HBT, DHBT series of products is the mortar transportation equipment specially developed for the features of floor heating construction, suiting for fine aggregate concrete filled layer during floor heating engineering or the large area and high efficiency construction of mortar filling layer. HBT series products are also suitable for all types of construction projects in the transport of fine stone concrete, refractory, insulation materials transportation, the transportation of green soil in the ecological environment construction and pressure grouting of various foundation piles.
HBT-series fine stone pump have transformed from the original Φ80 delivery tube to Φ100 delivery tube , which can transport the ＜3cm concrete , so HBT-series fine stone pump has more versatile function. (like transport mortar, fine stone and large aggregate concrete).
Electronic control system: high degree of automation and reliability, major appliances adopts Schneider, LS.
Lubrication system: adopting the automatic multi-point lubrication technology featuring one to one lubrication, with better efficiency and the extending service life of wearing parts.
Hydraulic system: The new application of liquid control reversing technology makes pumping more reliable and lower failure rate in the hydraulic system. It can configure the valve specially manufactured for the liquid control system, features with large flow and have lower power and less impact and longer life.
The main oil pump: adopts the constant power variable plunger pump of the joint venture brand, so that the constant power control could effectively prevent motor and diesel overload and could withstand higher pressures and loads than conventional gear pump, so as to ensure the system running smoothly and reliably, the overpressure relief function can effectively protect the main pump and the diesel engine.
Power system: the electric fine stone pump adopts the well-known domestic and foreign brands: Yantai motor, Siemens Beide motor, the fine stone pump of diesel engine adopts low-power high-efficiency Tianjin Lovol, Yuchai.
Hopper device: increased volume, added the fence, equipped with vibration motor , to meet the requirements of fine concrete pumping.
Cooling system: adopts the air-cooled, water-cooled twin cooling system, which not only adjusts to the cold climate, but effectively controls the hydraulic oil temperature so as to ensure the safety and reliability of equipment operation.
Hydraulic pipe fittings: the hose is imported from Italy and the joint is the US Eaton products, the hose connector assembly sets is provided by Eaton, aiming to ensure the safety of the hydraulic system.
S valve: adopts the manganese steel overall casting and the wearing surface adopts wear-resistant materials featuring the dual advantages of pressure and abrasion resistant. Lumen transition is smooth, providing with unimpeded flow of concrete, so that the pumping performance has been further improved.
Glasses plate: the cutting loop was made by cemented carbide with durable service.
Glasses plate cutting loop: glasses plates and cutting loop inlaid adopts the carbide hard to ensure a durable design.
Adopts HBT25-12-33 fine stone concrete pump for transporting mortar. The comparison of mortar and fine stone transported by fine stone concrete pump and mortar and fine stone transported by construction elevator:
As for the same working condition and construction structure, let’s take the ground handling of one site in Qingdao city as an example: both of them have three units with 32 floors and the total area is 32000 m2, the following is the comprehensive comparison between fine stone concrete pumps and construction elevators for conveying.
1.Personnel allocation for fine stone concrete pumps as shown as the following:
One fine stone concrete pump operator, two sets of blenders and two operators for each blender (totally 4 persons), two persons for concrete supplying, two persons for ground cleaning, two persons for concrete pouring, and four persons for smoothing ground, totally 15 persons.
Generally, the average conveying capacity is 12m³/h (the data includes machine shut down time, and the theoretical conveying capacity of fine stone pump is 20m³/h), conveying capacity of every day is 12m³/h*8h=96m³, and construction surface is 5-6cm in thickness, so every day can make 1920㎡, and the average work for each people is 128㎡, which totally needs 17 days for finishing this work.
2.Personnel allocation for construction elevator is shown as the following:
Two persons for two sets of blenders, two persons for concrete supplying, two persons for carrying sand and stone, 8 persons for transportation , two cleaners, four persons for concrete pouring, and two persons for ground smoothing, totally 22 persons. Usually, construction elevator can carry two transporting vehicles at each time, low-rise floor costs 6 minutes and high-rise floor takes 12 minutes for one lifting and each vehicle can carry 0.06m³, so each hour there can be 12 vehicles in 6 times of transporting, if we take 8 people divided into four groups for counting:12 vehicles *0.06*8*4=23m³, so every day can have 460m2 and per capita is 21m2, which needs 70 days for finishing this work.
