Abstract
The utility model relates to an arc bond scaleboard two-layer pump crust which is used for the slush pump. The utility model consists of an over cover, a scaleboard, a silting layer, a pump mouth, a pump crust as well as a positioning fixing mouth. A two-layer pump crust consists of an inside lining which is formed by the over cover and a plurality of scaleboards and the silting layer is arranged in the middle. An inside lining positioning limit mouth inside the pimp mouth of the over cover. The utility model adopts the arc bond scaleboard to form a flowing passage, uses an integrally casting over cover forming a supporting crust. The inner and the outer layers can be designed according to the standard size of the pump, thus the size of the flowing passage can be assured. The utility model is of reliable performance, low producing cost, and the abrasion of the flowing passage is uniform, the scaleboard changing is convenient, and also the localization, serialization as well as standardization can be realized.
Description
Technical field: the utility model relates to the double-deck pump case of a kind of dredge pump arch block combined type liner plate of machinery.
Background technique: be used in the pump case that the dredge pump arch is built combined lining board, domestic all is to transform lining with single pump case of scrapping.Because the wear condition difference of monoshell pump, can't guarantee the channel size behind the lining, can't realize standardization, seriation, normalized production.External double-deck pump case is assembled by block cast formula inner bag and split shell, and inner bag is made difficulty, the expense height, and performance is difficult for guaranteeing that when concentrated wear was lost efficacy, the integral pump courage was scrapped, and can't repair, and buys difficulty, costs an arm and a leg.
Summary of the invention: the purpose of this utility model is to overcome above-mentioned shortcoming, provides a kind of dredge pump arch to build the double-deck pump case of combined type liner plate.Problems such as the inhomogeneous and expense height of runner wearing and tearing have mainly been solved.The purpose of this utility model is such realization, dredge pump arch build the double-deck pump case of combined type liner plate by: pump case, pumping hole, overcoat, liner plate piece, filling bed, positioning spigot constitute.The liner that overcoat and several liner plate pieces arch are built into is formed double-deck pump case.There is filling bed the centre, is provided with the liner positioning spigot in the pumping hole inboard of overcoat.This product is taked arch to build the combined type liner plate and is formed runner, form supporting shell with block cast formula overcoat, inside and outside bilayer all can design by the standard measure of pump, thereby guarantee that channel size is accurate, reliable performance, low cost of manufacture, full runner wearing and tearing are evenly, liner plate is changed convenient, and can realize production domesticization, seriation, standardization, normalized production.
