During the communication between Holian’s customer service staff and some small oxygen concentrator repair shops, or even individual users with strong hands-on abilities, it was found that many problems were basic installation problems. Here are some common problems summarized.
Before construction, please refer to the user manual to check whether it meets the usage requirements. If the models and brands don’t match, communicate with the manufacturer in time and return the products to the factory. For example, if you purchased a common solenoid valve but a pneumatic one-way solenoid valve was delivered, then you should communicate with the manufacturer immediately for an exchange.
Before using the pipeline, you must clean the pipeline first. For unclean materials, a filter should be installed to prevent the valve from clogging.
For solenoid valves that have been shut down for a long time, they need to be cleaned and cooled before use. Solenoid valves like air conditioning solenoid valves are extremely prone to dust accumulation or damage. When disassembling, arrange the parts in order and then assemble them.
Solenoid valves generally operate in one direction and cannot be inverted. There is an arrow on the top of the valve indicating the flow rate direction of the fluid in the pipeline.
When the machine is shut down, except for products such as high-temperature normally open solenoid valves, heating or insulation measures must be taken for solenoid valves.
Solenoid valves are usually installed on the general oil circuit board with the electromagnetic coil facing vertically upward. Some products can be assembled at will, but if conditions permit, it is recommended to use the vertical installation method to extend the service life. For some special products like solenoid valve manifold plates, special attention should be paid to their particularities during assembly.
After connecting the magnet winding wire (RF connector), check whether the connection part is loose. If it is loose, it will cause the piston-type normally open solenoid valve to malfunction. To ensure continuous production, a bypass should be set up for convenient maintenance without affecting production.
Before using the one-way solenoid valve, you need to understand the usage environment first and then make a purchase. Since there are seven common problems in the assembly of the one-way solenoid valve, installers must be extra careful to avoid accidents.
