Operating system and the performance of concrete pump
Control concrete pump electrical control system there are five mechanical, hydraulic, electro-mechanical electrical control type, the programmable controller type, logic-controlled. In addition to installing the concrete pump electrical control system to complete the control tasks, manual control is also equipped with the operating system, it is also part of the system of control. If mechanical manipulation, generally bar system controls and flexible shaft steering mechanism in two ways. If you compare the two is not difficult to find, flexible shaft control mechanism have more advantages, such as layout flexibility, Mobile Concrete Batching Plant Manufacturers high transmission efficiency, transition joints and small air travel less convenient travel regulation, so concrete pump control system The main shaft is to select the operating mechanism. According to actual needs, in trucks operating system should be able to achieve variable speed operation, and enables the joystick to stop at any position locking mechanism is operated stepless critical devices, generally you can use the disc springs or spring board. For ease of operation, joystick are designed to be installed at a convenient location, such as Putzmeister BSF36.09Z type pump, which controls the engine speed joystick mounted on the side of the ladder, the operation is very convenient. Concrete pump control system is mainly used to control the main pump flow and engine speed, thereby changing the concrete pump truck emissions. Such as the use of hydraulic control, it can get power directly from the hydraulic drive pump pumping systems, and to achieve through manual hydraulic control valve. There is a close relationship with the properties of concrete, while paying attention to the details of the rules in the course of operation, the timely detection and timely troubleshooting to improve pump efficiency. There are two methods to clean water pipes and gas wash. Whether water or air wash, should the valve housing and hopper clean. When washing, the water soaked cement bags and tied into a cylindrical cleaning ball has been put into clean cone tube, connected to the cone, pipe, close the discharge door, hopper filled with water again (to be kept Water constantly). Pumping water until cleaning ball out from the tip of the delivery tube so far. Gas wash or compressed air purging, is the first water-soaked cleaning ball into the air purge fitting, connect the first phase with adjustable pipe root straight, and at the end of the pipe connected to the safety cover, safety cover opening to down. Control air pressure does not exceed 0.8MPa, slowly open the valve when the concrete can flow smoothly before opening the air valve.
Concrete mixer cleaning process
Since the concrete in a short time solidified into a lump, and the steel and the paint has some corrosion, so concrete tank after each use, wash tank attached to the concrete and the concrete is expected out daily maintenance must carried out serious work. Including: a. Rinse with water before each charging inlet, the feed port remains wet when charging; b. While in charge of the vehicle carrying the clean water tank filled with water; c. After loading washing feed, wash near the inlet remaining concrete; d. To the site after discharge, Construction Equipment Manual Concrete Placing Boomfor sale wash out the tank, then into the concrete wash water tank plus 3 concrete mixer 0-40L; maintaining a positive concrete tank when the vehicle is turned slowly return; e. Remember to let go before the next charging concrete sewage in the tank; f. Thoroughly cleaning the surrounding concrete finishing work each day and expected out of the tank, to ensure that non-stick cement and concrete caking. These work as long as one does not seriously, it will bring a lot of trouble for future work.
