Adult electric motorcycle: the future or a fad?

图片
   Look around any motorcycle showroom and you'll notice one thing: every motorcycle uses the same basic technology to function. That is, until now. As technology has evolved, motorcycles have not been affected by such innovations to a large extent. However, the motorcycle industry has experienced a belated upgrade in the form of adult electric motorcycles. Whether adult electric motorcycles will become the new normal remains to be seen. There are many pros and cons to adult electric motorcycles, and it mostly comes down to personal preference as to which riding experience suits your preferences. But for the savvy, forward-thinking rider, electric bikes are the future.  The Benefits of   a dult  e lectric  m otorcycle : There's a reason motorized vehicles have adopted electric features. The benefits of adopting electric technology aren't just good for the environment: they're good for the rider, too. These benefits include :   ( 1 ) Save time: Spend mo...

Electric scooters vs gas scooters - which one to choose?

图片
   Two-wheeled vehicle technology has made tremendous strides in the past few years. While the market continues to be dominated by gasoline scooters, the introduction of  electric scooters   has provided potential customers with a range of two-wheeled vehicles to choose from.   So, when it comes to buying your two-wheeler if you had to choose between an electric scooter and a gasoline scooter, which one would you choose?   A quick comparison will help you make an informed decision.   1. Pricing. Electric scooters are more expensive than the more affordable gasoline versions, so going green comes at a high price. Some of the highest-rated electric scooters use expensive lithium-ion batteries. However, the Indian government is trying to promote the adoption of electric scooters, so it has capped the incentive at Rs. 15,000 per kWh, which covers almost 40% of the total cost of a two-wheeler.   Gasoline scooters best serve the interests of customers w...

How to Find Elbow Center of Pipe?

图片
   If the elbows in your pneumatic conveying system need to be replaced due to wear or abrasion or if you’re designing a new layout for your system, correctly measuring your existing elbows to ensure you order the right size is key.   For standard degrees of pipe elbows such as  45° pipe elbows   and  90°pipe elbows , elbow center to end dimensions are available in standard pipe charts. But many times, custom elbow angles are required at site which should be cut from standard 45° or 90° elbows.   The formula for calculating the center to end distance of such elbows is as follows: Elbow length in mm = Tan(Elbow Angle/2)Elbow Radius in mm   For 90° Long Radius elbows, the center to end dimension given in dimension tables of ASME B16.9 is the same as the radius of the elbow. This is because Tan(90/2) i.e. Tan 45 is 1. Normally custom elbow angles from 45 degree to 90 are cut from 90 degrees standard elbow. But for custom...

Why choose cast iron fittings?

图片
  Cast iron is both reliable and durable, making it the best choice for use in commercial buildings. Cast Iron Pipe Fittings   Cast iron pipe and fittings have been the backbone of drainage, drainage and ventilation piping systems around the world for centuries.   While plastic meets minimum building standards in many cases, what meets code and what represents the best solution for high-performance commercial construction are two very different issues.   Many times, the cost advantages of plastics over cast iron are not what they appear to be. Before allowing a job to be converted to PVC or ABS, consider five areas that may add cost and complexity.   Fireproof construction Underground installations Above-ground installations Sound attenuation Importance of manufacturing standards   Cast Iron Types   Cast iron soil pipe and fittings fall into two main types - hub and socket and hubless. Hubless pipes and fittings are also referred to as hubless in the p...

Selecting Piping and Piping Materials

图片
  Many factors are involved in selecting piping and piping materials. Designers should approach these decisions and determine the advantages and disadvantages of various piping materials and connection methods.   Today we will discuss together on the following topics. Understand the advantages and disadvantages of various piping materials. Become familiar with some of the issues associated with material compatibility. Understand corrosion issues in circulating and domestic piping systems.   The piping material chosen depends on the application and water quality. For example, heating systems typically use steel pipe because of its low cost, high strength and heat resistance, while pure water systems may use pure polypropylene (PP) or polyvinylidene fluoride (PVDF) pipe. Basic material characteristics   Steel is strong, rigid and has a low coefficient of thermal expansion. It is also heavy (may require multiple workers to transport) and prone to corrosion. It is someti...

What Is Ultrasonic Testing Equipment?

图片
   Ultrasonic Testing  (UT)  is a branch of NDT technology that involves the emission of high-frequency acoustic energy or ultrasound into an asset for corrosion mapping, obtaining data/measurement, or identifying cracks or defects. There are three basic components included in UT.   Pulse generator/receiver: a device that emits ultrasound waves/pulses Transducer: driven by the pulse, the transducer produces high-frequency energy which is sent to the asset in the form of a wave. When a discontinuity or defect is detected in the wave path, the energy is reflected and converted by the transducer into an electrical signal. Data display/visualization: After the transducer has converted the electrical signal, the data is displayed on a screen for analysis by the control inspector.     HS 811 TOFD Flaw Detector UT offers many advantages over other types of NDT, including but not limited to a safe speed, ease of use, and accuracy for the inspector.

How to choose an oil filter?

图片
   Owners often receive conflicting advice on what to say about oil filters. Owner's manuals, installers, quick lube operators, mechanics  , and retail store personnel all have different opinions. The truth is that when it comes to oil and filters, the only correct answer is the one that varies from situation to situation. People are different. Driving conditions are different. A one-size-fits-all approach does not apply to oil filters. So it's up to us to choose an oil filter that is right for the situation.   What are the reasons for choosing an oil filter? An oil filter,  is  also known as an oil compartment. Here's what it does: When your engine burns fuel, it produces harmful byproducts such as sludge, chemical toxins  , and ash, which can cause engine damage. The oil suspends these contaminants and passes through the oil filter, removing this debris from the oil to protect your internal engine parts from premature wear, and to protect the interna...

10 Factors to Consider When Choosing the Best Engine for a Semi-Truck

图片
   1. Type of work First, as an owner-operator, you need to know what type of work you will be doing, e.g., average load weight The type of terrain you will be traveling over The type of trailer you will be pulling Know the specifications of the rest of the drive line Know what transmission and rear differential ratios   2. Size considerations Bigger is better is somewhat of an outdated idea of thinking about the best truck engine. Bigger horsepower is best, which doesn't sound as true now as it used to. Depending on the type of work you will be doing, bigger isn't always the   best choice for a truck engine . I suspect there used to be more androgyny involved in many engine choices. Since owner-operators are in business for profit, rather than bragging about their rights at the truck stop counter, the "smaller" engines (13 liters) are much better now than they used to be. Most of these diesel engines can reliably reach 500 horsepower at 1850 TQ, which is a pretty im...
