PN mud pump product introduction
Flow manufacturing using wear-resistant alloy material of PN typeslurry pump, long life. 6 "and 6" mud sand impeller and shaft by screw thread, 8 "and 8" above the mud pump, the pump body is larger, the open structure level, disassembly and convenient maintenance.
Seal packing seal used in general, work should be injected into thehigher than the working pressure of 1 kg / cm ² of shaft seal water.Model PN mud pump, the transmission direction, rotates in counterclockwise direction (1, 2, 3PN clockwise) Ye Lun screwconnected with the shaft, if the opposite direction, Ye Lun will fall off from the shaft.
PN mud pump structure feature
1, Reasonable structure, convenient repair: pump head part usedbefore and after the door structure, repair without dismantling piping, just move the motor backwards, can be disassembled andrepair the pump.
2, High concentration, no clogging: conveying pulp concentration up to 6%;
3, Cavitation erosion resistance, long service life: the actual service life than ordinary paper pulp pump can be increased by 2-3 times;
4, High efficiency, energy saving: efficiency than ordinary pulp pumpan average of 3-10 percentage points, saving energy and reducing consumption, up to 15-30%
5, The impeller and the guard board clearance can be adjusted in a timely manner, maintain higher working efficiency. The pump above the pump body is larger, the structure of open, disassembly andconvenient maintenance.
PN mud pump structure and type meaning
PN slurry pump, composed of 10 parts: the pump body, cover,impeller, guard board, packing box, shaft bracket, bracket, rear cover, cooling pipe, a pump seat.
PN mud pump model significance: such as 2PN mud pump 2--- spit out diameter (mm number divided by 25 income value) P--- impurity pump N--- mud
PN mud pump application and scope
1, PN type slurry pump single stage single suction pump (vertical,horizontal) has the characteristics of long service life, simple structure, reliable running etc.. Delivers maximum concentration by weight is 50%.
2, Used in mining, metallurgy, municipal construction, chemical industry, printing and dyeing and other suction flow sand, mud,muddy small mud liquid with.
3, In the countryside, the mud pond mud fluid, feces, pulp beveragesuction; can also be used for City factory transport ore fluid,underground suction sand and mud, yellow.
PN mud pump structure using the matters needing attention
(1) The disassembling and assembling according to the assembly diagram.
(2) A pulp inlet pipe should not be anxious brush bending, as far as possible downward sloping (DIP 30 °), easy to exhaust.
(3) Should grasp the running period of regular replacement of spare parts and bearings to prevent accidents.
(4) Into the slurry is too small not to run, so as not to cause vibration and slurry precipitation.
(5) Application of water rinse to prevent clogging the pump is stopped.
(6) The type of pump in addition to 12PN mud export level, others are vertical upward.
(7) PN type pump shaft seal water must be added a certain amount of water, the general work flow of 1-3%, the pressure should begreater than the working pressure of 1 kg / cm 2.
(8) 1PN, 2PN, 3PN, 2PNL, 3PNL steering motor direction is clockwise, 4PN, 6PN, 8PN, 10PN, 12PN steering motor direction is counter clockwise.
(9) In this type of pump in general use.
(10) The pump is not allowed to reverse parking.
