Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hydraulics, and particularly relates to a new type of self-locking pressure-maintaining oil station. Background Art
[0002] In the early stage, the hydraulic system controlled the oil cylinder of the circulating water butterfly valve by controlling the hydraulic check valve through an electromagnetic ball valve. The electromagnetic valve belongs to a two-position four-way electromagnetic valve. When the power is off, the butterfly valve is in the closed state, and when the power is on, the butterfly valve is in the open state. When the oil cylinder needs to act, the electromagnetic valve and the hydraulic check valve need to act simultaneously. Since the electromagnetic valve and the hydraulic control valve need to cooperate with each other to effectively control the butterfly valve, and the hydraulic control valve on the system is a cartridge valve, poor oil quality is likely to cause jamming. Once any of these devices fails, the entire control system will fail. In order to troubleshoot problems, a thorough overhaul is required, which results in high failure rates and a large amount of maintenance work. Content of the Utility Model
[0003] The purpose of the utility model is to provide a new type of self-locking pressure-maintaining oil station to solve the problems raised in the above background art.
[0004] To achieve the above purpose, the utility model provides the following technical solution: A new type of self-locking pressure-maintaining oil station, including an oil tank, and also including a motor, a hydraulic pump, a pressure sensor assembly, an accumulator, a throttle valve and a manual valve. The motor drives the hydraulic pump to pump oil. The hydraulic pump is connected to the pressure sensor assembly through a first plate-mounted valve. The accumulator is connected to the first plate-mounted valve. A second plate-mounted valve and a third plate-mounted valve are provided between the accumulator and the throttle valve. One end of the manual valve is connected to a fourth plate-mounted valve, and the other end of the manual valve is connected to a manual pump. A fifth plate-mounted valve is provided between the manual valve and the manual pump.
[0005] Preferably, there are two accumulators, and the volume of each accumulator is 40L.
[0006] Preferably, an air filter, an oil filter and a temperature sensor are also provided in the oil tank.
[0007] Preferably, an oil level gauge is provided in the oil tank.
[0008] Preferably, a pump suction oil filter element is provided at the inlet of the hydraulic pump.
[0009] Preferably, a pump outlet oil filter element is provided at the outlet of the hydraulic pump, and differential pressure transmitters are connected to both ends of the pump outlet oil filter element.
[0010] Preferably, the pump outlet oil filter element is connected to an overflow valve.
[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: The multiple plate-mounted valves provided by the present utility model can prevent the plug-in hydraulic valves from jamming; two 40L accumulators are used as auxiliary power sources. Only when the system pressure is lower than a certain value, the oil pump will automatically start, preventing the oil pump from starting frequently; and when the circulating water butterfly valve is fully open or fully closed, the solenoid valve is de-energized, and the pressure oil will not enter the oil cylinder, and the pressure oil in the oil cylinder is blocked by the hydraulic check valve, thereby preventing the movement of the oil cylinder; in order to avoid opening and closing the circulating water butterfly valve when the oil pump loses power, an additional manual pump is added, which can be manually operated to open the butterfly valve, increasing the reliability of the system.
