Coal seam injection pump 
 Coal injection pump the 2BZ seam injection pump pulse injection pump mine water injection pump 
 Product Overview: 
 Type 2BZ-40/12 pulse seam injection pump for various types of coal seam water injection, especially hard water injection coal seam injection: the most effective techniques to solve the low-permeability, high hardness hard water injection coal injection, China is currently used in the practice of coal seam water injection pulse seam high-pressure injection pump. 
 This product is what works? 
 Coal injection pump pulse pump, regulator and pressure monitor with a throttling device. 
 The pulse pump output pressure, pulse high-pressure water from the OP, with the throttling device pressure regulator control and to ensure that the pulse pressure at the set pulse water pressure P, the control output pulse flow of water injection seam penetration ability automatically adjust the pressure monitor intermittent display the size of the pulse water pressure. 
 Product advantages: 
 A pulsed pump fluid end brass matrix, with good corrosion resistance, left foot a good meet coal mine corrosive water use requirements; 
 (2) injection pressure, injection flow pulse, adjust the maximum injection strength (pressure), water flow, the pulse intensity (pressure) automatically adjust based on the infiltration capacity of the coal seam, the pulse intensity reduced water infiltration capacity, with coal seams increased pulse frequency remain unchanged, the pulse of water is forced to communicate seam original closed within the cracks and the formation of new fissures net; 
 Three pulse seam injection pump in the use of pulsed high-pressure water injection is mandatory to communicate the original seam internal closure of cracks formed in the coal seam internal fissures network, static pressure injection infiltration of coal composite injection in the cessation of pulsed high-pressure injection system automatically converted to static pressure injection; 2BZ-4012 pulse seam injection pump commonly used sets of supplier. Sets the pulse seam injection pump including: 2BZ-40/12 pulse seam water injection pump, injection manifold block, high pressure water meter, water supply, automatic control water tank and sealing pump.

 The detailed work details are as follows: 
 Pulse seam injection process as follows: motor drive pulse seam injection pump operation, the output pulse high-pressure water into the pressure regulator with a throttling device, pressure regulator according to the ability to penetrate the coal seam in the premise to ensure sufficient pulse pressure strength under automatic control output size of the water, the pulse intensity is displayed by a pressure monitor; high-pressure water through the piping system was highly pulse injected into coal seams within the process, without fracturing the coal seam conditions, the pulsed high-pressure water in the coal seam internal formation of water hammer phenomenon, forcing the original closed seam internal fissure to communicate with each other or directly to the formation of new fissures network, provision of water in coal seam internal network channel flow, static pressure water penetration into the coal seam through these networks internal, so that the seam to get effective moist coal seam inject the amount of water from a high voltage meter display. General conditions under pulsed high-pressure injection pulse pump fracturing and communication seam cracks, hydrostatic water infiltration seam dynamic, static pressure alternating water injection (water wet and into the coal seam tiny cracks is the capillary force and the molecular movement, and the injection pressure. injection pressure is only to force the water into the coal seams within the fracture network); pulse pump open for some time (the length of time as the coal seam development and communication of the original fissure, about half an hour generally open the pulse pump pulse pump tested once pulse pressure, pulse pressure decreased significantly, pulse pressure water is forced to communicate in a considerable extent of the coal seams of the original fissure network or in a certain range within the coal seam formation, new fissures net), turn off the pulse pump for static pressure water injection, the pulse seam injection pump static pressure water injection flow was significantly reduced or injection of water is not turned on again, and so forth until the end of the seam water injection work Tel: 18766872840 18660761596
