Working Principle of Hekvek Hydraulic Pump
Hekvek hydraulic pump is the power component of the hydraulic system. The hydraulic pump consists of two hydraulic cylinders of different sizes, which are filled with water or oil. Water filling is called "hydraulic press" and oil filling is called "hydraulic press".
Each of the two Hekvek cylinders has a sliding piston. If a certain value of pressure is added to the small piston, according to Pascal's law, the small piston transfers this pressure through the pressure of the liquid to the big piston, and the top of the big piston goes up. Let the cross-sectional area of the small piston be S1 and the downward pressure on the small piston be F1. Therefore, the small piston pair can be transferred in all directions by the liquid with the same size. The pressure on the big piston must also be equal to P. If the cross-sectional area of the large piston is S2, the upward pressure cross-sectional area generated by the pressure P on the large piston is a multiple of the cross-sectional area of the small piston.
From the above formula, if a small force is added to the small piston, a large force will be obtained on the large piston. For this reason, hydraulic pump is used to press plywood, press oil, extract heavy objects, forge steel, etc. Driven by an engine or an electric motor, it sucks oil from a hydraulic tank to form a pressure oil drain and sends it to an actuator.
Hekvek hydraulic pump is divided into gear pump, plunger pump, vane pump and screw pump according to its structure.
The transmission shaft of hydraulic pump can not bear the radial and axial forces, so it is not allowed to install pulleys, gears and sprockets directly at the end of the shaft. Usually, the coupling is used to connect the drive shaft and the pump transmission shaft. If the coaxiality of pump and coupling exceeds the standard due to manufacturing reasons and there is deviation in assembling, the centrifugal force will increase with the increase of pump speed, and the centrifugal force will increase with the increase of deformation. Cause vicious circle, resulting in vibration and noise, thereby affecting the service life of the pump.
In addition, there are other factors such as loose coupling pin not tightened in time, rubber ring wear not replaced in time and so on.
