Always apply a small amount of oil to the outer surface of the concrete pool before starting to work so that the concrete does not stick to it while working. Be careful not to let the oil get into the concrete pool because it will spoil the concrete. For this purpose, use an oil that does not have an erosion effect on plastic and rubber parts.
Water box or water tank of concrete injection jacks is full of water.
Use a stirrer or vibrator. Pour the buttermilk into the concrete basin. Buttermilk contains two units of cement, one unit of sand and one unit of water. The amount of buttermilk depends on the length of the pipes. For short routes or when the conditions are ready for concreting, the use of cement and water slurry is sufficient.
Before the slurry is completely emptied from the concrete pool, the concrete must be emptied for pumping in the concrete pool.
Do not start pumping with the maximum impact and slowly increase the number of impacts after some concrete exits from the concrete discharge pipe.
Never use the pump when the concrete pool is empty. Because it causes erosion of the piston and seals. Water should be used for testing, service and cleaning.
When the concrete pump is suspended, especially in tropical regions, prevent the concrete from hardening by moving the concrete back and forth in the pipes.
During the work, try not to leave the concrete basin empty.
Getting lol
When the tube is taken, the pressure inside it reaches the maximum. Therefore, you should not bend the flexi-bell pipe too much or put its head into the concrete. . If the blockage of the pipe is not resolved, turn it off a few times, turn off the device, drain the hydraulic pressure of the gas tank or accumulator, and then try to open the blocked pipes. Always remember that if the inside of the pipes is clean, the pipes will catch less.
Pipe cleaning after finishing
First, completely drain the cylinder pipe and the concrete pool. Then clean the inside of the pipes. The best way to clean the pipes is to use a sponge ball or wash with water.
Never use salt water for washing. >
Using wind for washing is dangerous and should be done by qualified personnel.
After washing the pipes, the concrete inside the injection cylinder and the concrete pool should be drained and washed completely. The cylinder must be cleaned of any concrete.
After concreting, especially in cold areas, the water tank and water inside the water pump and the box behind the injection cylinder should be drained to prevent water from freezing in them.
Gas storage test method (acomeulator)
For a short time, the engine should be on and the device engaged. At first, the needle moves slowly towards zero and then it suddenly reaches zero.
An emergency method to set up a mast
In cases where the hydraulic pump of the rig is damaged, Shuying has made it possible to use two hoses and a device or device that has a hydraulic pump with the specifications of the rig's hydraulic pump to repair the jacks of the rig, base and control and start the tools.
There are two blind pipes on the sides of the control valve of the tools. The blinded pipe with a red cap located behind the servo filter is intended to supply the pressure line from another device and the blinded pipe with a blue blinder under the control valve is intended to connect the oil return path from the control valve to the tank of the pressure supplying device. is
