First, the solenoid valve does not work after being energized
Check if the power wiring is defective → rewire and connector connection
Check if the power supply voltage is within the ± working range - → adjust the normal position range
Whether the coil is desoldered → re-welded
Short circuit of coil → change coil
Is the working pressure difference inappropriate → adjust the differential pressure → or replace the proportional solenoid valve
Fluid temperature is too high → replace the proportional solenoid valve
There are impurities that cause the main valve core and moving iron core of the solenoid valve to be stuck → for cleaning. If there is seal damage, replace the seal and install the filter.
The viscosity of the liquid is too high, the frequency is too high and the life is up to → replace the product
Second, the solenoid valve can not be closed
The seal of the main spool or the iron core has been damaged → replace the seal
Whether the fluid temperature and viscosity are too high → replace the solenoid valve of the opposite port
There are impurities entering the solenoid valve to produce the valve core or moving iron core → cleaning
Spring life has reached or deformed → replaced
The orifice balance hole is blocked → timely cleaning
The operating frequency is too high or the life is up to → re-elect or update the product
Third, other circumstances
Internal leak → check if the seal is damaged and the spring is not properly assembled
External leakage → loose connection or seal is broken → tighten the screw or replace the seal
There is noise when energized → the solid parts on the head are loose and tightened. The voltage fluctuation is not within the allowable range and the voltage is adjusted. The iron core suction surface is dirty or uneven, and it is cleaned or replaced in time.
PVC High Speed Door are designed for indoor use and ensure rapid handling operations between different areas that should remain separated. These safe and efficient industrial doors are made of a shaped steel frame and covered with PVC. These high speed doors are safe and efficient and consist of a shaped steel frame covered with PVC. Safety is ensured by their photocells and barriers.
High speed doors protect us from harm, save energy and help us to separate processes for optimal productivity. A high speed door's most important job is to simply open and close quickly and safely every time you need it.
The high speed pvc roll shutter door require high strains, caused by the high operating speed and the frequency of openings, have to be taken into account during construction. In the same way, basic conditions like size and installation location add up to considerable requirements regarding safety and control technique.
