H aomei machinery is in he nan province famous concrete pump and other large construction equipment company, as we know, in the construction site, concrete pump can be seen everywhere, here we introduce the under frame structure of concrete pump according to the extension of leg supported pattern mainly divided into the following three types: 1, after scaling before swinging leg structure Before expansion after the characteristics of the swinging leg structure is in the front part of the rotary base connection type telescopic leg, leg connection at the back of the swing type, because this type of chassis structure combines the merits of the former two, reduce weight and has the advantage of narrow construction site, been adopted by more and more manufacturers. Type 2, swaying back and forth leg structure Type back and forth leg underframe structure of form, the leg is open around the base of the rotary hinge point moves to complete, working stability is good, structure simple, but in both sides of the pump truck must leave enough space, is limited by a certain job site. Due to restrictions on the size of the vehicle shape, and the stability of the vehicle work reasons, concrete pump manufacturers at home and abroad are mostly adopt this kind of structure form. 3, type telescopic leg structure before and after Scale before and after the leg leg also calls the XH type, refers to the base of the leg in rotary box within the framework of horizontal extension and retraction, concrete pump of left and right sides of the leg can show X grade separation, can also be parallel scale. Under the influence of pump truck width size, stretch the leg structure size and length is limited by a lot of, for the manufacturing precision of rotary base box frame the demand is higher, the weight of the whole structure and its chassis is relatively heavy, and USES the built-in oil cylinder, disassembling and maintenance difficulties, so in 37 meters above level series has few manufacturers use. Just in the early stages of development of pump truck used by most manufacturers, but because of its operation with more flexible space, now there is still a manufacturer in using this form of structure.
Concrete pump of haomei machinery has been introduced for everyone, but everyone is aware of important parts of the gear pump car "looks"?And use points and characteristics of it?Today we gear pump of pump truck parts is introduced in detail, let us not only learning but also know the why, to let you know more about and easy to use concrete pump. Pump truck parts of the gear pump is installed in the casing of the pair of gears.Sealed space formed by the gear, shell and end cover.When they turn, part of volume increased, oil absorption, another part of the volume gradually decreases, and complete the pressure oil. When gear as shown in the direction of rotation, the right side of the oil absorption cavity teeth gradually separated, the workspace volume increases gradually, the formation of partial vacuum, so the oil in the tank to the outside world under the action of atmospheric pressure and the suction tubing into the oil absorption cavity, into the oil in a sealed between tooth workspace with gears rotate to the left side of the oil cavity pressure, because the left side of the tooth meshing, gathering volume of workspace is reduced, so the teeth taken out of the oil, the oil chamber to the pressure piping.
henan haomei machinery manufacturing co., LTD. Is a collection of concrete pump research and development, manufacturing, sales, leasing and maintenance in a body, a one-stop service of professional enterprise.Concrete pump truck, they are widely used in industrial and chemical fields . we introduce the composition of concrete pump truck parts as follows : 1. The pump body and chassis hopper car. 2. Transport of cement elbow type folding line, is determined by the conveyance height of the folding. 3. The power part of the pump truck, the power part and two branches.Part one is to provide concrete pump works, if use the motor, is about 40 to 60 mw or higher.Second is the need to shore up the fold line part of the hydraulic system energy consumption is small. 4. The operation of the pump truck system and auxiliary small equipment. The above is composed of concrete pump truck parts.
hengzhou haomei machinery is a trustworthy company. Concrete pump in the process of use, must be in strict accordance with the instructions to use, if use undeserved, may cause the following 11 damage: 1, concrete, hydraulic oil splash, cement or other chemicals that cause formulated; 2, due to the hydraulic system maintenance without unloading hydraulic line cause damage; 3, the conveying pipe pressure caused by the open line damage; 4, pumps due to improper lifting or support capsized and cause damage; 5, transfer line, unsecured line sliding or loss and damage or pipe joints, pipe burst damage; 6, pump body parts into the hopper while working or damage caused by sports organizations; 7, high pressure hose burst damage; 8, when slide valve cylinder work, to repair the damage caused by grease system; 9, when the piston movement, the damage caused by hand into the washing room; 10, prevent blender or other rotating parts movement caused by the damage; 11, inside and outside the protection of cables damaged;Electrical component failure and damage caused by pump charged, caused by electric shock damage. Above is the concrete pump improper use may cause damage, hope to be of help. http://concrete-pump-cn.com
H aomei remind you when the concrete pump tube shall be carried out according to its technical parameters and specific situation, here we introduce for everybody four precautions: concrete pump tube A, vertical tube 1. The vertical tube, to reduce concrete pump outlet pressure, appropriate ground horizontal tube length is not less than a quarter of the vertical tube length, usually should not be less than 15 meters.Such as constraints can increase the bend or circular tube meet the demand. 2. When the vertical conveying distance, should be in a concrete pump machine Y tube discharging mouth 3-5 metres of conveying pipe root set pin valve to prevent concrete mixture reflux. Second, the down side tube 1. The down side cloth tube, when the elevation difference is greater than 20 meters, should be in the lower inclined tube set 5 times the length of the elevation difference of horizontal tube;Such as constraints, can increase the bend or annular pipe to meet the requirements of elevation difference length of 5 times. 2. When the slope is greater than 20 째, should first open the discharge valve, stay under the pipeline section concrete with a certain pressure, can close the discharge valve. Third, summer construction Hot season construction, should be cover with a damp cloth and straw bag to cover the conveying pipe, in order to avoid direct sunlight, tube concrete slump loss, transportation difficulties. Fourth, winter construction Cold season construction, appropriate USES heat preservation material in the conveying pipe, prevent concrete seas, and guarantee the concrete into the mold temperature. Above is the concrete pump tube four considerations.
