A pump is a machine that conveys liquids or pressurizes liquids. It transmits the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid, and is mainly used to convey various liquids including water, oil, acid and alkali liquids. With the innovation of industrial technology, there are more and more kinds of pumps. Today we would like to introduce the product is diaphragm pump, which is a kind of equipment that protects the live column and the pump cylinder by separating the liquid to be transported from the live column and the pump cylinder with the help of a membrane.
·Can diaphragm pumps pump air?
·What is the working principle of diaphragm pumps?
·Operating precautions for diaphragm pumps.
From the principle, the diaphragm pump is able to extract air. It is reported that the import and export valves of pneumatic diaphragm pumps work alternately on and off, the valve ball and the valve seat between the constant friction, when extracting liquid, the material plays the role of lubricant and coolant, indirectly extending the life of the valve. Also, in order to form a vacuum and draw liquid, the liquid film needs to be formed between the valve ball and the valve seat in order to achieve the design effectiveness. In short, the use of diaphragm pumps to extract gas can form a certain vacuum, but long-term use will certainly affect the life of the.
When the diaphragm pump is working, the crank linkage mechanism is driven by the motor, driving the plunger for reciprocating motion, the movement of the plunger through the working fluid in the cylinder and to the diaphragm, so that the diaphragm back and forth drumming.
Compressed air from the pump inlet into the air distribution valve, through the air distribution mechanism to introduce compressed air into one of the cavities, pushing the diaphragm movement in the cavity, while the other cavity in the gas discharge. Once the end of the stroke is reached, the air distribution mechanism automatically introduces compressed air into the other working chamber, pushing the diaphragm in the opposite direction, so that the two diaphragms continuously and synchronously reciprocating movement.
Ensure that the maximum particles contained in the fluid do not exceed the maximum safe passing particle diameter standard for the pump. In addition, the inlet pressure should not exceed the maximum allowable pressure of the pump. Compressed air above the rated pressure may cause personal injury and property damage and damage the performance of the pump.
Diaphragm pumps are driven by inverter motor, if the open and close load is too large or too small, short time load fluctuations, long-term operation under low load, etc. have an impact on the inverter. In order to avoid equipment failure as much as possible, the on/off load is rigidly controlled at about 30% and set in the instrument so that the increase and decrease of load must be completed within a period of time.
Diaphragm pumps need to be well grounded. Because electrostatic sparks may cause an explosion resulting in personal injury or death and property damage, use a large enough cross-sectional area of wire as needed to ground the pump properly and reliably with the grounding screw.
With the above information, do you have a further understanding of diaphragm pumps? Diaphragm pump is a more special form of displacement pump. It relies on a diaphragm to drum back and forth to change the volume of the studio to suck in and discharge the liquid. Our stainless steel diaphragm pumps have many advantages, such as high efficiency, compact design, durability, etc. If you need to know more information about diaphragm pumps, please pay attention to our company.
