Abstract
A pumping unit washing device comprises a motor, a plunger pump and an energy storing device. A power shaft of the motor is connected with a power shaft of the plunger pump. The energy storing device comprises a shell, a baffle ring, a piston and a spring, wherein the shell is of a cylindrical structure, the baffle ring is arranged at the 1/3-1/5 position far away form one end of an inner cavity of the shell, the piston is arranged on the right side of the baffle ring, the spring is installed between the piston and the right end of the inner cavity of the shell, a pressure control switch is installed on the shell on the left side of the baffle ring, and a safety valve is arranged on the left end portion of the shell. A high-pressure pipe of the plunger pump is connected with the left end portion of the energy storing device and an output pipe in a communicated mode. A power source is electrically connected with the motor through the pressure control switch. The structure that the energy storing device is combined with the plunger pump is adopted, so that compared with the prior art, the pumping unit washing device has the advantages of being simple in structure, convenient and safe to use, saving in energy and durable.
Description
Technical field
The utility model relates to a kind of high-pressure cleaning device, is specifically related to a kind of pumping unit washing unit.
Background technique
Cleaning for pumping unit; the plunger jetting machines that adopt more; but existing plunger jetting machine is simple in structure; but there is no energy storage device, easily cause high voltage terminal pressure transient and interior pressure to rise suddenly and accelerate pump housing damage, mostly there is no the pressure limiting stopping function; not only waste energy but also accelerate the aging of pump housing inner sealing and mechanical part and damage; and be provided with pressure limiting outage stopping function owing to can not energy storage causing the frequent stop and start of motor, motor and the pump housing are impacted, affected working life.
The model utility content
The purpose of this utility model is exactly the defect existed for prior art, and a kind of pumping unit washing unit is provided.
Its technological scheme is: the pumping unit washing unit, comprise motor, plunger pump and energy storage device, and the line shaft of motor is connected with the line shaft of plunger 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 1/3-1/5 place, the baffle ring right side is provided with piston, between piston and 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 safety valve; The high-voltage tube of described plunger pump connects and is connected with energy storage device left part and output tube; Power supply is electrically connected to 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 plunger pump is provided with low-voltage tube.
The structure that the utility model has adopted energy storage device to combine with plunger pump, make it compared with prior art, has advantages of safety simple in structure, easy to use, energy-saving durable.
The accompanying drawing explanation
Fig. 1 is a kind of embodiment's of the utility model structural representation.
Embodiment
With reference to Fig. 1, a kind of pumping unit washing unit, comprise motor 1, plunger pump 2 and energy storage device, and the line shaft of motor 1 is connected with the line shaft of plunger 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 chamber one end 1/3-1/5 places, baffle ring 8 right sides are provided with piston 9, between piston 9 and 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 safety valve 12; The high-voltage tube 6 of described plunger pump 2 connects and is connected with energy storage device left part and relief tube 7; Power supply 11 is electrically connected to motor 1 by pressure control switch 3.Described energy storage device is set at least one.The top of plunger 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 washing machine outside; high-voltage tube 6 and the relief tube 7 of plunger pump 2 are connected with the compressible end of energy storage device; by the pressure upper and lower is set; the pressure pumped during work is cushioned by piston spring; during the temporary close of pressure release part; piston continues compressed; the accumulation chamber volume increases. and after reaching the upper limits pressure of setting, pressure control switch 3 cuts off the electricity supply, and has played protection and energy-conserving action.Safety valve 12 designs for preventing the unexpected superpressure of energy storage device.
After relief tube 7 is opened, because accumulation chamber pressure decreased spring promotes the piston accumulation chamber volume that moves ahead, reduce to have kept pressure, pressure control switch 3 switches on power simultaneously, and the motor Low loading start up, played protection and energy-conserving action equally.
