Abstract
The utility model relates to a reversible centrifugal pump, comprising a pump body (1), an impeller (2), a pump cover (3), a shaft (6), etc. The reversible centrifugal pump is characterized in that two rows of blades are arranged on the impeller (2), and the blades are twisted in parallel in normal and inverse directions; two ports (12, 13) of the pump body (1) are arranged on the same shaft line; two ports can be used as liquid outlets as well as liquid inlets; the water pressing chambers of the pump body (1) are double water pressing chambers with double flow passages. The reversible centrifugal pump can be used for alternate suction and discharge, the reversible centrifugal pump can be used for two purposes, technological equipment are reduced, labor intensity is relieved, operating programs are simplified, and work efficiency is increased. The reversible centrifugal pump is suitable for operational places needing alternate suction and discharge such as petroleum, chemical engineering, sewage disposal, farmland drainage and irrigation.
Description
The utility model relates to a kind of liquid pump, particularly a kind of reversible centrifugal pump.
At present used centrifugal pump is made up of parts such as the pump housing, impeller, pump cover and axles, has only a blade of arranging by consistent direction arrangement on the impeller, so, the deficiency of this centrifugal pump is that the liquid inhaled can not adverse current, uses inconvenience in some place.
The purpose of this utility model is exactly the deficiency at existing centrifugal pump, and a kind of reversible centrifugal pump is provided, and the liquid of being inhaled can reversely be flowed, and energy one pump is dual-purpose.
The utility model is achieved in that this pump comprises the pump housing (1), impeller (2), pump cover (3) and axle parts such as (6), the pumping chamber of its pump housing (1) is the two pumping chambers of double flow channel, liquid entering hole both can be done in pump housing port (12) and (13) of the pump housing (1), also can do liquid outlet, two ports (12) of the pump housing (1), (13) are formulated on the same axis, blade on the impeller (2) is two rows, and the arrangement mode of two row's blades is one positive one parallel anti-two direction twisted array.
Below in conjunction with accompanying drawing the utility model is done detailed description.
Fig. 1 is a structural representation of the present utility model
1 is the pump housing among the figure, and 2 is impeller, and 3 is pump cover, and 4 is mechanical sealing base, and 5 is mechanical seal ring, and 6 is axle, and 7 is bolt, and 8 is motor, and 9 is seal ring, and 10 is impeller nut (1), and 11 is key, and 12 is pump housing port, and 13 is pump housing port.
Assembling mode of the present utility model is, axle (6) being passed the center hole of pump cover (3) puts in the pump housing (1), be installed on the axle (6) having the be arranged in parallel impeller (2) of blade of two rows, one positive one anti-both direction, and fixing with key (11) and impeller nut (10), prevent that impeller (2) from moving.Seal ring (9) is installed on the pump housing wall at the interior pump housing of the pump housing (1) and place, impeller joining portion, mechanical sealing base (4) and mechanical seal ring (5) are installed in pump cover (3) center hole, can prevent leak of liquid in the pump housing, pump cover (3) is installed on the pump housing (1), then becomes by bolt (7) is fixing.
The utility model has the advantages that, but this pump suction hocket, can a pump dual-purpose, reduce process equipment, reduce labor intensity, simplify procedures, increase work efficiency. Use is extensive, is suitable for oil, chemical industry, You Chang, oil depot, sewage disposal, sewage purification, and the loading and unloading of car are filled with in transportation, and use in the operation place that farmland discharging-irrigating etc. need suction to hocket.
