Problems solved by technology

[0003] The fuel tank of the existing online decentralized hydraulic station often uses a refueling trolley to replenish oil. If a sudden leakage occurs in the hydraulic system, in addition to repairing the leak, sometimes the fuel tank of the online dispersed hydraulic station must be replenished to resume production.
However, it takes a long time to refill the oil tank of the online decentralized hydraulic station with a refueling trolley, because oil product transfer, refueling trolley transfer and electrical wiring, etc., must invest a certain amount of manpower and take a certain amount of time to complete the refilling of the online decentralized hydraulic station fuel tank. oil, too long oil replenishment time will have a great impact on production
[0004] In addition, there is also an oil replenishment system that uses the oil tank of the fixed-point pump room to transport the hydraulic oil to the oil tank of the online decentralized hydraulic station through the pump. However, this oil replenishment system has a large investment and high fire safety requirements.

Abstract

The invention discloses an online decentralized hydraulic station oil tank centralized oil supply system and an online decentralized hydraulic station oil tank centralized oil supply method. The oil supply system comprises an online large hydraulic station oil tank, a plurality of ball valves, a shock absorber throat, a screw pump motor group, a one-way valve, a pressure gage, a filtering device, a cooling device, a spare oil drum, a pressure measuring adapter and a pressure measuring hose, wherein the parts are connected to form the online decentralized hydraulic station oil tank centralized oil supply system through pipelines and adapters. Centralized oil supply to the system comprises oil supply to the large hydraulic station oil tank and oil supply to a decentralized hydraulic station oil tank through the large hydraulic station oil tank; in the process of supplying oil to the large hydraulic station oil tank, ball valves on the sides of various decentralized hydraulic station oil tanks are closed, an oil absorption hose is inserted into the spare oil drum to absorb oil, and when oil is up to the liquid level, a second ball valve is closed, and a first ball valve is completely opened; and in the process of supplying oil to the decentralized hydraulic station oil tanks, a third ball valve is opened, ball valves on the sides of the decentralized hydraulic station oil tanks needing oil supply are opened, oil is started to be supplied to the decentralized hydraulic station oil tanks, and the ball valves on the sides of the decentralized hydraulic station oil tanks are closed when oil supplied to the decentralized hydraulic station oil tank is up to the liquid level.

Description

technical field [0001] The invention relates to a system and a method for centralized oil replenishment for the oil tank of an online dispersed hydraulic station, especially suitable for industries that do not use a central hydraulic station but use decentralized hydraulic stations, and the oil grades used by the distributed hydraulic stations are the same production line. Background technique [0002] Distributed hydraulic stations are generally used in industrial production line hydraulic stations, and leakage is a common problem in hydraulic systems. Therefore, when the hydraulic system leaks, it is necessary to replenish the oil tank of the online distributed hydraulic station. [0003] The oil tank of the existing online decentralized hydraulic station often uses a refueling trolley to replenish oil. If a sudden leakage occurs in the hydraulic system, in addition to repairing the leak, sometimes the oil tank of the online dispersed hydraulic station must be replenished...
