Abstract
The invention provides a vertical-type wear resistant submerged pump, which can not only significantly improve wear resistance of transflux parts, but also better can solve bearing problems of a major axis and greatly improve rotation precision of an impeller. The invention uses the following technical scheme to solve technical problems: a pump is provided with a grease lubrication bearing above liquid level and a water lubricated bearing below the liquid level; materials of the impeller and a pumping chamber in the pump are composite wear resistant materials which contain 10-98% (weight) of abrasive grains and 2-90% (weight) of resin binders. After the water lubricated bearing is arranged below the liquid level, the stress state of the major axis is greatly improved and the rotation precision of the impeller is also significantly improved. The bearing service life can be greatly prolonged under the premise of not increasing the design strength of the grease lubrication bearing and the major axis. The impeller and the pumping chamber, which are manufactured by using the composite materials containing abrasive grains and resin binders as chief ingredients, can not only technically achieve high manufacturing accuracy, but also can have a better wear resistance.
Description
Affiliated technical field
The present invention relates to a kind of vertical submerged pump, the vertical-type wear resistant submerged pump of the solid-liquid two-phase flow of abrasion is arranged in particular for conveying.
Background technique
Under Water Pumps has easy for installation, need not to consider the advantage that fluid leaks.But the Under Water Pumps of prior art exists following significantly not enough: first flow passage part mostly is abrasion resistance alloy, rubber manufacturing greatly, can not satisfy the requirement of carrying strong abrasion medium; It two is that the bearing of Under Water Pumps all designs on liquid level mostly, impeller stretches under the liquid by the main shaft cantilever support, for guaranteeing that impeller inserts the needs of the degree of depth under the liquid, the jib-length of main shaft must design longlyer, therefore not only must increase the design strength of main shaft and bearing, and reduce the rotating accuracy of impeller.
Summary of the invention
For solving the above-mentioned deficiency of prior art, the invention provides a kind of vertical-type wear resistant submerged pump, not only can obviously improve the wear resistance of flow passage part, can solve the support problem of main shaft preferably simultaneously, and the rotating accuracy of impeller can be improved greatly.
The technical solution adopted for the present invention to solve the technical problems is: the pump liquid level is to be provided with the grease lubrication bearing, being arranged with water lubriucated bearing, the impeller of pump, the material of pumping chamber are the composite abrasion resistance material of the resin-bonded agent of the abrasive grain that contains 10-98% (weight) and 2-90% (weight) at liquid level.
It is lower and wear resistance is artificial preferably or natural abrasive that above-mentioned abrasive grain is generally cost, as silicon nitride, silicon carbide, corundum, garnet, emery, zirconium oxide etc.Can adopt a kind of abrasive material wherein, also can adopt several abrasive material combinations to strengthen the wear resistance of composite abrasion resistance material simultaneously.If only the mechanical strength of the composite abrasion resistance material of being made up of abrasive grain and resin-bonded agent can not meet design requirement, the mechanical strength that can add the auxiliary material raising impeller that is no more than 49% (weight) therein, these auxiliary material have cellosilk, fleece, French chalk, coupling agent, plasticizing agent etc., add and fashionablely add wherein a kind ofly, also can add wherein several.Skeleton can also be set on pumping chamber or impeller improve mechanical strength.Should make skeleton not be subjected to washing away of high-velocity fluid during design, make skeleton not frayed.
The invention has the beneficial effects as follows: after under liquid level, water lubriucated bearing being set, the force-bearing situation of main shaft improves greatly, the rotating accuracy of impeller also significantly improves, and just can improve the life-span of bearing under the prerequisite that does not increase grease lubrication bearing and main shaft design strength greatly.Adopting Main Ingredients and Appearance is impeller, the pumping chamber of the composite material manufacturing of abrasive grain and resin adhesive, not only is easy to realize higher accuracy of manufacturing on the technology, and its wear resistance is also better.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of one embodiment of the invention.
