Embodiment Construction
[0033] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0034] According to an embodiment of the present invention, such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5a , Figure 5b , Figure 5c with Figure 5d As shown, a hydraulic cylinder piston with a safety device is provided. The hydraulic cylinder piston with the safety device is built in the hydraulic cylinder, the hydraulic cylinder is equipped with a signal sensor, and the energy recovery device system senses and controls the operating state of the switcher through the external signal sensor of the hydraulic cylinder, thereby Change the flow passage of high-pressure concentrated brine into the hydraulic cylinder.
[0035] Such as figure 1 ,...

The invention discloses a water hydraulic cylinder piston with a safety device. The water hydraulic cylinder piston comprises a horizontally-arranged water hydraulic cylinder piston pipe body, two blocking plates bilaterally and symmetrically arranged inside the water hydraulic cylinder piston pipe body, a plurality of positioning pipes located inside the water hydraulic cylinder piston pipe body, evenly distributed on the periphery and horizontally arranged between the blocking plates, vertically-arranged valves plates located inside the water hydraulic cylinder piston pipe body, close to the seal blocking plate and penetrating the corresponding ends of the positioning pipes, and a plurality of sensing blocks located at the positions on the outer side of the middle of the water hydraulic cylinder piston pipe body, wherein one blocking plate is a seal blocking plate, the other blocking plate is a non-seal blocking plate. The water hydraulic cylinder piston with the safety device can overcome the defects of low reliability, poor safety and the like in the prior art and accordingly has the advantages of high reliability and good safety.
Description
technical field [0001] The invention relates to the technical field of pistons, in particular to a hydraulic cylinder piston with a safety device. Background technique [0002] At present, the conventional hydraulic cylinder piston can only reduce the mixing of high-pressure concentrated brine and low-pressure raw seawater in the energy recovery device, and control the operation of the switch through its operating position. [0003] At present, reverse osmosis seawater desalination is one of the mainstream technologies for seawater desalination. In order to overcome the osmotic pressure of water, the reverse osmosis seawater desalination process needs to consume a lot of electric energy to increase the water inlet pressure of the reverse osmosis membrane, while the residual pressure of concentrated brine discharged from the reverse osmosis membrane As high as 5.5-6.5MPa, calculated according to the recovery rate of 42%, the discharged concentrated brine also contains about 5...
