During test, first water swivel 40 bolt is arranged on testing table support 101 top, water swivel 40 pipe core reaches in the middle part of testing table support 101 and the coupling head 1032 of loading whirligig assembly 103 links up.
2) on-load pressure size is set and starts to add to protect and carry automatic control:
Need the test load size loaded according to water swivel 40 specifications and models and standard SY/T5530 table 4 regulation, the test pressure size with reference to the pressure load table of comparisons 302 correspondence sets the bound pressure of electro connecting pressure gauge 301.
Composition graphs 3-4, close air switch QF14 and air switch QF25, and power light 6, main operated motor stop pilot lamp 8, loading returns motor stopping pilot lamp 10, unloading pilot lamp 24 all lights, press loading and return electric motor starting button 33 and Jia Bao carries automatic control start button 34, auxiliary reclay K115 and auxiliary reclay K520 obtains electric, now electro connecting pressure gauge 301 force value is lower than the upper pressure limit value of setting, therefore auxiliary reclay K217 obtains electric, A.C. contactor KM416 obtains electric, loading returns motor 2011 and brings into operation, loading returns motor and stops pilot lamp 10 to extinguish, loading returns motor run indicator 9 and lights, time relay KT219 obtains electric, after time delay 5S, three-position four-way electromagnetic directional valve 1YA coil 21 obtains electric, hydraulic oil enters point flow throttle valve 2033 through the right position of three-position four-way electromagnetic directional valve 2035, the top land of two loading hydraulic cylinders 1031 is entered again respectively respectively through two hydraulic control one-way valves 2034, loading hydraulic cylinder 1031 starts to load loading rotating mechanism 1033, thus start to load to water swivel 40, load pilot lamp 22 to light, when pressure reaches the higher limit of electro connecting pressure gauge 301 setting, auxiliary reclay K318 obtains electric, auxiliary reclay K217 dead electricity, A.C. contactor KM416 dead electricity, it is out of service that loading returns motor 2011, loading returns motor run indicator 9 and extinguishes, and loading returns motor and stops pilot lamp 10 to light, time relay KT219 dead electricity, three-position four-way electromagnetic directional valve 1YA coil 21 dead electricity, testing table enters protects the state of carrying, and loads pilot lamp 22 and extinguishes, and protects a year pilot lamp 23 and lights.
Press to add to protect and carry after automatic control start button 34, under the control of electro connecting pressure gauge 301, load and return motor 2011 at system pressure lower than autoboot during the threshold pression arranged, automatically stop higher than during pressure upper limit, so move in circles; Electrothermal relay II 31 overload protective functions.
Said process achieves automatically to load and protect and carries, and intuitively can show the magnitude of load of loading, simple and convenient.
3) water swivel 40 loads operational test:
Press main operated motor start button 29, time relay KT111, A.C. contactor KM312 and A.C. contactor KM113 obtains electric, main operated motor 1021 star starts, after time delay, A.C. contactor KM312 power-off, A.C. contactor KM214 obtains electric, main operated motor 1021 triangle start, drive turbine worm reducer 1022, load whirligig assembly 103, water swivel 40 pipe core rotates together, main operated motor stops pilot lamp 8 to extinguish, unloading pilot lamp 24 extinguishes, main operated motor run indicator 7 lights, water swivel 40 formally starts to load operational test, electrothermal relay I 30 overload protective functions.
Along with the carrying out of operational test, bearing in water swivel 40 pipe core can break-in gradually, and on-load pressure can decline, now step 2) in automatically add to protect and carry and can restart, and hydrant 40 reloads to required pressure size, load operational test and proceed.
After terminating by SY/T5530 execution water swivel loading operational test, first press main operated motor stop button 28, main operated motor 1021 shuts down, press again to add to protect and carry automatic control stop button 35, if system pressure is between the bound pressure of setting, loading returns motor 2011 and is in off-position, cannot start, now can press loading and return forced motor start button 37, loading returns motor 2011 and starts, now press again and return crawl control knob 39, return pilot lamp 25 to light, the 2YA coil 27 of three-position four-way electromagnetic directional valve 2035 obtains electric, the work of left position, until loading hydraulic cylinder 1031 piston rod is slightly retracted, unclamp and return crawl control knob 39, hydraulic system unloads, owing to there is comparatively wide arc gap between coupling head 1032 and loading rotating mechanism 1033, so can not hydrant 40 Opposite side loading, piston rod stretches out point operation control button 36 can carry out the point operation control that loading hydraulic cylinder 1031 piston rod stretches out, and plays vacating space and handled easily when water swivel 40 pipe core is dismantled with coupling head 1032 or is connected.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
