How do you get hard concrete out of a hose?
You can also blow out hard concrete out of pipe with a pressure cleaner hooked to a blow out cap. Hang the pipe vertically with a forklift and turn it on. Make sure you blow out cap is a Billy bad ass because it will blow.
How do you clean a concrete boom pump?
Wash the hopper and stick the concrete pump cleaning sponge ball in the reducer. Fill the hopper full of water to push the cleaning sponge down the system, cleaning all the hoses. Make sure to use a sponge ball one size bigger than the hose. For example use a 4″ ball for a 3″ hose.
How do you maintain a concrete pump?
CONCRETE PUMP MAINTENANCE CHECKLIST
- Grease the back end of the pump.
- Check the oil.
- Inspect the pretension on the gas of the accumulator.
- Check the wash-box for grout and dump the water.
- Replace any blown fuses.
- Check the truck diesel, oil, power steering fluid, radiator fluid and tires.
How do you prime a concrete pump?
You are going to use about half a bag of fire clay per mix. Fill your bucket half way with water, then add some fire clay and give it a good mix. Keep on adding fire clay to the water and mixing until the consistency is between pancake batter and chocolate milk. Add clay and water until you get that consistency.
What will dissolve concrete?
Concrete is a durable building material that takes special materials to dissolve once it’s hardened into place. Phosphoric acid and trisodium phosphate are the main compounds used to dissolve concrete leftover from masonry work.
What dissolves concrete not PVC?
Acid. It is also possible to dissolve concrete with acid, allowing the substance to soften and allow the backed-up water and debris to start to flow through. Pour hydrochloric acid (sometimes also known as muriatic acid) into the clogged drain and leaving it for between two and three hours.
What is a concrete line pump?
A concrete line pump is a long hose attached to a stationary pump mounted on a trailer. This hose allows you to more easily direct the concrete pour and is great for horizontal pumping, as you can extend the hose virtually as long as you need it.
How does a concrete pump work?
A concrete pump works by using a valve system and the basic principles of hydraulics. After a mixing truck pours liquid concrete into a hopper, the concrete pump sucks the liquid concrete through a valve system and into the area where it needs to be laid down.
Why should the water box covers always be installed when the pump is in operation?
TO PREVENT SERIOUS INJURY, NEVER REACH INTO THE VALVE OR THE WATER BOX. The water box covers must be in place when the machine is in operation. When removed, the transmission must be out of gear and the accumulator bled to zero pressure.
Why do you have to prime a concrete pump?
Concrete pumping works because when pressure is applied to concrete in a pipe, the finest material of cement and water are forced to the pipe wall, making a slippery layer for the concrete in the pipe to slide on. When you prime, the slippery material is already present in the pipe before concrete hits it.
How do you lubricate concrete when pumping?
For successful pumping, aggregate must have a full coating of cement grout to lubricate the mix as it is being pumped. A delay in placing the concrete due to traffic or job site problems, as well as hot weather conditions, may cause the concrete to begin to set prematurely.
What happens when a concrete pump hose gets kinked?
Premature localized wear of the hose, and eventual rupture of the hose, may also occur at the point where the hose is kinked. Locating a Blockage Concrete pumping crews and the concrete pumper must be constantly aware of the possibility of a pump line blockage or rock jam, and be able to remove it promptly and safely.
What to do if your concrete pump line is blocked?
Locating a Blockage Concrete pumping crews and the concrete pumper must be constantly aware of the possibility of a pump line blockage or rock jam, and be able to remove it promptly and safely.
What should be considered when designing a concrete pumping system?
The entire pumping system must be evaluated for the job it is to perform. Considerations include a properly sized system including pump capacity and motor horsepower to move the concrete through the full length of the pipeline.
