Vertical slurry pump is a vertical single stage single suction
cantilever type centrifugal pump structure, impeller for the
semi-open impeller, impeller suction side extension is equipped
with a stirring blade.The pump is connected to the motor by an
elastic coupling, and the pump rotates clockwise from the direction
of the motor.
Pump assembly sequence
1, the double row bearing installed on the pump shaft, successively
into the bearing sleeve and the upper end bearing inner ring.
2. Load the pump shaft containing the bearing into the bearing
body, and install the bearing sealing gland and the water retaining
3. Install the upper bearing, bearing gland, bearing sleeve and
locking round nut in turn.
4. Adjust the bearing clearance: adjust the shaft to the direction
of the lower end of the bearing body until it cannot be
adjusted.Fix one round nut, another round nut is not fixed, use pry
bar, dial out the axial clearance, the general clearance is 0.015 ~
0.025mm.Then, tighten the nut and install the pump coupling.
5. Install and fix the connecting pipe, fixed plate, back cover,
impeller, pump body, bend pipe and outlet pipe.Note: The clearance
between the front end of impeller and pump housing is 2 ~ 2.5mm.
6. Install the motor base and the motor with electric
connection;That is to complete the entire pump assembly process.
7, the pump disassembly according to the opposite steps above.
Applicable scope of pump
Vertical slurry pump is mainly used in environmental protection,
new building materials, coal washing, municipal engineering,
thermal power, gas coke plant, oil refineries, steel mills, mining,
paper industry, cement factories, food factory, printing and dyeing
and other industries, and steam concrete pumping thick fluid, heavy
oil, diesel, dirty fluid, mud, mortar, sand flow and city PaiWuGou
floating sludge, as well as containing coal, ash liquid.It can also
be used in chemical, pharmaceutical and other industries to suck
fluid and corrosive liquid containing sand and slag.
Based on the actual use environment and conditions of customers,
our company has made the following improvements on the pump:
1. Wear resistance components are added to the raw materials of
overcurrent components, and the sizes of some overcurrent
components (such as impeller blades) are thickened.
2, thickened the pump center shaft, from the original centripeal
ball bearing changed to double row tapered roller bearing, greatly
increased the pump shaft torque force.
3. Three seals were added in the seal place to improve the seal
degree of the pump.
