Abstract
A high-pressure cleaning machine with pressure-driven water supply comprises a high-pressure pump driven by a motor, and is characterized in that a low-pressure water supply pump (2) is connected in front of a water inlet of the high-pressure pump (5), and an adjusting valve (3) and a water supply pressure gauge (4) are connected in the back of the low-pressure water supply pump (10). The high-pressure cleaning machine can overcome the problem that damage can be caused to the high-pressure pump due to the insufficient water supply of the high-pressure pump, can supply water to the high-pressure pump continuously, stably and sufficiently, utilize a water supply valve to adjust water supply capacity according to requirements, read the water supply pressure from the water supply pressure gauge, and ensure that cavitation and high temperature cannot be caused to the high-pressure work parts of the high-pressure pump, and therefore the service life and work performance of the high-pressurepump are improved.
Description
Technical field
The utility model relates to water supply or cleaning equipment, is specifically to press the jetting machine that supplies water a kind of having.
Background technology
Cleaning Technology by High Pressure mainly is to produce water under high pressure with high-pressure pump to carry out work such as scrubbing, rust cleaning, cleaning through nozzle in various fields such as oil, chemical industry, machine-building, airport, road, rubber, electric power.At present tap water supply and cistern water supply are mainly adopted in the water supply of high-pressure pump, but insufficient water takes place, produce problems such as steam bubble, make high-pressure pump high-pressure work parts produce cavitation erosion, high temperature and reduce the life-span and the service behaviour of high-pressure pump through regular meeting.
Summary of the invention
The purpose of this utility model provides presses the jetting machine that supplies water a kind of having, overcome the high-pressure pump insufficient water, thereby high-pressure pump is produced the problem of infringement, make that high-pressure pump can access continuously, stablizes, the water supply of capacity, guarantee the high-pressure pump operate as normal, improve high-pressure pump service life and service behaviour.
Press the jetting machine that supplies water described having, and comprises by the high-pressure pump of driven by motor, it is characterized in that: be connected to the low pressure supply-water pump before the water inlet of high-pressure pump.Make the low pressure supply-water pump pump the water of certain flow and pressure, to guarantee that high-pressure pump can obtain continuously, stablizes, the water supply of capacity.
As prioritization scheme of the present utility model, the utility model also can be done following improvement: be connected to control valve and pressure of supply water table behind described low pressure supply-water pump.
Before described low pressure supply-water pump, be connected to filter.
On the pipeline behind the described high-pressure pump, be connected to safety valve and pressure regulator valve.
The utlity model has following advantage:
1, can be continuously, the supplying water of stable, capacity to high-pressure pump;
2, can regulate output with feed water valve as required;
3, can read pressure of supply water from the pressure of supply water table;
4, can guarantee that high-pressure pump high-pressure work parts do not produce cavitation erosion, high temperature, thereby improve the life-span and the service behaviour of high-pressure pump.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: the 1-filter, 2-low pressure supply-water pump, the 3-control valve, 4-pressure of supply water table, the 5-high-pressure pump, the 6-safety valve, the 7-pressure regulator valve, the 8-high pressure goes out water meter, 9-high-voltage tube, 10-water inlet, 11-motor.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified: have as shown in fig. 1 and press the jetting machine that supplies water, comprise the high-pressure pump 5 that drives by motor 11, before the water inlet of high-pressure pump 5, be connected to low pressure supply-water pump 2.Make low pressure supply-water pump 2 pump the water of certain flow and pressure, to guarantee that high-pressure pump 5 can obtain continuously, stablizes, the water supply of capacity.Prevent high-pressure pump 5 high-pressure work parts from producing cavitation erosion, high temperature and reduce the life-span and the service behaviour of high-pressure pump 5.
As prioritization scheme of the present utility model, the utility model also can be done following improvement: be connected to control valve 3 and pressure of supply water table 4 behind described low pressure supply-water pump 2.Reading according to pressure of supply water table 4 is transferred control valve 3, and the discharge pressure of low pressure supply-water pump 2 is remained in the suitable scope.
Before described low pressure supply-water pump 2, be connected to filter 1.Impurity during filter 1 can filtering supplies water, protection high-pressure pump 5 is avoided damage.
On the pipeline behind the described high-pressure pump 5, be connected to safety valve 6 and pressure regulator valve 7.Safety valve 6 is no more than setting pressure with protection high-pressure pump 5 to guarantee high-pressure pump 5 pressure, and pressure regulator valve 7 can be set the discharge pressure of high-pressure pump 5.
The water inlet 10 that is connected to filter 1 connects running water or water tank, pump the water of certain flow and pressure through low pressure supply-water pump 2, regulate pressure and flow through control valve 3, and process pressure of supply water table 4 is read pressure of supply water, be supplied to high-pressure pump 5, water under high pressure process pressure regulator valve 7 pressure regulation through high-pressure pump 5 pumps go out water meter 8 by high pressure and can read pressure, connect nozzle or high-pressure work devices by high-voltage tube 9.
