Abstract
The utility model discloses a novel double-pump type pump station, comprising a base support, a variable pump component, an ejector valve and a constant pump component, wherein the constant pump component and the variable pump component can be converged in parallel in the ejector valve; and a valve block with an electromagnetic relief valve is arranged on the outlet of the constant pump component. In the utility model, the constant pump component is connected with the prior single variable pump component in parallel, thereby satisfying the requirement for high volume and solving the problem that the prior single pump type pump station has insufficient volume because the electromagnetic relief valve can be closed and opened flexibly to increase the volume; and the utility model has simple structure.
Description
Technical field
The utility model relates to a kind of pumping plant, is specifically related to a kind of pumping plant that adopts the double pump composite structure.
Background technique
Existing pumping plant adopts the configuration structure of single variable displacement pump mostly, it comprises base support 3, variable displacement pump assembly 1, variable displacement pump assembly 1 comprises variable displacement pump motor 11, variable displacement pump joiner 12 and variable displacement pump 13, variable displacement pump assembly 1 is installed on the base support 3, as shown in Figure 1, but progress along with society, existing single pump type pumping plant can not meet the demands, limited by component, unit list pump can not satisfy existing working condition requirement, mainly be that required big discharge capacity constant pressure variable displacement pump market resource is rare, there are problems such as discharge capacity deficiency in existing unit list pump.
Summary of the invention
The purpose of this utility model is at the problems referred to above deficiency, and a kind of novel double pump formula pumping plant that can increase discharge capacity flexibly is provided.
In order to achieve the above object, the utility model is by the following technical solutions:
Novel double pump formula pumping plant comprises base support, variable displacement pump assembly and ejector valve, also comprise one can with the variable displacement pump assembly in ejector valve and the metering pump assembly of combined stream, and the outlet of this metering pump assembly is provided with the valve piece of a charged magnetic relief valve.
Above-mentioned metering pump assembly is installed in one and is set up in scaffold on the variable displacement pump assembly, and this scaffold is fixedly mounted on the base support.
The utility model is simple in structure, and it is one group of metering pump group in parallel on the basis of original single variable displacement pump group, and the closed discharge capacity that increases flexibly by electromagnetic relief valve satisfies big discharge capacity requirement, solves the problem of existing single pump type pumping plant discharge capacity deficiency.
Description of drawings
Fig. 1 is existing single pump type pumping plant structural representation;
Fig. 2 is the structural representation of the utility model double pump formula pumping plant;
Fig. 3 is STRUCTURE DECOMPOSITION figure of the present utility model;
Fig. 4 is the STRUCTURE DECOMPOSITION figure of variable displacement pump described in the utility model;
Fig. 5 is the STRUCTURE DECOMPOSITION figure of metering pump described in the utility model.
Below in conjunction with the drawings and specific embodiments the utility model is further described:
Embodiment
Shown in Fig. 2,3,4 and 5, double pump formula pumping plant described in the utility model comprises base support 3, variable displacement pump assembly 1, metering pump assembly 2, scaffold 4, ejector valve and oil-way system.Described variable displacement pump assembly 1 comprises variable displacement pump motor 11, variable displacement pump joiner 12 and variable displacement pump 13, and variable displacement pump assembly 1 is installed on the base support 3.Described metering pump assembly 2 comprises the valve piece 24 of metering pump motor 21, metering pump joiner 22, metering pump 23 and charged magnetic relief valve, and described valve piece 24 is located at the outlet port of metering pump 23.Above-mentioned scaffold 4 is set up on the variable displacement pump assembly 1 and is fixedly mounted on the base support 3, and metering pump assembly 2 is installed on this scaffold 4.Further, outlet parallel connection in ejector valve of 2 outlets of metering pump assembly and variable displacement pump assembly 1 can realize metering pump and variable displacement pump and combined stream work.
Double-pump type pumping plant of the present utility model has the following advantages:
1) structure uniqueness: the constant displacement pump combination places on the variable pump combination;
2) being convenient to dismounting safeguards: the constant displacement pump combination is relatively independent with the variable pump combination, passes through screw attachment;
3) double pump outlet interflow: the constant displacement pump outlet connects a valve piece, and an electromagnetic relief valve is housed on the valve piece:
When 1. needing to collaborate, the outside control mouth of electromagnetic relief valve is closed, constant displacement pump and variable delivery side of pump interflow to System's fuel feeding;
2. in the time of need not collaborating, the outside control mouth of electromagnetic relief valve is opened, the constant displacement pump off-load, and variable pump is separately to being The system fuel feeding.
The utility model is simple in structure, and it is one group of metering pump group in parallel on the basis of original single variable displacement pump group, and the closed discharge capacity that increases flexibly by electromagnetic relief valve satisfies big discharge capacity requirement, solves the problem of existing single pump type pumping plant discharge capacity deficiency.
