1, the proportion of liquid is too large, or the concentration is too large, the suction of the pump can not reach, so in this case, the pump is working, but the liquid can not be played;

2, the valve ball and ball seat in the pump body are not well sealed, and the liquid is immediately returned back, in this case, the pump body is a liquid, but the flow is very small, and the head is very low;

3, the inlet pipe seal is not good, in this case, the pump is normal work, but because the liquid can not suck, so the pump can not play the liquid;

4, the air source pressure of the air intake is not enough, the air source pressure range of the domestic pneumatic diaphragm pump is generally 2-7kg, greater than or less than this value, the pump can not work normally;

5, pneumatic diaphragm pump pump body wearing parts, in this case is easier to solve, replace the wearing parts can;

6, the lowest mistake is to connect the import and export of the pump backwards, the pump is the import under, the export on. The probability of such a mistake is very small, but I have met such clients;

7, the origin of the air compressor is too low will be insufficient gas (normal pressure is 5-7 kg);

The quality of diaphragm pump mainly includes the requirements of structural stability, durability, sealing and operation effect. First of all, the structure of the diaphragm pump must be stable and strong, able to withstand high pressure and complex working environments. This requires aodd pump‘s main components to be made of high-strength and corrosion-resistant materials, with precision machining and rigorous assembly processes. At the same time, the connecting part of the diaphragm pump should have good sealing to prevent cross-contamination of the medium inside and outside the pump.

Secondly, the durability of the diaphragm pump is one of the important indicators to test its quality. Diaphragm pumps usually need to run for a long time, so its parts and seals must have a long service life. This involves the choice of materials, the impact of external environmental factors on the pump, and the correct maintenance and maintenance. Only by ensuring that the diaphragm pump has sufficient durability can it meet the needs of industrial production.

In addition, the sealing of saiken’s diaphragm pumps is also an important indicator of their quality. The diaphragm pump must be able to effectively prevent the medium from leaking or gas entering the pump body during the working process, so as to ensure the stability and safety of fluid transmission. In order to achieve a good sealing effect, diaphragm pumps usually use reliable sealing structures and technologies, such as double-layer diaphragms, sealing rings, etc. These measures not only ensure the normal operation of the diaphragm pump, but also reduce the failure rate and maintenance costs of the pump body.

In short, diaphragm pump, as an important fluid transmission equipment, plays a vital role in industrial production. In order to ensure the efficient, stable and safe operation of the diaphragm pump, higher requirements are put forward for its quality. Only with a stable structure, durable life, good sealing and operation effect, diaphragm pumps can meet the needs of various industries, and provide reliable support for the development of industrial production. With the continuous progress of technology and the intensification of market competition, diaphragm pump manufacturers need to continuously improve product quality and improve technical level to meet the increasing requirements of customers.
