Problems solved by technology

In this way, not only the commutation is unstable and unreliable, but also the control circuit part of the reversing device is controlled by a circuit board. Since the circuit board is a non-standard part, and it is difficult to manufacture and process, it is very difficult to repair after damage, which increases subsequent use and maintenance. cost
At the same time, if the existing reversing device is continuously energized for a long time, it is easy to damage small devices and cannot meet the requirements of long-term energization, which also affects the use efficiency to a certain extent

Embodiment Construction

[0024] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] combine figure 1 As shown, the reciprocating plunger pump in this embodiment includes a housing 1 , a piston cylinder 2 , a piston 3 , a first plunger 41 and a second plunger 42 . Wherein, along the axial direction, the first plunger 41 and the second plunger 42 are respectively fixedly connected to two ends of the piston 3 , and the piston 3 drives the first plunger 41 and the second plunger 42 to move synchronously in the axial direction.

[0026] The housing 1 is a hollow structure, and the housing 1 is provided with a P port, a T1 port, a T2 port, a first liquid inlet hole 15, a first liquid outlet hole 16, a second liquid inlet hole 17 and a second liquid outlet hole 18. Wherein, the P port is connected with the oil inlet pipe, the T1 port and the T2 port are respectively connected with the oil outlet p...

Abstract

The invention belongs to the technical field of reciprocating plunger pumps. The invention discloses a reciprocating type plunger pump. The pump comprises a shell, a piston cylinder, a first plunger and a piston. The shell is provided with a port P connected with an oil inlet pipe, and a port T1 and a port T2 which are connected with an oil outlet pipe. The piston cylinder is located in the shell,the piston is located in the piston cylinder, the piston can do axial reciprocating motion under an effect of high-pressure oil, the piston cylinder can do axial reciprocating motion relative to theshell under the effect of the high-pressure oil, two sides of the piston are alternately connected with the high-pressure oil, and automatic reversing reciprocating motion of the hydraulic cylinder isachieved. The reciprocating plunger pump can carry out automatic reversing reciprocating movement under driving of hydraulic pressure, is simple and compact in structure, low in manufacturing cost and high in integration level, can omit use of a reversing valve, does not need electric control, avoids unstable factors of electric appliances, can work for a long time, and is long in service life.

Description

technical field [0001] The invention belongs to the technical field of reciprocating pumps, and in particular relates to a reciprocating plunger pump. Background technique [0002] With the large-scale application of large-scale mechanical equipment, the use of hydraulic drive technology in the field of fluid compression application technology is becoming more and more mature. Among them, in the field of reciprocating plunger pump technology for compressing fluid, the traditional reciprocating plunger pump uses a crank connecting rod mechanism to realize the reciprocating movement of the piston in the cylinder to compress the fluid. The output pulse of the type plunger pump is large and unstable, and it is easy to get stuck under severe working conditions. [0003] In addition, in the current hydraulic reciprocating plunger pump, the reversing valve that realizes the reciprocating movement of the piston mostly uses an electromagnetic reversing valve and a displacement senso...
