The installation of the countertop basin is easy, as long as the hole is opened on the countertop. There are a variety of sink edge designs for over-counter basin sink styles to choose from. It is necessary to ensure that the connection gap between the sink and the countertop is uniform, and there is no water seepage.

Single screw pump selection points
Single-screw pump selection points 1. Single-screw pump pressure to determine: Single-screw pump maximum output pressure is based on the number of bushings that the number of bushings to determine: Level 1: the maximum working pressure of 0.6 MPa; Level 2 : The maximum working pressure is 1.2 MPa; Level 4: The maximum working pressure is 2.4 MPa; Due to the different conditions of the conveying medium, for the medium containing severe abrasion, please refer to Table 1 to select the liner series. Table 1: According to the choice of the wear of the liner series Bushing wear A secondary No 0.6MPa 1.2MPa General 0.4MPa 0.8MPa Severe 0.2MPa 0.4MPa 2. Single screw pump speed selection: Single screw pump due to its structural features , Most of them are used to transport liquids with higher viscosity and particles containing liquids. Therefore, the selection of the number of revolutions is very crucial. Based on experience, we can list Table 2 and Table 3, and you can consider them according to the specific conditions. Table 2: Select the speed of the pump according to the wear of the medium Abrasion resistance Name of medium Speed ​​(rpm) No fresh water, coagulant, oil, juice, meat foam, paint, soapy water, blood, glycerol 400-1000 General slurry, , Industrial waste water, paint pigments, waste water (sugar), mortar, fish, wheat bran, rapeseed oil Filtered sediment 200-400 Serious stone mortar, clay, plaster, clay 50-200 * The particular medium being transported and its special characteristics of wear and tear, please note that the characteristics of the medium with its concentration and temperature changes. * When the pump size is large, the speed should be selected lower. Table 3: Selection of pump speed according to medium viscosity Media viscosity (cst) 1-1000-100000 100000- 1000000 Speed ​​(rpm)-400 * In the choice of speed should also be based on experience, because of some other factors Also affect the choice of speed, in the final determination of the above values ​​at the same time, it is best to consult with the manufacturer. 3. Single screw pump bushing rubber material selection: Single screw pump bushing rubber products, but also a single screw pump wearing parts, and its choice of good or bad, directly affect the life of the bushing, under normal circumstances bushing The life of 3-6 months, if used improperly, the bushing may fall off from the pipe or rubber blocks. So ask us to understand the basic characteristics of rubber and rubber adaptability to different media, according to our experience listed in Table IV, Table V.
