Valve Failure of the Concrete Mixing Station

(1) cannot change or reverse the action to slow. Should first check whether the work lubricator normal; lubricating oil viscosity is appropriate. When necessary small concrete batching plant, replace the lubricating oil, clean the sliding part of the valve or replace the spring and reversing valve.Henan Daswell Machinery Co., Ltd,is a professional manufacturer and trader specializing in the research, development and production of construction machinery for nearly 30 years. Our main products are as follows:diesel concrete mixer,concrete batching plants,concrete mixer,blocking making machine,concrete pump,etc. (2) valve core sealing ring wear, valve and valve seat damage, gas leakage, slow or normal operation can not change, should replace the sealing ring, the valve core and valve seat, when necessary, replace the new valve. (3) pilot solenoid valve inlet and exhaust holes are blocked by sludge and other debris, not tightly closed, the movable valve core is clamped and the circuit fault, which can lead to the valve does not change. Should the impurity timely cleaning of solenoid valve and pilot valve core on the sludge activity. Check circuit fault before, should be the first to turn the valve of the manual knob to turn a few times, at the rated pressure of the valve is able to change the normal, if the normal commutation, it is a circuit fault. Check the voltage of the solenoid coil to see if the voltage is reached, if the voltage is too low, the control circuit should be further examined in the power supply and the associated travel switch circuit. If the rated voltage of the valve can not be normal batch plant for sale, the solenoid coil should be checked to check whether the joint (plug) is loose or contact is not real. Method is to pull the plug concrete batch mix plant, the coil resistance measurement value (in general should be a few hundred to several thousand ohms), if the resistance is too large or too small, indicating that the electromagnetic coil is...
