Abstract

The utility model relates to a high-pressure vortex pump, which is composed of a motor, a pump body, a shaft, an enclosed type impeller, a flow channel, a pump cover, sealing components, etc. The number of blades of single side of the enclosed type impeller is 2.5 to 4 sheets per centimeter circumference of the impeller rim; the ratio of water contact area of every two sheets of blades which are parallel at the left and right sides of the impeller and axial sectional area of the flow channel is 0.45-0.55 to 1. The delivery lift can be obviously enhanced; a plurality of impellers and each corresponding flow channel can be used. Each flow channel are mutually separated; the front end and the back end of each flow channel are mutually in series connection, which can make the utility model obtain bigger delivery lift. Having the advantages of simple structure, short axial dimension, light weight, small size and low cost, the utility model is suitable for water supply in high-rise buildings for residents in urban and rural areas.

Description

The high pressure peripheral pump

The utility model relates to a kind of high pressure peripheral pump.

Peripheral pump is little, simple in structure and be widely used as piston type domestic water pump with its volume, still, because the vortex lift of pump is subjected to the restriction of impeller diameter and rotating speed, so building water supply has proposed considerable problem just for the particularly undersized miniature peripheral pump of peripheral pump.In Chinese patent application, for example application number is the Chinese patent application of 91109556.X, has proposed multiple solution, but these schemes, for the micro pump of family expenses, still exist complex structure, the high deficiency of requirement on machining accuracy, and manufacture cost is higher.

The purpose of this utility model provides a kind of simple in structure, with low cost, high pressure peripheral pump that can satisfy the building water supply requirement.

The utility model is so to realize: the high pressure peripheral pump is made of motor, the pump housing, axle, double shrouded wheel, runner, pump cover and Sealing etc., and a side number of blade of double shrouded wheel is 2.5～4 of every centimetre of girths of wheel rim.The long-pending ratio of strike waters area and runner axial cross section of per two blades that the impeller left and right sides is arranged side by side is 0.45～0.55: 1.

The utility model can also with plurality of impeller and corresponding separately runner, with isolate mutually between runner, the head end and the tail end of each runner be connected in series each other, forms multistage pump, can obtain higher pressure.

Because the utility model has proposed new design proposal to the blade sheet number of peripheral pump impeller and the sectional area of blade area and runner, has improved the pressure of peripheral pump effectively, thereby has satisfied as the economical and practical requirement of domestic miniature water pump.Because the difficulty that this design proposal does not increase the complexity of structure and makes, so the utility model is simple in structure, axial length is short, in light weight, volume is little, cost is low, is specially adapted to directly connect with motor, for the usefulness of urban and rural residents' building water supply.

Now be described further with following embodiment and accompanying drawing thereof.

Fig. 1 is a partial schematic sectional view of the present utility model.

Fig. 2 is the schematic representation of impeller blade and cross section of fluid channel.

Fig. 3 is runner and imports and exports schematic representation.

As shown in Figure 1, 2, the high pressure peripheral pump is formed 120 watts of motor power (output)s, 2800 rev/mins of rotating speeds by motor, the pump housing 4, axle 5, double shrouded wheel 1, runner 3, pump cover 2 and Sealing 6 etc., the diameter of impeller 1 is 6 centimetres of φ, thick 0.5 centimetre, the every lateral lobe sheet of impeller is 64, and the area of striking waters of per two blades 7 that the impeller left and right sides is arranged side by side is 0.125 square centimeter, the sectional area of runner 3 is 0.27 square centimeter, after measured, when this pumping head was 50 meters, flow was per hour 60 liters.
