Haomei used concrete mixer hydraulic drive system requirements

Haomei machinery used concrete mixer hydraulic drive system requirements
1, a new car before use, first of all, check for and remove all parts of the hydraulic system of dust and debris, and check all connections are correct and there are no other problems.
2, Mobil Oil tank mount DTE26 hydraulic oil (oil tick over, also block the pump casing and motor oil.
3, start the engine, control servo handles the mixing Drum turn at low speed is observed hydraulic system is working properly.
4, the oil temperature must not exceed 60 ° c, the truck-mounted concrete pump pressure must be less than 0.25MPa.
5, the attention of the fan on the radiator is within the range of 50 ° C-70 ° c operation. Fan failure when not in operation should be repaired in a timely manner.

6, fill the pump relief valve pressure relief valve, high pressure relief valve pressure is factory-set and shall not be arbitrarily changed.
7, circuit components and piping there shall be no leakage, such as leakage, should be repaired in a timely manner.
8, work status, not free to repair and adjustment.
9. hydraulic pumps, motors, if fails, needs to be replaced to send specified professional maintenance department repairs, dismantling the old pump, motor, put a new fuel pump, motor should pay attention to the following points:
1) remove the old pump, motor, you should remove tubing, demands that the oil pump and tubing on the interface immediately sealed to prevent dust from entering the pump and pipe, and then under the pump removed from the js500 concrete mixer.
2) stable and equipped with pumps, motors. Note: the screws tight, seal pumps, motors, oil, took over.
3) all tubing after installation is completed, turn down the oil pump r plug, drain pump in the air until the r does not contain gas from the oil, and then tighten the r oil plug.
4) remove the motor from the uppermost t port connection, Madanes joined clean hydraulic fluid until full, then tighten the fittings.
5) check oil level, if not to the level above in the middle position, adding clean hydraulic oil in place.
6) start engine and idle speed idle for 10 minutes (control box two lever in the neutral position, mixing Drum doesn't move), and check the oil pump, motor noise, and the tubing if there is leakage.
7) slow handling, mixing drum in one direction at a slower feed direction 20 minutes (no material in the mixing tube, under the car at idle);
8) the joystick back to middle position causes the drum to stop and check that the oil level, fuel to.
10. hydraulic oil usage Description:
(1) for new vehicles and mixing barrel must be cleaned after the first one accumulated 300 hours of cooling and replace the filter and hydraulic oil.
(2) after every six months or after 500 hours replace the filter and hydraulic oil.
(3) the hydraulic oil must be high quality imported or domestic hydraulic oil, and after a 10 micron filter precision can join the tank. MOBIL is recommended (Mei Foo) DTE26,SHELL (shell) TELLUS68, BP (United Kingdom oil) SHF68,CASTROL AWH68 or the same grade hydraulic oil, 68th, is not available with other oils instead.
(4) do not mix different brands of hydraulic oil, and replace the hydraulic oil must be placed inside the tank of the hydraulic oil after the new hydraulic oil can be added.
(5) the hydraulic oil viscosity:
At ambient temperatures below 15 ° c should be with the lower viscosity oil, you should use the MOBIL (Mei Foo) DTE15,SHELL (shell) TELLUS46,BP (United Kingdom oil) SHF46,CASTROL AWH46 oil or equivalent.
Mixer trucks parked overnight, even if the climate is warm, the oil temperature will decrease, so, in a relatively warm climate allows the engine to idle for five minutes at the start, colder climates to operate only after idling for ten minutes.

The methods of using concrete mixing plant

The belt type concrete batching plant on power up and power off is a necessary process. The reasonable and safe operating concrete mixing plant not only can reduce the accident, but also can ensure the service life of the concrete mixing plant. So the station master should plan for the work flow which the operator can operate the concrete mixing plant safely so as to ensure the smooth production. Today I will do a brief analysis for the people, so that we can use it correctly.

The methods of using wet mix concrete batch plant

The sequence of starting wet mix concrete batch plant:
Firstly, the control switch which includes the main engine, the cement silo, the pump, the mixing chamber, the flat belt, the inclined belt, and the discharge switch in the motor cabinet should be opened. Then it should open the computer host. After opening, firstly it should test the mechanical movement capacity. The first is to operate the diagonal belt, and then run the host, and finally to run flat belt. It can guarantee that the inside scrap can work out and maintain the mechanical integral movement. If in the case of normal operation, you can open the truck-mounted concrete pump, batching machine and so on. Thus the machine began to work properly. If the starting sequence of some of the equipment is not right, it also means that there is no normal start. It will cause damage to the device for long time, this situation is to resolutely put an end.
The sequence of closing concrete mixing plant:
Closing ingredients (including aggregate, cement) switch, water switch, feeding switch(belt without stock), mixing console switch(there is no aggregate in the concrete mixer tank ), discharging belt switch(there is no aggregate on belt), storage bin door closed, cleaning the mixing tank, closing water valve switch and general supply.
The above are steps to start and close the concrete mixing plant. So the users should seriously treat the concrete mixing plant.

The little secret of concrete mixing plant

Concrete mixing plant consists of concrete mixer (JS series), concrete batching machine (PLD series), cement silo (bulk cement silo or flake cement silo), screw conveyor (LSY series), control system (centralized control system or automatic control system). Each device has its own secret, we'll introduce some of the secrets of concrete mixing plant in the following.

The little secret of China concrete mixing plant

The mobile concrete batching plant is operated by the control system. The control system of HZS series of concrete mixing plant adopts advanced control system and reliable performance and has the function of printing and air conditioning, which is easy to operate. So we should be sure to pay attention to the daily inspection work of the control system, once found abnormal control system, we need to ask the special staff to maintain. The host of the concrete mixing plant adopts JS series twin shaft forced concrete mixer. This mixer is applicable to be used in the mixing of plastic, rigid and lightweight aggregate, concrete and mortar, which is widely used. But JS series concrete mixer can’t be used alone, when using it, it need to configure the PLD series of concrete batching machine to make production more efficient.
Concrete batching machine is the essential equipment in the concrete mixing plant. The PLD series concrete batching machine adopts the smallest batching control instrument in the world, which has accurate and stable ingredients, advanced calculation method and effective control error. It is a kind of advanced dispensing equipment and effectively guarantee the quality of concrete production.
Whatever which kind of the containerized concrete batching plant it is, it cannot do without the cement silo, the use of cement silo is also very simple. But due to its large reserves of cement silo, the bearing capacity of cement silo’s leg is also large, so the protection of the cement silo’s legs is very important.
The more comprehensive to understand the concrete mixing plant, the more convenient and safe to use it, so we can not miss these secrets of the concrete mixing plant.
