Abstract
The utility model discloses durable sand pumps comprising a drive pulley, a main shaft, a pump base, a splash plate, a water sealing element of abrading block style, a left pump casing, a right pump casing, a liner, a splash lining board, a water-inlet lining board, a blade wheel, a water-inlet board, a water-inlet joint and a sand-outlet joint. The sand pumps are a left pump body and a right pump body, the liner is provided on the inner side of the pump casing which forms a pump chamber with the water-inlet lining board and the splash lining board arranged on the two sides of the pump casing. The performance of the wear proof of the whole pump body is good, the liner can be changed, and thereby prolonging the service life of the pump body. The sand pump employs water sealing element of abrading block style, and the sealing efficiency is good. The vanes of the blade pulley can prolong the operation surface, thereby improving the delivery lift of the sand pump and the production. And further the wall thickness of the sand pump is thinning, thereby reducing whole weight of the pump and saving the production costs.
Description
The utility model belongs to the technical field of centrifugal pump, is specifically related to a kind of architecture advances of transh pump.
Present sand pump is mainly used in rivers and adopts the sand shipborne equipment.Two kinds of high alloy cast steelpump and plain cast iron pumps are arranged, and all are monolithic cases, and pump case is integrated, and volume is big, heaviness, and inconvenience is installed.Though the high alloy cast steelpump is wear-resisting, price is more expensive, and after the part mill leaked, whole housing is disposable to be scrapped, and cost is higher; The plain cast iron pump, wear-resisting property is poor, increase volume and wall thickness for increasing the service life after, comparatively stupid growing sturdily.And the wheel blade of sand pump impeller exists angle outside, and working surface is little, and water absorbing capacity is poor, and lift is short, changes shortcomings such as frequent.It is oil sealing sealing that sand pump adopts cushion rubber, and sealing effect is poor, all not wear-resisting with asbestos rope packing material, and packing is serious to the axle damage, needs often to change.
The purpose of this utility model is to provide a kind of wear-resisting sand pump, has sealing, wear-resisting property is good, the characteristics of long service life.
The wear-resisting sand pump of the utility model is made up of drive pulley, main shaft, pump seat, manger board, abrading block formula water seal part, left pump case, right pump case, lining, dash liner plate, water inlet liner plate, impeller, water inlet plate, water supply connector and the joint that shakes out, pump seat is connected by bolt with manger board, left side pump case is connected with manger board, right pump case is connected with the water inlet plate, left and right sides pump case fastens and is connected by bolt, the ring bush that conforms to it in the inside pump casing setting, by manger board one side the dash liner plate is set, by water inlet plate one side the water inlet liner plate is set, forms pump chamber between lining and two liner plates; Main shaft is arranged in pump seat and the pump chamber by bearings, and the bearing two ends are provided with bearing gland, and front-end of spindle is provided with drive pulley, and the rear-end of spindle in the pump chamber is installed impeller, and abrading block formula water seal part is arranged on the main shaft section between pump chamber and the pump seat; Enter joint and be connected with the pump housing by the inlet damper cover, pump housing bottom tangent direction is installed the joint that shakes out.
Described abrading block formula water seal part is made up of water seal and hydraulic gland, and hydraulic gland is cup-shaped, is enclosed within on the water seal rotor.
The left and right sides pump case of the utility model sand pump, its material is a HT200 cast iron, inside pump casing is provided with lining, lining and two side plates are cast by cast steel, constitute wear-resisting main body, and whole pump housing wear-resisting property is obviously improved, lining is replaceable, thereby prolongs pump housing working life; This sand pump adopts abrading block formula water seal part, good sealing effect; Impeller blade lengthening working surface improves the lift and the output of this sand pump; And this sand pump wall thickness reduction reduces the overall weight of pump, thereby saves manufacture cost.
Below in conjunction with accompanying drawing the wear-resisting sand pump of the utility model is described further:
Fig. 1 is the sectional view of wear-resisting sand pump plan view;
Fig. 2 and Fig. 3 are respectively the plan view of Fig. 1 impeller and the sectional view of left view.(magnifying state)
As shown in the figure, wear-resisting sand pump is by drive pulley 1, main shaft 4, pump seat 5, manger board 7, abrading block formula water seal part 17, left side pump case 9, right pump case 10, lining 12, dash liner plate 8, water inlet liner plate 13, impeller 11, water inlet plate 14, the water supply connector 15 and the joint 16 that shakes out are formed, pump seat 5 is by being bolted on the hull, pump seat and manger board 7 are connected by bolt, left side pump case 9 is connected with manger board, right pump case 10 is connected with water inlet plate 14, left and right sides pump case fastens and is connected by bolt, at the ring bush 12 that the inside pump casing setting conforms to it, form pump chamber between lining and two liner plates; Main shaft 4 is arranged in pump seat and the pump chamber by 3 supportings of two mouthfuls of bearings, and the bearing two ends are provided with bearing gland 2, and front-end of spindle is provided with drive pulley 1, and the rear-end of spindle in the pump chamber is installed impeller 11, the working surface lengthening of impeller blade, as shown in Figure 2; On the main shaft section that abrading block formula water seal part 17 is arranged between pump chamber and the sand seat; This water seal part is made up of water seal and hydraulic gland, and hydraulic gland is cup-shaped, is enclosed within on the water seal rotor, between hydraulic gland and the manger board felt is set, and prevents that sandstone from entering.Enter joint 15 and be connected with the pump housing by the inlet damper cover, pump housing bottom tangent direction is installed the joint 16 that shakes out.
