Technical field
The utility model is related to the domain of control temperature of stretching machine hydraulic oil, and in particular to a kind of hydraulic oil attemperating unit,
Realize stretching machine in stretching process to the temperature controlling function of hydraulic oil.
Background technology
Steel strand wires are put into component, tensioning is carried out to steel strand wires with stretching machine, component is produced deformation, i.e., in component
Stress is formed, to tackle the load that component is born.This process is prestressed stretch-draw, and the stretching machine used by it includes control
Circuit, fuel tank, valve group, hydraulic pump and jack etc..Need to be put into enough hydraulic oil in fuel tank, just can guarantee that the normal work of stretching machine
Make.
Before stretching machine work, the temperature and environment temperature of hydraulic oil are basically identical, with the increase of working time, hydraulic oil
Temperature be gradually increasing.When the temperature of the surroundings is low, the hydraulic fluid temperature that stretching machine is started working is also low, and environment temperature is higher
When, after stretching machine work a period of time, the temperature of hydraulic oil can be higher.
The hydraulic oil of different model has suitable operating temperature, when temperature is too high, hydraulic oil viscosity reduction, under lubricity
Drop, can increase in system and let out, and accelerate the oxidation of hydraulic oil, shorten the service life of hydraulic oil；Temperature is too low, hydraulic oil viscosity liter
Height, poor fluidity influences stretching machine normal work.Because use environment is different, analysis of hydraulic oil overheat or too low can be caused, it is right
The use of stretching machine causes restriction.
Utility model content
Technical problem to be solved in the utility model is to prevent stretching machine liquid in high temperature or low-temperature working environment
Force feed is too high or too low for temperature, causes stretching machine degradation, the use of final influence stretching machine.
To achieve these goals, the utility model provides a kind of hydraulic oil attemperating unit, including Electric Machine at Pumping Station, hydraulic pressure system
System, fuel tank, the heater being arranged on below fuel tank internal, the radiator being arranged on above fuel tank, the temperature being arranged in fuel tank
Sensor；The heater is used to be carried out when the temperature of the temperature sensor measurement is less than the minimum value of predetermined temperature range
Heating；The radiator is used to be dissipated when the temperature of the temperature sensor measurement is higher than the maximum of predetermined temperature range
Heat.
Preferably, the hydraulic oil attemperating unit also includes liquid level sensor, and the liquid level sensor is arranged on the oil
The bottom of case, the liquid level sensor is used to measure the liquid level in fuel tank, and is controlled when the liquid level of measurement is less than safety levels
The heater is closed.
Preferably, the temperature sensor includes temperature detection end, and the temperature detection end is located at the temperature sensor
Bottom, the bottom of the temperature sensor is located in the fuel tank, and the top of the temperature sensor is from fuel tank top
Stretch out.
Preferably, the heater uses dry combustion method sheath type heater.
Preferably, the temperature sensor is numeric type temperature sensor.
Beneficial effect is acquired by the utility model：
Stretching machine is controlled by devices such as heater, radiator, temperature sensor, liquid level sensors in the course of work
In, hydraulic oil is maintained in normal operating temperature range, hydraulic pump, reversal valve, check valve and overflow in protection hydraulic system
The Hydraulic Elements such as valve, extend the service life of hydraulic oil；
Liquid level sensor measures hydraulic oil liquid level.When hydraulic oil liquid level is less than safety levels, heater does not work, and prevents
Liquid level is too low during heating and something unexpected happened.Described device simple structure in itself, it is easy to install.
Brief description of the drawings
Accompanying drawing is further understood to of the present utility model for providing, and constitutes a part for specification, and following
Specific embodiment be used to explain the utility model together, but do not constitute to limitation of the present utility model.In the accompanying drawings：
Fig. 1 is the structural representation of the hydraulic oil attemperating unit that the utility model is provided：
