Mixer operation points and matters needing attention
Mixer, a type of construction machinery, also known as a mixer, is a kind of shaft with a blade rotating in the groove or cylinder, mixing various raw materials into a mixture or a suitable consistency machine. As a mixer, also known as mixer, is a kind of shaft with a blade rotating in the groove or cylinder, mixing all kinds of raw materials into a mixture or a suitable consistency of the machine. Because the mixer in operation and other equipment is somewhat different, so not all people will operate the mixer, if the operation process do not understand the people, blind operation, may lead to serious consequences. Therefore, in the operation of biaxial mixer should pay attention to the following points:
1, start the mixer before the mixing drum operating handle on the “ ” location.
2, after starting, the mixer should be rotated at low speed for about 10 minutes, so that the hydraulic oil temperature rise above 20 degrees can work.
3, in the open-air parking, before the loading, the mixing drum should be reversed, the water and debris discharged, in order to ensure the quality of concrete.
4, in the transport of concrete, to ensure that the sliding bucket placed firmly, prevent loosening caused by swing.
5, in the shipment of mixed concrete, the mixing drum speed is 2-10 rpm.
6, when the concrete is installed in the vehicle, the stop time of the site shall not exceed 1 hours, if the time out should immediately require the on-site responsible person to give timely treatment.
7, transportation of concrete shall not be less than 8cm of collapse, discharged from the concrete into the tank, the temperature is not more than 2 hours to be exhausted, rainy weather when the temperature is low, not more than 2.5 hours.
8, before discharging concrete, the mixing drum should be rotated at 10-12 revolutions per minute for 1 minutes, and then discharged.
9, concrete material is completed, immediately with water hose with the vehicle will feed inlet, a hopper and a discharge chute and other parts clean and wash the platoon to bond in the body around the dirt and residual concrete, and then to the mixing cylinder injection of 150-200L in the water, on the way back to the mixing drum slowly rotating. To clean the wall to avoid residual slag attached to the tube wall and the stirring blade, and again before the water off loading.
10, transportation of concrete, the engine speed at 1000-1400 rpm range, the engine maximum torque, in the transport process of concrete, the speed should not exceed 40km/h, to ensure traffic safety.
11, after the work, should be mixing drum inside and body clean, not to leave the remaining concrete in the cylinder.
12, the mixer in the pump when no idling, continuous use of not more than 15 minutes.
13, to keep the water tank full, for a rainy day, the winter should be shut down, water tank, water pump, water pipes, mixing barrel of water on the net, and parked in Chaoyang, where water, to avoid freezing machine.
14, in winter should be installed insulation sleeve, and use antifreeze to protect the mixer, according to the weather change, replace fuel mark, to ensure the normal use of machinery.
15, when not working, when checking and repairing the hydraulic transmission part of the mixing truck, the engine and the hydraulic pump should be carried out without pressure.
16, in the concrete adjustment gap, stroke, pressure, should be a full-time security staff inspection consent; replacement of parts, must by the minister or manager to sign, otherwise the problem after investigated the responsibility of the relevant personnel.
