Problems solved by technology

However, this structure also has the problem that the power end of the plunger is not stressed during the suction stroke (in theory), and the power end is stressed during the plunger discharge stroke, and the force is uneven.
The most important thing is that this structure is related to the area difference between the pump discharge flow and the stepped plunger. When the discharge flow required by the pump is relatively large, this structure is difficult to realize.
Because: (1) The diameter of the small head of the stepped plunger cannot be too small, the strength of the plunger is not enough if the diameter is too small, and the processing difficulty is also very difficult (slender rod) and the machining accuracy is difficult to guarantee; (2) The large head of the stepped plunger The diameter should not be too large. If the diameter of the big head is simply increased, then for multi-cylinder pumps, the distance between the cylinders of the pump will be very large, and the distance between the cylinders of the matching power end will also be large. Generally speaking, the power end with large cylinder distance will carry The capacity is also large, and the power end capacity will be rich, resulting in the waste of large horse-drawn carts
Since the large end of the stepped plunger cannot be too large and the small end cannot be too small, the scope of application of this patented technology is limited

Embodiment 1

[0014] The double-acting reciprocating booster pump of the present invention is composed of a double-step plunger 1 and a pump body 2, and the pump body is integral, such as figure 1 As shown, the pump body 2 is provided with a left volume chamber 9 and a right volume chamber 10, a suction valve assembly I4 and a discharge valve assembly I3 are installed in the left volume chamber 9, and a suction valve assembly II6 is installed in the right volume chamber 10 and discharge valve assembly II5; a double-step plunger 1 and its sealing assembly are installed between the left volume chamber 9 and the right volume chamber 10, and the double-step plunger 1 and its sealing assembly separate the left volume chamber 9 and the right volume chamber 10 . And at the two ends of the main plunger of the double-step plunger 1, there is an auxiliary plunger I7 and an auxiliary plunger II8 with the same diameter and their sealing components. The diameters of the auxiliary plunger I7 and the auxi...

Embodiment 2

[0016] In the double-acting reciprocating booster pump of the present invention, the pump body is split, such as figure 2 Shown, others are with embodiment 1. The double-step plunger seal assembly of the present invention may also adopt a stepped piston seal assembly structure.

[0017] The specific working process is as follows:

[0018] When the double-stepped plunger 1 moves to the right, the suction valve 4 of the volume chamber 9 at the left end is opened, the discharge valve 3 is closed, and the volume chamber 9 at the left end completes the suction process. At this time, the suction valve 6 of the volume chamber 10 at the right end is closed, and the discharge valve 5 is opened. , the right end volume chamber 10 completes the discharge process. A rated flow is discharged during this process. At the same time, the plunger is subjected to a leftward force F1=π(D 2 -d 2 )(P2-P1) / 4;

[0019] When the double-step plunger 1 moves to the left, the discharge valve 5 of t...

Abstract

The invention provides a double-acting reciprocating booster pump and belongs to the technical field of reciprocating pumps. The double-acting reciprocating booster pump is composed of a double-step plunger piston and a pump body. A left volume cavity and a right volume cavity are arranged on the pump body, a suction valve assembly I and a discharge valve assembly I are installed in the left volume cavity, and a suction valve assembly II and a discharge valve assembly II are installed in the right volume cavity. The double-step plunger piston and a sealing assembly of the double-step plunger piston are installed between the left volume cavity and the right volume cavity and separate the left volume cavity and the right volume cavity. The double-acting reciprocating booster pump is novel in structural design, has two flow discharging strokes in one reciprocating motion stroke of the double-step plunger piston and increases discharge flows in a multiplied mode. In addition, stress on two sides of the double-step plunger piston in the suction and discharge strokes are the same. The double-acting reciprocating booster pump always provides same acting force for a power end and solves the problem that the stress of a conventional booster pump in the suction and discharge strokes are uneven.

Description

technical field [0001] The invention belongs to the technical field of reciprocating pumps, and in particular relates to a double-acting reciprocating booster pump. Background technique [0002] The reciprocating booster pump is a traditional machine that pressurizes the conveyed liquid medium by driving the plunger or piston to reciprocate. The conveyed medium has a certain inlet pressure. [0003] Usually, the reciprocating booster pump uses the area difference of the large and small plunger to balance the reaction force of a part of the inlet pressure to the power end. However, there is always a gap between the inlet pressure and discharge pressure data provided when designing the difference between the size and head of the booster pump plunger and the actual work, which always affects the normal work of the power end. The invention patent with Chinese patent number 200910059897.4 discloses an inlet pressure balanced booster water injection pump. Its main features are: ...
