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 action...
Haomei machinery is in henan 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 structureBefore 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 structureType 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 afterScale 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.
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
Concrete pump hydraulic system of fever, directly affects the normal work of the concrete pump, heating phenomenon caused harm, mainly include the following:(1) raise the temperature of working fluid, make work the viscosity of the liquid drops, the leakage of the pump increases, the actual flow of the pump have fallen;(2) hydraulic system and components of seal under the high temperature metamorphic, elastic degeneration ability lower, lower the sealing performance, even seal failure, leakage increase;(3) the work the viscosity of the liquid drop, lower the lubrication performance of the working fluid, the abrasion of hydraulic components, accelerated the wear failure of components, shorten the service life of the components;(4) when the valve core of hydraulic valve, the valve body material, thermal expansion coefficient at the same time, the different between valve core and valve body by thermal expansion valve core is jammed phenomenon, the concrete pump can work.In order to avoid the occurrence of the phenomenon, some concrete pump in use after a certain period of time, had to stop to make the system cooling, which reduces the concrete pump, is analyzed.the influence the construction progress.Fever, therefore, should be aimed at system reason, adopt corresponding measures to control the temperature of the hydraulic system, to ensure the normal use of concrete pump.Haomei machinery company based on solid concrete pump design and manufacturing technology, carry out pump rental business.it Has a strict training of concrete pump operating team and first-class maintenance technology service personnel team, existing HBT60 for leasing, more than 20 HBT80 type concrete pump units, and low taste high stock of spare parts warehouse, to ensure that meet all types of large and medium-sized industrial and public buildings, high-rise residential houses of concrete pumping construction requirements, concrete pump prices will make you more satisfied.http://concrete-pump-cn.com/product_category.php?id=5
