Description

Technical Field

[0001] The utility model belongs to the technical field of plunger pumps and relates to a vertical plunger pump with a non-deflecting piston. Background Art

[0002] A plunger pump is a power source for hydraulic systems. It relies on the reciprocating motion of a plunger within a cylinder, causing the volume of a sealed working chamber to change, thereby absorbing and compressing oil. Plunger pumps offer advantages such as compact structure, high efficiency, and easy flow control.

[0003] Plunger pumps are widely used in situations where high pressure, large flow and flow regulation are required. They are a typical positive displacement hydraulic machine driven by a prime mover. They convert the input mechanical energy into liquid pressure energy, which is then input into the system in the form of pressure and flow. They are the power source of the hydraulic system. Since they can transport liquids under high pressure, they are widely used in various industries in industrial production and daily life.

[0004] The existing plunger pump has a horizontal structure, which occupies a large area and has low space utilization. It is inconvenient to install and maintain, and workers need to bend over or even sit on the floor of the workshop to operate it. The inconvenient operation leads to long installation and maintenance time and low efficiency, which does not meet modern production standards. Utility Model Content

[0005] The purpose of this utility model is to overcome the above defects, solve the corresponding technical problems, and provide a vertical plunger pump with a non-deflective piston, which saves space, improves the production efficiency of the enterprise, and creates more profits for the enterprise.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: a vertical plunger pump with non-deflected piston, characterized in that when the oil cylinder and the cylinder barrel are fixed, the connecting flange used is of the upper groove and lower boss type, the upper groove surface of the flange is in contact with the oil cylinder and fixed, and the lower boss part is embedded in the cylinder barrel, which not only connects and fixes the two but also ensures that the coaxiality of the two (oil cylinder and cylinder barrel) is in a straight line, thereby ensuring that the piston is unbiased; secondly, a reversing limit rod is added next to the oil cylinder, and the pistons of the two sets of devices are operated asynchronously by relying on electrical signals, thereby realizing the cyclic operation of the plunger pump.

[0007] Furthermore, the connection direction of each component is changed, and the connection between the oil cylinder and the cylinder barrel is changed from horizontal to longitudinal, which is more in line with the mechanical structure and lays the foundation for the piston to be non-deflected. Secondly, the connecting flange with upper groove and lower boss creates conditions for the piston to be non-deflected. The oil cylinder is vertically located in the concave groove of the connecting flange, which fits perfectly to ensure the coaxiality of the oil cylinder and the flange. The cylinder barrel is connected to the bottom of the flange, and the lower boss of the flange is embedded in the groove of the cylinder barrel and cooperates with the groove of the cylinder barrel. A sealing strip is embedded in the inner ring of the groove to ensure the sealing performance of the cylinder barrel. The perfect cooperation between the connecting flange and the cylinder barrel fixes the oil cylinder, connecting flange and cylinder barrel together, and the axes of the three coincide on a straight line, thereby ensuring that the piston is non-deflected.

[0008] Furthermore, a reversing limit rod is added next to the oil cylinder, and the electrical signal controls the two sets of main pump bodies so that the pistons of the two sets of main pump bodies run in opposite steps. One piston is at the top of the cylinder and the other piston is at the bottom of the cylinder, rising and falling one by one, ensuring that the material is continuously sucked in and transported out.

[0009] The utility model provides a vertical plunger pump with a non-deflective piston, which has the advantages of stable structure, convenient assembly, and space saving, thereby reducing maintenance difficulty and improving enterprise production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation plan

[0017] The following describes the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings of an embodiment of a vertical plunger pump with a non-deflective piston. The described embodiments are only a portion of the preferred embodiments of the present invention, not all of the embodiments. All other non-inventive embodiments made by those skilled in the art based on the embodiments of the present invention fall within the scope of protection of the present invention. Example

[0018] A vertical plunger pump with a non-biased piston membrane, the pump body is composed of two sets of identical parts connected in series, specifically including an oil cylinder, a cylinder barrel, a connecting flange, a superimposed one-way valve, a bottom support seat, an inlet and outlet flange, etc. The oil cylinder 6, the connecting flange 4, the cylinder barrel 2 and the bottom support seat 1 are installed vertically to form the main pump body of the vertical plunger pump, and the two sets of main pump bodies each form a system without interfering with each other; the bottom support seat 1 and the superimposed one-way valve 10 are connected horizontally by flanges, and the main pump body of each vertical plunger pump corresponds to a superimposed one-way valve 10, which is connected in series on the pipeline of the inlet flange 9, and the pipeline of the outlet flange 11 is sandwiched between the two superimposed one-way valves and connected to the superimposed one-way valve 10 to transport materials outward; the connection method of the main pump body is longitudinal connection, the oil cylinder 6 is vertically located in the upper groove 41 of the connecting flange 4, and the lower boss 42 of the connecting flange 4 is embedded in the cylinder barrel groove 21, and the connection between the cylinder barrel and the bottom support seat 1 is also made of flanges.

[0019] A vertical plunger pump with a non-deflective piston. The power source 8 is started, and the power is delivered to the oil cylinder 6 through the oil pipe. The piston rod 5 moves up slowly, and the material is sucked in from the feed port flange 9. After passing through the superimposed one-way valve 11, the valve in the feed direction is opened, and the piston rod 5 drives the piston 3 to move up slowly. The material passes through the bottom support seat 1 and is continuously sucked in as the piston slowly moves up. At the same time, the piston rod of another set of main pump body drives the piston to slowly descend from the top of the cylinder 2. The slowly descending piston exerts pressure on the material, forcing the pressure of the material to increase during the descent. The material reaches the bottom support seat, and the superimposed one-way valve 10 is discharged. The valve in the material direction opens, and finally the material is discharged from the discharge port flange 11 under pressure. During this process, when the piston rod drops to a certain level and cannot drop any further, it touches the reversing limit rod 7, and the reversing limit rod transmits an electrical signal to the piston rod at the top of the cylinder, and the piston rod drives the piston to drop, while the piston that has just dropped is driven by the piston rod to rise, and the action just now is repeated continuously. The pistons are always in different paces, one piston 3 is at the top of the cylinder, and the other piston is at the bottom of the cylinder, one drops and the other rises at the same time, and this reciprocating operation ensures that the suction and output of the vertical plunger pump are uninterrupted.
