vertical shaft hydraulic pump made in china

Vertical Turbine Pumps is a new product produced according to the requirement of market. It adopts the best and advanced technology in its design and manufacture. The pumps are not only reliable,high-efficient, but also easy for installation and maintenance.

Vertical Turbine Pump is widely used for transferring those fluid with temperature below 55℃, like the clear water, rain, iron oxide skin water, sewage, corrosive industrial effluent and sea water in power stations, metallurgy industries, fire-fighting industries, mines, iron-works and public industries and so on. The transferring fluid’s temperature temperature could also reach 90℃ through our special design.

The suction inlet of Vertical Turbine Pumps  is straight downwards, and the outlet is horizontal. The pump and the motor could be connected directly and installed on the same foundation, or the pump could be connected to diesel engine through gear box. The rotating is anti-clockwise viewed from the motor end. The main features are as below:

Vertical Turbine Pumps  is designed through the hydraulic design software. It has superior performance and its impeller and impeller body are anti-abrasive which has increased those part’s service life. It operates steadily, safely and efficiently.

The strainer mesh is installed on the pump inlet. The proper sized holes on the mesh not only prevent those big impurities from going inside and causing damage, but also ensure the inflow amount and thus its high efficiency.

The middle shaft, column pipe and protective pipe could be multi-burl. The shaft is connected through screwed coupling or muff coupling. The number of the column pipes could be increased or decreased to meet the submerged depth. The impeller could be single stage or multi-stage to meet the different requirement of the head.

The column pipe is connected by flanges with guide bearing in the middle. The guide bearing adopts the material of PTFE or cellon or butadiene-acrylonitrile rubber. The protective pipe is used to protect the shaft and the guide bearing. If the pumped medium is clear water, there is no need for protective pipe and the guide bearing could go without external cool lubricating water. If the pumped medium is sewage, the protective pipe needs to be installed and external cool lubricating water should also go to guide bearing. Vertical Turbine Pumps  has its self closing seal system which could present the sewage from going into the guide bearing after the shut-down of pump.

The remaining axial force of pump and the weight of rotor parts is borne by thrust bearing in motor seat or motor with thrust bearing. The thrust bearing is lubricated by grease or oil. Pump shaft seal adopts packing seal. There is replaceable shaft sleeve in shaft seal and guide bearing to protect shaft. The axial location of the impellers are adjusted through upper parts of the thrust bearing or pump coupling, which is very convenient.

This study designs three connection schemes of different shaft lengths by modeling software. The keyway, sleeve couplings and other parts are simplified accordingly on the basis of not affecting the basic structure of the shafting rotor. Such a way can reduce the number of grids of the shafting rotor under the premise of ensuring a higher grid quality to shorten the calculation time. Combining the original shaft design of the XBC18-178-240LC3 model and the actual processing capacity of the pump factory, three single-segment intermediate shafts denoted as Z4, Z5 and Z6 shafts are shown in Fig. 8. Each part of three intermediate shafts is the same, apart from the length of the middle part.

Figure 9b is the original model of the VLSFP shafting rotor, which consists of 7 single shafts (1 impeller shaft, 5 intermediate shafts and 1 drive shaft) through the sleeve couplings, and the design parameters of each part are introduced in detail in “Model introduction” section. This model is referred to as Z5 model, since it has 5 intermediate shafts. Similarly, Fig. 9a,c show the models with 4 and 6 intermediate shafts, referred to as Z4 and Z6, respectively. All parts of shafting rotor are the same in the three models, except for the length and number of the single-intermediate shaft, and the total length of the shafting rotor remains unchanged.

ANSYS Workbench18.0 is used to perform statics analysis of the rotor. It is necessary to set the boundary conditions of the rotor according to actual conditions. The boundary conditions refer to the loads and supports. For the VLSFP of this paper, three kinds of loads are considered: the fluid force, the gravitational force and the centrifugal force. The fluid force is loaded to realize unidirectional fluid–structure interaction. Here, the fluid–structure interaction refers to a multi-physical field coupling between the laws describing fluid dynamics and structural mechanics. When a flowing fluid contacts with a solid structure, the structure is subjected to the stresses and strains, and these forces deform the structure. In addition, the gravitational force is loaded by adding a vertical downward gravitational acceleration, and the centrifugal force is loaded by adding the rotation speed. For the choice of constraints, since the shafting rotor is cylindrical, the “Cylindrical Supports” are loaded on the bearing’s locations to limit the axial and radial displacement of the rotor. Besides, the “Remote Displacement” is loaded on the top surface of the drive shaft to restrict the rotation of the rotor, except the axial rotation.

