PNL series vertical dredging pump Overview: PNL series of vertical dredging pump with hydraulic, will be mixed by high-pressure water mud and sediment transported to the destination, the improved PNL pump high efficiency, over-current conditions, resistance Abrasion, long service life, widely used in beach, farm, river excavation, dredging dredging, river sand draw, coastal filling operations. Application: river reservoir dredging: The construction principle is to produce pressure water through the water pump, after the water gun sprayed high-speed water, cutting, crushing the sand, make it wet, disintegration, the formation of mud and mud mixture, and then stand Dredging pump and its delivery pipe to the designated location. By the clean water pump mud system, vertical dredging pump mud system and power distribution system consists of three parts. Vertical dredging pump system consists of vertical mud mud pump, floating body, high pressure water and so on. Clear water pump mud system: including water pumps, water pipes, high pressure water gun. Distribution system includes distribution boxes, waterproof cables. Structural features: 1. Pump by the pump, impeller, guard, electric frame and bearing assembly and other components. 2. The pump shaft seal rubber seal seal. 3. Pump rotation direction: viewed from the impeller inlet counterclockwise rotation. 4. Using the impeller to reduce impeller back pressure, to extend the life of the seal. 5. Flow components using wear-resistant cast iron, anti-abrasion.
Auger Bit
The auger bit adds a long deep spiral flute for effective chip removal.
Two styles of auger bit are commonly used in hand braces: the Jennings or Jennings-pattern bit has a self-feeding screw tip, two spurs and two radial cutting edges. This bit has a double flute starting from the cutting edges, and extending several inches up the shank of the bit, for waste removal.
The Irwin or solid-center auger bit is similar, the only difference being that one of the cutting edges has only a "vestigal flute" supporting it, which extends only about 1â„2 in (13 mm) up the shank before ending.
The diameter of auger bits for hand braces is commonly expressed by a single number, indicating the size in 16ths of an inch. For example, #4 is 4/16 or 1/4 in (6 mm), #6 is 6/16 or 3/8 in (9 mm), #9 is 9/16 in (14 mm), and #16 is 16/16 or 1 in (25 mm). Sets commonly consist of #4-16 or #4-10 bits.
