Abstract
A pressure withstanding test device for a hydraulic oil cylinder comprises high-pressure ball valves and a pressure meter. The four high-pressure ball valves and the pressure meter are arranged at the upper part of an internal pressure cylindrical container; and one high-pressure ball valve is arranged at the lower part of the cylindrical container. A power pressure testing pump is connected with the high-pressure ball valve a by an oil inlet rubber pipe. The high-pressure ball valve d is connected with an opening A of a double-acting hydraulic oil cylinder by a pipeline rubber pipe. An opening B of the double-acting hydraulic oil cylinder is connected with an oil storage pool of the power pressure testing pump by an oil returning rubber pipe. A supporting frame is fixed at the lower part of the internal pressure cylindrical container. The pressure withstanding test device for the hydraulic oil cylinder is simple to manufacture, is convenient and safe to operate and has low manufacturing and test cost. Due to the pressure withstanding test device, a mechanical hydraulic oil cylinder can be tested, and performance detection on various hydraulic tube pipes and various valve bodies can also be carried out.
Description
Technical field
The utility model relates to a kind of hydraulic test equipment, particularly relates to a kind of hydraulic jack Withstand test device.
Background technique
The development machine maintenance, emphasis is the maintenance of hydraulic system, and oil hydraulic cylinder is a key component in the hydraulic system." MT/T 1097-2008 colliery electromechanical equipment service technique standard " 5.5.6.3 clause regulation: the development machine oil hydraulic cylinder will be 1.5 times of rated pressure test 5min, and inside and outside seepage can not be arranged.At present, what hydraulic jack manufacturer and maintaining unit carried out that testing property uses to oil hydraulic cylinder is Standard Test Rack, and this Laboratory Furniture can be used for every testing property (comprising tests such as life-span, withstand voltage, breakout pressure characteristic) of various oil hydraulic cylinders.And the development machine maintenance only needs oil hydraulic cylinder is done pressure test, and it is many unfavorable therefore to use Standard Test Rack to have: 1, these functions of the equipments are many, complex structure, operating process relative complex.2, it is higher to buy this cost of equipment, uses this equipment can increase the overhaul cost of development machine hydraulic jack again greatly.
The model utility content
The purpose of this utility model is the deficiency at prior art, provides a kind of simple in structure, making and user cost hydraulic jack Withstand test device low, easy and simple to handle.
The utility model hydraulic jack Withstand test device.Comprise internal pressure cylinder container, high-pressure ball valve, pressure gauge, a high-pressure ball valve, b high-pressure ball valve, c high-pressure ball valve, d high-pressure ball valve and a described pressure gauge are installed in wherein said internal pressure cylinder container top, an e high-pressure ball valve is installed in the bottom, the power hydraulic test pump is connected with described a high-pressure ball valve by the oil-feed sebific duct, described d high-pressure ball valve is connected with the A mouth of double-act-ing hydraulic J-Horner by the pipeline sebific duct, and the B mouth of described double-action liquid oil cylinder is connected by the oil storage pool of oil return sebific duct with the power hydraulic test pump.
The utility model hydraulic jack Withstand test device, wherein said internal pressure cylinder container bottom is fixed with a supporting frame.
The utility model hydraulic jack Withstand test device difference from prior art is that the utility model hydraulic jack Withstand test device is made simple, easy and safe to operate, and making and experimentation cost are low.This hydraulic jack Withstand test device also can detect various hydralic hoses and various valve body performance.
Below in conjunction with accompanying drawing hydraulic jack Withstand test device of the present utility model is described further.

Fig. 2 is the sealing internal pressure vessel side view of the utility model hydraulic jack Withstand test device.
Fig. 3 is the user mode figure of the utility model hydraulic jack Withstand test device.
Embodiment
As shown in Figure 1 and Figure 2, the hydraulic jack Withstand test device that the utility model provides utilizes high-pressure ball valve, the pressure gauge of finished product, provides a kind of brand-new design.Internal pressure cylinder container 6 is provided with 41,2,3,4 and pressure gauges 5 of a high-pressure ball valve, b high-pressure ball valve, c high-pressure ball valve, d high-pressure ball valve that specification is different in the hydraulic jack Withstand test device that the utility model provides, and is provided with an e high-pressure ball valve 8 below the internal pressure cylinder container 6.Internal pressure cylinder container 6 is fixed on the supporting frame 7.
As shown in Figure 3, oil-feed sebific duct 14 1 ends connect power hydraulic test pump 12 oil outlets that have pressure gauge 13, and the other end is mounted on a high-pressure ball valve 1 of internal pressure cylinder container 6.Pipeline sebific duct 9 one ends connect d high-pressure ball valve 4, and the other end connects the A mouth of development machine double-act-ing hydraulic J-Horner 10.Oil return sebific duct 11 connects the B mouth of development machine double-action liquid oil cylinder 10, and the other end connects the oil storage pool of power hydraulic test pump 12.
During use, at first open a high-pressure ball valve 1 and c high-pressure ball valve 4, close b high-pressure ball valve 2 and c high-pressure ball valve 3 and e high-pressure ball valve 8, the hydraulic test pump 12 that turns on the power is then suppressed, hydraulic oil enters in the A side chamber of development machine double-act-ing hydraulic J-Horner 10 by internal pressure cylinder container 6, hydraulic oil in the A side chamber can promote piston rod makes it stretch out to the B side, and B side intraluminal fluid presses oil to get back to the oil storage pool of power hydraulic test pump 12 by oil return sebific duct 11, so that recycle.Treat that oil is full in the A side chamber of double-act-ing hydraulic J-Horner 10, when continuing to suppress, pressure can constantly rise, when pressure gauge 5 and pressure gauge 13 force value reach 1.5 times of rated pressures of oil hydraulic cylinder, shut a high-pressure ball valve 1, pressurize 5min, whether have inside and outside seepage phenomenon, and can measure the piston rod stroke if observing double-acting hydraulic cylinder 10.(this container design pressure is greater than 1.5 times of development machine oil hydraulic cylinder rated pressures).
The utility model hydraulic jack Withstand test device can well be judged development machine oil hydraulic cylinder performance quality, guarantees development machine overhaul progress and quality.
Above-described embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection domain of the utility model claims.
