What is the impact of a bad airbag without negative pressure water pump

What is the impact of the bad airbag of the non-negative pressure water pump:

1. Unable to start.

1. Reason: the packing is too tight or the impeller and the pump body are stuck by debris and blocked; Pump shafts, bearings, and leakage reduction rings are rusted; Severe bending of the pump shaft, etc.;

2.Workaround:

Loosen the filler and dredge the drainage tank; Disassemble the pump body to remove debris and rust; Remove the pump shaft to calibrate or replace it with a new one.

2. Violent vibration.

1. Causes: unbalanced electric rotor, bearing wear and bending, pipeline support is not firm, etc.;

2. Solution:

Take adjustment, repair, reinforcement, replacement and other methods.

3. The water pump is heated.

1. Reason: Bearing damage.

2. Solution:

replacement of bearings; Remove the back cover and install a gasket between the bracket and the bearing seat; Investigate the pump shaft or adjust the concentricity of the two shafts; Adjust the tightness of the tape appropriately; Fill with clean butter, butter accounts for about 60% of the void in the bearing; Remove blockages from the balance holes.

Fourth, the amount of liquid output is small.

1. Reason: the motor is not right-turned; The center line of the impeller is not immersed in the liquid;

2. Solution:

adjust the phase; Adjust the immersion height.

5. The motor is overheated.

1. Reason: the reason for the power supply (the voltage is high or low); motor provincial reasons; Pumping reasons; reasons for the working environment;

2. Solution:

The insulation resistance of the motor should be measured and cleaned and dried; The ambient temperature is too high. When the ambient temperature exceeds 35, the high inlet air temperature will make the temperature of the motor too high, and the working environment should be improved. Such as building a canopy for shade, etc.

The airbag of the non-negative pressure water pump is broken, which will have a great impact, which will lead to the instability of the effluent flow and outlet pressure.

1. The water inlet pressure is normal, but the water inlet pressure on the touch screen is displayed as 0-MPA: it may be that the inlet pressure transmitter is not connected, or the wiring is incorrect, or the device is broken, if it is broken, please replace it.

2. The inlet and outlet water pressure deviates greatly from the actual value: the pressure value is more accurate in the touch screen pressure setting.

3. Thermal fault of water pump: check whether the thermal relay has been operated and adjust the rated current. Check the reason why the pump is working.

4. Negative pressure alarm or municipal no water alarm: The pressure of the municipal pipe network is too low, and the alarm will be automatically released when the pressure rises to the negative pressure release value. No water alarm; Check the steady flow tank to see if there is a real shortage of water.

When the water level is restored, the alarm will be automatically discharged.

5. Inverter failure or damage: find the cause of the failure and solve or replace the inverter according to the inverter instruction manual.

6. The inverter frequently reports overcurrent faults, and the possible causes and solutions are as follows:

a.If the valve is opened too large, the pump will overflow and the motor will overflow: close the small outlet valve.

b.The operation is not flexible, and the pump has friction or stuck: check the shaft, bearing and impeller to remove foreign matter from the pump.

c.Incomplete phase loss due to poor contact of the line or contact: Tighten each terminal block and check the contactor and other components.

d.The supply voltage is too low and the current increases: Solve the power supply problem.

e.The motor or cable insulation resistance is not enough, and the leakage current is high: repair the motor or replace the cable.

f.There is a short circuit in the output circuit of the frequency conversion: eliminate the short circuit fault.

7. Manual normal and automatic abnormality: check whether the installation is correct for on-off test; Check the fuse, working mode selection switch, etc. to restore power supply.

8. The overload indicator light is always on: re-tune the thermal relay, close the gate valve of the small water pump, and replace the thermal relay.

1. The system cannot be watered.

1) Check whether there is water in the pool, whether the motor is running, and the motor steering and inverter may be redirected.

2) If the check valve is at the front end of the motor, if there is water at the front end of the check valve, and the water in the motor is emptied.

3) Disassemble the water pump to check whether the welded impeller is broken, which is generally noisy.

2. The pressure is very high at the moment when the pump starts.

1) Check whether the pipeline is blocked, causing a sudden change in pressure (because the flow rate becomes smaller), and check whether the pipeline is leaking, causing the pressure to not be maintained.

