Small fine aggregate concrete pump Attention should be paid to draining pumps in cold winter. This article mainly introduces the method and importance of pumping water in winter.
Drainage method: first, open the drain ball valve at the bottom of the tank, then wait for the water in the tank to flow out. Then press the forced drainage button to observe the outlet of the pump outlet. When the water supply no longer flows out of the pump outlet, the operation is completed, indicating that the water in the pump of the pump truck has been completely discharged.
According to the above operation, the water in the pump is discharged during the day, and the pump is not afraid of cracking in winter. Remember, every time you use the pump, you must evacuate the pump. Otherwise, it will be damaged overnight and can not be used in cold winter. It should also be noted that during the forced drainage of pump trucks, the outlet of the pump must be noted.
is often used by many construction machinery. Convenient and efficient structure has won the favor of customers. According to the different architectural characteristics, concrete delivery pumps can be roughly divided into four categories. Today, the editor will briefly introduce the differences between the four categories:
1. mixing pump
The mixing pump also includes a mixed trailer pump and a mixed truck pump. The mixed trailer pump can not walk independently. The mixer pump can walk independently. Compared with other concrete pumps, the mixing pump has agitation function and can be agitated at the scene.
2. sky pump
The aerial work pump with or without agitation device is also called the arm pump. Air pumps are also commonly referred to as small fine concrete pumps. Since it has its own independent support, concrete can be transported without laying pipes. Generally speaking, the operation of small small stone concrete pump is quite flexible and the speed is very fast.
3. vehicle mounted pump
Compared with the skylight pump, the vehicle pump has no independent support. The advantage is that the space occupied is small, so the relative cost is low. Because there is no scaffold, the workers' labor intensity is relatively large. However, compared with the skylight pump, the advantage of the vehicle pump is the low running cost. Therefore, if the high-pressure pipe is used for running, the transmission height will be relatively high.
4. ground pump
Ground pump is also called traction pump. Because there is no car chassis, it can not walk independently, but some tires can be traced to the job site by tractor. Compared with the on-board pump and the on-board pump, the running cost of the ground pump is relatively low, but the drawback is that the conveying speed is slow, and the conveying height is not as good as that of the vehicle pump.
