Abstract

A cooler water leakage on-line detection device comprises a cooler. The cooler is provided with a water-entering pipeline, a water-exiting pipeline, a corresponding water-entering valve and a corresponding water-exiting valve as well as an oil-entering pipeline, an oil-exiting pipeline, a corresponding oil-entering valve and a corresponding oil-exiting valve, wherein the water-entering pipeline is provided with a filter and a flow adjustment valve sequentially, and the water-exiting pipeline is provided with a water-return back pressure valve. The cooler water leakage on-line detection device further comprises an oil draining valve which is arranged at the bottom of the cooler, a first stop valve which is arranged on the water-entering pipeline of the cooler and is located before the water-entering valve, a pressurizing cylinder, a pressure gage arranged at the water-exiting pipeline of the cooler; an overflow valve which is arranged at a high-pressure end pipeline of the pressurizing cylinder, and a drain valve which is arranged at a lower-pressure end of the pressurizing cylinder, wherein the lower-pressure end of the pressurizing cylinder is connected with a pipeline between the water-entering valve and the first stop valve on the water-entering pipeline of the cooler through a pipeline and a second stop valve, and a high-pressure end of the pressurizing cylinder is connected with a pipeline behind the flow adjustment valve on the water-entering pipeline of the cooler through a pipeline and a third stop valve. With the cooler water leakage on-line detection device of the utility model adopted, water leakage of the cooler can be found timely; and equipment failure caused by a situation where a large quantity of cooling water enters an oil liquid can be avoided.

Description

A kind of water leakage of cooler on-line measuring device

Technical field

The utility model relates to hydraulically operated equipment (HOE), particularly a kind of water leakage of cooler on-line measuring device.

Background technology

Refrigeratory one of oily temperature adjusting device that is absolutely necessary in hydraulic system, refrigeratory can effectively reduce the temperature of hydraulic oil in the pipeline, makes its temperature control a reasonable range comparatively, satisfies the requirement that hydraulic system runs well.

In actual use, refrigeratory can cause because of various reasons and leak, and can cause hydraulic system fault after chilled water enters in the hydraulic oil, as: faults such as hydraulic valve is stuck, hydraulic pump damage.Certainly the reason that causes the hydraulic oil water inlet is more, for whether definite hydraulic oil water inlet reason is caused by refrigeratory that the method that adopts is at present: refrigeratory is separated device systems, carry out off-line and suppress the leak detection processing, judge whether it leaks.Because the method required time of off-line leak detection is longer, if the temperature of medium can not get effective control during the leak detection, will cause bigger influence to the stable operation of equipment, so this method generally overhaul of the equipments or inactive in adopt.

Summary of the invention

The purpose of this utility model is to provide a kind of water leakage of cooler on-line measuring device, only need the interim refrigerating function (general control detection time is within 30 minutes) that suspends, can realize online detection water leakage of cooler whether function, can in time find the water leakage of cooler situation, avoid a large amount of chilled waters to enter and cause equipment failure in the fluid, also eliminated the input of dismantling the required human and material resources of refrigeratory simultaneously.

For achieving the above object, the technical solution of the utility model is:

A kind of water leakage of cooler on-line measuring device comprises, refrigeratory, arrange on it water-in and water-out pipeline and accordingly into and out of water valve, into and out of oil pipe line and accordingly into and out of fuel tap; Also establish filtrator, flow control valve on the inlet channel successively; Also be provided with the backwater counterbalance valve on the outlet conduit; It comprises that also a draining valve is established in described refrigeratory bottom; Establish first stop valve on the refrigeratory inlet channel before the water intaking valve; Pressurized cylinder, its low pressure end is connected in the pipeline between the water intaking valve and first stop valve on the refrigeratory inlet channel by pipeline and second stop valve, and high-pressure side is connected in the pipeline behind the flow control valve on the refrigeratory inlet channel by pipeline and the 3rd stop valve; Described pressurized cylinder high-pressure side pipeline is also established surplus valve, and described pressurized cylinder low pressure end also is provided with draining valve; Tensimeter is arranged on the refrigeratory outlet conduit.

The beneficial effects of the utility model are:

The utility model is after hydraulic system is used, only need the interim refrigerating function (general control detection time is within 30 minutes) that suspends, can realize online detection water leakage of cooler whether function, can in time find the water leakage of cooler situation, avoid a large amount of chilled waters to enter and cause equipment failure in the fluid, also eliminated the input of dismantling the required human and material resources of refrigeratory simultaneously.

Description of drawings

Fig. 1 is the structural representation of the utility model embodiment.

Embodiment

Referring to Fig. 1, water leakage of cooler on-line measuring device of the present utility model, comprise that refrigeratory 1 arranges inlet channel 101, outlet conduit 102 and corresponding water intaking valve 2, outlet valve 3, in-line 103, fuel-displaced pipeline 104 and corresponding inlet valve, delivery valve on it; Also establish filtrator 4, flow control valve 5 on the inlet channel 101 successively; Also be provided with backwater counterbalance valve 6 on the outlet conduit 102; It comprises that also a draining valve 7 is established in described refrigeratory 1 bottom; Establish first stop valve 8 on the refrigeratory inlet channel 101 before the water intaking valve 2; Pressurized cylinder 9, its low pressure end 91 is connected in the pipeline between the water intaking valve 2 and first stop valve 8 on the refrigeratory inlet channel 101 by pipeline and second stop valve 10, and high-pressure side 92 is connected in the pipeline behind the flow control valve 5 on the refrigeratory inlet channel 101 by pipeline and the 3rd stop valve 11; Described pressurized cylinder 9 high-pressure sides 92 pipelines are also established surplus valve 12, and described pressurized cylinder 9 low pressure ends 91 also are provided with draining valve 13; Tensimeter 14 is arranged on the refrigeratory outlet conduit 102.

The work original state, second stop valve 10, the 3rd stop valve 11, draining valve 7 and draining valve 13 place closed condition.

When carrying out the water leakage of cooler inspection, at first close refrigeratory 1 in-line 103, fuel-displaced pipeline 104 into and out of fuel tap, open the draining valve 7 of refrigeratory 1, close outlet valve 3, open the 3rd stop valve 11 after opening draining valve 13, after treating that pressurized cylinder piston is got back to the end, close draining valve 13 again, close water intaking valve 2, open first stop valve 8, utilize pressurized cylinder 9 in refrigeratory 1, to suppress, required pressure is by surplus valve 12 regulation and control, after waiting that the pressure that reaches required requires, close the 3rd stop valve 11, enter packing state (general pressurize is about 15 minutes) at last.If pressure does not significantly descend between hold period, can represent that there is not drainage in refrigeratory 1, otherwise need to change refrigeratory.