2) Generally speaking, the water supply unit is automatic, and its automatic action is to control the switch action of the unit by pressure. The flow rate of the pipeline will also have a great impact, and the automatic decrease in flow will cause the pressure from the outlet to the blockage to increase suddenly as soon as the pump starts, resulting in pressure control malfunction, and the start will be frequent (water leakage will also).

3) Water hammer is generated at the moment of starting the pump.

3. The switch often jumps or cannot be closed.

1) Aging of switches.

2) The switch selection is incorrect.

3) Pump jamming or motor circuit problems.

4) The line is aging, short circuit, the line is too small or the phase is missing.

Generally speaking, there are the following symptoms when the pump is broken:

1. Idle problem, the car water pump is connected with the belt to pump the cold water out of the water tank to cool the engine, if there is a problem with the rotation of the water pump, it will directly affect the speed of the engine.

2. The direct consequence of most pump damage is coolant leakage, which is mostly caused by the aging of the pump seal, in addition, the engine combination belt is too tight and will also lead to premature wear of the pump; If the antifreeze is not replaced for a long time, the internal corrosion will eventually cause damage to the water pump; The pump reaches the end of its service life and does not replace it for a long time.

3. The noise of the engine part, open the cover, start the engine, if you hear the low friction noise, it may be that the water pump bearing is broken. If it's already broken, the sound is obvious.

Car water pumps.

There are several main phenomena that are broken:

1. Water leakage (slight and severe water leakage) Slight water leakage will only leave traces of coolant color on the pump vents. The serious one is the direct water leakage, which leads to the appearance of high water temperature after the lack of coolant;

2. Weak circulation capacity: If the circulation capacity of the pump is weak, the phenomenon of high water temperature will occur, especially in the summer in the south;

3. Abnormal noise; If there is a problem with the internal bearing of the water pump, and there is an abnormal noise under the drive of the belt, it may be mild, and you have not noticed.

Open the lid of the water tank, get on the car and give oil, and watch.

Check whether the water tank is a whirlpool, with the throttle increase the water will be swirling flow very strongly, if the reaction is not big, wait for the water temperature in the hot spot, the electronic fan starts, the thermostat will open the whirlpool, with the change of the throttle the vortex will also change, so that the pump is not broken.

In the cylinder block of automobile engine, there are a plurality of water channels for cooling water circulation, which are connected with the radiator (commonly known as water tank) placed in the front of the car through water pipes to form a large water circulation system, and the upper water outlet of the engine is equipped with a water pump, which is driven by a fan belt to pump out the hot water in the engine block waterway and pump the cold water in. There is also a thermostat next to the water pump, when the car is just started (cold car), it is not opened, so that the cooling water does not pass through the water tank, only circulates in the engine (commonly known as small circulation), when the temperature of the engine reaches more than 95 degrees, it is opened, the hot water in the engine is pumped into the water tank, and the cold wind blows through the water tank when the car moves forward, taking away the heat. Centrifugal water pumps are widely used in automobile engines.

Its basic structure is composed of parts such as water pump housing, connecting disc or pulley, water pump shaft and bearing or shaft bearing, water pump impeller and water sealing device, etc., which is the main component of the automobile.

Failure of the cooling water pump.

The main function of the cooling water pump is to provide the power for the forced circulation of the coolant. If the cooling water pump does not work or the impeller is damaged, it will cause insufficient circulating power and will also cause high temperature of the engine.

Detection method: After the engine high temperature fault occurs, turn on the car heater, if there is no hot air, it means that the coolant is not circulating, either the water pump is broken, or the water channel is not passable. At this time, see if the antifreeze is clean. A clean antifreeze is a sign that the water channel is open, which in turn means that the pump is broken.

In addition, it can also be identified by listening to the sound. The engine belt chirps for no reason, the engine side is noisy, and the belt is still there, then it may be that the water pump is broken.

Electric water pumps need to check the sensors and wiring harnesses. Mechanical pumps need to look at the drive belt, too tight can also cause pump failure.

Car water pump damage The water temperature will rise dramatically.

