Mesworth8-meteSeveral types: motor winding open circuit. When one phase of the motor winding is open circuit, or one of the parallel branches is open circuit, it will cause three-phase current imbalance and cause the motor to overheat.
Systems: explosion-proof electronic control system, remote control system, PIC system.
Mesworth.How to solve the problem of oil pipe leakage due to the sinking of the elevator? It may be caused by damaged seals or cracks in the oil pipe, resulting in a pressure drop and inability to support the oil pipe to a large height.
Carefully prepare a special construction plan for installation and construction,MesworthTen ton lifting cargo elevator, and provide safety technical disclosure to installation personnel.
.Hydraulic lifting platforms are widely used in factory maintenance, municipal construction, and decoration of hotels in industrial and mining enterprises, with reliable quality and perfect performance.
Characteristics of hydraulic elevators: Hydraulic lifting platform products are divided into curved arm type hydraulic lifting machines, scissors type hydraulic lifting machines, mast type hydraulic lifts, and straight arm type hydraulic lifts according to their working modes. Hydraulic elevator is a replacement product of folding arm elevator (lifting platform) and scissor fork elevator (lifting platform). It can be widely used for the decoration and decoration of stations, docks,MesworthChain type cargo elevator, airports, hotels, posts and telecommunications, garages, cleaning companies, public building facades, or the installation and maintenance of power systems, etc. This elevator has the advantages of light weight, self-propelled walking, electric starting, self supporting legs, simple operation, large working area, and especially the ability to cross obstacles for aerial work.
In addition, it is strictly prohibited to use a hammer during installation to prevent excessive axial or radial force from damaging the bearings or gears. Be sure to tighten the mounting bolts before tightening the tension bolts. Before installation, clean the anti rust oil on the motor input shaft, positioning boss, and elevator connection parts with gasoline or zinc sodium water. Its purpose is to ensure the tightness of the connection and the flexibility of operation and to prevent unnecessary wear and tear.
Before connecting the motor to the elevator, the elevator manufacturer should first make the motor shaft keyway perpendicular to the tightening bolt. To ensure uniform stress, first screw on the mounting bolts at any diagonal position, but do not tighten them. Then screw on the other two mounting bolts at diagonal positions, and then tighten the four mounting bolts one by one. After that, tighten the tightening bolts. All tightening bolts shall be fixed with a torque wrench according to the indicated fixed torque data and the use of elevators and lifting platforms shall be checked
Remove and disassemble the hydraulic elevator lowering valve, then install it and reinstall it.
What types of elevators are there? There are many types of such equipment blow out the plunger with compressed air, such as fixed lifting devices and vehicular lifting devices, depending on the form of movement. The so-called fixed lifting is generally installed in one place and fixed, and then lifting operations can be carried out. This type of lifting equipment is generally used more on the assembly line, and some large production lines need to lift the materials to a certain position when loading them, and then put them into production on the production line. A special lifting device needs to be fixed at a certain position on the production line.

Secondly, there should be no dirt on the friction surface. If there is any dirt,MesworthGuide rail chain type lifting cargo elevator, it should be washed off with gasoline or thinner; The reduction gearbox, gearbox, external meshing gear, and other parts of the equipment, must be tested according to the requirements in the table; Correct maintenance of the hydraulic guide rail elevator: Regularly inspect the wire ropes at various parts for broken wires and looseness. If any such phenomenon is found, replace it in a timely manner. The maintenance of the wire ropes must be carried out in strict accordance with the specifications; Check the connection condition of each part according to the braking rules and regulations. If there is any looseness, tighten it in a timely manner. Check the tightness of the connecting bolts of the equipment when the body is under pressure. All connecting shafts should be equipped with cotter pins; Check whether the operation of each mechanism is normal, whether there are noises and faults according to regulations, and promptly remove all faults; When installing, disassembling, and adjusting the rotating mechanism of the equipment, it is important to note that the reducer and the gear center line should be parallel, and the meshing clearance should be appropriate; Regularly conduct a comprehensive inspection of the equipment to see if there is any damage to the wires and cables, and if there is overheating of the motor. Replace the motor in a timely manner and eliminate the fault before continuing operation; Ensure that the bearings, distribution boxes, and brushes of the motor are kept clean, and that the travel switch points of each safety device must be safe and reliable.
Test the goods elevator every day to see if it can operate normally.
The hydraulic lifting platform can be divided into four wheeled mobile type, two wheeled traction type, vehicle modified type, vehicle type, auxiliary self-propelled type, and the lifting height varies from a meter to 1 meter.
Management Department.Systems: explosion-proof electronic control system, remote control system PIC system.
When working in a hot environment, pay attention to heat dissipation.
The elevator is a kind of elevator equipment composed of a walking mechanism, a hydraulic mechanism, an electric mechanism, and a support mechanism. The hydraulic oil forms a certain pressure by a vane pump, and enters the lower end of the hydraulic cylinder through an oil filter, flameproof electromagnetic directional valve, throttle valve, hydraulic control one-way valve, and balance valve. This allows the hydraulic cylinder to move upward and lift heavy objects. The return oil from the upper end of the hydraulic cylinder returns to the tank through the flameproof electromagnetic directional valve, and its rated pressure overflow valve is adjusted. Observe the reading value of the pressure gauge on the pressure gauge.
Mesworth.Hydraulic pump station: domestic lifting platform dedicated pump station, Italian imported pump station with external protective devices: organ m type, mesh type and iron plate sealed type.
In addition, it is strictly prohibited to use a hammer during installation to prevent excessive axial or radial force from damaging the bearings or gears. Be sure to tighten the mounting bolts before tightening the tension bolts. Before installation, clean the anti rust oil on the motor input shaft, positioning boss, and elevator connection parts with gasoline or zinc sodium water. Its purpose is to ensure the tightness of the connection and the flexibility of operation, and to prevent unnecessary wear and tear.
Precautions for using guide rail type elevators: Overloading and transporting flammable and explosive products are strictly prohibited.
