1 to improve pumping performance, in the design parameters to reach the level of similar models HBT60 basic configuration for the main pump A7VO160, constant power control, the system pressure 28MPa, the main cylinder bore φ80mm, concrete delivery cylinder φ195mm, travel 1400mm, motor Y250M-4, power 55kW, speed 1480r / min, concrete outlet pressure 4.7MPa, concrete delivery volume calibration 50m3 / h, it can be seen from the pump performance curve of its technical performance parameters are lower, the configuration for proper improvement, the technical performance parameters improved significantly, that is the main pump A8VO107 double pump, Constant power control, system pressure 28MPa, main cylinder bore φ100mm, concrete delivery cylinder φ195mm, stroke 1400mm, motor Y280S-4, power speed 1480r / min, 75kW, concrete outlet pressure of 7.36MPa, concrete delivery capacity of 65m3 / h, the model changes to HBT60G. Pump performance curves for HBT60 and HBT60G are as follows: Performance analysis is as follows: (1) In theory, the HBT60 concrete pump enters the constant power at the outlet pressure of about 1.5MPa, but the actual system itself has pressure loss, the power will enter the constant power, with the delivery distance and height increases, the delivery volume continues to decline; due to increased power, HBT60G concrete pump enters the constant power at the outlet pressure of 2.5MPa or so, the theoretical delivery of concrete reaches 62m3 / h, compared with the HBT60 concrete pump at 2.5MPa when the side volume 45m3 / h, an increase of 17m3 / h. (2) The maximum outlet pressure of HBT60 concrete pump is 4.7MPa, the concrete theoretical delivery volume is 25m3 / h, the maximum outlet pressure of HBT60G is 7.36MPa and the theoretical delivery volume of concrete reaches 25m3 / h. The delivery volume of 37m3 / h, indicating that the pumping distance or height of HBT60G concrete pump is nearly twice that of HBT60 concrete pump. (3) When pumping the same distance or height, the hydraulic system pressure HBT60G concrete pump is smaller than the HBT60 concrete pump, the system reliability is high. For example, when the outlet pressure is 3MPa, the pressure of the HBT60G concrete pump system is 11.5MPa, and the HBT60 concrete pump The system pressure is 18MPa. 2 configuration and structure changes, improve the reliability of the machine In order to improve the reliability of the whole machine, great improvements have been made in the hydraulic system and other types of structures (1) to improve the hydraulic system, the gear pump to the mixing and cleaning system is replaced by a double gear pump to make mixing and cleaning into independent circuits, and to increase the stirring system pressure and washing pressure to reduce the pressure of the main system, Improve the life of hydraulic components, improve the cleaning capacity of concrete pumps. (2) to improve the mixing drive system, the chain of transmission to the motor and drive shaft directly connected to the form, to simplify the structure and reduce the point of failure. (3) Improve the slide valve cylinder assembly, additional buffer system and piston guide sleeve in the cylinder to improve the service life of the spool valve cylinder. (4) Increase the protection system on the electrical system, make the electrical control more reasonable, and ensure the stability of the operation. The safety has also been greatly improved. In short, after the improvement of the concrete pump, its comprehensive performance has been greatly improved and achieved the expected purpose. It reflects well in actual use and has obvious effect. It has a qualitative improvement compared with the previous ones and meets the needs of construction and production.

Technical Measures to Improve HBT60 Concrete Pump
The early purchase of our company HBT60 gate valve concrete pump power is low, the outlet pressure is low, the structural design is backward, coupled with the long service life, serious wear and tear of the transmission cylinder, hydraulic system leakage and other issues, the efficiency is very low, even replace the worn Components, because of its low technical performance parameters, can not meet the current construction requirements. Therefore, it is necessary to improve the pump performance parameters on the basis of the original, to improve its unreasonable structure, so that it is upgraded to HBT60G.
