Use, maintenance and common fault treatment of grouting machine
Use, maintenance and common fault treatment of grouting machine
Use of (I) grouting machine
(1) The operator must be trained and qualified before operating the grouting machine, without training or non-operating driversDo not operate the grouting machine.
(2) During grouting operation, operators must wear goggles. If corrosive chemical slurry is injected, alsoWear protective equipment to prevent skin damage.
(3) In order to ensure smooth work, the machine must be tested before grouting:
① Check whether the hydraulic oil in the oil tank is sufficient.If the surface is too low, it should be added in time;
Check the motor and oil pump, should be able to easily turn a few turns;
③ Open the pressure gaugeTurn off and open, and check whether the pressure gauge is normal;
④ Put clean water into the test machine and check whether the rotation direction of the motor is correct.
(4) After the test machine is normal, normal grouting shall be carried out; in order to protect the grouting cylinder and its sealing performance, cement slurryFiltration should be carried out first, and the steel wire strainer should be wrapped in the pulp inlet for re-filtration.
(5) During grouting operation, attention should be paid to prevent pipe blockage.
(6) After operation, the grouting pipe joint must be removed, washed with clean water for more than 3min, and the pump and pipe must be cleaned.Residual slurry in the channel to prevent residual slurry from solidifying.
(7) electrical control box and other electrical appliances must be kept dry, not drenched, often check the wire jacket, to preventLeakage due to breakage.
(8) The grouting pump shall be placed horizontally, and the joint of grouting pipe shall be firm without leakage.
(9) Do not have big bumps during mechanical handling, and do not knock on all parts of the machine at will.
(II) maintenance and common fault handling
1. Routine maintenance
(1) The grouting machine has been used for a long time, and the line is easy to age. Whether the contact of each line of the electric control system is firm,Do a comprehensive inspection for leakage.
(2) check the grouting machine oil tank filter, oil filter, and cleaning, regular replacement of hydraulic oil, builtAbout a month to replace the hydraulic oil.
(3) Check whether the connection and fastening of each hydraulic joint of the grouting machine are correct and reliable to prevent the connection of each componentLoose, resulting in inefficiency and safety hazards.
(4) Start the grouting machine for a short time and listen carefully to the sound of the machine so as to grasp whether the rotation situation isGood.
(5) If the machine is out of service recently, the inlet and outlet valves and working cylinders should be disassembled, cleaned and brushed to prevent rust.Liquid or grease, and then assembled for standby.
(6) When disassembling the inlet and outlet valves and working cylinders of the grouting machine, first remove the inlet and outlet valves and remove the screw at the end of the working cylinder.Remove the two nuts of the cylinder head and cylinder barrel. Please do not damage the seals during disassembly.
2. Common fault handling
(1) The grouting pump does not absorb water.
Cause: Insufficient pouring water diversion, air in the pump cannot be discharged, air leakage in the suction pipe, and between the front lining plate and the impeller.The gap is large.
Treatment method: continuously pour water diversion, reflect on whether the pipeline leaks, and adjust the gap between the impeller and the front lining plate.
(2) The grouting pump feeds water slowly.
Reason: The gap between the front lining plate and the impeller is large, and the water outlet pipe cannot discharge all the air.
Treatment method: adjust the gap, regulate the water outlet pipe, and vacuum installation of the device.
(3) grouting pump water pressure is small, small flow.
Reason: there is air in the pump, the gap between the impeller and the front liner is large, the separation and gathering device is not tightly closed, the impeller orLiners worn.
Treatment method: empty the gas in the pump, adjust the gap, adjust the gap of the friction plate of the separator, and replace it.Impeller or liner.
