BFZ coal mine sealing pump, BFZ-10 / 1.2 grouting sealing pump BFK-10 / 1.2 (2.4) mine grouting sealing pumps, BFZ-10 / 2.4 mine sealing pump, BFK Shanxi sealing grouting pump, BFZ-10 / 1.2 sealing pump, BFK-10 / 1.2,, BFK-10 / 2.4 BFZ-10 / 1.2 grouting sealing pump, a responsible person, said Zheng coal, each well-known companies will inevitably encounter the product has been copied, they also dogged. Due to lack of legal protection for the brand, BFZ-10 / 1.2 grouting sealing pump cause the value of the loss. Some characteristics of their own technology or innovative technologies being copied a few. In order to protect their intellectual property, Xi'an Coal also has thought of everything. BFZ-10 / 1.2 In addition to selecting the grouting pump sealing strengthen IPR protection (patents have been 66), perfect for trademark protection system, also developed a set of strict secrecy, design drawings, technology and other technical documents encryption, BFZ-10 / 1.2 grouting pump sealing and signed a confidentiality agreement with the technical staff. Xi'an Coal also by accelerating development and product replacement rate, and pirates robbed time. First, the structural characteristics and working principle of a major structural type BFK sealing pumps by proof motor, safety clutch, transmission systems, mixers, operate the clutch, sending pump and base composition of the two works ① stirred slurry when proof motor When in operational state, transmission system driven by a safety clutch moving blades rotating mixer, so to press the water-cement ratio requirement was added to the mixture within the mixer for continuous blending, mixing until uniform, to achieve the slurry was stirred. In the slurry mixing process, under the control of the clutch operating lever is in the disconnected state, sending pump is not running. ② The slurry after the slurry is stirred uniformly conveyed, the operation of the clutch lever in the clutch engagement state, at this time, the transmission system by the action of rotation of the clutch driven feed pump, feed pump during rotation of the suction depression The slurry within the mixer mixing the suction feed pump through the connecting pipe body, after the pressure from the outlet of the pump output, the completion of the slurry transportation. Send pump in operation, the mixer has been in rotation working condition. Second, the biggest feature: ① strong sealing capabilities: maximum sealing length of the horizontal drilling up to 30m or 40m, maximum sealing length of the vertical drilling up to 20m or 30m; ② both mixing, conveying high consistency pulp characteristics: for grout, which water-cement ratio reaches: slag cement, cement: water = 1: 0.32; Portland cement, cement: water = 1: 0.4; ③ treat seal without borehole section is expanded holes and the feed slurry pipe to the bottom of the borehole to be sealed, simply send in a slurry pipe to be drilled orifice seal properly fixed and can block; ④ Because of these characteristics, greatly simplifying the sealing process, reduce labor intensity sealing operations; ⑤ high consistency grout has almost no shrinkage, any drilling ensures sealing tightness, improve sealing quality borehole. BFZ mine grouting sealing pumps Description: BFZ mine grouting sealing pump (original BFK type) suitable for coal mine gas drainage sealing, seam water sealing, grouting sealing and other various types of drilling sealing. With automatic mixing function, quality and reliable sealing, sealing process is simple, easy to apply, easy to maintain. Model: BFZ-10 / 1.2, BFZ-10 / 2.4, BFK-10 / 1.2, BFK-10 / 2.4 Third, the major technical indicators: Model BFZ-10 / 1.2 BFZ-10 / 2.4 operating pressure range (MPa) 0 ~ 1.2 0 ~ 2.4 plugging depth (m) vertical 20 horizontal 30 vertical 30 horizontal 40 Dimensions (mm3) 1820 × 426 × 878 2120 × 426 × 878 Weight (kg) 170 170 output flow 8 ~ 10L / min motor work voltage of 380 / 660V motor power 4kW blender volume 30L flameproof electromagnetic starter operating voltage 380 / 660V Gast Jining Mining Equipment Co., Ltd. is committed to research and development of production of various mine pumps: pneumatic injection pump, pneumatic injection pump, dual hydraulic piston mortar pump piston injection pump, grouting machine, piston pumps, extrusion pumps, twin pump, mortar pump, mortar pump, manual injection pump, pneumatic submersible pumps, pneumatic submersible turbine pumps, wind-driven flushing sewage submersible pumps, submersible sewage pump squeeze-type injection pump, hydraulic injection pump,
