Problems solved by technology

[0004] Some of the oil pumps in the existing oil supply devices use gear pumps, but the gear pumps have the problems of unbalanced radial force, large flow pulsation, too much noise, low efficiency, and serious leakage of lubricating oil during operation; Horizontal three-screw pump, when this pump is running, it has strong self-priming ability, uniform and continuous flow, small vibration, low noise, almost no wear, and long service life. The connection part of the coupling adopts a mechanical seal, which cannot achieve zero leakage. Especially when the coupling is poorly processed and assembled, oil leakage occurs just after the horizontal three-screw pump starts to run, polluting the site environment

Abstract

The invention discloses an oil supply device without oil pump oil leakage for a turbo expander. The oil supply device comprises an oil pump and an oil tank, wherein the oil pump is connected with a motor through a coupler, and the oil pump and the coupler are arranged in the oil tank. According to the oil supply device without oil pump oil leakage for the turbo expander, the oil pump and the coupler are arranged in the oil tank together, so that the oil suction effect of the oil pump is better, the phenomenon that the oil pump leaks oil outwards is thoroughly avoided, pollution to the environment is eliminated, the purposes of energy conservation, emission reduction and environmental protection are achieved, and meanwhile the use cost is saved.

Description

technical field [0001] The invention relates to an oil supply device for an oil pump used in a turbo expander without oil leakage. Background technique [0002] The turboexpander is the key single unit in the air separation equipment, it provides almost all the cooling capacity in the air separation equipment, its performance directly determines the energy consumption and reliability of the air separation equipment; currently in the air separation equipment, the matching Most of the turbo expanders are lubricated by oil bearings. This turbo expander has the advantages of convenient operation, stable operation, large bearing capacity, and is suitable for various operating conditions. It needs a set specially designed for bearing oil supply. The purpose of the oil supply device is to provide clean lubricating oil with a certain pressure, temperature and oil volume for the bearing. [0003] The oil supply device is generally composed of an oil pump, an oil tank, an oil inlet f...
