Concrete pump concrete pump pipe inner surface quenching equipment, heat treatment process, concrete pump pipe is made of special material steel tube, through inner surface hardening, infiltration of carbon processing, flange bushings hardness of 58 and 60 degrees, the pipe service life is 3-5 times, the user saves time and cost, removes often in for trouble, improve the production efficiency.No hardening of concrete pump pipe and hardening of concrete pump pipe its performance and life are not the same, after hardening of concrete pump pipe can be transmitted more nearly thousands of cubic meters of concrete.According to the directional button several times, check the pressure of the accumulator value (see numerical value on pump certificate). When the hydraulic oil temperature over 90 ℃, the oil temperature sensor connected, indicator, relay action, power of electromagnetic valve, the pump automatically stops.When the diesel engine oil pressure is lower than 0.04 MPa, indicator, relay...
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.
USES the open hydraulic circuits, distributing valve, the constant power control, automatic compensation gap hydraulic automatic reversing and electric proportion control, the world's advanced technologies such as the concrete aspects of in-depth and meticulous research of the piston automatic lubrication test, won a number of patents, was developed on the basis of comprehensive domestic and foreign latest technology with international leading level of a new generation of products. haomei mechanical drag pump is the domestic specifications of professional production base, can fully meet the different needs of various users.Drag pump completely using assembly line assembly, processing and assembly quality to strictly control each working procedure, each pulling the pump have been simulated condition overload experiment for final inspection, to ensure that the user first boot zero fault, on the basis of quality assurance, concrete pump prices are reasonable, and well received by consumers. http://concrete-pump-cn.com/product_category.php?id=4
