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. 3M Tape Measure,Vintage Tape Measure,Cheap Tape Measure,Durable Steel Measuring Tape Henan Liangjin Tools Co.,Ltd , https://www.jtapemeasure.com

1. Increase the pressure of the gas seal; adjust the compression spring fuller pump in operation; the tongue valve needs to be continuously switched. When the tongue valve is opened; that is, when discharging, there must be some low pressure compressed air to transport the material. Break into the discharge chamber. Because some of the cylinders have longer spirals; the resistance is larger; so some compressed air is not easy to smash into the lowering funnel. The only future is through several rubber rings in front of the discharge end bearing. Bearing direction discharge. When the gas seal pressure is low; can not resist this air flow; it will bring raw powder into the bearing; form bearing heat. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
In order to deal with this problem; it is necessary to increase the pressure of the gas seal; at least it should be greater than the pressure of the compressed air to transport the material. Others; it is necessary to adjust the tightness of the compression spring of several sealing rubber rings. Wear; the bearing is still simple to heat, too loose; the rubber ring will not seal the effect; easy to make the raw meal into the bearing.
2. The axial clearance of the movable bearing is necessary to ensure that the screw shaft of the Fuller pump is usually long; take the diameter of the 300 Fuller pump as an example; the total length of the screw shaft of the pump is 3155 mm; the interval between the two fulcrums is considered to be 2800 mm; The difference is calculated at 30 ° C, 40 ° C and 50 ° C; then the thermal elongation of the screw shaft is: 0. 950, 1.266, 1. 582 mm. Such a large elongation; it is necessary to have in the two bearings One is the movable bearing. According to the drawing guidelines; usually the movable bearing is installed at the discharge end; and it is necessary to ensure the axial clearance; otherwise, the bearing will be heated. Therefore, the minimum between the outer end cover of the bearing end and the bearing at the discharge end should be left. 2 mm or so gap.
3. The amount of oil in the bearing should be properly adjusted for the bearing; it will also form the bearing heat.
For the normal rolling bearing grease smooth; should participate in 1/2 ~ 2 / 3 bearing space volume of grease. Too much grease; bearing will be hot, too little; one will shorten the working cycle; make the fueling cycle frequent; Fever due to lack of oil.
