The working cycle of internal gear pump is divided into three stages: filling, transmission and delivery. When the gears are detached from the pump inlet side, they will produce a larger volume. As the gear continues to rotate against the pump housing and diaphragm, liquid flows into the cavity and is captured by the gear teeth. The trapped fluid moves around the sleeve from the inlet to the...

The balanced vane pump is a very versatile design that has been widely used in industrial and mobile applications in both pumps. Basic design principles. The rotor blades are contained in a double eccentric cam ring, and there are two intake sections with two outlet sections each time they rotate. This double pumping action not only makes the compact design, but also brings another important...

Internal Gear Pumps    can pump fluids of almost any viscosity, but for thicker materials, the speed must usually be reduced. They are not suitable for materials containing solids because they can cause premature wear. Internal gear pumps are self-priming and can be used for low NPSH applications. They usually provide smooth and continuous flow. In theory, at least they are...

In fact, each individual hydraulic power transmission system uses a hydraulic pump. A hydraulic pump is a device that converts mechanical energy into hydraulic energy. Hydraulic energy is a combination of pressure and flow. A hydraulic pump can be any device that can input force to generate pressure, and pressure can generate flow. The basic hydraulic pump is a manual pump for any low-power...

1. When replacing the pump core, first check whether the positioning hole in the pump casing is deformed, and whether the matching part of the external spline and the internal spline of the pump core is worn or deformed. If the positioning hole is deformed or the shaft key is worn, it is recommended that the user replace the entire pump. 2. Check whether the shaft seal is aging and deformed,...

Every mechanical part needs maintenance, as does the hydraulic pump. Obviously, proper maintenance can keep the mechanical products in good condition. Otherwise, improper maintenance may cause many problems, which in turn will lead to more serious problems. Therefore, you should perform some preventive maintenance to avoid unnecessary failures. Preventive maintenance of hydraulic pumps...

Although    Hydraulic Vane Pumps    can handle medium viscosity liquids, they are good at handling low viscosity liquids such as liquefied petroleum gas (propane), ammonia, solvents, alcohol, fuel oil, gasoline and refrigerants. Vane pumps have no internal metal-to-metal contact and can self-compensate for wear, allowing them to maintain optimal performance on...

The     Oil Pumps   is an important part of the lubrication system, which can pressurize the oil to distribute it around the engine. It is usually related to internal combustion engines. Oil pumps are a type, also known as hydraulic pumps or submersible pumps. These pumps can pressurize the hydraulic oil in the hydraulic system. The application range of hydraulic...

1. Liquid enters the suction port between the rotor (larger external gear) and idler (smaller internal gear). The arrow indicates the direction of the pump and liquid. 2. Liquid flows through the pump between the teeth of the "gear internal gear" principle. The crescent shape separates the liquid and acts as a seal between the suction port and the exhaust port. 3. Now, before forcing the...

Internal Gear Pumps    are self-priming and can dry up, although if the gears are wet, they will also improve their oil absorption characteristics. The gear needs to be lubricated by the pumped liquid and should not be idling for a long time. Some gear pump designs can run in either direction, so, for example, the same pump can be used to load and unload containers. Tight...
