What Is The Failure Of The Hydraulic Pumps?
Before figuring out the cause of a hydraulic pump failure, it is important to know that the hydraulic pump is malfunctioning or there are signs of danger of malfunction. These signs include:
Noisy systems: All mechanical systems make noise, and hydraulic systems are no exception. However, if you hear a loud knock or knock, it is likely that your system is inflated or cavitation, which may cause the pump to malfunction.
High temperature: If the temperature of your hydraulic system exceeds the recommended 82 degrees Celsius, the system may not be able to dissipate heat due to debris accumulated in the filter. You will want to solve this problem quickly, because high temperatures can damage your system.
Slow system: If your system does not run as expected, then you must have a problem. A slow hydraulic system means flow loss, which usually means internal leakage.
What makes the hydraulic pump fail
The main cause of hydraulic pump failure is called fluid contamination. This is because the hydraulic oil is invaded by foreign matter. Hydraulic pumps and valves are only designed to carry hydraulic oil, and anything else in them can damage the system, especially because these foreign objects may remain in the system and continue to damage the valves and pipelines.
Other conditions that may cause hydraulic system failure include:
Aeration: Hydraulic oil can cause problems under pump pressure. When this happens, they may burst and remove debris, causing contamination and increasing the temperature inside the pump.
Cavitation: Cavitation refers to the abnormally high viscosity of the hydraulic oil, the excessively long intake pipe or the overspeed of the pump, etc. The hydraulic oil cannot completely occupy the space in the pump. It may cause problems similar to inflation.
Excessive heat: Overheating of the hydraulic system will cause some serious problems to your hydraulic system. It may damage the seals and reduce the performance of the hydraulic oil, otherwise it will damage the system.
Overpressure: The hydraulic pump system is very sensitive and can only operate under certain conditions, including precise pressure levels. Exceeding the recommended pressure level will cause unnecessary stress and wear to the system and may cause the system to fail more quickly.
How to avoid hydraulic system failure
The best way to avoid hydraulic system failure is to keep the system clean. Remember: fluid contamination is the main precursor of hydraulic system failure, therefore, removing these contaminants from the system is the best opportunity to maintain the health of the hydraulic system. This means that you need to check the high-quality filters in the system regularly and replace them if necessary.
Another main way to keep the hydraulic system running is to keep the parts cool. An overheated system can cause real problems, and you may not notice this effect until it is too late. You also need to ensure that the system is operating at the correct pressure specifications.
A well-maintained hydraulic system can last a long time and is extremely efficient. Although many problems can occur with hydraulic systems, most problems can be avoided with proper care, and the benefits of providing a good hydraulic system for your business can be huge-it is worth keeping the system properly.
Part of these measures is to take quick measures when necessary. If you suspect that there is a problem with one or more components of the hydraulic system, the best way is to have a professional inspect it and repair any malfunctioning parts that are malfunctioning or at risk of malfunction. The longer you allow hydraulic system problems to be resolved, the more serious the consequences of failure.

The Structure Of The Hydraulic Pumps
The hydraulic pump is used to excite fluid from a lower potential to a higher potential. It has several mechanical movement components that receive energy from any other source (mainly electricity). Most hydraulic pumps have rotating parts, and these rotating parts run on power. The basic components used in hydraulic pumps are:
Pump housing/Pump housing: This is the external part of the hydraulic pump to protect the internal components. Smaller pumps use aluminum as a construction material, while other pumps use cast iron.
Impeller blades: The impeller blades will rotate in the pump casing. The rotation of the impeller blades will rotate the surrounding fluid, so that the fluid flows at a higher potential. Moreover, they also play an important role in the lubrication and cooling of the system.
Pump shaft: The pump shaft is used to install the impeller. Steel or stainless steel is used to construct the shaft, and the size depends on the impeller.
Bearing assembly: assisting the continuous rotation of the impeller is the function of the pump bearing. Most centrifugal pumps use standard spherical anti-friction bearings.
Sealing: Most pumps fail due to damage to the bearing components. The seal will eliminate the risk of failure to a greater extent by protecting the bearing assembly from contaminants and coolants.

