Classification of pumps

Recommended Posts

    According to the different driving mode, the pump is generally divided into mechanical pumps and electric pumps. Most of the engines now use mechanical pumps, and electric pumps have been used in some newly developed, technologically high engines, such as the BMW 6-series (E63) engine.

1Mechanical pumps

    The mechanical water pump is driven by the engine crankshaft through the driving tape, and its rotational speed is proportional to the engine speed. The working methods of mechanical pumps have both advantages and disadvantages. When the engine is working under high speed and heavy load conditions, the heat produced by the engine, the high speed of the pump makes the circulating flow of the coolant increase, so that the cooling capacity of the engine can be improved. When the engine is working under low speed and heavy load, such as traction other vehicles or open air conditioner, the engine speed is low and the speed of pump is low. , which lowers the engine's cooling capacity.

2Electric pumps

    Electric water pump has brushless electric pump and brush electric pump. The electric pump is controlled by the engine control unit through the current, which is not affected by the engine speed, and can be flexibly operated according to the actual cooling of the engine. Because the electric pump consumes very little engine power, the fuel consumption of the engine can be reduced after the electric pump is used.

Hydraulic pump is connected with the prime mover, and the pump shaft has no additional radial load; while hydraulic motor is connected with the load, such as sprockets, pulleys, gears and so on, its main shaft will bear a higher radial load. 3. The low pressure chamber of the hydraulic pump is usually vacuum.

      Only you can protect your family or yourself from defective or noncompliant vehicles or equipment that could pose a threat to your safety.
      Hundreds of injuries have been reported, and 16 people have been killed in the U.S. by defective air bags that are part of the largest and most complex vehicle recalls in U.S. history—affecting tens of millions of vehicles from 19 automakers. Getting these unsafe vehicles repaired is integral to improving safety and saving lives. The U.S. Department of Transportation, National Highway Traffic Safety Administration (NHTSA) is urging vehicle owners to take a few simple steps to protect themselves and others from this urgent threat to safety. Learning how to check for recalls is the first important step, and the next is knowing how to get your recall fixed for FREE.
      What is a vehicle recall?
      A vehicle safety recall is just that—bringing an unsafe vehicle to a dealership to resolve a safety problem when a manufacturer or NHTSA determines that a vehicle or piece of equipment has a safety-related defect or does not comply with federal standards. Manufacturers are required to fix the problem by repairing it, replacing it, offering a refund, or in rare cases, repurchasing the vehicle. In 2019 alone, there were over 38 million vehicles recalled.
      Check for recalls
      If your vehicle is currently under recall, you should receive a notice in the mail from your vehicle’s manufacturer. If you’re worried about missing a notice, you can also stay up to date on recalls by
      link hidden, please login to view. You don’t need to wait for a notification to find out if your vehicle is under recall. Visit
      link hidden, please login to view and enter your VIN to see if your vehicle is under recall. You can also use NHTSA’s website to check on vehicle-related products, such as car seats, tires or equipment. Not sure where your VIN is? Look on the lower left of your vehicle’s windshield. It is 17 characters long. Your VIN is also located on your vehicle registration card, and may be shown on your insurance card too.
      Get the repair (for FREE!)
      If your vehicle is under recall, follow any interim safety guidance provided by the manufacturer and contact your local dealership to get the FREE recall repair.
      Report problems for investigation
      If you think your vehicle or equipment could have a safety defect, reporting it to NHTSA is important. If the agency receives similar reports from a number of people about the same product, this could indicate that a safety-related defect exists that would warrant an investigation. You can report any suspected safety defects to NHTSA one of two easy ways: by visiting

Vehicle owner reports fuel NHTSA’s work, and that’s why we’re committed to sharing more information with you about how to report recalls. NHTSA recommends checking your VIN twice a year to see if your vehicle is under any safety recall: when you set your clocks forward in the spring and when you set them back in the fall. Stay in touch with NHTSA and keep an eye on your mailbox for direct alerts. And if your vehicle is under recall, get it repaired for FREE immediately. With safer drivers and safer cars, we’ll have safer roads—and your efforts can help save lives.

    • OEM vs. Aftermarket Parts for Your Car: How to Choose
      When selecting parts for a car repair, it pays to know the differences between original and aftermarket parts. Whenever possible, get estimates for both.

      Choosing between original and aftermarket car parts — and even used parts of either type — is all about squaring your priorities with your budget.

      You’ll have different options depending on the part and the shop. And the best choice will depend on whether you’re trying to keep repairs cheap, restore your car’s appearance after a wreck or soup up your ride.

      Original equipment manufacturer (OEM) parts match those that came with your car, and are of the same quality as its original parts. They’re also the most expensive.

    • Replacement Intervals For Oil And Air Filters In Today’s Vehicles
      The factory-recommended replacement intervals for filters can vary quite a bit depending on the year, make and model of the vehicle, as well as how it is driven. As a rule, older vehicles (those more than 15 to 20 years old) typically have more frequent service intervals than newer vehicles. Why? Because late-model vehicles require less maintenance, thanks to improvements in motor oils, transmission fluids, engine design and filter media.

      Many long-life air and oil filters use synthetic fiber media or a blend of cellulose and synthetic fibers to extend filter life.

      Changing the oil and filter every 3,000 miles was standard practice decades ago. But it’s no longer necessary because most multi-viscosity oils today are a synthetic blend or a full synthetic that resist viscosity breakdown and oxidation for a much longer period of time. Late-model fuel-injected engines also run much cleaner than their carbureted ancestors, which reduces oil contamination in the crankcase.
