slurry pump structure
The 1 motor; 2 motor seat; 3 joint bearing box; 4; 5 axle tube; 6 spindle; 7 pump seat; 8 filler basin; 9 impeller; 10 output rubber tube; 11 pump shell
(1) use
In the rural areas is mainly used as a stool, river, river, the slurry feed suction conveying watering, instead of the shoulder arm, and for flood, drought with, also car bang tou on mud, manure production. Can also be used as a simple flow of rural fire pump.
It can used for municipal, chemical, printing and dyeing, pharmaceutical, food industries such as shipbuilding, casting, pump thick liquid, foul liquid, Lake shaped body, the flow of sand and city river flow sludge; can also be used as a small coal mines fluid containing mud gravel.
If combined with high pressure pump, water gun, the composition of hydraulic mechanized earthmoving machine, used for ground leveling, dredging, drilling and other small-scale water conservancy project River and pond excavation and transportation, as well as the city’s air defense engineering, underground engineering.
(2) the structure of the pump is a single-stage single suction vertical centrifugal pump, the fluid along the axis of the pump shaft is 70 degrees to the direction of outflow, the main components of a volute, impeller, pump seat, shaft, a support cylinder, motor, motor etc.. Volute, pump seat, motor base, cast iron impeller nut is, wear resistance, good corrosion resistance, easy processing.
Impeller for the three single circular arc curved leaves, use a semi enclosed impeller and the balance hole, and the use of malleable iron, so high strength, corrosion resistance, easy processing, good passing ability, high efficiency.
In order to reduce weight and reduce the amount of turning, the pump shaft is made of quality carbon steel cold drawn steel.
The pump seat is provided with the four skeleton oil seal and sleeve to prevent shaft, wear, prolong the service life of shaft.
The pump can be vertical or inclined to use, small occupied area, scroll be buried in the working media work, easy to start, without water, from the direction of motor rotation is clockwise direction to see the end of work.
Supporting power of the pump is vertical and horizontal dual-purpose motor, mounted detachable motor horizontal when necessary, towing other machines.
Switchboard length with a variety of specifications, the use of units in order to suit one’s measures to local conditions according to the use of the.
(3) Notice
The pump power must be used in three-phase four wire system, if there is no grounding wire must be installed to prevent leakage,. When working, should be in the nearby equipped with circuit fuse and switch motor match, in order to prevent the impeller debris stuck burn out the motor.
The pump can not install any basic device can run, as long as the leaning can be firmly fastened with rope, when necessary to prevent accidents. After starting to check the direction of motor rotation, shall not be reversed more than a minute.
When the suction feeding liquid containing more weeds, Tie Si, wood, bricks and other debris, must have prior to remove, and can be taken and put Tie Si basket method, to prevent debris suction cause the impeller broke, the death card and pipe blockage accident pump.
The pump body should be given the short-term water in the suction and other dirty things, in order to flush the internal pump and pipeline.
The work in the open air, the motor should be installed to prevent rain shield, immersion motor.
In the bottom, the bottom of the pool suction should be hanging in the three leg, and a mobile operation on the buoy or a boat, the earthwork operations, high pressure water gun rushed to break the clods of diameter not greater than the suction port 1 / 3.
The provisions of the pump speed is the highest speed pumps, shall not increase; reduce the speed of the use is not limited, but the effect was significantly lower.
In the pump suction sent thick mud, thick liquid or high head, long distance transporting mud, load will be reduced, but can not be used to change the structure of the methods to increase the load.
The general run 1250 hours or so, regular maintenance of pump, remove the pump seat check bearing and pump seal, please see note cleaning and replacement of parts installation.
⑩ when long time stop, should the open, dry parts and in the relative motion of joint surface coated with thin oil, stored in a dry place for later use.
(4) removing
The disassembly of the motor and the fixed plate, pipe.
The removal of volute and impeller nut, light pry the back surface of the impeller, and the impeller key.
③ removing driven half couplings, and then removing key, then the motor seat removing, and the support tube separation.
The dismantling the pump seat and the support cylinder bolt, to separate.
From the shaft sleeve and the bearing disassembly.
(5) installation
Whether there is defect of all parts for inspection, all paper pad to both sides to be coated with a thin layer of butter.
The seal must be filled with butter into the pump seat, then loaded on the bearing in the bearing, and add 2 / 3 butter.
The shaft sleeve is mounted on a O type sealing ring and buttered.
The bearing cover is arranged on the motor seat, mounted on the bearing with 2 / 3 butter; put a pad of paper, oil retaining ring, mounted on the shaft and the supporting cylinder is fixed by screw.
⑤ put a pad of paper, pump installed base, shaft sleeve, keys and impeller impeller nut, screw, put the paperback accessories.
We use wood hammer or lead hammer percussion pump shaft, the shaft shoulder against the bearing, remove the bearing cover, paper pad is installed, the bearing cover, the axial motion is greater than 0.5 mm, with a finger toggle impeller, making it flexible rotation.
And put on the pad of paper mounted pump shell, is fixed by bolts and installed filter. Then the fingers toggle impeller, flexible rotation, vertical assembly.
The pump shaft is provided with a key and a driven shaft coupling, the shaft of the motor is installed on the key and the active coupling, and then the motor and the motor seat fixed with bolts. Installed after the required axial clearance between the active coupling and driven shaft coupling should be 1-1.5 mm.
