Points for attention to replace pumps

Recommended Posts

When the pump is damaged, we should pay attention to the following items when replacing.

(1)   The real cause of the pump damage should be clear. Before replacing the pump, the radiator fan, thermostat and coolant should be determined.

(2)   It is likely that pumps with similar shapes but suitable for different types of engines will occur, so before installing the pumps, a comparison should be made between the new pump and the old pump removed, or a check should be made on the part number of the pump and the type of the engine to determine whether the selected pump is suitable for the model being repaired.

(3)   Water pump installation surface should be carefully cleaned and leveled.

(4)   When installing the pump, wet the seal ring with coolant first. If you need to use sealant, be careful not to apply too much.

(5)   Do not use the way of percussion pump shaft to install the pump. You should check the real reason for the difficulty of pump installation. If the excessive scale in the cylinder water channel leads to the difficulty of pump installation, steel wire brush or fine sand paper should be selected according to the scale situation. When installing bolts in water pumps, they should be tightened progressively in the direction of diagonal according to the prescribed torque, excessive tightening of bolts or causing damage to gaskets.

(6) The tension of the pump belt must be strictly controlled according to the adjustment standard. Excessive tension of the belt, will cause bearing overload operation and early damage; and too small tension, easy to produce noise, serious pump can not work properly.

Feilong Jiangli warm notes: If you can't replace it by yourself, please go to the warehouse.

      link hidden, please login to viewSevere 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 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.

    • 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.

      China's shortcuts in automobile manufacturing industry
      Over the past nine years, China has become the world's largest automobile market and producer, with annual production and sales exceeding 25 million vehicles. China's automotive industry has also been the world's largest automotive industry in just a few years, driven by the huge domestic demand of the Chinese market. But there is not a strong enough component system to support the development of China's automobile industry. In March this year, the 2017 Top 100 list of global auto parts suppliers was officially unveiled. Unsurprisingly, Germany's Bosch Group continued to rank first with more than $46 billion in revenue, while German gearbox supplier Zeiff rose to second. From the third to the tenth ranking of parts companies are Magna, electronics, mainland, Aixin, modern Mobius, Virginia, Lear.
      In this ranking, China's highest ranking of parts companies is Yanfeng automotive interior system, followed by CITIC Deka ranked 71. And the selected parts enterprises are mainly single components. Feilong Jiangli supply water pumps for car plants.
      In contrast, there is no comprehensive automobile parts supplier in China's automobile industry.
