2CY gear pump to be used in a variety of mechanical equipment in the lubrication system for conveying lubricants. Working principle 1, the pump is not suitable for conveying dirty oil, it should be set at the inlet pipe filter 2, pump no safety valve, it is recommended in the drain line, set the safety valve to ensure the safe operation of the system. 3, the pump steering provisions: from the pump to the motor, the direction of rotation is counterclockwise. 4, the unit should be installed on the level of cement, with anchor bolts. 5, the installation height of the pump does not exceed the allowable suction height 6, the right coupling should be coaxial, the installation is complete, turn the coupling to confirm the smooth operation of negative pressure phenomenon, before entering operation. The pump Department of positive displacement pump, the main and passive gears and pump body, left and right pump cover into the oil, oil two enclosed space, when the gear is rotated, the volume into the oil chamber, as the meshing teeth continue to break away from small Bigger. The formation of a vacuum, the liquid inhalation, a tooth valley to the oil chamber, and the oil chamber volume, due to the meshing teeth continue to mesh and become smaller, the oil is compressed and discharged, so as to achieve the purpose of conveying oil. Structure This series of pumps mainly consists of: left and right pump cover, pump body, the main, passive gear shaft, sleeve, oil seal and other components. Use and installation 1, the steering pump requirements: From the pump to the motor, the direction of rotation is counterclockwise. 2, the pump is not suitable for conveying dirty oil, it should be set at the inlet pipe filter. 3, no pump safety valve, it is recommended in the drain line, set safety valve to ensure the safe operation of the system. 4, the right coupling should be coaxial, after installation is complete, turn the coupling to confirm the smooth operation without negative pressure phenomenon before entering the operation. 5, the unit should be installed on the level of cement, with anchor bolts. 6, the installation of the pump height, not to exceed the allowable suction height.
The main type of Tape Measure is Steel Tape, followed by fiber tape, which is the tape that everyone often sees. Many people say it is a cloth ruler, and there is also a waist measurement ruler (tailor ruler/clothing ruler belong to this category). In southern China and Hong Kong, the tape measure is usually referred to as a soft ruler or a pull ruler. The material is PVC plastic and glass fiber, which can prevent the tape from being stretched during use.
