Description
Technical field
The utility model relates to a kind of pump, especially relates to a kind of wear-resistant sand suction pump.
Background technique
Sand suction pump is made up of pump case, pump cover, impeller, pump shaft and bearing unit etc., connects and connect with two before pump cover is generally divided into, and be wherein positioned at sand inlet side and connect before the pump cover of sand inlet tube is called and connect, the pump cover of opposite side coupling shaft bearing is called that two connect; Also have some sand suction pumps to make an entirety by front connecing with pump case, pump cover now just only comprises one two and has connect.For the ease of processing, connect before of the prior art, two to connect, impeller is all adopt to be easy to cutting but the poor graphitic pig iron of wear resistance is made, the impact of opposing mortar that can not be permanent, is easy to wearing and tearing, fracture, makes the working life of existing sand suction pump very short.
Model utility content
technical problem:for the deficiency that prior art exists, one is provided to resistance to wear, shock-resistant, the sand suction pump of long service life.
technological scheme: the wear-resistant sand suction pump that the utility model provides, comprises that pump case, two connects, impeller and pump shaft, and impeller comprises impeller bodies and is positioned at for installing the core wheel of pump shaft in the middle part of it, and two connect and comprise two and connect main body and be positioned at the water tight compartment in the middle part of it; Some pump case connecting screw holes are provided with at two edges connecing main body, in the position that the rear port of described pump case main body is provided with position, quantity and described two connects the pump case connecting screw hole in main body, the corresponding nut of quantity or bolt, described two outsides connecing main body are provided with bearing support connector element; Its innovation is, described two connect main body adopts antifriction cast iron casting, water tight compartment adopt other can cutting ferro-alloy manufacture and be cast into two and connect in main body.Described other can the ferro-alloy of cutting can be common graphitic pig iron, or iron and steel, common spheroidal graphite cast iron etc.Described being cast into is pre-buried being cast into, and the water tight compartment of machine shaping directly can be adopted to be cast into two and connect in main body, also can connect being first cast into two for not shaping core iron in main body, more for further processing.Sand suction pump of the prior art, the conveniently processing of water tight compartment, connect whole two of main body and connect to comprising two and all adopt the graphitic pig iron being easy to cutting to manufacture, the wear resistance making two to connect is poor.The utility model breaches the constraint of conventional art, adopt different materials to manufacture to two different parts connect, impact larger two and connect main body to bearing mortar and adopt antifriction cast iron casting, to be positioned at two connect middle part by mortar impact less water tight compartment adopt other ferro-alloys being easy to cutting to manufacture, while the wear resistance that raising two connects, solve the processing problems of water tight compartment.
The sand suction pump arranged with the split of pump case main body is connect before the utility model is equally applicable to, now, the utility model comprise pump case main body and before connect, also be provided with some pump case connecting screw holes at the edge front connecing main body, the front port of described pump case main body be provided with position, quantity with described before connect the corresponding nut of the position of the pump case connecting screw hole in main body, quantity or bolt; The outside connecing main body before described is provided with sand inlet tube connector element.
In order to further improve the wear resistance of sand suction pump entirety, whole wearout partss that are subject to of the utility model handle all adopt antifriction cast iron manufacture, that is: described impeller bodies, pump case main body and before connect main body and all adopt antifriction cast iron to cast, before described pump case main body, the nut of rear two-port or bolt are cast into pump case main body, described core wheel adopt other can cutting ferro-alloy manufacture and be cast in impeller bodies, described sand inlet tube connector element be sand inlet tube adpting flange or some be cast into before connect nut or the bolt of main body, described bearing support connector element is bearing support adpting flange or is somely cast into nut or the bolt that two connect main body.Because be difficult to carry out cutting on antifriction cast iron, so, be cast into pump case main body, frontly connect the nut that main body, two connects main body, the female nut of tool can be adopted to be cast into, also can first be cast into as core iron with bloom, and then boring, tapping become nut on core iron; Equally, be cast into pump case main body, frontly connect the bolt that main body, two connects main body, the threaded bolt of tool directly can be used to be cast into, also can first be cast into threadless core iron, and then mantle fiber becomes bolt.The bearing support adpting flange adopted or sand inlet tube adpting flange, the once-through when casting, without the need to cutting.
In order to reduce the cost of the wear-resistant sand suction pump of the utility model, described antifriction cast iron can select white iron, and described other ferro-alloy of cutting can select graphitic pig iron or spheroidal graphite cast iron.
Further, in order to improve the toughness of impeller, occur fracture when preventing impeller to be subject to the impact of stone, described impeller bodies preferably adopts high chromium white antifriction cast iron.
beneficial effect: first, adopt antifriction cast iron and can the ferro-alloy manufacture of cutting respectively because two of the utility model sand suction pump connects main body and water tight compartment, what the contradiction solved due to wear resistance and workability caused two connects not wear-resisting difficult problem; Secondly, the method being cast into core wheel in high chromium white antifriction cast iron impeller bodies that impeller adopts, improves the toughness of impeller greatly, solves the problem that impeller is subject to being easy to when stone impacts brittle failure, improves the working life of sand suction pump.In addition, in pump case main body, frontly connect the cast-in bolt or nut that connect employing with two, and two connecing, the front adpting flange connecting design, while raising sand suction pump wear resistance, achieve the reliable connection of sand suction pump with simple structure, simplify production process.
