Description
Exhaust-driven turbo-charger exhaust-gas turbo charger energy-saving type delivery test device of the present utility model belongs to diesel exhaust turbocharger test technology.
In the prior art, the delivery test device of diesel exhaust turbosupercharger as shown in Figure 1.It through air intake valve ［ 2 ］, with an amount of pressurized air, is blown into the turbine ［ A ］ of tested supercharger ［ 4 ］ by firing chamber ［ 3 ］ by electronic wind regime pneumatic plant ［ 1 ］, drives supercharger ［ 4 ］ running, and does cold blowing break-in or igniting.At this moment the pneumatic plant ［ B ］ of supercharger ［ 4 ］ sucks air through flow measurement orifice plate ［ 5 ］ and air cleaner ［ 6 ］, and the air that its pneumatic plant ［ B ］ extrudes is through vent valve ［ 7 ］, and markon's land used does not drain into atmosphere.Behind the cold breaking in, turn down gas admittance valve ［ 2 ］, make air quantity be fit to firing chamber ［ 3 ］ fuel feeding igniting.At the beginning of catching fire, drive big gas admittance valve ［ 2 ］ earlier, to prevent turbine ［ A ］ inlet gas overtemperature, after treating that supercharger ［ 4 ］ rotating speed rises, progressively close air intake valve ［ 2 ］, air release ［ 7 ］ once more, open self-loopa valve ［ 8 ］, cut off wind regime pneumatic plant power supply, realize and the car self-loopa.This test unit adopts the bigger Root's blower of capacity to make the wind regime pneumatic plant usually, its structure heaviness, and noise is big, needs to be equipped with sound suppressor, investment is big thereby the price height makes test unit, and occupation of land is many.
The purpose of the present utility model is: a kind of exhaust-driven turbo-charger exhaust-gas turbo charger energy-saving type delivery test device is provided, and it uses the technology of starting supercharger in the afterburning super high pressure-charging diesel engine with the differential pressure pneumatic plant, replaces the wind regime pneumatic plant, realizes the supercharger delivery test.This device can be finished the delivery test task, and is light and handy again, small-sized, energy-conservation, noise is low, is suitable for practicality for utilization, the repairing department of supercharger provides a kind of, reduces investment outlay, energy consumption is low, can guarantee the test unit of repair quality.
Exhaust-driven turbo-charger exhaust-gas turbo charger energy-saving type delivery test device of the present utility model, it is made up of firing chamber, differential pressure pneumatic plant, drive motor, synchronous transmission device, self-loopa valve, flow measurement orifice plate, air cleaner, tested supercharger and various connecting line, and its key is: the air-breathing electric butterfly valve of a bypass is housed on the connecting line between the blower outlet of differential pressure compressor inlet and tested supercharger.
Exhaust-driven turbo-charger exhaust-gas turbo charger energy-saving type delivery test device of the present utility model, because the negative pressure that the differential pressure pneumatic plant produces, air is mended into, the flow of tested booster turbine greater than the flow of pneumatic plant through the air-breathing electric butterfly valve of bypass, helps realizing under higher rotation speed energy equilibrium therebetween; Test unit drains into atmosphere with the air that tested supercharger air compressor extrudes in the prior art owing to having avoided, and makes full use of its energy and send into the differential pressure pneumatic plant, has significantly saved the power consumption of differential pressure pneumatic plant.Replace the bigger wind regime pneumatic plant of former test unit capacity with the differential pressure pneumatic plant, both reduced the capacity of former drive motor, saved equipment investment again, reduction noise, minimizing are taken up an area of and then are realized test unit compactness, light and handy, small-sized, energy-conservation, and noise hangs down the purpose with reduced investment.Compare with the prior art of differential pressure pneumatic plant starting supercharger with quilt combustion super high pressure-charging bavin pool machine, the air-breathing electric butterfly valve of bypass that increases, guaranteed that the differential pressure pneumatic plant drives the required air mass flow of tested supercharger, satisfies the requirement of cold blowing break-in of supercharger delivery test and igniting.

