For more details about KCB stainless steel gear pump, please visit: Construction Hoist Safety Device
Safety is one of the most important for Construction Hoist, thus the Construction Hoist Safety Device is required. SAJ safety device is a product of BQ. When a cage over-speeds the device should act cut off the power stop the cage on mast gradually. The safety device is adjusted and sealed. Do not disassemble it. The using time limit of safety device are signed on it`s nameplate. Safety device must be delivered to the factory and inspected after it reached to time limit.
Safety device board is the connected part between safety device and other structures, it can take the impact of stopping the cage. There are installed lower speed switch, upper travel limit switch and final limit switch, once the switchs touch the relevant cam the cage will act.
We also supply other spare parts for construction hoist, such as construction hoist Mast Section, Construction Hoist Anchorage Frame, Passenger Hoist Cage, Construction Hoist Overload Protector, Sliding Contact Line, Construction Hoist Motor, Construction Hoist Reducer and so on.

1. Attention should be paid to the removal of KCB stainless steel gear pump:
1 Before disassembling, fully understand the structure and characteristics of disassembled parts and prevent them from being disassembled and damaged.
2 Disassemble and place in a reasonable order, especially multi-cylinder KCB type stainless steel gear pump. After the parts are dismantled and cleaned, KCB special pumps should be placed in a clean place in the order of the cylinders, and the numbers should be seated. Parts of each cylinder cannot be mixed.
3 Grasp the appropriate degree of dismantling, the demolition on the demolition, should not be demolished, do not disassemble.
4 Select the proper disassembly tool and do not disassemble it brutally.
5 Disassembly Prepare for future assembly.
2, KCB stainless steel gear pump assembly should pay attention to matters:
1 Piston rods are grouped by size. Pistons and cylinder liners, pistons and piston rings, piston pins and pin holes, connecting rods and bearing bushes, etc. shall be selected according to the size to ensure the technical requirements for cooperation.
2 The weight requirements of the piston connecting rod set. Multi-cylinder KCB stainless steel gear pumps have certain requirements for the weight of pistons, connecting rods, and piston connecting rods of the same model, and there are grouping marks. For example, the weight difference of the four pistons of the 495KCB type stainless steel gear pump is not greater than 8 grams. The weight difference of the four connecting rods of the same group is not more than 10 grams, and the weight difference of the piston connecting rod group is not more than 30 grams. In the assembly, the repairman shall install according to the mark. If there is no mark or unclear mark, the ZYB high-temperature gear oil pump is easy to use the balance weight, so that the weight difference between the piston and the connecting rod of each cylinder is as small as possible to facilitate the balance of the inertial force.
3 installation size requirements. S195KCB type stainless steel gear pump cylinder sleeve shoulder height above the plane value of the body is 0.04-0.17 mm; 495KCB stainless steel gear pump cylinder sleeve shoulder height above the plane value of the body is 0.02-0.10 mm. Multi-cylinder KCB type stainless steel gear pump cylinder sleeve shoulder high value should be consistent as much as possible, adjacent cylinder cylinder sleeve shoulder higher than the body plane value is not greater than 0.04 mm. It can improve the cylinder sealing performance and prevent the cylinder gasket from being damaged.
4 adjustment requirements. Such as fuel injector pressure and fuel supply adjustment requirements, the injector injection pressure of each cylinder as far as possible, the atomization state is consistent, the injection pressure difference is less than 5 kg/cm2, each cylinder rated oil supply requirements are uniform, not Uniformity is not more than 3%.
KCB stainless steel gear pump disassembly should pay attention to what matters? The structure and design are the products introduced into the Soviet Union in the early 1950s. They have the characteristics of simple structure, practicality and easy maintenance.
