1. When extracted to the pump, you should first check whether there is damage in the transport process and loose parts, with the pump technical documentation and spare parts are complete. 2. Turn the cooling fan, check whether the rotation is easy and flexible, if there is stuck phenomenon should be excluded. 3. Should be placed in clean, cool and ventilated indoor use, and must be placed steady, non-tiltable. 4. Before starting the new pump, the oil pump plug on the oil pump housing should be removed and filled with the filtered lubricant. Check the pump once a month for the pumping position. Be sure to check the upper and lower limits of the oil gauge. ---- 200 hours after the new pump work. The lower part of the pump housing should be removed to drain the sewage screw to drain the dirty oil, and then clean the oil pool, put on a new oil, usually after every 1000 hours of oil change, the requirements of the lubricating oil: Because the pump temperature is high , Slide the unloading ring of the larger than the specific pressure, thus requiring high viscosity lubricating oil, moving parts to ensure good lubrication and sealing effect. Second, also requires a high flash point and a certain degree of anti-oxidation stability, the oil is not volatile, not easy to oxidation caused by coke, the use of air pump in the northern winter, the pump must be placed above freezing point 10 ° C environment to avoid Oil condensation, poor oil delivery caused serious damage to the accident. According to these requirements, the selection of lubricants grades are as follows: Winter: Compressor Oil No. 13 Summer: Compressor Oil No. 19 If you do not have these two oils, select the following performance indicators of the lubricating oil (l) Relative viscosity 20 ~ 24 ° E or Kinematic viscosity 150 ~ 180cst50 ° C (2) Flash point: greater than 200 ° C. (3) Freezing point: below -15 ° C. The ambient temperature should be above 10 ° C above the freezing point of the oil. ---- Summer can also be selected on the 20th aviation lubricants and diesel engine oil on the 20th; optional winter 14 diesel oil, 15 gas oil substitute 5. Note the direction of rotation of the pump must be with the pump on the steering sign Instructions in the same direction. 6. When the pump parked more than three months or just overhaul, pump should be allowed to run for half an hour empty, and then add the rated load test run for half an hour, if there is no abnormal circumstances before the machine can be used. 7. Piping: The inlet pipe connector is connected to the use site for vacuum suction by the hose; the exhaust pipe connector is connected to the use site for blowing compressed air; if the gas is used to receive the paper, Paper hose connected to the gas port. Piping must pay attention to all pipes and joints shall not leak and wrinkled, the pipe diameter can not be less than the pipe diameter, when the pipe is longer than 2 meters, the hose must be connected with a larger diameter. 8. The size of the vacuum and pressure can be adjusted by rotating the valve knob. When the air pump is delivered from the factory, both the adjustable widths have limited the rated load. When the air pump is found not to reach the rated load after long-term use or overhaul, remove the knob, loosen the set screw on the copper sleeve, The middle of the adjustment bolt, turn clockwise, the vacuum (or pressure) to reduce, on the contrary increased. 9. Every one to two months for use of the air filter, it is necessary to remove the trash so as not to cause blockage, causing the performance to deteriorate. The method is to loosen the travel button, remove the gland after the intake can be air filter, remove air filter, the brush with a brush to rub outside. Then use the compressed air blowing from the inside out, if found damaged, must be replaced. 10. Oil and gas separation network cleaned once a year. The method is to loosen the front and rear cover, remove the filter, wash and dry. 11. Cooling pipes clean once every six months. The method is to remove the pre-cover plate, you can remove most of the garbage, and then use compressed air to remove the remaining garbage. 12. The pins of the pin coupling should be inspected at least once every six months, and the damaged ones must be replaced. The method is to remove the retainer after removing the motor, you can replace the rubber ring. Assembly, the coupling between the two halves should be left l ~ 2mm gap. This can be seen from the square hole in the motor bracket, which should not touch the coupling halves anyway. 13. The pump should be washable once a year operation. During disassembly and assembly, pay attention to the following points: (1) Do not bump and scratch the machined surface, and do not bend and deform the rotor shaft and vane. (2) The inner and outer rings of the bearing should not be mismatched when assembling. The air cavity must be clean and dry with compressed air. No foreign matter should be mixed into the air cavity. The paper pad must be intact to avoid air leakage and the oil path must be unimpeded. Cylinder, rotor, vane, unloading ring, bearing and other friction surfaces are required to be coated compressor oil, the two unloading ring and the cylinder and the two into the pipe should be filled with compressor oil. Unloader ring should be flexible, slide in the groove should be tight fit, if the change into a new vane, the surrounding must be blunt. (3) after assembly must pay attention to the coupling between the two halves should leave 1-2mm gap. (4) The injected compressor oil must be filtered.
150m Laser Distance Meter long range measurement, high accuracy and stability. place the Laser Rangefinder at point A, press the ON button to activate the laser, aim the laser dot to Point B, and press the On button again to measure the distance between the two points. Point, shoot, get a measurement. Or hold the button down to get a continuous measurement as you move closer to or farther from your target.
Laser distance meter has a wide variety of applications in construction and industries.It is very useful and convenient to give accurate measurement of distance, area and volume especially in large areas such as rooms, apartments, buildings, real estates, factories, warehouses, gardens, roads, infrastructures.
