What happens if the outlet of an air operated diaphragm pump is clogged and why

Diaphragm pump is a special form of positive displacement pump. It relies on the back-and-forth agitation of a diaphragm to change the volume of the chamber to suck in and out the fluid. The air-operated diaphragm pump is mainly composed of two parts: the transmission part and the diaphragm cylinder head.

The transmission part is a driving mechanism that drives the diaphragm back and forth to agitate, and its transmission forms include mechanical transmission, hydraulic transmission and pneumatic transmission, among which hydraulic transmission is widely used. The working part of the diaphragm pump is mainly composed of a crank connecting rod mechanism, a plunger, a liquid cylinder, a diaphragm, a pump body, a suction valve and a discharge valve, among which, the driving mechanism composed of a crankshaft connecting rod, a plunger and a liquid cylinder is very similar to a reciprocating piston pump. When the diaphragm pump is working, the crank connecting rod mechanism is driven by the motor to drive the plunger to reciprocate, and the movement of the plunger passes through the working liquid in the cylinder (general...).

The outlet is blocked and will not be damaged, at most, the liquid you are transporting cannot come out, because it is blocked, after the blockage, the main valve part of the diaphragm pump will stop moving,,, but you don't have to be afraid, stop the movement will not suffocate the burner, this is a pneumatic diaphragm pump.

One of the advantages of this is that this is used in sewage treatment, filter presses.

There are more on it.

When the outlet of the air-operated diaphragm pump is blocked, the main valve part of the diaphragm pump will stop moving, but it will not cause damage to the pump. When the liquid conveyed by the diaphragm pump cannot come out, the transfer process is blocked and the liquid may accumulate on the outlet side of the pump. In this case, the operator can increase the compressed air pressure or adjust the outlet valve to increase the output flow.

If none of these methods solve the problem, the operator can seek the help of a professional to determine further treatment.

There are also several types of pneumatic diaphragm pumps, if the outlet liquid pressure and air pressure are equal, that is, 1:1, the outlet blockage will make the pump slowly stop. The reason is the pressure balance, if it is a motor pump, the outlet is blocked, and the motor will be overloaded and burned out by continuous work.

What brand of pneumatic pump do you use! The outlet is clogged, is that outlet check valve okay? I can do pneumatic pump repairs to spare parts! Please contact us if necessary!

It is mainly judged and distinguished by the following points.

1. Appearance, the appearance of the imported pneumatic pump is very good, and the painting will be relatively uniform and natural.

2. Details, mainly some small screws, through the screw material, the imported pneumatic pump will choose a better material, you can also look at the screw manufacturer.

3. Whether it is found on the pump body made in, now it is imitated in more and more imported brands to set up factories in China, according to national laws, products manufactured in China should be clearly marked as made in China.

Such as Ingersoll Rand pneumatic diaphragm pumps.

in the centrosome. There are hints on both sides.

4. Packaging, the cartons of foreign packaging are relatively thick, and the vast majority of fonts are in English.

5. This is also very important, the original imported pneumatic diaphragm pumps are relatively high, mainly due to exchange rates, tariffs, etc.

Imported pneumatic diaphragm pumps such as: Ingersoll Rand pneumatic diaphragm pumps, Graco pneumatic diaphragm pumps, Wilden pneumatic diaphragm pumps, etc., in addition to the selection of the pump body itself, the mold design itself also has a status, the design of the mold is to affect the shape, size, flow rate and so on of the QBY pneumatic pneumatic diaphragm pump. The thickness of the inner and outer walls of the pump body, as well as the design of the internal structure of the pump body, have an impact on the materials during the operation of the pump body.

In addition, the accessories of the imported pneumatic diaphragm pump, the ball seat is equipped with a round material compared with the products of domestic manufacturers, in terms of quality and durability is higher, fatigue resistance is also strong, and the service life is slightly stronger than that of domestic products, but the imported pneumatic diaphragm pump products are also much higher, but the use of domestic and foreign products and the consideration of various factors in terms of amusement, domestic pneumatic diaphragm pump products have a higher cost performance, after all, there are innate advantages in the first aspect. After all, more and more pneumatic pneumatic diaphragm pumps are used, and the gap between our domestic pneumatic diaphragm pump products and imported products is also narrowing.

The above is a brief description of the difference between imported pneumatic diaphragm pump and domestic pneumatic diaphragm pump, users can choose the more suitable air-operated diaphragm pump according to their own needs and their differences.

The inlet and outlet of the air-operated diaphragm pump can be distinguished by the following methods:

Identification: The inlet and outlet of the air-operated diaphragm pump are usually marked on the pump body, and there are generally"in"or"out"or arrows to distinguish between them.

Diameter size: The diameter of the inlet and outlet of the pneumatic diaphragm pump is usually not the same as the megabase, and the inlet is generally larger than the outlet.

Visual inspection: The inlet and outlet are usually located differently and can be distinguished by visual inspection, generally the inlet will be connected to the material storage tank or container, and the outlet will be connected to the conveying pipe.

Flow direction: The flow direction of the inlet and outlet of the pneumatic diaphragm pump is also different, the inlet is usually the direction of the inhaled material, and the outlet is the direction of the discharged material.

