Embodiment Construction

[0020] figure 1 As shown, the specific implementation is as follows:

[0021] An independent circulation filtering temperature-controlled water-cooled hydraulic system, including a motor 3, a hydraulic pump 4 and an oil suction filter 13, the hydraulic pump 4 is connected to the oil tank through the oil suction filter 13, the motor 3 drives the hydraulic pump 4 to work, and the oil output of the hydraulic pump 4 One of the ends of the hydraulic pump 4 passes through the sequence valve 5 and the oil return filter 2 into the oil tank in turn, and the two ends of the oil return filter 2 are connected in parallel with a check valve 1 that is normally unconnected, and one of the oil outlet ends of the hydraulic pump 4 passes through the throttle valve in turn. 11 and thermal relief valve 12 lead into the oil tank so as to automatically detect the oil temperature and automatically adjust the oil inlet pressure of thermal relief valve 12 according to the oil temperature. The valve 9...

Abstract

The invention relates to an independent circulating filtration temperature-control water-cooling hydraulic system. A hydraulic pump is connected with an oil tank through an oil suction filter; one path of an oil outlet end of the hydraulic pump is fed into the oil tank through a sequence valve and an oil return filter; one-way valves which are not connected at a normal state are connected to two ends of the oil return filter in parallel; one path of the oil outlet end of the hydraulic pump is fed into the oil tank through a throttle valve and a temperature-sensitive overflow valve; one path of the oil outlet end of the hydraulic pump is fed into the oil return filter through a two-way solenoid valve, a back pressure valve and a water cooler; one path of the oil outlet end of the hydraulic pump is connected with a two-inlet one-outlet three-way solenoid valve; the hydraulic pump is connected with one inlet of the three-way solenoid valve; an oil outlet end of the throttle valve is connected with the other inlet of the three-way solenoid valve; and an outlet of the two-inlet one-outlet three-way solenoid valve is connected with a liquid control proportion water valve for controlling the water cooler. According to the independent circulating filtration temperature-control water-cooling hydraulic system provided by the invention, when a petroleum coke conveyor works at an extremely cold environment, the environment temperature is low, and hydraulic oil needs to be heat to appropriate temperature so as to ensure the system to work reliably.

Description

technical field [0001] The invention relates to the technical field of delayed coking in the petroleum refining industry, in particular to an independent circulation filtering temperature-controlled water-cooling hydraulic system. Background technique [0002] Delayed coking is a petroleum processing technology, using heavy oil as raw material, the coking reaction is carried out in the coke tower, and the coke produced is coked in the tower. Open the upper and lower covers of the coke tower, use the hydraulic decoking method to break the coke and discharge it from the lower tower mouth, close the upper and lower covers of the coke tower, and then enter the next production cycle. [0003] At present, the discharged coke and water flow into the coke pool for dehydration, and the coke in the pool is dumped and grabbed by the grab crane, and then enters the next process for processing or directly loads and transports. The coke pool is set in the open air. During the process of ...
