Description
Technical field
The utility model relates to shield machine apparatus fields, specifically design a kind of pressure oil tank pressure warning unit.
Background technique
The system of applying pressure fuel tank on shield machine, such as assembling machine lifting system need to guarantee when lift cylinder stretches out
Oil liquid is sufficient, and oil pump has enough oil pressure, could normal segment assembly, if the insufficient pressure of pressure oil tank, or in use process
In, pressure oil tank forms negative pressure, and stored oil liquid is not able to satisfy oil pump and establishes pressure demand, will lead to, oil pump idle running, oil pump
Damage or the sealing of damage pressure oil tank and body structure.
Utility model content:
In view of the shortcomings of the prior art, the utility model one kind is provided can be in pressure oil tank insufficient pressure, when oil liquid is insufficient
It alarms, and carries out chain, the pressure oil tank pressure warning unit of protection oil pump and pressure oil tank with oil pump.
Technical problem to be solved in the utility model is realized using following technical scheme:
A kind of pressure oil tank pressure warning unit, including fuel tank, pressure switch, console, accumulator, oil pump, motor and
Overflow valve, the oil pump is mounted on fuel tank internal, and connect with the motor being mounted on outside fuel tank；The motor and console connect
It connects；Described pressure switch one end connects fuel tank, and one end connects console；The accumulator is connect with fuel tank；The overflow valve with
Fuel tank connection.
Further include filter as a kind of optimization of the utility model, the filter is mounted on fuel tank internal, and with oil
Pump connection.
As a kind of optimization of the utility model, fuelling coupling is also connected on the fuel tank.
As a kind of optimization of the utility model, blow vent is offered on the fuel tank.
A kind of pressure oil tank pressure warning unit provided by the utility model has following beneficial effect:
The pressure oil tank pressure warning unit of the utility model is the method by increasing pressure switch on pressure oil tank,
The pressure of pressure oil tank can be detected at any time, and the pressure value is fed back into console, after setting the pressure value of pressure switch, In
The pressure of pressure oil tank be lower than or more than setting pressure value when, the start and stop of oil pump can be forbidden, prevent oil pump from dallying, effectively
The performance for protecting oil pump, protects sealing and the body structure of pressure oil tank.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model pressure oil tank pressure warning unit.
Appended drawing reference: 1, fuel tank；2, pressure switch；3, console；4, accumulator；5, oil pump；6, motor；7, overflow valve；
8, filter；9, fuelling coupling；10, blow vent.
Specific embodiment
In the following, being described further in conjunction with attached drawing and specific embodiment to the utility model:
Shown in referring to Fig.1, a kind of pressure oil tank pressure warning unit, including fuel tank 1, pressure switch 2, console 3, accumulation of energy
Device 4, oil pump 5, motor 6 and overflow valve 7, the oil pump 5 are mounted on inside fuel tank 1, and with the motor 6 that is mounted on outside fuel tank 1
Connection；The motor 6 is connect with console 3；Described 2 one end of pressure switch connects fuel tank 1, and one end connects console 3；The storage
Energy device 4 is connect with fuel tank 1；The overflow valve 7 is connect with fuel tank 1.
It further include filter 8 as a kind of optimization of the utility model, the filter 8 is mounted on inside fuel tank 1, and
It is connect with oil pump 5.
As a kind of optimization of the utility model, fuelling coupling 9 is also connected on the fuel tank 1.
As a kind of optimization of the utility model, blow vent 10 is offered on the fuel tank 1.
Specifically, the pressure oil tank pressure warning unit of above-described embodiment is by increasing pressure switch 2 on fuel tank 1
Method can detect the pressure of fuel tank 1 at any time, and the pressure value is fed back to console 3, set the pressure value of pressure switch 2
Afterwards, the pressure in fuel tank 1 be lower than or more than setting pressure value when, the start and stop of oil pump 5 can be forbidden, prevent oil pump 5 from dallying,
The performance of effective protection oil pump 5 protects sealing and the body structure of fuel tank 1.
It will be apparent to those skilled in the art that can make various other according to the above description of the technical scheme and ideas
Corresponding change and deformation, and all these changes and deformation all should belong to the protection of the utility model claims
Within the scope of.
