I. Overview 
 %%%% 80DGL-75 pump is single stage, single suction sectional centrifugal pumps for the process of mine shaft dug to send with the sediment in the muddy water drain. 
 Specific requirements on water quality are: the volume concentration ≤ 25%, the proportion of ≤ 1.15, the solid particle diameter ≤ 0.2mm 

 %%%% Second, the pump model significance 
 %%%% 80 - pump inlet and outlet diameter (mm) 
 %%%% DGL-pump multi-stage vertical hanging 
 %%%% 75 - Single lift (m) 
 %%%% From the original motivation for direction, the pump for the counterclockwise rotation. 

 %%%% Third, the structure shows 
 %%%% Pump and motor housing through the bracket, bracket welded in the channel on the hanger. Hanger with the upper sheave, the weight of the entire unit from the rope through the rope round commitment. 
 %%%% End of the pump outlet pipe parts B and membership help the water pipe connected to the pump outlet flange, and then through the telescopic tube, over water, a water pipe connected with the outlet pipe bearing support, bearing in fixed hanger at the top. 
 %%%% Outlet pipe support between the seat and turn the pump with gate valve, check valve and extension tube. 
 %%%% In order to facilitate operation of valve and pump with the lower part to the hanger at the top of the ladder parts, ladder, step under the lower part of Taiwan, with step hanger at the top of the console table and with a barrier. 
 %%%% The pump suction pipe is φ100 hose, hose at the bottom with the bottom gate. A check valve and water pipe fitted between the water pipe (water pipe parts should be drilled in the field, change the wire assembly.) Open the valve on the water pipe, the water in the outlet pipe can fill. Pump and into the water for use when driving. 
 %%%% This pump uses JBLBS vertical flameproof motor, motor housing with water cooling units. 
 %%%% For the axial water pump, water from the next paragraph and the next bearing water channels on both sides of the body composition. 
 %%%% Under the pump bearing seal is composed of two oil seal (in the interval to seal the oil Quan) and a soft filler composed of carbon fiber. Under its main role is to prevent grease within the bearing to be pumped into the pump. Balanced set of drums in front of a wheel block, similar to the vortex pump impeller. Its role is to clear the muddy water into the balancing device in the part of the sediment. When the balance device is worn, it has to reduce the pressure balance chamber. 
 %%%% And the middle section of the pump inlet, the middle section with the water between the use of rubber O-ring seal. 
 %%%% Bearing bracket parts of the balance chamber has two holes, a return pipe installed, install the connector to another seat, the part of the water of the cooling system to the motor, the connectors can be installed seat pressure gauge to check the motor cooling water pressure. 
 %%%% Pump flow components using ductile iron, sealing ring, impeller seal ring, sets of guide vanes, impeller, gear sets, balance drum, balanced sets of wear parts such as cast iron with wear-resistant.
