Pay attention to the safety of lifting freight elevators in heavy rain

Pay attention to the safety of the use of lifting freight elevators in heavy rain. Quickly learn from the big fan of Hainan Industrial .

Now the weather is more changeable. So what should we pay attention to when the lifting freight elevator in use is raining? Today I will explain for you.

Lifting freight elevators, especially outdoor lifting freight elevators, should pay attention to safety protection measures in wet weather conditions such as rainy days. Under heavy rain, moisture and water vapor will erode the lifting freight elevator made of steel materials, which may rust the joints of the lifting freight elevator and cause inflexible operation, affecting normal work and operation.

It is also worth mentioning that such heavy rain is likely to be accompanied by strong winds. At this time, the lifting freight elevator working outdoors needs to take safety measures to prevent wind, so as to avoid the situation that the excessive wind makes it difficult to stabilize or even fall.

In heavy rain, the use and operation of the lifting freight elevator should be reduced as much as possible. If there is no way to avoid the need to use it, it must be operated by a professional operator, and the lifting freight elevator should be overhauled and maintained to maintain a safe operating environment.

When the user uses the lifting freight elevator, if the lifting of the freight elevator is unstable, they can find the reasons from the following aspects and establish a speed rigidity analysis formula for the lifting circuit. The flow rate into the hydraulic cylinder, that is, the flow rate through the one-way throttle valve is the flow rate through the throttle valve; the throttle valve shape of the throttle valve and the coefficient of hydraulic oil viscosity;

In addition, Hainan Wanhao Architectural Decoration Engineering Co., Ltd. believes that how to lift the AT of the freight elevator is the flow area of the throttling orifice (lifting without throttling); the outlet pressure of the hydraulic pump; Cylinder plunger area; the index determined by the shape of the throttle port, we can know the speed formula of the speed control circuit. When the throttle valve port area is constant, the output speed of the hydraulic cylinder will change with the load. The degree of influence of the load on the speed is expressed by the speed stiffness T: as the load increases, the output speed of the elevator actuator hydraulic cylinder decreases by a negative number; in order to make the advance a positive number, a negative sign is added to the formula. Substituting it into a hydraulic elevator, the greater the value of the speed stiffness of the inlet throttle circuit, the better the speed stability of the hydraulic circuit.
