How to slow down the hydraulic oil circuit driven by the gear pump?

When choosing a lobe pump, you need to consider other names, application disciplines, pinyin and other factors. The applied discipline is mechanical engineering; Transmission; Hydraulic transmission. Lobe pump technology started in Germany in the 90s.

Its technical characteristics are perfect, its rotor is fully covered with spiral three-blade special rubber, with high vacuum degree and super wear resistance, corrosion resistance, is widely used in military industry, oil exploitation and other fields. At present, the domestic production of lobe pumps is mainly based on metal lobe pumps, the technology is mainly used in the field of food and chemical industry, the cam rotor and the pump body gap match, resulting in the pump in the transport of particles easy to get stuck pumps, the overall efficiency is not high. At present, the domestic lobe pump technology is gradually developing towards more advanced rubber composite screw lobe pumps, which is currently mainly monopolized by German technology.

The rubber composite screw lobe pump is wrapped with composite rubber....

Deceleration, or more accurately, lowering the flow rate. This can be solved by both pumps and valves.

1 The gear pump itself cannot be variable, and the best thing to do is to reduce the speed of the motor (or other prime mover) to radically reduce the flow rate.

2 Throttle valves, speed control valves, proportional valves can be used to change the flow rate into the hydraulic motor, so as to slow down.

Whenever possible, the first method can be used to avoid the oil temperature of the system being too high.

If the output speed is fixed, a reducer can be added If the output speed is varied, the motor can be controlled with a frequency converter.

It is recommended that you install a relief valve.

Summary. Hello dear, happy to answer your <>

Hydraulic oil can drive the rotation of the gear pump. A gear pump is a fluid machine, mainly composed of gears and housings, which uses the meshing between gears to make the liquid enter the pump cavity from the suction end, and then push the gears to rotate and discharge the liquid by pressure. In hydraulic systems, gear pumps are usually used as hydraulic pumps, which are responsible for pumping and pushing hydraulic oil from the low-pressure side to the high-pressure side, so as to realize the work of the hydraulic system.

Therefore, the hydraulic oil can be driven by the rotation of the gear pump to promote the flow of liquid, and realize the conversion and transfer of hydraulic work.

Can hydraulic oil drive a gear pump to turn.

Hello dear, happy to answer your <>

The hydraulic oil can drive the rotation of the source gear pump. A gear pump is a fluid machine, mainly composed of gears and housings, which uses the meshing between the gears to make the liquid enter the pump cavity from the suction end disturber, and then pushes the gears to rotate and slowly discharge the liquid through pressure. In hydraulic systems, gear pumps are usually used as hydraulic pumps, which are responsible for pumping and pushing hydraulic oil from the low-pressure side to the high-pressure side, so as to realize the work of the hydraulic system.

Therefore, the hydraulic oil can be driven by the rotation of the gear pump to promote the flow of liquid, and realize the conversion and transfer of hydraulic work.

Dear, the following is a related extension, I hope it will help you<> hydraulic oil can drive the gear pump to turn. Hydraulic systems typically use fluids to transfer energy and drive machine drains, with hydraulic oil being one of the most commonly used fluids. Gear pump is a commonly used hydraulic pump, which works by producing hydraulic energy by pushing the rotation of gears by hydraulic oil.

When the hydraulic oil enters the suction port of the gear pump, the pressure twig of the hydraulic oil pushes the gears to start rotating. As the gears rotate, the hydraulic oil is compressed and pushed to the outlet port, increasing the pressure in the hydraulic system. This pressure can be used to perform various mechanical operations such as push cylinders, drive motors, etc.

As a result, the hydraulic oil can drive the gear pump to rotate and generate hydraulic energy.

Summary. Yes, there are transmission gears in the hydraulic transmission system. Hydraulic transmission system is a system that uses hydraulic force to transmit power, which is composed of hydraulic pumps, hydraulic motors, hydraulic cylinders, hydraulic controllers, hydraulic valves, hydraulic pipelines and transmission gears.

The transmission gear is an important part of the hydraulic transmission system, and its role is to convert the hydraulic force into mechanical power, so as to realize the movement of mechanical equipment. There are many types of transmission gears, such as rack and pinion, gear chain, gear belt, etc., and their structure and characteristics are also different, and the appropriate transmission gear can be selected according to different application needs.

Can you add, I don't quite understand it.

Yes, there are transmission gears in the hydraulic home. The transmission gear rental shield wheel is an important component in the hydraulic system, which can convert the power in the hydraulic system into mechanical energy, so as to realize the control and transmission of the hydraulic system. Transmission gears can have problems in hydraulic systems, and the most common problem is gear wear.

The causes of gear wear can be insufficient lubricating oil, poor lubricating oil quality, lubricating oil contamination, lubricating oil temperature is too high, gear accuracy is not enough, etc. To solve the problem of gear wear, we must first check the quality and temperature of the lubricating oil, ensure that the lubricating oil is of good quality, the temperature is appropriate, and replace the lubricating oil regularly. Secondly, the accuracy of the gear should be checked to ensure that the accuracy of the gear meets the design requirements.

