Abstract

The utility model relates to a high-efficiency wear-resistant mud sand pump, and belongs to the contamination drainage device. The utility model cleans the sand, drains the contamination, saves the labor, the material and the energy, and has convenient operation. The utility model is used for mines, oilfields, lakes, rivers, ponds, and urban environmental protection. The utility model is composed of an electric motor, a supporting seat, a pump body connecting pipe, a pump shell, a main shaft, an impeller and a protective cover. The main shaft is divided into an upper bearing, a middle bearing and a lower bearing. The lower bearing, the impeller, the pump shell and the elbow inner wall are pressed by good synthetic rubber materials by purpose made formula. The service life extends 3-6 times than the prior art. When the utility model is operated and run, the sand and the sewage are drained from a flexible pipe. The utility model has the advantages of high efficiency, wear resistant, corrosion resistance, low cost, convenient installation and use, etc.

Description

The high-efficiency abrasion-proof sand pump

The utility model relate to a kind of improved sand pump, particularly a kind of can energy saving, easy to maintenance, lift is high, noise is little, pollution-free and high-efficiency abrasion-proof sand pump that automaticity is high.Belong to the waste removal equipment technical field, be mainly used in urban environmental protection, mine, oil field, lake, river course and large-scale preparation of ponds, blowdown is required.

Existing sand pump mainly is made up of motor, supporting base, pump housing adapter, main shaft, impeller, protective housing.Can be used for blowdown handles.When motor operation, driven the impeller rotation in the pump case, sewage and silt particle have been discharged by flexible pipe.But this sand pump is because technology is backward; not corrosion-resistant; each parts wear-resisting property is poor; dead time is more, and maintenance load is big, reduces manufacturing efficiency; influence the blowdown work of treatment; and bearing only reaches about two months working life, does not reach high efficiency, at full capacity and energy-conservation, saving of labor, the material-saving purpose of producing fast.

Task of the present utility model is that a kind of improved high-efficiency abrasion-proof sand pump will be provided, and it adopts advanced technological method, produces into common sand pump life-span 3 to 6 times waste removal equipment, to reach the ideal effect that blowdown is shaked out.

Task of the present utility model is finished as follows: the high-efficiency abrasion-proof sand pump is put into 1: 1.8 sewage silt particle of concentration, start transmission device, drive main shaft and impeller high speed rotating, silt particle is sucked in the protective housing, by a kind of pressure that turns round and produced, silt particle is gushed by flexible pipe row, so far just reached the purpose of sand removal blowdown.The utility model is simple in structure, design code is reasonable, and is easy to install, and cost is low, and the efficient height is wear-resisting, corrosion-resistant, economizes on electricity 20 percent, reduces maintenance expenses and reaches about 70 percent.Concrete structure of the present utility model is provided by following embodiment and accompanying drawing.

Fig. 1 is the sectional drawing of a kind of concrete structure of the utility model.

Fig. 2 is that the utility model is installed the integrally-built intention of facing in back.

With reference to accompanying drawing, a kind of hanger of high-pressure anti-wear sand pump [1] is welded on the upper mounted plate [2], upper mounted plate [2] has two to four root posts [3] to use bolt with bottom plate [5], bottom plate [5] connects supporting base [6], supporting base [6] supports motor [4] securely by bottom plate [5], connect the pump housing under the supporting base [6] and take over [7], the pump housing is taken over [7] and closely is connected on the pump case [10], pump case [10] links to each other with delivery hose [8] with elbow [9], and pump case [10] is following to be connected with protective housing [11].The shaft joint of main shaft [13] below zygote [12] and motor [4] closely is fixed together, and main shaft [13] vertically packs in the wheel hub of rubber impeller [14], uses bolton.Here main shaft [13] is made up of upper bearing (metal) [15], middle (center) bearing [16], lower bearing [17], upper bearing (metal) [15] is to be processed into the high-quality steel with middle (center) bearing [16], lower bearing [17] is made with the high-pressure anti-wear rubber material, it in it high-quality steel iron pipe, outer lining one deck high-pressure anti-wear rubber, by the constantly draining of lubricated weep hole [18], play the effect of lubricated inside and outside cover.The rubber impeller [14] that main shaft [13] is connected selects for use the high-pressure anti-wear rubber material to be pressed into.Rubber impeller [14] can be pressed into the rubber tree leaf that two to four or multi-disc do not wait according to model specification.Pump case [10] inwall, elbow [9] inwall are that utilization high-quality synthetic rubber is made lining, make it not fragile, durable in use.

In sand removal blowdown process; according to most preferred embodiment described above; when carrying out the equipment operation; the upper bearing (metal) [15] of main shaft [13], middle (center) bearing [16] are in supporting base [6] top; the pump housing of supporting base [6] lower end is taken on [7] and is drilled with two to four or a plurality of lubricated weep hole [18]; when machine runs up; by rubber impeller [14] rotation potential energy and last stamping press; constantly reciprocally water is released from lubricated weep hole [18], so not only do not corrode the rubber bush bearing [17] of lower end and can also play lubricating bearings and the effect of protection motor [4] normal operation.

Claims

1, a kind of high-efficiency abrasion-proof sand pump, taking over [7], pump case [10], elbow [9], delivery hose [8], protective housing [11] and slewing gear by hanger [1], upper mounted plate [2], bottom plate [5], column [3], supporting base [6], motor [4], the pump housing constitutes, it is characterized in that main shaft [13] tightens together by the shaft joint of zygote [12] below motor [4], main shaft [13] is made up of upper bearing (metal) [15], middle (center) bearing [16] and lower bearing [17], and main shaft [13] vertically packs in the wheel hub of the rubber impeller [14] in the pump case [10].