Accompanying drawing 2, exhaust-driven turbo-charger exhaust-gas turbo charger energy-saving type delivery test device
Exhaust-driven turbo-charger exhaust-gas turbo charger energy-saving type delivery test device of the present utility model, embodiment as shown in Figure 2.Test unit is made up of firing chamber ［ 3 ］, differential pressure pneumatic plant ［ 9 ］, drive motor ［ 11 ］, synchronous transmission device ［ 12 ］, self-loopa valve ［ 8 ］, flow measurement orifice plate ［ 5 ］, air cleaner ［ 6 ］, tested supercharger ［ 4 ］ and various connecting line.Key of the present invention is, for guaranteeing that air capacity that differential pressure pneumatic plant ［ 9 ］ is produced can satisfy the needs of tested supercharger ［ 4 ］ cold blowing break-in and igniting, on the connecting line between pneumatic plant ［ B ］ outlet of ［ 9 ］ import of differential pressure pneumatic plant and tested supercharger ［ 4 ］, install the air-breathing electric butterfly valve of a bypass ［ 10 ］ additional.According to the test needs, adjust the running in speed and the air capacity of the tested supercharger of butterfly valve ［ 10 ］ aperture scalable.
Firing chamber in the device ［ 3 ］ can adopt aeromotor to use the firing chamber; The optional electric butterfly valve of using of self-loopa valve ［ 8 ］; Differential pressure pneumatic plant ［ 9 ］ can adopt the major diameter centrifugal-flow compressor that pressure ratio one discharge characteristic is more smooth, efficient is higher, by motor direct-drive; Present embodiment employing and tested supercharger ［ 4 ］ are with supercharger a series of, that flow is bigger, getting its pneumatic plant uses, and assemblies such as the turbine disk on the supercharger, nozzle ring and gas inlet shell are removed, add in turbine end and load onto synchronous transmission device ［ 12 ］, drive by drive motor ［ 11 ］; Drive motor ［ 11 ］ can adopt high-revolving interchange or direct current motor; Synchronous transmission device ［ 12 ］ should be used the higher odontoid belt transmission of linear velocity, connects with differential pressure pneumatic plant ［ 9 ］ by non-contact magnetic force driving device.
The pneumatic plant ［ 8 ］ of tested supercharger ［ 4 ］ sucks fresh air and measures air mass flow through air cleaner ［ 6 ］ and flow measurement orifice plate ［ 5 ］.
Exhaust-driven turbo-charger exhaust-gas turbo charger energy-saving type delivery test device of the present utility model is when on-test, driving differential pressure pneumatic plant ［ 9 ］ by drive motor ［ 11 ］ by synchronous transmission device ［ 12 ］ earlier rotates, the flow through pneumatic plant ［ B ］ of tested supercharger ［ 4 ］ of its inhaled air, between the import and export of pneumatic plant ［ B ］, produce a differential pressure, order about pneumatic plant ［ B ］ and rotate.Meanwhile, ［ 3 ］ promote turbine ［ A ］ rotation of tested supercharger ［ 4 ］ to the pressurized air of pneumatic plant ［ B ］ outlet through the firing chamber by pipeline, driving pneumatic plant ［ B ］ simultaneously is rotated further, reaching a certain lower stationary value until supercharger ［ 4 ］ rotating speed no longer raises, open the air-breathing electric butterfly valve of bypass ［ 10 ］ then gradually and replenish the suction fresh air, increase air mass flow, continue to drive turbine ［ A ］ rotation of tested supercharger ［ 4 ］, rotating speed rises, until reaching required higher cold grinding rotating speed.After the cold grinding running, firing chamber ［ 3 ］ fuel feeding igniting is closed the air-breathing electric butterfly valve of bypass ［ 10 ］ gradually and is opened self-loopa valve ［ 8 ］ simultaneously, cuts off the power supply of the drive motor ［ 11 ］ of differential pressure pneumatic plant ［ 9 ］, delivery test is carried out in supercharger ［ 4 ］ and car self-loopa.
The utility model is through joining the machine evidence, owing to adopt differential pressure compressor ［ 9 ］ to replace the wind regime compressor ［ 1 ］ of larger capacity, device power consumption and volume reduce at double, the advantage such as have energy-conservation, compact, miniaturization, noise is low, equipment investment is few. Pilot project reaches the delivery test specification requirement, both has been suitable for practicality, has reduced investment outlay, and has again good economic benefit and social benefit.
