What are the general uses of T6 series vane pumps and check valves in hydraulic systems? Most people should have heard that the conditions for the T6 series vane pump to work normally are: it should have a sealed volume, the size of the sealed volume can be changed alternately, and there should be a flow distribution device.
The function of the flow distribution device is to ensure that the sealed volume communicates with the fuel tank during the oil suction process, and at the same time closes the oil supply passage; when the oil is pressed, it communicates with the oil supply pipeline and cuts off the fuel tank, so the T6 series vane pump and check valve in the hydraulic system What are the general benefits? Let me give you a detailed explanation of the usefulness of T6 series vane pumps and check valves in hydraulic systems as follows:
1. The one-way valves 4 and 5 in the T6 series vane pump are flow distribution devices, and the form of the flow distribution device varies with the structure of the pump. During the oil suction process, the fuel tank needs to communicate with the atmosphere.
2. Schematic diagram of T6 series vane pump: In order to read the schematic diagram of hydraulic transmission correctly and quickly, one must first have a good grasp of hydraulic knowledge, be familiar with the working principles, functions and characteristics of various hydraulic components; understand and master the hydraulic system. Some properties of the basic circuit and oil circuit; familiar with the various control methods of the hydraulic system and the symbols in the diagram.
3. Secondly, connect with reality in the work, read more and practice more, and understand the characteristics of the system through various typical hydraulic systems.
4. The main function of the one-way valve (check valve) is to prevent the flow of oil in one direction, and to realize free flow in the opposite direction. Stopping the flow must be leak-free, so these valves are always seated.
5. There are several types of sealing elements: steel ball: (1), cone valve core (2), valve seat (3) and cartridge valve (4). Only a small hydraulic pressure is required to open the valve against the spring force of the sealing element.
6. (1) One-way valve structure type, which can prevent the reverse of the drive shaft of the hydraulic pump when the load drops; (2) Reverse free flow of the throttle valve (one-way throttle valve); (3) Used as (4) used as an anti-cavitation valve for rotational inertia loads; (5) used as a bypass valve when the oil suction filter is blocked, (6) used as a bypass valve when the oil return filter is blocked Bypass valve, (7) bridge flow control valve (to ensure that one direction passes through the flow valve); (8) used for closed system oil replenishment circuit.
