Description
Technical field
The present invention relates to a kind of rotary nozzle speed setting unit, rely on this device can realize carrying out experimental study to the sprinkling uniformity of reaction rotating sprinkler under different rotating speeds condition.
Background technology
Shower nozzle is the key equipment realizing sprinkling irrigation, and reducing one of approach of spray irrigation system energy consumption is exactly reduce operating pressure at sprinkler.Along with the reduction of operating pressure at sprinkler, often cause Sprinkler Performances to reduce, cause irrigation system quality of sprinkler irrigation to reduce.Rotating speed is the important factor in order of Sprinkler Performances.Under uniform pressure flow condition, during shower nozzle rotating speed height, range is short, the water yield is many nearby, and far firing range when rotating speed is low, the water yield is many at a distance.But rotating speed is to the determination relation of shower nozzle irrigation uniformity, and there is not been reported, and do not determine that optimized rotating speed is to ensure that shower nozzle irrigates uniformity, therefore, carries out research to the relation between rotating speed and sprinkler uniformity and seems very necessary.
The present invention proposes a kind of speed setting unit of shower nozzle, and by regulating the size of the moment of resistance, the rotating speed realizing shower nozzle quantizes to regulate, and is conducive to furtheing investigate the impact of rotating speed on sprinkler pattern range and uniformity.
Summary of the invention
The object of the invention is for a kind of structure of sprinkler design is simple, reliable, the speed setting unit of working stability, the quantification that can realize shower nozzle rotating speed regulates, and is conducive to furtheing investigate the impact of rotating speed on reaction rotating sprinkler range and uniformity.
The technical solution used in the present invention is: a kind of rotary nozzle speed setting unit, comprise spray dish, central shaft and head cartridge, rotating driving device and damping adjustment device, described rotating driving device comprises location-plate and damping axle sleeve, described damping axle sleeve fixed cover is on described central shaft, described central shaft one end is fixedly mounted on spray dish top, and the other end is connected with described location-plate revolute pair, described damping adjustment device comprises housing pin, support sleeve, beam barrel, adjusting screw(rod), spring and damping block, described housing pin is through described location-plate, described housing pin terminal surface and described support sleeve upper-end contact, described support sleeve lower end is threaded connection and is fixed on described head cartridge, described beam barrel is through described support sleeve, adjusting screw(rod) is provided with successively in described beam barrel, spring and damping block, described adjusting screw(rod) is threaded with beam barrel, one end of described damping block is stretched out described beam barrel and is contacted with described damping boss face, described spring is between adjusting screw(rod) and damping block.
In such scheme, the diameter that described damping block is positioned at beam barrel internal end surface is greater than the diameter that described damping block stretches out the outside end face of described beam barrel, prevents spring, damping block comes off from beam barrel.
In such scheme, described damping block and described be curved with the contact end face of damping axle sleeve, the radius of described curved is more than or equal to the radius of described damping axle sleeve.
Further, described damping axle sleeve is enclosed within described central shaft by interference fit.
Further, described central shaft one end is arranged on the center on spray dish top by interference fit.
The invention has the advantages that: structure is simple, reliable, working stability, the quantification that can realize different operating pressure lower nozzle rotating speed regulates, and carries out the experimental study of shower nozzle rotating speed to shower nozzle service behaviour.

Detailed description of the invention
Below in conjunction with accompanying drawing, technical scheme of the present invention is described in detail.
As shown in Figure 1, speed setting unit of the present invention is made up of rotating driving device and damping adjustment device.Rotating driving device comprises location-plate 1, central shaft 2, damping axle sleeve 3, spray dish 4, head cartridge 5, support sleeve 6, central shaft 2 is arranged on by interference fit the center that 4 tops are coiled in spray, damping axle sleeve 3 is enclosed within central shaft 2 by interference fit, rotating driving device is fixed on location-plate 1 one end, location-plate 1 other end is fixed on support sleeve 6 by housing pin 11, and support sleeve 6 is threaded connection and is fixed on head cartridge 5.
Damping adjustment device comprises damping adjustment device and comprises beam barrel 7, adjusting screw(rod) 8, spring 9, damping block 10 and housing pin 11, beam barrel 7 is through the axle sleeve on support sleeve 6, and be fixed on support sleeve by housing pin 11, damping block 10 is installed in beam barrel 7 without the end of thread, spring 9 is set in the hole of beam barrel 7, between adjusting screw(rod) 8 and damping block 10, adjusting screw(rod) 8 uses to be threaded and is contained in beam barrel 7.
As shown in Figure 2, damping block 10 is greater than the diameter of damping block 10 in beam barrel 7 inside end at the outlet diameter of beam barrel 7 outer end, so just can prevent spring 9, damping block 10 comes off from beam barrel 7, damping block 10 is curved end surface with the contact end face of damping axle sleeve 3, the radius of end face is more than or equal to the radius of damping axle sleeve 3, and damping block 10 can ensure the strong enforcement of pressure on damping block 10 pairs of damping axle sleeves 3 with this way of contact of damping axle sleeve 3.
The process utilizing device of the present invention to carry out rotational speed regulation is: spray dish 4 has a curved channel, when pressure water flows through curved channel, by the interaction with curved channel, produce driving moment and promote shower nozzle rotation, the frictional resistance moment produced by the pressure of damping block 10 pairs of damping axle sleeves 3 controls the rotating speed of shower nozzle, by changing the degree of tightness of adjusting screw(rod) 8, carrys out the pressure of damping adjusting block 10 pairs of damping axle sleeves 3, thus regulate the size of frictional resistance moment, realize the adjustment of shower nozzle rotating speed.
The elastic modelling quantity had in its regime of elastic deformation due to spring 9 is fixing, spring 9 under the compression of adjusting screw(rod) 8 to the pressure consecutive variations of damping block 10, thus produce frictional resistance moment also consecutive variations.During shower nozzle work, under certain operating pressure, the driving moment of shower nozzle is constant, and often rotate adjusting screw(rod) 8 one and enclose, the change of frictional resistance moment is fixing, by fine setting adjusting screw(rod) 8, can reach certain fixed rotating speed meeting test requirements document.