It should be noted that when installing and using an air-operated diaphragm pump, it is necessary to ensure that the inlet and outlet connections are correct, otherwise it will affect the working efficiency and life of the pump. When carrying out repairs and replacing parts, it is also necessary to pay attention to the distinction between inlet and outlet to avoid incorrect operation.

Insufficient air pressure: Insufficient air supply pressure will cause the air-operated diaphragm pump to stop working. Check whether the compressed air pressure meets the requirements.

Insufficient liquid level: If the liquid level is insufficient, the air-operated diaphragm pump may stop operating. Check that the liquid level is sufficient, if it is insufficient, it needs to be filled with liquid in time.

Clogged filter of air-operated diaphragm pump: If the filter of air-operated diaphragm pump is clogged, it will cause the air-operated diaphragm pump to stop operating. Cleaning or replacing the filter can solve this problem.

Diaphragm rupture: If the diaphragm of an air-operated diaphragm pump ruptures, it will cause the pump to stop. The diaphragm needs to be replaced.

Pump body damage: If the pump body of an air-operated diaphragm pump is damaged, it can also cause the pump to stop. The pump body needs to be replaced.

Blocked air ducts: If the air ducts are blocked, the air-operated diaphragm pump will also stop working. Check the pipes for blockages, clean or replace them.

Liquid viscosity is too high: If the liquid viscosity is too high, it will cause the air-operated diaphragm pump to stop. The liquid needs to be replaced or the pump's parameters adjusted.

There are several reasons why an air-operated diaphragm pump may stop working:

1.Air source problem: Pneumatic diaphragm pumps need a stable air source**, if the air source pressure is insufficient or the air source pipe is blocked, it will cause the pump to not work properly.

2.Blockage of the pump body: Blockages may occur inside the pump body, such as the filter at the inlet of the pump body is clogged with dirt, or the diaphragm inside the pump body is stuck with dirt.

3.Pump leakage: The diaphragm or seal inside the pump body is damaged or aged, resulting in air leakage and failure to work properly.

4.Solenoid valve failure: The control solenoid valve of the pneumatic diaphragm pump is faulty, and the switch of the air source cannot be controlled, resulting in the pump not working normally.

5.Power supply issues: If the air-operated diaphragm pump is controlled using a solenoid valve, then power supply issues can also cause the pump to not work properly, such as a faulty power line or an unstable supply voltage.

Abstract:The air-operated double diaphragm pump sometimes has the phenomenon of not working only outgasing, and the reasons for this phenomenon are various, and the user needs to check whether there is any abnormality in the sealing gasket, diaphragm, air piston, Hongchang stupid gas valve and other components. During the use of the pneumatic diaphragm pump, it is necessary to pay attention to fastening the pump and the connecting pipe joints to prevent the split pump from generating electrostatic sparks due to vibration and impact; Maintain good exhaust and ventilation, keep away from flammable, explosive and heat sources, etc.

Let's take a look at the reasons why the pneumatic double diaphragm pump does not work and only emits gas, as well as the precautions for the use of the pneumatic diaphragm pump. 1. What happens when the pneumatic double diaphragm pump does not work and only emits gas.

Why does the air-operated double diaphragm pump not work and only discharges gas? In fact, this is an obvious fault phenomenon, the operator should check the cause of the abnormal situation in time, and the manufacturer recommends checking whether the sealing gasket, diaphragm, air piston, outlet valve and other parts are abnormal, and repair or replace new accessories as needed.

There are many reasons why the pneumatic double diaphragm pump does not work and only emits gas, and there are certain differences in the composition of internal parts of different types of products, but on the whole, the method of checking the fault is the same

1. Remove the outlet valve and use lubricating oil to ensure its normal operation;

2. Check whether the gasket is damaged, and replace it immediately if so;

3. Check the diaphragm of the diaphragm pump, and replace it in time if it is damaged;

4. Check whether the ventilation piston is faulty, if it is stuck or other operation problems, you can use a thin antifreeze lubricant;

5. Check whether the filter screen at the air inlet end is blocked by impurities, clean it in time if there is, and replace it in time if it is damaged.

On the whole, when the pneumatic double diaphragm pump does not work and only emits air, it is necessary to disassemble the pump and check all kinds of vulnerable and clogged parts, which can usually quickly find and solve the problem.

2. Precautions for the use of air-operated diaphragm pumps.

The air-operated diaphragm pump is a positive displacement pump powered by compressed air and the volume change caused by the reciprocating deformation of the diaphragm, and its working principle is similar to that of a piston pump. The pneumatic diaphragm pump is used in accordance with certain principles and methods, and is used in accordance with certain instructions and precautions in the specific operating procedures, which can produce important use effects and contributions, and play a good role in use.

The following points should be paid attention to when operating with an air-operated diaphragm pump:

1. Ensure that the maximum particles contained in the fluid do not exceed the maximum safe particle diameter standard of the pump;

2. Tighten the pump and the connecting pipe joints to prevent the split pump from generating electrostatic sparks due to vibration impact;

3. Use antistatic hoses. The reliability of the grounding system should be checked and tested periodically, and the grounding resistance should be less than 100 ohms;

4. Keep good exhaust and ventilation, away from flammable, explosive and heat sources;

5. The inlet pressure should not exceed the maximum allowable pressure of the pump, and the compressed air higher than the rated pressure of the pipeline pump may lead to personal injury and property loss and damage to the performance of the pump.
