Abstract
The utility model relates a general high-efficiency pump for cold water and hot water which is suited to pumping cold water and hot water. The utility model mainly comprises a C-shaped water flow gutter 12, a pump body 1 of the convexo-concave seal groove 4, an impeller 2 provided with a bucket-like blade 3 and a convexo-concave seal groove 4, a rubber seal ring 5, a bracket 6, a mechanical seal ring 7, a dehydrated film 8, an electric motor 9, an inlet opening 10 and an outlet opening 11. The utility model has the advantages of high efficiency, long life-span, and a wide adapting range; therefore, the utility model is suited to supplying water for buildings and boilers.
Description
The utility model relates to the general high effective pump of a kind of hot and cold water.Be applicable to and require lift (pressure) higher (6～20kg) hot and cold water is pumped work.
Previously used water pump is owing to be the precision-fit of utilizing between two-sided radial inflow dentation copper impeller, the pump housing and the support three, carries out high speed rotating and draws water, and its shortcoming is a lot.Mainly contain the following aspects: 1, because the gap between parts is little, two-sided radial inflow dentation copper impeller is easy to wearing and tearing, move about 2-3 individual month, and the gap just can become greatly, causes that pump head (pressure) declines to a great extent and influences normal use.2, owing to be to keep pressure of supply water by gap very closely, so its pressure is difficult to reach more than the 6kg, and flow is very little.3, the gap between parts is little, is difficult to assembling during production, and manufacturing efficiency is low.When 4, being used to pump hot water, the copper impeller is expanded by heating, and stuck mutually with the pump housing, causes that motor burns out.Therefore can not be used for hot water pumps.
The purpose of this utility model provides the general high effective pump of a kind of hot and cold water, and its particular design can overcome the deficiencies in the prior art, improves technical level, and improves the adaptive capacity of product to market.
The utility model is achieved in that the concavo-convex grooved ring that has two bundles and impeller to match in pump housing inboard, and each is consecutively arranged to form every bundle grooved ring by a few circle seal grooves.One " C " type fortune tank is arranged between the concavo-convex grooved ring of two bundles, and an end of fortune tank is a water inlet, and the other end is a water outlet.Be furnished with the concavo-convex grooved ring that two bundles and the pump housing match in the impeller inboard, each is consecutively arranged to form every bundle grooved ring by a few circle seal grooves.Between the concavo-convex grooved ring of two bundles, be evenly equipped with bucket-shaped blade.During installation, the pump housing and impeller are with the mutual interlock of the two concavo-convex grooved rings of bundle.Driven by motor impeller rotation during operation, bucket-shaped blade gives the past water outlet of a pipeful of bucket of sending to from water inlet of water, finishes whole pump up water process.
The utility model was compared with former water pump, and the life-span of impeller extends to 8～10 times, and resource is fully used; The novel designs of the pump housing and impeller makes installation more convenient, and no matter the hot water or cold water all can normally pump, and using scope is wider; Flow has improved 2～3 times with lift than existing water pump, and water pump and efficiency of motor all significantly improve, and is particularly suitable for the whole usefulness that boiler equipment is done water supply of scalding.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural drawing of the general high effective pump of hot and cold water of the utility model preferred embodiment;
Fig. 2 is the working surface view of the pump housing of the general high effective pump of this hot and cold water;
Fig. 3 is the side complete section figure of the pump housing of the general high effective pump of this hot and cold water;
Fig. 4 is the working surface view of the impeller of the general high effective pump of this hot and cold water;
Fig. 5 partly cuts open figure for the side of the impeller of the general high effective pump of this hot and cold water.
Fig. 1 is the structural representation of the preferred embodiment's of the utility model the general high effective pump of hot and cold water.This pump comprises: the pump housing 1 (seeing accompanying drawing 2,3 for details), impeller 2 (seeing accompanying drawing 4,5 for details), rubber seal 5, support 6, mechanical seal ring 7, dehydration film 8, motor 9, water inlet 10, water outlet 11.The concavo-convex grooved ring 4 that has two bundles and impeller 2 to match in the pump housing 1 inboard, each is consecutively arranged to form every bundle grooved ring by a few circle seal grooves, one " C " type fortune tank 12 is arranged between the concavo-convex grooved ring 4 of two bundles, one end of fortune tank is a water inlet, the other end is a water outlet, be furnished with the concavo-convex grooved ring 4 that two bundles and the pump housing 1 match in impeller 2 inboards, each is consecutively arranged to form every bundle grooved ring by a few circle seal grooves, is evenly equipped with bucket-shaped blade 3 between the concavo-convex grooved ring of two bundles.During work, the bucket-shaped impeller high speed rotating of driven by motor from the water inlet suction, constantly pressurizes through bucket-shaped impeller, makes water outlet have the water of very big flow and elevated pressures to flow out, and has guaranteed the key technical indexes---high-lift, big flow, the high efficiency of water pump.In the utility model, the pump housing 1 is a Cuprum alloy, and the bucket-shaped blade 3 of impeller 2 is a stainless steel.The power range of motor is 0.3～3kw, and being suitable for voltage range is single, three-phase 200～400v.
