Abstract
An engineering machinery sprinkling system with an overload protection function relates to the technical field of engineering machinery sprinkling, and solves the problem that a sprinkling nozzle is blocked to cause damage to a water pump; the problem of water pump damage has realized the overload protection function to the watering system pipeline because of the watering shower nozzle that causes of reasons such as the dust is too big, rivers impurity is too much blocks during having avoided the operation, and then leads to the watering system pipeline internal water pressure too high, simple structure, and the practicality is strong.
Description
Technical Field
The utility model relates to an engineering machine tool water system especially relates to an engineering machine tool watering system with overload protection function.
Background
Existing engineering machinery products (such as road rollers, milling machines and the like) are equipped with a water spraying system according to working requirements, and the system is shown in fig. 2. Namely, water reaches the sprinkling nozzle from the water tank through the joint, the pipeline, the water filter, the electric water pump and the sprinkling pipe, thereby realizing the sprinkling operation. Usually, the operation condition of the equipment is severe, so that the sprinkler head is easy to block. At this time, if the blocked spray head is not cleaned in time, the pressure of the water system rises sharply, and further the faults of burning insurance or burning the water pump are caused. Therefore, for the traditional water system, the sprinkler heads on the traditional water system need to be cleaned timely and regularly to ensure the safety of the water system. Although the problem of nozzle blockage is partially solved, the damage of components of a water system is easily caused due to negligence, untimely cleaning and the like, and a larger safety risk still exists.
Disclosure of Invention
In order to solve the problem, the utility model provides an engineering machine tool watering system with overload protection function provides one kind and effectively avoids causing the engineering machine tool watering system of the damage of water pump unit because of the reason of shower nozzle jam, carelessness, not in time clearance. In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides an engineering machine tool watering system with overload protection function, includes water tank, filter, water pump, three way connection, overflow valve and sprinkler pipe, the sprinkler pipe on be provided with the watering shower nozzle, the water pump be connected with the water tank through the filter, three way connection's water inlet is connected with the water pump through the pipeline, three way connection's delivery port is connected with the sprinkler pipe through the pipeline, the overflow valve be connected with three way connection's overflow mouth, the delivery port of overflow valve is connected with the water tank through the pipeline.
Further, the overflow pressure value set by the overflow valve is smaller than the rated working pressure of the water pump.
Furthermore, an overflow alarm sensor is arranged on the overflow valve, and workers are reminded of overhauling in time.
Compared with the prior art, the utility model discloses following beneficial effect has: both can satisfy the watering cooling, the dust removal requirement in engineering machinery equipment working process such as milling machine, road roller, can avoid again when the operation because of the dust too big, rivers impurity reason such as too much cause the watering shower nozzle block, and then lead to the watering system pipeline internal water pressure too high, the problem of water pump damage has realized the overload protection function to the watering system pipeline, simple structure, and the practicality is strong.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings.
FIG. 1 is a schematic structural diagram of the present invention;
fig. 2 is a schematic structural diagram of a sprinkler system of a conventional construction machine.
Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described with reference to fig. 1 and the specific embodiments.
As shown in the attached figure 1, the engineering machinery sprinkling system with the overload protection function comprises a water tank, a filter, a water pump, a three-way joint, an overflow valve and a sprinkling pipe, wherein a sprinkling nozzle is arranged on the sprinkling pipe, the water pump is connected with the water tank through the filter, a water inlet of the three-way joint is connected with the water pump through a pipeline, a water outlet of the three-way joint is connected with the sprinkling pipe through a pipeline, the overflow valve is connected with an overflow port of the three-way joint, and a water outlet of the overflow valve is connected with the water tank through a pipeline.
Further, the overflow pressure value set by the overflow valve is smaller than the rated working pressure of the water pump.
Furthermore, an overflow alarm sensor is arranged on the overflow valve, and workers are reminded of overhauling in time.
The utility model discloses a theory of operation and working process as follows: the water flow passes through the filter, the electric water pump, the three-way joint and the sprinkler pipe from the water tank and finally reaches the sprinkler head. Meanwhile, the overflow end of the three-way joint is connected with a P1 port of the overflow valve, and a P2 port of the overflow valve is connected with the water tank.
When the water sprayer works normally, water flows through the tee joint and is finally sprayed out by the water spraying nozzle to perform normal operation.
When the sprinkler head or the pipeline is blocked, the water pump still works continuously, the water pressure between the water pump and the sprinkler head is continuously increased at the moment, when the water pressure exceeds the overflow pressure value of the overflow valve, the P1 port and the P2 port of the overflow valve are communicated, and the water flow returns to the water tank through the overflow valve. Meanwhile, an operator can be reminded of timely checking and maintenance according to the overflow alarm sensor, and the equipment cannot cause the fault that waterway components such as a circuit or a water pump are damaged due to overhigh water pressure. Not only meets the working requirement, but also improves the safe reliability of the sprinkling system.
Utilize technical scheme, or technical personnel in the field are in the utility model discloses under technical scheme's the inspiration, design similar technical scheme, and reach above-mentioned technological effect, all fall into the utility model discloses a protection scope.
