Residual oil gear pump for conveying a variety of poor lubrication, the temperature does not exceed 200 ℃, viscosity greater than 1500cst medium, especially for the transport of medium containing fine particles have strong adaptability, such as residue, coal tar, floor oil, foam raw materials And additives containing edible oil delivery, pressure and so on. Pump body, pump cover, gear, shaft seal, gland, etc. The residue gear pump performance is good, tooth surface hard through special treatment, anti-torque force and so on. In the use of residue gear pump to refer to the following considerations for maintenance, to extend the service life of the pump: (1) residue gear pump in the handling process, should choose the appropriate lifting position to reduce the deformation of the pump. (2) The base of the residue gear pump should be fixed on a solid foundation so as to prevent the vibration from affecting the normal operation of the pump (3) Before the installation of the residue gear pump, check whether the pump and the motor are damaged during transportation, such as whether the motor Moisture, pump import and export of dust cover is damaged and so that dirt into the pump chamber and so on. (4) Inlet pipe should be designed with a separate bracket, the weight of the pipe may not have a pump to bear. (5) pump shaft and motor should be installed concentric, hand rotating coupling should be rotated evenly. (6) Import and export of pipe installation, the pipe wall should be cleaned with kerosene. (7) Import and export of gear pump gear pump diameter size not less than or greater than the diameter of the inlet pump, the inlet pipe should be as short as possible to reduce detours. Elbow bend radius should be as large as possible, into the oil pipe mouth should be cut into 45 bevels, to increase the cross-sectional area into the oil. When necessary, inlet pipe to be installed metal filter, the effective area of ​​the oil filter should be not less than three times the pipe diameter area. (8) Residual oil gear pump inlet and outlet at the factory closed to prevent dirt from entering, the installation should be removed from the dust cover. (9) Residual oil gear pump should be installed outdoors. When the temperature is lower than -5 ℃, external insulation measures should be taken to prevent the pump from cracking or affecting the normal operation of the pump.
Collated Nails
Common Nails designed with collated paper strip are mostly used as framing nails and Roofing Nails. It is made for quick uses and high efficiency works on the decking or flooring constructions. Normally the wire nails are hot dipped galvanized, or copper plated to enhance the corrosion resistance and beautiful outlook. The collating angles of the nails can be different while now mainly supplies four types: 34 degree, 28, 21, 17 degrees.
