Terms of Use

Terms of Use

(1) towed concrete pump can use motor vehicle towed the line, but not carrying any cargo, towing speed should not exceed 8km / h; (2) The pressure relief valve concrete pump hydraulic system should meet the specification requirements, the user can not adjust to change; (3) pumps have a construction freeze in the cold season concrete measures; (4) in the hot season, construction, concrete pump to prevent high oil temperature. When the temperature reaches 70 ℃, it should stop the operation or take other measures to cool; (5) pumping concrete completed in a timely manner the hopper, S valve, concrete cylinder, transmission lines clean. After cleaning the pump should accumulator pressure release, cut off the power switch at each stop or off position; (6) Staff members shall climbing or riding on the pipeline, in the high-altitude operations should absolutely be avoided; Ago (7) pumping concrete finished cleaning, new mini mobile concrete batch plant manufacturer to the anti-pump several strokes to reduce the pressure within the duct to avoid an accident; (8) Construction site safety and accident prevention should be set up devices. Such as: instructions and warning signs, fences, metal baffles, etc., must be set in the work area (not less than 1 meter) around the pump, non-operators trespassing without permission. Regular replacement of the transfer line within three meters away from the operator, to be secured with wood or metal separator screen protection; (9) The non-vacuum gauge reading greater than 0.04Mpa job, it may damage the main pump; (10) the electrical control box use, installation, wiring shall professionals; (11) concrete pump hopper concrete must be higher than the agitator shaft, to avoid the intake air caused by concrete splash; (12) the end of the transfer pump pumping operations expenditure leg, received the first rear leg, to round down the branch, and then close the front legs; (13) The operator (of concrete pumps pump station) new mini mobile concrete batch plant for sale should be required to record concrete pumps work. (14) concrete pump before use to effectively fixed, support from four feet off the ground so that the tire, or remove tires. To check the top of the pump hopper and chute support, to ensure stable and reliable. Special attention overturn the pump caused casualties! (15) Note that when pumping concrete splatter or other items into the eye cause eye injury! (16) concrete pump power supply wiring must have leakage protection switch, you should always check whether the electric elements working properly, the cable is damaged, to prevent electric shock casualties! (17) To ensure reliable connection pipelines, regular maintenance, to prevent pipe card, rushed to open clogged pipes burst or cause personal injury! (18) when the hydraulic system is not prohibited unloading opened hydraulic fittings or loosen hydraulic flange bolts, high-pressure hydraulic oil injection can cause a lot of damage! (19) when the pump working, non-hand into the hopper, tank, reversing cylinders and other moving parts of the region, need to check the operation should be shut down!

Precaution

(1) When the installation and design of piping, try to avoid 90. And S-shaped bends. Try not to use a clear pit tubing to reduce a href="http://www.dasionhome.com/products/new-mini-mobile-concrete-batch-plant-china-manufacturer.html">new mini mobile concrete batch plant china manufacturer drag pumping concrete to prevent clogging. You should always check the pump tube, if a direction of the pump tube wear large, timely use of the tube switching position, if the thickness of the thin tubing should be promptly replaced with new pipe to prevent the pump tube during operation off the hook or the replacement pump tube longer caused by the blockade. (2) In order to ensure the continuity of pumping concrete operations, to ensure the quality of concrete pouring, job interval time not too long, to prevent clogging. If for any reason a longer time interval, it should be about once every 20 minutes to start the pump or reverse, forward pump several times, if necessary, to fight the circulation pump to prevent clogging. (3) pumping a pumpable concrete should meet the requirements, if necessary, to determine the mixing ratio by pumping concrete pump test. You should first determine the coarse aggregate than the maximum diameter of the particle size and delivery. Pumping height of 50m or less, not more than 1 for gravel: 3, for not more than pebbles 1: 2.5; when pumping height of 50 to 100m, preferably in 1: 3 to 1: 4 range; pumping height at 100m or more, preferably at between 1: 5: 4 to 1. Flakiness particle content of not more than 10%. 3.3.2 Different pumping height, people can pump concrete slump (Table 1) selection.
