A hydraulic ductile iron pipe fitting cement mortar lining coating machine

Abstract

The invention discloses a hydraulic coating machine for a cement mortar lining of a spheroidal graphite cast iron pipe fitting. The hydraulic coating machine for the cement mortar lining of the spheroidal graphite cast iron pipe fitting comprises a frame component, a power box component, an extrusion head component, a feed system, a vertical shaft, a rotary working platform, lifting oil cylinders and a hydraulic pumping station, wherein the frame component is a rectangular steel framework formed by welding four upright posts and cross beams; the rectangular steel framework is provided with two guide rails; the power box component is provided, on a speed changing system, with a motor and a lubrication system; the lower part of the speed changing system is provided with a coupling; the extrusion head component is connected with a driving shaft of the power box component; a guiding mechanism is arranged on the guide rails; the lifting oil cylinders are arranged at the right part of the power box component; the vertical shaft is arranged at the left part of the frame component; the feed system is arranged at the right part of the frame component. By using the hydraulic coating machine for the cement mortar lining of the spheroidal graphite cast iron pipe fitting, the lining is good in flatness, is improved in degree of finish, improved in water delivery coefficient and reduced in bulging; the hydraulic coating machine for the cement mortar lining of the spheroidal graphite cast iron pipe fitting is applied to the technical field of the hydraulic coating of cement mortar linings of spheroidal graphite cast iron pipe fittings.

Description

technical field [0001] The invention relates to a hydraulic cement mortar lining coating machine for ductile iron pipe fittings in the technical field of hydraulic coating of cement mortar linings for cast iron pipe fittings, and is especially suitable for nodular cast iron pipe fittings such as elbows, straight pipes and tees. Hydraulic application of cement mortar lining of cast iron pipe fittings. Background technique [0002] At present, ductile iron pipe fittings used for pressure are in accordance with ISO2531; 2009 international standards and GB / T13295-2013 national standards. The inner wall of ductile iron pipe fittings must be coated with a certain thickness of cement mortar lining, according to ISO4179:2005 regulations, according to different specifications , The thickness of the lining is 3-12 mm, and its functions are: 1. Anticorrosion of pipe fittings; 2. Preventing drinking water pollution; 3. The smooth surface of the lining is conducive to improving the water...

AI Technical Summary

Problems solved by technology

Lining flatness, poor finish, affect water transfer coefficient

During the operation of the water pipeline, once the cement mortar lining falls off, it will not only cause water pollution, but in severe cases, the cement mortar lining that falls off will block the valve, causing the entire water pipeline to fail to work normally.
