Abstract

The utility model provides a turbine pressure booster, which mainly comprises a main shaft, a gas compressor, a shell and a turbo machine, wherein two ends of the main shaft are respectively connected with a shaft of the gas compressor and a shaft of the turbo machine, the main shaft is installed inside the shell through a bearing, and the outer side of the bearing is provided with an oil tight, and the utility model is characterized in that a cooling water passage, a water inlet and a water outlet are arranged inside the shell, and the upper and the lower walls of the shell are respectively provided with an oil filling port and an oil discharging port, which lead to the inner cavity. The turbine pressure booster has the advantages that the pressure booster is unrelated to the pressure of the lubricant oil, and the oil is free from containing carbon, so the accidents such as inadequate supply of the oil, no oil supply and the burning loss of the bearing can not occur.

Description

A kind of turbosupercharger

Technical field

The utility model relates to turbosupercharger.

Background technique

Existing vehicle turbocharger utilizes the waste gas of motor to promote the turbine rotation, and turbine shaft drives the gas compressor rotation and produces supercharging, uses the circulator oil-lubricated bearing, simultaneously cooling bearing; But because engine oil pressure is low, the fuel feeding deficiency, machine oil meets the easy carbon deposit of high temperature, causes to run out of oil, makes bearing by scaling loss, if the pressurized machine pipeline leak, also can the scaling loss engine crankshaft, bearing shell etc.

Summary of the invention

The purpose of this utility model is to provide a kind of water-cooled turbosupercharger.

The utility model provides a kind of turbosupercharger; mainly comprise main shaft, gas compressor, housing and turbo machine; the main shaft two ends are connected with the axle of gas compressor and the axle of turbo machine respectively; main shaft is contained in the housing by bearing; there is oil sealing in the bearing outside, it is characterized in that: cooling water channel, water intake and water outlet are arranged in the housing, have oil filler and fuel outlet towards inner chamber on the housing on the lower wall; lubricant oil also is subjected to the protection of cooling water, in order to avoid the high temperature carbon deposit.

The turbosupercharger that the utility model provides, the axle of its gas compressor and/or the axle of turbo machine can be made one with main shaft, to reduce link, reduced volume.

The turbosupercharger that the utility model provides, its advantage is: irrelevant with lubricating oil pressure, do not have carbon deposit in the machine oil and cause the fuel feeding deficiency, run out of oil, bearing is by a series of accidents such as scaling loss.
