Larosh on the the short circuit current is much larger than the normal working current, which increases the copper loss of the winding, causing the winding to overheat or even burn out.
Does the cleanliness of the hydraulic station have relevant rules and requirements?
Larosh on the Yonghe River.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 enters the lower end of the hydraulic cylinder through an oil filter and a support mechanism. The hydraulic oil forms a certain pressure by a vane pump, 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.
.Corrosion prevention measures for the body of aerial work vehicles Attention to small scratches The paint surface of aerial work vehicles often corrodes. In addition to common collisions, scratches, and small rocks on the drive tire, there can also be a paint peeling point that can cause a small rust over time. Because most of these scars are small and easy to ignore. Therefore, regularly inspect the engine compartment lid and surrounding areas, and once found, go to a professional beauty shop for processing in a timely manner.
The load of this series of products is divided into 0.1 to 0.8 tons, and can also be customized according to user requirements, with a load of up to 10 tons.
Carefully prepare a special construction plan for installation and construction, and provide safety technical disclosure to installation personnel.
Purpose The hydraulic lift is widely used in various industrial enterprises and production lines such as automobile, container, mold manufacturing, wood processing, chemical filling,Larosh on the Yonghe RiverGuide rail lifting cargo elevator, etc., to meet the lifting requirements of different operation heights, and can be equipped with various table forms (such as ball, turntable steering, tipping, telescoping), and with various ways (separate, linkage, explosion-proof) it has the characteristics of stable and accurate lifting, frequent starting, and large load capacity, Effectively solve various lifting and lowering operation difficulties in industrial enterprises, making production operations free. Professional elevator factory has advanced technology, strict testing, more affordable prices, and more preferential treatment. Welcome to consult
The daily maintenance of guide rail type lifting equipment should pay attention to regular inspection and maintenance, and eliminate faults. Doing so is beneficial to improving work efficiency, extending the service life of the equipment, and ensuring the safety performance of the elevator.
Different. (Specific bearing capacity and lifting height can be designed and customized according to user requirements)
Application process.Outriggers: mechanical outriggers, hydraulic outriggers, ordinary hand cranking outriggers, and pull-out outriggers.

Motor connection error. When the triangular connection motor is mistakenly connected into a star shape, the motor still operates with full load, and the current flowing through the stator winding exceeds the rated current, leading to the motor stopping itself. If the stopping time is slightly longer and the power supply is not cut off, the winding will not only be severely overheated, but also burned. When a star connected motor is mistakenly connected into a triangle, or when several coil groups are connected in series into a single branch, the motor is mistakenly connected into two branches in parallel, both the windings and the iron core will overheat, and in severe cases, the windings will be burned.
Several 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.
Industry management.Nowadays, small and medium-sized enterprises are products with the idea of good quality and preferential prices.
Remove and disassemble the hydraulic elevator lowering valve, blow out the plunger with compressed air, then install it and reinstall it.
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
