Fix The Failure Of The Valve Tester
Valve testing machine in the use of the process of frequent failure, so how to fix these failings? Have a look below.
1, check the insulation resistance of the valve tester. Usage 500v insulation resistance meter examination, the insulation resistance needs to not be less than 5 m Ω, if less than this worth, ought to open up the drainpipe as well as vent hole, or drying after usage.
2, examine the valve grinding device air vent, water hole, oil opening as well as cable television joint sealing hangs, if there hangs must be screwed limited.
3, various sorts of valve testing machines, must be used according to the specified head, matching steel pipe, rubber pipe or sail pipeline diameter need to fulfill the technological demands.
4, the valve test machine wire had far better not have a joint, if the joint should be wrapped, the whole cord should not be harmed, broken phenomenon, or should be replaced by a new cord. Also, the wires must be overhead and also not as well long.
5, before starting up the valve screening machine, make a detailed evaluation of the power supply lines as well as buttons and also run idle for 3 ~ 5min on the ground. If the device runs normally, placed it right into the water and also placed it right into usage.
6, the valve examination electromechanical resource need to be selected in accordance with the stipulations, the range in between the power supply as well as the water pump ought to not be too far, the voltage must be within 10% of the regular value, as well as buried in the power supply or the water pump a 1m above the iron bar as a ground cord, to guarantee safety and security. The power supply should be connected to the ground dependably, add a leak guard. Furthermore, try to avoid the power supply voltage is too expensive or too low when the boot, the voltage is expensive, will cause the electric motor to get too hot as well as stress out the winding.
