Abstract
The utility model relates to centrifugal pump pumping equipment, specifically to a centrifugal pump pumping apparatus provided with a seal suction chamber. The centrifugal pump pumping apparatus comprises a pumping pipe, a centrifugal pump, and the seal suction chamber; the upper end of the pumping pipe is inserted into the seal suction chamber from the bottom in a sealed manner; the top of the seal suction chamber is provided with a pump priming opening connected with a seal valve; the lower portion of the seal suction chamber is in tight coupling with the centrifugal pump provided with a pump valve; the upper end of the pumping pipe is higher than an upper edge of a connector between the seal suction chamber and the centrifugal pump; and the upper end opening of the pumping pipe is deviated from the pump priming opening in a horizontal direction. With one-off pump priming in the seal suction chamber, the liquid surface in the seal suction chamber maintains a stable height dynamically during halt and use of the centrifugal pump, so the centrifugal pump pumping apparatus can be used for a long time with one-off pump priming, has simple processes and improved efficiency, requires no check valve, and realizes reliable and stable work.
Description
Technical field
The utility model relates to a kind of centrifugal pump pumping equipment, relates in particular to a kind of centrifugal pump pumping equipment that seals suction chamber that has.
Background technique
Centrifugal pump is the conventional machinery of a kind of lifting, conveying or compressed fluid.Before the centrifugal pump pumping equipment starts, must experience one sending water filled drinking-water pipe, the pump priming process of impeller and pump case; Concrete way is that the upper end of drinking-water pipe connects centrifugal pump, is provided with one-way valve and go deep into the liquid level end; The liquid level epimere of drinking-water pipe connects the pump priming pipe, in drinking-water pipe, injects water by the pump priming pipe, fills drinking-water pipe until water; Impeller and pump case start centrifugal pump, and water just can be pumped up.There is following shortcoming in present centrifugal pump pumping equipment: all will experience the process of a pump priming during owing to each the use, so complex procedures, efficient is low; And when in a single day one-way valve breaks down, just can't normally accomplish the pump priming operation, centrifugal pump just can't use.
The model utility content
The utility model technical problem to be solved is, overcomes the deficiency that exists in the existing technology, provide a kind of disposable pump priming permanent use and reliable and stable work have a centrifugal pump pumping equipment that seals suction chamber.
The utility model is to be achieved through following technological scheme:
A kind of centrifugal pump pumping equipment that seals suction chamber that has; Comprise drinking-water pipe and centrifugal pump, be provided with a sealing suction chamber, insert from the bottom seals of sealing suction chamber the upper end of said drinking-water pipe; Said sealing suction chamber top is provided with the pump priming mouth that connects seal valve; The lower seal of sealing suction chamber connects the centrifugal pump that has pump valve, and the upper end of drinking-water pipe is higher than the connection mouth upper edge of sealing suction chamber and centrifugal pump, and the upper end port and the pump priming mouth of said drinking-water pipe depart from setting in the horizontal direction.
The beneficial effect of the utility model is:
Owing between centrifugal pump and drinking-water pipe, having added the sealing suction chamber, only need to accomplishing a pump priming in the sealing suction chamber, in centrifugal pump shutdown and using process; Liquid level keeps Metacentre Height dynamically in the sealing suction chamber, so just can the centrifugal pump pumping equipment used disposable pump priming for a long time, need not one time one filling; Operation is simple, and efficient improves, and the upper end port of drinking-water pipe and pump priming mouth depart from setting in the horizontal direction; Water flows directly in the sealing suction chamber during pump priming; Then need not the control of one-way valve, saved one-way valve, reliable and stable work.
Description of drawings
Fig. 1 is the main TV structure schematic representation of the utility model.
Among the figure: 1. seal suction chamber, 2. liquid level in the sealing suction chamber, 3. drinking-water pipe, 4. suction liquid level, 5. centrifugal pump, 6. pump valve, 7. seal valve, 8. pump priming mouth.
Embodiment
For the technician who makes the present technique field understands the technological scheme of the utility model better, the utility model is done further to specify below in conjunction with accompanying drawing and most preferred embodiment.
As shown in Figure 1; The utility model comprises drinking-water pipe 3 and centrifugal pump 5, is provided with a sealing suction chamber 1, and insert from the bottom seals of sealing suction chamber the upper end of said drinking-water pipe; Said sealing suction chamber top is provided with the pump priming mouth 8 that connects seal valve 7; The lower seal of sealing suction chamber connects the centrifugal pump 5 that has pump valve 6, and the upper end of drinking-water pipe is higher than the connection mouth upper edge of sealing suction chamber and centrifugal pump, and the upper end port and the pump priming mouth of said drinking-water pipe depart from setting in the horizontal direction.
During work, open seal valve 7 and in sealing suction chamber 1, pour water, make water be higher than the connection mouth upper edge of sealing suction chamber and centrifugal pump, but be lower than the upper end of drinking-water pipe from pump priming mouth 8; So just, accomplished the process of a pump priming, opened pump valve 6, centrifugal pump 5 just can use, when centrifugal pump 5 is extracted water out; Liquid level 2 descends in the sealing suction chamber, and sealing suction chamber internal air pressure diminishes, and water just is evacuated to sealing suction chamber 1 in drinking-water pipe, makes the liquid level 2 dynamic Metacentre Heights that keep in the sealing suction chamber; So just, can the centrifugal pump pumping equipment used disposable pump priming for a long time, need not one time one filling, operation be simple; Efficient improves, and the upper end port of drinking-water pipe departs from the pump priming mouth in the horizontal direction, and water flows directly into and seals in the suction chamber during pump priming; Then need not the control of one-way valve, saved one-way valve, reliable and stable work.
The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
