Abstract
The utility model relates to a rotary vane pump type cleaning machine capable of spraying water, which comprises a pump, a driving device, an automatic switching valve and a water spraying gun and is characterized in that the pump is a rotary vane pump. The utility model has the advantages of simple structure, easy fabrication, low cost, stable running, small vibration, low noise, high pressure adsorbing efficiency and low energy consumption. The utility model can be widely used in the field of the water cleanness of automobiles and other devices, with convenient usage and operation and favorable cleaning effect.
Description
The utility model relates to a kind of sliding vane rotary pump formula cleaning machine, and it has simple in structure, the characteristics that operate steadily.
Cleaning machine is made of pump, automatic transfer valve and three main portions of water pistol, and it is to spray the purpose that object reaches cleaning by producing penstock.At present, this water jet cleaning machine has been widely used in the cleaning field of miscellaneous equipments such as automobile.But existing cleaning machine mostly adopts the reciprocating pump of piston crank mechanism as its pressure source, and it is comparatively complicated that this pump is not only constructed, and it is difficult to make, the price height, and also vibration is big during operation, the energy consumption height, and noise pollution is serious.
The purpose of this utility model is to provide a kind of simple in structure, the sliding vane rotary pump formula cleaning machine that operates steadily at the deficiency of above-mentioned existence.
The technical scheme that realizes the utility model purpose is: include pump, actuating device, automatic transfer valve and water pistol, its difference is that described pump is a sliding vane rotary pump.
Advantage of the present utility model is: 1, adopt sliding vane rotary pump, and simple in structure, to make easily, cost is low; 2, sliding vane rotary pump does not have reciprocator, operates steadily, and vibrates for a short time, inhale to press the efficient height, and energy consumption is low.
Fig. 1 is the constructional drawing of facing of an embodiment of the utility model.
Fig. 2 is the side-looking constructional drawing of an embodiment of the utility model.
Fig. 3 is the enlarged drawing of automatic transfer valve among Fig. 1.
Further specify embodiment of the present utility model below in conjunction with accompanying drawing, include a sliding vane rotary pump, sliding vane rotary pump is by the pump housing 17, the rotor 19 that off-centre is installed in the pump housing constitutes with the blade 16 that is loaded in the rotor, be provided with blade spring 28 in the blade, the two ends of the pump housing are by a left side, right end cap 36,34 seal, be supported with pump shaft 33 by bearing 31 and spacer 32 in the pump housing, one end and the rotor 19 of pump shaft connect firmly, and by seal ring 29 and oil sealing 30 sealings, the other end and actuating device join, actuating device is by big belt pulley 20, driving band 25 is formed with small belt pulley 22 and motor 21 that motor links, water outlet at sliding vane rotary pump joins by a check valve 4 and an automatic transfer valve, the structure of automatic transfer valve as shown in Figure 3, include a valve body 14, valve body is provided with water inlet, water outlet and water return outlet, water inlet is positioned at the bottom of valve body, from water inlet to valve pocket be installed on piston 6 and with the damper valve plate 7 and the damping spring 8 of its configuration, suit tubulose spool 9 among them, tubulose spool upper end communicates with water return outlet, and with the inner cone valve 13 that is installed in valve body upper end, diversion valve rod 11 phase configuration, the inner cone valve is set in the valve seat 39 and regulates its pressure by pressure spring 12 and pressure regulation handwheel 10, tubulose spool 9 can move up and down under the effect of piston 6, make water return outlet and water inlet conducting or close, its upper periphery is equipped with seal ring 38 and seal strip 37, the groundwork mechanism of this automatic transfer valve is: when water pistol is opened water spray, because pressure differential effect, make on the piston and move, promote to move on tubulose spool and the damper valve plate 7, moving the back on the tubulose spool joins with the inner cone valve, water return outlet is closed withstand piston simultaneously, this moment, current were by moving on the apopore pressure drag Buddhist nun valve block of opening on the piston, the damper valve plate of closing is opened, even water inlet and water outlet conducting; When water pistol turn-offed, because pressure differential disappears, the tubulose spool was descending with piston under the effect of damping spring, damper valve plate also return is closed, water outlet is closed and the water return outlet conducting, circulate thus, can under the state that does not turn-off pump, finish the task of automatic switchover like this.On automatic transfer valve, can pacify and not have water pressure gauge 35, the water outlet of automatic transfer valve is connected with water pistol 1 by coolant outlet pipe 3, the water return outlet of automatic transfer valve joins through return water pipe 15 and threeway water supply connector 18, one end of threeway water supply connector is connected with the water inlet of sliding vane rotary pump, the other end is connected through coolant inlet pipe 23 and suction filter screen 24, sliding vane rotary pump and actuating device all are mounted on the frame 26, for ease of moving, the frame below is installed on roller 27, one side top is installed on handrail 5, is equipped with leg 2 under the frame of handrail below.