China water pump trading network for you to answer: the main symptoms of car pump leakage: 1. Water leakage (slight and serious water leakage) Slight water leakage will only leave traces of coolant color on the pump vents. The serious one is the direct water leakage, which leads to the appearance of high water temperature after the lack of coolant; 2. Weak circulatory ability

If the circulation capacity of the pump is weak, the water temperature will be high, especially in the summer in the south. 3. Abnormal noise; If there is a problem with the internal bearing of the water pump, and there is an abnormal noise under the drive of the belt, it may be mild, and you have not noticed.

1. All buttons are invalid.

Solution: Handle the level meter contacts.

Shanghai Weihu Li Bai will answer for you 1. The water inlet pipe is directly connected to the tap water pipe network, and the water is pressed into the inlet pipe of the equipment under the residual pressure of the tap water pipe network; The pressurized water pump of the equipment continues to pressurize on the basis of the residual pressure of the inlet water, and the water supply pressure is increased to the pressure required by the user and then supplies water to the outlet pipe network; 2. When the user's water consumption is greater than the water supply of the tap water pipe network, the pressure of the water inlet pipe network drops, and when the pressure of the water inlet of the equipment drops to the absolute pressure less than 0, the negative pressure prevention and control device in the equipment will automatically start to work; Adjust the operating status of the equipment until the equipment is shut down and standby, so as to ensure that the pressure of the inlet pipe network will not be reduced and the water pipe network will be adversely affected; 3. When the water supply capacity of the tap water pipeline network is restored and the pressure of the inlet pipe network is restored to above the protection pressure, the equipment will automatically start and resume normal water supply; When the residual pressure of the tap water pipeline network meets the water supply requirements of the user, the equipment automatically enters the dormant state, and the water supply is directly supplied to the user by the tap water pipe network, and the equipment automatically resumes operation when the water supply is insufficient; 4. When the user does not use water or the water consumption is very small, the non-negative pressure water supply equipment will automatically enter the shutdown and dormant state; When the water stabilized pressure tank cannot maintain the required pressure of the water supply network by the small flow pressure stabilizing pressure tank located on the outlet side of the equipment to maintain the water supply quantity and the leakage of the pipe network, the equipment will automatically wake up and resume normal operation. During the operation of the equipment, the remaining pressure of the water pipe network is fully utilized, which does not adversely affect the water pipe network and meets the needs of users to the greatest extent, reduces the energy consumption of water supply, and realizes the optimal operation of the water supply system.

1. The starting load is too large.

Cause: The outlet valve was not closed at start-up. Solution: Close the valve and restart.

2. The exhaust device is flooding.

Cause: Floating debris in the exhaust valve. Solution: Close the ball valve and open the exhaust valve cap to clean up the debris.

Hello, the water pump is broken, it will affect the normal flow of water circulation, which will cause the engine to be high, I hope it can help you

Answer: Hello, I'm glad to serve you, pro, pump failure may lead to engine failure, because the water pump is broken, it will directly affect the idle speed, resulting in unstable speed, and the speed will jump after the vehicle starts, and if the resistance is too great, it will cause the engine to stall. Leakage is a common fault, which will lead to a lack of coolant, which will cause symptoms such as high water temperature in the car and seriously affect the wear of the bearing. At the same time, you also need to pay attention to the following symptoms of car water pump damage

1. Unstable idling. The car water pump is connected with the belt, the cold water is pumped out of the water tank to cool the engine, if there is a problem with the rotation of the water pump, it will directly affect the speed of the engine, the phenomenon is the problem of unstable speed, usually in the engine start for a period of time, if the power is too large, it will turn off, from these phenomena can be preliminarily judged that the water pump is damaged.

2. Coolant leakage. This is a common fault, the engine is close to the pump part is prone to water leakage, at this time the coolant will leave a watermark in the pump ventilation hole, the lack of coolant engine will be "high fever", wear and tear will intensify, smoke or even fire in serious cases, at this time, the first thing to check the important parts of the cooling system (cooling fan, radiator, water pump, etc.) is damaged, do not drive reluctantly.

3. Noise problem. When the car water pump has signs of starting to break, it will show abnormal noise symptoms, and the cause of the noise is likely to be the internal bearing damage or the impeller is loose or out of the shaft to produce abnormal noise. At this time, it is necessary to pay attention to driving and overhaul the corresponding components in time, otherwise there will be a water pump strike, and the car engine will not be fully dissipated.
