Piston advantage


The plunger piston is reciprocated by causing changes in the volume of the seal is achieved with the suction diesel pump manufacturers oil pressure, as compared with gear pumps and vane pump which has many advantages in the cylinder.
First, the parts constituting the sealed volume of the cylindrical piston and cylinder bore, easy to process, can be obtained with high accuracy, good sealing performance, high-pressure work is still high volumetric efficiency;
Second, simply by changing the working stroke of the plunger can change the flow, easy to implement variable;
Third, the piston in the main parts are under pressure stress, the material strength properties can be fully utilized.
Due to the high pressure submersible fuel pump
, compact structure, high efficiency, easy flow regulation, so the need for high pressure, high flow, high-power systems need to adjust the flow rate of the occasion and, as the goal planer, broaching machine, hydraulic machines, construction machinery, mining metallurgical machinery, widely used on the ship. Piston arrangement and the direction of movement of the plunger can be divided into radial and axial piston pump piston into two categories, according to the assignment device type can be divided with a gap-type seal with flow deputy piston and valve piston pump with flow control devices into two categories, according to whether the variable displacement piston pumps are divided into quantitative and variable piston pump.

Piston principle pump


Piston pump has been around for decades, its popularity depends on two main reasons:
1, they do not require external energy - the force of water to provide them with the required energy.
2, their equipment is extremely simple, with only two moving parts.
The basic principle is simple manual gas pump. Momentum This pump uses a relatively large movement of water to the relatively small volume of water pumped upward.
To use the plunger, there must be located above the water portable fuel transfer pump. For example, to have a pond on the hillside, so that you can install the water pump in the pond below. With a lead pipe water from the pond pump. Pumps have a valve that lets water flow through the pipes and acceleration.

Piston About folded edit this section


Hydraulic piston pump or solids pumps, hydraulic power pack to drive the hydraulic cylinders, hydraulic cylinders advance the delivery cylinder, the delivery of materials to pipe the output of the cylinder.
KOS hydraulic piston pump
KOS hydraulic piston pump
Generally divided into single and double piston plunger, typical representatives of the four kinds of German Putzmeister solids pumps, which are: EKO single piston portable fuel transfer pump, KOS, KOV, HSP three kinds of double-piston pump.
The pump belongs to positive displacement submersible fuel pump, especially for high solid content, long distance pipeline viscous material, the advantage is to run very stable and reliable, but noisy, delivery pressures up 130Bar, displacement of up to 0.5 to 500 cubic meters / hour. Widely used in sewage treatment, solid waste treatment, mining and metallurgy, dredging, dredging, petrochemical, power plants, cement industry and other fields.

Hydraulic piston pump


Hydraulic piston pump or solids pumps, hydraulic power pack to drive the hydraulic cylinders, hydraulic cylinders advance the delivery cylinder, the delivery of materials to pipe the output of the cylinder. Generally divided into single and double piston plunger, typical representatives of the four kinds of German Putzmeister solids hand gasoline pump, which are: EKO single piston pump, KOS, KOV, HSP three kinds of double-piston pump. The pump belongs to positive displacement petrol dispenser pump, especially for high solid content, long distance pipeline viscous material, the advantage is to run very stable and reliable, but noisy, delivery pressures up 130Bar, displacement of up to 0.5 to 500 cubic meters / hour. Widely used in sewage treatment, solid waste treatment, mining and metallurgy, dredging, dredging, petrochemical, power plants, cement industry and other fields.
