Description
Technical field
The utility model relates to the light-duty slag stock pump of a kind of corrosion-proof wear, belongs to field of fluid machinery.
Background technique
Light-duty slag stock pump basic structure form is mono-hull, the centrifugal type slurry pump of single-stage, single suction cantilever, horizontal, axial suction.This pump type is simple in structure, and maintenance is convenient, and low cost of manufacture, mainly for delivery of corrosion and the abrasion slurry of solid content≤35%.Be widely used in the industries such as metallurgy, mine, oil, chemical industry, coal, electric power.
The light-duty slag stock pump of corrosion-proof wear of conventional construction, as shown in Figure 1, flow passage components mainly contain the pump housing, impeller, pump cover, wherein impeller is double shrouded wheel, double shrouded wheel is for reducing volumetric loss, ensure pump efficiency, the matching gap of impeller and the pump housing must be controlled in 2mm, this just causes oarse-grained slurry to enter behind this gap, cannot pass through smoothly, after operation a period of time, the pump housing, impeller, pump cover all will be denuded seriously, cause the matching gap of impeller and the pump housing to increase, cause pump performance to decline, greatly increased spare part maintenance cost.In addition, for locating the shaft seal positioning ring of mechanical seal on pump shaft, be to pack into from the inner chamber of pump cover, compress mechanical seal by front end, make it press closer backward the interior along front-end face of shaft seal positioning ring, the outer ear end face of shaft seal positioning table presses closer pump cover, realizes the axially locating of mechanical seal.Because shaft seal positioning ring major part is positioned at pump cover inner chamber, directly contact with medium, be very easily abraded and corrode, in addition, the inconvenience of interior structure installing/dismounting, need to dismantle the whole pump housing while adjusting mechanical Packing spring decrement, be not easy to observe and safeguard, cause installation and maintenance user cost high.
Model utility content
The purpose of this utility model is the problem such as the slag stock pump pump housing and pump cover quick abrasion, mechanical seal installation and maintenance inconvenience for solving conventional construction, and provides a kind of corrosion-proof wear light-duty slag stock pump.
The purpose of this utility model is achieved through the following technical solutions:
The light-duty slag stock pump of a kind of corrosion-proof wear of the present utility model, comprises the pump housing, impeller, wearing plate, pump cover, machine envelope positioning ring, pump shaft;
The front end outer of machine envelope positioning ring is processed with the ladder positioning table matching with pump cover endoporus, processing organic envelope locating slot in edge in the front end of machine envelope positioning ring;
Pump housing rear end encapsulates by pump cover, impeller is by pump shaft and the inner chamber that is arranged on the pump housing and pump cover, and on the pump cover of impeller rear end, be fixed with the wearing plate that front-end face is planar annular, mechanical seal is installed in pump shaft and pump cover joint, machine envelope positioning ring is inserted in from the pump shaft of pump cover rear end, by being socketed locking nut in machine envelope positioning ring rear end, make ladder positioning table and the pump cover endoporus axially locating of machine envelope positioning ring front end outer, the machine on the interior edge of a machine envelope positioning ring front end groove that binds is realized the rear end axially locating of mechanical seal.
Described impeller adopts open type eddy current impeller.
Beneficial effect
Slag stock pump of the present utility model, by removable wearing plate is set between impeller and pump cover, has reduced the replacement cost of vulnerable part; Adopt external mounted for the shaft seal positioning ring of locating mechanical seal on pump shaft, facilitate mechanical seal installation and maintenance; Adopt open type eddy current impeller, reduce the wearing and tearing to the pump housing.
