Embodiment 1
[0063] This embodiment provides a system for keeping the solvent oil in a turbulent state for parts flushing, such as figure 2 As shown, it includes an operating table 1, a heat exchange subsystem, a temperature control subsystem, a solvent oil circulation subsystem, a water circulation subsystem and a controller, and each subsystem is connected to the controller for coordinated control.
[0064] The operating table 1 provides an operating space for parts flushing, for example, the operating table 1 is provided with a flushing gun head for flushing the parts to be flushed.
[0065] The heat exchange subsystem is used for heat exchange, that is, the heat of the water in the water cycle is uniformly and stably transferred to the solvent oil circulation subsystem, thereby realizing the temperature control of the solvent oil, wherein the heat exchange subsystem at least includes a water / oil heat exchanger 2 , Specifically, the water / oil heat exchanger 2 is a tubular structure.

Embodiment 2
[0083] This embodiment provides a method for washing parts with solvent oil in a turbulent state, which is implemented by using the system provided in Embodiment 1 above. Specifically, the solvent oil selected for flushing in this embodiment is IsoparL , and its physical properties such as image 3 As shown, according to the liquid viscosity-temperature characteristic equation:
[0084] Vogel equation:
[0085] in:
[0086] is the viscosity at temperature T, is the temperature T 0 The viscosity at , b is a constant, θ is the infinite viscosity temperature, and it can be taken as 95 for standard mineral oil;
[0087] So according to T=25℃: When T=40℃:
[0088] inferred:
[0089] Then the graph of viscosity and temperature is obtained as Figure 4 shown;
[0090] Further, when the flow rate is 1m / s and the pipe diameter is 8mm, the viscosity and Reynolds number of solvent oil at each temperature are shown in the following table:
[0091] temperature...

Abstract
The invention provides a system and method for washing parts by keeping solvent oil in a turbulent state. The system includes an operating table, a heat exchange subsystem, a temperature control subsystem, a solvent oil circulation subsystem, a water circulation subsystem and a controller. The heat exchange subsystem includes at least a water / oil heat exchanger, the solvent oil circulation subsystem includes an oil tank, an inner circulation loop and at least one outer circulation loop, and the water circulation subsystem includes a water tank, a heater, a water pump unit, a water circulation output pipe and a water circulation The return pipe, the water with the required temperature in the water circulation subsystem transfers heat to the solvent oil in the inner circulation loop through the water / oil heat exchanger to keep it within a specific temperature range, and the outer circulation loop outputs the solvent oil and forms a turbulent flow. The invention adopts solvent oil in turbulent flow state for flushing, and has the advantages of high flushing efficiency and good flushing effect.
Description
technical field [0001] The invention belongs to the technical field of parts flushing, and in particular relates to a system for keeping solvent oil in a turbulent state for flushing parts; at the same time, it also relates to a method for keeping solvent oil in a turbulent state for flushing parts. Background technique [0002] The excess in precision parts is the main cause of accidents, and washing the parts clean can greatly reduce the failure rate. [0003] The existing flushing system mostly adopts the structure of oil tank, pump and operating table. There is a water gun with a switch on the operating table. When the water gun is turned on, the flushing agent (solvent oil) is pumped out at a certain flow rate to flush the workpiece, and the flushing agent that has washed the workpiece passes through. The recovery line returns to the flushing agent tank. [0004] The prior art has the defects of unsatisfactory flushing effect and great influence by external factors, an...
