BFK-type sealing pump 
 Pump pump sealing underground mine sealing pump sealing 
 I. Overview of the pump sealing 
 BFK-type pump is designed for sealing underground mine sealing all types of drilling equipment developed, and its biggest feature is: 
 ① sealing ability: the sealing of the maximum length of horizontal drilling of up to 20m, the vertical sealing on the maximum length of the drilling of up to 15m; 
 ② At the same time with the stirring, transport characteristics of high-consistency pulp: for cement, the water-cement ratio to achieve: slag cement, cement: water = 1:0.32; Portland cement, cement: water = 1:0.4; 
 ③ need to carry out the reaming drill towards closure and the slurry pipe to be sent to the bottom of borehole closure, just to get slurry pipe to be sealed in the appropriate orifice drilling and sealing can be fixed; 
 ④ Because of these characteristics, greatly simplifying the sealing process, reducing the labor intensity of sealing operations; 
 ⑤ high consistency slurry does not shrink with the basic nature of any drilling can ensure tight sealing, and improve quality of sealed borehole. 
 Second, BFK-type sealing structure and working principle of the pump 
 1. The main structure of the pump sealing 
 BFK-type sealing pumps by the explosion-proof motor, safety clutch, transmission, mixer, operating the clutch, sending pump and base composition 
 2, sealing the pump working principle 
 ① mixing of the slurry 
 When the explosion-proof motor is in operating condition, the variable speed drive through the security activities of the clutch drive mixer blade rotation, makes water-cement ratio required according to the mixer continuously blending the mixture until evenly mixed, stir the slurry to achieve . In the slurry mixing process, the clutch under the control of the operating handle in the disengaged state, sending pump is not running. 
 ② the delivery of slurry 
 Stir in the paste, the operating handle of the clutch in a clutch engagement state, this time, the role of variable speed drive system through the clutch to send pump rotation, sending pump suction in the turning negative pressure in the process of mixing within the mixer inhaled through the connecting pipe slurry delivery pump body, the pressurized output from the pump discharge to complete the delivery of slurry. Pump operation in the delivery process, the mixer has been in rotation working condition. 
 Third, BFK-based technical characteristics of the pump sealing 
 ① sealing the pump working pressure 1.2MPa 
 ② work flow 8-10 l / min 
 ③ working voltage 380V / 660V 
 ④ Motor Model YBK2-100L2-4 
 ⑤ Type Flameproof explosion-proof, explosion-proof mark ExdI 
 ⑥ Sealing the pump motor power 3 Kw 
 ⑦ net volume of 30 L mixer 
 ⑧ sealing pump Dimensions 1450 × 400 × 800 (mm × mm × mm) 
 ⑨ sealing quality of the pump 240 Kg
