The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.
The utility model provides an integrated cooling pump set, which integrates a cooling water pump, a cooling oil pump, a gear motor and a control module, and drives the cooling water pump and the cooling oil pump to provide cooling water and cooling oil for a complete machine by providing high-pressure oil to the gear motor. Meanwhile, the integrated cooling pump set is monitored and controlled by integrating the control module on the end cover of the integrated cooling pump set. The integrated pump set utilizes the advantage of high energy density of the hydraulic motor and the design of coaxial driving to realize the driving and control of the water pump and the cooling oil pump in a smaller space.
The above-described integrated cooling pump assembly is further described below with reference to the accompanying drawings.
As shown in fig. 1 and 2, the cooling water pump is a centrifugal water pump 8 for providing cooling water for the whole machine, and the cooling oil pump is a gear pump 5 for providing cooling oil for the whole machine. The gear motor 3 and the gear pump 5 share two through transmission shafts, and the centrifugal water pump 8, the gear motor 3 and the gear pump 5 share one of the through transmission shafts 1. This drive mode reduces the torque transfer connection of the gear motor 3 to the centrifugal water pump and the gear pump, respectively, improves the drive efficiency, and reduces the size and weight of the pump stack.
With continued reference to fig. 1 and 2, the centrifugal water pump 8 and the gear pump 5 are arranged on two sides of the gear motor 3, the driving force generated by the gear motor 3 is transmitted to two sides through the driving shaft 1, one side drives the gear pump 5, and the other side drives the centrifugal water pump 8.
With continued reference to fig. 1 and 2, an electric proportional relief valve 6 and a rotation speed sensor 2 are disposed on the connection end cap of the gear motor 3. The oil inlet of the electric proportional overflow valve 6 is communicated with the oil inlet of the gear motor 3 through an end cover internal oil passage, and the oil outlet of the electric proportional overflow valve 6 is communicated with the oil outlet of the gear motor 3 through an end cover internal oil passage. The electric proportional relief valve 6 may control the inlet pressure of the gear motor 3 to control the rotational speed of the gear motor 3. The rotational speed sensor 2 is used for detecting the rotational speed of the driving shaft 1, namely the rotational speeds of the centrifugal water pump 8, the gear motor 3 and the gear pump 5, and is used for feeding back whether the working state of the integrated cooling pump set is under the control of the electric proportional overflow valve 6.
With continued reference to fig. 1 and 2, a detection port of a temperature sensor is provided at the outlet of the centrifugal water pump 8, and a water temperature sensor 7 may be installed to detect the temperature of the cooling water in real time, and determine whether the rotational speed of the integrated cooling pump unit is increased, decreased or maintained according to the cooling water temperature.
With continued reference to fig. 1 and 2, a detection port of a temperature sensor is provided at an inlet of the gear pump 5, and an oil temperature sensor 4 may be installed to detect the temperature of the cooling oil in real time, and determine whether the rotational speed of the integrated cooling pump unit is increased, decreased or maintained according to the oil temperature.
The further scheme is as follows: the rotation speed sensor 2 is also connected with an alarm component, and when the rotation speed sensor 2 detects that the rotation speed of the gear motor 3 is not under the control of the electric proportional overflow valve 6, a prompt is sent out through the alarm component.
The working principle of the integrated cooling pump set of the utility model is as follows:
With continued reference to fig. 1 and 2, after the vehicle starts, the electric proportional overflow valve 6 defaults to be in a maximum overflow pressure state, and when a small flow of high-pressure oil reaches the inlet of the gear motor 3, the driving shaft 1 is pushed to start rotating, and the driving shaft 1 drives the centrifugal water pump 8 and the gear pump 5, so that the integrated cooling pump set supplies cooling water and cooling oil to the whole machine at a maximum rotation speed. The rotational speed sensor 2 detects in real time whether the rotational speed of the drive shaft 1 is within a set interval.
When the oil temperature sensor 4 detects that the cooling oil temperature is lower than a certain set value and the water temperature sensor 7 is lower than a certain set value, the controller reduces the overflow pressure of the electric proportional overflow valve 6, so that the integrated cooling pump set reduces the rotating speed to supply cooling water and cooling oil to the whole machine. The rotational speed sensor 2 will detect whether the rotational speed of the drive shaft 1 starts to decrease by setting the electric proportional relief valve 6.
When the oil temperature sensor 4 detects that the cooling oil temperature is higher than a certain set value or the water temperature sensor 7 is higher than a certain set value, the controller increases the overflow pressure of the electric proportional overflow valve 6, so that the integrated cooling pump set increases the rotating speed to supply cooling water and cooling oil to the whole machine. The rotational speed sensor 2 will detect whether the rotational speed of the drive shaft 1 is increasing in accordance with the start of the set electric proportional relief valve 6.
When the rotational speed sensor 2 detects that the rotational speed of the drive shaft 1 does not correspond to the setting, the controller will issue a reminder.

In a third aspect, the utility model discloses an engineering vehicle provided with the integrated cooling pump set; or the cooling system described above is installed.
In some embodiments, the work vehicle comprises a mining dump truck.

For example, in the above embodiments, those skilled in the art can use the above embodiments in combination according to known technical solutions and technical problems to be solved by the present utility model.
