The gear pump is used in automotive hydraulic systems, as well as in various industries. The fact is that such devices can pump liquid of varying degrees of viscosity and are strong enough, so they can be used for a long time.
The device is used in the chemical (for pumping alkalis, shampoo, emulsions, oil products), food (pumping cocoa, caramels, honey cream), petrochemical and paint and varnish industries. Moreover, the unit can process a huge amount of liquid.
The gear pump has a fairly simple device. It consists of several working chambers, which are formed by the working surfaces of the wheels with teeth. The whole mechanism is housed in a robust case made of cast iron, steel or aluminum, and closed with side covers. A feature of the device is a small number of components. The advantage of the unit is also the fact that the elements can be easily replaced in the event of a breakdown. Thanks to these features, the pump is in demand and is widely used.
It should be noted that the gear pump can be multi-section, with external or internal gearing, the second option being more compact. You can also select multi-stage devices. As for the gears, the teeth in them can be either chevron or oblique. The most common is the unit with external gearing. It should be noted that the devices may have different volumes.
Gear pumps have many advantages:
- provide high performance and uniform fluid flow;
- simple and reliable in operation;
- can pump a wide variety of viscosity fluids;
- they can be used for quite a long time, and it is not difficult to care for them.
However, you need to be careful when choosing a device, because if low-quality spare parts were used in its manufacture, they can quickly wear out. Moreover, it is necessary to pay attention to the fact that the teeth are uniform, otherwise the fluid flow will be uneven.
The gear pump, the principle of which is quite simple, is very common today. It works as follows: an engine is installed inside the housing, on which the drive gear is mounted, it firmly engages with the teeth of the remaining elements. These elements are driven by the leading part. When the pump is turned on, the teeth capture the liquid and move it towards the supercharger, squeezing it against the housing walls. Thanks to her, device detailsable to cool, so the device does not overheat.
The internal clutch gear pump should be used at low pressures, as they are small in size, and therefore their performance is low. Therefore, if you need to use an apparatus that can withstand high pressures, then it is better to use multi-stage devices. In order to provide multiple fluid flows that will not depend on each other, multi-gear devices are used.
