摘要：【中文】本发明涉及一种喷雾机风筒。喷雾机风筒，包括自左向右依次连接的前筒、中筒、后筒，所述中筒由中外筒和中内筒构成，中内筒内部设置电机，中外筒一端的内表面上有外挡止结构，中内筒一端的外表面设有与外挡止结构形成挡止配合的内挡止结构，中外筒另一端的内侧面上有与中内筒可拆固定连接的连接结构，中内筒的内挡止结构与中外筒的筒壁之间形成能够径向相对移动的环形配合间隙。当电机在运行过程中发生振动时，由于电机固定在中内筒内部，中内筒的一端与中外筒之间存在环形配合间隙，会减弱传递给中外筒的振动，减小了中外筒的振动，避免因中外筒振动产生的螺栓松动和焊口脱焊，保证了喷雾机的持续运行，提高了喷雾机的工作效率。 【EN】The invention relates to a wind barrel of a spraying machine. The sprayer air duct comprises a front duct, a middle duct and a rear duct which are sequentially connected from left to right, wherein the middle duct is composed of a middle outer duct and a middle inner duct, a motor is arranged in the middle inner duct, an outer blocking structure is arranged on the inner surface of one end of the middle outer duct, an inner blocking structure which forms blocking fit with the outer blocking structure is arranged on the outer surface of one end of the middle inner duct, a connecting structure which is detachably and fixedly connected with the middle inner duct is arranged on the inner side surface of the other end of the middle outer duct, and an annular fit clearance which can move relatively in the radial direction is formed between the inner blocking structure of the middle inner duct and the wall of the middle outer duct. When the motor vibrates in the operation process, because the motor is fixed in the middle inner cylinder, and an annular fit clearance exists between one end of the middle inner cylinder and the middle outer cylinder, the vibration transmitted to the middle outer cylinder can be weakened, the vibration of the middle outer cylinder and the middle outer cylinder is reduced, the bolt looseness and weld crater desoldering caused by the vibration of the middle outer cylinder are avoided, the continuous operation of the sprayer is ensured, and the working efficiency of the sprayer is improved.

摘要：【中文】本发明涉及一种清洗车及其水路控制装置，属于采用喷射力进行清洁的技术领域，水路控制装置包括依次连接的水压设定装置、信息处理单元、电机控制器，以及连接信息处理单元的压力传感器，水压设定装置用于设定清洗车中柱塞泵出水的水压，压力传感器用于检测清洗车中柱塞泵实际出水的水压，信息处理单元用于实时比较柱塞泵出水的水压实际值与设定值的偏差，电机控制器用于根据偏差实时调节柱塞泵的电机转速，使柱塞泵出水的水压实际值与设定值的偏差逐渐减小，直至水压实际值与设定值相等，避免了路况较差的路段清洗效果不佳以及路况较好的路段水压值又相对较大，造成的压力和水力资源的浪费问题，实现了所给即所需的最大经济效益。 【EN】The invention relates to a cleaning vehicle and a waterway control device thereof, belonging to the technical field of cleaning by adopting injection force, the waterway control device comprises a water pressure setting device, an information processing unit, a motor controller and a pressure sensor connected with the information processing unit, the water pressure setting device is used for setting the water pressure of plunger pump water in the cleaning vehicle, the pressure sensor is used for detecting the water pressure of plunger pump water in the cleaning vehicle, the information processing unit is used for comparing the deviation of the actual water pressure value of the plunger pump water and a set value in real time, the motor controller is used for adjusting the motor rotating speed of the plunger pump in real time according to the deviation, so that the deviation of the actual water pressure value of the plunger pump water and the set value is gradually reduced until the actual water pressure value is equal to the set value, thereby avoiding poor cleaning effect of road sections with poor road conditions and relatively large water pressure value of road sections with good road conditions, the waste of pressure and hydraulic resources is caused, and the maximum economic benefit required immediately is realized.

摘要：【中文】本发明涉及一种风机叶轮的轮盘和叶片连接定位工装，风机叶轮的轮盘和叶片连接定位工装包括定位平台，定位平台上转动装配有转轴，定义转轴的轴向为上下方向，转轴上设有用于定位轮盘以使轮盘与转轴同轴转动的轮盘定位部，所述定位平台上还设有用于定位夹紧叶片的叶片定位部，所述转轴上还设有与转轴止转配合的分度盘，分度盘上绕其周向间隔布置有若干个分别用于与轮盘上相应叶片的连接位置对应的定位部，定位平台上还活动设有与定位部插装配合而与分度盘沿分度盘的周向挡止配合以将轮盘定位的限位件。定位效果比较好，而且定位精度较高，进一步保证叶片与轮盘连接时定位的一致性。 【EN】The invention relates to a wheel disc and blade connecting and positioning tool of a fan impeller, which comprises a positioning platform, wherein a rotating shaft is rotatably assembled on the positioning platform, the axial direction of the rotating shaft is defined as the vertical direction, a wheel disc positioning part used for positioning the wheel disc to enable the wheel disc and the rotating shaft to coaxially rotate is arranged on the rotating shaft, a blade positioning part used for positioning and clamping a blade is also arranged on the positioning platform, a dividing disc matched with the rotating shaft in a rotation stopping way is also arranged on the rotating shaft, a plurality of positioning parts respectively corresponding to the connecting positions of the corresponding blades on the wheel disc are arranged on the dividing disc at intervals in the circumferential direction of the dividing disc, and a limiting part which is inserted and matched with the positioning parts in a plugging way and matched with the dividing disc in a blocking way along the circumferential direction of the dividing disc.
