Description
Technical field
The utility model belongs to automobile fuel pump class testing field, is related to a kind of lossless heating unit of fluid.
Background technology
In automobile fuel pump class testing field, to simulate real vehicle state, need to control the temperature of test oil in many cases.
Conventional oil heating unit is using electric heater for heating, and in heating process, heating pipe surface inevitably generates part
High temperature, high temperature can destroy oil, and form carbon distribution in heating pipe surface, influence the efficiency of heating surface；Another mode is by adding
The mode of thermal conductivity deep fat and heat exchanger carries out indirectly heat, and the apparatus structure is complicated, poor reliability, under continuous temperature shock
Easily there is oil leakage phenomenon.
Utility model content
The purpose of this utility model is exactly to solve the above-mentioned problems, to provide a kind of fluid lossless heating unit, it is not
Quick uniform accurately heats under the premise of damage Oil Quality.
The utility model can be achieved through the following technical solutions：A kind of lossless heating unit of fluid, including variable-frequency motor, is followed
Ring pumps and overflow valve, and the variable-frequency motor and circulating pump power connector, the inlet of the circulating pump access fluid by pipeline
In the fluid of container, the liquid outlet of the circulating pump is connected by pipeline with the inlet of overflow valve, and the overflow valve goes out liquid
Mouth is accessed by pipeline in the fluid of oil container.
Preferably, further include control device, the temperature sensor for sensing oil liquid temperature, the control device respectively with
Temperature sensor and variable-frequency motor electrical connection.
Compared with prior art, the utility model has following advantageous effect：The lossless heating unit profit of the utility model fluid
The hydraulic energy of fluid is converted into thermal energy with pressure quick release manner, high-voltage oil liquid pressure is discharged by overflow valve and generates heat
Can, it realizes the heating to fluid, avoids localized hyperthermia's situation；The flow pumped by variable-frequency motor control loop realizes heating work(
The step-less adjustment of rate；And all Hydraulic Elements may be arranged in fuel tank, and it is exposed outside fuel tank without pipeline, high temperature is avoided to rush
Occurs pipeline oil leakage phenomenon under hitting；In addition, the utility model also has manufacturing process simple, of low cost, control is simple, operation
Conveniently, the advantages that dependable performance, suitable for being widely popularized utilization.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Reference numeral
1 is variable-frequency motor, and 2 be circulating pump, and 3 be overflow valve, and 4 be oil container, and 5 be temperature sensor, and 6 fill in order to control
It puts.
Specific embodiment
The embodiment of the utility model is described in further detail below in conjunction with the accompanying drawings.
Referring to Fig. 1, a kind of embodiment of the lossless heating unit of fluid, including variable-frequency motor 1, circulating pump 2 and overflow valve 3,
The variable-frequency motor 1 and 2 power connector of circulating pump, the inlet of the circulating pump 2 access the fluid of oil container 4 by pipeline
In, the liquid outlet of the circulating pump 2 is connected by pipeline with the inlet of overflow valve 3, and the liquid outlet of the overflow valve 3 passes through pipe
In the fluid of road access oil container 4.The overflow valve 3 sets up system pressure, the stream of 1 control loop of the variable-frequency motor pump 2
Amount, heating power is controlled under the premise of pressure is certain.
Further include control device 6, the temperature sensor 5 for sensing oil liquid temperature, the control device 6 respectively with temperature
Sensor 5 and variable-frequency motor 1 are electrically connected.5 feedback signal of temperature sensor controls frequency conversion to control device 6, control device 6
Motor 1 realizes the closed-loop control of the lossless heating of fluid.
The course of work is as follows：
According to technique needs, 3 pressure of overflow valve is set up, that is, determines maximum pressure, pressure is once set up, variable-frequency motor 1
Output torque just determines that variable-frequency motor 1 exports different power, the portion of energy is by overflowing with different rotational speeds substantially
Stream valve 3 is converted into the thermal energy of fluid, realizes heating function, temperature sensor 5 is in real time to system feedback Current Temperatures as system
The foundation of temperature control.
In addition, the power of the utility model transformation variable-frequency motor 1 and the pressure rating of circulating pump 2, can significantly alter
Heating power.It can be by being transformed present apparatus seriation to be suitable for different occasions, consequently facilitating product seriation.
It should be noted that above example is merely intended for describing the technical solutions of the present application, but not for limiting the present application, this field
It is to be appreciated by one skilled in the art that can be modified or replaced equivalently to the technical solution of the utility model, without de-
Objective and range from technical solutions of the utility model, should all cover in the right of the utility model.
