BW250 mud pump is a research and development, production and sales as one of the large enterprises, the current production and operation of the brand has nearly 1,000 species, the main production and operation of coal mine construction equipment. In the machinery marketing industry to create a good product performance, with a strong brand promotion capabilities. Companies in the "quality of survival, to the credibility of development" concept, brought together a large number of elite talent, won a good corporate reputation and reputation.
The products are widely used in mining, geological drilling,coal,railways,highways, water conservancy and hydropower,bridges,high-rise buildings,foundation reinforcement and other projects.
Maximum flow rate
The diameter of the suction pipe
The grouting machine must be mounted on a solid foundation. The parallelism of the prime mover and the grooved pulley shaft and the position of the drive belt must be checked so that they are all in one plane and then tightened with the ground screw. In order to pump to work properly, should be based on the rig site to consider the backwater tank, sedimentation tanks, suction pool and pump the reasonable installation location, BW150 drilling mud pump should be as short as possible suction pipe and suction height. In alpine areas or installation locations where suction sumps are too high, a supplementary inhalation system should be considered.
In the grouting machine should be carried out before the grouting machine system for a comprehensive inspection:
First of all, should carefully check the reciprocating pump power side parts fastening, with the gap, lubrication and so on. Should pay special attention to check the piston compression nut and the crosshead and piston rod connection is tightened; connecting rod bearing, cross head sleeve and slip sleeve with the gap is satisfactory; clutch and variable speed mechanism is flexible and reliable; Crankcase and the clutch device is sufficient oil; hand rotating pulley or motor to see if there is no internal rotation, and adjust the degree of belt tension.
Second, the hydraulic end of the entire circulatory system for careful examination, special attention should be paid to check the bottom of the valve and the water filter inlet hole is blocked by dirt, the bottom valve should be open and close freely close tightly.Hose and water filter at both ends And the suction port connection should ensure that the seal; mud pump well drilling suction valve movement is impeded, the valve seal is good; check whether part of the seal is tightly sealed to prevent leaks leaks and then check the pressure gauge and the buffer device is sensitive and accurate; Turn the valve back to the water position, is discharged into the mud pool; open a suction valve chamber, the suction pipe filled with water.
2, the use of the grouting machine in operation and maintenance
After doing the above work, the clutch handle on the idle position, start the prime mover, check the pump pulley rotation direction to meet the requirements. Closing the clutch with no load on the pump, the operation should be smooth slightly slower. When the pump is running normally, gradually close the back valve in order to smooth the hole would like to transport rinse fluid. When the pump is working properly, for speed control operation must stop the pump, the side of the operation damage to the machine parts.
