A CAMSHAFT: MEASUREMENT AND ANALYSIS | MIKRO - 0 views

  •  
    A camshaft plays like a timing device that manages the opening and closing of the ingestion and depletion valves and also fixing the valve overlap that performs at top dead center on the exhaust stroke. The shaft is built with numerous journals which ride on comportments inside the engine. It has egg-shaped lobes that stimulate the valve train, either by the moving pushrods and lifters or by pushing straight on valve stems. The camshaft is constrained to crankshaft turning by chain's timing, timing belt or timing gears, and the failures in camshaft drive can permit the valves to interact the piston crowns, that cause widespread internal destruction. The Additional Camshaft Functions: The camshafts in mature engines may also have gears automated into them that execute the distributor and the oil pump. For modern engines, the camshaft may have a situation sensor attached to the end that transfers data to the powertrain control unit to help the module right time your fuel injection pulsations and ignition. Some engines can have several camshafts, like with some overhead cam machines, mainly ones built in a "V" structure. Engines that have a desmodromic valvetrain use minimum 2 cams, as there is 1 push-open cam and 1 pull-close cam, in place of the classic push-open cam along with valve springs to pull the valve shut as the cam revolves past the lobe and back on to the circle base. The Camshaft Measurement: Entire lobe measurement, graphic presentation and lift analysis, acceleration, velocity, bump (3rd derivative) radius of curving, angle's pressure Lobe data modified and brought to zero base circle run-out Camshaft can have Angular position listings for all lobe tip angles It can be equalled measured data and design lift data profiles in numeric and graphic modes Screen graphic presents for all motion curvatures You will be accessible to printed reports of tabular data and screen graphics Compare base circle radius, run-out, and lobe tip angles to d

LEAK TESTING OF ENGINES | Mikro Blog - 0 views

  •  
    The heavy and bulky machinery in the industries requires right amount of check and scrutiny for the performance they give resulting to productivity. For continuous efficiency without barriers and obstacles, such high-quality machines need to be verified in a proper manner by some of the trusted familiar methods in the industry. There can be numerous types of defects found in the industrial machinery by the course of time and performance over the years. One such type is leaks which can later be proved dangerous if not checked occasionally. Leak test is done on the industrial engines and machinery to verify the presence of leaks in a device or component. It is basically a non-destructive technique that corrects the performance of the equipment for raising its output, efficiency and lifespan. Mikro Innotech India deals in manufacturing of the high-quality and efficient testers to be used for the following verifications: Mechanized machines and semi-mechanized or manual bench gauges Mechanized assembly lines, leak tests and/or dimensional checking There are some usual checks by the leak testers, they are as follows: Oil Circuit Leakage Fuel Circuit Leakage Gasket Leakage Water Circuit Leakage A leak tester is specialized for verifying and checking the following parts: An Engine Block Crankshaft & Camshaft Cylinder Head Differential Gearbox Gear Case Steering Gearbox Sleeves and All types of Valves An engine, when runs on miles, requires a good amount of power that might be lost because of the piston ring, cylinder wall wear or valve. This directly affects the engine's performance and needs leak tester and air leak tester to check. The following process named as Engine Leak Testing then becomes handy for further assessment: The Engine Pressure Reading: A general test of an engine's capability to compress the air-fuel combination is an engine compression check. A pressure gauge is attached to spark plug place. The engine is then activated to produce a pressure r
