Abstract
The utility model provides an ideal supercharger pressure measuring instrument for supercharged engine in the technical field of engine. The instrument is characterized in that three interfaces of the three-way hollow splitter are respectively connected with a branch pipe of engine intake pipes pressed in by a compressor of the supercharger, an oil pump and a pressure measuring meter. The pressure measuring meter of the instrument can be installed in an operating room. The pressure can be measured as soon as the pressure measuring meter is connected without dismounting the oil pump of the supercharger in examination. Scientific datas of superchargers, engines, automobile industry and maintenance can be measured according to different requirements. The utility model has the advantages of no dismounting, labour saving and time saving.
Description
Technical field:
The utility model belongs to technical field of engines, specifically is a kind of engine with supercharger supercharger gas-pressure survey meter.
Background technology:
The automobile of existing engine with supercharger, steamer, engineering machinery etc., when work when supercharger, when oil pump goes wrong, the operator can't find, thereby in the time of can making full engine load, the air pressure of supercharger is higher than setting, makes cylinder detonation, temperature height, increased pressure, mechanical load big, easily towards head gasket, damage cylinder cap, wearing and tearing cylinder barrel, piston damage bent axle, connecting rod.Oil pump feed is excessive, and discharging exceeds standard.Oil is chewed and is burnt to death.Supercharger rotor assembly hypervelocity, fatigue is scrapped.When supercharger air pressure was lower than setting, the supercharger noise was big, surge, shake, shook bad engine and supercharger part.Because pilothouse does not install and measure the instrument of supercharger, oil pump air pressure, the driver can't find above-mentioned fault.Another kind of situation is when the engine of automobile, steamer, engineering machinery has fault to repair, fault to supercharger, oil pump, engine three is obscured easily, be not easy difference, particularly supercharger is owing to can't detect, can only adopt its other parts of replacing to grope to repair, or the replacing complete machine, cause very big waste.Generally speaking, all to overhaul in detail the three, time-consuming, to take a lot of work, waste is big, and each car is spent more 1-2 ten thousand costs of repairs every year.
Summary of the invention:
The objective of the invention is to design a kind of supercharger that detects, need not to dismantle the measuring instrument that can detect the engine with supercharger supercharger.
For reaching above-mentioned purpose, the main technical schemes that the utility model is taked is: go out threeway hollow splitter according to the gas dynamics principle design, an interface of threeway hollow splitter is connected with the branch bronchus that the pneumatic plant of supercharger is pressed into engine air inlet tube, another interface is connected with the complemental air air intake opening of oil pump, the 3rd interface is connected with rain glass, thereby constitutes a kind of engine with supercharger supercharger gas-pressure survey meter.
The rain glass of the supercharging gas engine supercharger gas-pressure survey meter that the employing such scheme is made can be contained in the pilothouse, at any time grasp the air pressure of supercharger for the driver, understand the duty of supercharger and oil pump, do not dismantle when also but the repairman overhauls supercharger, oil pump, on engine, measure, repair.Because the threeway hollow splitter that is provided with can be pressed into supercharger air compressor the air branch of compensator dexterously, a part enters in the compensator diaphragm chamber, another part is in air flue enters rain glass, the air pressure number that the rain glass of this gas-pressure survey meter records, being exactly the air pressure of supercharger, also is the air pressure that oil pump increases oil, if this air pressure is higher than setting or is lower than setting, it directly influences the power of engine, damages each parts of engine when serious.The engine operation normal condition is: rated engine speed---supercharger 100,000 turn left the right side-----oil pump ratch stroke increases 4-5mm---enter engine single cylinder fuel oil and increase by 2～4ml---, and engine capacity increases by 20～30% to produce air pressure 0.1Mpa.Need not dismantle on engine when measuring instrument detects supercharger, oil pump, the time and labour saving was surveyed in 10 minutes.Provide science data according to different needs to manufacturing, use, maintenance, the measurement of supercharger, engine, automobile.The blank that China's automobile, steamer, engineering machinery driving cabin instrument are measured automatically to supercharger, oil pump has been filled up in its appearance, survey inspection air pressure during for supercharger, oil pump, engine manufacturing, maintenance science data and advanced method are provided, give and on engine, not dismantled supercharger from now on, oil pump carries out barometric surveying, maintenance, has started the new situation.
