1. structure of Brushless DC water pump

The water pump used in the car is higher than the ordinary water pump in the structure and performance requirements: the working environment of the motor pump is poor, it should be able to prevent vibration, moisture-proof, heat resistant, especially for the stability of the pump, and the reliability of the water pump has higher requirements for the magnet rotor of the brushless DC centrifugal pump and the impeller. The rotor is in the middle of the rotor. The shaft sleeve is the direct injection molding shaft sleeve. The shaft sleeve is fixed in the rotor body with high endurance grinding graphite. The stator and the circuit board part of the motor are sealed in the pump body with epoxy resin adhesive. The stator and the rotor are a cavity. The pump cavity is connected with the rotor cavity of the motor. The rotor cavity of the motor is completely isolated from the motor stator and motor control. The rotating shaft is the rotating shaft. With high smooth, high strength zirconia finish, the shaft connects the motor with the pump body, without the traditional mechanical shaft seal, so it is completely sealed and the torque of the leakproof motor is produced by the magnetic field of the coil on the sand steel sheet (stator) to drive the permanent magnetic magnetic iron (rotor) to work. N (n is even) order magnetization of a magnet makes the parts of the magnet form a fully coupled magnetic system. When the magnetic pole produced by the stator coil is opposite to the magnetic pole of the magnet, that is, the displacement angle between the two poles is the lowest than that of the time magnetic system; when the magnetic pole rotates to the same pole, that is,The displacement angle between the two poles is 2 T / n, and the magnetic energy of the magnetic system is the maximum. After removing the external force, the magnetic poles of the magnetic system repel each other, and the magnetic force will restore the magnet to the lowest state of magnetic energy. So the magnet produces motion to drive the rotor rotation: the driving force of the brushless pump impeller is the brushless motor brushless DC pump through the electronic commutation, without the use of carbon brush, the magnet rotor and the stator sand steel sheet all have multilevel magnetic field, and the rotor will automatically change the direction of the magnetic pole when the rotor is rotated relative to the stator, so that the rotor is always kept in the same direction. It makes the stator and rotor of the brushless DC centrifugal motor pump completely isolated and completely avoids the liquid leakage of the traditional brushless DC pump. And it can be fully dive and completely waterproof, effectively improving the service life and performance of the pump, so the brushless does not need the lubricating grease of the pump bearing, and there is no seal pad and oil seal.

2. the brushed DC motor pump has a brushed DC motor pump, and the bearing of the pump shaft is lubricated by grease. Therefore, it is necessary to prevent the leakage of the coolant to the lubricating grease and prevent the leakage of the coolant. Water seal and gasket are used to prevent leakage of water pump. The water seal ring and shaft are fitted between the impeller and the bearing through interference, and the water seal static seal is tightly leaned to the shell of the pump, so as to achieve the purpose of sealing the cooling fluid, the magnet of the brushed DC centrifugal pump and the impeller are injected into the rotor of the motor. There are direct injection molding axle bushes in the middle of the rotor, through the high performance pottery. The ceramic shaft is fixed in the shell. The stator of the motor and some meter of the circuit board are sealed in the pump body with epoxy resin glue. There is a thin wall between the stator and the rotor, and it is completely sealed without the traditional mechanical shaft seal. The torque of the motor is through the coil on the sand steel sheet (stator) to generate magnetic field to drive the permanent magnet (rotor) to work. Its electromagnetic working principle is the same as the brushless pump motor. In short: brushless pump electronics commutation: brush pump motor is mechanical commutation: brush pump impeller drive is brush motor.

      2011 Chevy Equinox Water on back seat floor and trunk
      By chevyguy
      This car has nothing but issues, now I have water coming in when it rains and my back seat floor is a puddle. Took my spare tire out and have water in there also. Sprayed the whole car down and can see the water coming in when I spray the roof. Looks like it may be coming from the roof rack area. Took the panels off to look and the roof/body seal may be the culprit. Also found a bulletin on this. I ordered some 3M sealer on Amazon so I'll try and replace the seal. Anyone run into this on an equinox or terrain?

