Roadway reinforcement bw600 / 10 grouting machine supplier ground exploration mud pump

Hydraulic end of basic structure of bw250 mud pump The hydraulic end is composed of oil pump head body, cylinder liner, piston, piston rod suction valve and discharge valve
Its function is to form the change of liquid cylinder cavity through the reciprocating motion of piston in cylinder liner, complete energy conversion and realize the suction and discharge of liquid The pump crankcase is composed of two pole gear speed change mechanism and crank connecting rod mechanism
The input shaft and output shaft of the crankcase are butted and driven through the jaw coupling
When the double speed change gears on the input shaft of the crankcase mesh with the corresponding gears on the crankshaft respectively, the crankshaft can obtain two-stage speed
Plus the speed of the transmission
A total of 8 speeds can be obtained on the crankshaft to realize 8 speed changes
The hydraulic end belongs to the straight through structure, which is easy to manufacture and has high assembly precision Type: horizontal three cylinder reciprocating single acting piston pump Stroke: (mm) 70 Cylinder diameter: (mm) ￠ 70 Pump speed (R / min) 222; 130 ; 86 ; 57; 183 ; 107; 71 ; 47  Flow (L / min) 150; 90 ; 58 ; 38; 125; 72 ; 47 ; 32  Pressure (MPA) , 1

5kw Overall dimension (mm) 1840mmx795mmx995mm mass (kg) 560 Purpose of bw250 mud pump: , In construction engineering, it is used to transport mortar vertically and horizontally In the metallurgical steel sector, it is used to repair blast furnaces and other equipment Bw250 mud pump plays an important role in the drilling construction process
Once the 250 mud pump fails, it will cause huge losses to the whole drilling construction, but the occurrence of mud pump failure cannot be realized
Therefore, it is important to maintain the mud pump well: 1
The oil quantity and quality of lubricating oil shall be kept clean
Part of the oil bottom shall be drained and some new oil shall be added every month, and the oil can be changed every six months 2
The bearing assembly is clean and free of dust
Check the temperature change of each part of the bearing and whether there is abnormal noise
If the temperature is too high, the bearing will be burned
3
Check the working condition of piston and cylinder liner frequently to replace the piston in time
Check the service condition of the valve cover and cylinder head sealing ring, the wear and erosion of the valve seat, valve body and valve rubber, which can be replaced in time, and check whether the operation of the mud shale shaker, desilter, desander and sand pump is normal
4
Check the piston and pin of the valve and replace the safety pin of the valve assembled on the driving shaft in time to ensure that the mud pump can operate under drilling conditions
5
The mud pump needs to be disassembled and inspected every two years to detect the clearance of the bearing, maintain and repair or replace it directly
The mud pump should also be coiled regularly in order to prolong the service life of the mud pump
