The pipeline cleaning can be cleaned with a clean towel soaked in the kerosene plug. The line is washed back and forth with the line. Finally, the kerosene is flushed into the pipeline for flushing. Except for no-clean lines). 3 installation of the pipeline interface. Card sleeve interface (see Figure 2 below). Technical delivery - machine room equipment installation - Cut the pipe to the required length. The deviation of the pipe section from the pipe centerline shall not be greater than half of the pipe outer diameter tolerance. - Clean the pipe, remove the burrs inside and outside the pipe end, and the metal chips, rust and dirt in the pipe. - Remove rust-proof oil and dirt from the parts of the ferrule joint. - Apply a small amount of lubricant to the cutting edge, threads and contact parts of the ferrule. - Firstly, the lock nut is placed on the pipe wall in order, and then the ferrule is placed on the ferrule, and the cutting edge of the ferrule faces the joint. - Insert the tube into the taper hole in the joint so that the end face of the tube must abut against the reaction hole in the joint body and place it on the ferrule. - Tighten the lock nut with an extended wrench while turning the tube until it stops, mark it, and then continue tightening the lock nut 1/2 to 1 turn to cut the ferrule edge into the outer wall of the tube. - Loosen the lock nut and inspect the edge of the ferrule about 5mm from the outer wall of the pipe. The position of the ferrule cannot be changed during the inspection and the cut mark of the spigot edge is a uniform ring. The ferrule cutting edge has been cut into the outer wall of the tube. - Finally tighten and tighten the pin nut. (2) The piping interface of the Beringer hydraulic pumping station is shown in Figure 1. Note: The pipeline interface of the Beringer hydraulic pump station in the two pipeline interface types of the hydraulic pump station (see Figure 1, 2) is simple in structure, reliable in sealing and convenient in operation and maintenance. 4 After the hydraulic oil is filtered (filtering accuracy is 0.02mm), please pay attention to the fuel tank. Pay attention to the maximum and minimum oil level mark of the dipstick. Inject the hydraulic oil into the cylinder. When the plunger of the cylinder lifts the car to the highest level (the plunger rod extends all the cylinder), the oil level in the tank should not be lower than the minimum oil level mark of the dipstick. After installing the oil cylinder, install the pipeline shut-off valve, the pipeline shut-off valve is connected with the oil cylinder, the oil pipe and the shut-off valve, the oil pipe and the oil pipe, the oil pipe and the pump station are all connected with the pipe joint, and the sealing ring should be placed inside the pipe joint, and the sealing ring can be installed first. Apply a little butter on the surface as a bonding agent into the fitting to facilitate installation. The line from the oil cylinder to the pumping station of the engine room should pursue the nearest distance. During this period, special attention should be paid to avoiding the position of the wire rope. After the oil pipe is connected, it should be fixed on the wall of the hoistway. Five, quality standards (1) Main control project: 1 The hydraulic pump station must be equipped with overload protection. The set pressure of the safety valve should not exceed 120% of the rated working load. 2 The hydraulic piping of the hydraulic system should be as short as possible. Pipe connections other than hydraulic stations shall be welded, welded flanges or threaded pipe joints, and shall not be assembled by shrink fitting or flared. 3 The rigid pipe in the hydraulic system piping should be a seamless steel pipe with sufficient wall thickness. The high pressure hose used between the hydraulic cylinder and the check valve or the down valve should have a safety factor of not less than 8 with respect to the burst pressure. The hose should be marked with the manufacturer's name, test pressure and test date. (2) General items: 1 The pressure gauge showing the working pressure of the system should be clear and accurate. 2 The hydraulic pump station oil level display should be clear and accurate. 3 The hydraulic pipeline should be reliably connected and fixed, and there is no leakage. 4 The use of hydraulic oil should be carried out in accordance with the manufacturer's regulations. Construction safety and finished product protection 1 The mechanical equipment of the equipment room is strictly prohibited from being damp and collided during transportation, storage and installation. 2 The doors and windows of the machine room should be complete and firm, and the machine room should be locked. Non-related personnel cannot enter the equipment room to prevent accidents. 3 There should be reliable fire prevention measures when using electricity and gas welding, and a special person should watch the fire. Seven, should pay attention to the problem 1 All the pipes and other components in the concrete shall be inspected by the quality inspector before the concrete is poured. When the requirements are met, the next process may be carried out after being signed by the inspector. 2 The hydraulic pump station is in the process of commissioning. It is found that there is an abnormal phenomenon. When it is necessary to dismantle the inspection and adjustment, the manufacturer should first check and handle it. If the manufacturer agrees, the technical department should work with the experienced engineer according to the relevant regulations. 3 Hydraulic elevators that do not use oil-immersed motors and screw pumps. In order to reduce noise in the equipment room, it is best to adopt sound insulation and sound absorption measures. 4 The hydraulic pumping station, electric control cabinet and its ancillary equipment of the hydraulic elevator must be installed in a dedicated room, which should have separate doors, walls, floors and ceilings. Items not related to the hydraulic lift must not be placed in it.
