Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a fluid transfer pump system having a valve chamber,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cylinder pump system for transferring fluids, and more particularly, to a fluid transfer cylinder pump system having a separate valve chamber communicating with a cylinder to facilitate valve management, foreign matter collection, and installation of additional equipment.

The pump is a device that transports liquid or gas fluid through piping by pressure action, or pushes fluid in a low-pressure container through piping into a high-pressure vessel. It is equipped with facilities for preventing pollution such as sewage treatment facilities, Oil wells such as natural gas, fluid transportation facilities for the chemical industry, and pumping water facilities. Especially, in the environmental pollution prevention facilities such as sewage treatment facilities, waste water treatment facilities, livestock manure treatment facilities, livestock manure recycling facilities, and waste disposal facilities, various sludges are obtained at various stages of the treatment process. Such sludge and various industries Pumps used for the transport of medicines or special fluids such as pulp, viscose and petroleum should meet the requirements reinforced in terms of performance and management.

Generally, in an actual fluid transfer environment in which such pumps are used, sand, rocks, metal pieces or the like may be mixed with the fluid, or scales from the fluid transfer pipe, pieces of the inner surface of the old pipe, various solid components, This foreign matter flows into the pump along with the flow of the fluid, thereby causing malfunction or breakage of the valve, cylinder, piston or the like which is an internal constituent of the pump, thereby causing the performance of the pump system to be lowered or the operation to be stopped .

In addition, these pumps are installed in places where they are hardly received technical assistance after they are installed at the site of use, and after they have been installed and started to operate, they stop their operation and change their internal structure, It is necessary to have a structure that can prevent the problem due to foreign matter inflow and also it is necessary to have a structure that is robust and simple in the case of new introduction considering the various viscosity of the transfer fluid, the variable situation of the pump installation site, Should be manufactured and installed.

However, in the conventional pump system, it is difficult to repair or replace the valve by providing the valve on the lower portion of the cylinder or on the side surface thereof. The foreign substances introduced into the pump system move freely into the valve, the piston, Which causes problems or makes them worse. Even when the viscosity of the transported fluid changes or the characteristics of the driving force (for example, the rotation fluctuation period, the fluctuation angle range, etc.) change or the aging of the pump system needs to be changed due to the aging of the pump system, The conventional pump system can not change the transfer flow rate. Therefore, it is necessary to install the pump in a structure that is always operated at the maximum transfer flow rate and to separate the piping to discharge or return by bypassing the unnecessary flow rate It also adopts a method of adding a structure.

In order to solve such a problem, a filtration means such as a screen filter may be provided at the end of the inlet pipe of the pump system to filter out a large floating substance, sand, stone, or metal fragments introduced into the inlet pipe, Not only the performance itself is limited but also there is no countermeasure against scale fragments of the inflow pipe that is mixed in the flow in the inflow pipe, the scrap piece of the old pipe, and various solid components.

Further, as a conventional technique for adjusting a driving force inputted from a driving source, a technique relating to a variable fluid transfer pump system (hereinafter referred to as 'prior art') such as that disclosed in Japanese Patent Application Laid-Open Nos. 10-1382049 and 10-0337565, However, in the above-mentioned prior art, variable driving of the pump by the hydraulic pressure regulator 1 is too complicated in its overall structure, which leads to a decrease in reliability of the system and an increase in the maintenance cost, There is a problem in that it is difficult to appropriately cope with the case where the characteristics of the driving force (for example, the rotation fluctuation period, the fluctuation angle range, etc.) change or the operation structure of the pump needs to be changed due to aging of the pump system. In addition, when a plurality of the pumps 10 are provided, the disadvantages are further increased.

Even in the management such as the inspection and replacement of the installed sensors or the additional structure, And provides significantly improved usability.

In one embodiment of the present invention, a variable power transmission structure of patent application No. 2017-0061899 (May 17, 2018), filed by the applicant, for efficient operation of the pump system may be provided, The driving force transmitting portion 20 for transmitting the transmitted driving force to the piston 12 transmits the driving force of the external driving source to the piston 12 in a pivoting manner so that the piston 12 is driven to reciprocate linearly in the cylinder 11 do. The pivot adjusting means 50 includes a pivot adjusting means 50 for changing the pivot position of the driving force transmitting portion 20 to a target position The driving force transmitted to the piston 12, the driving distance, and the like are changed. By using such a relatively simple structure, it is advantageous to improve the reliability of the system, the pump efficiency, and the durability.

