- The vane pump is one of the hydraulic pumps most interested and searched by customers today. That also proves the ability of important diversified applications of the equipment in production, processing, and assembly by hydraulic system serving the domestic industry. Today, you and the company ANH MINH LONG learn about the structure, division and application of this pump.

- You need to suck and push hydraulic fluid to supply the cylinder, the system must use a pump. Pumps have many types with different structures, sizes and designs, but the most widely used type must mention the vane pump.

- Hydraulic pump vane type is a device with the function of sucking liquid: oil, chemicals, oil ... from the tank, the source to pump push away with a certain pressure and flow to provide the actuator. cylinder action. To do so, the pump uses a separate mechanism that reduces the pressure of the liquid by alternately reducing the pressure. The pump pushes a certain amount of liquid every one rotation.

In the vane pump, the rotor part is very important. It is a circular cylindrical metal block, usually made of steel to be strong and prevent corrosion. On the rotor, there are slots for the vane to slide. The pump chamber containing the suction and push chambers is simply made but must ensure smoothness, smoothness and meticulous machining.

- Usually a pump will have a number of vane blades (flat table) ranging from 8-14 blades. The more vane number, the larger and more even pump flow. The pump operates only when the motor torque is sent to the rotor through the shaft.

=> When choosing this pump, the first thing to consider is:

+ Min pressure, max pressure: maximum pressure that a genuine vane pump can guarantee is 200 bar. If the customer uses a system that requires pressure greater than 200 bar, he is forced to choose another pump line: piston pump ...

+ High speed, minimum speed: Because speed will be related to the flow, noise of the pump while operating, pump efficiency.

Because the pump is simple in structure as well as in operation and compact, it is preferred for use in systems with small and narrow spaces.

- Types of hydraulic vane pumps.

- Vane pumps are like other hydraulic equipment with many different series and types. The accurate and objective pump classification will assist customers a lot in choosing the pump and using the pump to bring high efficiency.

- It is based on the structure and operating characteristics that divided into single vane pump and dual vane pump.

- Advantages of vane pump :

The hydraulic vane pump is trusted by many customers not only because of its popularity, good price, but also because there are many outstanding advantages such as:

+ The pump structure is quite simple, so it is easy to repair and maintain periodically.

+ If you ensure the good working criteria, the vane pump has a very long life, less damage and breakdown.

+ The special thing is that with vane pump, customers can change and adjust pump flow.

+ The pump has high working efficiency and stability.

+ When operating the pump, it does not make much noise.

+ Pumps have many types with many different pump capacities to meet all diverse requirements of customers.

- Disadvantages of vane pump :

Besides many advantages, there are still disadvantages of hydraulic vane pump that when buying or installing customers need special attention such as:

+ Pumps only achieve the highest efficiency with common hydraulic fluids: oil, water. For the more specific properties of viscosity, consistency, high pressure, a vane pump is not a reasonable suggestion.

+ As mentioned above, the flow rate and the impeller of the pump are related to each other. Flow depends on the number of vaneers. If the pump is small, the number of impellers is small, it does not guarantee a uniform flow and more.

+ If the pump works at a high speed, the problem posed is the corrosion of the vane.

Usually, the vane pump often has problems such as: When it works for a long time, it is too hot, the pump leaks, the fluid pumped does not flow out, loud noise ... All can be overcome through the pressure adjustment, oil filter, pump cleaning, seal replacement ...

The application of vane pumps is very diverse in industrial production, handicraft with industries: processing, manufacturing, manufacturing, assembling, processing with lathes, drills, presses, crusher, presses, cutting machines ...

We can easily find internal single-acting vane pumps and dual-acting vane pumps:

+ Manufacturing chemicals, building materials

Food and food processing industry, beverage production

+ Metallurgy industry, pressure casting

Automotive production and assembly industry

+ Hydraulic oil press system with low and medium capacity

+ In hydraulic systems serving ships and motor vehicles

+ Some machines in service of construction works, hydroelectricity, coal and mineral exploitation.

If you need a hydraulic fluid suction device: oil, oil, soap, cleaning chemicals, adhesives, animal feed or wood chemicals, sugar, syrup, alcohol ... at affordable prices If the quality is guaranteed, choose the vane pump right away.
