Application In
The following points for installation of solenoid valve are as
follows:
1, installation should pay attention to the arrow on the valve body
should be consistent with the media flow direction. Do not install
in places where there is direct drip or splash. Solenoid valves
should be installed vertically.
2, solenoid valves should be guaranteed to operate normally within
the 15%-10% range of the rated voltage.
3. After installing the solenoid valve, there should be no reverse
pressure difference in the pipeline. It needs to be energized
several times to make it warm enough to be put into operation.
4. Solenoid valve should be thoroughly cleaned before installation.
The medium should be free of impurities. Filter before valve.
5, when the solenoid valve malfunctions or cleaning, to ensure that
the system continues to operate, it should install bypass devices.
Working principle
There is a close cavity in the solenoid valve, and there are
through holes in different positions. Each hole leads to different
tubing. There are valves in the middle of the cavity and two
electromagnets on both sides. Hydraulic oil enters different drain
pipes and then pushes the piston of the cylinder through the
pressure of the oil. The piston then drives the piston rod, which
drives the mechanical device. In this way, the mechanical movement
is controlled by controlling the current of the electromagnet.
Daily maintenance of pneumatic solenoid valve:
1. Disassemble and clean the internal impurities of the pneumatic
solenoid valve regularly, check whether each part of the pneumatic
solenoid valve is seriously worn, and consider replacing or
repairing the damaged parts according to the actual situation.
2. When disassembling the pneumatic solenoid valve, the power
should be cut off and other supporting facilities should be closed
first, and pay attention to the installation sequence of each part
of the solenoid valve in the disassembly process.
3, pneumatic solenoid valve prone to failure problems are mainly
vulnerable parts such as coils and seals, coils burned out is due
to overload work, the seals themselves are vulnerable parts, mostly
due to natural wear and tear in a long time of work.
4, when the pneumatic solenoid valve at work, if often vibration,
it is easy to cause damage to the pneumatic solenoid valve parts,
so the maintenance of the solenoid valve, but also to ensure the
stability of the working environment, fixed the pneumatic solenoid
valve parts regularly, such as nuts and bolts.
5. If the working environment of the pneumatic solenoid valve is
open air, it may cause the rust of the pneumatic solenoid valve and
parts and make the solenoid valve unable to work normally. So the
need for maintenance, to ensure the stability of the performance of
the operation.
6. If the pneumatic solenoid valve is important in the workplace,
it shall be equipped with special maintenance personnel to ensure
the working stability and low failure rate of the solenoid valve.
This will make it more efficient, cost less to maintain and last
longer. Pneumatic solenoid valve maintenance method, and the
general class valve method is mostly similar, in the actual use and
maintenance process, users can refer to the relevant instructions
for appropriate maintenance and maintenance operation. This for
pneumatic solenoid valve and other valve life extension has a
positive effect.