Finally, it is necessary to regularly check the wear and tear of the gears, find problems in time and take measures to repair them. Personal tips: When using the hydraulic system, you should pay attention to the quality and temperature of the lubricating oil, ensure that the lubricating oil is of good quality, the temperature is appropriate, and the lubricating oil should be changed regularly; Regularly check the accuracy of the gear to ensure that the accuracy of the gear meets the design requirements; Regularly inspect the wear of the gears, identify problems in time and take measures to repair them.

Summary. 1.First of all, check whether the rotation direction of the gear pump is correct; Secondly, check whether the filter at the inlet end of the gear pump is clogged.

1.First of all, check whether the rotation direction of the gear pump is correct; Secondly, check whether the filter at the inlet end of the gear pump is clogged.

2.The oil seal is flushed out of the gear pump bearing by axial force; The gear pump is subjected to excessive radial forces.

My motor is 400 and the gear pump is 320, can this match work properly?

Normal. The oil seal of the gear pump has been flushed out, and the oil has been poured from the shaft, what is the reason for this situation?

Is it the reason why the gear pump is rotating in the wrong direction?

What about people? This phenomenon is mostly related to the cleanliness of the liquid pressurized oil, such as the incorrect selection of oil or the cleanliness of the oil in use does not meet the standard requirements, which will accelerate the internal wear of the pump and lead to the leakage. Therefore, mineral hydraulic fluids containing additives should be used to prevent oxidation and bubbles in the oil.

The viscosity standard of the oil is (16 80) 10-6m2 s, and the filtration accuracy is: the input oil circuit is less than 60 m. By observing the shaft sleeve and side plate of the faulty gear pump, it is found that if the cleanliness of all the oil is poor, it will cause obvious grooves on the surface of the friction pair, while the normal wear and tear of the gear pump will only produce uniform surface marks.

In general, it is not possible to replace the gear pump with a residue pump to pump hydraulic oil. This is because there is a big difference between the residue pump and the gear pump in terms of structure and working principle, and their applicable working conditions and liquid properties are also different. A gear pump is a commonly used hydraulic pump that generates the pressure to suck in and drain the liquid by meshing between two gears.

It has a certain wear resistance and high work efficiency, and is suitable for pumping hydraulic oil and other liquids. Residue pumps, on the other hand, are typically used to pump highly viscous residues, residues, or media containing particulate matter. Its structure and working principle are suitable for such special media, but it is not suitable for pumping clean liquids such as hydraulic oil.

Therefore, in order to ensure the normal operation of the hydraulic system and protect the equipment, it is recommended to use a suitable gear pump or other special hydraulic pump to pump the hydraulic oil. If there are special needs or situations, please consult a professional engineer or hydraulic equipment manufacturer for more accurate advice.

The key to increasing the operating pressure of a gear pump is to effectively reduce the internal end leakage. The current method is to use an automatic face clearance compensation device. Its working principle is to direct the pressure oil in the pressure chamber of the pump to the outside of the bushing or side plate, so as to automatically compensate for the wear of the end face and reduce the end face clearance.

A typical structure with a floating bushing. Bushings 1 and 2 are floatingly installed, and the left cavity of the bushing is connected with the oil pressure chamber of the pump. When the pump is working, the bushings 1 and 2 move to the right due to the action of the pressure oil on the left side, compressing both sides of the gear, thus automatically compensating for the end face clearance.

In this way, the rated pressure of the gear pump can reach 10 16MPa, and the volumetric efficiency is not less than.

In order to improve the pressure and volumetric efficiency of the gear pump and realize the high pressure of the gear pump, it is necessary to take measures from the structure and automatically compensate for the end face clearance. There are two kinds of automatic face clearance devices that are commonly used: floating shaft sleeve type or elastic side plate type.

The principle is to introduce pressure oil to make the shaft sleeve or side plate close to the gear end face, the higher the pressure, the smaller the clearance, which can automatically compensate for the end face wear and reduce the clearance. The floating sleeve of the gear pump is floatingly installed, and the cavity on the outside of the sleeve communicates with the oil pressure chamber of the pump, when the pump works, the floating sleeve is pressed to the end face of the gear by the action of oil pressure, and the two sides of the gear are compressed, so as to compensate for the gap of the end face.

The pressure depends on the load, if you want to make the working pressure of the system larger, it depends on the size of your load, and you should also pay attention to the size of the pressure set by your relief valve, otherwise the relief valve will overflow the pressure and not go up, but you should pay attention to the size of your motor when adjusting, don't overload the motor.

If it is the same pump, there is only one way to reduce leakage, and then match the corresponding motor!

Hello dear <>, about the high-pressure oil pump gear, the following is the result of your query, 1. Remove some parts of the original machine: remove the gear chamber cover, the camshaft has a high-pressure pump cam, and now pull it out and replace it with a camshaft with a taper surface at the outer end of the hidden search without a high-pressure pump cam. 2. Install it on the cover of the gear chamber where the oil pump of the early device can be installed

Attach the speed regulating adapter rod and high-pressure oil pump on the original gear chamber cover to the gear chamber cover where the early installer can be installed. When installing the high-pressure oil pump, the three fixing bolts are not tightened temporarily. 3. Install an early device:

Adjust the keyway on the cone of the camshaft to the upward facing position and insert the semi-circular key. Carry the day.
