In essence, pneumatic
diaphragm pump belongs to embolic pump, also known as control pump. There are
four main combinations of it, which you can choose according to your personal
needs.
Low flow
When you are faced with the problem of small flow of QBY
pneumatic diaphragm pump, it is suggested that you consider these factors.
First, check whether the inlet and outlet check valves of the diaphragm pump
have been slightly worn. If the wear is serious, you must replace it in time.
Otherwise, it will affect the normal operation of the diaphragm pump. Moreover,
we need to check whether the inlet and outlet check valves are stuck by large
particles. If it is stuck by large particles, the diaphragm pump will encounter
certain difficulties in the process of suction, and discharge will also be
abnormal to a certain extent. After finding the cause, we must solve it
immediately to prevent affecting the work process and causing damage to
interests.
There is no pressure at the outlet
Why is there no pressure at
the outlet of the diaphragm pump? First, check whether the silencer of the
diaphragm pump is blocked. If there is blockage, there is no way to discharge a
large amount of gas in the diaphragm pump in a short time. In this way, the
pumping speed is seriously affected, the speed is greatly slowed down, and there
will be no pressure at the inlet and outlet. Second, it is recommended to check
the upper and lower covers of the valve to determine whether the valve cover has
air leakage or damage due to the impact of the valve core. Third, I hope you can
pay attention to the inside of the pump. There is a central shaft inside the
pump, and the central shaft has four sealing rings. If these four sealing rings
are damaged, there will also be no pressure at the outlet of the diaphragm
pump.
To sum up, this is the analysis of common problems of stainless steel
diaphragm pump that Xiaobian will introduce to you today. In fact, to be honest,
in addition to the above two problems, the diaphragm pump may sometimes not
work.
