The regular and correct maintenance of the pump parts is necessary to ensure the efficiency, reliability and working life of the pump. Because the pump working environment is very bad, the unit of work by the Dongying Tianyuan Machinery Factory for different pump, and stressed the key:
One, the daily inspection of the pump car
In order to ensure the normal operation of the equipment, without error of construction, the operator is required to inspect and maintain diligently in the construction before and during the construction.
(1) check hydraulic oil oil level, oil quality should be light yellow transparent, no emulsification or turbidity, otherwise it must be replaced.
(2) fill the grease, connect the water tank and the spare water tank to fill the water.
(3) check the wear of the cutting ring and the eyeglass, if the wear is serious, it must be replaced immediately. The inspection of concrete should be sealed well and no mortar penetrated into the water tank.
(4) check the working condition of the lubrication system. We should see progressive movements of the indicator bar of the progressive distributor, and the location of the S pipe swing arm bearing and the position of the mixing shaft bearing have lubricating oil spills.
(5) check the indicator of the vacuum table on the oil suction filter of the main oil pump and should be in the green area (the vacuum meter indicates no more than 0.035Mpa).
(6) check whether the hydraulic system has oil leakage and oil seepage.
(7) check the wear degree of concrete pipe by knocking and check whether the pipe joints are well sealed
Two. Maintenance of the part of the chassis
(1) after replacing the engine oil for 50 hours, the engine should be changed. At the same time, oil filter and diesel fine filter should be changed, and diesel coarse filter and air cleaner should be cleaned. Change every 250 hours later. When the oil level is not enough to be added, the same grade and type of oil must be used in accordance with the requirements.
(2) when the pump works, every 10 hours or every day, check the oil level, if the amount of oil should be injected in time;
(3) force the use of 200 hours in the transfer case gear oil pump should be replaced, then every oil change according to 1000 hour intervals (or half) is a force taking gear box bearing in butter, every 1000 hours with a;
Three, the maintenance of the pump part
(1) the oil and oil level of the hydraulic oil is checked every 8 hours during pump operation. If necessary, it is replenish and replace. The new hydraulic oil must be consistent with the oil number in the fuel tank. The hydraulic oil filled with the pump is Esso H46. Normally pump 20000 cubic concrete or replace one oil once in half a year. Oil tank must be cleaned when changing oil, and oil tank of each part should be discharged.
(2) the oil pump work check every 8 hours of lubricating oil, recommend the use of 00# non extreme pressure grease in semi fluid pump, concrete cylinder is connected with the water tank, the S tube size bearing seat and stirring end seat should oil overflow;
(3) the pump should adjust the gap between the eyeglass plate and the cutting ring after pumping 3000 parties, such as the serious wear and tear should be replaced immediately. The inspection of concrete should be sealed well and no mortar penetrated into the water tank.
(4) after 500 hours of use, the pump should check the wear condition of the S tube and the S tube bearing position, and replace the shaft sleeve and the cone sleeve when necessary.
(5) check the vacuum table indicator of the oil suction filter of the pump, if the position of the vacuum table pointer reaches the red area (or more than 0.04Mpa), the filter core must be replaced.
(6) the system must be checked to check whether the pressure of the system is normal or not to check the leakage of the hydraulic system.
Four. Maintenance of the upper arm of the arm
(1) the gear oil in the rotary reducer of the turntable must be replaced after being used for 100 hours for the first time. After that, every subsequent oil change shall be carried out at intervals of 1000 hours (or half a year). The recommended brand is Nanhai 85W-90 heavy duty gear oil with a total volume of 8 liters.
(2) arms, legs, each joint ring gear rotary bearings and rotary gear lubrication gear shaft end of the choke should be every 60 hours of work for inspection and oiling, lubricating oil used for 3# calcium grease;
(3) in order to reduce the risk of pumping concrete and fault, must use the correct diameter and the thickness of the pipe, the right clamp and safety lock.
(4) in order to make the wear even and prolong the service life of the pipe, it can regularly rotate the conveying pipe: each casting is about 5000 square, the straight pipe rotates 120 degrees clockwise, and the elbow turns 180 degrees.
(5) when the pump truck works for a period of time, we should carefully check the welds around the turntable, boom and outrigger. If there is any weld cracking, we should contact with our company immediately and handle it properly.
(6) after the completion of the pump concrete work, the whole pump car should be cleaned and the residual concrete in the pipe is strictly forbidden.
(7) special warning: in order to ensure the safety of the equipment, the front end of the pump is only allowed to receive 4 meters of hose, and no other pipes are allowed.
The above is about the correct maintenance of the method of pump accessories, I hope to help you.