ANDRITZ has incorporated a hydraulic device to adjust the impeller blade angles on its vertical line shaft pumps from the VLSP series to react to changing conditions while the pump is operating.

Power plants commonly experience changes in the cooling water flow rate and head (e.g. day/night operations or tidal fluctuations). So, additional flexibility beyond fixed-angle impellers or manually adjusted impellers is needed. There are typically two ways to achieve that flexibility: speed control with a frequency converter or hydraulic impeller blade adjustment. ANDRITZ delivers pumps with either type of adjustment. So the question arises, “When does it make sense to use the hydraulic impeller blade adjustment?” The brief answer is that it depends upon the specific application: range of fluctuation in delivery rate and head, other installed equipment, budget available, etc. The specialists at ANDRITZ will help in the evaluation and selection.

The hydraulic adjusting device has clear advantages when there are substantial changes in delivery rate. With its ability to vary the impeller blade angle up to 15° between minimum and maximum, it can be a perfectly acceptable alternative. It is proven highly reliable. The beauty of the adjustable-angle impeller blades is that it is possible to compensate for changes in operating conditions while the pump is in operation. In this way, the efficiency can be optimized or the duty point changed on-the-fly. It has a long service life and does not require any electronic spare parts.

The suction inlet goes down vertically and the spit outlet extends horizontally. According to the form of foundation, the long shaft pump with double foundation structure can be produced; according to the axial thrust, there is not only the structure of the pump bearing the axial thrust, but also the structure of the motor bearing the axial thrust. According to the form of the rotor, the non-extractable structure of the rotor can also be produced at the same time. The impeller can be made into one stage or multi-stage. The high lift long shaft pump has a unique structure invented by ourselves, the secondary impeller rear structure, the different head combination structure under the same flow rate, and the unique pressure relief structure at the packing body. The standard seal is a packing seal. Draw water from a suction pool or directly from rivers or oceans.

Pump shaft seal for the vast majority of packing seal structure, at the same time can also use integrated mechanical seal structure, water guide bearings according to user requirements, using a variety of configurations, the standard configuration of polytetrafluoroethylene and rubber guide bearings, sea water is generally configured for Sailong guide bearings, high-end configuration for AR bearings and ceramic bearings. The lubrication of the water guide bearing can be determined according to the water quality, and the good water quality can be directly lubricated by the water of the pump body itself. if there are particles or sand shafts in the water quality, a protective pipe can be set up to connect the clean industrial water lubricated water guide bearing to prolong the service life of the sleeve and bearing.

The long shaft pump has the advantages of wide high efficiency area, small vibration, not easy to produce cavitation phenomenon, stable operation of the pump group, and is not prone to failure.

The high efficiency area of the pump is wide, and the pump head is submerged in water, so it is not easy to produce cavitation after meeting the requirement of minimum submerged depth.

The core-pulling structure is convenient for maintenance, and the part of the rotor can be extracted for maintenance under the condition that the pump shell and pipeline are not moving.

Hello, the oil pump damage, will lead to insufficient oil or will not provide oil in the body parts of the lubrication, such as the size of the tile can not get the lubrication of oil, so that lead to burning tiles and other phenomena, thank you for referenceQ:4Y engine oil pump, okay? Still lifting the engine?