      How to Tell if Flood Water Has Damaged Your Vehicle
      By Auto News
      Severe weather, unprecedented rainfall and flooding have taken their toll on car owners. Many in the affected areas have driven through high water that may have damaged their vehicles. Even if your vehicle was not flooded or completely covered in water, the non-profit Car Care Council recommends that you follow these guidelines to check for damage due to water intrusion or contamination:
      Check interior carpets, upholstery and door and trim panels for dampness. If they are wet, the vehicle needs professional attention. If you simply let the carpet dry, it will quickly grow mildew and give off foul odors. Seat brackets, motors and modules should also be checked for rust and proper operation. Pull the engine oil and transmission fluid dipsticks and differential plug. If the fluid appears milky, diluted, is no longer its original color or is beige in color, then it is likely the pans contain water and the vehicle should be towed to your repair shop. Driving the vehicle with water present may damage the internal parts and require extensive overhaul or repairs. The council reminds motorists that some synthetic differential fluids may appear to be milky, but are not water contaminated. When in doubt, a professional automotive technician should make the evaluation. Check the air filter for water. If it is wet, replace the air filter and change the oil. Check the undercarriage, bumpers, radiator area and frame for mud, grass, dirt, debris and rust. If any of these are present, the vehicle should be washed and cleaned as soon as possible. Have the brake system checked by a professional automotive technician. Check the exterior lights for moisture and water. Replace headlights and bulbs that contain water. Listen for abnormal noises while the engine is running. Make a note of where the noise is coming from and take the vehicle to a professional automotive technician as soon as possible. Have the suspension joints lubricated, if necessary. Many newer vehicles are lubricated at the factory for life; however, these joints should be checked for rust. “It all comes down to how much water the vehicle took in and where it reached,” said Rich White, executive director, Car Care Council. “By being car care aware and following these simple guidelines, you can help minimize the potential for damage to your vehicle.”
      The Car Care Council is the source of information for the “Be Car Care Aware” consumer education campaign promoting the benefits of regular vehicle care, maintenance and repair to consumers.

      Improvement of water pump
      By 袁春凤 (Tiffany)
      The most important component of the water pump is the pump shell and the inner parts of bearing and the bearing. To improve the pump, the most important thing is to optimize and improve the two parts. The following is a detailed introduction to the improvement of the two parts.
      1. to improve the pump shell. When disassembly the pump to inspect the failure, there are a large number of debris seriously affect the quality of the pump and work efficiency. In this case, we can reduce the two holes used for drainage on the pump shell to one, and remove the drain holes on the upper part of the transmitter. This can greatly reduce the small particles and sundries into the pump, thus greatly reducing the interference of sundries on the pump and the other bad.
      2. to improve the bearing. In the case of the failure of the bearing, we are generally sealed, the lubricating oil used by the bearing, the ball of the bearing and the bearing itself. So we should have a solution to these parts
      3. to improve gasket. The traditional design is to design the sealing test as a double mouth seal, so the advantage of the design is that two ports are all frictional with the bearing, the roughness of the bearing surface is more appropriate and the wear of the lip is relatively slow; but the disadvantage is that a large amount of dust can be directly entered into the middle of the mouth and bearing, so that the plate will be used for a period of time. The interference between the bearing and the bearing decreases, thus losing the original function of the seal. There are two ways to improve it: the first is the sealing week of the bearing with double, and the sealing area is lengthened properly and the thickness of the chip mouth is thickened accordingly. The method is to change the original double mouth into the three form of the seal and seal the seal. The advantage of this structure is that the outer lip and mouth have increased the seal design, which can resist many dust. However, this method also has shortcomings, the mouth and the reverse cap friction, the surface roughness of the surface of the cover is relatively poor, it is very easy to wear and tear seal test, resulting in sealing failure.
      4. to improve the lubricating oil. The bearing of the automobile pump is a more special bearing unit. Its environment is mostly temperature, humidity and dust, and the temperature of the water usually reaches about one thousand degrees, so the lubricating oil of the bearing is required. From our analysis of the fault, the lubricating oil in the bearing of the fault appears discolourable, which means that the grease in the lubricating oil is not enough, so the lubricating oil manufacturer should be required to increase the fat content of the lubricating oil so as to ensure the better protection of the bearing.
      5. to Improve the contact ball of the bearing. Balls in bearing are important parts to ensure normal operation of bearings, but there are more and more damage to rolling balls. When measuring the hardness of the ball, it is found that most of the balls do not meet the required hardness requirements, which makes the bearings greatly wear at high speed and finally breaks down completely. Therefore, we should strictly supervise the production quality of the manufacturers, guarantee the hardness of the ball and pass the quality, so that the fundamental problem of bearing damage can be effectively solved.
