Q:What do these types of concrete pumps mean?
Concrete conveying pump HBT80-18-16: according to the national standard "GB/T13333-2004_ concrete pump"
Q:How to choose concrete pump?
A concrete pump motor power is a prerequisite for determining the export pressure and transport volume, the motor power is certain, will increase pressure to reduce the amount of transportation; on the contrary, reduce export pressure, will make the delivery volume increase
Q:What is the farthest pumping distance of concrete pump truck?
Ground pump or air pump, the current delivery distance of the pump is 56, the ground pump can transport 300 meters
Q:What are the functions of concrete pump truck?
According to the structure and use of divided into drag type concrete pump, truck pump and pump car, according to the power type is divided into electric concrete pump and diesel power concrete pump
Q:How much is the pump for a month?
Remove the pump car monthly fuel maintenance consumption (about 10 thousand to 5000), calculate the monthly one of the clay, probably earn about 14 to 150 thousand net!
Q:What are the causes of pipe blockage in concrete pump?
When the fine sand content through the 0.315mm screen is small, even if other concrete technical specifications meet the requirements, it will plug the pipe. Because these fine sand plays a similar role in the concrete, it can reduce the friction between the tube wall and concrete, improve the fluidity, increase the cohesion and water retention, and greatly affect the concrete pumping performance
Q:What are the types, classifications and specifications of concrete pump?
According to the maximum hourly transport rate, there are 20-100m3 range, and most of the concrete pump can achieve two variable displacement or stepless variable
Q:How to diagnose the blockage in the inlet of concrete pump?
The feed port is blocked and the pump operation and hydraulic system are normal, with no abnormal sound and vibration. The hopper has larger aggregate or agglomerates and is stuck or arched at the feed port
Q:What is the second generation pumping technology of concrete pump?
Concrete pump, S pipe distribution without PLC electrical components to participate in, the failure rate is lower, more reliable control, product life has greatly improved
Q:What are the skills of concrete pump?
In the process of pumping concrete, with the increase of pump pressure, pump impact force will force the tube to move back and forth, this is not only the loss of pumping pressure, and connecting parts between the pump in shock and intermittent tension state, can lead to premature damage, and rubber pipe cement slurry overflow, therefore must be fixed the pump
