Overview

German first-hand source ALLWEILER plunger pump SVG 331: ALLWEILER screw pump, etc. *ALLWEILER pumps from Germany include centrifugal pumps, axial pumps, and screw pumps. Its ALLHEAT series of heat medium pumps are safe and professional heat medium transfer pumps. They have a wide range of applications in various fields such as polyester fibers, textile printing and dyeing, electronic lamination, plastics, leather, etc. They can be used to transport hot kerosene up to 350 degrees Celsius. Their characteristic is that they truly solve the problem of high-temperature heat medium transportation from a structural perspective and have the best cost-effectiveness

Product Details

German first-hand source ALLWEILER plunger pump SVG 331It is an important device in hydraulic systems. It relies on the reciprocating motion of the plunger in the cylinder body to change the volume of the sealed working chamber to achieve oil suction and pressure. Piston pumps have the advantages of high rated pressure, compact structure, high efficiency, and convenient flow regulation.

ALLWEILERWorking principle of plunger pump

German first-hand source ALLWEILER plunger pump SVG 331The total stroke L of the reciprocating motion of the plunger remains constant and is determined by the lift of the cam. The fuel supply amount per cycle of the plunger depends on the fuel supply stroke, which is variable and not controlled by the camshaft. The start time of fuel supply does not change with the variation of fuel supply stroke. Rotating the plunger can change the end time of fuel supply, thereby altering the fuel supply amount. When the plunger pump is working, the cam on the camshaft of the fuel injection pump and the plunger spring force the plunger to reciprocate up and down, thereby completing the pumping task. The pumping process can be divided into the following two stages.

ALLWEILEROil inlet process

When the convex part of the cam rotates, under the action of the spring force, the plunger moves downward, and the upper space of the plunger (called the pump oil chamber) generates a vacuum degree. When the upper end face of the plunger opens the oil inlet hole on the plunger sleeve, diesel filled in the oil passage of the upper body of the oil pump enters the pump oil chamber through the oil hole, and the plunger moves to the bottom dead center, and the oil inlet is completed

ALLWEILERReturn oil process

The plunger supplies oil upwards. When the inclined groove (stop supply edge) on the plunger is connected to the return hole on the sleeve, the low-pressure oil circuit in the pump chamber communicates with the middle hole, radial hole, and inclined groove of the plunger head. The oil pressure suddenly drops, and the oil outlet valve quickly closes under the action of the spring force, stopping the oil supply. Afterwards, the plunger will continue to move upwards. When the protruding part of the cam rotates past, under the action of the spring, the plunger will move downwards again. At this point, the next cycle begins. A plunger pump is introduced based on the principle of a plunger. There are two one-way valves on a plunger pump, and the directions are opposite. When the plunger moves in one direction, negative pressure appears in the cylinder. At this time, one one-way valve opens and the liquid is sucked into the cylinder. When the plunger moves in the other direction, the liquid is compressed and the other one-way valve is opened, and the liquid sucked into the cylinder is discharged. This working mode forms continuous fuel supply after continuous movement.
