mixing valve failure

Valve failure are: valve can not commutation or commutation slow, gas leaks, solenoid pilot valve is faulty and so on.
(1) valve commutation or commutation can not slow, usually due to poor lubrication, the spring is stuck or damaged, oil or impurities stuck sliding parts and other causes. In this regard, you should first check the lubricator is working properly; lubricant viscosity is appropriate. If necessary, replace the oil, clean the sliding valve parts, or replace the springs and valve.
(2) after prolonged usage valve steel cement silo  prone to wear and tear, stem and seat damage phenomena, leading to gas leakage inside the valve, the valve motion is slow or does not change to the other failures. At this point, you should replace the seals, stem and seat, or valve replaced.
(3) If the solenoid pilot valve inlet, sludge and other vent is clogged, closed lax plunger is stuck, circuit failure, can lead to valve can not be normal commutation. Wheel Loader three cases should be cleaned on the core activities of the pilot valve and the sludge and impurities. The circuit failures are generally divided into the solenoid control circuit faults and fault types. After checking circuit fault, should first manual valve knob a few turns to see the rated pressure valve is working correctly for commutation, if normal commutation, then the circuit is faulty. Inspection, the available instrument measuring the voltage of the solenoid, to see whether the rated voltage, if the voltage is too low, should further examine the power control circuit and the associated limit switch circuit.

mixing station failure

Valve failure are: pressure regulator is not high, or the slow pressure rise.
Pressure regulator is not high, often due to pressure regulator spring break or diaphragm failure and must be renewed; pressure rises slowly, usually caused because the filter is clogged, should be removed and washed.
Piping failures are: leaking pipe joints, hose rupture, condensate aggregation.
Leaking pipe joints and hose rupture up to judge the sound leak from the site, should be promptly repaired or replaced; if there is accumulating condensate pipeline, it shall promptly drained, is characterized by condensed water in the northern winter, easy to knot Ice and clogging gas.
Compressed air processing components (triplets) faults are: oil and water separator failure, regulator and lubricator failure.
Wheel Loader oil-water separator is divided into, filter clogging, breakage, drain valve moving parts moving parts is not flexible and so on. Concrete Mixing Truck clean the filter, remove sewage and impurities inside the oil.
Regulator fault with the "valve failure" identical.
Lubricator fault phenomenon: no drop of oil deposited on the bottom of the oil cup water, oil cup seal failures. When the mist does not drip, check the inlet gas flow rate is below the fog flow, leaks, clogged fuel adjustment needle, etc.; if the oil cup bottom sediment moisture, should be immediately removed; when seal is damaged, should be replaced.

Strict control of waste discharge

Strict control of waste emissions, concrete mixer truck cleaning emissions generated by waste need to put the location of abandoned waste water to be treated in the preliminary sedimentation tank before discharge. Wheel Loader every day after work must arrange for cleaning of the site, the concrete residue eradicate station and sprinkler dust, cleaning after reported webmaster acceptance. Prohibit non-mixing stations operating room operating personnel from entering the interior kept clean and tidy. Mixing station control room personnel must be cut off after work, power and water supply, shut doors and windows, in order to ensure the safety of indoors, but also steel cement silo dust floated into the room. Mixing station after specimen production station, clean the residual concrete. Aggregate warehouse cleaning must arrange 24 hours in order to maintain warehouse clean, timely aggregate subballast to clear, warehouses often sprinkling dust. Upon completion, carefully cleaning the debris, removal of temporary construction and waste shipped to the specified location.

mixing station empty commissioning

1) Start stirring motor, two stirring shaft steering and signs should indicate the same direction. 2) vigorously fight foot pressure compressor, start discharging mechanism, discharge door opening and closing should be accurate place. 3) Start the pump to draw water, the water supply system should operate normally. 4) Wheel Loader lifting winch motor, hopper raised to unloading position, should automatically stop, Doumen open automatically. Hopper in operation, such as motor power, brake motor brake can live hopper, hopper then fell more than if 150mm, specifying the braking torque is too small, you should adjust the braking force; hopper drops, concrete mixing machine level of turnout Card live, down to the pit bottom, the rope a little loose, winch mechanism should automatically stop. 5) In the above commissioning process, if found to be not normal circumstances, you should downtime, complete troubleshooting only after the concrete mixing operation.

Powder silo mixing station set

A mixer should be set at least two cement silos, a fly ash silo, a slag silos. In order to prevent the powder inside the silo arch plugs, silo should have broken arch; mixing station site in order to improve the working environment, to cement silo breeze requirements dust, top of the silo should be automatic cleaning equipment; In order to detect cement cement silo storage capacity silo material level indicator should be set;Wheel Loader monitoring the temperature inside the silo, silos should be set within a temperature sensor; For ease of testing
samples from the silo should set up a dedicated sampling port; in order to ensure safety, lightning protection devices must be located at the top of the silo. To ensure safety, must be the foundation bearing capacity silos and steel cement silo field tests, such as bearing capacity can not meet the silos and mixers foundation bearing capacity requirements, you need to fill the foundation for change process.
