SU1318887A1 - Device for detecting water traces in quenching oil - Google Patents

Abstract

The invention relates to a measurement technique, namely, devices for controlling the quality of quenching oils, and can be used to control the quality of heat treatment of bearing parts in mass and large-scale production. The aim of the invention is to increase accuracy and speed. The device contains a measuring chamber, in the lower part of which there is an oil heater nozzle and a first temperature sensor, and in the upper part of the chamber opposite the nozzle there is a second temperature sensor with the possibility of adjusting its height. The oil heater, located under the chamber, is connected to a constant pressure line consisting of a pump and a bypass channel. The outputs of both temperature sensors are connected through a comparison circuit with the logic circuit I. In this case, the oil heater is made in the form of a conductive tube, the ends of which are connected to a power source. The device provides reliable automatic detection of traces of water in the hardening oil and safety of deformation-free quenching of parts. 1 ZoPo f-ly, 1 ill. i (L with N1 00 00 00 -sj

Description

The invention relates to a measuring technique, namely, devices for monitoring (diagnosing) the quality of quenching oils, and can be used to control the quality of the set point U ,, and the output is fed to the machining of bearing parts in mass and large-scale production.

The aim of the invention is to increase

logical scheme and 19.

The signal from sensor 8 through the conversion circuit 16, showing the device J7 and the comparison circuit 18, also reveals the accuracy and speed variation, and goes to the logic circuit I. Thus, the boiled oil of traces is trapped at once, when the circuits are triggered

The drawing shows a diagram of the device for the automatic control of traces of water in the quenching oil,

The device includes an inlet pipeline 1, a pump 2, a throttling pipe 3, a tubular electric heater 4, a voltage regulator 5, a measuring chamber 6, a drain pipe 7, a temperature sensor 8, a nozzle 9, a measuring line 10, a temperature sensor 11, a screw 12 a height setting, a signal conversion circuit 13, showing the device 14J, a comparison circuit 15, a conversion circuit 16, showing the device 17, a comparison circuit 18, an AND 19 circuit and a software control device 20,

The device works as follows

Through the inlet pipe 1, the pump 2 pumps oil from the quenching tank, part of which is drained through the drain pipe 3 into the tank, and part enters the tubular electric heater 4 connected via voltage regulator 5 to the power grid. The output from the electric heater enters the chamber 6, in which the nozzle 9 forms a stream of oil.

The temperature of the escaping oil is monitored by a temperature sensor 8. At a height corresponding to the height of the jet of oil containing an unacceptable percentage of water, a temperature sensor 11 is installed using a height adjustment screw 12. If the jet of oil has reached the set height, the temperature sensor will generate a signal which is amplified by the conversion circuit 13, is fed to the indicating device 14 and to the comparison circuit 15, to the second input of which is supplied, sig15

No 15 and 18, circuit 19 will signal that there are traces of water in the quenching oil. If no trace of water is found, program control circuit 20 will turn off all the components of the device and turn it on again after a set time interval

The proposed device provides accurate and reliable automatic detection of traces of water in the quenching oil and eliminates the occurrence of a marriage for this reason, as well. also ensures the safety of deformation-free hardening of parts.
