing. A high pressure pipe of the hydraulic plunger pump, the left end of the energy storage device and an output pipe are connected in a communicated mode. A power supply is electrically connected with the motor through the pressure control switch. The energy storage device is combined with the hydraulic plunger pump so that compared with the prior art, the energy storage protection high pressure washer has the advantages of being simple in structure, safe and convenient to use, energy saving and durable.
Description
Technical field
The utility model relates to a kind of jetting machine, is specifically related to a kind of energy storage protection jetting machine.
Background technology
Existing plunger jetting machine is simple in structure; but there is not energy storage device; easily cause high-pressure side pressure transient and interior pressure to rise suddenly and accelerate pump housing damage; there is not pressure limiting to shut down function mostly; not only waste energy but also accelerate the aging and damage of pump housing inner sealing and mechanical part; and be provided with pressure limiting outage shut down function owing to can not energy storage cause the frequent stop and start of motor, motor and the pump housing are impacted, influenced service life.
The utility model content
The purpose of this utility model is exactly the defective that exists at prior art, and a kind of energy storage protection jetting machine is provided.
Its technical scheme is: comprise motor, hydraulic planger pump and energy storage device, the line shaft of motor is connected with the line shaft of hydraulic planger pump.Energy storage device comprises housing, baffle ring, piston and the spring of cylinder-like structure, described baffle ring is arranged on apart from housing inner chamber one end 1/6-1/7 place, the baffle ring right side is provided with piston, between piston and the housing inner chamber right-hand member spring is installed, on the housing in baffle ring left side pressure control switch is installed, the housing left part is provided with the spring Low lift safety valve; The high-voltage tube of described hydraulic planger pump connects with energy storage device left part and efferent duct and is connected; Power supply is electrically connected with motor by pressure control switch.
Described energy storage device is set at least one.Described energy storage device is set at least one.The top of hydraulic planger pump is provided with low-voltage tube.
The utility model has adopted energy storage device and hydraulic planger pump structure combining, makes it compared with prior art, has the advantage of safety simple in structure, easy to use, energy-saving durable.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
The specific embodiment
With reference to Fig. 1, a kind of energy storage protection jetting machine comprises motor 1, hydraulic planger pump 2 and energy storage device, and the line shaft of motor 1 is connected with the line shaft of hydraulic planger pump 2.Energy storage device comprises housing 4, baffle ring 8, piston 9 and the spring 10 of cylinder-like structure, described baffle ring 8 is arranged on apart from housing 4 inner chambers one end 1/6-1/7 place, baffle ring 8 right sides are provided with piston 9, between piston 9 and the housing 4 inner chamber right-hand members spring 10 is installed, on the housing 4 in baffle ring 8 left sides pressure control switch 3 is installed, housing 4 left parts are provided with spring Low lift safety valve 12; The high-voltage tube 6 of described hydraulic planger pump 2 connects with energy storage device left part and relief tube 7 and is connected; Power supply 11 is electrically connected with motor 1 by pressure control switch 3.Described energy storage device is set at least one.The top of hydraulic planger pump 2 is provided with low-voltage tube 5.
The utility model is to increase one or several variable pressure volume piston spring energy storage device according to pressure and flow in existing high-pressure plunger cleaning machine outside; high-voltage tube 6 and the relief tube 7 of hydraulic planger pump 2 are connected with the compressible end of energy storage device; by the pressure bound is set; the pressure that pumps during work is cushioned by piston spring; during the temporary close of pressure release part; piston continues compressed; the accumulation chamber volume increases. and pressure control switch 3 is namely cut off the electricity supply after reaching the upper limit pressure of setting, has played protection and energy-conserving action.Safety valve 12 designs for preventing the unexpected superpressure of energy storage device.
After relief tube 7 was opened, the accumulation chamber volume reduced to have kept pressure because accumulation chamber pressure reduction spring promotion piston moves ahead, and pressure control switch 3 is connected power supply simultaneously, and the motor underload starts, and has played protection and energy-conserving action equally.
