Abstract

The utility model belongs to air compressors, in particular to a single screw type air compressor for a locomotive. The single screw type air compressor comprises a motor (1), a motor terminal box (1-1), an electric control box (7), a centrifugal fan (2), a connecting sleeve (4) and an air suction pipe (3-1), a cooler (12) is arranged on the lower surface of the air compressor, an oil-gas separator (15) is arranged above the cooler (12), the left side of the upper surface of the oil-gas separator (15) is connected with a temperature control valve (17) and the cooler (12) by using an oil pipe (16), the upper end of the temperature control valve (17) is connected with a machine oil filter (18) and the lower end thereof is connected with the oil-gas separator (15) by using the oil pipe (14), and the motor (1) above the oil-gas separator (15) is connected with the centrifugal fan (2) and is directly connected with a single screw compressor (6) through the connecting sleeve (4). The single screw type air compressor for the locomotive is suitable for the frequent startup of the locomotive, the service life can achieve 10-15 years, and the single screw type air compressor has simple structure, force balance and high efficiency.

Description

Locomotive single screw type air compressor

Technical field

The utility model belongs to air compressor, a kind of especially locomotive single screw type air compressor.

Background technique

At present, railway locomotive does not still have the single screw type of employing air compressor, and what majority used is piston type and double-screw type air compressor, these two kinds of air compressor structure more complicated, and the processing technology difficulty is big, the cost height, and also efficient is low, is subjected to force unbalance.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned technical deficiency, and a kind of simple in structure, stress balance, efficient height, long locomotive single screw type air compressor of life-span are provided.

The technological scheme that the utility model technical solution problem adopts is: locomotive comprises motor with the single screw type air compressor, connection box for motor, electric control box, centrifugal blower, connecting sleeve, sucking pipe, be characterized in below air compressor, being equipped with cooler, deaerator is equipped with in the cooler top, the last left side of face of deaerator connects thermostat valve and cooler with oil pipe, thermostat valve upper end junctor oil strainer, the thermostat valve right side connects the gas control oil cut-off valve, the lower end connects deaerator with oil pipe, the motor of deaerator top connects centrifugal blower and process connecting sleeve and single screw compressor direct connection, the centrifugal blower top is an air filter, air filter connects sucking pipe one end, the sucking pipe the other end connects single-screw air compressor, thermal switch is established in the air compressor top, electric control box is established in the left bottom, the main exhaust pipe is established in the lower right, and pouring orifice is established in the deaerator upper right, and vibration damper is equipped with at two ends, deaerator below.

The beneficial effects of the utility model are: locomotive is fit to the locomotive frequent starting with single screw type pneumatics function, can be under the rugged environment of big temperature range reliable operation, can reach 10～15 years working life, simple in structure, the stress balance of single screw type air compressor, efficient height.
