Abstract

The utility model provides a hydraulic oil heat-dissipating system for a wheel loader. The hydraulic oil heat-dissipating system comprises a gear pump, wherein the gear pump is connected with a multi-way valve; the multi-way valve is connected with a movable arm oil cylinder and a rotating bucket oil cylinder; the oil return port of the multi-way valve is connected with a temperature control valve, a safety valve and a radiator; the temperature control valve, the safety valve and the radiator are connected in parallel. By adopting the device provided by the utility model, the defects in the prior art are overcome, the flow and temperature of hydraulic oil flowing through the radiator are controllable, the heat-dissipating capacity of the radiator is fully utilized, and the radiator can be protected.

Description

A kind of hydraulic oil cooling system of wheel loader
Technical field
The utility model relates to a kind of hydraulic oil cooling system of wheel loader, belongs to loader technical field.
Background technique
At present, various wheel loaders on market, its hydraulic oil cooling system configuration is comparatively simple, generally by pipeline flow dividing or by flow, compared with the oil circuit of minor loop, passes through radiator, this configuration cannot be carried out temperature control and flow control, causes the heat dissipation potential of radiator to make full use of.
Model utility content
It is controlled that the technical problems to be solved in the utility model is to provide flow through flow and the temperature of radiator of a kind of hydraulic oil, guarantees the hydraulic oil cooling system of the wheel loader that the heat dissipation potential of radiator makes full use of.
In order to solve the problems of the technologies described above, the technical solution of the utility model is to provide a kind of hydraulic oil cooling system of wheel loader, it is characterized in that: comprise gear pump, gear pump connects multi-way valve, multi-way valve connects boom cylinder and rotary ink tank, multi-way valve return opening connects heat-operated valve, safety valve and radiator, and control valve, safety valve, radiator are connected in parallel.
When the hydraulic oil cooling system of a kind of wheel loader that the utility model provides is used, fluid is sent into multi-way valve through gear pump, control the action of boom cylinder and rotary ink tank.Multi-way valve oil return is cooling through radiator, by heat-operated valve and safety valve, controls by the flow of the fluid of radiator.
The hydraulic oil cooling system of the wheel loader that compared to existing technology, the utility model provides has following beneficial effect:
(1) by heat-operated valve control hydraulic oil flow through radiator oil mass number, when oil temperature is low, few hydraulic oil, by radiator, raises rapidly oil temperature, reaches the required optimum working temperature of machine;
(2) arrange after safety valve, the loop of large flow can be connected with radiator, guarantee that the heat dissipation potential of radiator makes full use of, when flow is excessive, safety valve is opened, and radiator is shielded.
The device that the utility model provides has overcome the deficiencies in the prior art, and flow through flow and the temperature of radiator of hydraulic oil is controlled, guarantees that the heat dissipation potential of radiator makes full use of, and can shield to radiator.
Accompanying drawing explanation
The hydraulic oil cooling system schematic diagram of the wheel loader that Fig. 1 provides for the utility model.
Embodiment
For the utility model is become apparent, hereby with a preferred embodiment, and coordinate accompanying drawing to be described in detail below.
The hydraulic oil cooling system schematic diagram of the wheel loader that Fig. 1 provides for the utility model, the hydraulic oil cooling system of described wheel loader comprises gear pump 1, gear pump 1 connects multi-way valve 2, multi-way valve 2 connects boom cylinder 3 and rotary ink tank 4, multi-way valve 2 return openings connect radiator 7, simultaneously heat-operated valve 5 in parallel and safety valve 6.
When the hydraulic oil cooling system of the wheel loader that the utility model provides is used, fluid is sent into multi-way valve 2 through gear pump 1, control the action of boom cylinder 3 and rotary ink tank 4.Multi-way valve 2 oil returns are cooling through radiator 7, by heat-operated valve 5 and safety valve 6, control by the flow of the fluid of radiator 7.
The advantage of the hydraulic oil cooling system of the wheel loader that the utility model provides is:
1, by heat-operated valve control hydraulic oil flow through radiator oil mass number, when oil temperature is low, few hydraulic oil, by radiator, raises rapidly oil temperature, reaches the required optimum working temperature of machine.
2, arrange after safety valve, the loop of large flow can be connected with radiator, guarantee that the heat dissipation potential of radiator makes full use of, when flow is excessive, safety valve is opened, and radiator is shielded.
