(6) For the mixer to be excavated with the hopper pit, the bottom of the pit should be tamped, and the bottom end of the loading rail frame should also be tamped or the back of the paving frame should be supported by wood to prevent long working time. Deformation (7) The mixer should be equipped with a rainproof shed, no muddy water around the machinery, clean and tidy, and all kinds of cards are complete; (8) The mixer should be equipped with “one machine, one brake, one leak and one boxâ€. The leakage protector parameter is 30M A×0.1S, the motor insulation resistance value should be greater than 0.5MΩ; the protection zero line should be no less than two, the console instrument, indication The signal is accurate and reliable; Installation and acceptance of the double-shaft concrete mixer mortar mixer is: (1) The installation is stable and firm, the walking wheel should leave the ground, and the machine base should be higher than the ground to facilitate discharging; (2) The transmission part, working device and protective device should be firm and reliable, flexible and complete; (3) A safety iron gate must be installed at the inlet, which cannot be removed at will; (4) The mixer should be equipped with a rainproof shed, no debris around it, neat and tidy, and the operation rules are complete; (5) The mixer should be equipped with “one machine, one brake, one leak and one boxâ€. The leakage protector parameter is 30M A×0.1S, the motor insulation resistance value should be greater than 0.5MΩ, and the zero line should be no less than two. Concrete pumping The equipment installation acceptance content is: (1) The placement of the pumping equipment should be kept at a certain distance from the edge of the foundation pit. The pump should be placed in a stable and reliable manner, and there is no obstacle in the action range of the boom; (2) The concrete pump tube support should be fastened and reliable, the joint is sealed reliably, and the “Y†type pipeline should be connected with the cone type pipe; (3) The joint bolts of each part of the concrete pump pipe must be fastened; (4) It is forbidden to directly attach the vertical pipe to the output port of the pump. The horizontal pipe of not less than 10M should be installed in front of the vertical pipe, and the check valve should be installed near the pump of the horizontal pipe; (5) When laying down the inclined pipe, the lower end should be connected with a horizontal pipe, the length of which is at least 5 times of the height difference, otherwise the bending pipe should be used to increase the resistance; (6) When the pumping system is under pressure, do not open any conveying pipe and hydraulic pipe. The safety valve of the hydraulic system shall not be adjusted arbitrarily, and the accumulator can only be filled with nitrogen; (7) The parking brake and locking brake of the pumping equipment should be used at the same time. The tire should be tightly wedged, the water supply should be normal and the water tank should be filled with water. There should be no debris in the hopper, and the lubrication points should be properly lubricated. (8) All parts of the operation switch, adjustment handle, hand wheel, control rod, cock, etc. should be in the correct position, the hydraulic system should be normal without leakage. 1, no protection to zero, no leakage protector, each deduction 5 points 2, clutch, brake, wire rope can not meet the requirements, each button 3 points per shift before the mixer should be checked and commissioned, the main contents of the inspection are: clutches, brakes should be flexible and reliable, wire rope broken, wear should be replaced, wire rope clamp The connecting parts such as heads and bolts should be free of loose gearbox without abnormal noise, no oil leakage, the running parts of the supporting wheel and other parts are normal, and the upper and lower limits of the hopper are sensitive and reliable. After the inspection is completed, the empty car test operation is normal, then it can work. .
Disposable surgical blade is the most popular blade shape ideal for making short and precise incisions. It is utilised in a variety of surgical procedures including the excision of a skin lesion or recurrent sebaceous cyst and for opening coronary arteries.Disposable surgical braided sutures is a nonabsorbable sterile surgical suture composed of an organic protein called fibroin. This protein is derived from filaments of silk fibroin. We also supply hypodermic syringe
Applications:1) Disposable surgical braided sutures indicated for use in general soft tissue approximation and/or ligation, including use in cardiovasular, ophthalmic and neurological procedures.2)It elicits a minimal acute inflammatory reaction in tissues, which is followed by gradual encapsulation of the suture by fibrous connective tissues. While SILK SUTURE is not absorbed, progressive degradation of the protcinaccous silk fiber in vivo may result in gradual loss of all of the suture's tensile strength within one year.3)It is available in size 7/0 to 4 (U.S.P.) and supplied as needled suture and ligature. And supplied as needled suture and ligature.4) Also it is sterilized