The driving force transmitting portion 20 includes a first link 21 and a second link 22, a pivot 22, a pivot 22, Link 23 so as to have a deformed structure of the slider-crank mechanism. The first link 21 is rotatably connected to the piston 12 of the pump body 10 by being hinged at one end thereof and the second link 22 is connected to the piston 12 of the pump body 10 by a predetermined driving force And the pivot link 23 is hinged to the other end of the first link 21 and the end of the second link 22 so as to be pivotally connected to each other, 22, the first link 21 is provided with a slot portion (not shown) extending in the longitudinal direction thereof so as to allow the pivot shaft 53, 25 are provided so that the pivotal position of the pivotal link 23 is adjusted within the slot 25 by the pivotal adjustment means 50. At this time, it is preferable to consider the material and the dimensions so that the structural strength of the portion where the slot 25 is formed in the pivot link 23 is sufficiently secured.

The pivot adjusting means 50 is configured to include a pivot body 52 and a pivot shaft 53 and a pivot guide member 54. The pivot guide member 54 is provided on the support member 51 and may be formed in the form of a through bar as shown in FIG. And the pivot guide member 54 functions to stabilize the posture of the pivot body 52 while guiding the movement of the pivot body 52. [ Here, the support member 51 may be separately formed and coupled to the base member B, but may be formed as a part of the base member B for simplification of the entire structure. The pivot body 52 is movably provided along the pivot guide member 54 and the pivot shaft 53 is provided on one side of the pivot body 52. The pivot shaft 53 is connected to the pivot link 23, So that the pivotal support of the driving force transmitting portion 20 with respect to the pivot link 23 is performed. The positioning of the pivot shaft 53 within the slot portion 25 is realized by adjusting the position of the pivot body 52.

The positional movement of the pivot shaft 53 by the pivot adjusting means 50 may be manually operated. However, in order to effectively utilize the pump system, the automatic adjusting method by the controller is preferable. In the automatic adjusting method, (56), a pivot control unit (57), and monitoring means (not shown), and calculates the target position of the pivot shaft (53) by referring to the sensing signal of the monitoring means The driving of the pivot driving means 56 is controlled so as to move to the target position.

The pivot drive means 56 may be installed inside the pivot body 52 to directly drive the pivot body 52. The pivot drive means 56 may be installed on the pivot guide member 54 or the support member 51 side, A method of driving the pivot body 52 through the transmission mechanism is preferable from the viewpoint of ensuring driving force and maintenance. For example, a structure in which the pivot guide member 54 is formed of a screw-type drive rotation shaft and a nut-shaped through hole is formed in the pivot body 52 to drive the pivot body 52 by a ball screw system At this time, as the pivot drive means 56, the motor is directly coupled to the screw-type rotation shaft and driven, or is transmitted to the screw-type rotation shaft through a gear box, a chain, or the like. At this time, since the driving rotary shaft of the pivot driving means 56 may also serve as the pivotal guiding member 54, it can be seen that the pivot driving means 56 and the pivotal guiding member 54 are integrally formed.

The pivot control unit 57 calculates the target pivot position using the sensing signal of the monitoring means (not shown), and reflects the result to transmit a proper driving command signal to the pivot driving means 56. [ The pivot control unit 57 is preferably disposed in the vicinity of the pivot driving means 56, but may be disposed in another configuration or space of the pumping system as required.

The monitoring means (not shown) detects at least one or more of the viscosity of the transfer fluid, the flow rate of the pump system, the rotation frequency of the external driving force, the rotation angle, and the strain of the driving force transmission unit 20, And the pivot control unit 57 calculates the target position of the pivot shaft 53 by referring to the sensing signal of the received monitoring means (not shown). The pump system of the present invention provides a driving force transmission in a pivoting manner The driving force, the driving force, and the supporting stress can be easily predicted by adopting the method of simply varying the pivot position only in accordance with the magnitude of the driving force required according to the viscosity of the transported fluid, Depending on the stroke distance of the piston taking into account the rotation frequency, rotation angle, required transfer flow, etc., the magnitude of the stress sensed in each configuration and the degree of aging of the pump system Depending on the consideration of the driving transfer force, it has an advantage that can easily calculate the pivot axis target position.

However, if a pump system is actually manufactured and installed, it is possible to increase the rigidity of the link due to the eccentricity of mass, the arrangement structure, the alignment error, and the machining tolerance of each structure. The structure often deviates from the plane of motion, which is further exacerbated as the operating time of the pump system increases, causing problems in terms of operational reliability, durability, and noise performance of the overall system. In order to solve such a problem, the pump system of the present invention may further include a link guide member 70 such that each link of the driving force transmitting portion 20 performs link motion stably in the plane of motion.
