Mortar pump work should note the following: 1 at any time in the mortar bucket mortar stirring to prevent precipitation. 2. Note that the pressure gauge. When the pressure exceeds the limit, you should turn off the power of large and small self-propelled rotary jet pile, until the pressure is reduced after the start, to avoid excessive pressure caused the hose to burst. The motor should be installed reliable ground to prevent electric shock. Guard on mortar pump are not free to remove. 4. Always check the gearbox lubricant oil at the end found dirty, promptly replaced with new oil. 5. The use of the process, found fault Churning Pile, prohibited live maintenance, to prevent accidental injury. Dual fluid injection pump main technical characteristics 1, single-cylinder double-acting, reciprocating piston rotary jet pile excavation, enabling the two liquids suction. 2, hydraulic drive track-type rotary jet pile driver, the machine is reliable, high pumping pressure 3, the original commutation mechanism, there are special requirements of the workplace (Ex) can also be applied 4, compact, suitable for small spaces Construction
