After the opening and closing equipment arrived at the construction site, should according to the DL/T5019-94 "water conservancy and hydropower project opening and closing mechanism building installation and acceptance standard" (hereinafter referred to as the "DL/T5019") regulations to conduct a comprehensive inspection, after inspection, before being installed. 2 check the foundation screw tied embedding location, bolt embedment depth and the length of the part should be accurate. Three should check the hoist platform height, its deviation should not be greater than + / - 5 mm, horizontal deviation should not be more than 0.5/1000. According to lifting hoist installation should center alignment, the transverse and longitudinal center line of deviation shall not be more than + / - 3.0 mm. Five winding length of wire rope on the drum, when the lifting point on the lower limit position, left on the drum number should not be less than 4 times, when lifting point position in cap, not winding wire rope to the light of the reel drum. Six pairs of lifting point hoist crane distance error should not be more than + / - 3.0 mm; Wire rope tension, the hoisting shaft centerline should be on the same level, the elevation difference within the orifice shall not exceed 5.0 mm. Seven crane electrical equipment installation shall comply with SD315-93 "fixed winding type hoist general technical conditions" of the relevant provisions. Before eight electric power test should carefully check all wiring and should comply with the regulations of design, the whole circuit of the insulation resistance must be greater than 0.5 M Ω just can start to test. Test in various motors and electrical components temperature rise shall not exceed their respective housings, test the machine's own electrical equipment should be adopted. Test if the first element in a burning, should find out the reason and to replace. Nine full hoist no-load test stroke should be upper and lower lifting three times. For electrical and mechanical parts of the following should be checked and adjusted. 1 motor running should be smooth, three phase current balance should not be more than + / - 10%, and should be measured current value. 2 electrical equipment should be no abnormal fever phenomenon. 3 should check and debugging limit switch (including the filling level of the opening of the pressure contact), switch action should be accurate and reliable. 4 height indicator and load indicator should accurately reflect the stroke and the weight, arrived at the upper and lower limit position, command switch should be able to signal and automatically cut off the current, make the opening and closing machine stop running. 5 all mechanical parts during operation, there should be no impact and other abnormal sound; At any location shall be friction with other components. 6 brake shoe brake should be opened entirely, clearance should comply with the requirements, and loose brake current value is measured. 7 for loose lock gate hoist using dc current, should be checked and recorded respectively loose brake dc current value and the temperature of the brake electromagnetic coil lasts 2 min. Ten hoist load test, the gate should be no water inside the gate slot or static water whole trip lifting up and down 2 times; For the work of moving water opening and closing valve or gate closed hydrostatic and dynamic water accident, should be the design head moving water lifting 2 times, under the condition of the pumping station exit gate, where should be the design head moving water conditions, the whole trip down quickly test. Load test should check electrical and mechanical parts of the following: 1 motor running should be smooth, three phase current balance should not be more than + / - 10%, and the current value should be measured. 2 electrical equipment should be no abnormal fever phenomenon. 3 all protection device and the signal should be accurate and reliable. 4 all mechanical parts in the operation should not be rushing sound, open gear meshing condition should comply with the requirement. 5 brake should be no sliding, no coke flavour and no smoking. Six load indicator and height indicator reading should be able to accurately reflect the gate under different opening of hoisting load values, the error must not exceed + / - 5%. 7 for quick gate hoist quick opening time shall not exceed 2 min; Quickly close the maximum speed of not more than 5 m/min. Maximum speed motor (or speed) shall not be more than twice the rated speed of the motor. The centrifugal governor of friction surface, the highest temperature should not exceed 200 ℃.
