Abstract
The utility model relates to a self-suction vortex pump without a one-way valve. The utility model is characterized in that the volume of a suction chamber of a pump body is greater than the volume of an air-water separation chamber, and the position of a water inlet is higher than the position of a water outlet. The improved self-suction vortex pump has the advantages that when the pump body is stopped, the water can not pass through the water inlet to flow back in a suction pipe for ensuring that the suction chamber has water storage capacity with sufficient water level to supply the pump body to faster complete the separation of the air and the water when the pump body is started, and the action of self-suction can be carried out. Compared with the prior art, the utility model has the advantages of reasonable structure, easy fabrication, low cost, reliable self-suction function, convenient use, etc.
Description
The utility model belongs to picotan, particularly a kind of self priming vortex pump that need not one-way valve.
The self priming vortex pump volume is little, the lift height, and self-absorption function is good, is civilian and industrial water lift apparatus commonly used.Suction chamber volume in the common self priming vortex pump chamber is less than air-water separation chamber; water in order to prevent to shut down in the chamber produces from the siphonage that air-water separation chamber is back to suction chamber; water intake at the suction chamber of pump chamber disposes an one-way valve, makes that water can aspirate when starting shooting once more.But, because one-way valve is to utilize rubber to be fixed on the valve seat of water intake, very easily aging, add factors such as being subjected to one-way valve processing precise degree and seat design and all can influence the pump self-absorption function, so in actual use, always need before the start in pump chamber, to pour water earlier, in the time of could guaranteeing start, suction rapidly, this brings not convenient greatly undoubtedly to the user.
The utility model purpose is to provide a kind of self priming vortex pump that need not to be provided with one-way valve, and it can overcome in the prior art could realize the shortcoming of suction action by pouring water, thereby uses more convenient.
According to the purpose that the utility model provides, inventor's solution is: 1, the suction chamber volume is enlarged, make it greater than air-water separation chamber; 2, the water inlet position of suction chamber is designed to such an extent that exceed the water outlet position; because above two measures add the cut water function that upper pump casing is provided with; just can stop and produce siphonage when shutting down; thereby guaranteed to shut down the water yield of the certain high water level of contain in the pump housing of back, when starting shooting once more, can finish air-water separation quickly and reach the self-priming effect.Compared with prior art, the utlity model has following advantage: 1, reasonable in design, simple in structure, the only volume of two inner cavity chamber of need change, and corresponding raising water intake position gets final product, and all the other structures need not change; 2, cancellation chamber internal check valve had both been simplified production technology, had reduced the product cost again; Need not to pour water in advance when 3, starting shooting, self-absorption function is reliable, the efficient height, and it is very convenient to use.
Further describe the utility model below in conjunction with drawings and Examples.
Fig. 1 is the utility model structural representation
Fig. 2 is the another structural representation intention of the utility model
Embodiment 1 as shown in Figure 1, the utility model pump body structure comprises suction chamber 1, air-water separation chamber 2, water intake 3, water outlet 4, cut water 5, plate washer 6, axis hole 7, fixed hole 8 formations such as grade.The utility model feature be the volume of suction chamber 1 greater than air-water separation chamber 2, water intake 3 positions are higher than the position of water outlet 4.The self priming vortex pump good effect that need not one-way pump that the utility model constitutes is when the pump housing is shut down; can stop the generation of siphonage in the pump housing effectively; be unlikely water is back in the suction sleeve through water intake 3 more; thereby guaranteed to have in the suction chamber 1 of the pump housing water storage capacity of enough water levels; comparatively fast finish the air-water separation purpose during start of the supply pump housing, carry out the self-priming action.
Difference only is the evolution of pump housing water intake 3 between embodiment 2 and the embodiment 1, can design diverse location at the pump housing with the position of explanation water intake 3.
