Description
Technical field
The utility model relates to a kind of hydraulic means, particularly a kind of compact pumping plant.
Background technology
Hydraulic power unit generally adopts the hydraulic oil meeting hydraulic system requirement to make ature of coal, by motive power through pumping out the ature of coal of meet the requirements flow and pressure for hydraulic system.Current existing hydraulic pump mostly is by the drive source of motor as oil pump, the mechanism of hydraulic power unit each valve and and the assembly supporting with it be contained on integrated oil path plate, or be layering, electric machine external, causes that hydraulic power unit is bulky, complex structure, not easy care.Especially in use, run into unexpected power-off or power failure, hydraulic power unit is often caused to quit work, very likely cause the generation of security incident, therefore great unsafe factor is brought to hydraulic test, cause hydraulic test commercially to lack competitiveness therefrom, bring adverse influence also to the direction of hydraulic test industry development simultaneously.
Utility model content
The purpose of this utility model is the shortcoming overcoming prior art, provides a kind of compact pumping plant of safe and reliable, compact conformation.
The purpose of this utility model is achieved through the following technical solutions: a kind of compact pumping plant, it is characterized in that: it comprises fuel tank, pump assembly closes, hydraulic manifold block and reversal valve group, pump assembly closes and is arranged in fuel tank, described pump assembly closes and is made up of motor and oil pump, the output shaft of motor is connected with the rotating shaft of oil pump, hydraulic manifold block is arranged on top of oil-tank, described hydraulic manifold block is by overflow valve, unloader, speed changing-over valve and flow speed control valve composition, a road manual actuation oil circuit and a road hydraulic circuit is connected in hydraulic manifold block, the manual actuation oil circuit of hydraulic manifold block is connected to manual pump, the hydraulic circuit of hydraulic manifold block is connected with oil pump and reversal valve group respectively.
Described fuel tank is provided with liquid level and takes into account thermometer.
Described hydraulic manifold block is provided with Pressure gauge.
Described manual pump is provided with handle.
The utility model has the following advantages:
1. the utility model is by electric machine built-in in fuel tank, adopts modular multiple directional control valve, reduces the application of integration module, and adopt plug-in overflow valve and flow speed control valve, these spaces of all having saved system make pumping plant mechanism compacter.
2. adopt motor and manual two kinds of type of drive, ensure that under power-off or the inoperable situation of motor, can adopt and manually drive, preventing because occurring that above-mentioned situation causes the generation of dangerous accident.
3. can control 5 group actor parts simultaneously; There is automatic deloading function; There is flow regulating function.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is front view of the present utility model;
Fig. 3 is right view of the present utility model;
In figure, 1-fuel tank, 2-reversal valve group, 3-manual pump, 4-unloader, 5-speed changing-over valve, 6-flow speed control valve, 7-overflow valve, 8-Pressure gauge, 9-liquid level takes into account thermometer, 10-hydraulic manifold block, 11-handle.
Detailed description of the invention
Be further described the utility model below in conjunction with accompanying drawing, protection domain of the present utility model is not limited to the following stated:
As Fig. 1, shown in Fig. 2 and Fig. 3, a kind of compact pumping plant, it comprises fuel tank 1, pump assembly closes, hydraulic manifold block 10 and reversal valve group 2, pump assembly closes and is arranged in fuel tank 1, described pump assembly closes and is made up of motor and oil pump, the output shaft of motor is connected with the rotating shaft of oil pump, hydraulic manifold block 10 is arranged on fuel tank 1 top, described hydraulic manifold block 10 is by overflow valve 7, unloader 4, speed changing-over valve 5 and flow speed control valve 6 form, a road manual actuation oil circuit and a road hydraulic circuit is connected in hydraulic manifold block 10, the manual actuation oil circuit of hydraulic manifold block 10 is connected to manual pump 3, the hydraulic circuit of hydraulic manifold block 10 is connected with oil pump and reversal valve 2 groups respectively.
Described fuel tank 1 is provided with liquid level and takes into account thermometer 9.
Described hydraulic manifold block 10 is provided with Pressure gauge 8.
Described manual pump 3 is provided with handle 11.
The course of work of the present utility model is as follows: starter motor, driven by motor operation of oil pump, be oil cylinder discharge pressure oil, and keep the oil pressure of oil cylinder to stablize by the overflow valve 7 on hydraulic circuit, thus the piston rod promoting oil cylinder is overhanging through output pipe; When hydraulic stem bounces back, speed changing-over valve 5 action on hydraulic circuit, by flow speed control valve 6 decrease speed, allows pressure oil get back to pumping plant fuel tank 1.Oil pump connects hydraulic manifold block through output pipe, oil circuit in hydraulic manifold block is connected to a road manual actuation oil circuit and a road hydraulic circuit successively, manual actuation oil circuit is connected with manual pump, when emergencies such as the unexpected power-off of motor or faults, can manually pump 3 through manual actuation oil circuit to pressure oil supercharging, thus pumping plant is normally worked.The side plate of fuel tank 1 is provided with liquid level and takes into account thermometer 9, make as hydraulic power unit security is high, workable, when hydraulic oil loss is more, the reliable and stable operation of can annotate to fuel tank 1 oil plant, guarantee hydraulic power unit.
