Concrete delivery pumps are widely used in practice. Saintyol DAWIN Machinery believes that the operation details of small concrete delivery pumps mainly include the following points based on years of production and research experience:
First of all, the hopper net of the small concrete pump should not be full of concrete, and the super-sized aggregates and sundries on the net should be removed in time. When the stirring shaft in the hopper is stuck and does not rotate, the pumping should be suspended and Reverse the operation in time to troubleshoot. The concrete in the hopper should not be too small to prevent pipeline blockage due to suction. When the supply cannot keep up, stop pumping in time.
Second, when the pumping operation needs to be interrupted for a long time, the mixing work in the hopper should be stopped, otherwise the coarse aggregate in the concrete will sink, and when pumping again, it should be stirred first, and it must be carried out twice in the forward and reverse pumping operations. Normal pumping can only be resumed after a stroke.
Also, when starting the drum-type mixing pump for dry running, if the temperature is low, the dry running time should be longer, and the temperature of the hydraulic oil must rise to 15 degrees Celsius to pump. Add a certain amount of clean water to the hopper to moisten the hopper, distribution valve and delivery pipeline.
In addition, before using the concrete delivery pump, 0.5 to 1 cubic meter of mortar must be pumped first, and part of the mortar must be kept in the hopper (to the upper and lower parts of the hopper axis), and pumped together after the concrete is added to the hopper.
Fifth, in the process of pumping concrete, strict attention should be paid to the actual mixing quality and slump of the concrete. If the mixed concrete does not meet the pumping requirements, it must be rejected. Concrete pumps have different requirements for high and low temperature pumping concrete, and need to be operated differently.
Finally, during the pumping process, always observe the pressure and lubrication of the various instruments on the pump machine. If the pressure gauge of the concrete delivery pump is abnormal, it should be eliminated in time to ensure the normal pumping.
Concrete delivery pumps and mixer pumps are the main products of Qingdao Saintyol DAWIN Machinery. Small concrete delivery pumps are mortar delivery equipment specially developed for the characteristics of floor heating construction. They are suitable for large concrete filling layers or mortar filling layers in floor heating projects. area, high-efficiency construction. The full hydraulic control reversing hydraulic system eliminates the four easily damaged components in the electronic control reversing system, reducing the maintenance cost of the equipment.
Qingdao Saintyol DAWIN Machinery Co., Ltd. is a large-scale construction machinery and equipment enterprise integrating scientific research, production, sales and after-sales service. The product performance is reliable, and it is favored by the majority of colleagues in the construction industry. Its mixing pumps and small concrete delivery pumps cater to the new rural areas. The construction has greatly solved the problem of narrow roads in rural areas and difficulties for vehicles to pass.