About Internal Gear Pumps
Internal gear pumps are very versatile and can pump many different types of fluids in a variety of viscosity and temperature ranges. Internal gear pumps use two gears to transport fluid. The rotor gear is located on the outside, and the smaller idler gear is nested inside.
How does this work
When the rotor (outer) gear rotates, it drives the idler (inner) gear. When the idler gear is out of contact with the rotor gear, the liquid is sucked into the pump and flows along the housing to the discharge side of the pump, where the gear teeth mesh together and force the fluid to drain from the pump.
What do they do
Internal gear pumps are ideal for high-viscosity fluids. They are also very useful for situations that require low NPSH. Since there are only two moving parts, maintenance costs are also very low.
What they are not suitable for
Internal gear pumps are not suitable for large solids. Because of their small tolerances, large solids can easily damage the pump. They can handle some small suspended solids in abrasive liquids, but it should be noted that this will cause the pump to wear and lose performance

Influence Of Oil Pumps On Engine
The oil pump in the internal combustion engine circulates the oil under pressure to the engine's rotating bearings, sliding pistons and camshafts. This lubricates the bearings, allows the use of large-capacity fluid bearings, and also helps to cool the engine.
In addition to the main purpose of lubrication, pressurized oil is also increasingly used as hydraulic oil to power small actuators. One of the first notable uses of this method was the hydraulic tappet used in camshaft and valve actuation. Recently more and more common uses may include tensioners for timing belts or transmissions for variable valve timing systems.
Not all engines have the same oil injection requirements. For example, high-performance engines put more pressure on the lubrication system. In this case, the lubrication system must be particularly robust to prevent engine damage. Most car engines on the road today do not exceed 5,000–6,000 rpm, but for high-performance engines, this is not always the case, because high-speed engines may be as high as 8000-9000 rpm. In such engines, the oil must circulate fast enough, otherwise the air may be trapped in the oil. Similarly, in order to release power, the engines in some high-performance applications run on lighter oil, which requires less power to run the oil pump. Nowadays, the weight of common engine oil is usually 5W-30 or 10W-30, while high-performance engines may use 0W-20 engine oil with low viscosity

Hydraulic Vane Pumps : 3 Industry Application Characteristics
The function of the pump is essential for many industries, and different pumps can be used to complete work in various industrial environments. One of them is the rotary vane pump, which works according to the positive displacement principle and is widely used in various industrial and commercial applications.
Components involved in vane pump function
The main components of the rotary vane pump system include the pump casing, the outlet, the installed rotor, the intake valve and the vanes, which meet under a common center under the action of the spring force. The pump casing has two openings, namely the inlet valve intended to be used as a vacuum safety valve and the outlet valve sealed by oil. These components exist in the working room, which is located in the pump housing. The rotary vane pump is based on a resource-rich electromagnetic motor, so it is fast, efficient and noiseless. Depending on the cylinder size and rotor, these pumps can bring more volume per minute, so they can reach higher vacuums faster. Special pump oil is required to ensure its smooth operation and maximum vacuum.
Application of rotary vane pump
There are many well-known vane pump manufacturers in the country, which provide high mechanical efficiency. This ensures their smooth operation in a variety of applications; the most important is the automotive sector.
Important position in the automotive industry
The pump enters multiple parts of the vehicle, for example:
• Power steering
•brake
• Boost
• Automatic Transmission
Vacuum pumps are used with brake boosters to provide braking in large trucks. In addition to automobiles, vane pumps have also entered light aircraft systems.
On an airplane, they help:
• Heating and altitude indicator
•Gyro
Medium and low pressure applications
Some low-pressure gas applications for pumps include evacuating refrigerant lines and controlling automatic exhaust emissions through secondary air injection. Other medium-pressure applications for pumps include use in carbonated soft drinks and espresso machines.
Laboratory experiment
The rotary vane pump has become an indispensable means of vacuum experiment in the field of physics, and thus has entered the field of education. Here, the oil and the pumped gas are mixed in the pump. Both must be separated from each other externally. When the outlet and inlet chambers are large, the oil droplets fall as the gas rises. In the end, both exit through the exit and are therefore separated from each other.
Zhejiang Yongling Hydraulic Machine Co , Ltd. is a large-scale manufacturer and supplier of Hydraulic Vane Pumps and V/Vq Series Vane Pumps . V/Vq series vane pumps have unique filter element design in the vanes, and have the characteristics of maintainability, high efficiency and long service life. It is suitable for industry.