1, the phenomenon is generally rhythmic sound, the sound is on the side of the camshaft, the noise is more than when the gear meshing uneven sound sharp. At low engine in speed, sound obvious and clear; increase the solar term door opening, the sound increases and becomes messy. In a few cases, a very heavy "click" sound can be heard, as if the camshaft bearings are seriously loose.2, reason oil pump shaft, distributor drive shaft bending or axial clearance is too large: oil pump drive main and driven gear, distributor drive, driven gear, crash or wear and tear deformation.3, check and judge this sound "fire test" test is invalid, you can touch the stethoscope at the lower end of the distributor body auscultation. If the noise is obvious, the body has a slight vibration, can be repeated from idle to low, medium speed throttle test. If the sound changes, as mentioned above, it may be this sound. If you hear a heavy click or click, as if the camshaft bearings are loose and loose, it is possible that the oil pump is broken.Q:How do I see the motorcycle"s oil pump is broken? Two red

Hello, friend. First of all, tell you that the two stroke motorcycle does not have an oil pump. If it"s a four stroke. In 70, 90100 of the three models you can put the screws on the cylinder head of the lower right to loosen the. Then start the locomotive. If there is oil to the outside, then that the normal oil pump. If not, check the oil pump wheel for wear first. Because the oil pump wheel wear, even if the oil pump is not bad. It doesn"t work either. The three models are identical in structure. Their oil pumps and pump wheels are relatively easy to break. Another 125 models, men"s and women"s pedals. Men"s words a screw is loosen cylinder head top, then start. Organic oil emits just normal. No oil smoke, also want to look at the screen is not blocked. The screws on the ladies pedal are the same as the 7090100Q:What is the cause of engine oil alarm?

Oil lamp alarm reason::1, the amount of oil is insufficient, so that the pump oil pump volume reduced, or because of air into the pump does not oil, resulting in lower oil pressure;2, the engine temperature is too high, easy to make oil thinning, from a large gap in the gap between the resulting oil pressure drop;3, when the oil pump parts damage or wear, assembly and other problems arise when the gap is too large, will cause the oil pump out of oil or the failure of the oil shortage;4, the crankshaft and large, small tile gap between the improper, too tight will make the oil pressure rise, too loose will make the oil pressure lower;5, the oil filter and oil suction disc plug will also reduce the oil pressure;6, the oil return valve damage or failure: if the main oil return valve spring fatigue softening or improper adjustment, the valve seat and the ball with the surface wear or dirt stuck and closed, the oil return amount will increase obviously, oil pressure of the main oil channel also decreased;7, improper selection of oil: if you use the wrong or improper selection of grades, the engine will run when the oil viscosity is too low and increase the leakage, thereby reducing the oil pressure;8, the oil pipe in the oil leakage, plug phenomenon.Only normal oil pressure can ensure that the oil is sent to all the friction parts of the engine, too high or too low will affect the normal operation of the engine, and even cause damage to engine parts. So, when the alarm lamp should be immediately shut down to find out the reasons, troubleshooting before it can continue to work.Q:How does the motor pump exhaust the air?

In the premise of the normal amount of oil, usually need to check whether the oil pressure is normal (usually around 0.3MPa), if the oil pressure is low, usually the oil circuit, overflow valve failure or oil pump failure. After cleaning and adjusting the oil relief valve, the pressure is still low. The fault must be the oil pump failure.The effect of the oil pump is to press the engine oil to a certain pressure and force it to the surface of each part of the engine. If the oil pump is damaged or leaking, it is necessary to disassemble the oil pan, take out the oil pump and replace it, and clean or replace the oil pump inlet strainer at the same time.Q:What"s the cause of the indicator light of the car oil pump?

It"s the oil pressure indicator, not the oil pump indicator light.This indicator is used to show the pressure of the engine oil. Open the key door. When the vehicle starts to self check, the indicator light is on and off after starting. The indicator light is always on, indicating that the engine oil pressure is lower than the required standard, you need to repair.If it"s on all the time, just see if the oil is enough. How about the oil pressure switch, the wiring harness and the plug?. If it is flashing at some point, the possibility of a problem with the oil pressure switch itself is greater.Q:Sonata 6 cylinder morning taxi dadada big sound like the Volkswagen B5 engine chain expansion broken chain to the valve cover sound, car temperature reached 90 is not loud, and a high speed with the speed of 120 continuous driving not more than 20 kilometers, over 20 kilometers, more like a car with no oil if the valve is inside the chaos ring, and three cylinder ring, the outside does not ring, beg you master to solve!

Hello, in the morning to start the car, generally not the oil pump sound, the chain is issued by the sound, because the car just did not come up with oil
