When any end of the water cylinder body absorbs water, the water inlet at the water absorbing end is opened and the water outlet is closed, and when any end of the water cylinder body discharges water, the water inlet at the water discharging end is closed and the water outlet is opened.
For example, as shown in fig. 5, the inlet 3 may be connected to a water source 35 and the outlet 5 may be connected to a water storage tower 37 of a building. Taking the water cylinder as an example, when the water cylinder piston 1 slides leftwards, the water in the water cylinder body is discharged from the left water outlet 5 and enters the water storage tower 37, meanwhile, the water in the water source 35 enters the water cylinder body from the right water inlet 3, when the water cylinder piston 1 slides rightwards, the water in the water cylinder body is discharged from the right water outlet 5 and enters the water storage tower 37, and meanwhile, the water in the water source 35 enters the water cylinder body from the left water inlet 3.
The oil cylinder comprises an oil cylinder body and an oil cylinder piston 7. The cylinder piston 7 is slidably disposed in the cylinder body.

The piston rod 11 is provided with a receiving hole for the sensor 25 to extend into, and the magnet 23 is arranged on the cylinder piston 7.
With this arrangement, the sensor 25 can perform full-stroke position detection on the cylinder piston 7 by detecting the position information of the magnet 23 on the cylinder piston 7 to obtain the full-stroke position information of the cylinder piston 7, so that the operating state of the cylinder piston 7 can be controlled based on the position information of the cylinder piston. For example, when the oil cylinder piston 7 is about to run to the stroke end, the oil cylinder piston 7 can be decelerated by controlling an oil way valve body and the like, so that the problem of cylinder collision caused by collision between the oil cylinder piston 7 and an oil cylinder body is avoided, and the service life of the pumping device is prolonged.
